Answer:
The correct option is A) make food.
Explanation:
Photosynthesis can be described as a process by which organisms like plant and some algae make their own food. They use light energy from the sun to convert carbon dioxide and water into glucose and oxygen. Oxygen is the by- product of this reaction. Hence, option A is correct.
Other options are wrong because photosynthesis is not a process by which energy can be extracted from food or it is not a process by which excretion of waste occurs. Neither is it a process of reproduction.
The single-celled algae and multicellular plants A. make food. Therefore , A. make food is correct.
Photosynthesis is a vital biological process in which both single-celled algae and multicellular plants harness energy from sunlight to convert carbon dioxide and water into glucose.
This transformative process occurs in chloroplasts, where pigments such as chlorophyll capture light energy.
This captured energy facilitates the synthesis of carbohydrates, serving as the primary source of organic nutrients for these organisms.
During photosynthesis, light energy is converted into chemical energy, stored in the form of glucose.
This glucose not only serves as a direct energy source for the organisms but also acts as a foundational building block for other essential organic molecules.
By utilizing carbon dioxide and releasing oxygen as a byproduct, photosynthesis plays a crucial role in maintaining atmospheric balance.
While photosynthesis is indeed a process vital for generating sustenance, it is not directly involved in waste elimination, energy extraction from food, or reproduction.
The primary focus is on the synthesis of organic compounds to support the metabolic and growth needs of these organisms.
option A, "make food," accurately encapsulates the core function of photosynthesis for both single-celled algae and multicellular plants.

Mitosis is divided into phases.
A phase of mitosis is shown. The chromatids separate from each other and are being pulled to the opposite ends of the cell.
Which phase of mitosis is shown in the diagram?
anaphase
metaphase
telophase
prophase
The phase of mitosis shown in the diagram where chromatids separate from each other and are being pulled to the opposite ends of the cell is **anaphase.** The correct option is 1.
During anaphase, the centromere that holds sister chromatids together splits, allowing the chromatids to become individual chromosomes. These chromosomes are then pulled apart toward opposite ends (poles) of the cell by the contraction of spindle fibers. The movement of chromatids is facilitated by the shortening of microtubules within the spindle apparatus.
The key events of anaphase include:
1. **Separation of Sister Chromatids:** The chromatids, which are identical copies of each other, are separated as the centromere divides.
2. **Movement Towards Poles:** The separated chromatids, now individual chromosomes, are pulled towards the opposite poles of the cell by the spindle fibers. This ensures that each daughter cell will receive a complete set of chromosomes.
**Other Phases:**
- **Prophase:** This phase involves the condensation of chromatin into visible chromosomes, the breakdown of the nuclear envelope, and the formation of the mitotic spindle.
- **Metaphase:** During metaphase, the chromosomes align along the center of the cell, known as the metaphase plate. The spindle fibers attach to the centromeres of each chromosome.
- **Telophase:** In telophase, the separated chromatids (now chromosomes) arrive at the opposite poles and begin to decondense back into chromatin. The nuclear envelope starts to reform around each set of chromosomes, creating two distinct nuclei.
**Cytokinesis** follows mitosis and involves the division of the cell's cytoplasm and other organelles, ultimately producing two daughter cells.
In the diagram where chromatids are being pulled apart and moving towards the cell's opposite ends, it's indicative of **anaphase** of mitosis. This phase is crucial for ensuring that each daughter cell receives an identical set of genetic material.

After injecting the mice with both bacteria, what question did Griffith ask him self
Answer:
Griffith performed an experiment on the mice to test two different strains of bacteria. One of them was virulent and the other was non virulent. The result depicted that the non virulent strain transformed into virulent strain through the process of transformation.
Explanation:
Different mice were injected with different combination of strains. One of the strain was a virulent one, III-S and the other one was II-R which was non virulent. Both the strains were taken from Streptococcus pneumoniae. The following observations were made:
1. In the first mice only simple III-S was introduced. The mouse died.
2. In the second one, heat killed III-S was injected. The mouse survived as the virulent portion was killed.
3. In this one II-R was introduced. Since it was an non virulent strain, the mice did not die.
4. In this he added both heat killed III-S and II-R. The mouse died and this perplexed Griffith. He wondered what had happened since the non virulent form and heat killed virulent form should have not harmed the mice.
Later he found out that the DNA of the Heat killed III-S was imbibed by the II-R form. The bacteria had 'transformed' and as a result the mice died.

what is a renewable resource and a non renewable resource?
Answer:
Renewable and Non-renewable resources are discussed below:
Renewable energy: are those energy that can be used again and again and it re-new after a short period of time. it is generally defined as that kind of energy resources that can be renewed naturally.
Renewable sources of energy can replace conventional sources of energy which produce harmful gasses which is harmful as well as costly.
Non-renewable: resources are those resources which can not be re-use or re-produce it is one-time use only and it takes a long period of time get re-produce,
Non-renewable sources of energy are also not good for the environment burning fossil fuels harm our environment.
Final answer:
Renewable resources, like sunlight and wind, are replenished naturally and are in endless supply, while nonrenewable resources, like fossil fuels and minerals, exist in fixed amounts and can be used up.
Explanation:
Renewable resources are those that can be replenished by natural processes at the same rate as they are consumed by humans. Examples of renewable resources include sunlight, wind, and the rising and falling of ocean tides. These resources are essentially in endless supply and can also be considered sustainable when used in a manner that doesn't prevent future generations from meeting their needs. Sustainable examples include sustainably harvested wood, cork, bamboo, and certain agricultural crops.
Conversely, nonrenewable resources exist in fixed amounts and can be depleted. These resources, such as fossil fuels (petroleum, coal, and natural gas), are formed over millions of years and therefore cannot be replaced as quickly as they are used. Other nonrenewable resources include precious metals and minerals. With the current rate of consumption, resources like petroleum and coal could be exhausted within a few decades or a few hundred years, respectively. Nuclear power is also considered nonrenewable due to the finite nature of uranium and the production of harmful wastes.
Understanding the difference between renewable and nonrenewable resources is essential for sustainable management and the development of alternative energy sources, which often utilize renewable resources to replace fossil fuel use.

If a man with Menkes disease (XMY) has children with a woman who does not carry the disorder (XX), all daughters will be carriers of the disorder (100% chance), and no sons will be affected because they inherit their father's Y chromosome.
The disorder is usually manifested in males who have only one X chromosome (XY). A female (XX) with one affected X chromosome is typically a carrier but does not show symptoms because the healthy X chromosome compensates for the faulty one. When it comes to the inheritance patterns for sex-linked disorders like Menkes disease:
A man with Menkes disease (XMY) will pass on the Y chromosome to his sons, so they will not inherit the disorder.His daughters will inherit his unaffected X chromosome and will not have the disease; however, they will certainly be carriers if their mother is healthy (XX).Therefore, if a man with Menkes disease has children with a woman who does not carry the disorder (XX), all daughters will be carriers (heterozygous for the condition), and no sons will be affected. In summary, if they have a daughter, there is a 100% chance that she will be a carrier for the disorder.What is a gene mutation that affects multiple nucleotides?

What is the effect of iron levels on rate of cellular respiration?
Answer:
The effects of iron deficiency on cell culture growth, cell respiration, mitochondrial oxidative properties, and the electron transport chain were studied with suspension-cultured sycamore (Acer pseudoplatanus L.) cells. Iron deprivation considerably decreased the initial growth rates and limited the maximum density of the cells. Under these conditions, the cells remained swollen throughout their growth. The absence of iron led to a steady decline in the uncoupled rate of O2 consumption. When the uncoupled rate of O2 uptake closely approximated the respiratory rate, the cells began to collapse. At this stage, the level of all the cytochromes and electron paramagnetic resonance-detectable Fe-S clusters of the mitochondrial inner membrane were dramatically decreased. Nevertheless, it appeared from substrate oxidation measurements that this overall depletion in iron-containing components solely disturbed the functioning of complex II, whereas neither complexes I, III, or IV, nor the machinery involved in ATP synthesis, was apparently impaired in iron-deficient mitochondria. However, our results suggest that the impairment of complex II resulted in a strong reduction of the overall capacity of the mitochondrial electron transport chain, which was responsible for determining the rate of endogenous respiration in sycamore cells. Finally, this situation led to a depletion of various energy metabolites that could contribute to the premature cell death.
Explanation:
Iron levels are critical to the rate of cellular respiration due to their role in hemoglobin, myoglobin, and cytochromes, which are involved in oxygen transport and electron transfer. Abnormal iron metabolism, like anemia or iron overload, can lead to impaired cellular functioning and influence respiration efficiency. Maintaining proper iron levels supports optimal cellular respiration.
Explanation:
The effect of iron levels on the rate of cellular respiration is significant due to the role of iron in various biological processes. Iron is a critical component of hemoglobin, myoglobin, and cytochromes which are involved in oxygen transport and electron transfer within cells. Adequate iron levels are necessary for the efficient functioning of these proteins and hence, support optimal cellular respiration.
Abnormal iron metabolism, such as anemia or iron overload, can affect the cellular respiration rate. Low iron levels can lead to reduced oxygen transport to tissues, affecting ATP production during aerobic respiration. Conversely, iron overload can lead to oxidative stress and damage cellular components, impairing respiration efficiency. Moreover, in conditions like methemoglobinemia, where the iron in hemoglobin is oxidized from ferrous (Fe²⁺) to ferric (Fe³⁺), the oxygen-carrying capacity of hemoglobin is compromised, which can also impact cellular respiration.
Therefore, maintaining normal serum iron concentration and preventing abnormal deposition of iron in tissues are crucial for the proper function of cellular respiration pathways.

Lipids and carbohydrates differ in which of the following fundamental respects?
Answer:
Carbohydrates are hydrophilic whereas Lipids are hydrophobic.
Explanation:
Carbohydrates can be most commonly understood as hydrates of carbons. They generally contain more than two carbon atoms and are easily soluble in water, thus giving them the characteristics of hydrophilic compounds. Sugar and glucose are some of the important examples of carbohydrates.
On the other hand, lipids comprise a polar region, which attracts water and a much larger non-polar region, which repels water. This non-polar region dominates the polar region of lipid molecules thus making it a hydrophobic compound. Oils, fatty substances, steroids, and waxes are some of the important examples of Lipid molecules.
A ___ is a kind of lipid that can store energy for a long period of time. These lipids are made up of long chains of carbon and oxygen atoms bonded to a backbone structure.
Answer:
chlorophyll
Explanation:
A Triglyceride is a kind of lipid that can store energy for a long period of time.
Triglycerides are a type of lipid that can store energy for an extended duration. They consist of long chains of carbon and oxygen atoms bonded to a glycerol backbone structure. These molecules serve as the primary form of energy storage in the human body and many other organisms. Each triglyceride molecule contains three fatty acid chains attached to the glycerol backbone. The carbon-carbon and carbon-hydrogen bonds within these fatty acids store a significant amount of chemical energy, which the body can access when needed.
When an organism requires energy, enzymes break down triglycerides into their constituent fatty acids, releasing energy for cellular processes. Excess triglycerides can be stored in adipose tissue, contributing to body fat. While triglycerides are vital for energy storage, elevated levels in the bloodstream can be associated with health issues, such as obesity and heart disease.

It is important for us to keep our water supply clean and chemically balanced, so that it is potable and we can drink it. Having the right pH level is a part of this. What pH level should drinking water have
Answer:
The pH level of drinking water must fall within the range, 6.5-8.5 because is neither acidic nor alkaline enough to be dangerous in the human body.
Explanation:
The pH level is an indicator of acid-base equilibrium, and shows whether a substance is acidic or alkaline. The pH scale ranges from 0-14, where a pH value of 7 means the substance is neutral. The levels less than 7 is considered as acidic and the levels greater than 7 is considered as alkaline.
The pure water has a pH value of 7. The normal pH range of surface water systems is 6.5 to 8.5, and that of groundwater systems is 6 to 8.5. According to EPA (Environmental Protection Agency) standards, the pH value of drinking water must fall within the range, 6.5-8.5 .This water is safe to drink as it is neither acidic nor alkaline enough to be dangerous in the human body.
Water having a pH value less than 6.5 is considered as soft and acidic, and it can be corrosive and filled with toxic metals while water with a pH value higher than 8.5 is hard and alkaline, and poses less of a health risk than acidic water but can taste bad and leave scale deposits on dishes, sinks etc.
