A large protein that passes through the nuclear pore must have an appropriate A)sorting sequence, which typically contains the positively charged amino acids lysine and arginine. B)sorting sequence, which typically contains the hydrophobic amino acids leucine and isoleucine. C)sequence to interact with the nuclear fibrils. D)Ran-interacting protein domain. Multiple Choice
Answer:
A)sorting sequence, which typically contains the positively charged amino acids lysine and arginine.
Explanation:
Protein sorting refers to the cellular process by which proteins are transported to their corresponding localizations both inside or outside the cell. A nuclear localization sequence (NLS) is a short amino acid signaling sequence that is able to mediate the transport of proteins into the nucleus. The proteins that are 'tagged' by an NLS sequence can pass through the nuclear envelope via nuclear pores. This sequence (NLS) is typically composed of protein motifs consisting of positively charged lysine (Lys) and arginine (Arg) amino acid residues, which are exposed on the protein surface. In consequence, the NLS sequence is recognized by the importin α/β heterodimer receptor, which transports the NLS-tagged protein into the nucleus. It has been shown that the deletion of the NLS sequence disrupts nuclear import, whereas the fusion of non-nuclear proteins with NLS sequences represents a useful strategy to introduce proteins into the nucleus.

Cell specialization is important during the growth and development of
a multicellular organism. This process is most directly regulated by
Answer:
Protein
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms.
Cell specialization is also referred to as cell differentiation and it can be defined as a biological process through which generic cells transform into specific cell types, so as to enable them perform certain functions within the body of a living organism.
Simply stated, it's the special function or job in the body of a living organism that are associated with cells.
Generally, cell specialization plays a significant role in the development of embryos.
Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell specialization is fundamental and key for the growth and development of a multicellular organism.
Furthermore, cell specialization as a process is most directly regulated by protein; one super regulating protein encourages cell differentiation while the other tries to stop or prevent the process. These proteins are referred to as master regulating proteins or Helix-Loop-Helix proteins.

The Krebs cycle is a series of chemical reactions that: Group of answer choices Metabolize acetyl-CoA and produce ATP, carbon dioxide, and hydrogen ions Metabolize lactate and produces pyruvate, ATP, and hydrogen ions Metabolizes water and produces ATP and hydrogen ions Metabolizes alcohol and produces ATP and water in the mitochondria Breaks fatty acids into two-carbon molecules
Answer:
Metabolize acetyl-CoA and produce ATP, carbon dioxide, and hydrogen ions.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in the cells of living organisms, so as to produce energy in the form of adenosine triphosphate (ATP).
During cellular respiration, high energy intermediates are created which are then oxidized to make adenosine triphosphate (ATP). Also, the high energy intermediary products are produced at the glycolysis and citric acid cycle stage.
Glycolysis can be defined as a biological process that uses the energy released and stored during the Krebs cycle to form adenosine triphosphate (ATP). Thus, glycolysis is a series of chemical reactions that is typically used to break glucose into pyruvic acid.
Krebs cycle is also referred to as the citric acid cycle (TCA cycle) and it can be defined as a series of enzyme-catalyzed reactions used to release stored energy in most living organisms by metabolizing (oxidation) acetyl-CoA which are typically derived from proteins, carbohydrates, and fats.
This ultimately implies that, the Krebs cycle is a series of chemical reactions that metabolize acetyl-CoA and produce adenosine triphosphate (ATP), carbon dioxide, and hydrogen ions.
14). Clonal selection and differentiation of B cells activated by antigen exposure leads to the production of ________. A) large quantities of the antigen initially recognized B) vast numbers of B cells with random antigen-recognition receptors C) long-lived erythrocytes that can later secrete antibodies for the antigen D) short-lived plasma cells that secrete antibodies for the antigen
Answer:
The correct answer is D) short-lived plasma cells that secrete antibodies for the antigen
Explanation:
Each B lymphocyte has an antigen receptor (BCR: B cell receptor), a surface immunoglobulin (IgM or IgD), that binds to specific domains of the antigen called antigenic determinants or epitopes. Only B lymphocytes with a high antibody affinity for the antigen, and which are capable of processing and presenting it, will be positively selected. In this contact between the two cells, an exchange of chemical signals takes place that leads to the activation, clonal proliferation and differentiation of B cells into two sister subclones: one of antibody-secreting plasma cells, and the other of memory primed B cells. Therefore, only these last positively selected B lymphocytes will survive, proliferate and differentiate into plasma cells, synthesizing and secreting antibodies of a single isotypic class, with a unique specificity and high affinity, improving the ability to adhere to the antigen and, thus , neutralize and destroy pathogens.

What is an ecological niche?
An ecological niche is the particular habitat of a particular species in an ecosystem. The term was coined by Joseph Grinnell in 1917. The selection of a niche depends on the environmental condition, to avoid competition and availability of the food. The different types of niches are spatial niches, tropical niches, and hypervolume niches.
Habitat is defined as the coexistence of abiotic and biotic things. Examples of habitats are the ocean and forests. A niche whereas is an inclusive space occupied by species in a habitat.
The ecological niche is occupied by a species of organism to avoid competition.

What is the most likely effect of freshwater pollution?
O A. Polluted groundwater lowers the porosity of the zone of
saturation.
O B. Invasive plants develop resistance to overused herbicides.
O C. Soil becomes contaminated, causing invasive plant species to
crowd out local species.
O D. Groundwater becomes overused, lowering the water table.
Answer:
c
Maybe this...
I think
The most likely effect of freshwater pollution is Soil becomes contaminated, causing invasive plant species to crowd out local species. Option C is correct.
Polluted groundwater can seep into the soil, contaminating it with harmful chemicals. These chemicals can then make their way into the food chain, harming both plants and animals. Invasive plant species are those that are not native to an area and can outcompete native species for resources. When soil is contaminated, it can create an environment that is more favorable for invasive plant species, which can then crowd out local species.
Polluted groundwater lowering the porosity of the zone of saturation, is not a direct effect of pollution. Invasive plants developing resistance to overused herbicides, is more likely to be caused by overuse of herbicides, not pollution. Groundwater becoming overused, lowering the water table, is a possible effect of pollution, but it is less likely than soil contamination. Option C is correct.

what are the cells that pass from parents to their children
Answer:
Genes are the blueprint for our bodies. If a gene contains a change, it disrupts the gene message. Changes in genes can cause a wide range of conditions. Sometimes a changed gene is inherited, which means it is passed on from parent to child. Changes in genes can also occur spontaneously.
Nitrogen is the most common element in the air. Why do bacteria play a role in the nitrogen cycle?
Explanation:
Bacteria play a role in the nitrogen cycle because:The bacteria’s helps in breaking down the organic materials which has nitrogen in it, and helps in giving the nitrogen back to the cycle. Bacteria helps in breaking down of the leaves and then it diffuses the nitrogen to the soil. Prokaryotes also plays an important role in the nitrogen cycle. The nitrogen fixing bacteria present in the root zone of plants basically in the soil, helps in conversion of the nitrogen into ammonia. Then the nitrifying bacteria converts the ammonia to the nitrites or can say nitrates.
