Answer:
The youngest crust (shown in red) is near mid ocean ridges and spreading zones. All three rock types in the earth's crust—igneous, sedimentary, and metamorphic—can also be recycled back to their original molten magma form. This process occurs when oceanic crust is pushed back into the mantle at subduction zones.

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
Answers
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.

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
Answers
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:

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.
Answers
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.

Water is transpired through stomata, but carbon dioxide also must pass through stomata into a leaf for photosynthesis to occur. There is evidence that the level of carbon dioxide in the atmosphere has not always been the same over the history of life on Earth. Explain how the presence of a higher or lower concentration of atmospheric carbon dioxide would impact the evolution of stomata density in plants.
Answers
Answer:
Escribir en español, por favor.?
During those high-carbon-dioxide times, plants that produce fewer stomata,
when carbon dioxide levels are low, plants need many stomata in order to scrape enough carbon dioxide to survive.
How does carbon dioxide affect water uptake?Plant water use, an increase in atmospheric CO2 means that stomata, or the pores on leaves that exchange gases between the leaf and the atmosphere, do not need to open.
Thus, carbon dioxide levels are low, need many stomata in order to scrape enough carbon dioxide to survive.

What is a density dependent limiting factor that affects population size?
-Drought
-Climate
-Natural Disasters
-Disease
Answers
Answer:
Disease
Explanation:
In Ecology, certain factors that affect the size of a population can either be dependent on size or not. Density-dependent factors are those factors that affect population of organisms in dependence of how dense the population is. Examples of these density dependent factors are diseases, predation etc.
For example, a certain disease will spread faster among a population of organisms whose size is dense but slower in a scarcely densed population. Hence, disease as a factor is dependent on population size. Note that; Drought, Climate, and Natural Disasters will wipe out a population irrespective of its size.
