Answer:
This question lack options, options are:
A. Mutation
B. Evolution
C. Heredity
D. Reproduction
The correct answer is B.
Explanation:
Evolution is essentially a process of genetic change over time, that is, it is the result of accumulated changes in the composition of the gene pool. Variation is the raw material of evolution. Without genetic variation, evolution is not possible. The ultimate source of all genetic variation is mutation. A mutation is a stable and inheritable change in genetic material. Mutations alter the DNA sequence and therefore introduce new variants. Many of these variants are usually eliminated, but occasionally some of these variants can be successful and incorporated into all individuals of the species. Mutation is a factor that increases genetic diversity. This is how evolution explains the origin of various life forms as a result of changes in their genetic load. The inheritance of these variations through offspring of parents who carry the variation, although the genetic endowment of a single organism is the same throughout life, the genetic makeup of a species, understood as a whole (genetic background), changes throughout from many periods of life. Mutations and variability, the product of natural DNA recombination, provide diversity in the genetic material of a species.

While viewing stained onion root tip cells you notice that distinct chromosomes cannot be observed in most of the cells. This is because most of the cells Group of answer choices
Answer:
This is because must of the cell must be in INTERPHASE.
Explanation:
The onion root tip is the growing part of the onion and many cells in it undergo mitosis. In the lab, it is prepared in a way that the cells become flat on the microscope slide so that you can observed them well.
In the cell cycle, most of the onions root tip cells are in interphase, they spend most of their life in interphase. In interphase, there is no observable changes in the celks, the cells keep on growing and the nucleus is been duplicated. This is because most of the onion root cells spend most of their time reproducing and growing in the interphase stage. During the interphase, the cells can still be seen in dark spots because the nucleus is still present and prophase has not started yet.

What are the characteristics of static electricity?
PLZZZZ HELPP!!
Explanation:
Static electricity is a form of electrical energy which is produced by the imbalance of positive and negative charge.
The characteristics of static electricity are:
1. The charges do not move and therefore called static in nature.
2. The charges of static electricity possess less energy, therefore, remain for a small period.
3. Static electricity is build up mostly on non- humid dry days.
4. The charge of static electricity does not generate electric fields but they are constant.
5. Due to a constant electric field, no magnetic field is generated.
6. The static electricity can be observed in the lightning, Van-de graff generator and xerox machines.

WILL GIVE BRAINLIEST Cohesion is most directly related to the ability of the plant to do which of the following? A. push sugar down towards the roots with gravity B. bend toward the source of light C. open and close the guard cells D. pull water up the stem against gravity
Answer:
D. pull water up the stem against gravity
Explanation:
Cohesion exists as hydrogen bonding exists between water molecules, which is the attraction of water molecules by the partially positive charge on the hydrogen and the partially negative charge on the oxygen. This allows water to stay connected as it travels up roots, combating gravity.

Using a series of arrows, draw the branched metabolic reaction pathway described by the following statements, and then answer the question at the end. Use red arrows and minus signs to indicate inhibition.
L can form either M or N.
M can form O.
O can form either P or R.
P can form Q.
R can form S.
O inhibits the reaction of L to form M.
Q inhibits the reaction of Oto form P.
S inhibits the reaction of O to form R.
Which reaction would prevail if both Q and S were present in the cell in high concentrations?
a. L → M
b. M → O
c. L → N
d. O → P
Answer:
1) The branched metabolic reaction pathway is attached.
2) The most prevalent reaction is L-->N
Explanation:
The reaction that eventually will prevail is the formation of the N molecule.
When Q and S are in high, they will inhibit the formation of P and R which are the molecules that form them. So, Eventually, there will not be P and R molecules, and hence, there will not be any more Q and S molecules.
L can still form equally M and N molecules. But as M forms O, and O inhibits M formation, with time, the higher O concentration is, the less M formation there will be.
On the other hand, N has no molecule that inhibits its production. So L turns to N formation, predominating this reaction.
The reaction that would prevail if both Q and S are present in the cell in high concentrations is L → N (Option c).
In a chemical reaction, a substrate is a molecule that reacts with a given enzyme to generate one or more products.In this case, L is the first substrate whose reaction produces N and M, while Q and S are the last products observed in this series of reactions.In turn, M acts as a substrate to form O as an intermediate, which subsequently serves as a substrate to form P and R.Finally, P serves as a substrate to form Q, while R serves as a substrate to form S.The series of chemical reactions are as follow:
L → N + M → O → P + R → Q + SIn this case, it is also important to remark that a given product of a chemical reaction can also inhibit the enzyme's activity (e.g., O is an intermediate that inhibits the formation of M).In consequence, the reaction that would prevail if both Q and S are present in the cell in high concentrations is L → N (Option c).

define the term overfishing in your own words. What would happen to the population of fish in the ocean if laws did not regulate overfishing? What would happen to the ocean eco-system?
Answer:
Overfishing is the level of excessive capture of marine animals.
Explanation:
Overfishing poses a great threat to marine biodiversity and ecological balance. The abundance of populations of large predators such as cod, tuna and swordfish has decreased by 90% due to overfishing. If we continue fishing at the current rate, scientists estimate that by 2048 any fish in the sea will have disappeared. Our seas are vulnerable and sensitive and a sudden and significant change in the number of individuals of a species can put great pressure on their ecological environment and a change in the balance of the oceans, and even in the food chain of other species.
Scientist set out to engineer a mutant version of LDH that would bind and reduce oxaloacetate rather than pyruvate. They made a single substitution, replacing Gln102 with an amino acid; the resulting enzyme should reduce oxaloacetate to malate. Which amino acid would be most effective at selecting the new substrate oxaloacetate
Answer:
Asparagine because it is an amino acid structurally similar to the Glutamine and both have the same charge (polar neutral).
Explanation:
Glutamine (Gln or Q) is an amino acid similar to the glutamic acid, with the exception that the carboxylic acid group is replaced by an amide. In addition, glutamine, serine, threonine and asparagine are polar neutral amino acids.
Asparagine and glutamine have a similar chemical structure due to both amino acids contain amide groups in the side chain (both are dicarboxylic amides), thereby a substitution involving these amino acids will have few deleterious effects on the resulting protein.
A conservative substitution is a replacement where the modification is produced by substituting amino acids with similar biochemical properties (in this case, polar neutral).

Consider the regulation of galactose metabolism through GAL4. Which of the following would result from a mutation that allowed GAL3 to bind to GAL80 in the absence of galactose?
A. There would be no change in the regulation of galactose metabolism because GAL3 normally binds to GAL80 to cause a conformation change in GAL80.
B. GAL80 would no longer be able to stimulate transcription of the genes involved in galactose metabolism.
C. GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.
D. Transcription of the genes involved in galactose metabolism would occur both in the presence and in the absence of galactose.
E. GAL4 would no longer be able to bind to the DNA thus, transcription of the genes involved in galactose metabolism would occur.
Answer: Option C.
GAL80 would be able to bind to GAL4, and transcription of the genes involved in galactose metabolism would be repressed.
Explanation:
Gal 3, Gal 80 and Gal 4 are form of proteins which participate in metabolism. They constitute a galactose-responsive switch for the GAL genes When galactose is absent, Gal 80 bind to Gal 4, masking the Gal4AD prevent gene transcription and prevents Gal4-mediated promoter activation

10. In the water cycle, liquid changes to gas by
O precipitation
O condensation
evaporation
O freezing
Answer:
evaporation
Explanation:
when the liquid heated for a long time it removes steam in form of gases
In the water cycle, liquid changes to gas by evaporation, which is in Option C. The water cycle, also known as the hydrological cycle, describes how water circulates through the Earth's ecosystems.
What is the water cycle?The water cycle involves a series of processes that include evaporation, condensation, precipitation, and infiltration. Evaporation is the process by which water changes from a liquid state to a gaseous state, such as water vapor. This occurs when energy (in the form of heat) is absorbed by the water, causing the water molecules to move faster and break free from their bonds to form a gas. After water evaporates, it can undergo condensation, which is the process by which water vapor changes back into liquid water.
Hence, in the water cycle, liquid changes to gas by evaporation, which is Option C.
