Answer:
A large community of plants and animals in a major habitat, such as a desert or a forest. Abiotic factors, such as rain, temperature and sun affect the biome drastically. If there is more rain, there will likely be more plants and animals able to live in that area. If it is hotter and sunnier, less plants and animals will be able to live in the area. Biotic factors, such as beavers in a forest can also change the biodiversity of the area. Beavers create dams which slow the movement of water. This allows other animals that can't swim against strong currents to live in the ponds and lakes the beavers make. This would be impossible if the beavers weren't there.

Explanation:
33. Assertion : Egestion in amoeba takes place through a
permanent membrane present in them.
Reason : Cilia is absent in amoeba.
(a) Both Assertion and Reason are true and Reason
is the correct explanation of Assertion.
(b) Both Assertion and Reason are true but Reason is
not the correct explanation of Assertion.
(c) Assertion is true but Reason is false.
(d) Both Assertion and Reason are false.
Both the statement and the reason are true, but the reason is not the correct explanation of the statement, as shown in option B.
We can arrive at this answer because:
The amoeba is a unicellular organism that assumes a gelatinous composition and without the presence of cilia or flagellum, which are a kind of hair present in the movement.Despite being an organism with a simple composition, the amoeba feeds through Egestion, when it includes other organisms or elements in its structure.Egestion takes place through the permanent membrane that surrounds the amoeba's body.This membrane has pseudopods that encompass the organism to be absorbed until it forms a kind of food vessel.This process has nothing to do with the absence of cilia.

https://brainly.com/question/24592455?referrer=searchResults
The assertion regarding egestion in Amoeba is correct. The membrane present in the body helps in egesting the waste out of the body.
In the absence of cilia, the membrane acts as a passage for egestion.Both the assertion and the reason are true in this case. But, the reason is not the correct explanation for the assertion as it does not directly support the assertion. Hence, the correct option is (b) Both Assertion and Reason are true but Reason is not the correct explanation of Assertion. In summary, the assertion and reason both were true in the given statement. The membrane present in Amoeba helps in egesting waste from the body. The reason provided about the absence of cilia does not provide a direct explanation of the assertion. Hence, the option (b) Both Assertion and Reason are true but Reason is not the correct explanation of Assertion is the correct option.

A field contains 700 kg of plant material. How many kilograms of tertiary consumers could be supported
Answer:
Explanation:
700kg +120= 820
In this field, the area would support 700kg of primary consumers, 70 kg of secondary consumers, and 7.5 of tertiary consumers.
What are tertiary consumers?Producers utilize the energy from the sun to build basic organic molecules that they consume as food through a process known as photosynthesis.
An animal that consumes both main and secondary consumers for sustenance is referred to as a tertiary consumer.
Tertiary consumers are often carnivorous predators, although they can also be omnivores or creatures that eat both meat and plants.
Therefore if the field contains 700kg of primary consumers, 70 kg of secondary consumers, and 7.5 of tertiary consumers, loss of energy at each level.

explain how cholinergic synapse functions
Answer:
Cholinergic synapses are miniature transducers that convert an electrical signal from the presynaptic nerve endings into a chemical signal (acetylcholine), which then diffuses across the synaptic cleft and triggers an electrical signal on the postsynaptic side by interacting with the same type of receptors that were used to generate the electrical signal on the presynaptic side.
Explanation:
Hope it helps:)
The Cholinergic synapses functioned by converting the presynaptic electrical signal into a chemical signal.
The Cholinergic synapses refers to the miniature transducers which can convert the electrical signal from the presynaptic nerve endings into a chemical signal (acetylcholine)
The conversion does lead to a diffuse across the synaptic cleft and triggers the electrical signal on the postsynaptic side by interacting with the same type of receptors that were used to generate the electrical signal on the presynaptic side.In conclusion, the Cholinergic synapses functioned by converting the presynaptic electrical signal into a chemical signal.

Based on the graphs shown, what would you conclude about the conditions under which enzymes function in cells?
Enzymes only function at a specific pH and temperature and cannot function over a range of pH or temperature.
Enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature.
Enzymes do not have a specific pH or temperature at which they are most effective but function optimally over a range of pH and temperature.
Enzymes work equally well at the low and high ends of their temperature range, but reaction rate drops quickly at the high end of their pH range.
Based on the graphs shown, it is possible to conclude that enzymes are most effective at a particular pH and temperature but can function over a range of pH and temperature. Enzymes speed up chemical reactions.
Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy of these reactions.
An enzyme works more efficiently at optimum pH and temperature values, which are specific for each enzyme.
Enzymes are denatured by extreme pH and temperature values because out-of-range values break down the hydrogen bonds that form the tertiary structure of the enzyme.

Pharyngeal slits are present in the embryo stage of fish, amphibians, reptiles, birds, and mammals. These homo-logous structures are present in the embryos of evolutionarily related organisms.
Homologous structures are similar phenotypic traits in organisms that share a common ancestor, these features may or not have the same function.
Conversely, analogous structures are phenotypic traits that have the same function in unrelated organisms.
A well-known example of homo-logous structures is the limbs of cats, humans and dolphins.
Embryonic homologies are homo-logous structures observed prior to adulthood, which can be used as pieces of evidence that indicate a common evolutionary origin.
