It needs to accept electrons from calcium to have a full outer shell.
Answer:
mark me brainlest
Explanation:
Calcium, Ca , is located in group 2 of the periodic table, which means that is has two electrons on its outermost shell. In order to have a complete octet, calcium must lose these two outermost electrons, also called valence electrons. Calcium will react with nonmetals to form ionic compounds.

What best describes the function of the cell membrane
Answer:
The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.

How does natural selection impact a population
Answer:
People who acquire advantageous features have a greater chance of surviving, whereas individuals who have less useful traits are weeded out by natural selection. The higher the diversity of characteristics in a population, the greater the population's chances of survival.
natural selection is basically where stronger and smarter organisms survive and adapt. when a species changes locations or something happens to their habitat, they have to adapt. those that cant adapt will die off.
give two characteristics of the endordermis of young root
Answer:
The endodermis is the central, innermost layer of cortex in land plants.The endodermis helps regulate the movement of water, ions and hormones into and out of the vascular system. It may also store starch, be involved in perception of gravity and protect the plant against toxins moving into the vascular system.

What happens to plant cells
when they are exposed to
distilled water?
When plant cells are exposed to distilled water, they undergo a process called osmosis. The cells gain water and the cell swells. Thus, option B is correct answer.
Osmosis takes place when plant cells are submerged in distilled water, which has a lower solute concentration than the cytoplasm of the cell. To balance solute concentrations, water molecules flow through the semipermeable cell membrane. The vacuole of the water that enters the cell enlarges and presses on the cell wall.
The cell becomes hard and inflated due to this internal pressure, also known as turgor pressure. However, excessive water intake might cause cytolysis, which is the process when cells explode. The plant's overall health and cell structure are supported by this natural process of osmosis and turgidity.

In a typical animal, mitosis produces _________, while meiosis produces____________.
In a typical animal, mitosis produces two identical daughter cells, while meiosis produces four unique daughter cells.
Meiosis is a type of cell division that involves the parent chromosome being halved and then divided again to form four unique daughter cells which have only one copy of chromosome from the parent.
This occurs in sex cells such as the sperm and egg cells.
Mitosis is also a type of cell division but occurs with the parent cells to form two identical daughter cells.
This type of cell division have produces the same number of chromosomes the parents have and occurs in cells of the body which undergoes growth or during replacement of worn-out tissues.

why is rna synthesis called transcription and protein synthesis called translation?
Answer:
They are all part of protein synthesis. But RNA synthesis is called transcription because it is the process of making mRNA from DNA. Protein synthesis is called translation because the transfer of mRNA(which was made in transcription) to amino acids creates a chain of those acids which create proteins.
Explanation:
Transcription: The process of making mRNA from DNA.
mRNA is a type of RNA. m stands for messenger. Synthesis means making so RNA synthesis literally means making RNA which is what the process of transcription does. Additionally for protein synthesis the word simply means making protein which is what is happening in the process.
In the central dogma process, the genetic material gets copied and forms proteins needed for cell structure and functioning.
Transcription is the process of forming RNA from deoxyribonucleic acid. The DNA gets transcribed into ribonucleic acid.
The DNA formed by replication further processes and forms mRNA which is a type of RNA.
The formation of proteins from RNA with the help of ribosomes is called Translation.
In this process, the mRNA and tRNA translate and assemble amino acids into protein chains of the polypeptide.
Therefore, RNA synthesis is called transcription and the synthesis of protein is called translation.

Could more people be supported by 20 acres of land if they ate only plants instead of both plants and animals
Answer:
no,if they ate only plants then animals would die
Yes, more humans could be sustained if they ate only plants instead of both plants and animals.
Energy Flow in Ecosystem:-If you consume plants directly, you need roughly 10 pounds of plants to gain a pound. It takes about 10 pounds of plants to make 1 pound of meat. Instead of feeding an animal, this meal might be consumed directly by a human. Yes, more humans could be sustained if the food was fed to an animal first. Humans require around 100 pounds of plants to gain one pound. When one creature feeds another and absorbs the energy-rich molecules from its prey's body, energy is transmitted between trophic levels. The length of food chains is, however, constrained by the inefficiency of these exchanges. In order to obtain the energy they require, animals must hunt or gather food, whereas plants may produce their own food by utilizing the sun's light energy. The small green structures found in the green portions of plants called chloroplasts are where this process, known as photosynthesis, occurs.Learn more about the Energy transfer in food chain with the help of the given link:

Through osmosis, water can freely pass the membrane from the most diluted side to the less diluted one. Option a. swell
What is osmosis?
Osmosis is the simple passive transport of water molecules that occurs when two dilutions of different concentrations -in this example, the interior of the cell and the beaker content- are separated by a semipermeable membrane.
The membrane allows the pass of water but not solute (glucose). Hence, water can move from the most diluted side to the less diluted one. In other words, water moves from the less concentrated side to the more concentrated side (conserning the solute).
According to this information, the interior of the cell is more concentrated and less diluted than its exterior. Hence, water will move from the extracellular space foward to the cell interior, and the cell will swell.
Option a. swell
