You have just eaten a ham and cheese sandwich for lunch. Explain the all of the digestive processes (mechanical and chemical) that occur as you eat then digest the sandwich. Start in your mouth and finish at the end of the small intestine. Be sure to include all of the digestive organs and enzymes involved and specify how the carbohydrates, lipids, and proteins are broken down and absorbed.

Answers

Answer:

The digestion starts with the buccal cavity or mouth by chewing the food. Teeth break the ham and cheese sandwich into small and digest the starch present in the food with help of the amylase enzyme present in saliva. The small chewed particles of food mixed with saliva called bolus move to the stomach.

In the stomach, there is HCl acid present that killed any harmful microorganism present in the bolus and digests the protein present in the ham and sandwich by pepsin enzyme secreted by the parietal cells of the stomach.

Lipase digest fat present in the cheese of sandwich by gastric juice. Small intestine digest fat by lipase protein by protease and carbs by amylase.

Absorption takes place in the small intestine that contain numerous villi’s projections in the cell lining for absorption in the small intestine.

d. every muscle has one motor unit so they have slightly different frequencies.every muscle has one motor unit so they have slightly different frequencies.
e. each motor unit can innervate a different number of muscle fibers.each motor unit can innervate a different number of muscle fibers.

Answers

Answer:

a. every muscle has a varying number of motor units so they can generate different frequencies.

e. each motor unit can innervate a different number of muscle fibers.

Explanation:

Electromyography (EMG) is a diagnostic procedure used to measure the response of muscles and nerves to electrical activity. A motor unit is composed of one motor neuron and muscle fibers it innervates. The number of muscle fibers in each motor unit can vary among different muscles and even among motor units within the same muscle. Each motor unit is known to innervate a variable number of muscle fibers, but each single muscle fiber is innervated by only one motor.

An electromyography (EMG) read out has all motor units looking different

because

Every muscle has a varying number of motor units so they can

generate different frequencies

Each motor unit can innervate a different number of muscle fibers.

Electromyography (EMG) is used in diagnostics for measuring the

relationship between muscles and nerves through responses to electrical

activity.

The body has muscles with no constant number of motor units as it varies.

Each motor unit also supply nerves to different number of muscle fibers

which explains the difference in motor units during electromyography.

An atom has an atomic number 17 and atomic mass number 35. How many neutrons are present in its nucleus?
A 17
B. 18
C. 35

Answers

Answer:

B. 18

Explanation:

An atom, which is the smallest indivisible particle of matter, further contains certain particles called SUB-ATOMIC PARTICLES namely: proton, neutron and electron. In a neutral/uncharged atom, the number of proton is equal to the number of electrons. The number of protons in an atom represent its ATOMIC NUMBER.

However, the sum of the proton number and neutron number gives the MASS NUMBER i.e. mass no. = proton no. + electron no.

Hence, according to this question which states that an atom has an atomic number of 17 and a mass number of 35. The neutron no. can be calculated as follows:

Neutron no. = mass no. - proton no.

Neutron no. = 35 - 17

Neutron no. = 18

Answer:

B. 18

Explanation:

35 - 17 = 18

Why may there be variations in plants grown from seeds?

Answers

Answer:

Because the seeds are formed as a result of sexual reproduction, which brings about genetic variation

Explanation:

Ideally, the chances of genetic variation in organisms increases as a result of sexual reproduction. Specifically, the meiotic process in sexual reproduction ensures this. Seeds are plant structures used for propagation, as they grow and develop into new organisms.

A plant propagated by SEEDS will possess variation because the seeds were formed from sexual reproduction i.e. fertilization of male gamete (pollen) and female ova. Note that each of these gametes that combined to form a seed, were produced by meiotic division.

A long, thin tube called the pollen tube develops from the pollen grain once it touches the flower's stigma this pollen tube allows sperm cells of plants to move through the style. So, the answer is Pollen tube.

When a female gametophyte undergoes double fertilization, male gametes or the sperm cells are transported to the female gametophyte via pollen tube, which results in the production of the seed.

Two sperm cells are found in the pollen tube, which grows along the flower's style until it reaches the ovule. After that, the sperm cells go through the pollen tube to fertilize the ovule's egg cell.

Therefore, pollen tube is the structure that allow sperm cells to move through the style.
