Answer: ATP plays a critical role in the transport of macromolecules such as proteins and lipids into and out of the cell. The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient. Active transport mechanisms do just this, expending energy (often in the form of ATP) to maintain the right concentrations of ions and molecules in living cells. ... Primary active transport directly uses a source of chemical energy (e.g., ATP) to move molecules across a membrane against their gradient.
Hope this helps... stay safe and have a great weekend!!! plz mark brainliest if i am right...
The role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.
Active transport is the transport process where carrier proteins pick up specific molecules and take them through the cell membrane against the concentration gradient.
This transport requires cellular or metabolic energy which is available in the form of ATP molecules produced within the cell.ATP plays a critical role in the transport of macromolecules such as proteins, lipids, and ions into and out of the cell.The hydrolysis of ATP provides the required energy for active transport mechanisms to carry such molecules across a concentration gradient.Thus, the role of ATP in the process of active transport is - It provides the energy that cells need to move molecules against a concentration gradient.

how could a cell disease-causing bacteria get inside a cell without damaging the cell membrane
Answer: Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Some pathogens, however, have acquired the ability to survive and replicate within macrophages after they have been phagocytosed.
Explanation: This is my answer
Disease causing bacteria enters the host cells through phagocytosis.
Phagocytosis is the process used by the cells allow the disease causing bacteria enters the host cells. Phagocytosis is the process by which a cell use its plasma membrane to engulf large particle which can't enter through the holes of cell membrane.
Bacteria has a large size which can't be enter into the cell through semi-permeable membrane of the cell like glucose and water molecules so it enters the cell through phagocytosis so we can conclude that cell use phagocytosis in order to enter the cell.

A woman of childbearing years who is not pregnant has _______ absorption rate of calcium as compared to a woman who is pregnant
Answer:
The correct answer is - lower
Explanation:
Pregnant women require an increased amount of calcium as it can provide a sufficient amount of calcium for herself and her fetuses. During lactation, the calcium is reabsorbed very fast and rapidly that supplies the calcium for the milk. So, the normal women of childbearing age do not require the amount of calcium as pregnant women require.
Thus, there is a lower absorption rate of calcium as compared to a pregnant women

Suppose there was NO meiotic recombination but maternal and paternal chromsomes still assorted randomly during meiosis. How many different kids would be possible from two parents?
Answer:
8,324,608 chromosome combinations
Explanation:
During meiosis, chromosomes separate independently so that only one chromosome came from the father and the other homologous chromosome came from the mother. This process of independent assortment produces a huge amount of possible combinations in the diploid zygote cell. In humans, the haploid number of chromosomes is n = 23, thereby there are 2²³ = 8,324,608 chromosome combinations. Thus, the independent assortment of chromosomes during meiosis is a key factor that contributes to genetic variation in the offspring.

Question: Characteristics of styrofoam cup before placing it in water
Subject: Science
Styrofoam cups are utensils made of polystyrene foam that are used for drinking purposes. The physical properties of the cups before placing in water are firm and hard in shape.
What are physical characteristics?Physical characteristics are the properties that are not manifested by the chemical reactions and include the measurable and visible state, including conductivity, hardness, solubility, shape, malleability, melting points, color, etc.
Styrofoam cups are thermoplastic which allows them to remain solid at RT and liquid at the boiling point. They can be arranged and molded into various shapes and sizes according to the need.
The cups are stiffer and stronger before they are placed in water, but after they are placed in water they lose their firmness and become soft.
Therefore, the styrofoam cups are solids and a little firm before placing in water.
