Answer: D.Corals become bleached as they expel algae with increased temperatures.
Explanation:
As ocean temperatures rise, it can stress coral polyps, that causes them to lose algae. As a result, there is "coral bleaching". It is called that because the algae gives coral its color. When all the algae is gone, the coral is white.
The bleaching of corals in the world, are due to the increase in sea temperatures, but to understand how this changes corals, we need to know that.....
Coral bleachingCoral bleaching is a serious ecological problem mainly related to the increase in ocean water temperature. This problem can occur transiently or fatally, killing the coral. In the bleaching phenomenon, the corals become translucent, making it possible to verify the calcium carbonate skeleton of these animals. This happens because of the expulsion of zooxanthellae algae or because of the loss of pigment from these algae, which live in a mutualistic association with the coral.
Question answerD.Corals become bleached as they expel algae with increased temperatures.with this information, we came to the conclusion that with the increase in sea water temperature, algae that are associated with corals are expelled.

Explanation:
What biomolecule is a cell with a lot of ribosomes attached to its rough endoplasmic reticulum probably specialized to manufacture?
Answer:Ribosomes are the cellular structures responsible for protein synthesis. When viewed through an electron microscope, ribosomes appear either as clusters (polyribosomes) or single, tiny dots that float freely in the cytoplasm. They may be attached to the cytoplasmic side of the plasma membrane or the cytoplasmic side of the endoplasmic reticulum and the outer membrane of the nuclear envelope. Electron microscopy has shown us that ribosomes, which are large complexes of protein and RNA, consist of two subunits, aptly called large and small (Figure 1). Ribosomes receive their “orders” for protein synthesis from the nucleus where the DNA is transcribed into messenger RNA (mRNA). The mRNA travels to the ribosomes, which translate the code provided by the sequence of the nitrogenous bases in the mRNA into a specific order of amino acids in a protein. Amino acids are the building blocks of proteins.
Because proteins synthesis is an essential function of all cells, ribosomes are found in practically every cell. Ribosomes are particularly abundant in cells that synthesize large amounts of protein. For example, the pancreas is responsible for creating several digestive enzymes and the cells that produce these enzymes contain many ribosomes. Thus, we see another example of form following function.
Mitochondria
Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule. ATP represents the short-term stored energy of the cell. Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients. In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product. In fact, the carbon dioxide that you exhale with every breath comes from the cellular reactions that produce carbon dioxide as a byproduct.
In keeping with our theme of form following function, it is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving. When your cells don’t get enough oxygen, they do not make a lot of ATP. Instead, the small amount of ATP they make in the absence of oxygen is accompanied by the production of lactic acid.
This transmission electron micrograph of a mitochondrion shows an oval outer membrane and an inner membrane with many folds called cristae. Inside the inner membrane is a space called the mitochondrial matrix.
Figure 2. This electron micrograph shows a mitochondrion as viewed with a transmission electron microscope. This organelle has an outer membrane and an inner membrane. The inner membrane contains folds, called cristae, which increase its surface area. The space between the two membranes is called the intermembrane space, and the space inside the inner membrane is called the mitochondrial matrix. ATP synthesis takes place on the inner membrane. (credit: modification of work by Matthew Britton; scale-bar data from Matt Russell)
Mitochondria are oval-shaped, double membrane organelles (Figure 2) that have their own DNA and ribosomes (we’ll talk about these later!). Each membrane is a phospholipid bilayer embedded with proteins. The inner layer has folds called cristae. The area surrounded by the folds is called the mitochondrial matrix. The cristae and the matrix have different roles in cellular respiration.
Peroxisomes
Peroxisomes are small, round organelles enclosed by single membranes. They carry out oxidation reactions that break down fatty acids and amino acids. They also detoxify many poisons that may enter the body. Many of these oxidation reactions release hydrogen peroxide, H2O2, which would be damaging to cells; however, when these reactions are confined to peroxisomes, enzymes safely break down the H2O2 into oxygen and water. For example, alcohol is detoxified by peroxisomes in liver cells. Glyoxysomes, which are specialized peroxisomes in plants, are responsible for converting stored fats into sugars.

Answer:
These enzymes work in two ways. Some are pre-replicative and search the DNA for nucleotides with unusual structures
Explanation:
This happened through a lateral transfer of genes.
We can arrive at this answer because:
Lateral gene transfer is a system for exchanging genetic material between unrelated bacteria.Bacteria are beings that reproduce without the exchange of genetic material, but in some cases, this can be done with the lateral transmission of genes.This transmission can be done through the process of conjugation, translation, or transformation.The result is that new bacteria are created with a mixture of genes from two unrelated bacteria.

a particularly active cell might contain large numbers of
(a) Identify the most likely mode of transport across the membrane for substance L. Explain how information provided helps determine the most likely mode of transport.
Active transport occurs against the electrochemical gradient. It needs energy to move molecules from the lower concentration side to the higher concentration side. The mode of transport is active transport.
-------------------------------------------------
There are three main different types of transport across the membrane
Simple diffusion ⇒ Does not need energy to occurFacilitated transport ⇒ Does not need energy to occurActive transport ⇒ Needs energy to occurActive transport is the transport of molecules that move against the electrochemical gradient, so it does need energy to happen.
Molecules move from the lower concentration side to the higher concentration side of the membrane.
Carrier proteins are in charge of active transport. The needed energy might proceed from the ATP molecules or the membrane's electric potential.
In the exposed example, a scientist wants to determine how substance L enters a cells in a culture.
The cells maintain a 120 mM intracellular concentration of substance L. Varying external concentrations of substance L (10 to 100 mM) in culture medium (Table 1).Table 1. Rate of entry of substance L into mammalian cells in culture
External concentration of substance(mM) Rate of entry of substance L
10 5%
20 25%
30 45%
40 65%
50 80%
60 90%
70 95%
80 100%
90 100%
100 100%
Now, we need to identify the most likely mode of transport across the membrane for substance L, and explain how information provided helps determine the most likely mode of transport.
We know that the intracellular concentration is 120mM.
As we can see, this concentration exceeds all of the culture media concentrations. Yet, the substance keep moving into the cell.
As the concentration inside the cell is always higher than the concentration outside, we can assume that this is not passive transport because the molecule transport is going against its concentration gradient.
Hence, the remaining option is active transport. And as said before, we can see it because the substance keeps crossing the membrane toward the cell interior despite its concentration being higher in the interior of the cell than in the exterior.

Facilitated diffusion uses -----------------to help aid some substances across the cell membrane.
Facilitated diffusion uses transport proteins to help aid some substances across the cell membrane.
Facilitated diffusion is a passive transport process that enables the movement of specific molecules across the cell membrane with the assistance of transport proteins. While simple diffusion allows small, non-polar molecules to pass directly through the lipid bilayer of the cell membrane, facilitated diffusion comes into play when larger molecules or molecules with charges need to cross.
Transport proteins act as gateways or channels in the cell membrane. They are selective and only allow specific molecules to pass through. There are two main types of transport proteins involved in facilitated diffusion: channel proteins and carrier proteins.
Channel Proteins: These proteins form pores or channels in the cell membrane, allowing certain molecules, such as ions or water, to pass through. Channel proteins are highly specific and only allow certain substances to cross.
Carrier Proteins: These proteins undergo a change in shape to "carry" molecules across the membrane. When a specific molecule binds to the carrier protein, it triggers a change in the protein's shape that transports the molecule across the membrane. Once the molecule is released on the other side, the carrier protein returns to its original shape.
Facilitated diffusion is a crucial process for maintaining the balance of ions and molecules inside and outside the cell. It's important for the transport of nutrients, ions, and other essential molecules that may be too large or polar to diffuse directly through the lipid bilayer. The involvement of transport proteins ensures that only specific substances are transported, preventing unwanted molecules from entering or leaving the cell. Overall, facilitated diffusion is a highly regulated process that contributes to the homeostasis of the cell and the overall functioning of the organism.

Answer:
the beta-gamma subunit to form an inactive trimeric protein.
Explanation:
When inactive, the alpha subunit of the G-protein is bound to a GDP molecule.
The guanine nucleotide-binding proteins (commonly called G proteins or GTPases) represent an evolutionarily conserved protein family that serves to switch on/off different signaling pathways within the cell.G-proteins are composed of three different subunits: Gα, Gβ, and Gγ subunits.When GDP is bound to Gα, this subunit remains bound to the Gβ subunit in order to form an inactive heterotrimeric protein.When GTP is bound to the G-protein, then Gα dissociates from the other subunits and triggers the activation of the G-protein.In conclusion, when inactive, the alpha subunit of the G-protein is bound to a GDP molecule.
