edge 2020
Deletion mutation is an example of frame-shift mutation.
FRAME-SHIFT MUTATION:Frame-shift mutation is a type of mutation in which the reading frame of a DNA (nucleotide) sequence is altered.
DNA or RNA is made up of nucleotides subunits, which is read in a particular pattern. When this reading pattern is shifted, frame-shift mutation is said to occur.
Deletion mutation and insertion mutation are the two kinds of mutation that results into frame-shift mutation.

Why have American's portion sizes become larger in the last decade?
Answer:
American's portion sizes have become larger in the last decade due to the expanding of food industries and marketing campaigns that tell us to eat more.
Explanation:
The growth of food industries in the last decades to obtain more money in combination with the media influence has led us to eat more, thus why the size of our portions has increased their size.
Another theory states that people always want to eat more, and the industry has only fulfilled this demand, but it is not clear why, in the past, this did not happen.

Which statement is scientifically based? Mutations rarely occur. All mutations are harmful. Some mutations can be contagious, like infections. Mutations are not passed from parent to offspring.
Answer:
Mutations rarely occur
Explanation:
Mutations are genetic changes, i.e., alterations in the DNA sequence. Generally, mutations have deleterious effects, but there are exceptions where mutations may confer an adaptive advantage in a given environment. Mutations are often deleterious, and thereby these genetic changes are rare events. In consequence, mutation rates, i.e., the frequency by which new mutations arise in an organism over time, are generally very low. Finally, mutations that arise only in germ cells can be inherited from a generation to the next generation, while somatic mutations cannot be inherited.
The statement which is scientifically based is: A. Mutations rarely occur.
Mutation can be defined as a change (alteration) in the nucleotide sequence or genetic sequence of a living organism, which result in a variant form that may be transmitted to successive generations.
Basically, mutation is typically caused by a change (alteration) of single base units in deoxyribonucleic acid (DNA) or the insertion, deletion and rearrangement of an organism's genes or chromosomes.
However, mutations rarely occur in most living organisms due to the regulation and control of cell growth through cell cycle.
In conclusion, mutations rarely occur in most living organisms based on scientific researches.

The plum pudding model of the atom states that
each atom has an overall negative charge.
each atom has a dense, positively charged center.
an atom is a solid, indivisible sphere that makes up all matter.
an atom is made up of electrons in a sea of positive charges.
Answer:
D
Explanation:
Took the test lol
Carbon (C)
Atomic #: 6
Atomic Mass: 12
Question: Calculate the number of electrons using the information given. Write the number on the line and then draw the electrons into the Bohr model.
Assuming the atom has a neutral charge, the number of electrons will be the same as the number of protons. The number of protons is given by the atomic number, 6, so there are six electrons.
The first "ring" of the atom (closest to the center) can take two electrons, so draw two electrons there. The second (outer) "ring" of the atom can take the remaining electrons, so draw four electrons there.
Atomic mass is irrelevant in this specific problem.

RNA is a molecule with characteristics and a role similar to DNA. Why is RNA necessary for DNA to fulfill its function?
Answer:
eeee
Explanation:
The study of the cell is called cell biology.
The correct answer is C.
In an organism, the expression of the character is due to the formation of the protein molecule in the body which shows its effect.
Protein is formed by the amino acid and the information stored to code the amino acid is in RNA.
Hence, DNA is converted into RNA for the formation of protein and it is also a checkpoint to avoid the mutation.
Hence, the correct answer is C.

male and female reproductive systems?
a. Nourishing and protecting a developing
embryo.
b. Producing gametes (sperm and egg cells) that
unite inside the female reproductive system.
c. Removing nitrogenous wastes and excess water
from the blood.
d. Producing gametes (sperm and egg cells) that
unite inside the male reproductive system.
Answer:
b. Producing gametes (sperm and egg cells) that unite inside the female reproductive system.
Explanation:
The "gametes" refer to the sex cells in humans. The female sex cells are called "egg cells" and these are being produced by the ovary. The male sex cells are called "sperm cells" and these are being produced by the testicles. After copulation, there's a probability for the egg cells and sperm cells to unite. They unite inside the female's reproductive system, specifically inside the "fallopian tube."
Which bird is best adapted to survive in an environment dominated by seed-bearing plants?
Answer:
hummingbirds
Explanation:
Over many generations, hummingbirds have evolved beaks that are long, thin and well adapted to reach into flowering plants and extract nectar
hummingbirds evolved with long thin beaks and well adapted to reach, extract nectar from flowering plants.
What is bird adaptation ?
An adaptation is any inherited mechanism that makes an organism better able to survive in the changing environment.
It can be structural, behavioral features which help organism to survive.
Example is a hawk's feet and sharp claws are types of adaptations help it to hunt and capture mice.
Another adaptation is habitat where organisms having a specific habitat adapt different features.
Bird beak adaptations is the best example where they use their beaks for acquiring meals, consuming, help in climbing, and protection.
Bird beaks adapted enough to assist them to discover specific meals inside their habitat.
Birds have adapted feathers which make them flight simpler like Long feathers and tail of birds provide them steadiness and insulation.

Answer:
An arctic fox changes its fur color to blend in with its surroundings
Explanation:
This is a defense mechanism because when it blends into its surroundings it can hide from its predators and help defend itself
The example most accurately describes a defense mechanism used by an animal is a baby goose recognizes its mother and follows her movements. Thus, option B is correct.
What is arctic fox?An arctic fox changes its fur color to blend in with its surroundings and this is a defense mechanism because when it blends into its surroundings it can hide from its predators and help defend itself.The brown color camouflages the brown fox in the forest.
Adaptation is changing of character of an organism for a short time to survive in severe environmental conditions.The brown color camouflages the arctic fox when the snow melts during the summer. The white color camouflages the arctic fox during the winter.
There are various factors which control the regulation of a gene. Temperature can be a regulatory factor for certain genes. Probably, during the warm temperatures, the proteins regulating the fur colour to become reddish brown become activate these genes. As a result, the fur becomes evident.
Therefore, The example most accurately describes a defense mechanism used by an animal is a baby goose recognizes its mother and follows her movements. Thus, option B is correct.
