Answer:

Peristalsis moves food through the digestive system with alternating waves of muscle contraction and relaxation. Digestion includes both mechanical and chemical processes. Mechanical digestion is a purely physical process that does not change the chemical nature of the food.

Answer:

Digestion of food is a process which starts from mouth and continuous till intestine. The mechanical process which are involved is movement of tongue, chewing through teeth, peristalsis, etc.

Explanation:

Digestive system of a body includes mouth, food pipe, stomach, intestine. This system breaks down the food that a person eats into small particles which is helpful for conversion of food into energy. This energy is utilized by the body to perform different life functions.

The essential minerals and vitamins which are present in the food are absorbed in intestine. When we eat food, the food gets mixed with saliva which is present in our mouth. This mixing is necessary for the digestion of food.

which structure within a bone contains cartilage cells that divide and increase the size of the bone until adulthood?

kogti [31]

Epiphyseal plate is the structure within a bone that contains cartilage cells that divide and increase the size of the bone until adulthood.

The epiphyseal plate, also known as epiphysial plate,or physis, or growth plate, is a hyaline cartilage plate in the metaphysis at each end of a long bone or diaphysis. The plate is found in children and adolescents; in adults, who have stopped growing, the plate is replaced by an epiphyseal line<span>.</span>

If a DNA strand contains the sequence 5Ê¹-ATTCCGGATCGA-3Ê¹, which of the following is the sequence of the complementary strand o

Svetllana [295]

Answer:

5Ê¹-ATTCCGGATCGA-3Ê¹

Explanation:

In a double-stranded DNA, two strands are held together with the help of hydrogen bonds between nitrogenous bases and the two strands are anti-parallel, means one strands runs in 5' to 3' direction, while another strand runs in 3' to 5' direction.

According to complementary base pairing rule, adenine makes bonds with thymine and thymine makes bond with adenine; similarly, guanine makes bonds with cytosine and cytosine makes bonds with guanine.

Thus, the complementary base pairing rule, complementary sequence for given DNA sequence would be:

5Ê¹-TCGATCCGGAAT-3Ê¹

3Ê¹-AGCTAGGCCTTA-5Ê¹, which can be also written as

5Ê¹-ATTCCGGATCGA-3Ê¹.

Thus, the correct answer is 'second option.'
