Answer:

The correct answer is - B-DNA is the most common form of the DNA present in the cell and a good approximation of the structure of DNA in the cell.

Explanation:

The B- DNA is a form of the DNA that is explained by Watson and crick by the double-helical structure model. B-DNA is the predominant form of the DNA out of the three forms of the DNA which are B-DNA, Z-DNA, and A-DNA.

B-DNA is is provide a good approximation of the structure of DNA in a cell and its most common form of DNA in a cell that makes it the most studied and focused form of DNA.

Thus, the correct answer is -  B-DNA is the most common form of the DNA present in the cell and a good approximation of the structure of DNA in the cell.

Answer:

B-DNA is the helical form most commonly found in nature.

Explanation:

Even though there are three different helical forms of DNA, molecular biologist primarily focus on B-DNA because is the most commonly found in nature. A very small proportion of Z-DNA is found in negatively supercoiled DNA, and A-DNA is formed when the DNA is facing dehydrating conditions. However, B-DNA is the prominent and active form found in nature, therefore is the most studied.

Answer: Difficulty with communication

Explanation: The cerebral cortex is the thin layer of the brain that covers the outer portion (1.6mm to 5mm) of the cerebrum. It is covered by the meninges and often referred to as gray thing . The cortex is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white. The cortex also covers the cerebellum.

The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and <em><u>speech</u></em>, resulting in smooth and balanced muscular activity

Explain how the structure of compact bone relates to its function.
natka813 [3]

Answer:

Explanation:

Compact bone aka cortical bone is a dense, solid and rigid in which bony matrix with ground org. Substances and salts densely filled and leave tiny spaces known as lacunae. These spaces contain osteocytes also called as bone cells. Inside of these osteons there is a central canal which supplies blood vessels and nerves within bone. These vessels provide blood to the spongy bone and living cells housed within compact bones.

Structure of Compact bone: Basic unit of Compact bone is called osteon also known as haversian system. Each osteon consist of four parts.

1. Haversian canal which consists blood vessels and nerves acts as a site of hematopoiesis which is one of the functions of Compact bone.

2.lamellae are concentric rings of strong matrix consisting Calcium and phosphorus. this gives the bone its strength and hardness to bear body weight.

3.Lacunae contains osteocytes.

4.Canaliculi links osteocytes and provide route for nutrients to reach osteocytes.

What two commandments from god can we obey by a biblical approach to science
lilavasa [31]

Answer:

Here are some. I discovered that the clean and unclean food and hygiene laws found in the Book of Leviticus have been based all this time on the God of Abraham's working knowledge of the germ theory of disease and the modern human body and other advanced fields of science unknown to mankind at that time and some fields of science still unknown to mankind today. These laws and instructions still apply to modern times for all humans to follow to help keep our bodies healthy and disease free until we grow old and die of old age.

Hope It Helps:)
