Answer:
From eating things
Explanation:
Depending on where they are in the food chain, one animal eats a plant (absorbing it's energy), the next animal eats that animal(absorbing its energy)...etc.
4 Select the correct answer. A family has a Y-linked disease that affects the father. What is the chance of a male offspring inh А. 100% OB. 50% Oc. 25% OD. 0% Reset Next
Answer:
Remember that males have an x and y chromosome, while women have two x chromosomes.
Explanation:
This means that a female offspring (daughter) inherits her father's only x chromosome and one of her mother's x chromosomes, while a male will receive his father's y chromosome and one of his mother's x chromosomes.
This means that the boy will necessarily inherit his dad's Y chromosome, and any diseases that it carries.
The chance of a male offspring inheriting the disease is
A) 100%
Answer:
Mother
Explanation:
This mutation needs two X chromosomes. Only the mother has two X chromosomes (XX). The father is male, so he only had one X chromosome (XY).

What happens after activation of T cells
Answer:
Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells.
Explanation:
Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.
Do producers in an ecosystem transfer all their energy to first-level consumers?
Answer:
Producers in an ecosystem transfer all their energy to primary-level consumers. Organisms at higher trophic levels tend to be fewer in number than those at lower trophic levels. ... The lowest trophic level of any ecosystem is the producers.

In a normal cellular protein, where would you expect to find a hydrophobic amino acid like valine?
A.In the interior of the folded protein, away from water.
B.On the exterior surface of the protein, interacting with water.
C.In the transmembrane portion interacting with lipid fatty acid chains.
D.In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
E. Anywhere in the protein, with equal probability.
Answer:
D. In the interior of the folded protein, away from water, or in a transmembrane portion interacting with lipid fatty acid chains.
In a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).
Aminoacids can contain hydrophilic side chains that interact with water molecules or hydrophobic side chains that cannot make hydrogen bonds and therefore do not interact with water.
In membrane protein, hydrophilic amino acids are arranged so they can interact with water on the surface of the cell membrane,
Moreover, hydrophobic amino acids of membrane proteins are arranged away from water so they can interact with fatty acid chains in the transmembrane portion of transmembrane proteins or with other hydrophobic amino acids in the interior of the folded protein.
In conclusion, in a normal protein, it is expected to find valine in the interior of the folded protein, away from water, or in a transmembrane portion, interacting with lipid fatty acid chains (Option D).

What structure of nerve cells (neurons)
allows for communication throughout the
body?
Answer:
While neurons have a lot in common with other types of cells, they're structurally and functionally unique. Specialized projections called axons allow neurons to transmit electrical and chemical signals to other cells. Neurons can also receive these signals via rootlike extensions known as dendrites.

Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.

Some people cannot digest milk products because they lack an enzyme to break down lactose in milk.
Which enzyme is it?
A. hydroxylase
C. maltase
B. Lactase
D. peroxisomes
Answer:
Lactase
Explanation:
DNA polymerase has multiple mechanisms for editing and error correction whereas the capacity for error correction in RNA polymerases seems to be quite limited. However, like DNA mutation, an RNA polymerase error in transcription can cause production of a mutated protein. The limited error correction of RNA polymerase seems to be inconsistent with the potential serious consequence of producing a protein with an altered amino acid sequence. Select three reasons that explain why error correction is not as necessary in RNA polymerases as it is in DNA polymerases.
The given question is incomplete as the option are not provided however, the correct options are as follows:
Defective proteins are often degraded quickly, making their effects temporary.
Single amino acid substitutions caused by errors in mRNA transcription would not affect protein function.
Unlike DNA mutations, mRNA transcripts have short half-lives and are not inherited across many generations.
Degradation of defective proteins activates mRNA repair pathways RNA polymerases synthesize many transcripts per gene, so only a small fraction of RNA transcripts would have errors.
ch mRNA molecule is only translated once and then degraded
Answer:
The correct answer is - statements 1, 3, and 4.
Explanation:
DNA polymerase is the enzyme that is responsible for the production of the new DNA molecule and any mutation in this enzyme that will inhibit the DNA repair process which affects future generations.
RNA polymerase is an enzyme that is responsible for the transcription of DNA to mRNA and any error-prone mRNAs have chances of degradation. Error in DNA replication is from generation to generation as it is inherited
The process of transcription is quick.

Middle Class
Working Class
According to Gilbert-Kahl Model, they distributed the population based on constituents like power, wealth, wisdom and influence.
Their six-class model includes capital class, the upper and middle class, working, working poor, and the underclass.
The correct answer is:
Option A. Lower class.
The explanation for this is:
According to this American arrangement, the individuals or the community were ranked based on different social levels and statuses.The lower class is a group of people and community who are generally jobless and labourers. The lower class lacks earnings, literacy and skills.Therefore, the lower class is not a strata in Gilbert Kahl model of the American Class System.
