Answer:

C. Is a repeated sequence of DNA in a non- coding sequence

D. Can be composed of a variable number of repeats in different people

Explanation:

Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR <em>loci</em> which are used in forensic identity testing.

Which of these statements is true about autotrophs, but not heterotrophs?

The third one,
Autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.

2.centriole  is matched with  a.

3.interphase is matched with j.

4.furrowing  is matched with h.  

5.anaphase  is matched with g.

6.spindle apparatus is matched with f.

7.chromatin is matched with i.

8.haploid is matched with c.

9.meiosis is matched with e.  

10.homologous chromosomes is matched with d.


Cell division consists of the formation of two or more cells from a single cell, which ensures their numerical growth. During mitosis of a cell, each daughter cell is identical to the mother cell. During meiosis, the mother cell gives two haploid daughter cells with n chromosomes, then each of these daughter cells give two n chromatid cells.

May be some word in this exercise are not very common like:

The mitotic spindle, allows chromatid migration during cell division.

The dividing groove is the invagination of the cell surface that allows the cell to divide in two.

Centriole is a specific cell element of animal cells, which form the centrosomes located at both poles of the cell.

False

Elastic collision is one where two colliding particles both lose some of the kinetic energy. gases tend to have lower densities than solids because gases have lower molar mass. ... if a gas and a liquid are both at the same temperature, the particles of gas have a higher average kinetic energy.
