Answer:

stomach

Explanation:

During digestion, muscles push food from the upper part of your stomach to the lower part. This is where the real action begins. This is where digestive juices and enzymes break down the food that you chewed and swallowed.

Answer:

mouth

Explanation:

The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

Using established recombinant DNA technology, you insert a gene from a human liver cell into a bacterium. The bacterium then expresses a protein corresponding to the inserted DNA. To your dismay, you discover that the protein produced is useless and is found to contain many more amino acids than does the protein made by the eukaryotic cell.
Assuming there is no mutation in the human gene, explain why this happened.
a. bacteria do not use splicing to edit RNA after its transcription.
b. rRNAs in bacterial cells contain more nucleotides than in eukaryotic cells.
c. bacterial RNA contains less stop codons.
d. amino acids in bacterial cells are specified by double codes.

Answers

Answer:

The fact that the amino acid chain is consistently having more amino acids than what is actually present can be attested to the fact of how gene expressions can be observed in the prokaryotic cell compared to the eukaryotic one.

Which of these transport processes is the major means by which Na+ is transported across the membrane of neurons? Why?

A) both II and III because the activity of the neuron varies
B) I because Na+ is so small it can freely diffuse into the cell
C) III because Na+ is actively transported out of a neuron to maintain extracellular concentration
D) II because Na+ is charged and cannot cross the hydrophobic interior space of the cell membrane

Answers

Answer:

i think it’s C

Explanation:

I. is diffusion

II. is facilitated diffusion

III. is active transport

the third diagram makes most sense to me

Transport processes is the major means by which Na+ is transported across the membrane of neurons,I because Na+ is so small it can freely diffuse into the cell.

If blood flow through the afferent arterioles increases:

a. the smooth muscle in the vessel walls stretches to accommodate.
b. the increased flow and the stretch stimulates further relaxation of the arteriolar wall, lessening blood pressure.
c. the stretch stimulates further relaxation of the arteriolar wall, lessening blood pressure.
d. stretch stimulates vasoconstriction to reduce the flow.
e. the smooth muscle in the vessel walls stretches to accommodate the increased flow.

Answers

Answer:

d. stretch stimulates vasoconstriction to reduce the flow.

Explanation:

Afferent arterioles are a network of blood vessels that supplies the kidneys with blood. They branch from the renal artery and are important in blood regulation.

Myogenic mechanism is used to regulate blood flow to the kidney.

When blood flow increases to the afferent aterioles the smooth muscles its wall stretches and contracts to resist the pressure. This reduces blood pressure.

When the pressure reduces the smooth muscles relax to allow more flow of blood.

Which population is most likely to have exponential growth?
O A. The dust mites living in a sofa that is often used and never
cleaned
B. The angelfish living in a coral reef where there are many sharks
C. The mice living in a meadow with plenty of predators and limited
food
D. The foxes living in a forest where they compete with other animals
for food

Answers

Answer:

A. The dust mites living in a sofa that is often used and never cleaned

Explanation:

Without the sofa being cleaned, the dust mites will never experience any predation or die off from humans and harsh cleaning chemicals. This will enable the population to increase exponentially, as opposed to the other options where the organisms are at risk for ample predation and starvation.

Exponential growth refers to the growth of organisms in an environment having unlimited resources. The organism grows exponentially or in a geometric fashion.

The dust mites living on the sofa that is often used and never cleaned.

The population has high chances of exponential growth will be:

1. Exponential growth is seen in the environment or surroundings where the resources are plentiful, and the number of organisms is dependent on those resources.

2. The dust mites living in the sofa that has never been cleaned will show exponential growth. Since the sofa is never cleaned, the mites have never faced any elimination by chemicals. The population will increase exponentially.

3. The other options have chances of competition, starvation, and predation that will not lead to the exponential growth of organisms.

Thus, the correct answer is Option A.

Dam.In all the history of scientific discovery there has never been, perhaps, so general, rapid, and dramatic an effect wrought on the scientific centres of Europe as has followed, in the past four weeks, upon an announcement made to the Wrzburg Physico-Medical Society, at their December meeting, by Professor William Konrad Rntgen, professor of physics at the Royal University of Wrzburg. The first news which reached London was by telegraph from Vienna to the effect that a Professor Rntgen, until then the possessor of only a local fame in the town mentioned, had discovered a new kind of light, which penetrated and photographed through everything. This news was received with a mild interest, some amusement, and much incredulity; and a week passed. Then, by mail and telegraph, came daily clear indications of the stir which the discovery was making in all the great line of universities between Vienna and Berlin. Then Rntgen's own report arrived, so cool, so business-like, and so truly scientific in character, that it left no doubt either of the truth or of the great importance of the preceding reports. . . .Exactly what kind of a force Professor Rntgen has discovered he does not know. As will be seen below, he declines to call it a new kind of light, or a new form of electricity. He has given it the name of the X rays.Which statement correctly describes how the central idea of this excerpt is developed?
