which receptors respond to stimuli within the body?

Answers

Answer:

Sensory receptors respond to stimuli.

Explanation:

They can be classified by their location, the type of stimulus they detect or by their structural complexity.

Sensory receptors  are the receptors which respond to stimuli within the

body. The body have five major sensory organs which include the eyes,

nose, tongue, ear and skin.

These organs have receptors which is responsible in the transmission of

signal to the brain for action. The brain acts depending on the signal

received which is usually in the body's best interest.

This makes our sensory organs important and very delicate and as a result

should be adequately protected and taken are of.

Answers

Answer:

Warm ocean air rises into the storm

Explanation:

Most of us know that heat rises so when the heat from the ocean rises it adds into the storm and creates a low-pressure area under the clouds which then continues to build heat and the winds reach to around 74 MPH to be classified as a hurricane.

State 2 of Newtans three laws
(PLS HELP ASAP!!)​

Answers

1. Something at rest or in motion in all constants will remain that way unless acted upon by a force.

2. F=ma

Explanation:

Newton’s first law states that if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.

Force equals mass times acceleration; it states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.

O C. The tail of a dog
O D. The leg of a horse

Answers

D the leg of horse because I took the test

The homologous structure to the forearm of humans is the leg of the horse.

What are homologous organs?

Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.

The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.

Homologous organs have different functions in organisms.

Plants that we reconize today spend the majority of their life in the “blank”

A) haploid Phase

B) seed phase

C) diploid phase

D) gametophyte

Answers

Answer:

The answer is C diploid Phase

Answer:

The answer is C.

Explanation:

Plants that we reconize today spend the majority of their life in the diploid phase.

During the sporophyte phase, a diploid plant body (one with two sets of chromosomes) develops and finally generates spores via the process of meiosis. Mitotic division of these spores results in the formation of gametophytes, which are gamete-producing organisms that are haploid (have a single pair of chromosomes).

Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on dividing cells

Answers

The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.

Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.

During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.

When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.

evaluate the statements below and determine which is the best reason that bacterial cells use operons and polycistronic rna.

Answers

Given what we know about bacterial cells and their genetic mechanisms we can confirm that they use operons and polycistronic RNA for efficiency.

Bacterial cells are vastly different from human or animal cells. Some of these differences include:

Lack of compact DNALack of organelle surrounded by plasmatic membranesThey have cell wallsMay possess flagella

and many others.

Among these differences is the way in which they encode for the proteins the bacteria will produce. Unlike human cells, bacteria use polycistronic RNA. Where a human strand of mRNA will carry the genetic message to create one protein, the polycistronic mRNA of a bacterial cell will provide the information necessary to create multiple distinct proteins.

Bacteria use this in conjunction with operons, to create very efficient protein manufacturing processes. Operons are sections of DNA in which proteins with similar functions are grouped together in order to make it easier to create the polycistronic mRNA strands.

B. What are two ways Smoky can increase his speed? (Use Newton's 2nd Law to help you)
C. What is an example of an action and reaction at work in this picture? (Use Newton's 3rd Law to help you)

Answers

The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.

At point B, Alberto's distance covered increases with time, equal distance is covered in equal time interval. The speed increases uniformly. At the point C to D, the distance covered with time remains the same. At the point D, equal distance is no longer covered in equal time intervals.

According to the law of inertia, an object will remain at rest or in a state of uniform motion unless it is acted upon by an unbalanced force. This means that smokey mouse will continue moving uniformly unless a force acts on it.

From Newton's second law; F = ma and a = F/m. F = force , m= mass, a = acceleration. This implies that smokey mouse can increase its speed by;

Increasing the force acting on the mouseDecreasing the mass of the mouse
