how does a liver cell respond to insulin
Answer:
Insulin stimulates the liver to store glucose in the form of glycogen. A large fraction of glucose absorbed from the small intestine is immediately taken up by hepatocytes, which convert it into the storage polymer glycogen. Insulin has several effects in liver which stimulate glycogen synthesis.

Which behavior shows a way that animals defend their territory
Answer: Territorial behaviour, in zoology, the methods by which an animal, or group of animals, protects its territory from incursions by others of its species. Territorial boundaries may be marked by sounds such as bird song, or scents such as pheromones secreted by the skin glands of many mammals.
Explanation:
Answer:
Wolves work together to chase or kill any wolves that are not in
their group
Explanation:
Many animals rely on smells to mark their territories, spraying urine, leaving droppings or, rubbing scent glands around the territories' borders. Approaching animals will be warned off the territory without ever encountering the territory's defender.

Explanation:
if a light bulb is off; how can you tell that It has been used recently? ANSWER ASAP
If you have a second fixture around, you can use the same test of putting a tube in a working socket and see if it lights. It is not uncommon in fluorescent fixtures to have the ballast burn out. You may detect a burnt smell or see the bulbs flickering.
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.
Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

In this sequence of events (ecological succession), the lichens functioned as a class of pioneer organisms (Option C).
What is ecological succession?Ecological succession refers to the progressive emergence of different organisms and/or species in an ecosystem.
The ecological succession occurs after a period of ecological disturbance in the ecosystem.The ecological succession is fundamental for recovering the homeostasis of the ecosystem.In conclusion, in this sequence of events (ecological succession), the lichens functioned as a class of pioneer organisms.

how does fertilizer affect the quality of crops?
Answer:
Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That's why mineral fertilizers are used to supplement the soil's nutrient stocks with minerals that can be quickly absorbed and used by crops

[tex] \huge \mathsf \pink{Answer}[/tex]
The role of fertilizers in food production is usually underestimated. Fertilizers are food for plants.
Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That’s why mineral fertilizers are used to supplement the soil’s nutrient stocks with minerals that can be quickly absorbed and used by crops.

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.

As sister chromatids separate, cells enter ____ and they finish separating and a nucleus reforms around each set of new chromosomes in ____ . During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.
Answer:
cell; prophase. prometaphasemetaphase. anaphase, telophase.Explanation:
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. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.
