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?.

Answer:

c they do not have a backbone

Explanation:

Invertebrates are animals that neither possess nor develop a vertebral column (commonly known as a backbone or spine), derived from the notochord. This includes all animals apart from the subphylum Vertebrata. Familiar examples of invertebrates include arthropods (insects, arachnids, crustaceans, and myriapods), mollusks (chitons, snail, bivalves, squids, and octopuses), annelid (earthworms and leeches), and cnidarians (hydras, jellyfishes, sea anemones, and corals).

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.

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.

When your immune system attacks and destroys the insulin-producing beta cells of the pancreas.

Diabetes is caused by genes and environmental factors around you, such as viruses, that might trigger the disease.

Answer:  Shortly after a heavy meal, the glucose levels increase. This rise is detected by the liver, which releases the hormoneinsulin into the blood. Then cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal.

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.

Answer:

An allele is a viable DNA (deoxyribonucleic acid) coding that occupies a given locus (position) on a chromosome. Diploid organisms, for example, humans, have paired homologous chromosomes in their somatic cells, and these contain two copies of each gene. ...

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.

Answer:

The cell pictured in the diagram is a plant cell because there is are chloroplasts. Chloroplasts are located in plant cells and not in animal cells. Chloroplasts are where photosynthesis occurs, and photosynthesis does not occur in animals.

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.

Explanation:

The ability of cardiac muscle cells to contract spontaneously without a stimulus form a nerve source is called Automaticity. It is a ability to contract without direct stimulation by nervous system.

Cardiac muscle cells has special characteristic which called automaticity , allows cardiac muscle cell to contract spontaneously without a stimulus form a nerve source. Property of cardiac cells to generating spontaneous action potentials.

Automaticity is to do things without occupying the mind with the low level details required to become an automatic response habit. Learning , repetition and practice is the resultant. It is fundamental physiological function in organisms to initiated by specialized populations of cardiac cells.
