Answer:
Nitrogenous
Explanation:
Transfer RNA, also known as tRNA, is one of the three types of RNA. It is involved in the translation process. The shape of the tRNA allows it to be a very important component of the translation process.
The morphological structure of the tRNA is in such a way that a sequence of nitrogenous bases called ANTICODON attach to one of its ends while an amino acid is attached to the other end. This way the tRNA molecule is able to read the mRNA codon using its anticodons and carry the corresponding amino acids.
N.B; the anticodons are composed of three nitrogenous bases just like codons. Codons are complementary to anticodons.
Which is the best definition of directional selection?
a process by which two species can no longer reproduce
a process by which one of the extreme variations of a trait is favored
a process by which individuals with either extreme of a trait are favored
a process by which average individuals in a population are favored
Answer:
B. a process by which one of the extreme variations of a trait is favored
Explanation:
The graph for this type of selection looks sort of like a camel's hump. With that being said, the phenotype of a population experiencing directional selection goes from one extreme to the other. Reference the evolution of the peppered moth during the Industrial Age as an example.
Sincerely hope this helps! God bless!A process by which one of the extreme variations of a trait is favored best describes the directional selection. Therefore, option (B) is correct.
What do you mean by directional selection?Directional selection is a negative natural selection mode in which an extreme phenotype is preferred over other phenotypes, causing the allele frequency to shift over time in that phenotype's favor.
Fossil evidence suggests that while the size of European black bears decreased during interglacial periods of the ice ages, it increased during each glacial period. This is an example of directional selection. A further illustration is the size of a population of finches' beaks.
The behavioral trait in question experiences a concentration of increasing alleles in the line selected in the upward direction and a concentration of decreasing alleles in the line selected in the downward direction.

Explanation:
What is the elevation of point B
Answer: c. Point B has an elevation less than 2750 feet.
Explanation:
The lines drawn on the map are known as contour lines and they are used to measure elevation. Point B is on a river and rivers are only able to flow at a lower elevation than the area around them.
Point B is therefore lower than the area around it and as the closest contour line to it puts the area at an elevation of 2,750 feet, that must mean that Point B is lower than 2,750 feet.

What are wetlands?Wetlands are defined as areas where water either completely covers the soil or is present either at or near the surface of the soil throughout the entire year or for varying amounts of time at different times throughout the year, including during the growing season.
Our water is cleaned by wetlands because they filter out sediments, other pollutants, and even chemical contaminants. Additionally, wetland areas act as a filter for and a processing facility for excess nutrients that may run off from agricultural and development sites. Historically, people have referred to wetlands as "the kidneys of our watershed."

What can you tell about an igneous rock that has a coarse-texture?
A. It is a carbonate.
B. It probably formed in a volcanic eruption.
C. It is most likely formed underground.
D. It is extrusive.
Answer: It is most likely formed underground
An igneous rock that has a coarse texture is one that formed from slowly cooling magma deep within the Earth's crust, or from slowly cooling lava on the surface. The slow cooling allows large mineral crystals to grow, giving the rock a coarse, grainy texture.
What can the size and shape determine ?The size and shape of the mineral crystals within the rock can provide information about the rock's cooling history and the conditions under which it formed. Coarse-grained igneous rocks such as granite, gabbro, and diorite typically have crystals that are visible to the open eye, with sizes ranging from a few millimeters to several centimeters in diameter.
The composition of the rock can also be determined based on the types of minerals present in the coarse-grained texture. For example, if the rock contains primarily feldspar and quartz, it is likely a granite. If it contains mainly plagioclase feldspar and pyroxene, it is likely a gabbro.
Overall, the coarse texture of an igneous rock indicates that it cooled slowly over a long period, allowing mineral crystals to grow and form a visible grain structure. The size and composition of the crystals can provide clues about the rock's history and origin.

B. Human cells have cell walls and are unable to move.
C. Humans can reproduce asexually when under stress,
D. Animals and humans are both uni-cellular organisms.
Answer:
It's A
Explanation:

Humans are considered animals because as in animals zygotes after cell division turns into a blastula, hence option a is correct.
What are animals?More than any other species, humans are capable of learning new things. Indeed, the majority, but not fully, of what distinguishes us from other animals is anchored in language.
In addition, because we have a backbone, humans are considered to be members of the chordate animal phylum.
The zygote is split into the blastula after fertilization, three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.
Therefore, humans are classified as members of the primate order within the animal group and having the blastula stage, hence option a is correct.
