HELP WILL GIVE BRAINLIEST IF CORRECT: What effect do plants' roots
have on rock?
a. They hold it together
b. They weather it
c. They cause it to undergo chemical changes
d. They break it apart
Answer: C
Explanation: Reason why is because whenever the roots put pressure on the rock it cracks open and all the minerals release so it has to be going thru a chemical change because the roots receive the minerals from the rock or stone ...
Answer:
im guessing d but im not sure..,
Explanation:
When these roots grow, they exert pressure on the rock around them, causing the gaps to widen or even crack. Plant roots can also weather rock through chemical processes. When dead roots decompose, they release carbon dioxide; this is sometimes converted into carbonic acid, which chemically breaks down rock into soil.

Explain how the interaction of the Sun, the atmosphere, and the oceans produce winds.
Answer:
The heating of the Earth's surface and atmosphere by the sun drives convection within the atmosphere and ocean. This convection produces winds and ocean currents. The greater the pressure differences between a low-pressure area and a high-pressure area, the stronger the winds.

Which of the following individuals is true-breeding for all traits? A. RrYY B. RRYy C. RRYY D. RrYy ellus Corporation. All Rights Reserved.
The true breeding individual for all traits is RRYY.
What is True breeding ?A true-breeding organism, sometimes also called a purebred, is an organism that always passes down certain phenotypic traits to its offspring of many generations. This means that the parents are homozygous for every trait.
Since RRYY is homozygous for all traits, it will be a true breeding organism if crossed over with another RRYY organism. This is because all the off-springs produced from this cross will also be RRYY that is purebred.

Which kingdoms contain organisms that have cell walls?
The function of cell wall is to provide protection. The kingdoms which have cell walls are fungi and plantae.
What is the function of cell wall ?The cell wall provides the protection against the mechanical stress and the pressure that a cell membrane can not handle.
Cell wall is majorly present for the purpose of protection to the species and these species tend to be delicate and tend to be in more danger.
Cell wall of fungi is made up of chitin and it is polysaccharide having the amino glycosidic linkages.
Cell wall of plants is made up of polysaccharides as well where the cellulose is present in chains.
Cellulose provides the tensile strength and this amino glycosidic linkages tend to provide strong skeletal structures in order to provide protection to the specimen.
Therefore only plantae and fungi have the cell walls.

Describe how Mendel performed his pea plant experiments.
Answer:
Every offspring does not look alike they change with the generations
Explanation:
With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline, sometimes due to climate change, and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring may have no effect at all, be beneficial, or be harmful. will primarily be harmful. will only speed the decline and extinction of the species. could either be beneficial or harmful.
Answer:
be beneficial.
Explanation:
Mutations of DNA sequences of the frog genome that are inherited by offspring will be beneficial for the frog because this mutation in the genetic makeup of frog provides resistance in this new environmental conditions. This mutation occurs due to the exposure of cell's DNA to the environmental factor which gives benefit to the organisms to survive different condition which can't tolerate by their parents so this mutation is beneficial for that offspring of frog.
