Answer:

Cells differentiation

Explanation:

Even though all diploid cells contain virtually the same DNA set, the process known as cell differentiation determines what genes will be coded for what proteins. Cells differentiate according to the role they are required to play in the body with less specialised cells become more specialised according to the genes being expressed.

Answer:KEYSTONE SPECIES

Explanation:

the ecosystem would be extremely different without the key stone specie or cease to exist complete .

Basically a keystone specie is a specie that helps define an ecosystem and if the specie was to die or cease to exist no other specie can take its place and the ecosystem will have to change radically and it'll be forced to introduce a whole a new habitat because the keystone specie has a huge influence on the food web

EXAMPLE :

A keystone specie could be any specie ranging from plants to fungi

A planet has a mass of 5.97 x 1024 kg and a radius of 6.38 x 106 m. Find the weight of a 65.0 kg person at 1000 km above the sur

mote1985 [20]

<u>Answer:</u> The weight of the person above the surface of a planet is 635.83N.

<u>Explanation:</u>

To calculate the weight of a person, we use the formula:

$w=mg$ ....(1)

where,

w = weight of an object

m = mass of the person = 65kg

g = acceleration due to the gravity of the planet

For the calculation of weight, we need to first find the acceleration due to gravity and for that we use the formula:

$g=\frac{GM}{r^2}$

where, g = acceleration due to gravity = $?m/s^2$

G = Universal gravitational constant = $6.67\times 10^{-11}Nm^2/kg^2$

M = mass of the planet = $5.97\times 10^{24}kg$

r = distance of the person from the planet = $6.38\times 10^6m$

Putting values in above equation, we get:

$g=\frac{(6.67\times 10^{-11}kgm/s^2.m^2/kg^2)(5.97\times 10^{24}kg)}{(6.38\times 10^6m)^2}\\\\g=9.782m/s^2$

Putting this value in equation 1, we get:

$w=65kg\times 9.782m/s^2=635.83N$

Hence, the weight of the person above the surface of a planet is 635.83N.

Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by _______ and the sugars

MA_775_DIABLO [31]

Answer:

Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by endoplasmic reticulum _______ and the sugars are added in ___ ER/Golgi__ apparatus.

Explanation:

The protein part of all glycoproteins are synthesized from polyribosomes that then bind to the endoplasmic reticulum (ER). Then the processing of the sugar groups occurs co-and post-translational in the light thereof continuing in the Golgi apparatus for the N-linked glycoproteins.

There are some proteins that are glycosylated inside the ER and then pass to the Golgi (N glycosylation) and others in the Golgi directly (in case of O-glycosylation)
