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.

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.

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:

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.

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.

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.
