Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

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.
