Tropical rainforest, temperate deciduous forest, and boreal forest (also called the taiga)

1 answer:

3 0

Characteristics that mentioned biomes have in common are:
- They are all forests, dominated by trees and other woody vegetation.
- They inhabit animal life with great microbial diversity.
- They all have big carbon sinks.

Still, trees different in a number of ways in these three biomes:
- Tropical rainforest: Trees are evergreen and have large green leaves. Canopy is multilayered and dense, so there is a little light in the forests.
- Temperate deciduous forest: Trees are deciduous, leaves are lost annually. Canopy is moderately dense, so there is more light than in tropical rainforests.
- Boreal forest: Trees are evergreen conifers with needle-like leaves. Canopy is thick and permits low light penetration.

During nitrification, _____.

Serga [27]

During nitrification, ammonia is changed back into nitrate.

Nitrification is a three-step process of oxidation of ammonia. It is an aerobic process performed by small groups of autotrophic bacteria (Nitrosomonas, Nitrobacter).
First step- ammonia to hydroxylamine,
Second step-hydroxylamine to nitrite,
Third step-nitrite to nitrate.
Nitrification together with ammonification is part of a nitrogen cycle.

In MendAliens, normal head top is dominant to Bart head top, in which the top of the head is jagged. Suppose a MendAlien homozyg

Dafna1 [17]

Answer:

The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)

The genotypes in the F1 generation= Hh

The phenotypes present in the F1 generation= All normal head shape

Explanation:

Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".

In this metabolic process, the enzyme RNA polymerase binds RNA nucleotides (the substrates) together by catalyzing the formation

stira [4]

Answer:

TRANSCRIPTION

Explanation:

Transcription is the first process that occurs in the expression of a gene. It involves the synthesis of a mRNA molecule from a DNA template. The DNA molecule, which is located in the nucleus of an eukaryotic cell, is bound to by an enzyme called RNA polymerase in order to synthesize an mRNA molecule/strand.

RNA polymerase synthesizes a mRNA molecule using complementary base pairing rule i.e. Uracil base (U) is synthesized when Adenine (A) is read, Adenine when Thymine (T) is read, Guanine (G) when cytosine (C) is read, Cytosine when guanine is read. These nucleotide bases are then joined together via chemical bonding.

In a nutshell, RNA polymerase catalyzes the formation of a bond between the backbone sugar of one nucleotide base to the backbone phosphate of another nucleotide base in the metabolic process of TRANSCRIPTION.

During replication and transcription, the DNA unzips the

Pepsi [2]

It has been a while since biology...but if there is one thing I definitely remember, it is the replication process of DNA.

Once the cell is ready to commence the process of replication, it begins by unzipping the double helix. This task is completed by an enzyme called the DNA Helicase. Then a DNA Polymerase takes half of the unzipped DNA strand and creates corresponding deoxyribonucleotides.

Hope I could help! Have a good one.
