Answer:
The cow uses all but stores ten percent of what they eat.
Explanation:
For example, a plant produces 100 percent energy. The plant needs to use the energy for survival.
When a cow eats the plant, it only gains 10 percent of the energy.
Then, say a wolf eats the cow.
The wolf only gets 1 percent of the energy that is produced by the plant.
Answer:
The development of the brain continues past childhood. For example, if a monkey pushes a lever with its finger several thousand times a day, the Brain tissue that controls the finger changes as a result of the experience.
<span>Parents can pass on chromosomes to their children that are different than their own when the new gene combinations are created by crossing over. The exchange of genetic material between homologous chromosomes is known as crossing over which occurs in meiosis. When homologous chromosomes pair up and exchange different segments of the genetic material. As the result, a new combination of genes will be formed. If there was not crossing over, all genes on a chromosome would be inherited together.</span>
Answer:
The first male was bb Ee, and the second male was bb EE.
Explanation:
In Labradors coat colour is controlled by two genes. Suppose the two genes are B and E. B produces black colour and recessive form bb gives brown colour. Gene E is epistatic over gene B in its recessive form which means that ee will produce yellow colour regardless of the genotype present of B gene.
The first case is possible if the female lab is bbee (yellow) and the male lab is bbEe (brown):
bbee X bbEe
bE be
be bbEe bbee
So half of the offspring will be brown (bbEe) and half of them will be yellow (bbee)
The second case is possible if the same female bbee mates with a brown male of different genotype which can be bbEE:
bbee X bbEE
bE
be bbEe
So all offspring will be brown (bbEe)
Hence, the first male was bbEe and the second male was bbEE.
Answer:
Basophils of the blood help to get defensive leukocytes to the site quickly by releasing an anticoagulant called ___heparin_______ and a vasodilator called _____histamine_____
Explanation:
Basophils are a type of white blood cell containing specific granules that release histamine (vasodilator) and heparin (a substance with anticoagulant action) and azurophilic granules that contain lysosomes. They are important in allergic and anaphylactic processes.
