Answer: The options are not given, here are the options from another websites.
a.hydrophilic molecules would easily pass through the membrane.
B. hydrophobic molecules would be attracted to the membrane.
c. the membrane would be fluid at room temperature
d. the saturated triglycerides would not form a bilayer.
The correct options are b and d.
hydrophobic molecules would be attracted to the membrane.
the saturated triglycerides would not form a bilayer.
Explanation:
Triglycerides are substances that are comprises of a higher degree of saturated fatty acid chains in which carbons are connected or linked up by single bonds. Triglycerides are non polar hydrophobic molecules and are therefore attracted by hydrophobic interactions ( that is between water and hydrophobes). Triglycerides helpin maintenance of cell membranes by forming a lipid bilayer.

What kind of rock is most Karst topography found in?
A)Limestone
B) Slate
C) Sandstone
D) Granite
Answer:
limestone
Explanation:
Karst is most strongly developed in dense carbonate rock, such as limestone, that is thinly bedded and highly fractured. Karst is not typically well developed in chalk, because chalk is highly porous rather than dense, so the flow of groundwater is not concentrated along fractures.
Answer: answer is A Limestone

Explain why bacteria are most suitable for genetic engineering
Answer:
Bacteria were the first organisms to be genetically modified in the laboratory, due to the relative ease of modifying their chromosomes. This ease made them important tools for the creation of other GMOs.

Explanation:
Manatees and seals both share some phenotypic similarities that are adaptations to an aquatic environment. However, seals evolved from a bearlike carnivore and manatees evolved from a hoofed mammal. This example shows that __________.
a. evolution is not always unidirectional.
b. evolution can occur rapidly for one species while the other species stays relatively unchanged.
c. similarity is a good predictor of how long it has been since two species shared a common ancestor.
d. evolution is not always divergent.
They are about as different as a leopard and a cow.
Meaning both are mammals of roughly similar size, and sharing a vaguely similar habitat. That’s the end of similarities.
Seals are carnivorous and manatees are plant eaters, and taxonomically they are in different orders. Seals spend much of the time on land, while manatees are completely aquatic. Seals have thick layer of fat and are adapted to Arctic water, while manatees, despite their roly-poly appearance, have almost no fat and do not handle cold water well at all. Here is the closest a manatee ever gets to an iceberg.

The movement of molecules across a cell membrane using a membrane transport protein and cellular ATP energy, generally moving the molecules from a region of low to high concentration, is called facililated transport
Answer:
Active transport: moving against a gradient
To move substances against a concentration or electrochemical gradient, a cell must use energy. ... Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.

some sponges produce toxins that harm other sponges. What is the best explanation for why they do this?
Answer:
They produce toxins to help them claim physical space for which they compete with other sponges.
Explanation:
I took the test.
They produce toxins to help them claim physical space for which they compete with other sponges.
What are sponges?Sponge, any of the primitive multicellular aquatic animals that constitute the phylum Porifera.
There are also many biological reasons why sponges are much more toxic than most other marine invertebrates, related to evolutionary advantages of being toxic. They produce toxin to compete with other sponges.

A difference between a Class I and a Class II tRNA synthetase is (select all that apply):
a. the Class I synthetase reaction requires a transesterification reaction not necessary in the Class II reaction.
b. the Class I synthetase uses the 2' OH of the 3' end of the tRNA as a nucleophile and the Class II uses the 3' OH.
c. the Class I synthetase requires ATP as a cofactor and the Class II does not.
d. the Class II synthetases are typically monomeric, whereas the Class I enzymes frequently function as multimeric protein complexes.
Answer:
Option b is the correct answer.
Explanation:
The 2' OH of each 3' end of the tRNA is used as a nucleophile by Class I synthetase, whereas the 3' OH is used by Class II.
The Class I aminoacyl-tRNA synthetase attaches amino acids to the 2'-OH group of the tRNA's 3'-end ribose residue, whilst the Class II synthetase attaches amino acids only to the 3'-OH group of the tRNA's 3'-end ribose residue. Both Class I and Class II enzymes conduct the transesterification process and the need of ATP.
What we have is option d is incorrect because, Class I enzyme is typically monomeric, while the Class II enzyme is dimeric or multimeric in nature.
Infer: Parrotfish rely on corals for protection and shelter. Look at the parrotfish population over time. Why did the parrotfish population increase at first and then later decline?
Answer:
Lack of shelter.
Explanation:
Although I cannot see the graph of the population over time, I am assuming it was exponentially rising and then began to decline. This is because the parrotfish were able to populate only until the species ran out of shelter. Once it ran out of shelter, the exposed fish began to die due to predators or the environment.
It may also be because of the drastic decline of living coral reefs. As coral reefs die, so do livable habitats for the parrotfish. As a result, the parrotfish decrease in population as fewer corals are available for the fish to live in.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

Encasing the cell is a membrane with special gates, channels and pumps that let in or
force out selected molecules.
Answer:
The text is explaining a cell membrane.
Explanation:
A cell membrane is made up of a phospholipid bilayer that acts as a kind of "skin" for the cell. The membrane helps the cell maintain homeostasis and filter out harmful particles. Elements like oxygen are allowed to pass through via protein channels, which act as gates. Does this answer your question?
