Answer:
The genetic material of most of the organism is Dexoxy-ribonucleic acid OR DNA which are formed of the monomer unit called nucleotide.
Each nucleotide is composed of a 5-C deoxyribose sugar, a phosphate group and 4 types of nitrogenous bases mainly adenine, cytosine, guanine and thymine.
It is the sequence of these nitrogenous bases which determine the fate of a cell as these nitrogenous bases are read by the ribosome in the form of triplets called codons where each codon codes for specific amino acids. These amino acids bind to each other via peptide bonds to form proteins.
Thus, these nitrogenous bases control the important property of the cell.
Answer:
facts: The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose.
opinions: Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment. Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points.
Explanation:
Answer:
Th correct answer is A. Capsid
Explanation:
T-2 phage is a bacteriophage which is virulent to E.coli which means T2 phage infects E.coli. The genetic material of T2 phage is linear DNA which is double-stranded. The genetic material of T2 phage is enclosed in a protein coat which is called capsid.
This capsid protects the genetic material of bacteriophage by any enzymatic digestion, helps the virus to attach the host cell and helps the virion to penetrate the cell membrane of the host cell and inject its genetic material in the host cell. Therefore capsid is the correct answer.
1st of all arteries have a thick walls while veins have have a thin wall
Answer to why arteries have thick walls: arteries have thick walls because blood flows inside them with high pressure and with a high speed
Answer:
C) The rate applies to more individuals each year.
Explanation:
Suppose the initial population was 200 people and birth rate was 10% of that. So thats 0.10 * 200= 20 babies that year.
Next year the population is 200+ 20 = 220 people. Now if the birth rate is still 10% then you will have 0.10 * 220 = 22 babies that year.
Did you see that? The number of babies increased by 22-20= 2 extra babies each year.
Therefore, since rate applies to more individuals each year, you'll get increase in population
