Answer:

The bones of a synovial joint are surrounded by a synovial capsule, which secretes synovial fluid to lubricate and nourish the joint while acting as a shock absorber. The ends of the joint bones are covered with smooth, glass-like hyaline cartilage which reduces friction during movement.

Answer:

Explanation:

Cholesterol is an important dietry intake that is gotten from saturated fats

About 200–300 mg of this dietry intake is produced or added daily.

The body compensates for excess cholesterol intake by reducing the amount of cholesterol that is synthesized. This is done by reusing the existing cholesterol in the body and the excretion of excess cholesterol into the digestive tract this is done by the liver through the bile.

About 50% of the excreted cholesterol is reabsorbed back into the bloodstream for use by the small intestines.

Explanation:

Fat molecules consist of three fatty acid chains connected by a glycerol backbone. Fatty acids are basically long chains of carbon and hydrogen and are the major source of energy during normal activities.

Fatty acids are broken down by progressively cleaving two carbon bits and converting these to acetyl coenzyme A. The acetyl CoA is the oxidized by the same citric acid cycle involved in the metabolism of glucose. For every two carbons in a fatty acid, oxidation yields 5 ATPs generating the acetyl CoA and 12 more ATPs oxidizing the coenzyme. This makes fat a terrific molecule in which to store energy, as the body well knows (much to our dismay).

The only biological drawback to this, and other, forms of oxidative metabolism is its dependence on oxygen. Thus, if energy is required more rapidly than oxygen can be delivered, muscles switch to the less efficient anaerobic pathways. Interestingly, this implies that an anaerobic workout will not "burn" any fat, but will preferentially deplete the body of glucose. Of course, your body can't survive very long on just anaerobic metabolism...it just can't generate enough energy.

Answer:

It's true!!!!!❤️❤️❤️❤️

Answer:

You answer is B

Explanation:

This is the only possible answer because when animals die they might get trapped under layers of bone conserving the bone, and B is the answer because if bones are conserved in the sediment Scientists may be able to recognize certain animals for example, 1000 years ago a cow dies and is buried by sediment, the skeleton remains allowing scientists in the present year to analyze it, they might notice slight changes in things like the bones, or the teeth, etcetera, thus this is how Scientists found proof of evolution.

the only flying mammal is a Bat

In this particular insertion there is an insert of three bases. Complementary strands in DNA are the opposite strand, so Adenine is coupled to Thymine and Guanine is coupled to Cytosine.

tbm queria saber essa pergunta!!

Answer:

Dead zones are generally caused by significant nutrient pollution, and are primarily a problem for bays, lakes and coastal waters since they receive excess nutrients from upstream sources. Excess nitrogen and phosphorus cause an overgrowth of algae in a short period of time, also called algae blooms.

Answer:

50% or 1/2

Explanation:

This question involves a single gene coding for ear length in dust bunnies. The allele for short ears (S) are dominant to the allele for long ears (s). This means an heterozygous individual (Ss) will possess short ears.

According to this question, If a heterozygous female (Ss) mates with a long ear male (ss), the parents will produce gametes as follows:

Ss - S and s

ss - s and s

Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:

Ss, Ss, ss, ss

- Ss (1/2 or 50%) offsprings will have short ears.

- ss (1/2 or 50%) offsprings will have long ears.

Answer:

Dehydration synthesis

Explanation:

Combination of monomers to form a covalent bond usually with the release of water molecules

Answer:

KrF2 + H2O -> Kr + O2 +2HF

Explanation:

You would just need to add a 2 on the HF, because on both sides it can balance with 2F's and 2 H's

Answer:d.Additional evidence will change the theory of evolution into a law.

Explanation:

Answer:

amino acids, proteins, living cells, tissue, organs, living things

Explanation:

Amino acids make up proteins. Proteins can be found in cells. A group of cells is a tissue. A group of tissues is an organ. A group of organs make an organ system. And a group of organs systems make a living thing.

Answer:

A or C

Explanation:

B and D are plain illogical. C is definately true, but since it's a little too broad I'm thinking that it would be A, since natural disasters can decrease populations which can destroy genetic diversity (see founders effect).

Answer:

The correct answer is C. I just took the test on plato

Answer:

the answer is false

Explanation:

Answer:

It's false, because rough endoplasmic reticulum is the site of protein synthesis, not smooth endoplasmic reticulum, the smooth ER is the site of lipids, not protein synthesis :3

Explanation:

The contraceptive injection is a shot that contains hormones, either a progestin alone, or a progestin and an estrogen together, that stop your body from releasing eggs and thickens the mucus at the cervix. You need one shot either once every month or once every three months from a healthcare provider. However once injected, it is not reversible, i.e. in case of side effects it cannot be stopped. The way it works is similar to the pill, or the ring, except you don’t have to remember to take it every day or week, but it probably isn’t the best choice for those scared of needles.

Answer:

D) It contains compounds and is therefore a substance

Explanation:

A mixture is composed of multiple compounds.

Answer:

C it is.

Answer:

The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

Explanation:

Can I have brainliest?

Answer:

Answer: 1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.

Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

connecting amino acid together to form proteins

Option D is correct. "connecting amino acid together to form a protein" is not a function of tRNA

Unlike DNA, there are three types of RNA that are involved in protein synthesis, messenger RNA, ribosomal RNA, and transfer RNA.

Ribosomal RNA (rRNA) and transfer RNA (tRNA) are not copies of the info in DNA, instead, their codes are created while in the DNA and then cut into smaller coded fragments.

Transfer RNA (tRNA) is found in cells' cytoplasm and ensures the correct amino acids are carried to mRNA codons to form polypeptide chains during protein synthesis. tRNA takes the amino acid to the correct location for protein synthesis in the ribosome.

Some of the functions of tRNA include:

According to the explanation above, we can see that "connecting amino acids together to form a protein" is not a function of tRNA
