Answer:

A. codons, in groups of 3

Explanation:

The reason it is called a Frameshift mutation is because it alters the "reading frame" of the bases. The bases are normally read as codons, in groups of 3.

codons, in groups of 3. The reason it is called a Frameshift mutation is because it alters the "reading frame" of the bases. The bases are normally read as codons, in groups of 3.

Codons are units of genomic information made up of three nucleotides (trinucleotides) in DNA or RNA that code for a specific amino acid or indicate the end of protein synthesis (stop signals).

There are 64 distinct codons, of which 3 serve as stop signals and 61 identify amino acids.

The messenger RNA is made using the DNA as a template, which is subsequently used to create a particular protein. The bases that make up DNA and the associated messenger RNA are called bases. These nucleotides are frequently identified in RNA by the letters A, U, C, and G.

Therefore, Codons, in groups of 3. The reason it is called a Frameshift mutation is because it alters the "reading frame" of the bases. The bases are normally read as codons, in groups of 3.

The scientific mrthod is a process used by scientists to find answers to a question or to solve a problem. No there isn't just one because there are several versions of the scientific method. Some versions have more steps, while others may have only a few. Scientists can add steps, take out steps, revise, or make models.

The scientific method is a systematic approach used by scientists to investigate and understand the natural world.

It consists of a series of steps that guide the process of conducting scientific research and acquiring knowledge.

While there is a general framework for the scientific method, it is important to note that there is no single, universally accepted version of it.

The exact steps and emphasis may vary depending on the field of study, the specific research question, and the nature of the scientific inquiry.

Different branches of science may have their own specialized methodologies and techniques.

For example, the methods used in social sciences or qualitative research can differ significantly from those used in the natural sciences.

Thus, this is all about scientific methods.

Explanation:

In multicellular organisms, the body is a system of multiple, interacting subsystems. Subsystems are groups of cells that work together to form tissues. Interactions are limited to the circulatory, excretory, digestive, respiratory, muscular, and nervous systems.

Answer:

I. Divergent

II. Convergent

III. Transforming

Explanation:  

The crust is the outermost layer of the earth. It is divided into many plates that move over the mantle. Nowadays, there are six different bigger plates and twelve that are smaller. These plates are limited by three types of ridges or borders that differ in the movement they produce.

Boundaries types:

I. Divergent: New crust is created by the rising molten materials coming from the mantle. Two plates separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom. As old plates get separated, the new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates. This process occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. An example of this is the ridge located in the middle of the Atlantic Ocean, extending from Greenlander to the southernmost point of South America.

II. Convergent. Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one. In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices. The thicker and older plate subduces under the other plate. The Himalayas and Los Andes are examples of these collisions. Also, collisions create volcanic arches and continental arches.

III. Transforming. The plates slide laterally with each other, and they are usually called faults. It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate. No rocky material is either destroyed or formed. When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur. The movement breaks the crust and originates pronounced fractures. The San Andrés fault is an example of this plate ridges.

The kinds of boundaries that plates form is the fact that seismic activity takes place at the three known types of plate boundaries called divergent, convergent, and transform.

One converging plates often shift or move below the other, in  an act known as subduction.

The new magma (molten rock) tend to increase and may erupt to create volcanoes.

HIV viral load

HIV antibody levels

CD4 number

CD4:CD8 ratio

Explanation:

The doctor wants to check the current condition of HIV and its effects on the body of John and how are the medicines are helping. So he must be checking the viral load which means how much virus present in the blood. The level of antibodies gives the idea of antibodies produced by the body in response to infection with HIV.

The levels of CD4 cells are assessed as they are affected by the HIV virus along with CD8 cells. Antibodies are not produced against CD4 cells. Antibodies are generally for diagnosis only.

A. A change in the gene pool over time

Explanation:

The evolution is the change in the gene pool over time. Therefore, the option (A) is the correct answer.

Explanation:

Gene flow is the exchange of alleles between two or more populations.

Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur

A. Photosynthesis

Explanation:

Photosynthesis is a process almost every plant goes through. The goal of the process is the create glucose, a sugar that can be turned into energy. Photosynthesis consists of 2 cycles: light-dependent and light-independent (aka Calvin Cycle). Photosynthesis requires carbon dioxide, water, and sunlight. These reactants can then be transformed into glucose and oxygen. Photosynthesis is the basis of energy for all animals.

Answer:

A. Photosynthesis

Explanation:

Plants make their own food by the process know as photosynthesis.

Answer:  

During the relative refractory period, another action potential can be generated provided the stimulus is large enough.

Explanation:

The relative refractory period is the time after an action potential where the sodium channels are transitioning from inactivated channels to closed ones. In other words, voltage-gated Na+ channels have two gates, an external one and an internal one. During repolarization, the outer gate is blocking the entrance, and the internal one is open. So the channel is inactivated. When the inner gate is closed, the Na+ channel is closed.

During the relative refractory period, a second action potential can happen, but the stimulus has to be large enough to do it since the membrane is hyperpolarized, that is to say, the membrane potential is more negative than the resting action potential. The cell needs more Na+ ions to produce the second action potential.

Answer:

The rock cycle is a constant transformation of rocks between the three rock types of igneous, sedimentary, and metamorphic. If the sediments are buried behind other layers of sediment, they can lithify and form sedimentary rock. When rocks melt, magma is formed. Rocks form deep below the Earth, move and sometimes change, rise to the surface, and eventually return to their original location.

Answer: They are more likely to survive due to NATURAL SELECTION.

Explanation:

Adaptation of living organisms is the ability of these organisms to use its features which may by structural, physiological or behavioural to reproduce and survive in its environment.

NATURAL SELECTION plays an important role in the adaptation of organisms for survival. This is the process whereby the better fitted or adapted varieties of species in population are selected by environmental pressures. For example, a plant population in a region which had become drier climatically faces a water shortage problem not present previously. Among this plant population are a few individuals with a better developed root system and a thicker layer of cuticle. These individuals have a better chance of survival now because they can obtain a greater share of the limited water supply and reduce water loss from their surface more efficiently.

In the above example, the change to drier climate imposed an environmental pressure on the plant population. This affected the survival and reproduction of the individuals in the plant population in such a way that eventually a variety better adapted to the drier climate dominates the population.
