Explain why plants can grow at the bottom of the pond (2-3 sentences)

1 answer:

5 0

pond ecology is best described as the interaction of the life in your pond with the environment that exists there. A shallow, nutrient rich pond, exposed to sunlight with little water flowing through it will be teeming with algae and aquatic plants. It may have very little animal life present because of low oxygen levels. In contrast a newly created, deep, spring fed pond may have little life of any kind in it because of low temperatures and lack of food supply.

All ponds age. A pond begins with mostly water, few nutrients, and little aquatic life. Over time the pond accumulates nutrients. This enrichment process is called eutrophication.

hope this helps :) and if you guys need any more help about this stuff just feel free to ask cuz my granpa knows all about this stuff and i always ask these types of questions

Which of the following is not a fate of glucose circulating in the blood of a healthy individual? a) It can be converted to fat.

grin007 [14]

Answer:

B) It can remain, circulating in the blood indefinitely, this is not a fate of glucose circulating in the blood of a healthy individual.

Explanation:

Glucose is produced by breaking down carbohydrates, principally in the small intestine, when we eat a meal containing carbohydrates.This glucose enters the bloodstream.When glucose is in excess, the body stores it away in the form of glycogen in a process stimulated by insulin. Glycogen is a large highly branched structure, made from lots of glucose molecules linked together.Glycogen is mainly stored in the liver and muscles, therefore, excess glucose is removed from the blood stream and stored.

Insulin signals to the cell to translocate Glut 4 to the cell membrane, so that large amounts of glucose can be taken into the cell, via the Glut 4 transporters and converted into glycogen and used as a fuel for cellular activities. Furthermore with the help of insulin, converted into fatty acids, circulated to other parts of the body and stored as fat in adipose tissue.

What is the difference<br>between selective and cross breeding ?

Zinaida [17]

SELECTIVE BREEDING INVOLVES CHOOSING PARENTS WITH PATICULAR CHARACTERISTICS TO BREED TOGETHER AND PRODUCE OFFSPRING WITH MORE DESIRABLE CHARACTERS . ... CROSS BREEDING INVOLVES TWO DIFFERENT BREEDS FROM THE SAME SPECIES TO CREATE A NEW BREED

Why would it be hard to find the CO2 level if the light intensity were very low? HELP!!!!

drek231 [11]

If CO2 was in very small amounts then it would be the limiting factor of photosynthesis, this means the process will take place at a much slower rate because it is lacking one of the raw materials it needs for the process to occur. To find the optimum light intensity you really need all other factors to be at optimum levels or in abundance.

Basic body color for horses is influenced by several genes, one of which has several different alleles. Two of these alleles— th

Phantasy [73]

Answer:

<h2>No,</h2><h2>Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute</h2>

Explanation:

As given:

The chestnut (dark brown) allele and a diluting (pale cream) alleles show incomplete dominance, means that both the alleles in heterozygous condition show their effect. So the heterozygous show the phenotype which is intermediate of both the parents, here a horse heterozygous for these two alleles is a palomino.

There is in fact, no particular allele present for palomino, this phenotype only results due to having two different alleles for a gene. So, palominos can never be pure-breeding because they can never be homozygous.

Let P1 chestnut and P2 dilute,

Palomino is P1P2

The Punnett’s Square for palomino mated to palomino:

P1P2× P1P2

Gametes are: parent-1 P1 and P2 , parent-2: P 1 and P2

Progeny are: P1P1, P1P 2, P 2 P1, P2 P2

Genotypic Ratio: 1 P1P 1 : 2 P1P 2 : 1 P2P 2

Phenotypic Ratio: 1 Chestnut : 2 Palomino : 1 Dilute
