After a nuclear disruption in Siberia during the winter, scientists found evidence that the DNA in cells of local wildlife newboms had several mutations. Which of
the following is a valid claim that can be made about how the nuclear disruption led to mutations?
A High temperatures during the disruption caused damage to parental gametes (sex cells) resulting in mutations in newborns
mutations in newborns
B. High temperatures during the disruption caused damage to parental somatic cells resulting.
C Exposure to radiation during the disruption caused damage to parental gametes (sex cells) resulting in mutations in newborns.
D. Exposure to radiation during the disruption caused damage to parental somatic cells resulting in mutations in newborns.
Answer:
The correct answer is choice (B) the
production of proteins. Choice (A)
is incorrect because mitochondria
produce energy for the cell. Choice (C)
is incorrect because the cell membrane
controls the removal of substances
from a cell. Choice (D) is incorrect
because lysosomes break down
chemicals.
Explanation:
C. Exposure to radiation during the disruption caused damage to parental gametes (sex cells) resulting in mutations in newborns is a valid claim that can be made about how the nuclear disruption led to mutations.
What is damaged by radiation while mutations in DNA?Radiation can cause mutations in DNA by damaging the genetic material, and these mutations can be passed on to offspring through the parent's gametes.
This is because radiation can cause mutations in DNA by breaking the chemical bonds that hold it together or by causing other types of damage that alter the sequence of nucleotides. Since gametes are the cells that are involved in reproduction and pass on genetic material to offspring, mutations in gametes can be passed down to future generations.
Somatic cells, on the other hand, are the cells that make up the body of an organism but are not involved in reproduction. Mutations in somatic cells can lead to health problems for the individual but are not passed down to offspring.
Therefore, in this scenario, exposure to radiation during the nuclear disruption likely caused mutations in the gametes of the local wildlife, which were then passed down to their offspring resulting in genetic mutations in newborns.

The single stream recycling program that they partner with makes it convenient to
homeowners since they can put all of their recycling in one bin, what is the major drawback
to this type of recycling?
a. It is inconvenient for homeowners
b. It reduces how much stuff can be recycled
C. It is cost effective
d. It has to be sorted and contamination is higher
Answer:
Putting items in the recycling bin that can’t be recycled can contaminate the recycling stream. After these unrecyclable items arrive at recycling centers, they can cause costly damage to the equipment. Additionally, after arriving at recycling centers, they must be sorted out and then sent to landfills, which raises costs for the facility.

We need to recycle our waste because Earth is a closed system with respect to
matter, and new matter does not enter the environment. Agree or disagree
I disagree because although recycling is good, Earth firstly is not a closed system and new matter enters the environment all the time, such as comets.
In terms of matter, the Earth is often referred to as a closed system. In other words, the total amount of matter on Earth neither changes nor becomes more or less; Instead, it can take on different forms due to different processes. So, I am agree with this statement.
Although the Sun provides the world with continuous energy, most of the actual matter on Earth is recycled and used in various cycles. Recycling of waste is important because it enables us to recover useful materials and resources, reducing the need for mining new raw materials from the earth. Recycling helps us to reduce the environmental damage caused by the extraction and disposal of waste as well as the depletion of natural resources. It helps maintain long-term equilibrium inside a closed system of matter on Earth.

what is photosynthesis?
Photosynthesis is the process by which plants generate simple carbohydrates. This process used the energy from the sun.
Photosynthetic reactions:Photosynthesis refers to the metabolic process by which plants and algae use the energy from the sun and carbon dioxide to generate simple carbohydrates and oxygen.Photosynthetic reactions can be divided into light-dependent reactions and light-independent reactions.The light-independent reactions (also called the Calvin cycle) generate simple carbohydrates such as glucose.In conclusion, in photosynthetic reactions, plants turn carbon dioxide (CO2) and water (H2O) into simple carbohydrates by using the energy from the sun.
