Explanation:

Answer: Transfer RNAs are coded by a number of genes, and are usually short molecules, between 70-90 nucleotides (5 nm) in length. The two most important parts of a tRNA are its anticodon and the terminal 3’ hydroxyl group, which can form an ester linkage with an amino acid.

Answer:

Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins? or other molecules, it is called gene expression

Explanation:

DNA makes genetic expression. DNA is a structure located in the nucleus that makes people themselves. DNA is unique to everyone, no two people are exactly the same. The way the DNA is structured and what instructions it was given affect one's genetic makeup.

Competition is the kind of relationship these two leaf eating species of

animals will have.

Competition involves organisms vying for resources such as food, sunlight,

space etc in the ecosystem. The two leaf eating animal species are in

competition with each other for plant leaves.

When drought occurs and the leaves reduces, competition for food

increases in which the fittest survive and the less fit ones die from starvation.

A mouse population that is originally white in color becoming darker in color after several generations is an example of natural selection.

Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways.

Eustachian Tube

Explanation:

Eustachian tube is the structure that connects the throat to middle ear. It performs an important role in the balancing of air pressure across the both sides and prevent from fluids building up in the ear.

The thing which is common between these two pictures is:

From the given image, we can see that there is image of ear and mouth and we can see that the outer ear is visible, while the mouth is wide open and we can see the interiors.

With this in mind, we can see that the Eustachian Tube is the structure which links the throat and ear and this performs the important function of regulating the air pressure that gets into the organs.

The most abundant in the body is cells.

Cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.

Moreover, they provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.

There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular). Prokaryotic cells don't contain a nucleus.

its one of those question you do flashcards for.

Answer:

Sex Cells have 1 set of chromosomes while Body Cells have 2 sets of chromosomes  

Meiosis reduces chromosome number so that sex cells (eggs and sperm) have a half set of chromosomes–one homolog of each pair. This is the haploid number.

Explanation:

Symaptric speciation is the formation of new species in populations that live in the same geographic area, while allopatric speciation occurs when the population is separated by a geographcial area. So, according to this: The difference between the sympatric speciation and the allopatric speciation is that sympatric speciation involves a behavioral barrier, while allopatric speciation involves a physical barrier.

there both the same so im going to be going for B, B is the correct answer.

The mother's genotype is denoted by Dd. Therefore, option (B) is correct answer.

Hereditary characteristics can be either dominant or recessive, as is the case with humans . Chromosome 5 is thought to be the location of the dominant gene responsible for the inheritance of cheek dimples, while chromosome 16 is thought to be the location of the dominant gene responsible for the inheritance of chin dimples.

It is generally accepted that dimples are caused by a dominant genetic feature, which indicates that the presence of only one mutated copy of a gene in each cell is required to produce the trait. On the other hand, there are academics who argue that there is no evidence to support the theory that dimples are inherited.

In parallel play children play independently among other children. In pretend play children act out any event of daily life and practice the roles and identities as established in their surroundings. In associative play children play together and are engaged in a similar or identical activity.

The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.

Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.

Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.

With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.
