Answer:
B. Constants
Explanation:
Constants are the factors that stay the same throughout the entire experiment no matter which group. The definition of a constant is "a situation or state of affairs that does not change." this furthers the point that constant is the correct answer because they don't change in the experiment.

Suppose a bacterial infection kills off most of the prey at point B on the graph. How would this affect the predator and prey growth curves on this computer model at point C? At point D?
If an infection kills most of the prey at a point ( B ) before the predators can get to the preys at point ( c ). The number of predators between points B and C will reduce due to the unavailability of prey to feed on.
Therefore at points C and D the amount of available predator will decrease while the number of available prey will gradually increase because of the scarcity of predators which would have negatively contributed to their growth just like the bacterial infection.
Hence we can conclude that The predator growth curve at point C and D will be ; Negative ( decreases ) while The prey growth curve at point C and D will be ; Positive ( Increases ).
Although the graph related to your question is missing but a general answer is provided above within the scope of the question .

Which of the following is not one of the four major groups of biomolecules found in living organisms? O carbohydrates O lipids O Phosphoric Acid O proteins
Answer:
Phosphoric Acid is not one of the major 4.
Explanation:
Phosphoric acid is not one of the four major groups of biomolecules found in living organisms. Thus, the correct option for this question is C.
What are Biomolecules?Biomolecules may be defined as those organic molecules which are significantly required in order for the survival of living organisms. This is because these molecules play essential functions like cell division, gradual development, morphogenesis, etc.
The four groups of biomolecules which are found in living organisms are Carbohydrates, lipids, proteins, and nucleic acids. Among which carbohydrates are energy-deriving biomolecules, proteins govern the structural and functional properties of the living cell.
Nucleic acids are responsible for the representation of genetic material and lipids are known for energy storage due to their large simple structure.
Therefore, phosphoric acid is not one of the four major groups of biomolecules found in living organisms. Thus, the correct option for this question is C.

B. Always perfect types
C. Do not have sterile parts
D. Being modified to be pollinated by different agents.
Please answer my question.
*Silly, Incomplete and/or Spam answers will be reported!*
Answer:
A
Explanation:
Vegetative reproduction is a type of asexual reproduction that results in new plant ... Plants have evolved different reproductive strategies for the continuation of their species. ... The flower is the reproductive organ of plants classified as angiosperms. External plant structures such as leaves, stems, roots, flowers, fruits, and seeds are known as plant organs. Vegetative parts include roots, stems, shoot buds, and leaves; they are not directly involved in sexual reproduction. So yes, flowers can be characterized as part of vegetative in means of reproduction of flowers

During what period of time did the most dramatic population growth?
Answer:
1950-1987
Explanation:
The fastest doubling of the world population happened between 1950 and 1987: a doubling from 2.5 to 5 billion people in just 37 years — the population doubled within a little more than one generation. This period was marked by a peak population growth of 2.1% in 1962.

why don’t the two girls look the same using those word choices ?
Answer:
The process of meiosis involves cell division in which results in 4 daughter cells. Each cell has half the number of chromosomes of the parent cell. Genes are what determine what each cell obtains. A unit of genes is transferred from a parent to offspring. In some cases they are spreaded equally among the eggs therefore creating identical twins. While in other cases they are not distributed in variation, creating fraternal twins.
The two girls in the images do not look identical due to there being two separate eggs that were fertilized by the sperm. Independent assortment causes genes to separate from each other when reproductive cells develop. Variation defines the difference between the DNA in two individuals. Crossing over happens when the exchange of genes between homologous chromosomes results in parental mixture to the offspring. When this occurs, the genes are uniquely developed between the two eggs.
As you can see, the methodology for the making of two non-identical twins posses a series of steps. A variation of features is created due to genes determined by independent assortment. Meiosis is what divides the cells into daughter cells for fertilization by the sperm. All of which was talked about holds a great purpose in the process.

A strand of DNA has these bases: AGC CAT GTA TAC
What is the complementary DNA strand?
A. ACG GAT CTA TAG
B. TCG GTA CAT ATG
C. TGC CTA GAT ATC
D. UCG CỦA CAU AUG
Answer: The answer is c
Explanation:
DNA replication is semiconservative and at such, complementary base-pairing ensures that if adeinine is found on one strand, thymine is found on the other, and if guanine is found in one strand, cytosine is found on the other. complementary base pairing also helps to hold the double helix together by the formation of hydrogen bonds.
The correct answer is (B) TCG GTA CAT ATG
What is DNA?DNA is a double helix structure with two strands entwined together having complementary base pairs one purine and another for pyrimidine. It has all the required information for protein synthesis.
What is complementary base-pairing?Adenine (A) and Thymine (T) are complementary base pairs and Cytosine (C) and Guanine (G) are also complementary base pairs.
Why other options are incorrect?The option A has adenine as first in the sequence which is not complementary to the one given in the question. The option B had second base pair is guanine which is not complementary to the sequence in questionIn the option D has Uracil as first base pair which is not a part of DNA strand. Uracil is present only in RNA.So, option B is correct with complete complementary sequence of the question.
