Answer:
(A) Bioaccumulation
Explanation:
When the concentration of certain substances in the bodies of the organisms of various trophic levels keeps on increasing as they pass through the food chain, the process is called bioaccumulation or biomagnification.
Most of the organic non-biodegradable pollutants/chemicals exhibit bioaccumulation. Being insoluble in water, these chemicals are accumulated in the fat tissues of the organisms.
As the predator feeds on the prey having a non-biodegradable chemical in its tissues, the chemical enters the body of the predator.
As these chemicals pass through the food chain, there is a gradual increase in their concentration stored in the living tissues of the organisms. Therefore, the top consumers exhibit maximum bioaccumulation of contaminants in a food chain.
Answer:
The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.
Explanation:
From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...
The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.
The minerals and vitamins present are in a way they can be absorbed.
Answer:
All crosses and proportions, genotypes and phenotypes are attached.
Explanation:
a. Within living organisms, staining is a characteristic governed by a polygenic inheritance, which means that there is more than one gene involved in the staining process. as you already know, each gene has two alleles, if a trait is controlled by 2 genes, it means that we will have 4 alleles at the crosses.
From the description between dominance and recessivity between the alleles that control the colors of the pepper, shown in the question above, we can see that for the crossing between a red pepper and a green pepper, being able to generate a completely orange offspring, it would be necessary that the genotype of the parent peppers was: Red: RGRG, green: rgrg.
This would generate an orange-colored RrGg offspring, as you can see at the F1 crossing.
b. When individuals of F1 offspring are crossed, the combination of alleles and the determination of genotypes and phenotypes becomes much more complex, because instead of 4 alleles, we will have the combination of 16 alleles among themselves. Once again we will need to rely on the description of dominance and recessivity shown in the question above, so that from the crossing between the alleles of each gene, we can reach a conclusion, as you can see in the F2 crossing.
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
Explanation:
It sends message directly to muscles and glands
