Answer:it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.
Explanation:
Answer:
The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.
Explanation:
Which phases of the cell cycle are included in interphase? Check all that apply.
G1 phase
S phase
G2 phase
mitosis
cell division
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.
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.

Why is nitrogen cycle regarded as a complete cycle?
GIVING BRAINLIEST!!!!What stage of cellular respiration uses the high-energy electrons from NADH and FADH2 to form ATP molecules?
Krebs cycle
Electron transport chain
Fermentation
Glycolysis
Answer:
The answer is B- Electron Transport Chain
Explanation:
All those molecules are oxidized back to NAD+ and FADH molecules and the resulting H+ gradient works the ATP synthase to make ATP.
Hope this helped :)
true or false: if molecules move from where there is less to where there is more , they move down the concentration gradient
Which type of microscope allows you to use two glass lenses to magnify an object while focusing light waves to produce a clear image?
Answer:
The electron microscope uses a beam of electrons and their wave-like characteristics to magnify an object's image, unlike the optical microscope that uses visible light to magnify images.
Explanation:
How are luminosity and magnitude related?
(In your own words)
Answer:
Luminosity is an intrinsic(natural) measurable property of a star independent of distance. The concept of magnitude, on the other hand, incorporates distance. The apparent magnitude is a measure of the diminishing(decrease) flux of light as a result of distance according to the inverse-square law.

Why does it hurt when you get kicked in the balls?
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.

What group of organisms are closely related to archaebacteria
Answer:
The Archaea, single-celled organisms that often live in extreme environments, had been put together with the Bacteria, but molecular evidence reveals that they are widely separated. The Archaea are probably more closely related to the Eukaryotes, the branch that includes humans and most other familiar organisms.

explain how matter behaves differently than energy in a ecosystem
Answer:
Energy and nutrients are passed around through the food chain, when one organism eats another organism. ... An example of energy flow in an ecosystem would begin with the autotrophs that take energy from the sun. Herbivores then feed on the autotrophs and change the energy from the plant into energy that they can use.

Describe the role of algae in marine biome
Which of the following describes the relationship between photosynthesis and cellular respiration?
A.Only animals carry out cellular respiration, only plants carry out photosynthesis
B.Photosynthesis releases energy from glucose and cellular respiration stores energy as glucose
C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide.
D.Photosynthesis requires oxygen and cellular respiration releases oxygen
Answer:
C.C.Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide
Photosynthesis requires carbon dioxide and cellular respiration releases carbon dioxide. Hence, option C is correct.
What is cellular respiration?The process through which organisms use oxygen to break down food molecules in order to get chemical energy for cellular processes is known as cellular respiration. The cells of animals, plants, and fungi, as well as those of algae and other protists, all engage in cellular respiration. It takes place in mitochondria and cytoplasm.
Cellular respiration serves the straightforward objective of giving cells the energy they require to function. Food would be completely useless if living beings couldn't obtain the energy they required from it.
Anaerobic (without oxygen) and aerobic (with oxygen) cellular respiration are both possible (without oxygen). During aerobic cellular respiration, glucose and oxygen combine to create ATP, which the cell can utilize. As byproducts, carbon dioxide and water are produced.

Answer:
The Golgi Apparatus
Explanation:
organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell
Answer:
golgi apparatus
Explanation:
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?
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).
