One extreme trait is favored:
Diversity decreases:
Diversity increases:
Answer:
Results in the evolution of the species: Directional selection
Results in new species: Disruptive selection
Favors traits at the two extremes: Disruptive selection
No increase in diversity: Directional selection
One extreme trait is favored: Directional selection
Diversity decreases: Stabilizing selection
Diversity increases: Disruptive selection
Explanation:
Directional selection which is also known as positive selection is known to be a mode of natural selection. In this type of selection, an extreme phenotype is favored over other phenotypes. This makes the allele frequency to move in the direction of that phenotype and this takes place over time.
Disruptive selection (known to be diversifying selection) talks about the certain changes in the population genetics whereby extreme values of a particular trait are favored over intermediate values. This results in new species.
While Stabilizing selection is a natural selection whereby there is a stabilization of the population mean on the particular value of a non-extreme trait. Here the diversity is decreases.
Answer: A) directional selection
B) disruptive selection
B) disruptive selection
A) directional selection
A) directional selection
C) stabilizing selection
B) disruptive selection

100 POINTS AND BRAINIEST FOR BEST COREECT ASNWER. Write a four-to-five sentence paragraph that explains how overexploitation contributes toward present-day mass extinctions. Provide a definition of the term overexploitation and at least one example with your answer.
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource. The term applies to natural resources such as: wild medicinal plants, grazing pastures, game animals, fish stocks, forests, and water aquifers.
Which solution has cells that are hypertonic?
Answer:
hypotonic solution
Explanation:
Answer:
Compared to fresh water, salt water is a hypertonic solution. This means that for cells to function, they must contain a cytosol that is a more hypertonic solution than salt water. Sea turtles, for example, live in a much more hypertonic solution compared to freshwater turtles.

Energy that is carried by electric current is what energy
Answer: electrical energy
The faster the charges move, the more electrical energy they carry. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy. Lightning, batteries and even electric eels are examples of electrical energy in action!Electrical energy can be either potential or kinetic energy since it's created from an electric charge flow. Continuing with the example of a battery, we know it has electrical potential energy while charging.

(_______) stars, however, will last for several billion years, because
they burn their fuel much more slowly. *
Answer:
Smaller
Explanation:
Life Cycle of a Star
Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.
Which statement describes the magnetic field inside a bar magnet?
a. It points from north to south.
b. it points from south to north.
c. it forms loops inside the magnet.
d. There is no field within the magnet.
The statement that describes the magnetic field inside a bar magnet is it points from south to north. The direction of the magnetic field lines outside is north pole to south pole.
What do you mean by the magnetic field?The magnetic field may be defined as the area around a magnet where a magnetic force is experienced.
The direction of the magnetic field is taken from the outward of the north pole and into the south pole of the magnet. The magnetic field lines begin near the north pole and extended towards the south pole of the magnet.
Therefore, the statement that describes the magnetic field inside a bar magnet is it points from north to south.

Why don't offspring always look like their parents?
A. The way offspring look also depends on their behavior traits.
B. The way offspring look also depends on the amount of nutrients received during birth.
C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.
D. The way offspring look depends on the combinations of alleles they inherit and on interactions between genes and the environment.
Answer: The answer is C. The way offspring look depends on the combinations of alleles they inherit and on interactions between traits and the environment.
Explanation: Each baby isn't an exact clone of the parents. They share different alleles from different parents. Think about it. If the dad and mother didn't look alike then how could the baby have the same physical features as both combined. So basically, The way offspring look depends on the combinations of alleles they inherit from their parents.

Como ha llevado la evolucion a que este insecto phyllium giganteumparezca una hoja segun la teoria de lamarck
Answer:
Due to adaptation of the environment.
Explanation:
Evolution has led this insect phyllium giganteum to appear like a leaf according to Lamarck's theory because this insect lives and feed on the leaf environment so in order to save itself from other predators it takes the shape and structure of leave in order to hide itself so this adaptation slowly transmitted from the parents to the offspring and as a result evolution occurs.

How does mRNA help in the differentiation of structures as an organism develops?
A. mRNA creates the amino acid chain that will eventually code for the specific protein that makes up a specific organ.
B.mRNA packages the proteins and takes them out of the cell
C.mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
D.mRNA is stored in the nucleus and carries the genetic code to make all of the specific structures of the body
Answer:
answer is part (C)
Explanation:
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ. Thus the correct option is C.
What is mRNA?
Messenger RNA is referred to as a type of single-stranded RNA which involved in protein synthesis. mRNA is made from a DNA template during the process of transcription (formation of protein from DNA to RNA).
The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery ribosome reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.

What’s the different properties of hbA and HbS
Answer:
The isoelectric point of normal HbA is 6.9 [91], but HbS has two fewer negative charges per hemoglobin molecule than HbA because glutamic acid residues in the β-chains of HbS were substituted by the valine residues [5], [6]. It shows that HbS has more hydrophobicity than HbA in this condition [10]
