Answer: Gravity is the main force responsible for mass movements. Gravity is a force that acts everywhere on the Earth's surface, pulling everything in a direction toward the center of the Earth. On a flat surface, parallel to the Earth's surface, the force of gravity acts downward.
Which kind of of electrical charge is found on a hydrogen atom of a polar water molecule? A. A negative charge, because of a covalent bond with oxygen B. A negative charge, because of an ionic bond with oxygen C. A positive charge, because of an ionic bond with oxygen D. A positive charge, because of a covalent bond with oxygen
Answer:
D. A positive charge, because of a covalent bond with oxygen
Explanation:
A water molecule contain both hydrogen and oxygen atom. Water is a polar molecule because it has positive electric charge in one of it's poles and negative charge on the other. The hydrogen is positively charged and the oxygen is negatively charged which are bonded by covalent bond. Hydrogen is positively charged because it cannot attract electrons strongly like oxygen which is positively charged. There is unequal sharing of electrons in water molecules and this is why oxygen is slightly negative and hydrogen is slightly positive.

What is a catalyst and how do they help with the chemical reactions needed for metabolism?
Answer:
See explanation
Explanation:
A catalyst refers to any substance that increases the rate of a chemical reaction. A catalyst does not affect the equilibrum position rather it enables the system to attain equilibrum faster.
Biochemical catalysts increase the rate of biochemical reactions in the body. They enable the body to carry out certain important functions that are necessary for life.
Why does diuron cause coral to bleach
Simple answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.
More in depth explanation:
Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.
Hope this helped :)

How does mitosis differ from meiosis? A. Mitosis makes gametes, meiosis makes body cells B. Meiosis makes haploid cells, mitosis makes diploid cells C. Mitosis requires cytokinesis, meiosis does not D. Mitosis makes gametes and meiosis makes zygotes
Answer:
B
Explanation:
Mitosis carries out the process of asexual reproduction, produces two identical daughter cells and forms diploid cells. Meiosis carries out the process of sexual reproduction, forms four different daughter cells and makes haploid cells.
Humans do not go through photosynthesis, however it is still important to us. Why is it so important to us? Be specific.

Explanation:
A researcher has used in vitro mutagenesis to mutate a cloned gene and then has reinserted the mutated gene into a cell. To have the mutated sequence disable the function of the gene, what must then occur
Answer:
recombination resulting in replacement of the wild type with the mutated gene
Explanation:
Recombination is a process of the formation of new alleles when the original ones are broken down into bits and then ‘recombined’.
When mutation of a cloned gene occurs and the mutated gene is reinserted into a cell, the mutated sequence gene function will have to be disabled which involves recombination resulting in replacement of the wild type with the mutated gene.

What information does the author use to support the point of view in "The Problem with Plastic" that is not included in "Make a Change: Alternatives to Plastic Straws"
Answer:
The environmental threat posed by the egregious amounts of plastic waste that have accumulated over the years, and that will likely continue to increase unabated.
The enormous amount of plastic waste that has collected over time and that will probably continue to grow unabatedly poses a hazard to the ecosystem.
What is point of view?A logical argument supported by substantial evidence is a scientific worldview. We need consider what science actually is in order to comprehend why.
Science is a subject that seeks to comprehend the natural world through methodical observation and experimentation.
Because it is a standardized process, the scientific method is significant. Because the steps in the scientific method are methodical, scientists carry out experiments in a predictable way. Thus, such tests may be conducted more widely.
"The Problem with Plastic" suggests that the massive amount of plastic garbage that has accumulated over time and that will likely continue to grow unabatedly poses a threat to the ecology. It is not mentioned in "Make a Change: Alternatives to Plastic Straws."
Thus, this is the meaning of the given quotation.

Why do people feel fireworks before hearing it?
Answer:
People feel fireworks before hearing it because light travels faster than sound.
Explanation:
We always see the colors of the fireworks before hearing their defeaning sounds. This is because light travels faster than sound, so we can see the light before hearing the sound. An example of this is seeing lightning before hearing thunder. When lightning strikes, the air around it moves very quickly, causing vibrations.

Pick one part of interphase in the diagram above and describe its function in the cell cycle. Explain why interphase is important before mitosis begins.
PLZ I WILL GIVE YOU BRAINLIEST
Answer:Girl we’re taking the same test But here’s what i put
The G1Phase
is an intermediate phase occupying the time between the end of cell division in mitosis and the beginning of DNA replication during S phase. Interphase is important before mitosis begins because DNA is duplicated during interphase before the cell undergoes mitosis, the amount of DNA in the original parent cell and the daughter cells are exactly the same.
