Answer:
DNA (deoxyribose nucleic acid)
Explanation:
All viruses contain nucleic acid, either DNA or RNA, but not both, and a protein coat, which encases the nucleic acid. Some viruses are also enclosed by an envelope of fat and protein molecules. In its invective form, outside the cell, a virus particle is called a virion.
Answer:
stratum corneum
Explanation:
Keratin is a structural protein that builds up hair, skin and nails.
The stratum corneum is the outer most layer of the epidermis that contains Keratinized cells. It serves as the primary protective barrier. Its thickness varies throughout the body .
The hair shaft is the part of the hair seen above the skin. Just like the stratum corneum , it is also made up of the protein keratin compacted and fused together.
Answer:
The answer is letter D.
Explanation:
The allele frequencies of the dominant population is: p = 0.967
And the recessive population is: q= 0.033.
Answer:
All of these are correct.
Explanation:
Immune system, reproductive system and nervous system are adversely affected by the contact of highly toxic chemicals because toxic chemicals have materials which is harmful for the cells that the cause of cell death or damaged the structure of the cell due to which the cell can't perform its function efficiently. All the system i.e. Immune system, reproductive system and nervous system are made up of cells so if the cells are damaged by these toxic chemicals the body systems are also negatively affected.
Answer:
a) 0.56moles
b) 2.78moles
Explanation:
The number of moles can be calculated by using the formula;
Mole (n) = Mass (M) ÷ Molar mass (MM)
For a glucose molecule, with chemical formula: C6H12O6
Where atomic mass of C= 12, H=1, O= 16
Molar mass of C6H12O6= 12(6) + 1(12) + 16(6)
= 72 + 12 + 96
= 180g/mol
a) In 100g of glucose;
Mole = 100/180
Mole = 0.56moles
b) In 500g of glucose
Mole = 500/180
Mole = 2.78moles
