The correct answer is option A. Carrying the genetic code and determining an organism's structure and function are the functions of DNA. It is the hereditary material in almost all other organisms. The information in a DNA is stored as codes that is composed of chemical bases.

How are earthworms and fish similar?

dimaraw [331]

Materials eliciting increased tongue flicking and prey attack in garter snakes were isolated from both earthworm and fish prey. New extraction methods based on chloroform-methanol mixtures are valuable adjuncts to the more typical aqueous preparations. Both high- and low-molecular weight components from earthworms and fish were active. The similarity between the active chemicals in these two classes of prey was established using several methods of analysis.

Describe the stages of each type of cell reproduction process from a normal patient whose body cells can repair themselves and n

Citrus2011 [14]

The types in which cell divides are:

I. Mitosis: Mitosis is the type of cell division in which the DNA and chromosome number of the daughter cell remains the same as parent cell (2n).

Different stages of mitosis are:

a. Prophase - disappearance of nuclear membrane takes place and chromosome starts to condense.

b. Metaphase - The Chromosome aligns to the equatorial plane and gets attached to the spindle fibre arising from the centrioles through its centromere.

c. Anaphase - The sister chromatids of a chromosome gets separated and starts moving to opposite poles.

d. Telophase - Nuclear membrane reappears and the cells divide.

One example where mitosis takes place is to repair the part of the body where it has got injured.

II. Meiosis: Meiosis is the type of cell reproduction where the daughter cell have half the number of chromosome and DNA content than mother cell. Meiosis takes place in two stages and they are:

i. Meiosis I - It includes following stages:

a. Prophase I - Nuclear membrane disappears and chromosome starts to condense.

b. Metaphase I - The homologous chromosome aligns to the equatorial plane and gets attached to the spindle fibre arising from the centrioles through its centromere.

c. Anaphase I - The homologous chromosome gets separated and starts moving to opposite poles.

d. Telophase I - Nuclear membrane reappears and the cells divide.

Meiosis I leads to the formation of two daughter cells.

ii. Meiosis II - It includes following stages:

a. Prophase II - disappearance of nuclear membrane takes place and chromosome starts to condense

b. Metaphase II - The Chromosome aligns to the equatorial plane and gets attached to the spindle fibre arising from the centrioles through its centromere.

c. Anaphase II - The sister chromatids of a chromosome gets separated and starts moving to opposite poles.

d. Telophase II - Nuclear membrane reappears and the cells divide.

Meiosis II leads to the formation of four daughter cells having haploid number of chromosome.

If you tagged organic carbon inside a chloroplast with a fluorescent label, the location most likely to have a high concentratio

podryga [215]

The answer is; in the stroma. The chloroplast is the organelle inside the plant cell that performs the process of photosynthesis. Photosynthesis contains two kinds of reactions, the first is the light reactions which happen in the grana as it contains chlorophyll which absorbs light energy. The products of the light reactions are used to fix carbon dioxide in the second reactions which are the dark reactions. The dark reactions happen in the stroma outside the grana. Therefore, the stroma contains more carbon.

What is the relationship between a mineral and a rock?

netineya [11]

Minerals are composed of multiple elements and rocks are actually made up of minerals. Take quartz for example, it's a mineral that's made up of silicon and oxygen. If we then look at the igneous rock that is referred to as granite, we'll see quartz (the main one), mica(s), and feldspar.

So your answer is B. :)
