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.
The environmental cue that determines the night of gamete release during a particular month is:
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.
When animals feed off of land faster than the plants can regrow, the land is _______.
a.
below its carrying capacity
b.
forested
c.
overgrazed
d.
depleted
Answer:
C. Overgrazed
This is because there were too many animals on the land to feed, when there are to many animals grazing the same piece of land, it is called overgrazing.
Explanation:
When animals feed off the land faster than the plants can regrow, the land is called "overgrazed." Overgrazing is harmful for an ecosystem. It is caused by cows, goats, etc.
What is overgrazing?Grass is consumed by animals such as cows and goats. Due to overgrazing, the ecosystem is harmed. Due to overgrazing, the plantation of an area is affected. The plants cannot regrow early because they have been fed by animals. Due to the low plantation, it affects the ecosystem's rainfall.
Less transpiration by plants is the result of less rainfall. Hence, less precipitation is seen. The overgrazing causes soil erosion. Generally, soil is held by the roots of the plants. As plants are not there, soil can be easily erased by floods and other natural calamities. The soil erosion caused the land to become sterile. The crops won't grow on sterile land. The infiltration capacity of the soil is reduced.
Hence, the correct answer is "overgrazed." Option C is the correct answer.

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.

Examine a two-gene cross that follows simple Mendelian inheritance of freckles and eyebrow shape between a woman with genotype Mmpp and a man with genotype mmpp. How many phenotypes are possible in their offspring and in what ratio?
a. 4 phenotypes: 9:3:3:1
b. 2 phenotypes; 1:1
c. 3 phenotypes; 8:4:4
d. 3 phenotypes; 1:2:1
The number of possible phenotypes in the Mendelian cross would be 2 in the ratio 1:1.
Phenotypic ratiosFirst, let us look at the result of crossing the two genotypes Mmpp and mmpp.
Mmpp will give the gametes Mp, Mp, mp, and mp
mmpp will give the gametes mp, mp, mp, and mp
The two sets of gametes can thus be lined up on both axes of the Punnet's square as shown in the attached image.
Genotypes of the offspring: 8 Mmpp and 8 mmpp
Since the two genes follow a simple Mendelian inheritance pattern, the 2 genotypes automatically equate to 2 phenotypes in the ratio 1:1.
Hence, the correct option is b.

write a 5 sentence paragraph that describes the characteristics that all living things share
Answer:
Living things are derived from single units and show several characteristics such as growth respiration, response to stimuli, homeostasis, evolution, and reproduction.
Explanation:
The natural world comprises several biotic or living and abiotic, non-living factors. Cells, are considered the smallest unit capable of supporting life. All living, or biotic factors must be able to grow, carry out respiration- a process that produces energy, and reproduce (pass on genes). They also show some level of organization or complexity, and respond to stimuli. Additionally, living organisms exhibit homeostasis or control over their internal environment and evolve or change over time to adapt to their external environments.

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

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
