Which of the following correctly identifies the types of cell division describe in rows x and y

Biology
1 answer:
Juliette [100K]3 years ago
6 0

Answer:

B. Row x describes meiosis and row y describes mitosis

Explanation:

  • <em><u>Mitosis is the process in which a cell divides to yield two daughter cells with same number of chromosomes as the parent cell. </u></em>The process takes place in the somatic cells or the body cells. For example, a cell with 14 chromosomes divides to produce two cells with 14 chromosomes.
  • <em><u>Meiosis on the other hand is the process in which a cell divides into four daughter cells that have half the number of chromosomes as the parent cell.</u></em> The process takes place in the germ line cells where gametes are produced. For example a cell undergoes meiotic division to produce four cells each with 7 chromosomes.

Which of the following statements is/are true of long noncoding RNAs? Choose one or more: a. They can trigger the activity of hi
Alinara [238K]

Answer: Options A, B, C and D are correct.

Explanation: They can trigger the activity of histone acetyltransferases.

These RNAs functions by binding to histone-modifying complexes, to DNA binding proteins (including transcription factors), and even to RNA polymerase II.

They can silence genes by promoting the formation of euchromatin by arranging hetero- or euchromatic regions into close proximity may stabilize these domains or it may control the spreading of post-translational modifications (PTMs) to nearest chromatin.

They are actively involved in X chromosome inactivation.

They can regulate the translation and stability of mRNAs.

In Eukaryotic cells RNA transcription is a closely regulated process. Transcription of a lncRNA may regulate the transcription of nearby mRNA genes, either positively (maintaining active chromatin structure) or negatively (for example, colliding polymerases). In these cases, the RNA product may have no importance at all, or it could have an additional function.

Please help me with question 72
romanna [79]
A. A reason for the increased use of electricity is the increasing population; more people are being born, more people are using electricity.

b. A strategy to reduce the amount of fossil fuels is for more people to use electric cars where the electricity is sourced naturally. Perhaps the government could implement a system where drivers of electric cars could be rewarded.

which information must be known about a compound to find the molecular formula from the empirical formula​
LenKa [72]

Answer:

Molecular mass or vapor density

Explanation:

The empirical formula is the simplest formula of a compound. The molecular formula expresses the exact formula of the compound. To derive the molecular formula, we need information about its molecular mass or if given the vapor density.

                (Empirical Formula)n = Molecular formula ------(i)

         n = number of repeating units of the empirical formula present in one                        mole of the molecule

          also, (molar mass of empirical formula)n = molar mass of compound

      From here, we can find n and insert in (i) above.

Can someone help me with this, also brainliest.<br> PUNNETT SQUARES
user100 [1]

Explanation:

G- green feathers

g- yellow feathers

L- long beak

l- short beak

Letters are the easiest way of modeling a Punnett square. The big letters mean it's dominant, while the lower case means it's recessive. Dominant traits will show up over the recessive traits. The answer is 75% because if the female is heterozygous, her alleles would be Ll, and as I said before, the big letters take over the little letters in any case.

I hope this helps :)
