Why don't lunar eclipses occur during full moons
Answer:
Because the moon's orbit around Earth lies in a slightly different plane than Earth's orbit around the sun, perfect alignment for an eclipse doesn't occur at every full moon. A total lunar eclipse develops over time, typically a couple hours for the whole event.

Organisms that live in the rainforest have developed unique adaptations that aid in their survival. Which adaptation would most likely be found in organisms living in the rainforest? a. herbivores feed on low-lying plants b. birds have beaks adapted to break open hard shells c. insects have a widely-varied diet d. plants are able to store water in their leaves Please select the best answer from the choices provided A B C D
Answer:
Your answer is most probably A). B) implies that nuts are the only thing for birds to eat in a rainforest, which doesn't make sense, C) implies that the insects would need a widely-varied diet to survive, but again there's an abundance of things that a hungry bug can eat, so they don't need a wide dietary coverage, D) suggests that there may be droughts in the area for which the plant may need to be prepared, but in the RAINforest droughts are uncommon.
Answer:
B) birds have beaks adapted to break open hard shells

Answer:
C) The waves amplitude
Explanation:
Answer:
The measurement labeled E is the wave's amplitude.
Explanation:
A vertical rise in a wave length is the amplitude of the wave.
The distance between each curve is the wavelength, if it is a long distance than it is slow if it is a short distance than it is fast.
The waves period is the bottom of the wave where no movement is constant.

Letter X represents
Inorganic molecules
O organic molecules
O biological catalysts
O simple sugars
Answer: b
Explanation:
All the smaller molecules are made up of the organic elements
The study of a living being is called biology.
The correct answer is B.
The process of conversion of a large molecule into a smaller molecule with the help of an enzyme is called digestion. The enzyme converts the organic and complex molecules to the simpler molecule which helps in absorption and later on is used up to form ATP.
According to the question, the larger molecule which is an organic molecule is breakdown into smaller molecules.
Hence, the correct answer is B that is an organic molecule.

C.)was extinct and is now explosive
D.)was dormant and is now explosive
Answer:
The answer is A
Explanation:
Quiet and extinct are not words to describe a volcano that hasn't erupted in a long time. those are called dormant. When they start to heat up, steam or erupt, they are active.

The central atom in an amino acid that all the groups connect to is a
O A. Hydrogen
.
O B. Oxygen
• O C. Carbon
.
O D. Nitrogen
Answer:
C. Carbon
Explanation:
The central atom in an amino acid that all the groups connect to is a carbon atom.
Amino acids are monomeric units of proteins. They are bifunctional in that they have an amino group and a carboxyl group. These groups are attached to a carbon atom, α-carbon, in a molecule.
This is common to all amino-acids.

Having a mutation in a strand of DNA has been known to do which of the following?
a:Stop a protein from being made
b:Causing a harmful genetic disorder
c:Causing no noticeable change
d:Causing a change that can benefit an organism
Causing a harmful genetic disorder is a mutation in DNA.
What is mutation?A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations. Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Our cells are constantly undergoing mutations, yet very few of these have any negative effects on our health. Compared to what we typically see in science fiction movies, this is completely different. A mutation is never so advantageous.
There are numerous explanations for why mutations typically don't have significant effects. One explanation is that our cells have highly advanced machinery for quickly correcting mutations.
Therefore, Causing a harmful genetic disorder is a mutation in DNA.

Answer: But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others. All of these disorders are caused by the mutation of a single gene.
