4. Genes that are responsible for new characteristics that help a species survive in a particular environment
are most likely to do which of the following?
A. rapidly decrease in frequency
B. gradually decrease in frequency
C. increase in frequency
D. not change in frequency

Answers

Answer 1

Answer:

The correct answer is - increase in frequency.

Explanation:

According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.

According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants with wrinkled seeds.

What was a conclusion Mendel drew from the F1 generation of this cross?

Answers

Explanation:

Traits are inherited in discrete units, and are not the results of "blending." ... traits can be dominant or recessive, and the recessive traits were obscured by the dominant ones in the F1.

Answer:

The dominant factor, or allele, is for round seeds.

Explanation:

The factors (or alleles) don't disappear when two species are crossed, so "the factors or alleles for round seeds disappear completely from the plants" and "the factors or alleles for wrinkled seeds disappear completely from the plants" are both incorrect. From the drawing, we can see that the F1 generation is a round seed, meaning the dominant factor is for round seeds. Hope this helps!

Which of the five stages of respiration takes place at the alveoli?

Answers

Answer:

External respiration is the exchange of gases with the external environment, and occurs in the alveoli of the lungs.

The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. External Respiration. Exchange of gases between air and blood at pulmonary capillaries (Alveoli) is the second stage. So it would be the 2nd stage

What structures are responsible for the movement of chromosomes to the center of the cell in metaphase and their separation in anaphase?

Answers

The structures that are responsible for the movement of chromosomes to the center of the cell in metaphase is the spindle fibers, the cell attaches the centromeres to the spindle fibers to pull the sister chromatids to the center

In anaphase the sister chromatids are separated at the centromere and are pulled to the opposite poles of the cell by the spindle fibers

Tropical rain forests receive heavy rainfall. How do the trees and plants of this region withstand rotting?

Answers

Answer:

The trees and plant withstand rotting in tropical rain forest using some of these mechanisms.

Explanation:

Tropical rain forests are known for the presence of heavy rainfall, due to this, there might be a lot of water retention in the root. Some trees and plants however are able to store this water and use some of the below mentioned methods to prevent decay and rot.

Some trees in the tropical rain forest may produce very hard outer layer, these hard outer layer will protect the plant and trees form predators and microorganisms from penetrating into the inner tissues of the tree.

Some withstand rotting by producing chemical compounds, these chemical compounds prevents predators and microorganisms from destroying the plants and trees.

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?

A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.

C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.

D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.


I think it’s B, but I’m not completely sure. Help please!

Answers

Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.

Explanation:

The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.

With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

What provides evidence of an increase in animal species at the same time that atmospheric oxygen concentrations increased?

ts fossil records but i need an explination

Answers

Answer:

Fossil records provide evidence of an increase in animal species at the same time that atmospheric oxygen levels increased.

Explanation:

A huge diversification among animal species occurred with the increase in the levels of atmospheric oxygen. The reason why the number of species increased drastically was that a whole new world opened up, the land. The land was open for exploitation and taking over, with every single niche free, so animals diversified and filled in pretty much all of the niches. The fossil records give us clues when this happened, as from only microorganisms there is a sharp rise in complex animals, coinciding with the increase of oxygen levels.

If it wasn't for the increase of atmospheric oxygen though this wouldn't have been possible. The oxygen in the atmosphere enabled animals to breathe on land. Also, it cooled off the global temperatures which were too high before the increase of atmospheric oxygen, making them suitable for life. And last but not least, the atmospheric oxygen resulted in the formation of the ozone layer, a layer that started to act as protection from the UV rays.

a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms

Answers

Answer:

b The other fossils are about 300 million years old

Explanation:

From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.

Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.
