Rock pocket mice are rodents found in the desert Southwest. They are typically light/tan, but a mutation in the population codes

for a
darker fur color. The two fur colors are shown in the images here. The area where these mice live typically have a sand with a tan
background. However, there are areas of cooled lava from a volcanic eruption 10,000 years ago that deposited black rock. The mice
are found on the sand and on the rocks.
Researchers set traps to collect samples of mice from the rocks and the sand areas. An analysis of the data for the mice caught in
each of the areas would show which trend if natural selection were acting on the different phenotypes?

Which of the following accurately pairs the phase of the cell cycle with its primary purpose? A. S phase–DNA replication B. G2 p
GenaCL600 [577]

The correct answer is option A, S Phase - DNA Replication

The DNA replication begin at the S phase of the cell cycle. In this phase, the cell grows and prepare itself for the DNA replication while the other components such as centro some undergo replication. The S phase occurs during the inter phase and the genetic material duplicates itself before entering the mitosis and meiosis cell division in the next stage.

Describe some of the effects that dilated blood vessels will have on blood pressure.
grin007 [14]
Since pressure is force per unit area, blood pressure could be thought as the force exerted by the blood to the surface area of your blood vessels. When your blood vessels dilate, it means that they expanded. The result would be faster flow of blood. When this happens, the force of the blood is not any more concentrated on your blood vessels because there is more room available. 

Think of a faucet where tap water flows. When you stopper the faucet with your finger, you feel the force of the water. The pressure builds up as manifested by the sound your faucet makes. But when you release your finger, the water rushes through and flows faster. The pressure is released. Therefore, when your blood vessels are dilated, your blood pressure decreases.

Fofino [41]

Answer:

A hypothesis that is not possible, or has less strength, to explain how life arose on Earth is that it originated from cells that were delivered by meteorites from outer space (option D).

Explanation:

Although it is a hypothesis that has scientific foundations to be considered, the origin of life coming from organic molecules or cells from space -called Panspermia- has not been completely proven because:

  • It provides information on the origin of cells or organic matter, but it doesn't specify how life was formed from them.
  • It does not resolve the question of how a cell could withstand a journey through space or endure the high temperatures when a meteorite entered the primitive atmosphere.

These arguments make the hypothesis of the arrival of the first cells from outer space the least accepted today.
