Why does it rain more heavily on the windward side of mountain ranges?

A.Air masses absorb moisture as they increase in altitude, form clouds which precipitate rain.
B.Cool air on the lee side of the mountain encounters warm moist air from the windward side causing it to give up moisture.
C.Prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing rain.
D.Cool, moist air from the oceans warms over land and precipitates rain on the windward side of mountain ranges.

Answers

B.cool air on the lee side of the mountain encounters warm moist air from the windward side causing it to give up moisture

It rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.

What are the prevailing winds?

This is a type of wind that blows in a specific direction over a certain area, and its strength can be influenced by many factors, like the elevation of the land, temperature and pressure differences between air masses, earth rotation, etc. In a mountain range, the prevailing winds carry moist air to the top of the slope, where it cools and releases precipitation, that causes the rain.

Hence, it rains more heavily on the windward side of mountain ranges because prevailing winds bring warm, moist air masses from sea level to high altitudes, cooling the air and causing the rain that is in Option C.

This is a base deletion

evaluate each of the statements below. select those that accurately describe the role of genes and chromosomes in the process of inheriting a specific trait. choose all that apply.

A) chromosome are made of DNA.
B) there are 26 pairs of chromosomes in humans.
C) alleles are the different forms of a gene that can exist.
D)chromosomes contain genes that control the inheritance of traits.
E)genes are made of chromosomes and contain all of the genetic information for an organism.

Answers

D)chromosomes contain genes that control the inheritance of traits.

The statements 'chromosomes are made of DNA', 'alleles are the different forms of a gene that can exist' and 'chromosomes contain genes that control the inheritance of traits' are TRUE (Options A, C and D).

Chromosomes are linear fragments of DNA that contain part of the genetic material in eukaryotic organisms.

Alleles are different gene variants. In diploid (2n) organisms, one allele for a given gene locus is inherited from the mother, whereas one allele of the same gene is inherited from the father.

Genes contain the instructions that are inherited across generations in order to synthesize proteins (both structural and enzymatic proteins), which largely determine the phenotypic traits of an organism.

In conclusion, the statements 'chromosomes are made of DNA', 'alleles are the different forms of a gene that can exist' and 'chromosomes contain genes that control the inheritance of traits' are TRUE (Options A, C and D).

PLEASE HELP!! in the process of translation, the ribosome is the site where---

a. free floating amino acids are picked up by tRNA
b. information from DNA is copied to RNA
c. DNA strands are separated and copied
d. amino acid chains are assembled from information in the mRNA

Answers

Answer:

d. amino acid chains are assembled from information in the mRNA

Explanation:

The ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).

During gene transcription, a sequence of DNA called gene is used as a template to create a messenger RNA (mRNA).

Subsequently, this mRNA travels to the ribosome to be used as a template for the creation of a protein by the process of translation.

The ribosome is the site where successive amino acids are added to the growing polypeptide according to the order of triplets of nucleotides or 'codons' in the mRNA sequence.

In conclusion, the ribosome is the site where amino acid chains are assembled from information in the mRNA (Option d).

Osmosis requires energy

True
Or
False

Answers

Answer:

Diffusion and osmosis don't require the cell to expend any of its own energy, as they are passive processes. As we know both are passive processes and yet (in basic, short terms) diffusion is higher to lower and osmosis is lower to higher, so movement to concentration doesn't determine whether it is active or passive.
