Answer:
object x and object y are rubbed together. object x acquires a negative charge, what does object y experience?
a. a gain of protons
b. a loss of protons
c a gain of electrons
d. a loss of electrons
Explanation:
:) answer mom
The charge of object y will be positive since it will have excess proton and less electron.
What is positive charge?A positive charge is obtained when an atom losses its electron usually a metal. It simply defines the excess of proton in an atom or deficient of electron in an atom.
If object x acquires a negative charge, then object y must have supplied the excess electron to it.
Thus, the charge of object y will be positive since it will have excess proton and less electron.

How do we inherit traits from our parents
Answer: Through genes
Explanation:
When a baby is made the parents both pass on traits (genes) to the baby through DNA. The traits that the baby takes are determined by dominant and recessive traits.
Example: If both parents have brown eyes which is a dominant trait the baby will have brown eyes.
Which one of the solutions do you think countries most affected by natural hazards should try? Why?
Please help I will give brainliest!!
Answer:
100 % used of renewable energy.
Explanation:
100 % used of renewable energy by those countries that are affected by natural disasters because renewable energy does not produce any pollution that affect climate. If there is no change occur in the climate, the environment becomes stable and moves towards positive growth of the environment. If there is 0 % pollution is produced in the environment, the environment growth will be increases and equilibrium of environment should be accomplished.

Explanation:
which structure in the figure would most likely be used to form muscles and connective tissue
Q3 because the muscle tissue isnt that complex and it inst that connective.Explanation:
Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.
What is connective tissue?Animals have a specific tissue called muscle that contracts when activated, applying forces to various body parts. Together, these fibers and sheets are referred to as muscles, which regulate many other contractile processes as well as an organism's movements.
Depending on their purpose, animals have one of three types of muscle. Despite modest differences, these muscles have a similar structure and function. Muscle tissue has a unified function and is frequently joined by the same nerve bundles.
Therefore, Bone and muscles are the connective tissue. Muscle tissue is made up of sheets and fibers of muscle cells woven together.

which statement is true about natural selection?
Answer:
I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time. Basically, natural selection says that individuals within a population of a species that have favorable adaptations for their environment will live long enough to reproduce and pass down those desirable traits to their offspring.

Why do classification systems change over time?
O Scientists find new evidence in their studies.
O Scientists use old methods of classification.
O Scientists repeat experiments and find no changes.
O Scientists find similar evidence to previous work.
Classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).
What is Classification System?There are many types of classification systems that are used for different purposes. The classification of organisms takes place in the form of a classification system called Linnaean classification.
Linnaean classification involves the use of organisms grouped using a hierarchy called taxa which includes taxonomic levels and taxonomic groups that animals are placed in based on their characteristics and even shared ancestry.
The different levels of biological classification are as follows:
Species » Genus » Family » Order » Class » Phylum » Kingdom » Domain
It changes over time as scientific studies find new evidence.
Thus, classification systems change over time because scientists find new evidence in their studies. So, the correct option is (A).

Explain how nitrate ions help plants to grow.
Answer:
Explanation:
Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.
Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.
What are the roles of nitrate in the growth of plants?Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.
Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.
Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.

Transcribe the following G G C C G T T T C A C C to mRNA
a) CCG GCA AAG TGG
b) CCG GCU AAG TGG
c) CCG GCU AAG UGG
d) CCG GCA AAG UGG
Answer:
The Answer is D, trust. I got all of them wrong and the system showed that this was the correct one.
Explanation:
The transcription of G G C C G T T T C A C C to mRNA is CCG GCA AAG UGG. Hence, option D is correct.
What do you mean by Transcription?Transcription may be defined as a biological process that involves the transformation of a DNA strand into its mRNA sequence. It occurs in the nucleus of the cell.
In mRNA, Adenine is transcribed into Urcail instead of thymine. So, the mRNA sequence will be synthesized according to that.
Therefore, the correct option for this question is D.
