In certain mice, long tails (T) are dominant over short tails (t). If 2 hybrid mice mate, what will the outcome be?
Answers
Answer:
3 long tails : 1 short tail
Explanation:
This question involves a single gene coding for tail length in mice. The allele for long tail (T) is dominant over the allele for short tail (t). This means that an heterozygous mice will possess the long tail length.
According to this question, in a cross between two hybrid or heterozygote mice i.e. Tt × Tt, the following gametes will be produced by each parent:
Tt - T and t
Using these gametes in a punnet square (see attached image), the following will be produced: TT, Tt, Tt and tt.
Offsprings with genotype TT, Tt and Tt will have a LONG TAIL while genotype tt will have a SHORT TAIL. Hence, the phenotypic ratio will be 3 long tails : 1 short tail.

plant breath through
Answers
Answer:
Plants respire through plant pores, called stomata. During respiration and photosynthesis, gases go in and out of the plants through stomata using diffusion, not breathing.
Answer:
respiration
Explanation:
Plants breathe through a process called respiration, where they exchange gases between the outside and the inside of their bodies as a living organism. They breathe through openings called stomata. Photosynthesis makes a plant produce oxygen, but a plant also requires oxygen constantly.

What are convection currents?A process that involves the transfer of energy from one location to another is a convection current. It is also known as heat transfer by convection.
Convection currents are fluid movements brought on by temperature or density variations within a substance. Because the particles within a solid are fixed in place, convection currents are only visible in gases and liquids. A straightforward illustration of convection currents is warm air rising toward a home's ceiling or attic.
Therefore, the correct option is
A. Conventional currents in the Earth's mantle.
B. sea-floor reading results in
C. The ocean is changed in C. size and shape.

The circled portion of DNA labeled X in the following picture is a
a phosphate group
b sugar
c nucleotide
d aldehyde base
Answers
Answer:
a. Phosphate group
Explanation:
The circled portion of the DNA labeled X is ; ( C ) Nucleotide
The Nucleotide in a DNA molecule is the building block of the nucleic acid and it consists of a sugar molecule, A phosphate group ( P ) and nitrogenous base like adenine, cytosine or guanine.
The circled portion covers a nitrogenous base ( cytosine ), a phosphate group and a sugar molecule therefore the circled portion correctly represents a Nucleotide in a DNA molecule.
Hence we can conclude that the circled portion of the DNA is Nucleotide.

Based upon data from the Human Microbiome Project (HMP), define microbial antagonism and discuss how the various microbial populations keep each other "in check" with consequences for human health.
Answers
Answer:
Suppression of one microorganism by another microorganism.
Explanation:
Microbial antagonism is the suppression of one microorganism by another microorganism. For every organism, God creates another organism in order to control its growth and population. So harmful microorganisms that cause diseases in human can be controlled by another beneficial microorganism. If the beneficial microorganisms are removed from the environment, the harmful microorganisms causes more damage to human and their property.
Microbial antagonism refers to competition between microorganisms in the same environment. This limits the growth of the microorganism population, protecting human health.
We can arrive at this answer because:
Microbial antagonism occurs when two different species of microorganisms are in the same environment and compete for the same resources.This competition limits the growth of the two species and can even suppress the population of each other.This type of biological system is beneficial in keeping populations of microorganisms, which can have negative effects on humans, under control, preventing proliferation, and maintaining human health and integrity.

B) Does DNA methylation prevent independent assortment during metaphase II?
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
D) Do daughter cells that are not genetically identical to parent cells produce viable zygotes?
Answers
C) How does the independent assortment of the two sets of homologous chromosomes increase genetic diversity?
What is independent assortment?Independent assortment is a mechanism that contributes to genetic diversity during meiosis. It refers to the random alignment and separation of homologous chromosomes during the first meiotic division (meiosis I), which leads to different combinations of chromosomes being passed on to the daughter cells.
This means that each daughter cell will have a unique combination of chromosomes. When the gametes (sperm or egg cells) produced by meiosis fuse during fertilization, they can give rise to offspring with a unique combination of genetic information, further increasing genetic diversity within a population.

What species concept best applies to this situation.

Answer:
Specie is a group of organisms that can interbreed with one another and produce fertile offspring.
Explanation:
Species Concept that applies to this situation is that a specie is a group of organisms that can interbreed with one another and produce fertile offspring.

Answers
Answer:
Water is precious since it is one of the most basic commodities that sustain the life of human beings, animals and plant. Without water, it would be impossible for any form of life to exist in the universe. Close to 75% of the Earth is covered with salt water, while 2% of the surface contains frozen water.
Explanation:
Why is water a precious resource?
It is needed for all living things and must be managed well to ensure we have enough for our needs and to protect our environment. Water is a precious resource. We can't live without it. Clouds formed by this vapor ensure that water falls back down to Earth as rain, sleet, snow or hail.Water resources are sources of water that are useful or potentially useful to humans. It is important because it is needed for life to exist. Many uses of water include agricultural, industrial, household, recreational and environmental activities.
