Which abiotic factor most likely controls where the plants live in this environment ?

Oxygen levels for aquatic animals

Oxygen from the air and oxygen produced by aquatic plants dissolves in water. Without this, aquatic animals would suffocate and die. Healthy lakes and rivers have high levels of oxygen, and polluted waters often have low levels of oxygen. This pollution means that only certain species can survive there such as sludgeworms. These are bioindicator species because their presence or absence informs us about the condition of the habitat.

Carbon dioxide levels for plants

Carbon dioxide is a reactant in photosynthesis which means plants need it to survive. Areas with higher levels of carbon dioxide are more likely to have healthy plants growing. Farmers often release carbon dioxide within their greenhouses to maximise their crop yield. Woodlands often have higher carbon dioxide levels than open grassland, so many plants living in open areas have evolved mechanisms to overcome a shortage of carbon dioxide.

Answer:

A. Globular protein

Explanation:

Globular protein e.g., haemoglobin are spherical shaped proteins that are compact. They have an irregular protein sequence shape and highly folded due to presence and interactions with amino acid groups.

Which of these is an example of chemoprevention?

expeople1 [14]

Answer: A. Research into a phytochemical from a plant which might inhibit cancer development.

Explanation:

The chemoprevention is a process of utilization of chemical formulations such as medication, supplements and vitamins to the stop the growth of cancer cells. This is necessary and important for people which are at high risk of developing cancer.

The research for the phytochemical derived from the plants can be an example of chemoprevention as this will help in inhibiting the cancer development.

If the population of hawks in this area increases, their prey populations might decrease. Later, with fewer prey, the hawk popul

Vanyuwa [196]

Answer:

This question lacks options, the options are:

1. an ecosystem completely out of balance

2. how ecosystems maintain stability over time

3. interaction between biotic and abiotic factors within an ecosystem

4. ecological succession

The answer is 2

Explanation:

An ecosystem comprises of biotic organisms, abiotic substances etc. that interact with one another. The biotic components of an ecosystem are known to feed on one another in order to obtain energy. However, stability of an ecosystem must be maintained between predators and prey or else there will be extinction of many species of organisms.

One way balance in an ecosystem is maintained over time is by the increase and decrease in population of predators and preys in an ecosystem. For example, If the population of hawks (predator) in an area increases, their prey populations might decrease because there will be less predation.

Also, at a later time, when there is a fewer population of prey, the hawk population might decrease because there is less food to eat. The prey populations might then increase.

steroid hormones are lipophilic. this allows steroid hormones to . steroid hormones are lipophilic. this allows steroid hormones

Rudik [331]

According to the research, the correct option is They bind to intracellular receptors. Steroid hormones are lipophilic this allows steroid hormones to bind to intracellular receptors.

<h3>What are Steroid hormones?</h3>

They are lipids with a polycyclic structure from which different compounds are derived that are relevant to biology and interact with intracellular nuclear receptors.

Steroids are lipophilic hormones that are found in nature and can easily enter the cell, cross the cytoplasm and reach the nucleus, exerting their action by binding to intracellular receptors, although they can also be synthesized in laboratories.

Therefore, we can conclude that according to the research, the correct option is They bind to intracellular receptors. Steroid hormones are lipophilic this allows steroid hormones to bind to intracellular receptors.
