It could cause them to catch animal disease

Explanation:

Xenotransplantation refers to the transplantation of organs or tissues between different species. E.g. Chimpanzee organ (liver) being transplanted into a human body would come under the category of xenotransplantation.

Pigs have come up as prospective organ donors since their organs and tissues are more or less to that of human’s. However, there are issues such as-

Xenotransplantation of pig’s tissue into a human would allow easier passage for all types of zoonotic viruses.
Moreover, if transgenic pigs are used instead of natural pigs it can lead to virus mutation as per the human body demands thus leading to increased susceptibility to human infection.

Thus, engrafting of pig’s tissue in the human body poses a significant risk for humans of catching a zoonotic (animal) disease.

Which of the following factors will negatively impact the rate of diffusion of a molecule?

Maurinko [17]

Answer:

A low difference in the concentration of the molecule across the media

Explanation:

Diffusion is a type of passive transport where the molecules move in the influence of concentration gradient of diffusing molecules i.e. from the higher concentration region to the lower concentration region. There are some factors which affect the rate of diffusion, these are written below -

Mass of diffusing molecule - lighter molecules diffuse faster and heavier one diffuse relatively slower.
Concentration gradient - rate of diffusion is higher if the difference in concentration of the diffusing particles is larger in the two regions.
Distance traveled - molecules diffuse faster if they need to travel little distance during diffusion.
Temperature - rate of diffusion will be greater at higher temperatures because the movement of diffusing molecules gets increased.
Solvent density - rate of diffusion tend to be lower if the solvent has higher density.

Looking at these factors we can conclude that the second statement in the question tells about a negative impact regarding the diffusion because due to low difference in concentration across the two media, the rate of diffusion will be lower.

Two objects, A and B, each of mass o.22 kg, are moving at 0.34 m/s directly toward each other. What is the speed of Object A aft

ki77a [65]

Theoretically, if the objects have the same mass and are moving towards each other at a speed of $0.34m s^{-1}$ , after a perfectly elastic collision, the object A is supposed to move with the same velocity in the opposite direction.

The gnaphosid spider Drassodes cupreus has evolved a pair of lensless eyes for detecting polarized light. Each eye is sensitive

BartSMP [9]

Answer:

Part A

The intensity is $I = 618 W/m^2$

Part B

The intensity is $I_1= 81.884 W/m^2$

Explanation:

From the question we are told that

The intensity of the light detected by first eye is $I = 700 W/m^2$

Now at initial state according the question the light ray is perpendicular to the eye so it means that it is at 90° the eye

Now the first question is to obtain the intensity the first eye (the first in this case is the one focused on the light )would detect when the head is rotated by 20° its previous orientation

This is mathematically evaluated as

$I = I_i cos^2 ( 20^o)$

$I = 700\ cos^2 (20)$

$I = 618 W/m^2$

Now the second question is to obtain the intensity the first eye (the first eye in this case is the one that is not focused on the light )would detect when the head is rotated by 20° its previous orientation

Now in this case the angle between the eye and the light is 90-20 = 70°

$I_1 = 700 \ cos^2 (70)$

$I_1= 81.884 W/m^2$
