Answer:

Eukaryotes have a nucleus.

Answer: Polygenic recessive

Explanation: Because polygenic dominance describes a relationship between the alleles of a polygenic trait where some alleles are dominant and others are recessive.

This is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

Polygenic inheritance can be described as the inheritance of traits that are governed by different genes and not just a single gene, and can also be referred to as non-Mendelian inheritance, where traits run like a bell. distributes the sizes and shows the different combinations such as dominant and recessive alleles.

Polygenic traits express several different phenotypes, or displayed characteristics where this inheritance is a type of incomplete dominance inheritance, where the expressed phenotype is a mixture of inherited traits.

Thus, this is the pattern of inheritance of Polygenic recessive. So, the correct option is (D).

How would an increase in surface temperatures in the pacific affect sea otters and why would this happen?

The water that sea otters live in is chilly, ranging from 35 to 60 degrees Fahrenheit—much too cold for humans. Otters don't have blubber to keep them warm like other marine mammals. Instead, they rely on their thick fur coat to maintain a constant body temperature of 100 degrees Fahrenheit.

Explanation:

Human immunodeficiency virus type 1 (HIV-1) enters target cells by first binding to the primary receptor CD4 and then to a coreceptor, generally one of the chemokine receptors CCR5 and CXCR4 (4). CD4 binding induces structural changes in the envelope (Env) glycoprotein that form and expose the coreceptor binding site. There are two main interactions between Env and coreceptor (13, 14, 25, 50, 51): the base of the third variable loop (V3) engages the N terminus of the coreceptor, while the crown of the V3 loop that includes the highly conserved GPGR/Q arch motif binds to the extracellular loops of the coreceptor, with the second extracellular loop of the coreceptor being particularly important (16, 25, 35, 48, 62). Although some HIV-1 strains are able to use a variety of different G protein-coupled receptors to gain entry into CD4+ cell lines, the great majority of these viruses use CCR5 and/or CXCR4 as coreceptors to infect primary cells (3, 4, 10, 23, 47, 66). CCR3, GPR15, APJ, and FPRL-1 are among the most frequently used alternative coreceptors when overexpressed on cell lines (11, 26, 43, 47, 57). Rare cases of HIV-1 strains that are able to use FPRL-1 and GPR1, but not CCR5 or CXCR4, have been reported (57); however, their in vivo relevance remains unknown.

To characterize the biological processes underlying HIV/simian immunodeficiency virus (SIV) transmission, we recently developed an experimental strategy that permits the identification, enumeration, and molecular cloning of transmitted/founder (T/F) viruses (28, 53). This strategy, which employs single-genome amplification (SGA) and direct amplicon sequencing of HIV/SIV RNA or DNA from the plasma or infected cells, makes it possible to infer the nucleotide sequence of the viral strain(s) that initiated productive infection weeks earlier (1, 28, 29, 37, 53, 58, 67). An important prediction of this approach has been that inferred T/F viruses are fully functional and encode all proteins necessary to establish a new infection. Indeed, this prediction has been borne out in numerous studies, which have shown that T/F viral genes as well as full-length genomes are biologically active. Sets of T/F Envs have been shown to mediate efficient virus entry in single-round infection assays, and they invariably use CCR5 as a coreceptor (28, 34). Similarly, T/F infectious molecular clones (IMCs) of HIV-1, SIVmac and SIVagm all produce replication competent virus that grow to high titers in primary CD4+ T cells (22, 38, 54).

MATERIALS AND METHODS

Amplification of the HIV-1 env gene. Serial plasma samples collected from an acutely infected plasma donor, ZP6248, were purchased from ZeptoMetrix. A total of seven plasma samples were collected between 12 February and 9 March 1997, and viral loads (VLs) were determined by the COBAS Amplicor HIV-1 monitor test.

Sequence analysis. All SGA amplicons were sequenced directly by cycle sequencing and dye terminator methods using an ABI 3730xl genetic analyzer (Applied Biosystems, Foster City, CA). Individual sequences were assembled and edited using the Sequencher program 4.7 (Gene Codes, Ann Arbor, MI). The env sequences were aligned using CLUSTAL W (60), and manual adjustment for optimal alignment was done using MASE (20).

Answer: the 1st one

Explanation:

A grassland predator and prey, such as a cheetah and a zebra. Therefore correct option is (A).

The pair of organisms that is most likely to have adaptations in common is a pair of organisms that share similar environmental pressures or ecological niches. Organisms that occupy similar habitats, have similar diets, or face similar challenges are more likely to evolve similar adaptations over time.

For example, predatory animals such as lions, tigers, and leopards have evolved similar adaptations such as sharp claws, powerful jaws, and keen senses to help them catch prey. Similarly, desert-dwelling animals such as camels, kangaroo rats, and fennec foxes have adaptations such as the ability to conserve water, tolerate heat, and dig burrows in sandy soil to survive in their arid environments.

Answer:

Explanation:

The rate limiting reaction of aerobic respiration involves the phosphorylation of fructose phosphate by the enzyme phosphofructokinase. The rate at which this enzyme makes product is [increased, decreased] when ATP levels rise because the molecule ATP binds to an allosteric site on the enzyme and acts as a direct inhibitor. When ATP levels fall AMP binds to the allosteric site of phosphofructokinase. This interaction leads to an increase of cellular ATP, so that this is an example of a negative feedback loop.

An aerobic respiration can be defined as a chemical and biological process that involves the use of oxygen in living organisms to make energy (ATP) from carbohydrates (sugars) during cellular respiration.

This ultimately implies that, an aerobic respiration can take place or occur in the presence of oxygen.

An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction, especially by lowering the activation energy of its chemical reactants.

There are four (4) main factors that affect the actions and the rate of an enzyme and these include the following:

We have that the right behavior of the cell in a situation where excess water enters the cell is

Cells swell as water moves into them.

Option A

Generally Water is Good for the body, But excess of water has its own adverse effect .

Sodium wash away in the blood causes hypo tonic solution in comparison to blood cell.

Therefore, on the count of excess water entering into to the blood cells, the cells tends to rise or swell as water enters into them.

Cells swell as water moves into them.

Answer:

The substrate molecules are entering the cells, so no product is made yet.

There is sufficient substrate, so the reaction is proceeding at a maximum rate

As the substrate is used up, the rate decreases (the slope is less steep)

The line is flat because no new substrate remains and thus no new product appears

Explanation:

First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.
