Answer:
They do not make their own membranes.
They have, at most, one or a few enzymes.
They do not have both DNA and RNA.
They do not have cytoplasm or ribosomes.
They are much smaller than most cells.
They cannot replicate on their own.
Explanation:
Viruses are obligate parasites and are considered acellular since they do not have the basic cell structure. Being an acellular structure, viruses lack membranes, organelles, ribosomes, cytoplasm, etc. Viruses lack their own metabolic machinery, that is, they do not have their own enzymes to replicate themselves. They enter the host cells and use the enzymes of host cells to replicate themselves. Viruses have a genome (either DNA or RNA) that is surrounded by a protein coat.
On the other hand, cells are much larger than viruses. Cells have a cell membrane that encloses liquid cytosol in which various organelles such as ribosomes are suspended. Cells have all the required enzymes for metabolism and can make their own membranes. They can replicate themselves. DNA in a cell is present in the nucleus while RNA is present in both nucleus and cytoplasm.

Answer:
This can lead to ketosis. The latter condition can lead to death.
Explanation:
As a result of low blood glucose from low CHO diet, other food substances are converted to glucose. The process is called Gluconeogenesis. Fatty acid is usually converted to glucose, with the accumulation of ketone bodies in the blood, due to rapid conversion by the liver. This is known as Ketosis. But the acid -base homeostasis of the body is intact. It a condition that occurs during fasting, starvation etc. In this type it is called nutritional ketosis
One hypothesis that explains the result is : A) Two genes are involved with 12:3:1 epistasis, such that A_B_ and A_bb are black, aaB_ is brown,and aabb is green.
Explanation:
- This is a case of Dominant Epistasis.
- When two genes are involved and presence of dominant allele of one gene masks the effect of either allele of the second gene then the epistasis is termed as dominant epistasis.
- In the given case black :brown: green ratio is approximately equal to 12:3:1.
- Here presence of a dominant A allele that is responsible for the black colour masks the effect of either allele of B. Therefore A_B_ and A_bb produces black beetles
- Again , absence of dominant A allows B to express itself and Brown beetles are produced thus aaB_ is brown.
- When both the genes are present as recessive alleles, neither brown nor black colour is expressed and the beetles are green.Thus, aabb are green.
Answer:
he Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.
Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.
The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.
This can get you started, I didn't want to make it too easy on you! :) It has I believe 126 words, I hope you find it useful!
