Damage to sensory receptor cells would most likely result in ________. I. confusion of visual and auditory input II. inaccurate

MatroZZZ [7]

Answer:

The correct answer is: None of the above. The accurate answer is: Problem or inability in detecting the sensory information.

Explanation:

Sensory receptor cells form the part of the sensory epithelial layer that are present in the form of a lining in all sensory organs.
These sensory cells possess some specialised receptor molecules, usually on the surface of the cells, that can sense different types of sensory signals like light, in case of eyes, smell is case of nose, taste in case of tongue and sound in case of ears.
Any damage caused to these cells will adversely affect their capability to perceive or receive or detect the sensory signals.
Option I is incorrect because sensory cells are not only present in the eyes and ears but also in nose, tongue, skin. The activity of the sensory cells of one organ is independent of the activity of sensory cells of other organs hence, damage to the sensory cells of one organ will not create any confusion in different sensory inputs.
Option II is incorrect because integration of all the sensory impulses occur in the brain after the impulse has been received and detected by multiple sensory receptor cells and send to the brain through the sensory neurons.

The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. this would result in

xxMikexx [17]

Answer:

The binding of a neurotransmitter on a postsynaptic cell allows potassium ions to diffuse out of the cell. This would result in a NEGATIVE CELL MEMBRANE POTENTIAL which is an HYPERPOLARIZATION event.

Explanation:

The binding of a neurotransmitter to a postsynaptic cell results in a group of channels in the cell membrane called ligand gated channels open or close in response to that binding.

Hyperpolarization occurs when a ligand gated channel opens and allows potassium ion to flow out of the cell.

During hyperpolarization, potential of the cell membrane experience changes which makes it to become more negative.

Describe what it means for a field of study to be considered a science

Artist 52 [7]

Explanation:

In general, field of study refers to gaining the knowledge in a particular branch. On the other hand, science means the system where we can attain the knowledge about the universe. This always delivers with theoretical and experimental descriptions in a detailed manner about natural phenomenon.

This handles with each and every aspects about living organisms and environment. This paves the way to know more details in particular part. Hence, field of study like physics, engineering also referred a science in this manner.

How are cells with monosomy different from haploid cells

gladu [14]

Haploid refers to a cell that has has only one copy of each chromosome, like in a gamete such as a sperm cell or egg cell. Upon fertilization, the two haploids come together to form a full diploid cell (two copies of each chromosome) which then goes on to form the complete organism. Monosomy refers to a condition where there is only one copy of a specific chromosome. For example, in the human condition Turner Syndrome, there is only one X chromosome, instead of two sex chromosomes. Most incidences of monosomy other than Turner Syndrome are lethal, so there aren't many examples of it.

Mars had an orbital period of 1.88 years. In two or more complete sentences,explain how to calculate the average distance from m

Vanyuwa [196]

This is an interesting problem involving astronomy, in fact, simple physics.
Let r=distance of sun to mars, in metres

Mars had an orbital period of 1.88 years.
=>
tangential velocity, v, of the planet, in m/s is
$v=\frac{2\pi{r}}{T}$
 $=\frac{2\pi{r}}{1.88*365.25*86400}$ m/s, accounting for leap years
$=3.371*10^{-8}\pi{r}$ m/s

The centripetal force, Fc, generated is
$Fc=\frac{mv^2}{r}$
where m=mass of mars = 6.39*10^(24) kg
$=\frac{mv^2}{r}$
$=\frac{6.39*10^{24}v^2}{r}$
$=7.26168*10^9\pi^2r$

The gravitation pull from the sun, Fg, is given by
$Fg=\frac{GMm}{r^2}$
where G=grav. const., =6.67408*10^(-11) m^3 kg^(-1) s^(-2)
M=mass of sun=1.989*10^(30) kg
$=\frac{6.67408*10^{-11}1.989*10^{30}6.39*10^{24}}{r^2}$
$=\frac{8.4826*10^44}{r^2}$

Since the radial distance is in equilibrium, the average distance, r can be found by equation Fc=Fg and solving for r:
Fc=Fg
=>
$7.26168*10^9\pi^2r=\frac{8.4826*10^44}{r^2}$
Solving for the real root:
$r^3=\frac{8.48256*10^44}{7.26168*10^9*%pi^2}$
$=\frac{1.1681263*10^{35}}{\pi^2}$
=2.279*10^11 m
