Stomata are pores in the leaves of plants that allow gases to enter and exit the cells.
During the sunniest part of the day, the leaves are most actively performing photosynthesis.
During this time, which gas do the stomata allow into the leaf cells?
Answers
Answer:
carbon dioxide
Explanation:
In most plants, the roots absorb water from the soil. The water travels up through the xylem, a specialized layer of cells. In some plants, the water is absorbed through the leaves, directly from the air. Carbon dioxide, an atmospheric gas, enters the leaf through the stomata, the tiny pores in the leaves (a stoma is a single pore).

The ionization energy of the elements increases as one moves up a given group because the electrons are held in lower-energy orbitals, closer to the nucleus and thus more tightly bound (harder to remove). Based on these two principles, the easiest element to ionize is francium and the hardest to ionize is helium.

Answer:
The first sign of trauma to the testicle or scrotum is most often severe pain. Pain around the testicle may also be due to infection or swelling of the epididymis ("epididymitis"). Because the epididymis has a very thin wall, it easily becomes red and swollen by infection or injury.

1)When a phosphate is transferred from ATP, it can phosphorylate another molecule. How could this assist in allowing a protein to transport molecules against their concentration gradient?
2)What is it about the structure of ATP that contributes to its ability to act as an energy currency?
Answers
Answer/Explanation:
1) When phosphate is transferred from ATP, (which forms ADP and releases energy) it can phosphorylate another molecule. When this molecule is phosphorylated. It could become "energized" as it enters a higher energy state.
In this higher energy state, the protein has the energy to transfer molecules against a concentration gradient, which is an active process (requires energy).
2) Adenosine triphosphate contains three phosphate groups. The phosphate bonds are high energy. When ATP is hydrolyzed (water is added), these high energy phosphate bonds are broken and energy is released. This forms adenosine diphosphate (ADP).
1) When a protein molecule is phosphorylated, it becomes activated or powered and enables it transport molecules against their concentration gradient.
2) The bond that holds phosphate bonds in ATP gives it the ability to act as an energy currency.
ADENOSINE TRIPHOSPHATE (ATP)
Adenosine triphosphate, commonly known as ATP, is the means by which energy is stored and released in the cells of biological organisms. ATP is structurally made up of a ribose sugar, an Adenine base and three phosphate groups. The phosphate groups are held together by a bond called phosphoanhydride bond. ATP stores energy when one phosphate molecule is added to ADP while it releases energy when one phosphate group is broken. This latter process is called PHOSPHORYLATION. The ability of ATP to lose and accept phosphate group in its structure makes it perform the role of an energy currency in the cell.However, when a phosphate group is added to a molecule e.g. a transport protein, it is said to be phosphorylated. This means it will become activated or powered up to perform the task of transporting molecules against their concentration gradient.Learn more: https://brainly.com/question/15585148?referrer=searchResults
Which phases of the cell cycle are included in interphase? Check all that apply.
G1 phase
S phase
G2 phase
mitosis
cell division
Answers
Answer:
Interphase is the longest stage of the cell cycle and can be divided into 3 phases: G1 phase, S phase, G2 phase. The newly formed cell matures during the G1 phase. If the cell is going to divide, it enters the S (synthesis) phase where the DNA is replicated and the G2 phase where more growth occurs.
The interface is the first phase of the cell cycle during which the cell grows to its adequate level to start the duplication of its genetic material, the phases included in interphase are:
G1 phase.The cell physically grows, duplicating its organelles and the proteins needed for subsequent stages.
S phase.A complete copy of the cell's DNA is synthesized, as well as a duplicate of the centrosome, which will help separate the DNA in later stages.
G2 phase.The cell grows even larger, generates new proteins and organelles, and prepares for mitosis, cell division.
Therefore, we can conclude that the interface comprises the G1-S-G2 stages, and during them it grows to its proper level to start the duplication of its genetic material.

Which is the following is true about saturated fats?
a. They are typically solids at room temperature.
b. They are generally the healthiest fats to consume.
c. They cannot be broken down by enzymes.
d. By definition, they always contain one or more double bonds.
Answers
The following is true about saturated fats: they are typically solids at room temperature, which is in Option A, as they have a high melting point due to the absence of double bonds in their fatty acid chain.
What are saturated fats?Saturated fats are a type of fat molecule that consists of long chains of fatty acids. These fatty acids are called "saturated" because they are fully "saturated" with hydrogen atoms, that is, there are no double bonds between the carbon atoms in the fatty acid chain. This results in a straight, rigid structure that allows these fats to pack tightly together, which is why they are usually solid at room temperature.
Hence, the following is true about saturated fats: they are typically solid at room temperature, which is in Option A.

Which of the following statements is true
about exocytosis?
a. Help intake large material into the cell
b. Form of active transport
C. Occurs without help of cell organelle
d. It does not require energy
Answers
Answer:
B. Form of active transport
The statement that is true about exocytosis is that it is a form of active transport. That is option B.
Exocytosis is a cellular process where by materials especially waste products of metabolism or ions are moved from inside the cell to the outside of it.
An active transport is a process where by cells use energy to transport molecules across the cellular membrane.
There are different forms of active transport include:
EndocytosisexocytosisSodium Potassium Pump.Phagocytosis is the process by which cells transport large material into the, therefore Option A is False.
Golgi apparatus helps in exocytosis therefore option C is false.
Exocytosis requires energy, there option D is false
From the different forms of exocytosis listed above, exocytosis is a form of active transport because it makes use of energy.
