Populations of organisms that exhibit a high degree of variation have a greater chance of survival than populations of organisms that show little variation. This statement is usually true. Thus, the correct option will be B.
What is variation in organisms?Variation can be defined as any kind of difference between the different individuals in a species or group of organisms of any type of species. Mutations are the ultimate source of genetic variation, however the mechanisms such as sexual reproduction and the genetic flow can also contribute to mutation as well.
Evolutionary processes are the processes which are based on the selection of variations in a species by environmental variables. These differences may result in higher than usual survival benefits for the individuals as a result of positive trait adoption in an organism, or they may contribute to the genetic drift. Hence, all the variations in an organism have an equal chance of survival.
Therefore, the correct option will be B.

You would MOST LIKELY find a savannah grassland biome in an area with
A)
50 cm of precipitation.
B)
100 cm of precipitation.
200 cm of precipitation.
D)
250 cm of precipitation.
Answer:
D
Explanation:
Savannah grassland biome is found in an area with an average precipitation of 76.2-101.6 cm. Therefore, option B is correct.
What is the savannah grassland biome?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.

Ground tissue
stores extra food
supports the plant
is found in plants and animals
Omakes up the majority of a plant
Dis responsible for photosynthesis
Answer:
stores extra food
is responsible for photosynthesis
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.
Cytotoxic T cells recognize and kill host cells infected by viruses. They recognize these cells by the foreign antigen displayed on the host cell’s:_________.
A. MHC I molecules
B. MHCII molecules
C. toll like receptors
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.

What will most likely happen if an appropriate enzyme is added to a chemical reaction
If any appropriate enzyme will be added to the solution, then the reaction rate will increase. The correct option is A.
What is reaction rate?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.

Explain the relationship between these terms. Photosynthesis, chlorophyll, thylakoids, and chloroplasts.
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.
