Answer:
thymine
Adenine always bonds with thymine, and cytosine always bonds with guanine. The bonding causes the two strands to spiral around each other in a shape called a double helix. Ribonucleic acid (RNA) is a second nucleic acid found in cells. RNA is a single-stranded polymer of nucleotides.

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.

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.

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.

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.

Answer:
C. W is a metal and X is a non-metal
Explanation:
The elements in the "Periodic Table" are arranged in groups according to their characteristics.
X- Selenium
Z- Xenon
W- Magnesium
Y- Barium
A. X has a lower boiling point than Y. Selenium's boiling point is 685 while Barium's boiling point is 1,140. This makes choice A incorrect.
B. Y is a metal while Z is a non-metal. This makes choice B incorrect.
C. Both W and X are non-metals. Both are in the Alkaline Earth group. This makes choice C correct.
D. Z has different chemical properties than W because they don't belong in the same group. Z is a noble gas while W is an Alkaline Earth Metal.

fishing went as far as destabilizing the ecosystem
E)
all of the above
Answer:
D
Explanation:
Just took the quiz
The Newfoundland moratorium on cod fishing was unsuccessful because fishing went as far as destabilizing the ecosystem (Option D).
What was the Newfoundland moratorium?The Newfoundland moratorium was a legal issue where the Canadian fed government banned cod-fishing along its east coastline.
This moratorium was critical for maintaining biodiversity levels in the geographic area.In conclusion, the Newfoundland moratorium on cod fishing was unsuccessful because fishing went as far as destabilizing the ecosystem (Option D).

which of the following molecules is likely a carbohydrate?
a) H2O
b) C11H22O11
c) C2H17O2
A carbohydrate is a molecule that contains hydrogen and oxygen in a ratio of 2:1 like water.
The term carbohydrate simply means "a hydrate of carbon". This molecule can be broken up into carbon an water.
For this to be possible, the molecule must contain hydrogen and oxygen in a ratio of 2:1 as in water.
This is only possible in C11H22O11. The hydrogen to oxygen ratio is 2:1 hence the compound is a carbohydrate.

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.

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.

How do biologists model changes in a population?
Answer:
When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth. When the per capita rate of increase ( r) decreases as the population increases towards a maximum limit, then we get logistic growth.
