Answer:

The correct option is B <em>Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus</em>

Explanation:

a. The thalamus receives stimulus from all of the five senses (sight, smell, taste, hear, touch). FALSE. Olfactory information is not sent to the thalamus for its process. The rest is.  

b. Pressure-sensitive baroreceptors uses tonic receptors which adapt slowly to the stimulus. TRUE. Among the different types of tonic receptors, we may find baroreceptors, irritation receptors, tactile receptors, and proprioceptors. Tonic receptors characterize by their slow adaptation to the stimulus. The first discharge is maximal when the stimulus is received and then it progressively decreases. They send a continuous signal to the CNS.

c. The three layers that the retina is made of: photoreceptors, bipolar cells, rod cells. FALSE. There are in fact three layers in the retina: photoreceptors, bipolar cells, and ganglion cell layers. NOT rod cells.  

d. The sense of smell uses phasic receptors which continuously fire as long as the stimulus is present. FALSE. Olfactive sense uses phasic receptors, but not continuously. These receptors shoot when they receive the stimulus, and then cease if the stimulus keeps constant.

would a scientist who studies evolution also have to learn about other branches of biology? why or why not?
scZoUnD [109]

A man with type A blood marries a woman with type
JulsSmile [24]
The pattern of inheritance is called codominance when the father has type A and the mother has type B and the kids have type AB blood. This is when the both of the alleles will show equal dominance/impact after mating. The type A blood has the gene pattern iAi or iAiA. The type B blood has the gene pattern iBi or iBiB. The correct answer to this question is "codominance."

The inheritance of eye color in Drosophila is controlled by genes on each of the fly's four chromosome pairs. One eye-color gene
algol [13]

Answer:

F1 Females  - all wild type

F1 Males  - all wild type

F2 Females  -  - all wild type

F2 Males - 1/2 wild type, 1/2 vermilion

Explanation:

The wild-type allele (Xᵛ⁺) is dominant over vermilion (Xᵛ), which is a sex-linked trait.

Female flies have two X chromosomes, male flies have one X and one Y chromosome.

A homozygous wild-type female fly (Xᵛ⁺Xᵛ⁺) is mated with a vermilion male fly (XᵛY).

The female parent can only produce Xᵛ⁺ gametes.

The male parent can produce either Xᵛ or Y gametes.

When gametes from both parents fuse, the F1 offspring will have the genotypes Xᵛ⁺Xᵛ (females with wild type eyes) and Xᵛ⁺Y (males with wild type eyes).

The F1 females can produce Xᵛ⁺ and Xᵛ gametes. The F1 males can produce Xᵛ⁺ and Y gametes.

When the F1 individuals interbreed, the gametes combine to give rise to the F2 offspring. The possible combination of gametes that will give the different genotypes and phenotypes in the F2 are:

  • Xᵛ⁺Xᵛ⁺ females with wild type eyes
  • Xᵛ⁺ Y males with wild type eyes
  • Xᵛ Xᵛ⁺ females with wild type eyes
  • Xᵛ Y males with vermilion eyes

How can a temporary lake create salt flats in Death Valley?
evablogger [386]

Answer:

A temporary lake create salt flats in Death Valley when Holocene lakes began to evaporate.

Explanation:

"Each time it has rained since, a new layer has been added. The flat is a vast area covered in salt that was deposited from evaporated water. When the water runs down the mountain, it dissolves minerals that precipitate out as the water evaporates."

Hope this helped!
