Assume all are homozygous. Alleles: A=agouti, C=chinchilla, a=albino, A is dominant over C and a, C is dominant over a.
Luden [163]

Answer:

The punnet square can be completed as follows:

       C        C

A    AC       AC

A    AC       AC

The results from the punnet square show that all of the offsprings form will be agouti as agouti is the dominant trait. However, the genotype of the offspring will be heterozygous carrying the alleles AC.

A dominant trait is the trait which arises due to a dominant allele. The dominant allele masks the effect of the recessive allele.

A heterozygous genotype occurs when the alleles of a gene are different.

The afferent arteriole is _____ in diameter than the different arteriole, so that glomerular _____ is relatively high.
Marina86 [1]

The afferent arteriole is larger in diameter than the different arteriole, so that glomerular blood pressure is relatively high.

The afferent arterioles are a group of blood vessels that supply the nephrons in many excretory systems. They play an important role in the regulation of blood pressure as a part of the tubuloglomerular feedback mechanism.

The afferent arterioles branch from the renal artery, which supplies blood to the kidneys. The afferent arterioles later diverge into the capillaries of the glomerulus.

The glomerulus (plural glomeruli) is a network of small blood vessels (capillaries) known as a tuft, located at the beginning of a nephron in the kidney. Each of the two kidneys contains about one million nephrons.

The tuft is structurally supported by the mesangium (the space between the blood vessels), composed of intraglomerular mesangial cells. The blood is filtered across the capillary walls of this tuft through the glomerular filtration barrier, which yields its filtrate of water and soluble substances to a cup-like sac known as Bowman's capsule. The filtrate then enters the renal tubule of the nephron.

The glomerulus receives its blood supply from an afferent arteriole of the renal arterial circulation. Unlike most capillary beds, the glomerular capillaries exit into efferent arterioles rather than venules. The resistance of the efferent arterioles causes sufficient hydrostatic pressure within the glomerulus to provide the force for ultrafiltration.

The glomerulus and its surrounding Bowman's capsule constitute a renal corpuscle, the basic filtration unit of the kidney. The rate at which blood is filtered through all of the glomeruli, and thus the measure of the overall kidney function, is the glomerular filtration rate.

The use of DDT as a pesticide is an example of how new technology can have favorable and dangerous long-term outcomes. How does
kipiarov [429]

The right answer is Scientists should conduct long-term studies of DNA technology to determine the consequences.

DDT is a potent insecticide: it kills by opening the sodium channels of insect neurons, destroying them instantly, leading to spasms and then death. Some genetic mutations acting on the sodium channels can make some insects resistant to DDT and other insecticides working on the same principle.

The US Environmental Protection Agency has categorized DDT into the B2 class, that is, potential carcinogen for humans. This supports the fact that the insecticide acts on human DNA.
