Answer:
The cell membrane
Explanation:
One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.

When using enzyme-linked immunosorbent assay to determine relatedness of species, what parameter is used to determine results?
Answer:
The change of color in the sample wells with the color in a known sample
Explanation:
Enzyme-linked immunosorbent assay (ELISA) is a technique widely used in molecular biology laboratories to measure antibodies, antigens and/or proteins in the samples that are being analyzed. This assay uses antibodies and color changes in order to identify target substances. The ELISA assay is heterogeneous because the antibody or the antigen is immobilized in a solid support composed by wells of microtiter plates. This assay uses chromogenic reporters and substrates that produce color changes, thus evidencing the presence of antigens which can be species-specific.
How do triglycerides found in animals differ from those found in plants.
Answer:
Lipids include a diverse group of compounds that are largely nonpolar ... Lipids also provide insulation from the environment for plants and animals (Figure 3.3.1) . ... A fat may contain similar or different fatty acids attached to glycerol. ... If hydrogens are present in the same plane, it is referred to as a cis fat; ...
Explanation:
The triglycerides found in animals are solids while the triglycerides found in plants are generally liquids.
What do you mean by Triglycerides?Triglycerides may be defined as a type of ester that is considerably derived from glycerol and three fatty acids. They are the main constituents of body fat in humans and other vertebrates, as well as vegetable fat.
The Triglycerides that are found in animals are typically solid or semisolid. They have the same appearance and properties at room temperature and are classified as fats. Those triglycerides that are liquid are called oils and are derived chiefly from plants.
In animals, the carbon atoms in the fatty acids are saturated with hydrogen atoms. This permits them to lie straight and the molecules will pack neatly into a solid arrangement. In plants, missing hydrogen atoms cause kinks in the fatty acids which make the structure loosely compact, and thus they are liquids.
Therefore, the triglycerides found in animals are solids while the triglycerides found in plants are generally liquids.

Which trait is common to both science and pseudoscience? Both offer an explanation. Both are based on facts. Both are based on beliefs. Both change with time.
Answer:
Both change with time.
Explanation:
Scientific theory is based on complex methods of observation, deduction and experimentation. The resulting findings are usually tested and peer extensively peer-reviewed before being regarded as factual information. Science often changes with new data and experimentation.
Pseudoscience, uses relationships between data and observed phenomena to draw conclusions. This often involves compelling assumptions, and anecdotal data without the need for external review or validation.
Both may change over time, as society's approach to new information and phenomena evolve.
Answer:
B: Both are based on facts
Explanation:
Took the test, and looked it up.

Why do tigers have striped fur?
Answer:
to blend with their environment and not from predators but so there prey doesn't see them because tiger don't really have a natural predator except humans so prey would be the only reason it stripe would help with
Explanation:
RIP KING VON
Answer:
They have developed an effective camouflage. The pattern is actually part of the animal's skin so it appears below the fur as well. Tigers don't need protection from other animals, though they do need protection from human beings. The striped-coat camouflage serves to hide them from prey.

William is developing the model shown below to illustrate the process of photosynthesis. He plans to use the model to explain how photosynthesis transforms both energy and matter.
The diagram shows a chloroplast. In the light-dependent reactions, light strikes the thylakoids, water enters, and oxygen is released. In the light-independent reactions, carbon dioxide enters a cycle and sugars leave the cycle.
Earth systems include the biosphere, atmosphere, and geosphere. Use the model to explain how photosynthesis acts to transfer carbon between two Earth systems.
Answer:
The correct answer is - Photosynthesis takes carbon from the atmosphere and brings it to the geosphere and into plants.
Explanation:
Photosynthesis is the process that involves converting light energy to chemical energy stored in the form of sugars with the help of carbon dioxide and water as reactants.
The carbon is pulled from the atmosphere in the form of carbon dioxide for the process to the geosphere and then used by the plants (biosphere). In plants, it is trapped by the chlorophyll present in chloroplasts and water is entered in the light-dependent reaction and carbon dioxide is used in the light-independent reaction.

Which light produces the most glucose in the plant? (remember from the previous lesson that glucose is a food product (sugar) made during photosynthesis in a plant.) blue green yellow red
Answer:
The correct answer is - red light.
Explanation:
Plants absorbed white light best than any other light, however, red light is better light than other lights after the white light due to its long wavelength and the right amount of energy to excite or stimulate the electrons of the light center of the chlorophyll and transit to a higher energy level which increases the rate of photosynthesis.
Red light is a light with a longer wavelength which helps in radiate and heat the chlorophyll than its counterpart. A high rate of photosynthesis results in more glucose production.
Answer:
Red light

Group of answer choices:
whether or not there have been evening storms for several days in a row
the stage of the moon
lower abundance of butterflyfish that consume the larvae
Answer:
The stages of the moon
Explanation:
The term menstruation is related to the moon stages. Because of their coincidence in occurrence and in their duration time, people used to associate the feminine cycle to the moon cycle.
It is commonly said that the ovulation stage coincides with the full moon stage. In the same way, menstruation occurs when there is a new moon.
What really occurs is that the feminine period might or might not coincides with the moon cycle, and depends on each woman. But this is not a strict rule.
The duration of a woman´s cycle depends on every woman, on the raze, on the age, among many other factors. The fact that sometimes the feminine cycle coincides with the moon cycle, does not mean that the moon determines the cycle stages in a woman.

Which of the following can combine in a cell to convert a lower-energy molecule into a higher-energy molecule?
ADP + P + energy
ATP + P + energy
ADP + P
ATP + P
Answer:
The reaction that converts a lower-energy molecule into a higher-energy molecule is ADP + P + energy.
Explanation:
ATP is the molecule that provides energy to the cell. It possesses three phosphate groups, each of which is bound by high-energy bonds and the separation of a phosphate by hydrolysis of ATP is strongly exergonic. The energy released is used by the cell to perform its functions.
In order to form an ATP molecule, ADP is required to bind to a phosphate group, a process that requires energy to establish the P-O-P bond, so the reaction, which is reversible, would be:
ATP + H₂O ⇄ ADP + Pi + ↑energy
This is what allows to convert a lower-energy molecule into a higher-energy molecule and permits an ATP molecule to become the energy exchanger of living organisms.
Answer:
ADP+ P + energy

Islands like St. George Island and Dog Island are common along all coastlines in Florida (Merritt Island is another example). Identify the coastal feature that these islands represent and describe the formation process of these islands.
Answer:
These islands are barrier islands.
Explanation:
Barrier islands are islands in front of the mainland that separate part of the sea from the open sea. They lie parallel to the coast and have an elongated, narrow shape. On the sea side, dunes often shape the surface, on the land side they are flat. They were created by deposits of waves, currents and wind. Their formation requires a shallow coastal fore, a sufficiently large sediment store and a weak to moderate tidal range.
