The correct answer is - option 2. (chemical structure of the nucleotide)

Explanation:

Nucleic acid, DNA and RNA stores genetic information which helps in produces various proteins and for the next generation of the cells. Nucleic acids are made up of monomers of nucleotides joined together to form the nucleic acids. Each nucleotide has sugar, a nitrogenous base, and phosphate in the structure that joined to form a helix structure.

Thus, the correct answer is - option 2.

Answer:

Explanation:

2

Answer:

Explanation:

Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

Explanation:

Water biomes describe all the living things living in an area of water such as a lake or ocean. The surrounding environment plays a huge part in what organisms able to live there.

For example, green plants and algae require sufficient sunlight and oxygen to perform photosynthesis. Green plants and algae are an important food source for many other organisms. The amount of salt is important for various fish, as they will be unable to survive in very high salt concentrations. Therefore, all of the above are limiting factors.

Answer:

If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.

Answer:

A

Explanation:

Plants use water in the process of photosynthesis, (to make food) but they don't need all of it. They use carbon dioxide, the stuff people and animals breath out, and release oxygen for us to breath, then we breath out carbon dioxide again and the process happens again.

Fun fact: Did you know that rain forests make their own weather? Plants not only release oxygen into the air, but tiny droplets of water. (water vapor, and this part of the water cycle is called transpiration) Those droplets condense and form clouds. That's why it rains every day in tropical forests. Cool huh?

Explanation:

The zones of the ocean which is most hospitable to life is the epipelagic zone. Thus, the correct option will be A.

The Epipelagic zone can be referred to as the uppermost layer of the ocean. Epipelagic zone is located between the surface and the 600 feet in depth of the ocean. The Epipelagic Zone is also known as the Sunlight Zone. It is the region of the ocean which sits on the continental shelf in the oceans.

Epipelagic zone is in this thin layer which the process of photosynthesis takes place. The epipelagic zone of the ocean only represents about 2 to 3% of the entire ocean zone, beyond this zone, light is too dim for the process of photosynthesis to occur. This is the reason why, the epipelagic zone is the most hospitable zone of the life in oceans.

Therefore, the correct option will be A.

A biologist added a 10% salt solution to the slide and observed the cell as shown in diagram B. The change in appearance of the cell resulted from

According to the complete diagram, we can see that there is a transport between cells as there is a change in appearance as the biologist added a 10% solution to the second cell.

As a result of this, we can see that through the rigid cell wall, vacuole and cytoplasm, there are mechanisms for transport as it allowed more water to move out of the cell than into the cell which caused the shrinkage.

Therefore, the correct answer is option D

Explanation:

Molecules of tRNA exist free in the cytoplasm of cells. When protein synthesis is taking place, enzymes link tRNA to amino acids in a highly specific manner. The third form of RNA is messenger RNA (mRNA), which receives the genetic code from DNA and carries it into the cytoplasm where protein synthesis takes place.

What is Hydrogen Bonding?

Hydrogen Bonding is the interaction between Hydrogen atoms, with their molecules, due to the fact that their (Hydrogen atoms and bonds) are weak that even the other types of bonds are stronger.

(The other bonds are: covalent and ionic bonds)

(Hydrogen bonds are weaker than the average bonds listed above)

If you are to take how and why hydrogen bonds effect/affect ice cubes, we would have to look at how ice cube are formed. If you know, ice cubes can be created due to low temperatures (cold temperatures) making water into a solid. When ice cubes form into a sold, the spacing of the molecules become further apart, creating the density of the overall ice cube lighter than it was allowing it (ice cubes) to float.

Explanation:

In a Venn Diagram that compares and contrasts the different characteristics or features of the produced plants, "cloning" would be in the epicenter. This is because through the process of "cloning" you are basically copying the core genetic makeup of the plant and creating a brand new plant that shares all of the exact same characteristics and features as the plant's whose genetic makeup was used as a baseline.

That's the correct answer.

The process that binds together sediment to form new rock is cementation. The correct option is A.

Cementation is the process of mineral materials precipitating in the pore spaces to harden and weld clastic sediments (those generated from preexisting rock pieces). It is the final phase of sedimentary rock formation.

Through cementation, sediments become sedimentary rock. In the spaces between the sediment particles, this action causes the precipitation of minerals.

Examples of cementing include carbonate hard ground and beach rock. Black rock is a particular kind of rock that develops along the shore and is composed of a wide variety of sediment types and sizes that have been cemented together.

Therefore, the correct option is A. cementation.
