Answer:

I live in a rural area which is surrounded by mountains and valleys. Near my home there is small forest area where there are hundreds of thick tall forests, algae and many other photosynthetic plants.

The atmosphere of that forest is very clean and refreshing because there is alot of oxygen being produced there due to alot of photosynthesis being done by all the lush green plants there.

Due to photosynthesis, carbon di oxide that is an environmental pollutant is maximum used by the plants and maximum. Oxygen is produced as a result of photosynthesis.

This causes the environment of not only that forest but my whole village very clean and fresh to breath. We are living a healthy life where there is a less prevalence of diseases or infections that are caused by environmental pollutants like Bronchitis, Lungs infection, neural disorders etc.

Therefore, even if there is not such an area near your home, we would suggest you to plant more trees in your backyard that will make the environment of not only your home but your area very fresh and clean.

Down syndrome is the answer.

Take a look at the other diseases to know why.

Lupus: a chronic autoimmune disease where the person's immune system is over active and begins to affect/damage healthy tissue. It can affect tissues all over the body.

Rheumatoid Arthritis: is also an autoimmune disease, not to be mistaken with osteoarthritis (wear and tear). It occurs when the person's immune system attacks the lining of the joints, resulting in swelling and eventually joint deformity.

Type-1 Diabetes: is also an autoimmune disease. It's when the body's immune system attacks and destroys beta-cells in the pancreas. These cells produce insulin, so destroying them results in diabetes.

Down's Syndrome: Although people with down's syndrome often have autoimmune disorders, down's syndrome is a birth defect caused by a chromosome irregularity (trisomy 21). It is not an autoimmune disorder.

Among Lupus, Rheumatoid arthritis, Type-1 Diabetes, and Down’s syndrome, the one that is NOT an auto-immune disease is Down’s syndrome. Auto-immune diseases are ones where the body's immune system attacks its own cells, unlike Down’s syndrome which is a genetic condition.

The question asks which of the listed conditions is not an auto-immune disease. Auto-immune diseases are conditions where the immune system mistakenly attacks the body's cells. This includes diseases such as Lupus, Rheumatoid arthritis, and Type-1 Diabetes. However, Down’s syndrome is not an auto-immune disease; it's a genetic condition that results when there is an extra chromosome 21.

Reproductive cells are haploid (have 1/2 the chromosomes), whereas somatic/body cells are diploid (have the full set of chromosomes)

This makes sense if you think about it. Using the example from the question, every dog has 78 chromosomes. This includes two of each (there are two chromosome 1's, two chromosome 2's, etc. This is visible in the karyotype attached). One set of these chromosomes were inherited from the mother, and one set from the father. Each parent contributed 39 chromosomes (one chromosome 1, one chromosome 2, etc.). If the dog in the question were to have 78 chromosomes in its sperm cells, it would contribute two sets to its offspring. When combined with the chromosomes in the egg cell, the offspring would end up with extra chromosomes. Therefore, both the sperm and the egg cells will have 39 chromosomes, one of each. When combined, they will produce offspring with 78 chromosomes, the proper number.

MECHANICAL WEATHERING:

Mechanical weathering is defined as a natural process. It occurs when big rocks are broken down into smaller rocks. Sometimes you will hear it referred to as “physical weathering.” There are lots of different things that can cause physical weathering. For example, temperature changes and rain can both cause weathering.

Mechanical weathering is the process of breaking down rocks into smaller particles through physical forces, which contributes to the formation of soil and clastic sedimentary rocks.

Definition of Mechanical Weathering

Mechanical weathering is one of the processes that break down rocks on Earth's surface into smaller particles. Unlike chemical weathering, it involves the physical disintegration of rocks without any change in their chemical composition. Mechanical weathering can occur due to temperature changes (which cause expansion and contraction in rocks), freeze-thaw cycles (where water in cracks freezes, expands, and then breaks apart the rock), or salt crystal growth. Formation of soil partly occurs as a result of mechanical weathering, where particles such as gravel, sand, and clay are produced from the disintegration of pre-existing rocks.

Over time, mechanical weathering contributes to the development of clastic sedimentary rocks through a process where broken down rock particles are transported and eventually settle in a new location. The understanding of mechanical weathering is essential for comprehending how landscapes and landforms evolve over time.

Ans.

In flowering plants, the male reproductive part or stamen is made up of a stack-like structure, known as filament and an ovule-like structure, known as anther. In anthers, microsporangia are present that produce pollen through mitosis.

Thus, 'if anthers are removed from a flower, it will not be able to form seeds as seeds are developed from zygote, that forms by the fusion of male gamete (pollen) and female gamete (ovum).'

Answer:

This flower will not be able to produce seeds.

Explanation:

The anther is a structure composed of two teak (halves), is fertile and responsible for the production of pollen grains, pollen grains are responsible for the generation of seeds when it comes into contact with the ovary of another plant. Thus, if a flower loses all its anthers, it means that it will not be able to generate pollen and will not be able to produce seeds.

Still in the juvenile state the anther begins the production of pollen. Each teak has two pollen bags (cavities) lined with a layer of nutrients called “tapetum”. It is still in this juvenile phase that the mother cells of the pollen grains are found, resting in each pollen sac. The anther has an outer layer, the epidermis, and an inner layer, the endothecium.

Briefly explain how cells use a high-calorie molecule such as glucose. A calorie is enough energy to heat one gram of water by one degree celsius. Cells use molecules such as glucose by breaking them down and using they energy they provide. Write a chemical equation for cellular respiration

Final answer:

A calorie is a unit of heat energy, and kilocalories are typically used to measure the energy content in food. Glucose, a high-calorie molecule, is broken down via cellular respiration to provide energy in the form of ATP, which can be used by cells.

Explanation:

A calorie is the amount of heat energy required to raise the temperature of one milliliter of water by one degree Celsius (°C). In the context of biology and human physiology, we refer to kilocalories (1000 calories) when talking about food energy, and often simply use the term calorie with a capital 'C' to mean kilocalorie.

Cells use glucose, a high-calorie molecule, as a primary source of energy. Glucose is a compact form of energy that is easily transported in the blood and taken up by cells. The chemical formula of glucose is C6H12O6, and the breakdown process by which energy is released is called cellular respiration. During cellular respiration, glucose reacts with oxygen to produce carbon dioxide, water, and energy, which can be summarized by the equation: C6H12O6 + 6O2 → 6CO2 + 6H2O + energy. This energy is then stored as ATP (adenosine triphosphate), which is readily usable by the cell for various biological processes.

So, since the trait is eye color, let's use E to represent the dominant allele (brown) and e to represent the recessive allele (blue).

I've attached a Punnett square, but let me real quick explain how I set it up. We know that both parents are heterozygous, which means that they have one of each allele. So that gave us the two sides. Then I filled in the boxes (I assume you've leaned how to do this, if message me and I can explain it).

Looking at the results we can see that 1/4 of the offspring are EE, 1/2 are Ee, and 1/4 are ee. Since the blue allele (e) is recessive, it'll only be expressed if no dominant brown alleles (E) are present. Therefore, only the ee genotype will exhibit blue eyes. So, 1/4 or 25% of the offspring will have blue eyes.

Hope that helps! If you need clarification or anything feel free to message me :)

When both parents are heterozyjous for brown eyes (Bb), there is a 25% chance their offspring will have blue eyes (bb). The chance of a green-eyed child from brown-eyed heterozygous parents is due to both carrying the green trait recessive to brown but dominant to blue.

For eye color, the brown allele (B) is dominant over the blue allele (b). If both parents are heterozygous for eye color (Bb), the expected percentage of their offspring with blue eyes can be calculated using a Punnett Square. The Punnett Square for this scenario would look like this:

After filling out the Punnett Square, the genotype ratio is:

Therefore, the percentage of offspring with blue eyes would be
25% (the one bb out of four possible outcomes).

Regarding the scenario with the green-eyed child, the correct statement among the given options is that both parents are heterozygous, having the green trait on the green-blue eye gene. This means the parents have the genotype Gg, where 'G' might represent the green allele, which is recessive to the brown eye allele but dominant over the blue eye allele.

Answer:

Option (D)

Explanation:

Scoria is an igneous rock that is dark in color. When volcanic eruptions take place, the magma comes out to the surface forming lavas and releasing various gases. These lavas due to their reducing temperature start to get solidified. During this process, the air bubbles trapping these dissolved gases get solidified and forms a rock which is commonly known as scoria. They are easily marked by their vesicular structure. They are formed at or near the surface of the earth and they are comprised of basaltic rock types.

Thus, the correct answer is option (D).

There are various types of rocks. Scoria is a type of igneous rock that forms at or near the Earth's surface when volcanic lava cools rapidly while gas is still trapped inside, resulting in a vesicular or spongy appearance.

The rock that you refer to, which is sometimes called scoria and has a vesicular texture, is an igneous rock. It forms at or near the Earth’s surface when lava ejected from a volcano solidifies rapidly with gas still trapped inside, which gives it the vesicular or spongy appearance. Therefore, the correct choice is D) an igneous rock, at or near the Earth's surface.

Charles Darwin thats the answer

Final answer:

Charles Darwin is known as the Father of Evolution for formulating the theory of evolution by natural selection, which elucidated the development of life's diversity through common descent.

Explanation:

The scientist known for his work with natural selection and often referred to as the Father of Evolution is Charles Darwin. Darwin's pivotal role in biology stems from his theory of evolution by natural selection, which represents a fundamental unifying concept for understanding the diversity and adaptation of life on Earth. A British naturalist, Darwin not only contributed to evolutionary theory, but also influenced fields such as psychology through the functionalist school of thought. Moreover, his observations and insights were eventually compiled into his renowned work, 'Origin of the Species', conveying the revolutionary idea that all species of life have descended from common ancestors over geological time.

Part of Darwin's genius lay in realizing that selective breeding practices in agriculture were analogous to a natural process. He introduced the concept that competition for limited resources in nature would 'select' individuals better adapted to their environment, a process he termed 'natural selection'. This groundbreaking idea was the result of over two decades of meticulous research and global exploration.

Final answer:

Alfred Wegener's continental drift hypothesis led to the theory of plate tectonics, which suggested a past supercontinent named Pangaea. Mountain ranges most likely prompted the theory, and Wegener faced ridicule because he lacked a mechanism for continental movement. A Martian day, or sol, is equivalent to 24 hours and 39 minutes.

Explanation:

The theory of plate tectonics originated from Alfred Wegener's idea of continental drift, which he proposed in the early 20th Century. Wegener's hypothesis was based on several key observations including the jigsaw-puzzle fit of the continents, similar fossils found across oceans, matching mountain ranges in separate continents, and paleoclimate evidence suggesting the joining of continents. His concept of a supercontinent Pangaea, which existed around 200 million years ago, was initially rejected because he could not explain how the continents moved. It wasn't until the 1960s, with the discovery of seafloor spreading, that continental drift and plate tectonics were widely accepted, revolutionizing our understanding of Earth's geology.

The geological features that most likely prompted the development of the theory of plate tectonics are mountain ranges (C), because they provide visible evidence of the immense forces and the movement of the Earth's crust involved in the theory.

The correct evidence supporting plate tectonics through data collected at the sites of sea floor spreading is: A) paleomagnetic reversals in specific areas of the sea floor, B) a large occurrence of earthquakes along specific lines within the Earth's oceans, and D) an increase in the thickness of ocean crust as you move away from the area of spreading. The option that does not support this is C) the presence of unique species in remote locations, such as Australia and New Zealand.

One of the main reasons Wegener's theory of continental drift received ridicule from the scientific community (C) was that he did not provide a mechanism on how the continents actually moved.

A Mars day, which is equivalent to 24 hours and 39 minutes, is known as a sol (A).

Single-celled organisms are made of only one cell. Multi-cellular organisms, such as plants and animals, have a higher degree of specialization where the cells work together and function Single-celled organisms are made of only one cell. Multi-cellular organisms, such as plants and animals, have a higher degree of specialization (the adaptation of an organism or organ to a special function or environment)where the cells work together and function to create a living organism.

In multicellular organisms, cells are specialized and communicate with distant cells while in single-celled organisms, the single cell performs all functions and communicates with nearby cells. Multicellular organisms require more time for signal transduction due to their complexity.

Cells in multicellular organisms differ from those in single-celled organisms in several key ways. Firstly, multispecies organisms coordinate between distantly located cells, whereas organisms with only one cell communicate only with nearby cells. This is due to the fact that multicellular organisms use receptors for signaling, whereas single cells often communicate through fusion with nearby plasma membranes.

Another key difference is specialized function. In multicellular organisms, cells are specialized, meaning different cells have different functions. For example, a muscle cell is quite different from a liver cell. This specialization is a result of different sets of genes being expressed in different cells. However, all cells, regardless of their type, have to convert energy in sugar molecules into ATP for their own use. In contrast, in single-celled organisms, the lone cell must perform all the functions needed for the organism. All genes can be turned on and off at different times or in response to environmental changes.

Lastly, multicellular organisms require more time for signal transduction in comparison to single-celled organisms due to the complexity and compartmentalization in multicellular organisms.
