autonomic reflexes enable the ans to control what kinds of visceral functions? check all that apply.

Answers

Given what we know about the Autonomic Nervous System we can confirm that autonomic reflexes enable the ANS to control functions such as heart rate, urination, and breathing rates.

These are among the many visceral functions that the Autonomic Nervous System controls. As per the pattern that is being established, we can conclude that the Autonomic Nervous System functions at a subconscious level, controlling the visceral functions that do not require conscious thought.

Despite this, some organs can also be controlled consciously, such as the lungs and bladder. Other visceral functions such as heart rate, digestion, and even ocular responses, are not able to be controlled consciously.

Describe prokaryotic cells. Include general characteristics and indicate the one feature that eukaryotic cells have that prokaryotic cells do not.















Please no links!

Answers

Answer:

prokaryotic cells — e.g. Bacteria

eukaryotic cells — e.g. Animal/Plant cells

Prokaryotic Cells are unicellular organisms that don’t have a nucleus, but have their DNA unbound (or uncompressed) within the cells cytoplasm, they also have circular structures (or rings) called plasmids which carry additional Genetic Information.

Specific Example:  A bacterium is an example of a prokaryotic cell, and it has a cell wall, cell membrane, and even a capsule.

One feature that Eukaryotic cells have which Prokaryotic cells don’t is a Vacuole (this is just one feature).

Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and don’t have organelles. Many also have a capsule or slime layer made of polysaccharide (ignore this word if you havent learn about it yet).

What is biochemical reaction?

Biochemical reactions are chemical processes that occur in live cells to support life and promote cell growth.

To expedite most biochemical reactions, an enzyme is a type of biological catalyst.

The amount of activation energy required for the reaction to start is decreased by enzymes. Most enzymes are proteins that only interact with one particular chemical, known as their substrate.

The ratio of atoms in the reactants and products must always be balanced.

They have the capacity to store energy as a covalent bond. They have the ability to alter the cell's energy's shape. They follow the laws of physics and chemistry.

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is
needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a social consequence of not using the land
for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community
Preserving the ecosystem may upset residents in a community with a hospital shortage.
O If the wetland is protected, residents have fewer environmental concerns about the area.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.

Answers

The social consequence of not using the land is that it will protect the lives of species and prevents a reduction in carbon sequestering by the trees.

A social consequence refers to any unforeseen event which can be positive or negative, experienced by a society and has an effect on them.

A positive social consequence benefits a group of the socially connected group and can also stimulate future purpose.

A negative social consequence has its repercussions and can be attributed to negligence and bad factors.

Conservation of the ecosystem is paramount as well as the survival of the community.

A positive social consequence from the given information is that if the forested wetland is preserved to support a variety of species, It will protect the lives of the species and prevent a reduction in carbon sequestering by the trees.

The community could have emergency ambulances to cater for the movement of patients in case of emergency to the hospitals or educate them on how to take good care of their health and how to minimize hazards at home and offices.

when the lac repressor protein binds to lactose, why does it fall off its binding site at the operator?

Answers

Answer:

English is not my native language so sry if there's any grammaticaly mistake

Explanation:

cuz it changes its shape and forme u got that?!

Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.

What do you mean by Lac repressor?

Lac repressor prevents the transcription of genes involved in lactose utilization in E. coli, such as lac genes.

When lactose becomes available a small amount of it is taken up by lactose permease and converted to allolactose by the enzyme beta-galactosidase.

Therefore, Lactose falls off its binding site at the operator because the allolactose binds to the repressor causing it to fall off the operator side.
