g Humans have two sources of cholesterol: absorption from ingested food and de novo synthesis by the liver. High levels of cholesterol in the blood correlates with cardiovascular disease, but cholesterol is required to regulate membrane fluidity and is a precursor for important molecules like steroids and bile acids. Thus, humans evolved several types of regulation of cholesterol levels. How does the human body compensate for excess consumption of cholesterol in the diet
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.
Algal bloom is caused what 2 factors in the dead zone?
0 points
A) Fertilizer
B) Nitrogen
C) Nutrient
D) Rapid growth
E) Phosphorus
F) Animal waste
pls help i need this because of a quiz
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.

what is hormone injection and subcutaneous implants??
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.
which of these is closest to the number of molecules of ATP we get from Anaerobic metabolism of one molecule of glucose? -2
-6
-10
-32
-48
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:
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.
Describe the organization of a synovial joint.
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.

In dust bunnies, short ears are dominant to long ears. If a heterozygous female mates
with a long ear male, what are the chances their offspring will have short ears?
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.
Nerve cells do not replicate their DNA after reaching maturity. A cell biologist observed that there was x amount of DNA in a human nerve cell. In four other types of human cells, labeled A-D, she measured the following amounts of DNA:
cell A, 2x; cell B, 1.6x; cell C, 0.5x; cell D, x
Match the four cell types with the following choices: (1) sperm cell; (2) bone cell just beginning interphase; (3) skin cell in the S phase; (4) intestinal cell beginning mitosis. (Hint: review the phases of the cell cycle and mitosis in chapter 12 if needed!).
Cell Types, Amount of DNA - Specific Cell
cell A, 2x:
cell B, 1.5x:
cell C, 0.5x:
cell D, x:
Answer:
Cell A= Intestinal cell begining mitosis
Cell B= Skin cell in S phases
Cell C= sperm cell
Cell D= bone cell just beginning interphase

Explain the three principles of the cell theory
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.

When DNA replication occurs before meiosis, the original DNA strand
GTC ACA GGC ATC is copied into complementary strand CAG CCG TAG.
What type of mutation has occurred?
A) deletion
B) insertion
o
inversion
D) translocation
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.
#BrainlyIsFunWhich of the following is not a function of tRNA
Answer:
connecting amino acid together to form proteins
hope it will help
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:
Picking up amino acid specified by the codonTranscribing nitrogen bases into mRNA in the nucleus Recognizing appropriate codon in the mRNAAccording to the explanation above, we can see that "connecting amino acids together to form a protein" is not a function of tRNA
