Answer: A) Mitochondria and chloroplasts are found in prokaryotes.

Explanation:

Both mitochondria and chloroplasts contain their own DNA and ribosomes.  The first endosymbiotic event occurred: The ancestral eukaryote consumed aerobic bacteria that evolved into mitochondria. In a second endosymbiotic event, the early eukaryote consumed photosynthetic bacteria that evolved into chloroplasts.

Yuri [45]

Answer:

1. polarity

2. hydrogen bonding

3. High heat capacity

4. Adhesion

5. polarity

6. surface tension

7. high heat vaporization

8. hydrogen bonds form a rigid and stable network

9. Water is a polar substance and fat is a nonpolar substance.

10. Cohesion

Explanation:

Water is a polar molecule that is held together by hydrogen bonds to form strong cohesive forces. This accounts for the surface tension in water. Surface tension is the force acting on water that it makes to behave like a stretched elastic skin.

The polarity of water accounts for the fact that it is found in several parts of the body where it largely plays the role of a polar solvent.

High heat capacity of water enables it to function well in the area of thermoregulation in the body. High heat vaporization accounts for the fact that water helps maintain extreme temperature changes in an area.

When in solid state, the hydrogen bonded network in water becomes rigid and forms a very stable network of water molecules. Being polar, water does  not interact with fat because like dissolves like.

In plants, the attachment of water to plant roots is known as adhesion and is necessary for the capillary movement of nutrients to plants via the root.

What<br> is added to make RNA?
Anarel [89]
Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine (Figure 3). ... (Remember, DNA is almost always in a double-stranded helical form.)

What is the difference between static and current electricity? give an example of each
Alenkasestr [34]
Static Electricity - the word static means 'at rest' - this kind of electricity exists when objects separated by an insulator has a build up of opposite charges. Because the attraction between these charges is so strong, they can flow even through great insulators. Ex: lightning, friction

Current Electricity - it makes electronic devices possible. There is a constant flow of charges in this type of electricity. In contrast to static electricity, current electricity is changing, dynamic and always on the move. Ex: starting a car, watching TV, using an electric stove.
