Answer:

C.) Organisms which are able to survive in the deepest depths of the ocean must have adaptations that allow  them to live in cold dark environments under a lot of pressure.

Explanation:

Organisms which live in the deepest depths of the ocean receive little sunlight, so they must adapt to live in those cold conditions with a lot of pressure constantly on them. Basically, if a creature lives in a certain part of the ocean, they are most likely adapted enough to live in the conditions that their home has for them.

The best statement describing the distribution of life in the ocean is that organisms living in the deepest depths must have adaptations for survival, such as the ability to withstand cold, dark, and high-pressure conditions.

The distribution of life in the ocean varies depending on factors like depth, temperature, light availability and nutrient availability. Not all aquatic species can survive in all ocean conditions. Thus, the best statement that describes the distribution of life in the ocean would be C), which states, 'Organisms which are able to survive in the deepest depths of the ocean must have adaptations that allow them to live in cold dark environments under a lot of pressure.' The extreme conditions of the deep ocean require specific adaptations for survival.

For example, many deep-sea organisms possess adaptations such as bioluminescence (the ability to create their own light), increased pressure tolerance and ability to deal with cold temperatures. Other examples of adaptations include having a slow metabolism to conserve energy, as food is scarce in those depths.

Answer:

(A) It is measure of how far an object moves in a certain time.

Explanation:

According to law of conservation of matter, mass can neither be created nor destroyed. Therefore option (B) is the correct answer.

The fundamental idea that underlies the law of conservation of mass is, a body's mass remains constant while it is in motion. This can be expressed in rate form as the rate at which the mass of a body changes over time to zero.

For instance, when coal is burned, the carbon atom in it transforms into carbon dioxide. The carbon atom transforms from a solid to a gas, yet its mass remains constant.

This proves that in a chemical process, no new or lost atoms are created. Instead, the atoms combine in a variety of ways to create goods.

Hence , option (B) which states that mass is conserved is the correct answer.

Answer:

C

Explanation:

The sample that would be most useful in identifying the person who committed the crime would be option C: drops of blood found at the crime scene, as blood contains genetic material in the form of DNA.

DNA (deoxyribonucleic acid) is a molecule found in cells that contains genetic information. DNA is unique to each individual, except in the case of identical twins, and can be used to identify a person through a process called DNA profiling or DNA fingerprinting.

When blood is left at a crime scene, it contains DNA that can be analyzed by forensic scientists to create a DNA profile of the person who left the blood. This is usually done through a process called PCR (polymerase chain reaction), which amplifies the DNA found in the sample so that there is enough material for analysis. Once the DNA has been amplified, it can be analyzed to create a DNA profile.

Hence, the sample that would be most useful in identifying the person who committed the crime would be option C: drops of blood found at the crime scene, as blood contains genetic material in the form of DNA.

The theory of evolution by natural selection suggests that variation within populations facilitates adaptation and survival as environmental conditions change. Natural selection favors individuals with traits suitable for survival and reproduction in their environment, leading to evolutionary changes over time. Thus, variation is critical for the evolution of populations and species.

Part of the theory of evolution by natural selection is that all animals in a population do not display identical traits, as there exists natural variation within the population. This variation is essential because it provides a pool of different characteristics from which natural selection can occur. Individuals within a population that have traits better suited for survival and reproduction in their environment are more likely to pass on these favorable traits to their offspring, shaping the population over time. If an environmental change occurs, the presence of variation increases the likelihood that some individuals will already possess traits that make them apt to survive the change, thus allowing the population as a whole to persist. Natural selection plays a critical role in how populations evolve and how new species may arise, especially when populations become genetically isolated due to various factors like geographic barriers.

It's important to note that a completely homogeneous population where all individuals are genetically identical clones would have zero evolvability, as there would be no divergent traits for natural selection to act upon in the face of environmental changes. Therefore, variation within populations is crucial for the evolution of populations and for the survival of species through changing conditions.

In summary, the theory of evolution by natural selection explains that the inherited traits of a population change over time, influenced by the organism's ability to survive and reproduce in the environment. The uncontrolled growth potential of populations is checked by various external factors like predation and competition, which also play a role in evolution as they affect the survival and reproductive success of individuals.

The correct option is C because Small changes add up over many generations.

The concept of gradual change over time through the accumulation of small variations within populations. These variations can be inherited and can lead to changes in the characteristics of populations over successive generations, driving the process of evolution.

The other options are incorrect because

A. All animals in a population are able to reproduce: While reproduction is necessary for evolution, not all individuals in a population may be equally successful at reproducing.

B. Adaptations cannot be passed along to later generations: This contradicts the core principle of heritability. Traits that are beneficial for survival and reproduction can be passed on to offspring.

D. Animals have no variation among themselves: Variation is essential for natural selection to work. Individuals within a population exhibit differences in traits, which provide the raw material for evolution.

The complete Question is

2) we concluded from the above study is that most of the students said that pickles made from mango are sour in taste.

Explanation:

The possible hypothesis is that the pickles are sour in taste because in pickles mangoes are used when they are green in color and have sour taste so we can say that the pickles which is made from these mangoes are also have sour taste. There is a variation in opinion between students about the taste of mango pickle. Most of the students found the pickle sour in taste so we can choose the result of the majority of the students and make hypothesis accordingly.

1. Possible hypothesis: The taste perception of mango pickle may vary among individuals.

2. Conclusion: Taste perception of mango pickle is subjective, with some finding it sour while others perceive it as tasteless.

1. Possible hypothesis of the study:

  - The hypothesis could be that the taste perception of mango pickle varies among individuals based on their sensitivity to sour flavors or other factors such as genetic predispositions, previous exposure to similar flavors, or individual taste preferences.

2. Conclusion from the study:

  - The study suggests that taste perception of mango pickle is subjective and varies among individuals. Majority of the participants (7 out of 10) perceived the pickle as sour, indicating that the sour taste is predominant. However, a minority (3 out of 10) found it tasteless, suggesting individual differences in taste perception.

  - Further research could investigate the factors influencing taste perception and preferences to better understand the variability in individuals' responses to food flavors.

He believed that over time, the new generations of finches adapted to the islands, resulting in variation in their offspring's beaks. Scientists can use different evidence of evolution to prove this, such as the observation of a graded series of beak sizes and shapes in the Galapagos finch species, the resemblance of the finches to a mainland finch species, and the correlation between beak shape and food acquisition.

Answer:

It has more water molecules causing pressure to grow.

Explanation:

The pressure in the matrix, referring to a space within plant cells, is high due to the osmotic process, involving the movement of water from a lower to higher concentration. This builds up pressure in the cell, including the matrix, giving the plant rigidity.

In the context of biology and specifically plant physiology, the term 'matrix' typically refers to the space within the chloroplast where the light-independent reactions of photosynthesis take place. The pressure in the matrix is high due to the osmotic process - the movement of water from a lower concentration to a higher concentration across a semi-permeable membrane. This process creates a build-up of pressure in the plant cells, including in the matrix.

The water-filled central vacuole exerts pressure against the cell wall - this is known as turgor pressure - giving the plant rigidity. As water moves into the cell, it increases the volume of the cytoplasm and the vacuole, thereby increasing the pressure within the cell, including the matrix.

Both prokaryotes and eukaryotes have a liquid cytoplasm

Prokaryotes and eukaryotes both have liquid cytoplasm where cell metabolism occurs. They do not share other features like Golgi apparatus, nuclear membrane, or mitochondria - these are exclusive to eukaryotes. option B is the correct answer .

Prokaryotes and eukaryotes, despite their differences, share some common features. The main commonality between these two types of organisms is that they both have a liquid cytoplasm, where all of the cell's metabolic events occur. Neither a Golgi apparatus, a nuclear membrane, nor mitochondria are common to both, as these are typically features of eukaryotic cells. For instance, a nuclear membrane, which encloses the genetic material, is absent in prokaryotic cells and the Golgi apparatus, a packaging center for proteins, is also exclusive to eukaryotes. Similarly, mitochondria, the powerhouse of the cell, are only found in eukaryotes.

Final answer:

Asexual reproduction in plants often occurs through roots or other plant parts such as stems and leaves, with roots being a common method. For instance, dandelions reproduce asexually via roots, leading to genetically identical clones of the original plant.

Explanation:

In plants, asexual reproduction can occur through various organs such as leaves, stems, and roots. However, roots are commonly used for this type of reproduction. For example, the dandelion uses its roots for asexual reproduction, and woody trees like poplars and aspens can send up new stems from their roots. This can eventually lead to the creation of an entire grove of trees that are clones of the original plant. A noticeable advantage of asexual reproduction is that when cuttings or buds are taken from an adult plant or plant parts, the resulting plant will grow into an adult faster than a seedling. Many plants, like garlic and strawberries, also use underground storage organs like bulbs, corms, tubers, and runners for asexual reproduction.
