D. in the number of neutrons :)
Explanation:
An isotope is one of two or more forms of the same chemical element. Different isotopes of an element have the same number of protons in the nucleus, giving them the same atomic number, but a different number of neutrons giving each elemental isotope a different atomic weight.

The statement is true about prokaryotic cells - C) Prokaryotic cells don't have a nucleus
Prokaryotic cellsCells come in various shapes and sizes. Based on the presence of a nucleus or membrane-bound organelles, cells are broadly classified as Prokaryotic cells or Eukaryotic cells.
Prokaryotic cells lack both, a well-defined nucleus and membrane-bound cell organelles. Examples of prokaryotes are blue-green algae, bacteria, and mycoplasma.

what is four the terrestrial planets
Answers
Answer:
Explanation:
Terresterial comes from the greek work "terra", which means Earth. So when you hear the word "terresterial " think that it means "like Earth". More specifically, it means that a planet is SOLID, like the Earth is. So, to figure out the answer to your question, let's list the planets starting with the ones closest to the sun and work out way out toward deep space. We can also describe each planet a bit as we list them.
Mercury - Closest to the Sun and, because of that, its very hot here. A lot of the ground on this planet is lava made of molten metal which is a liquid BUT there is also solid ground so it is terresterial. ✓
Venus - 2nd closest to the Sun. There is ground here, so it's terresterial. ✓
Earth - 3rd closest to the sun. There is solid ground here too so... Terresterial ✓
Mars - Also Solid. Terresterial ✓
Jupiter - Jupiter is made of Gas. If you went there, there would be nothing solid to walk on, but instead simply pass through it like it was a cloud. Therefore it is NOT terresterial
Saturn - Also a "Gas Giant" plant. (They are called gas giants because these planets are huge! You could fit 764 planet Earths inside of Saturn and over 1300 Earths could fit inside Jupiter!) Gas = NOT terresterial
Uranus - Another Gas Giant. Not terresterial
Neptune - The last of the gas giant planets and the furthest from the Sun. Again, its made of gas so its... not terresterial!
If you have trouble remembering the order, try memorizing this:
"My - Very - Epic - Mother - Just - Served - Us - Nachos"
Mercury - Venus - Earth - Mars - Jupiter - Saturn - Uranus - Neptune
Let me know if you need any more help! I am a scientist at NASA and my research focuses on all the planets you're currently learning about! Im happy to help out where I can.
Plants are able to produce energy from sunlight through photosynthesis. How do the products of photosynthesis in plants benefit animals, who cannot produce energy from sunlight?
Answers
Answer:
They produce sugars in order to survive and grow. Animals eat plants and take advantage of the nutrients produced by the plants. They also breathe in the oxygen produced as a by-product of photosynthesis
Explanation:
Plants use the energy in sunlight, water, and carbon dioxide to produce sugars which are used to provide chemical energy to power cellular processes. These sugars are also stored as starches.
Animals cannot produce their own food, and instead, rely on plants and other animals as a food source to power their own processes. Animals eat plants and obtain the food that plants have produced by photosynthesis. This is mostly carbohydrates (sugars and starch) but also some fats, proteins, and vitamins.

Since the elephant’s diet consists of play material only, where would the elephant get the missing element needed to make collagen (or any protein)?
Answers
Answer:
The elephant is a herbivores animal and feeds on plant material that consist of cellulose. Collagen is a type of protein that is absent in plant material and only found in skin, tendons, bones and muscles. The elephant also requires collagen to replace or repair their skin cell in every 2 weeks.
As elephants are unable to consume meat that contains collagen, they get collagen or protein from the plant material only with the help of bacteria or enzymes present in its guts. The bacteria having enzymes that helps in the breakdown of cellulose and access the proteins, fat or sugar present in the plant cell.
Elephants get collagen and other proteins from the vegetables they consume.
We can arrive at this answer because:
Collagen is essential for the maintenance of the skin.However, collagen is found in large amounts in meat.Few vegetables have collagen and elephants only feed on vegetables.However, the demand for collagen in the elephants' body is met by feeding on vegetables rich in cellulose and vitamin C.When cellulose is digested and vitamin C is used in the body, collagen production is stimulated.

The diagram or illustration represents the mid-Atlantic ridge which is the zone of upwelling of magma. As the magma upwells it gets deposited on both sides. According to paleomagnetism the magma on both left and right sides leads to the creation of plate tectonics. Hence more close they form the more recent or younger rocks/plates as compared to those formed farther away near the continental mass.Thus the correct option is A.

The diagram shows molecules that a mitochondrion and produces during a cellular process. Which other molecules is a product of this process?
A. DNA
B. RNA
C. C6H1206 (glucose)
D. ATP
Answers
Answer:D
Explanation: DNA and RNA are held in the nucleus and have nothing to do with what is shown in the image which is the process of cellular respiration. What is fascinating is that the mitochondrion has its own DNA but it does not produce it in a cellular process. C is false because the mitochondrion takes in glucose so it will go alongside the pyruvate O2. So we can conclude that it produces ATP with H2O and CO2 during this process.
ATP molecule is also a product of the cellular process that occurs in the mitochondria.
MITOCHONDRIA:
The mitochondrion is a membrane bound organelle found in eukaryotic cells. The mitochondrion is regarded as the power house of a cell because it is the site of the cellular process that synthesizes energy for the cell.The cellular process that occurs in the mitochondria is called cellular respiration. Generally, cellular respiration breaks down glucose molecule in the presence of oxygen. The chemical equation is as follows:C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP (energy)
From the attached image, it can be seen that water (H20) and carbon dioxide (CO2) are products. However, ATP molecules is also synthesized during this cellular process. Therefore, ATP molecule is also a product of the cellular process that occurs in the mitochondria.Learn more: https://brainly.com/question/23126016?referrer=searchResults

The fluid-mosaic model of the cell membrane suggests that the membrane is primarily composed of proteins and lipids. Which of the following is a function of proteins in the cell membrane
A to read messenger RNA to assemble amino acids
B. to provide a hydrophilic head so that water can enter the cell
c. to package and sort molecules to be sent in vesicles
D to allow substances to cross the plasma membrane via active transport
Answers
Answer:
B
Explanation:
Protein as amino acids
The fluid Mosiac Model is a theory that explains the structure of the functional cell membranes. The model is characterized by the lipid bilayer, in which protein molecules are embedded.
The correct answer is:
Option B. to provide a hydrophilic head so that water can enter the cell
The functions of protein in the plasma membrane are:
1. The lipid bilayer is amphiphilic, such that they have a hydrophobic and a hydrophilic end.
2. Membrane proteins are involved in the transportation of ions, molecules, or other substances across the membrane.
3. The membrane protein is selectively permeable such that, the aquaporins are the family of proteins, which is involved in the flow of water inside and outside the cell.
Thus, the correct answer is Option B.
