Suppose a drug is developed that blocks K+ leakage channels. The drug prevents ions from passing through those channels. If this
Sav [38]

Answer: 1. The resting membrane potential would become less negative (more positive).

Explanation:

Resting membrane potential is a voltage carried by a resting (non-signaling) neuron, or called as resting potential, across its membrane.  The resting potential is determined by ion concentration gradients across the membrane, and the permeability of the membrane to each ion form.  

In a resting brain, there are gradients of concentration across the Na+ and K+ membranes. Forces shift their gradients down through channels, resulting in a separation of charges that provides the potential for rest. The membrane is much more permeable to K+ than to Na+, so the resting potential is similar to K+'s potential for equilibrium.

Hence, the correct option is 1. The resting membrane potential would become less negative (more positive).

4. A white albino rabbit lacks fur color. It carries the alleles rr. What is its
Marta_Voda [28]

Answer:

The phenotype of the rabbit is the absence of fur colour and the genotype is the alleles rr.

Explanation:

The genotype can be described as the genes which are present in an organism. Genes are made up of alleles. As the rabbit in the question carries the alleles, rr, hence it is the genotype of the white albino rabbit.

The phenotype can be described as the physical appearance that results from the particular genes present in an organism. As the white albino rabbit carries the alleles,rr, due to which it doesn't have fur, hence no fur is the phenotype of it.

Assume sexual reproduction occurs. What is the number of chromosomes in the zygote if the parent's reproductive cells or gametes
Rudik [331]
<span>If the parent's reproductive cells or gametes contain 12 chromosomes each, the number of chromosomes in the zygote is 24. Fertilization is the fusion of two haploid gametes and results in the creation of a diploid zygote. If two haploid gametes containing 12 chromosomes each fuse, the zygote will have 24 chromosomes (12 + 12 = 24).</span>

Which of the following is NOT a characteristic of the northern boreal forest (taiga) biome?
Alik [6]

Answer: d. High biodiversity in the understory.

Explanation:

The taiga or boreal forests are the largest biome in the world. These can be found in the regions of North America, Alaska, and United States. These regions exhibit extreme weather conditions. Typically long winters and moderate to high precipitation. The soil is permafrost and nutrient poor as no new organic matter can be added up to the soil due to it's freezing condition. The plant growth is scanty and biodiversity is low because organisms are incapable of surviving in the harsh weather conditions.
