A plant with the genotype TT is called _____.
homozygous
heterozygous
hybrid

Answers

This would be a homozygotous plant!

Homozygotous refers to the fact that both genes for a certain characteristics are identical. Heterozygotous refers to the fact that the two genes are slightly different. TT means that both genes are the same, so it's homozygotous!

Answer: The correct answer for the blank is-

homozygous.

Genotype TT represents the genetic makeup of an organism with respect to one particular trait ( let us consider tall height of pea plant).

Homozygpous genotype is the one that contains same variants ( allele) of a gene whereas heterozygous genotype contains two different alleles ( such as Tt).

In this question, genotype TT contains two T alleles ( which are dominant as represented with capital letter). This genotype which will exhibit dominant trait such as tall height of pea plant.

These notes were taken during a class about biological evolution, but the subject title is missing.-results from immigration
-new genes brought into a population
-variation in a population increases

What do the notes describe?
A. gene flow
B. natural selection
C. genetic drift
D. mutation

Answers

Correct answer: A). Gene flow

Gene flow is described as the transfer of genes from one population to another population. It helps to maintain the similarities between the species and prevents the speciation.

The gene flow is a unifying force that prevents the population from diverging. It tries to break down the geographical boundaries, it would otherwise isolate populations.

Hence, the correct answer would be option A.

These notes were taken during a class about biological evolution describes: A. gene flow.

What is gene flow?

Gene flow can be defined as the transmission (transfer) of gene or genetic materials from a specific population of living organism to another. Thus, it helps to enhance and maintain the similarities and unique characteristics that exist between the species of organisms which are living in an ecosystem while preventing speciation.

In conclusion, we can deduce that these notes which were taken during a class about biological evolution describes gene flow such as an increase in population variation or genetic drift.

In ancient times, plant and animal remains got buried, compressed, and transformed into fossil fuels like coal. Burning of these fossil fuels today will affect which biogeochemical cycle? A.
The water cycle

B. The phosphorus cycle

C. The carbon cycle

Answers

Answer: C. The carbon cycle

Explanation:

The burning of the fossil fuel like coal will liberate carbon dioxide and carbon monoxide gases into the atmosphere. The carbon present in this gases circulates among the biosphere, hydrosphere, lithosphere and geosphere. Hence, burning of the fossil will affect the carbon cycle.

Burning fossil fuels will greatly affect the carbon footprint on the planet, as well as the Carbon Cycle.

What are the chemical products of cellular respiration?

Answers

The chemical products of cellular respiration are carbon dioxide, water, and ATP.

What are the chemical products?

Carbon dioxide: Carbon dioxide is a waste product that is produced when glucose is broken down. It is released into the atmosphere, where it is used by plants to make food.

Water: Water is also a waste product that is produced during cellular respiration. It is used by the cell for a variety of purposes, including transporting nutrients and waste products, and cooling the cell.

ATP: ATP is the main energy molecule of the cell. It is used to power all of the cell's activities, including movement, growth, and reproduction.
