How Plants Acquire Their Energy

Plants must get food into their systems in order to acquire energy and continue living, similar to animals. Plants create energy for animals to use, so they must replenish their nutrients. And plants breathe, in a way. They take in the carbon dioxide that all the animals give off, and they give off oxygen for all the animals to use. Pretty cool design, isn’t it?

Making energy from the ultimate energy source

Photosynthesis is the process by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel. Here is how it works.

GalinKa [24]

Answer:

It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.

We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.

We should give the awareness to the general public related to decrease the recreational fishing impact.

Commercial fishing must be ban until we reaches the sustainable level of fish.

There must be place international limits to every country related to limited number of fish they can take.

Which of the following is considered a stressor in a marriage? A. Having financial trouble B. Having respect for each other C. S
Elenna [48]

Answer:

A

Explanation:

You have to pick something that is negative, something that you would like to have happen.

B is definitely not the answer. You like each other and have respect, that's the bare minimum for a good relationship.

C this one is kind of iffy. If you are playing bridge, that's one thing. If you are dancing too close and drinking, that's another.

D Feeling content. That's practically spells a good marriage.

A If money is a problem, the marriage likely is going to have problems.

In cats, the dominant O allele of the X-Iinked orange gene is required to produce orange fur, the recessive o allele of this gen
Yuliya22 [10]

Explanation:

Female cats have two X chromosomes. In the early stages of mammal development each cell in the embryo will randomly inactivate one of the X chromosomes, and all of its daughter cells will keep that same X chromosome inactive (its genes won't be expressed).

For that reason, the adult individual will have patches of cells that express the genes of only one X chromosome, and patches of cells that express the genes of the other one.

<h3>a) What type of crosses would be expected to produce female tortoiseshell cats? </h3>

The female tortoiseshell cats have patches of cells that express the dominant <em>O</em> allele and patches of cells that express the recessive <em>o</em> allele. That means that they have the genotype XᴼXᵒ.

These females can come from the crosses of:

  • XᴼXᴼ x XᵒY: Orange female x black male
  • XᵒXᵒ x XᴼY: black female x orange male
  • XᴼXᵒ x XᵒY: tortoiseshell female x black male
  • XᴼXᵒ x XᴼY: tortoiseshell female x orange male

<h3>b. Suggest a hypothesis to explain the origin of male tortoiseshell cats</h3>

Male cats normally have one Y chromosome and <u>one</u> X chromosome, and their fur will have the color determined by the allele of the O/o gene in the X chromosome they have. However, in rare cases males can have two X chromosomes and a Y chromosome. If the genotype is XᴼXᵒY, the males will also inactivate one of the X chromosomes randomly in each cell, giving the tortoiseshell phenotype.

<h3>c. Calico cats (most of which are females) have patches of white, orange, and black fur. Suggest a hypothesis for the origin of calico cats.</h3>

The patches of white are determined by another gene (Piebald Spotting, with the alleles S/s) in an autosomal chromosome, that basically causes unpigmented fur. A homozygous genotype <em>SS </em>produces large patches of white fur, the heterozygous <em>Ss</em> genotype causes smaller patches of white, and the homozygous <em>ss </em>genotype determines the lack of white color.

Female Calico cats would have the genotypes XᴼXᵒ SS or XᴼXᵒ Ss.
