Sarah is finishing a model drawing of a cell. She adds a membrane to the nucleus on her model. The nucleus of a cell has a membrane that isolates
material inside of it from the rest of the cell. Why does the nucleus need a membrane?
A.
The membrane helps the nucleus to create energy for the cell.
B.
The membrane helps the nucleus to create proteins for the cell.
C.
The membranes helps the nucleus to remove waste from the cell.
D.
The membrane helps the nucleus protect genetic material for the cell.

Answers

Answer 1

Answer:

C

Explanation:

a nuclear membrane is a double membrane that encloses the cell nucleus. It serves to separate the chromosomes from the rest of the cell. The nuclear membrane includes an array of small holes or pores that permit the passage of certain materials such as nucleic acids and proteins, between the nucleus and the cytoplasm .

Answers

Answer:

75% purple and 25% white

Explanation:

When a punnett square is drawn to predict the phenotypes of the pea plants offspring:

- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)

- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)

_____________________________________

[tex]\Large\textbf{Phenotype:}[/tex]

It is the physical appearance of the trait, whether the plant has Long stem or short stem.

[tex]\Large\textbf{Genotype:}[/tex]

A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.

_____________________________________Alleles:

Allele Long stem A is dominant over short stem a

Genotype of Parent Pea Plants

Pea Plant 1 has genotype Aa

Pea Plant 2 has genotype aa

_____________________________________[tex]\Huge\text{Question:}[/tex]

The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.

Heterozygous Plants

Heterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.

If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3

Answers

Answer:

Genes are always passed from offspring to parents

Explanation:

Well parents pass on genes to an offspring for one for another the parent will not always pass a gene for a certain trait on, if the trait is not a dominate gene it has the chance of getting replaced by the other parent's more dominate trait

Meiosis creates two daughter cells that have identical genetic information to the parent cells.

Answers

Search I’m safari there is the answer I think

Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.

What is Meiosis?

Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.

Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.

Therefore, the correct option is C.
