Which will most likely cause an increase in the frequency of genetic mutations in
humans?
А
increased exposure to mold spores in the air
B
increased exposure to the rising levels of atmospheric CO2
с
increased exposure to bacteria in drinking water
D
increased exposure to X-rays
Answer:
Increased exposure to X-rays
Explanation:
X-rays shoot harmful radiation through your body, that's why when you go to the dentist or other places and they take a X-ray they give you a lead vest to protect your organs from unneeded radiation.
hope this helps :)
Increased exposure to X-rays is the most likely cause of an increase in the frequency of genetic mutations in humans (Option D).
A mutation is any alteration in the nucleotide (DNA) sequence of the genome in the cells of an organism.Mutation can be caused by physical factors (e.g., X-rays) or chemical agents (e.g., pesticides such as DDT).X-rays are well known to cause mutations by breaking covalent bonds in DNA, which may be erroneously repaired, thereby leading to deletions of nucleotides.In conclusion, increased exposure to X-rays is the most likely cause of an increase in the frequency of genetic mutations in humans (Option D).

Which solution has cells that are hypertonic?
Answer:
hypotonic solution
Explanation:
Answer:
Compared to fresh water, salt water is a hypertonic solution. This means that for cells to function, they must contain a cytosol that is a more hypertonic solution than salt water. Sea turtles, for example, live in a much more hypertonic solution compared to freshwater turtles.

battery with forces of 20 N and 25 N in the same
direction. What is the resultant force applied on the
car?
Answer:
45 N
Explanation:
Add the forces together if they are going in the same directions.
20 N+25 N=45 N
Energy that is carried by electric current is what energy
Answer: electrical energy
The faster the charges move, the more electrical energy they carry. As the charges that cause the energy are moving, electrical energy is a form of kinetic energy. Lightning, batteries and even electric eels are examples of electrical energy in action!Electrical energy can be either potential or kinetic energy since it's created from an electric charge flow. Continuing with the example of a battery, we know it has electrical potential energy while charging.

(_______) stars, however, will last for several billion years, because
they burn their fuel much more slowly. *
Answer:
Smaller
Explanation:
Life Cycle of a Star
Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size. Very large, massive stars burn their fuel much faster than smaller stars and may only last a few hundred thousand years. Smaller stars, however, will last for several billion years, because they burn their fuel much more slowly.

Como ha llevado la evolucion a que este insecto phyllium giganteumparezca una hoja segun la teoria de lamarck
Answer:
Due to adaptation of the environment.
Explanation:
Evolution has led this insect phyllium giganteum to appear like a leaf according to Lamarck's theory because this insect lives and feed on the leaf environment so in order to save itself from other predators it takes the shape and structure of leave in order to hide itself so this adaptation slowly transmitted from the parents to the offspring and as a result evolution occurs.

How does mRNA help in the differentiation of structures as an organism develops?
A. mRNA creates the amino acid chain that will eventually code for the specific protein that makes up a specific organ.
B.mRNA packages the proteins and takes them out of the cell
C.mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
D.mRNA is stored in the nucleus and carries the genetic code to make all of the specific structures of the body
Answer:
answer is part (C)
Explanation:
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ
mRNA takes the DNA code to the ribosome so that the specific protein can be made that makes up a specific organ. Thus the correct option is C.
What is mRNA?
Messenger RNA is referred to as a type of single-stranded RNA which involved in protein synthesis. mRNA is made from a DNA template during the process of transcription (formation of protein from DNA to RNA).
The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery ribosome reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.
