Answer:

DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful.

Explanation:

Natural selection can cause gradual speciation changes.

It is the process through which populations of living organisms adapt and change to new environment conditions and pass these genes to next generations.

Answer:

The correct answer is - A. MHC I molecules

Explanation:

Major histocompatibility complexes (MHCs) are presented to different T cells to identify the antigen on the host or infected cell. There are two MHCs - class I and class II. The class I MHC presents to cytotoxic T cells while MHC II to helper T cells.

A cytotoxic T cell only binds to the infected cell displays the foreign antigen such as viruses on the infected cell surface in order to recognize and kill the cells.

If any appropriate enzyme will be added to the solution, then the reaction rate will increase. The correct option is A.

The reaction rate or rate of reaction is the rate at which a chemical reaction occurs, defined as proportional to the increase in product concentration per unit time and the decrease in reactant concentration per unit time.

The rate of a reaction is an extremely useful diagnostic tool. We can improve production by learning how fast products are made and what causes reactions to slow down.

This information is required for the large-scale production of many chemicals, such as fertilizers, drugs, and household cleaning products.

The reaction rate will increase if an appropriate enzyme is added to the solution.

Thus, the correct option is A.

Answer:

Photosynthesis is the process by which plants take sunlight, carbon dioxide, and water to produce more complex molecules such as glucose and oxygen. This process is carried out cellularly in the chloroplasts. Chloroplasts are formed by thylakoid membranes where pigments such as chlorophyll are found. Chlorophyll is the pigment that captures the photons of light and activates the entire photosynthetic system through the excitation of an electron.

Answer:

Photosynthesis occurs in the chloroplasts.

Chloroplasts capture light energy.

Thylakoids can be found inside chloroplasts, where light-dependent reactions occur.

Chlorophyll is found in the thylakoids.

Chlorophyll absorbs light energy.

Chlorophyll is what makes plants look green.

Answer:

The correct answer is option A "D. SP2 3 trigonal Planar"

Explanation:

At the point when particles are bound together in an atom, the wave functions join to deliver new numerical depictions that have various shapes. This cycle of consolidating the wave functions for nuclear orbitals is called hybridization and is mathematically refined by the linear mix of nuclear orbitals.

The valence orbitals of a focal atom encompassed by three areas of electron thickness comprise of a set of three sp2 crossover orbitals and one unhybridized p orbital. This course of action results from sp2 hybridization, the blending of one s orbital and two p orbitals to deliver three indistinguishable hybrid orbitals situated in a tigonal planar geometry.

Answer:D

Explanation: A isn't right because during asexual reproduction there is no exchange of genetic characteristics thus the offsprings retain the genetic characteristics of their parents and there is no diversity.

Sexual reproduction on the other hand involves the fusion of gametes and the exchange of genetic characteristics thus the offsprings are diverse and are not identical to their parents as is the contrary in asexual reproduction.

Sexual reproduction produces organisms that are genetically diverse.

Sexual reproduction involves the combination of chromosomes from both parents. This combination of chromosomes introduces variation into the population. This combination does not occur in asexual reproduction.

Hence, the statement that correctly states why one type of reproduction is beneficial over the  other is that sexual reproduction produces organisms that are genetically diverse.

Explanation:

Savannah grassland biome is found in an area with an average precipitation of 76.2-101.6 cm. Therefore, option B is correct.

A region of grassland with scattered trees or groups of trees is how the savanna biome is frequently defined.

The savanna is a dry environment, making it difficult for tall plants like trees to flourish. The trees and grasses that thrive on the savanna have adapted to the dry climate and limited water supply.

In regions with savanna growth, a tropical wet and dry climate is prevalent. The annual precipitation averages between 30 and 50 inches, while the mean monthly temperatures are at or above 64 degrees Fahrenheit. Less than 4 inches are received per month during the dry season for at least five months out of the year. Hence, option B is correct.

supports the plant

makes up the majority of a plant

Explanation:

Ground tissues are one of the three types of plant tissues (others being dermal and vascular). They are composed of cells as follows: parenchyma, collenchyma, and sclerenchyma. These three cells that make up the ground tissues perform different functions in the plant cell.

- Parenchyma functions in photosynthesis and storage of extra food (carbohydrates) in the cell.

- Collenchyma functions in the support of young regions of the plant

- Sclerenchyma, which has the thickest cell wall, functions mainly in the strengthening/support of the plant cell.

Also, among the three tissue types in a plant, ground tissues make up majority of the plant cell.
