A virus infects a lung cell and begins replication. The lung cell releases interferon into the extracellular environment where it can be picked up by other nearby cells. As a result, the other nearby cells slow down their protein-making machinery to slow down viral replication should they become infected. This is an example of what kind of communication
Answer: The options are not given but it is gotten from another websites and here are the options.
A.Cell-to-cell (membrane molecule) recognition
B. Cell junctions
C. Paracrine signaling
d. Synaptic signaling
The correct option is C.
Paracrine signaling.
Explanation:
This is because in paracrine signaling cell communicate with other near by cells through chemical Messengers. It is a form of cell to cell communication in which a cell produced signal and transfer it to other neighbouring cells whereby the neighbouring cells alter or change their behavior to counter the effect of the signal. From the question, the lung cells send signals to neighbouring cells and this alter their behavior by slowering down protein making machinery.

Kahlia was given antibiotics and told to rest. Bored by spending all day resting, Kahlia decided to learn more about her respiratory system. Select all statements that are true of the respiratory system.
a. Both the alveolar wall and capillary wall contribute to the respiratory membrane.
b. All structures of the respiratory system have cilia to move mucus.
c. Mucus-secreting cells are found throughout the structures of the conducting and respiratory zone.
d. The alveoli have a simple squamous epithelium to allow for diffusion of oxygen and carbon dioxide across the respiratory membrane.
e. All structures of the conducting and respiratory zone are lined by a serous membrane.
Answer:
The correct statements are: A and D.
Explanation:
a. Both the alveolar wall and capillary wall contribute to the respiratory membrane.
The respiratory membrane is a more or less homogeneous surface composed of a set of structures that gases must cross between the alveolus and the pulmonary capillary. When blood reaches the lungs it has a high CO2 content and a low O2 content. O2 passes by diffusion through the alveolar walls and capillaries into the blood. There it is transported by hemoglobin, which will take it to the cells of the body where, by the same diffusion process, it will pass inside them for later use.
d. The alveoli have a simple squamous epithelium to allow for diffusion of oxygen and carbon dioxide across the respiratory membrane.
The function of the lungs is to carry out the gas exchange with the blood, for this the alveoli are in close contact with the capillaries. The simple flat squamous epithelium lines the alveoli of the lungs, they are flattened and irregular cells in a single cell layer that allow the easy diffusion of water, gases and other substances. In the alveoli there is the passage of oxygen from the air to the blood and the passage of carbon dioxide from the blood to the air.

Explanation:
analyze potential impacts of oceans on human populations as the result of climate change in the current century.
Answer:
The result of climate change is ocean levels increasing because of the increase in temperature. Ice is melting due to climate change and this is causing the ocean levels to rise rapidly. If the ocean levels rise above land, some villages/towns/cities could flood. As a result houses of which people live in and other structures may be destroyed. Water sources may also be contaminated, making the water unsafe for humans to consume.
The allele for a widow's peak hairline (W) is dominant, and the allele for a straight
hairline (w) is recessive. If both parents are heterozygous (Ww) for this trait, what is the
probability that their child will have a straight hairline?
I don't like using W instead we can try to use R 'kay?
R - Dominant
r - Recessive
75% chance that they will have widows peakline children. 25% chance for straight hairline

How is the food you choose to eat used to create energy? referring to cellular respiration
Answer:
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Can the ecosystem survive without light? Why or why not?
Answer:
No
Explanation:
Because plants prepare their food form photosynthesis and sun light is basic element for that process to take place. So without sunkight the plants would die and due to their extinction herbivorous animals would die eventually and then the other animals depending upon herbivorous will also die due dissapearence of their food

This group of Bacteria can be pathogenic, ubiquitous in the environment whose cell walls are composed of peptidoglycan. So, the correct options are C, D and E.
What is Bacteria?
Bacteria are defined as ubiquitous, mostly free-living organisms that contain a single biological cell that constitute a large domain of prokaryotic microorganisms. Bacteria are a few micrometers in length that were among the first life forms to appear on Earth, and are present in most of its habitats.
Some bacteria are harmful that serve a useful purpose that support many forms of life, both plant and animal, and are used in industrial and medicinal processes. This group A mentioned in the above example of Bacteria can be pathogenic, ubiquitous in the environment whose cell walls are composed of peptidoglycan.

Explanation:
In normal cells, stathmin is inactivated by phosphorylation at the start of M phase. Phosphatases remove these phosphates as the cell transitions from M phase to G1. What enzyme is likely to be responsible for phosphorylating stathmin during M phase
Answer:
The enzyme that is responsible for this is the cyclin dependent kinase subunit of mpf
Explanation:
This enzyme is also known as cyclin dependent kinase subunit, CDKs. they are protein kinases and can function as cell cycle regulators. They have the power to modify different protein substrates that are useful for the progression of cell cycle. CDKs are inhibitors hence stathmin is inactivated by phosphorylation. They help to control cell divisions. DNA should not be damaged for cell to move from G₁ to the S phase.
The enzyme that is likely to be responsible for phosphorylating stathmin during M phase is the cyclin dependent kinase.
Cyclin-dependent kinases:
Cyclin-dependent kinases (CDKs) are protein kinases characterized by needing a separate subunit - a cyclin - that provides domains essential for enzymatic activity. CDKs play important roles in the control of cell division and modulate transcription in response to several extra- and intracellular cues. CDKs are inhibitors hence stathmin is inactivated by phosphorylation. They help to control cell divisions. DNA should not be damaged for cell to move from G₁ to the S phase.Full kinase activity requires an activating phosphorylation on a threonine adjacent to the CDK's active site.Learn more:

Indicate whether each of the following occurs mainly in G1 phase (G), S phase (S), or G2 phase (H) of the cell cycle. Your answer would be a four-letter string composed of letters G, S, and H only, e.g. HGSS. ( ) DNA helicase activation ( ) DNA helicase deposition on DNA at the replication origins ( ) ORC phosphorylation ( ) Licensing of replication origins
Answer:
the answer is S-G-S-G
Explanation:
DNA helicases are enzymes that catalyze the unwinding of the double DNA helix in order to form a replication fork at the origin of replication (i.e., the site where DNA replication starts). DNA replication occurs in a bi-directional manner by two replication forks that move in opposite directions in order to form a replication bubble. The origin of replication is formed during the transition from mitosis to G1 when they are licensed for the subsequent S phase. The origin recognition complex (ORC) is a DNA binding complex that binds to the origin of replication, whose function is to act as a scaffold for the assembly of initiation factors. ORC is phosphorylated during the beginning of the S phase in order to dissociate this complex from chromatin.
