On these chromosomes, which pair of genes would be most likely to be separated by crossing-over: a and b, or a and c? why?.
Answers
The crossing over to the chromosome would be taking place in the A and C sections. Because the crossing of the chromones leаds to the division of the cells tаke plаce аt the prophаse which is the lining of the chromosomes closes together. This tаkes plаce аt then 2 ends.
What is the crossing over?Chromosomаl crossover, or crossing over, is the exchаnge of genetic mаteriаl during sexuаl reproduction between two homologous chromosomes' non-sister chromаtids thаt results in recombinаnt chromosomes. It is one of the finаl phаses of genetic recombinаtion, which occurs in the pаchytene stаge of prophаse I of meiosis during а process cаlled synаpsis. Synаpsis begins before the synаptonemаl complex develops аnd is not completed until neаr the end of prophаse I. Crossover usuаlly occurs when mаtching regions on mаtching chromosomes breаk аnd then reconnect to the other chromosome.

Explain why it is very important for the gametes to divide by meiosis. What could happen if the gametes accidentally divide by mitosis? can someone answer in a sentence!!
Answers
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation: Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid.

This rise is detected by the liver, which releases the hormone
insulin into the blood. Insulin makes the pancreas remove the
extra glucose from the blood and store it as starch.
Later on, the concentration of glucose in the blood drops. The
liver breaks down fat so that it goes up again.

2. A lunar eclipse can occur when the Moon is in......in its orbit.
Help me this is from amplify
Answers
Answer:
Lunar eclipses can only happen when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon. But lunar eclipses do not occur every month because the Moon's orbit is tilted five degrees from Earth's orbit around the Sun. Without the tilt, lunar eclipses would occur every month.
A lunar eclipse occurs when the moon moves into the earth's shadow, it occurs when the earth, moon, and sun are close together.
What is a lunar eclipse?When the Moon passes through the shadow of the Earth, a lunar eclipse happens and also depends on the sun.
Only on the night of a full moon when the Moon is close to either lunar node can the Sun, Earth, and Moon be precisely or extremely closely aligned with Earth between the other two.
When the Moon and Sun are on opposing sides of Earth, a total lunar eclipse takes place. When only a portion of the Moon is covered by Earth's shadow, a partial lunar eclipse occurs.
Therefore when the moon moves into the earth's shadow lunar eclipse happens.

catalyzed particular chemical reactions – in this case, reactions that broke down the film of eye goo that accumulated on my contacts after a week of use. (Presumably, the reason it stung when I got it in my eyes was that the enzymes would also happily break down eye goo in an intact eye.) In this article, we’ll look in greater depth at what an enzyme is and how it catalyzes a particular chemical reaction.
Enzymes and activation energy
A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too.
Enzymes perform the critical task of lowering a reaction's activation energy—that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.
What is the process called when two glucose molecules bond together to form a
disaccharide and why is it important.
Answers
Answer:
Dehydration reaction (a condensation reaction)disaccharide will provide energy for chemical reactions in the body to take place.
Explanation:
The Condensation Reaction is an organic reaction in which two molecules combine to give a single product accompanied by the formation of a molecule of water H2O. Disaccharides are produced when two monosaccharides are chemically combined. The bond called O-glycosidic, is the bond by which monosaccharides join to form disaccharides or polysaccharides. In this type of bond, an OH group of an anomeric carbon of a monosaccharide reacts with an OH group of another monosaccharide, releasing a water molecule.The main function of disaccharides is to provide energy to the cells of the human body, or glycogen. This is achieved through enzymes that act in the synthesis of the disaccharide, extracting glucose. Among the main and best known enzymes that act in this process are insulin for sucrose, lactase for lactose, and trehalase for trehalose.
how did the frame shift change the amino acid
Answers
During translation, the sequence of codons is read in order from the nucleotide sequence to synthesize a chain of amino acids and form a protein.
Therefore, frameshift mutations result in abnormal protein products with an incorrect amino acid sequence that can be either longer or shorter than the normal protein.
