Answer:

The Golgi apparatus plays a central role in molecular transport after biosynthesis.

Explanation:

Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.

The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.

In the fungal life cycle, karyogamy results in:______.

Vikentia [17]

Answer:

In the fungal life cycle, karyogamy results in D. fungi haploid nuclei from two parent fungi fuse together

Explanation:

Karyogamy has an important role in sexual reproduction. It is the last step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei. This is the steps that usually follows the Plasmogamy stage. This step is part of the sexual reproduction of fungi too. Karyogamy is key because it helps recombine two different genetic material.

What is the period of a satellite in a circular orbit just above the surface of the Moon? The Moon’s mass is 7.36 × 1022 kilogra

Tanya [424]

Answer:

Explanation:

The satellite revolves around moon due to centripetal force which is provided by gravity in this context so we can equate gravity and centripetal force.

$mrw^{2} = \frac{GMm}{R^{2} }$

where, m is mass of satellite

M is mass of moon

ω is angular velocity

G is Universal gravitational constant

R is the radius of moon

from the above equation we get ω as,

$w=\sqrt{\frac{GM}{R^{3} } }$

$T = \frac{2\pi }{w}$

$T= 2\pi \sqrt{\frac{R^{3} }{GM} }$

here M = 7.36 X 10^22

R = 1.738 X 10^6

G =6.67 X 10^-11

$T= 2X3.14 \sqrt{\frac{(1.738 X 10^6)^{3} }{6.67 X 10^-11 X 7.36 X 10^22} }$

T= 6.50 X 10^3 seconds

The steroid lipid cholesterol is a component of membranes. identify true statements about cholesterol and its role in membrane f

Paraphin [41]

Cholesterol refers to a fat-like waxy substance, which is found in all the cells of the body. The body needs some cholesterol to produce hormones, substances that assist in digesting foods, and vitamin D. The body produces all the cholesterol it requires.

Cholesterol enhances the fluidity of the membrane, which otherwise comprises majorly the long-chain saturated fatty acids.

Cholesterol minimizes the fluidity of the membrane in the regions known as rafts that comprise huge concentrations of cholesterol and sphingolipids.
