2. "Natural selection is usually thought of as an agent of change in populations, but it can also act to maintain the status quo."
In a short, written response, analyze and evaluate this statement. Include the range of responses of a population to changes in the environment, such as differential reproductive success, the adaptation and development of diversity in and among species, and the change in populations.
Answer:
Those organisms survive and maintain its population who are chosen by natural selection.
Explanation:
This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.

If you were asked to determine if a cell is a prokaryote or eukaryote, the presence of which characteristic would be the best indicator? point
Answer:
Nucleus
Explanation:
Prokaryotic and Eukaryotic cells are very different from each other and can be distinguished by various characteristic.
But the best indicator that determine whether a cell is a is a prokaryote or eukaryote is the presence of nucleus. Prokaryotic cell do not contain nucleus and their DNA is found in cytoplasm while Eukaryotic cell contains membrane bound nucleus and their DNA is found in nucleus.
Hence, the presence of nucleus would be the best indicator.
Choose a statement that explains why competitive exclusion occurs between different species.
Limited resources are easily shared.
There are unlimited resources in the ecosystem.
Competition decreases the health of all animals.
One competitor is best at using a limited resource.
The statement "Limited resources are easily shared" is the one correct about the competitive exclusion between different species.
What is competitive exclusion?It is the result of the competition in which a species is expelled by another more efficient species from a part of the available habitat.
Characteristics of the competitive exclusionThe competitive exclusion principle states that two species cannot occupy the same ecological niche in the same habitat.If there are limited resources, eventually one species will exclude the other, given a certain period of time, through “competitive exclusion”.Therefore, we can conclude that the competitive exclusion states that two species occupying the same niche cannot coexist in the long term since they would enter into competition for limited resources.

Why do some plants perform C4 photosynthetic pathways instead of the more common C3 pathway?
Answer:
c4 plants are better adapted to tropical climate.and C4 plants effectively obtains Co2 even when present in low concerntration.this is bc co2 has high affinity for c4 organic acids present in C 4 plants.because of presence of C4 organic acids,plants can tolerate saline and acidic soils.they are able to maintain high area Co2 fixation because of compactly arranged mesophyll cells.
Plants may withstand acidic and saline soils thanks to the presence of C4 organic acids. Because the mesophyll cells are packed closely together, they can continue to fix a large amount of CO2.
What is photosynthetic?The process by which plants convert carbon dioxide, water, and sunshine into oxygen and sugar-based energy is known as photosynthesis.
Photosynthesis is a process used by plants and other living things to convert light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
Tropical climates are better suited to c4 plants. even in low concentrations, C4 plants can successfully absorb CO2. This is because the c4 organic acids found in C4 plants have a strong affinity for co2. Plants may withstand acidic and saline soils thanks to the presence of C4 organic acids. Because the mesophyll cells are packed closely together, they can continue to fix a large amount of CO2.

Which product is the result of light reactions in photosynthesis? O A. Water B. Glucose O c. Carbon dioxide OD. Oxygen
Answer:
D. Oxygen
Explanation:
Plants absorb carbon dioxide (CO2) and release oxygen for humans and animals to breathe in. Afterward, they'll release CO2 for plants to absorb, which forms a cycle.
Answer:
Oxygen
Explanation:
Both light dependent and light independent reactions in photosynthesis create glucose. But, only light dependent reactions convert carbon dioxide to oxygen.
Light independent: Carbon dioxide + water --> ATP and NADP(Energy/Glucose) and water
Light dependent: Carbon dioxide + water + light --> Glucose(ATP and NADP), water, and oxygen

Explanation:
Plant cells are different from the animal cells in their basic structure such as the cell wall which is absent in the animal cell, chloroplast is also found in the plant cell which is not present in animal cell.
What are Plant cells?Plant cells have a rigid cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a layer which is present outside the cell membrane and surrounds the cell, it provides the structural support and protection.
The central vacuole is present in the plant cell and it maintains turgor pressure against the cell wall. The central vacuole is a large vacuole found inside of plant cells. It is a sphere which is filled with fluid and molecules inside a cell. The central vacuole stores water.
Chloroplasts are the organelles which are responsible for the process of photosynthesis, are in many respects similar to mitochondria. Both the organelles including chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, and also contain their own genetic systems, and replicate by division.

Which characteristics do birds and mammals share? Check all that apply.
A. Both give birth to live young.
B. Both are endotherms.
C. Both have hair or fur.
D. Both produce milk to feed their young.
E. Both are vertebrates.
Answer:
B and E
Explanation:
The correct answer would be that both birds and mammals are vertebrates and are also endothermic.
Both birds and mammals belong to the same animal kingdom. They also belong to the same chordate phylum but belongs to different classes under the phylum. However, they both belong to the same sub-phylum Vertebrata - a group of chordates with the vertebral column.
Birds (aves) and mammals represent different classes of animals. Birds lay eggs that later hatch when conditions are right to give rise to their young ones. Mammals, on the other hand, give birth to their younger ones and are able to produce milk through their mammary gland to feed them. The body of mammals is characterized by the presence of hairs that help insulate the body making them to be homoiothermic, unlike birds that of birds, where hair is replaced with feathers.
However, both birds and mammals are endothermic, that is, they both maintain a fairly constant body temperature irrespective of the temperature of their environment.
The correct options are B and E.
Both are endotherms and vertebrates. Therefore option B and E is correct.
Birds and mammals share the characteristics of being endotherms and vertebrates.
Endotherms are animals capable of regulating their body temperature internally, which allows them to maintain a relatively constant body temperature even in changing environmental conditions.
Both birds and mammals are warm-blooded, which enables them to be active and maintain their metabolism efficiently.
Additionally, birds and mammals are vertebrates, meaning they possess a backbone or vertebral column. This structural feature provides support and protection for the spinal cord and allows for efficient movement.
While birds and mammals have other unique characteristics, their endothermic nature and vertebrate status are significant similarities that contribute to their adaptability and success in diverse ecosystems.
Therefore option B and E is correct.
