Explanation:

The cardiovascular and lymphatic systems transport fluids throughout the body and help sense both solute and water levels and regulate pressure. If the water level gets too high, the urinary system produces more dilute urine (urine with a higher water content) to help eliminate the excess water.

Answer:

The receptor and afferent pathway are pathways that help the body stay n homeostasis. An example of the receptor is like temperatures in your skin. An example of Afferent pathways are sensory neutrons.

Explanation:

the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .

plz mark my answer as brainlist plzzzz.

hope this will be helpful to you .

When the pH is raised from 2 to 11 the most likely effect on the reaction is ;  

The rate of reaction will decrease/delayed

Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.

Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.

Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.

Answer:

My answer is the genotypes are BB, Bb, Bb, and bb.

Explanation:

I attached a photo of the punnet square after crossing the genotypes Bb and Bb.  Crossing the B on top with the B on the side results in the genotype BB.  Crossing the b on top with the B on the side results in Bb.  The genotype that results is written in the box that connects the row and the column (such as top row and left column results in BB).  

Answer:

The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.

Answer:

1/8 or 12.5%

Explanation:

This question involves two genes coding for height and flower color in pea plant. The alleles for tallness (T) and red flowers (R) are dominant over the alleles of short (t) and white flowers (r).

According to this question, a tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr). The following gametes is produced by each parent:

TtRr - TR, Tr, tR and tr

Ttrr - Tr, Tr, tr and TR

Using these gametes in a punnet square (see attached image), the following proportion of F1 offsprings will be produced as follows:

Tall, Red (T_R_) = 6

Tall, white (T_rr) = 6

Dwarf, red (ttR_) = 2

Dwarf, white (ttrr) = 2

The probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

Margaret can have all her children with attached earlobes only if she marry a man with AA dominant genotype.

As given,

Margaret has detached earlobes (a) which is a recessive trait  If she wanted all of her children to have attached ears (A) if she have to marry a man with the dominant trait

Punnett' square:

                                    A           A

                        a       Aa         Aa  

                          a       Aa         Aa

[Aa] are the genotype with attached earlobes [dominant genotype]

Therefore, Margaret can have all her children with attached earlobes only if she marry a man with AA dominant genotype.

Answer:

Symbiosis is when one creature benefits while the other is unaffected. Parasitism is when one creature benefits while the other is harmed.

Explanation:

Think of parasites. They feed off of other creatures and harm them in the process. Symbiosis is similar, but neither creature is harmed.

Explanation:

in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.

Answer:

An amino acid.

Explanation:

Each codon applies to an individual amino acid.

Answer:

Each codon corresponds to a single amino acid (or stop signal), and the full set of codons is called the genetic code. The genetic code includes 64 possible permutations, or combinations, of three-letter nucleotide sequences that can be made from the four nucleotides.

Answer:

2 offspring will have the genotype Bb.  

Explanation:

Crossing the genotypes Bb and Bb results in 2, or 50% of the offspring having the genotype Bb.  In the top right box, the B on the top and the B on the side make the BB genotype.  In the top left box, B and b make the first Bb genotype.  The lower right box crosses B and b to make the second Bb genotype.  The last box in the bottom right crosses b and b, resulting in the genotype bb.  So, after crossing the genotypes written on the top and side of the punnet square, 2 of the offspring will have the Bb genotype.  (I got this by combining the letters outside the punnet square in the box where the row and column meet) .
