Answer:
Bit by bit. They could not move fully to land until plants did it first. We can see intermediate forms like lungfish and mudskippers. Amphibians came next. They only need water for their eggs and tadpoles, and some have avoided that too. The amniotic egg, developed by the first reptiles, made it possible to colonize the land away from water. Arthropods and mollusks followed their own, similar sequence of steps.

1. What is an ecosystem?
2. What are some examples of nonliving things in an ecosystem?
3. What are some factors that could affect the number of organisms in an ecosystem?
4. Why might organisms interact in an ecosystem?
5. Would you expect to find the same kinds of interactions between organisms in very different ecosystems? Why or why not?
6. Why is it important to understand feeding relationships in an ecosystem?
Answers
Examples of nonliving things in an ecosystem include sunlight, water, air, rocks, soil, and minerals.
Factors that could affect the number of organisms in an ecosystem include the availability of food and water, temperature, weather conditions, availability of shelter or habitats, the presence of predators and disease, and human activities such as deforestation or pollution.
Organisms interact in an ecosystem to obtain resources such as food, water, shelter, and mates, and to avoid being eaten by predators or infected by diseases. Some organisms also form mutualistic relationships, where both parties benefit from the interaction.
Different ecosystems can have different organisms and interactions based on the unique features of each ecosystem, such as climate, geography, and available resources.
Understanding feeding relationships in an ecosystem is important because it helps us understand the flow of energy and nutrients through the ecosystem. This knowledge can inform conservation efforts and help us manage and protect ecosystems for the benefit of all living organisms, including humans.
Answer:
1. An ecosystem is a system of interactions between living and nonliving things in a particular environment.
2. Some examples of nonliving things in an ecosystem include sunlight, soil, rocks, air, water, and temperature.
3. Factors that could affect the number of organisms in an ecosystem include availability of resources, predation, competition, and environmental changes.
4. Organisms interact in an ecosystem in order to find food, to find mates, to escape predators, and to compete for resources.
5. No, you would not expect to find the same kinds of interactions between organisms in very different ecosystems due to differences in biotic and abiotic factors.
6. It is important to understand feeding relationships in an ecosystem because understanding these relationships gives us insight into the stability, dynamics, and functioning of the overall ecosystem. It can also provide an understanding of how the ecosystem may respond to environmental changes.

describe the cellular evidence that both plant and animal cells obtain energy through cellular respiration.
Answers
Answer:
Explanation:
The glucose required for cellular respiration is produced by plants. Plants go through a process known as photosynthesis. Photosynthesis can be thought of as the opposite process of cellular respiration. Through two processes known as the light reactions and the dark reactions, plants have the ability to absorb and utilize the energy in sunlight. This energy is then converted along with water and carbon dioxide from the atmosphere into glucose and oxygen. Since this is the opposite process of cellular respiration, plants and animals are said to have a symbiotic relationship. This means that plants and animals live together and benefit from each other.

Answers
Answer:
The illustration of anaphase stage of mitosis is where the spindle fibers start to pull away from the center of the cell.
MITOSIS:
Mitosis is the process whereby a single cell results in two daughter cells that are genetically identical to one another.
Mitotic division occurs in stages namely: prophase, metaphase, anaphase and telophase.
Prophase: Condensation of chromatids to more visible X-shaped structure called chromosomes.
Metaphase: Chromosomes line up at the cell's equator
Anaphase: Chromosomes are pulled apart by the spindle fibers that attached to their centromere.
Telophase: Reformation of the nuclear membrane.
According to this question, in the anaphase stage, spindle fibers start to pull away from the center of the cell to separate the chromosomes.

How do auxins cause plants to bend?
A) Auxins make plant cells grow larger towards the light causing it to bend.
B) Auxins make plant cells grow heavier causing it to tip on one side.
C) Auxins cause plants to grow wider.
D) Auxins cause plant cells to shrink on one side making it less heavy, which tips the plant on the other side.
Answers
Answer:A) Auxins make plant cells grow larger towards the light causing it to bend.
Answer:
A.
Auxins make plant cells grow larger towards the light causing it to bend.
Explanation:
The auxins go more in the shady side, and that is why there are more auxins in the shady side, but in the illuminated side, there are less auxins. That will cause a bend in the growth of the plant towards the light source because the shady side has more auxins to make it grow. This is the reason why when there are auxins in a plant, they start to grow towards light.

Three Anacharis plants were placed inside inverted test tubes filled with water. One test tube was exposed to low light, another to medium light while another was exposed to high light. The table provided shows the results of this experiment. Notice that more oxygen was produced by the Anacharis in high light.
Based on the information provided, what is the difference in volume (in mL) of oxygen produced between the low light and high light plants after 45 minutes? Record your answer below
Answer value
Answers
Answer:
Anacharis in High Light produces more mLof oxygen per min than Anacharis in Low Light Anacharis and in Medium Light.
Explanation:
The increased light intensity also increases the rate of photosynthetic activity. As photosynthesis occurs, the energy from sunlight, along with CO2 is converted to chemical energy in the form of glucose.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
or Carbon dioxide + water = energy (glucose) + oxygen
Photosynthesizing cells in green plants produce oxygen as a waste product. As this process is rate-limited, certain factors may increase the reaction rate. These include:
carbon dioxide concentration
water availability
ambient temperature
light intensity;
