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.

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.
More information:
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.

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.

which sequence accurately describes the path traveled by a new protein from when it first starts to be translated to its release from the cell?
The sequential pathway of a protein from it first starts to be translated to its release from the cell is cytosol > ER > Golgi > vesicle > plasma membrane > external environment. These proteins are synthesized in the ribosomes.
The exported proteins are synthesized (i.e., translated) in the ribosomes of the cytosol that bound to the endoplasmic reticulum in order to enter into the endomembrane system.
Subsequently, extracellular proteins undergo processing in the Golgi apparatus, which is connected to the rough RE by transport vesicles.
Finally, these proteins pass through transport vesicles in order to be exported from the cell by endocytosis.
