Answer:
The correct answer will be option-E
Explanation:
The autonomic nervous system or ANS activity in the brain is mainly controlled and regulated by the hypothalamus structure. The autonomic centres of the hypothalamus control the hormonal secretion adrenal medulla like adrenaline and norepinephrine.
The secretion of the hypothalamus controls the activity of the vasomotor center which help maintain the blood pressure.
Thus, option-hypothalamus is the correct answer.
The answer <span>is AB and aB
<span>A man is heterozygous for sickle cell anemia: Aa
</span></span>A man is <span>homozygous dominant for familial hypercholesterolemia: BB
So, his genotype is AaBB. He will give only one allele of two for each gene.
He can have 2 different combinations in sperm cells:
- AB
- aB</span>
Answer: Cell
Explanation:
The cell is the structural and functional unit of life. It is the the most basic level. A life starts from a single cell.
When a male and female gamete(germ cell) fuse together they form zygote. Firstly it is a single cell surviving inside the mother's womb.
Then differentiation takes place and the cell keeps on dividing to form different tissue layers and then organs form which makes a complete baby. Hence, zygote and germ cell are cellular level of organization.
I think it should go:
1)Dissolved minerals
completely cement
the sediment together.
2)The sediment is
gradually buried
and compacted.
3)The sediment is
deposited by wind,
flowing water, or
other natural
processes.
i hope it’s correct and i helped :)!
Answer:1.c 2.d 3. d
Explanation:
The DNA hyperchromic effect can be defined as the absorbance of radiation or light by the nitrogen bases of DNA. This phenomena is effective when the DNA is in single stranded condition. For observing the hyperchormic effect the DNA is required to be denatured at high temperature or by increasing the level of pH.
The two strands of the DNA when get separated the absorbance of the DNA solution also increases. This results due to reduction in the base-base interaction and hence, increases the absorbance of light like UV by the bases.
