Answer:
A. Bees and Butterflies receive food while pollinating the flowers.
In an experiment, three plants of the same species were grown in each of six identical pots. The heights of the plants were measured when growth began. Each post was watered everyday with salt solutions of different concentrations. The data for the experiment are shown on the table
1.) state the effect of increasing the percent of salt in the solution used to water the plants on the average final height of the plants in groups A through D
2.) state one way diffusion was involved in the cause of death of the plants in groups E and F.
Answer:
See the answer below
Explanation:
1. The data from the experiment shows that as the percentage of salt in the solution used to water the plants increased, the growth rate of the plants decreased. As the percentage increased from A to D, the change between the average initial and the final heights decreased, meaning that an increase in the percentage of the salt in the solution used to water the plants had a negative impact on the growth rates of the plants.
2. Due to the solutions used to water the plants in groups E and F being more concentrated (hypertonic) to that of the cell sap of the plant, water molecules diffused out of the cell sap to the ambient solution. As time goes by, the plants lose too much water, become wilted, and died off eventually. Instead of water molecules to keep diffusing into the plants in order for them to grow, the reverse was occurring and this led to their death.

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.

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.

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.
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.

8. The atomic number of an element is
a) equal to the number of isotopes of that element
b) is equal to the number of protons in the nucleus of an atom of that element
c) is equal to the number of neutrons in the nucleus of an atom of that element
d) is equal to the number of particles that can be found in the nucleus of an atom of that
The correct answer is B) is equal to the number of protons in the nucleus of an atom of that element.
Explanation:
The atomic number, which is represented by the letter Z, refers to the number positively charged particles known as protons. This characteristic is key in chemistry and related areas because based on these features elements have different properties and are named. For example, an atom of nitrogen element always contains 7 protons, while one of the gold contains 79 protons. Moreover, this property is not related to the number of neutrons because atoms with the same atomic number might differ in the number of neutrons, which leads to isotopes of the same element.

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.

while mutation is random, natural selection is not. In your own words, explain how this is possible
Answer:
Mutation is a alteration in the DNA sequence in a gene during cell divison iwhere gene is coded mitakeny or due to the error. Mutatio is a random process as it can not be determind or known befor bthechange in sequence what gene or DNA would be effected by it or what genes would be transfer from the parents.
Natural selection is a process where some of the traits that are helpful in the surviving and increasing the number of individuals in a population and transfer from one generation to other according the adaption and change over the long timeline. Thus, it is not random and based on the traits that are helpful in a environment or for the survival of

B. The light energy is converted to a glucose molecule
C. The light energy is converted to green light, giving the leaf its color.
D. The light energy is distributed throughout the cell to be used by basic cell functions.
Answer:
B
Explanation:
A cannot be true as photosynthesis requires carbon dioxide and water and uses light energy to break bonds and form oxygen and glucose
C cannot be true as chloroplasts contain chlorophyll which gives the cell its green colour by not absorbing green wavelengths of white light
