What challenges cell biologists face in the 21st century?
Answer:
There are many types of challenges are faced by the scientists in 21st century. some are as given below:
Explanation:
1. Getting biodiversity. We're losing species at a disturbing rate, and we have to comprehend what the implications of that may be.
2. sustainable development. Like feasible agriculture, yet more broad sense. Discovering approaches to accommodate human needs while limiting the mischief we cause to the earth is urgent.
3. Everything about hereditary qualities. It's simply so much fun.
4. The most effective method to cut across political, social, and social limits and spur enormous and little scope activity to lessen biodiversity loss. This point may have a hefty sociology component, yet it's significant. All the natural and biological information on the planet won't make any difference on the off chance that we can't get individuals to follow up on it.

By what factor (how much) does the milli- unit differ from the centi- unit?
earth science
Answer:
By a factor of 0.1.
Explanation:
Hello,
In this case, since the milli- unit has a factor 0.001 and the centi- unit a factor of 0.01 we can apply the following division in order to compute by what factor they actually differ from:
[tex]\frac{milli}{centi}= \frac{0.001}{0.01} =0.1[/tex]
It means that the milli- unit differ from the centi- unit by a factor of 0.1. Conversely, the centi- unit differ from the milli- unit by a factor of 10:
[tex]\frac{centi}{milli}= \frac{0.01}{0.001} =10[/tex]

Explain how passive and active transport are similar and how they are different.
Answer:
Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Explanation:
Answer:Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.
Explanation:
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane-bound carrier proteins is called
Answer:
Facilitated diffusion
Explanation
Generally when molecules undergo passive diffusion along their concentration gradient,and aided by the cell membrane which provide hydrophillic areas for the molecules to pass through,this is called facilitate the diffusion.The membrane would be impermeable to these molecules without the proteins,
It is a special transport mechanism for large molecular substances like glucose and Amino acids and ions e.g Na+ and K+.Therefore facilitated mean to aid,thus the membrane proteins aids or help molecules to pass through.
Channel protein and carrier proteins are the two type of protein involved in the transport.They are specific for each molecules,and would only allow the passage of one molecule or ion through.
Energy is not needed for this to occur place the molecules of glucose are moving along the concentration gradient.
Specifically channel proteins are fixed in shape,some are gated.They are water filled pores Carrier proteins are flexible and adjust their shape to the two media for transport.Thus if the concentration of substances to be transported i s higher on on side A of the cell membrane proteins,the carrier protein will be open to that side to convey the molecules across.
The amount of molecules transported depend on the amount of the carries and channel protein available.

This is a molecule of glucose, a simple carbohydrate. If this molecule were broken down, would it provide all of the elements needed to assemble lipids, nucleic acids, or proteins? Use evidence from the diagram in your answer.
Answer:
The correct answer is - no.
Explanation:
Carbohydrates are made up of thee elements carbon, hydrogen, and oxygen so if the carbohydrate is completely broken down it will release these elements.
Lipids are made up of similar elements as glucose however, they also contain sulfur and phosphorus. Similarly for proteins and nucleic acid nitrogen, nitrogen sulfur, and selenium other than the elements released by glucose.
Thus, the correct answer would be - no.

Certain kinds of shells are always found in rock layers lower than layers with plant fossils. Dinosaur fossils show up only in layers above or with plant fossils what does this tell you about When these organisms lived
Answer:
This shows that once animals were on the surface there were plants for them to eat.
Dinosaur fossils show up only in layers above or with plant fossils. This shows that dinosaurs were animals that lived with plants and feed on plants.
What are fossils?Fossils are the remains of plants, animals, and other substances that are preserved under the layers of rocks and earth. They are the preserved form that gives the knowledge of organism present in before times.
Dinosaurs lived 65 million years ago, but still, their bones and remains are found on earth. They were found with the fossils of plants, so this tells us that plants were also present at the time of their presence, and they fed on plants.
Thus, only strata above or in conjunction with plant fossils do dinosaur fossils appear. This demonstrates that dinosaurs were also plant-eating and lived with plants.

Answer:
B
Explanation:
. Name the cells that are produced by the testes and ovaries.
Answer and explanation:
In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.
what do you think the difference between simple and complex carbohydrates is?
Answer:
Complex carbohydrates are present in foods such as bread and pasta. Simple carbohydrates are in foods such as table sugar and syrups. Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy.

A cell membrane is very specific about what it allows across. How does t help the cell?
Answer:
Explanation:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] 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.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

Answer:
The correct answer is: option D. all of the above.
Explanation:
In sexual reproduction, two opposite gender gametes are fused together to form a zygote by the process called fertilization which forms the new organism that is genetically unique.
In diatoms, sexual reproduction caused various types of advantages such as higher or enhanced genetic variability as recombination occurs. It also helps the ability to responding to environmental change Increasing the population or species size and other.
Thus, the correct answer is: option D. all of the above.
The blood-brain barrier (BBB) is most permeable to which of the following?
A. Platelets, white blood cells and red blood cells.
B. Sodium, potassium and chloride.
C. Glucose and oxygen.
D. Antibiotics.
Answer:
C. Glucose and oxygen.
Explanation:
The blood-brain barrier is a composition of endothelial cells that regulate the entry of substances into the extracellular fluid found in the central nervous system. Their high degree of selective permeability ensures that no solutes can cross the barrier, and only the right substances which are crucial to the workings of the central nervous system can scale through.
Oxygen which is needed for the proper functioning of the central nervous system and which is hydrophobic in nature is allowed to pass the blood-brain barrier. Glucose too which is an important nutrient/macromolecule for brain health can also move through the blood-brain barrier.
