Explanation:
when the moon stops rotating around the earth
earth will be crush down because it is the pull of the moon gravit on the earth that hold our planet earth in the place.
A greater detrimental effect would have been caused if the moon stops rotating or the Earth stops rotating. This is because the rotating celestial bodies exert some kind of gravitational pressure in order to make them in the exact locations.
What happens when the earth stops rotating?If the earth stops rotating, this inhibition of motion suddenly causes the momentum that would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes.
If the moon stops rotating or the earth stops rotating then the other celestial body disrupts down. Due to this, the pull of the moon's gravity on the earth or the pull of the earth's gravity on the sun holds each other in their exact location.

Which of the following is a critical factor driving evolution?
Environmental conditions
Health in comparison to similar organisms
Ability to acquire food
Strength in comparison to similar organisms
All of these are equally important
all of these are equally important, what if there is an option for natural selection, natural selection would be the most important but for this it's all these are equally important.
The critical factor driving evolution is strength in comparison to similar organisms.
According to Charles Darwin, Organisms that are better able to survive in their environment live long enough to reproduce and pass on these favorable traits to their offspring leading to the perpetuation of these organisms and gradual demise of other individuals of the same species who lack these favorable traits.
This is the origin of the cliché, "survival of the fittest". Hence organisms that lack certain strengths possessed by other organisms are gradually replaced by other individuals having such strengths.

Two students compare and contrast the composition of a plant and animals cells. Several observations are made during the investigation. Which observation is incorrect?
Plant and animal cell contain cell membranes.
Plant cell are contained within cell walls, while animal cells are not.
Plant and animal cells contain a nucleus.
Plant cell do not have cytoplasm.
Answer:
I believe the correct answer would be D- Plant cell do not have cytoplasm
Explanation:
Plant and animal cells both have a cytoplasm so D is the incorrect statement.
Two students compare and contrast the composition of a plant and animals cells. Plant cell do not have cytoplasm this observation is incorrect. Therefore, option D is correct.
What is cytoplasm ?The liquid present inside a cell but not in the nucleus of the cell. In a cell, the cytoplasm is where the majority of chemical processes occur.
The gel-like substance that fills a cell is called cytoplasm. It serves as a catalyst for chemical reactions. It offers a foundation for other organelles to function within the cell. A cell's cytoplasm is where all the processes for cell division, growth, and replication take place.
Rudolf von Kölliker coined the phrase in 1863, first using it as a synonym for protoplasm, but over time it has come to refer to the cell's interior and extracellular organelles.
The first phase of cellular respiration, known as glycolysis, as well as mitosis and meiosis are just a few of the numerous cellular processes that take place in the cytoplasm.
Thus, option D is correct.

Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase.

D. By active transport
Answer: Glucose is absorbed through the intestine by a transepithelial transport system initiated at the apical membrane by the cotransporter
Explanation:
if im wrong ill give you your points
Osmosis best describes how glucose is absorbed into intestinal cells.
What do you mean by osmosis?
Osmosis is the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules, through a cell's partially permeable membrane.
Osmosis is when water moves from an area of LOW solute concentration (low osmolarity) to an area of HIGH solute concentration (high osmolarity) through a semipermeable membrane. Osmosis is one of the most important ways that plants and animals achieve homeostasis.
The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil. Therefore, the water flows into the roots. The guard cells of the plants are also affected by osmosis.

Consider two kinesin motor proteins at the mitotic spindle midzone: kinesin A is a tetrameric motor that walks toward the plus end of both microtubules to which it is attached via its motor domains; kinesin B, on the other hand, walks toward the minus end of one microtubule while it is attached to another microtubule via its tail domain.How do these motors affect the length of the spindle?
A. They both work to shorten the spindle.
B. Kinesin-5 works to shorten the spindle whereas kinesin-14 works to lengthen it.
C. Kinesin-5 works to lengthen the spindle whereas kinesin-14 works to shorten it.
D. They both work to lengthen the spindle.
Answer:
C. Kinesin-5 (kinesin A) works to lengthen the spindle whereas kinesin-14 (kinesin B) works to shorten it.
Explanation:
Kinesins are microtubule-based motors localized in the mitotic spindle in order to ensure the correct segregation of the chromosomes during cellular division. These proteins are classified regarding their sequences at the core motor domains which determine their motility. Kinesins can move along microtubules in opposite directions, walking toward the plus end (i.e., the end that grows more rapidly) or moving toward the minus end. Recently, it has been shown that opposite forces between kinesin-5 (plus-end-directed) and kinesin-14 (minus-end-directed) microtubule-based motors regulate the length of the spindle during cellular division. Kinesin-14 is a minus-end-directed motor protein that walks along microtubules from plus- to minus-end, while kinesin-5 is a plus-end-directed motor protein that walks along microtubules from minus- to plus-end, and thereby they work to shorten and lengthen the mitotic spindle, respectively.

Complete the following sentences that describe glycolysis and gluconeogenesis in both fed and resting states. After a meal the body is in a fed state, which stimulates the pancreas to secrete the hormone insulin . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the dephosphorylation of the bifunctional enzyme. This event causes a(n) increase in the concentration level of the fructose-2,6-bisphosphate (F-2,6-BP). This new concentration of F-2,6-BP activates the glycolysis pathway. In a fasting state, the pancreas secretes the hormone glucagon . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the phosphorylation of the bifunctional enzyme. This event causes a(n) decrease in the concentration level of F-2,6-BP. This new concentration level of F-2,6-BP. activates the gluconeogenesis pathway, by allowing inhibition of the reciprocal reaction.
Answer:
Fed state - Insulin; dephosphorylation; increase; glycolysis
Fasting state - Glucagon; phosphorylation; decrease; gluconeogenesis
Explanation:
Fructose-2,6-bisphosphate is an allosteric regulator of the enzymes phosphofructokinase-1 and fructose1,6-bisphosphatase-1 which are involved in glycolysis and gluconeogenesis respectively.
After a meal the body is in a fed state, which stimulates the pancreas to secrete the hormone insulin . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the dephosphorylation of the bifunctional enzyme, phosphofructokinase-2/fructose-2,6-bisphosphatase. This event causes a(n) increase in the concentration level of the fructose-2,6-bisphosphate (F-2,6-BP). This new concentration of F-2,6-BP activates the glycolysis pathway.
In a fasting state, the pancreas secretes the hormone glucagon . The plasma membrane receptor on the liver binds to this hormone and activates a signaling pathway that results in the phosphorylation of the bifunctional enzyme phosphofructokinase-2/fructose-2,6-bisphosphatase. This event causes a(n) decrease in the concentration level of F-2,6-BP. This new concentration level of F-2,6-BP. activates the gluconeogenesis pathway, by allowing inhibition of the reciprocal reaction.
