There's 39 chromosomes in the sperm cell. Why? Because sperm cells are gametes and therefore they are haploid cells meaning they have half the number of chromosomes of a regular cell or diploid cell.
78 / 2 = 39
<span>The 5' end
During transcription, new nucleotides are added to the 3' end of the molecule due to the arrangement of the nucleotide with the new nucleotide being added to the hydroxyl group at the 3' position of the ribose.</span>
Answer:
See the answer below
Explanation:
First, the image tells that chromosomes are made up of genes or that genes are located on chromosomes. It further showed that genes are translated as proteins in the cell and this protein respectively control the expression of traits.
Secondly, it also showed that during sexual reproduction, the offspring produced usually have the same proteins as the parent and therefore have exactly the same traits as the parent. Only one parent is needed for asexual reproduction.
<u>However, two parents are needed for sexual reproduction where each parent donate chromosomes containing gene to the genome of their offpsring. The mixture of genes ensures that the offspring look different from the parent.</u>
<em>The image further showed that asexual reproduction does not lead to any variation while sexual reproduction leads to variation of the offpsring from their parents.</em>
Answer: Active transport
Explanation: requires the cell to spend energy, usually in the form of ATP. Examples include the transport of large molecules (non-lipid soluble) and the sodium-potassium pump. Types of active transport.
Oh! Just did this in school!
Eukaryotic cells are more complicated than prokaryotic. Eukaryotic cells have DNA in their nucleus, they have more than one chromosome, lysosomes, preoxysomes, mitochondria, cytoskeleton, golgi apparatus
