<u>Mitochondria:</u> carry out cellular respiration.
<u>Chloroplasts:</u> carry out photosynthesis.
<u>Mitochondria:</u> found in plant and animal cells.
<u>Chloroplasts:</u> produce carbohydrates used as source of food for most living things.
<u>Mitochondria:</u> abundant in human muscle cells.
<u>Chloroplasts:</u> not found in animal cells.
<u>Chloroplasts:</u> contain chlorophyll.

A cell can be defined as the fundamental functional, structural and smallest unit of life, which is found within the body of an organism.

Some examples of cell organelles that are found in the body of an organism include the following:

Nucleus.
Endoplasmic reticulum (ER).
Vesicles.
Cytoplasm.
Cell membrane.
Chromosome.
Golgi apparatus (bodies).
Chloroplast

<h3>What is mitochondria?</h3>

Mitochondria can be defined as one of the cell organelles that is found in the body of a living organism.

Also, mitochondria is known as the powerhouse because it is saddled with responsibility of providing all the energy required in the cell, especially by transforming energy forms through series of chemical reactions.

Base your answer to the question on the passage below and on your knowledge of biology

Delvig [45]

Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.

Explanation:

When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had developed different beak structures. The second sentence best describes as an ecosystem.
An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
An ecosystem is a community of living organisms related with the nonliving components in the environment, together interacting as a system.
its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.

Which of the following descriptions about RNA is not correct?

gayaneshka [121]

Answer:

The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".

Explanation:

Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.

Which planet appears to be rotating on its side

katrin2010 [14]

Answer:

Uranus

Explanation:

A new study finds that the same impact that knocked Uranus sideways may have also created the planet's moons. ... However, Uranus is an oddball in that its axis of spin is tilted by a whopping 98 degrees (relative to the plane of the solar system), meaning it essentially spins on its side.
