A model of pluripotent vs differentiated cellular gene expression is shown. Pluipotency is found in stem cells that have the ability to become multiple types of cells. Differentiation is the process where a cell becomes specialized and cannot return to its pluripotent state. What explanation best supports the model of pluripotency and differentiation shown above?A) Differentiated cells have different DNA sequences that pluripotent cells and can produce different protein products. EliminateB) Differentiated cells have fewer gene sequences that pluripotent cells and can only produce limited numbers of proteins. C) Pluripotent cells recruit molecules from nearby cells to increase gene expression while differentiated cells use only internal transcription factors. D) Differentiated cells and pluripotent cells have different types of activator or repressor proteins present that positively and negatively regulate gene expression in the cell.

Explain what type of stimulus each sense organ responds to and how.

Answers

The sense organs contain receptors that are sensitive to stimuli.

The nervous system consists of the central nervous system - brain and spinal cord -and peripheral nerves. Nerve impulses travel through the axons of neurones - nerve cells. Reflex actions are fast, automatic and protective responses.

Human vision is binocular, which gives us a good perception of depth. Vision defects include short-sightedness, long-sightedness and colour blindness.

when a grasshopper eats grass only some of the energy from the grass is stored in the Grasshoppers body how does the grasshopper use the rest of the energy

Answers

Answer:

The rest of the energy from grasshopper will be transferred to the next trophic level in the food chain with in the ecosystem.

Explanation:

All the organisms with in an ecosystem are part of some food chain. Hence when ever an organism feed upon some other organism/plant to get energy , retains some part of it and  transfers the rest of energy to the next trophic level.

Usually in a food  chain, all organisms retain 10% of the energy they get from the preceding trophic level and transfers 90% of the energy to the next trophic level.

Thus, whichever organism feed on grasshopper or depend for food on grasshopper in some or the other way will get the rest of the energy.
Energy must constantly flow through an ecosystem for the system to remain stable. it means that organisms must eat other organisms

What are foreshocks and aftershocks? *

Answers

Answer:

Explanation:

Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 fault lengths distance from the mainshock fault.

Foreshocks are relatively smaller earthquakes that precede the largest earthquake in a series, which is termed the mainshock.

Answer:

Fore shocks is getting shocked before you have seen what happened while Aftershocks is getting shocked after you have seen what happened.

Everglades National Park has a very large population of white-tailed deer. Which of these changes within this habitat is MOST LIKELY to harm only weaker, older deer, but not younger and healthier deer?A) a drought which decreases the food supply
B) a slight increase in the Florida panther population
C) a fire that burns thousands of acres of the Everglades
D) a large increase in the number of cars driving through the Everglades

Answers

Answer: B) a slight increase in the Florida panther population

A slight increase in the Florida panther population is most likely to harm only weaker, older deer but not younger and healthier deer because panther population being predator is the limiting factor for large population of white-tailed deer. A limiting factor is a resource or environmental condition which limits the growth and distribution of a population in any habitat. Here, the weaker and older deer will be the center of attraction of panther population (predator) as this deer cannot rescue itself from panther population as compared to younger and healthier deer. Weaker and older deer have no survival advantage over increased panther population.
I think the answer is B because  a drought would affect everyone so would a fire because there wouldnt be a home for the younger healthier deer.
Hope this helped in some way :)

20. Which of the following is an example of homeostasis?A human participates in vigorous activity on a hot day and eventually suffers from dehydration.
A human body loses too much heat on a cold day, and hypothermia occurs.
A cactus stores water during wet periods, allowing it to live through dry periods.
A snake rests in the sun on a summer day, and its body temperature eventually becomes too hot for survival.

Answers

Well,

Homeostasis means "maintaining the status quo."  That just means remaining the same.

The first, second, and fourth options, do not represent homeostasis, as something happens to the organism that is not normal.

The third example is an example of homeostasis because the cactus is preparing for the dry period, during which it can maintain the status quo because of its stored water.
A cactus stores water during wet periods, allowing it to live through dry periods.
