Answer:
the flow of individuals in and out of population
The options in the question are shown in the image attached to this answer
Answer:
A
Explanation:
A peptide bond is formed between a carboxylic acid and an amine group. These two functional groups must be in the correct orientation before they can react to form the peptide bond.
If we study the images closely, only the amine group and carboxylic acid in option A are correctly positioned for reaction to take place leading to the formation of a third peptide bond.
1.
G - dominant trait (golden)
g - recessive trait (white)
Heterozygous - Gg
White (homozygous recessive) - gg
P: Gg x gg
(picture 1)
Genotype: 50% Gg 50% gg
Phenotype: 50% golden 50% white
2.
R - dominant (red)
r - recessive (yellow)
RR - red
rr - yellow
Rr - orange
P: rr x Rr
(picture 2)
Genotype: 50% Rr 50% rr
Phenotype: 50% orange 50% yellow
Answer:
Cancer is characterized by uncontrolled growth and division of certain body tissues, so forming a tumor. A tumor results from uncontrolled growth of cells but all tumors are not cancerous.Based on their spread tumors are classified as benign and malignant. A benign tumor remains confined to the particular organ and do not spread to other parts as these are enclosed in a sheath of connective tissue.Malignant tumors grow slowly during the latent stage but soon they start growing faster and start effecting the normal functioning of surrounding tissue. This stage becomes the metastatic stage and the cells from the tumors metastasize i.e. they break from the tumor and migrate to other body organs through the blood or lymph.
Early detection of cancer is necessary because in later stages it becomes incurable most of the time, the most frequently used method is biopsy, Endoscopy, DNA probe analysis radio-logical techniques etc.
Answer:
B) CO
Explanation:
Chemical decompsition or breakdown is defined as the process in which a substance can be broken down into simpler compounds through chemical means.
CO or carbon monoxide can be decomposed by chemical change because it can be broken down into into carbon and oxygen.
While Co (cobalt), Cr (chromium), and Cu (coppoer) are present in its simplest form and can not be decomposed further.
Hence, the correct answer is "B) CO".
