Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which saves water.
Nitrogenous waste in the body tend to form toxic ammonia, which must be excreted. Mammals such as human excrete urea, while birds, reptiles, and some terrestrial invertebrates produce uric acid as waste in the form of a white paste or power. The production of uric acid involves a complex metabolic pathway that is energetically costly in comparison to processing of other nitrogenous wastes such as urea or ammonia, it has the advantages of reducing water loss and, hence, reducing the need for water.

Answer:

In a cross of a homozygous prevailing (AA) individual and a homozygous recessive(AA) person,

a. on the off chance that they have a kid, what is the likelihood that the kid will be heterozygous?

If you cross somebody who is homozygous predominant with one who is homozygous latent, the entirety of the posterity will be heterozygous (AA). Accordingly, there is a 100% possibility of delivering a posterity that is heterozygous.

b. what is the likelihood that the youngster will be homozygous latent?

There is no way of creating a kid that is homozygous passive. The entirety of the posterity will be heterozygous. In this way, the likelihood is zero.

c. in the event that they have two kids, what is the likelihood of the first being homozygous prevailing and the second being homozygous passive?

Again, this can't be determined, on the grounds that there is zero chance of delivering a posterity that is homozygous prevailing or homozygous passive. The likelihood is zero. In any case, for no reason in particular, suppose that the punnet square uncovered that there was 1/4 possibility of creating a kid that is homozygous passive. To decide the likelihood that the subsequent youngster will likewise be homozygous passive, you complete this straightforward duplication:

1/4 x 1/4 = 1/16

In this manner, there would be a 1/16 possibility of the subsequent kid being homozygous passive. In the event that you needed to discover the likelihood of the third kid being homozygous passive, you would do the accompanying:

1/4 x 1/4 x 1/4 = 1/64

Thus, there would be a 1/64 possibility of the third kid being homozygous latent. Once more, I was simply giving in model, yet it doesn't have any significant bearing right now, the entirety of the posterity will be heterozygous.

Another question...A latent allele on the X chromosome is answerable for red-green visual weakness in people. A typical lady whose father is visually challenged weds a partially blind man. What is the likelihood that this couples child will be visually challenged?

XX = female

XY = male

Let C = typical vision (predominant)

Let c = red-green visual weakness (latent)

A typical lady what father's identity is' partially blind must be a transporter, or heterozygous. This implies she acquired the ordinary allele from her mom and the visually challenged allele from her dad.

Genotypes:

Ordinary lady - Xc

Partially blind man - Xc Y

On the off chance that these two mate, here are the accompanying prospects:

half of the female posterity will be bearers with ordinary vision (Xc)

half of the female posterity will be homozygous passive and partially blind (Xc)

half of the male posterity will have typical vision (XC Y)

half of the male posterity will be visually challenged (Xc Y)

In this manner, the likelihood that the couple's child will be partially blind is half, or 1/2.

Sheryl addressed this Was this answer accommodating?

XX= lady, XY=man

Alleles:

XC=normal; Xc=colorblind

Typical Genotypes:

XC (typical lady)

Xc (typical lady, yet bearer)

Xc (visually challenged lady)

XC Y (typical man)

Xc Y (visually challenged man)

Lady has typical vision, yet her dad is visually challenged. In this way, she needed to get XC from her mother (must have one, she's ordinary) and Xc from her father (it was everything he could give her): Xc

Man is visually challenged: Xc Y

Xc Y

XC Y

Xc Y

Which statement gives an example of how the use of resources has changed?

Brums [2.3K]

Answer:

Option D. Car companies have developed hybrid cars.

Explanation:

Nowadays car companies have developed hybrid cars. In hybrid cars, the cars are moved by using electric energy instead of fossil fuels. Hybrid cars uses batteries which can be charged by electricity and this store electricity is used to run cars. These types of cars reduce carbondioxide emissions and decrease occurs in air pollution.

For a science fair project, two students decided to repeat the Hershey and Chase experiment, with modifications. They decided to

Reptile [31]

Answer: E. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.

Explanation:

The Hershey-Chase experiment, is an experiment that demonstrated that the genetic material of phage isn't protein but rather it's DNA.

Based on the information given in the question, the experiment will not work because amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.

Therefore, the correct option is E.

In the evolutionary adaptation sense, what is fitness?

Stells [14]

The answer is letter A.
<span>
In the evolutionary sense fitness refers to the measure of reproductive success of an individual or of organisms in general. Those organisms that leave the largest number of mature offspring are the fittest. Fitness can be achieved through survival or mortality selection, mating success or sexual selection, and family size or fecundity selection. Fitness is critical for a species’ survival and is a major adaptation that all organisms do through a long period of time. <span> </span></span>
