Explain how the stomach Depends on other body systems to carry out its role in breaking down food molecules.

1 answer:

6 0

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

Answer:

The correct answer is -

1. right-handed

2. right-handed

3. positive

4. left-handed

5. negative

6. negative

Explanation:

In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.

If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.

f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix

atch the statement to the following options.A. One of a pair of chromosomes with similar genetic information and from different

Goryan [66]

Answer:

A. Homologue.

B. Chiasma.

C. Synaptonemal.

D. Synaptonemal.

E. Synapsis.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Matching the various terminologies in genetics with their description, we have;

A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.

C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.

D. Synaptonemal: four chromatids are held together by a zipper-like structure.

E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

True or False: The oxidation process occurring in the liver rids the bloodstream of 32% of the alcohol present.

murzikaleks [220]

Answer:

False

Explanation:

Oxidation process occurring in liver rids bloodstream of not 32% of alcohol present.

Once the alcohol enters the body, 5 percent of it is excreted in the form of the urine and another 5 percent is eliminated from the body by exhaling and the rest of the alcohol is converted to acetic acid by oxidation.

Thus,

Oxidation process occurring in liver rids bloodstream of 90% of alcohol present.

How are organisms that have alternating generations different from most plants and animals?

adelina 88 [10]

Answer:

plant organisms can alternate between diploid sporophyte and haploid gametophyte phases.

Explanation:

Once mature, the gametophyte produces male and female gametes. When haploid gametes unite, they form a diploid zygote. The zygote grows via mitosis to form a new diploid sporophyte,Thus unlike in animals.

A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to relea

lorasvet [3.4K]

A hormone released in the small intestine that stimulates the pancreas to release digestive enzymes and the gallbladder to release bile is known as Cholecystokinin.

Hormones play a huge position for your normal functioning. They manage heart rate, sleep cycles, sexual feature, and replica. Your metabolism, urge for food, growth and development, temper, strain, and body temperatures are all suffering from hormones.

Cholecystokinin is secreted by using cells of the upper small gut. Its secretion is stimulated by using the advent of hydrochloric acid, amino acids, or fatty acids into the belly or duodenum. Cholecystokinin stimulates the gallbladder to settlement and launch stored bile into the gut. Cholecystokinin (CCK) is produced more often than not inside the duodenum and the jejunum. The physiological roles of CCK are the stimulation of pancreatic secretion and the contraction of the gall-bladder. Secretin and CCK are peptide hormones secreted via the endocrine cells inside the gastrointestinal tract. Secretin stimulates the secretion of water and bicarbonate ions from the pancreas, while CCK stimulates the synthesis and secretion of bile juice and pancreatic enzymes.
