I believe its Uranus and Neptune, please tell me if I'm wrong.
Reason: an ice planet is made up of a semi icy surface like perhaps water, oxygen, or any other element stronger than hydrogen. Neptune and Uranus both meet this match, they are made up of elements that are actually stronger than hydrogen.
The statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes (option C).
<h3>What is the plasma membrane?</h3>
Plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semi-permeability of the plasma membrane means it allows some molecules through but blocks other substances.
The plasma membrane is the cellular structure that protects and encompasses the cell's content.
All living organisms possess the plasma membrane, which is also called cell membrane.
Therefore, the statement that is correct about plasma membranes is that both plant cells and animal cells have flexible plasma membranes.

Answer:
Bacteria do not possess the tendency to withdraw sequences of introns from a gene, thus, if the gene for the human growth hormone were transcribed, it would translate into a non-functional protein.
When the expression of a gene takes place in eukaryotes, the budding mRNA comprising introns are removed consequently at the time of post-translational processing to produce mature mRNA. Also, the human growth hormone is produced by the pituitary gland in the form of a pre-hormone comprising a leader peptide of about 20 amino acids in length, which need to get removed post-translationally to produce a mature functional protein.
Bacteria do not possess the biochemical machinery either to effectively withdraw the leader peptide after translation or to splice out the introns. Thus, when an unchanged human growth hormone is cloned, the bacteria cannot produce the functional human growth hormone.
Answer: 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.
Explanation:
Heterozygous means that its genotype has two distinct alleles, i.e. a dominant and a recessive one. So the genotype of the plants is Pp, and each plant has two alleles since<u> they are diploid organisms, which have two copies of each gene.
</u>
<u>Each plant produces gametes, which are haploids cells. That is, they only have one copy of each gene (one allele)</u>. So, the gametes produced by Pp have a P or p genotype. During fertilization, the maternal and paternal gamete are fused to form a diploid zygote where their genotype will have one allele from the father and one from the mother.
By making this monohybrid cross, we cross the gametes of each parent in the punnett square (see picture)
In the offspring, we see one PP genotype (homozygous dominant), two Pp genotypes (heterozygous) and one pp genotype (homozygous recessive). <u>Since we know the P allele is dominant and it codes for purple color, a genotype only needs one P allele to express that phenotype</u>. So Pp and PP organisms are purple, and only pp is white. That means 75% of the plants are purple and 25% are white. The phenotypic ratio can be expressed as 3:1.
Answer:
During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.
