Which is a function of nucleic acids​

Answers

Answer:

Nucleic acids are important because they make up genetic information in living things. There are two types of nucleic acid and they are DNA and RNA. DNA is the basic instructions for living things. It is passed down from parent to offspring and is found in the nucleus of the cell.

Explanation:

Answer:

store genetic information

Explanation:

does Sexual reproduction relies on meiosis instead of mitosis because only meiosis produces diploid sex cells.

Answers

Yes, meiosis is strictly dealing with your gonads which are your gametes (testes/ovaries). It would not produce a diploid sex cell but rather 4 totally genetically different haploid cells. It can best be seen as 2n becomes n. In mitosis you can have 1n to 1n or 2n to 2n because in mitosis you have 2 identical daughter cells exactly like the parent cell.

In which situation would new technology be most likely to cause a change in an existing theory about new structures in a cellThe new technology makes it possible to detect and analyze a structure more rapidly
The new technology allows scientists to confirm the presence of an existing structure in a cell
The new technology makes it possible to produce additional structures that were not previously there,
The new technology allows detection of a structure that could not be detected previously

Answers

Answer:

D. The new technology allows the detection of a structure that could not be detected previously.

Explanation:

The theory is developed based on real things. But theory can be changed. No theory exists forever. Now, if a theory is developed in biology from exiting components of the cell, then if any new elements discovered in the cell, later the previous theory can be changed at any time. So, if any new technology arrives, which can detect the structure of a cell which wasn't found before, that causes change or modification of an existing theory.

Explanation:

A few hundred red deer were introduced, in 1998, into a prairie ecosystem where they faced no natural predators. The graph shows the subsequent variation of the deer population in a certain area of the prairie. Explain, using the concept of carrying capacity, the observed variation of the deer population over time.

Answers

The carrying capacity is the maximum size of some population. It represents the number of animals that can live, reproduce, survive in the given area regarding the indefinite sustainability of this area in terms of resources (food, water, habitat, etc.). When animals are introduced into some area, the resources are abundant. But, as the number of animals in the population grows, the resources reduces. Once the population reaches the carrying capacity the growth of population will stop (on the graph in the year 2002). With reduced resources, the competition for resources will increase, and also, animals are more prone to predators and diseases. All of this will decrease population size for a bit (on the graph year 2003).
