Answer:

See the answer below

Explanation:

Evidence that shows that the illustration is an asexual method of reproduction:

1. New tubers were produced without any signs of flowering or fertilization

2. Parent plant was produced from a vegetative part ( a tuber).

All the new tubers would be genetically identical because they were produced without fertilization. They all developed from the division of some of the vegetative cells (mitosis) of the parent plant. Hence, they are not only genetically identical with themselves but also with the  old tuber that produced the parent plant.

The purpose of using a Punnett square in studying genetics is to determine the probability of an offspring having a particular genotype. Thus, the correct option for this question is D.

Punnett square may be defined as a type of table in which all of the possible outcomes for a genetic cross between two individuals with known genotypes are determined. It is named after Reginald C. Punnett, who proposed this approach in 1905.

In genetics, Punnett square is extremely utilized in order to predict the possible outcomes of two unknown genotypes. With the help of these genotypes, phenotypes of a specific set of alleles are also determined. The important concept of Punnett square is that it always determines the probability, not the exact number.

Therefore, to determine the probability of an offspring having a particular genotype is the purpose of using a Punnett square in studying genetics. Thus, the correct option for this question is D.

Humans are considered animals because as in animals zygotes after cell division turns into a blastula, hence option a is correct.

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.

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.

A process by which one of the extreme variations of a trait is favored best describes the directional selection. Therefore, option (B) is correct.

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.

the turnips have a model called Turnip's model that's why the turnips have been selectivity breed from field mustard.

Turnip is a type of root vegetables that belongs to the mustard family.

Turnips are ready to harvest 40 to 55 days after planting. If harvesting the leaves, they are ready when they reach four to six inches in height. If only harvesting the leaves, cut them from the plant when they reach the desired size, leaving one inch of leaves above the crown of the plant. More leaves will grow in their place.

Make me brainliest pls

The term that is used to describe the number of deer in a square kilometer of forest is population density.

Population density is a measure of how crowded or dispersed a population is in a particular area. It is calculated as the number of individuals of a particular species per unit of area, such as square kilometer or square mile. This measure helps to understand the concentration of individuals of a species in a given area. A high population density means there are more individuals of a species per unit area, whereas a low population density indicates fewer individuals in a given area.

Population density plays a crucial role in understanding and predicting the effects of population growth on the environment. High population density can lead to increased competition for resources such as food, water, and shelter, which can cause stress on the ecosystem. It can also lead to an increased risk of diseases and higher rates of pollution. In contrast, low population densities can lead to the extinction of species due to lack of genetic diversity and inbreeding. Understanding population density is important for conservation biology, urban planning, and resource management, among others.

Answer:

Explanation:

The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.    

Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.

To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.  

In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.

From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,

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.

Pollution specifically air pollution can cause acid. Gases such as sulphur (IV) oxide and Nitrogen (IV) oxide when they are released into the atmosphere and comes into contact with precipitation, that is rain water causes acid rain. Sulphurous acid and Nitric acid is formed thus the rain falls in acidic form.

Acid rain when it falls on the leaves of the flora (plants) causes removal of the green colouring matter (chlorophyll) thus making plants to be deficient of food. Food in plants is made my the process of photosynthesis, removal of chlorophyll in plants kills them due to lack of food.

Also when acid rain finds it's way into the water bodies through surface runoff, aquatic animals such as fishes die due to lack of favourable environment and oxygen deficiency in water. Acidity in the soil also kills important decomposers therefore soil aeration is altered.
