Answer:
to provide a barrier to the movement of substances in and out of the cell
Explanation:
Lipid molecules in the plasma membrane form a lipid bilayer which creates a semi-permeable barrier between the inside and the outside of the cell. Water and small molecules can cross the membrane. Other large molecules like ions cannot.

The part whose main job is to direct a plant cell's activities by sending instructions to different parts of the cell is the nucleus. It directs the cell's activities in the plant and animal cells.
What is the short definition of a plant cell?
Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals. Nucleus part main job is to direct a plant cell's activities by sending instructions to different parts of the cell.
Therefore, The part whose main job is to direct a plant cell's activities by sending instructions to different parts of the cell is the nucleus. It directs the cell's activities in the plant and animal cells.

What is gained from each part of aerobic respiration?
Answer:
Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. ... This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

An apple farmer notices that two of his trees produce particularly sweet apples. The farmer thinks that these sweeter apples would sell very well andcould make him a lot of money. He uses a Q-tip to pollinate the flowers of the sweet apple tree with pollen from the other sweet apple tree's flowers. He then takes the seeds from the fruit that they produce and grows a new field of trees from them. Almost all of these new trees make very sweet apples like the first two trees did.
Answer:
It is a right method for making a variety.
Explanation:
This is the right method for making sweet apples variety because in apple, cross pollination occurs and for making a new variety self pollination is the best way to prevent impurities in making a new variety. Due to self pollination, the farmer gain the sweet apple variety which help them to make more money by selling these sweet apple because of its demand.

Which is the final electron acceptor in the electron transport chain of cellular respiration?
A.) NADH
B.) FADH2
C.) oxygen
D.) carbon dioxide
Answer:
Option C) Oxygen. Is your correct answer.
Explanation:
Here's a little explanation for you so you can see and read.
Answer and Explanation:
C. Oxygen
Because, the oxygen we inhale is the final electron acceptor in the electron transport chain and allows aerobic respiration to proceed, which is the most efficient pathway for harvesting energy in the form of ATP from food molecules. So, your answer would be C. Oxygen.

Structural and behavioral adaptations affect the reproductive success of plants and animals.
A. True
B. false
Structural and behavioral adaptations can indeed impact the reproductive success of plants and animals. Adaptations are traits or behaviors that help organisms survive and reproduce in their environment. The statement is true.
Structural adaptations refer to physical features or characteristics that organisms possess. For example, plants may develop specialized structures like flowers, fruits, or seed dispersal mechanisms that enhance their reproductive success. Animals may have specific anatomical features like camouflage, protective shells, or specialized reproductive organs that increase their chances of successful reproduction.
Behavioral adaptations, on the other hand, involve actions or behaviors that organisms exhibit. These behaviors can include courtship rituals, mating displays, migration patterns, or parental care. Such behaviors help attract mates, establish territories, protect offspring, and ensure the successful transfer of genetic material.
Therefore, the statement is true.

Answer:
C. It will decrease the percentages of almond and apple crops because lesser numbers of honey bees are available for pollination.
Explanation:
The decrease in honey bees population will affect the ecosystem by decreasing the percentages of almond and apple crops which will lead to lesser numbers of honey bees available for pollination. Almonds and apple crops rely on honey bee colonies for pollination. So, a decrease in the population of honey bees will have an adverse effect on the availability of the crops and food supply. For most variety of almonds, they do not wind pollinate but require cross-pollination in order to produce nut. Other crops that rely on honey bees are watermelon, cucumbers and cherries.

One major difference between prokaryotic and eukaryotic cells is
Group of answer choices
Prokaryotic cells are microscopic, eukaryotic cells are not
Prokaryotic cells have no nucleus, eukaryotic cells do
Prokaryotic cells do not contain DNA, eukaryotic cells do
Prokaryotic cells are more complex, eukaryotic cells are more simple
Answer:
Prokaryotic cells have no nucleus, whereas eukaryotic cells have DNA enclosed in a nucleus.
Explanation:
The major difference between prokaryotic and eukaryotic cells is -Prokaryotic cells have no nucleus, eukaryotic cells do.
Eukaryotic cells are one of the two types of cell types prokaryotic and eukaryotic. There are various structural and functional differences found in them.
Eukaryotic cells are different from prokaryotic cells as:
the presence of a nucleus that stores DNA surrounded by the nuclear membrane presence of membrane-bound organelles like chloroplast. cell wall may or may not be present cell division is either mitosis or meiosis Eukaryotic organisms have various ranges of organisms either multicellular or single-celled as well.Thus, The major difference between prokaryotic and eukaryotic cells is -Prokaryotic cells have no nucleus, eukaryotic cells do.
