Sperms and eggs are haploid and result in the formation of a diploid zygote. Also, sperm can travel to the egg. So only Sperm can fertilize an egg.

<h3>What is the fertilization of an egg? </h3>

The fertilization of the egg results when the sperm from a male partner travels to the egg of the female partner.

The sperms are produced in the male reproductive system by the testis. They are ejaculated in the vagina of the female reproductive system.

They travel from the vagina to the fallopian tube. In the fallopian tube, the egg reaches which is produced by the ovaries. Then, the sperm and the egg meet at the fallopian tube and the egg is fertilized.

Therefore, sperm is able to travel to the egg for fertilization.

What benefits do plants with a smooth stem have? Does the stem type protect a plant?
gogolik [260]
<h3><u>Benefits of smooth stem  over rough stem:</u></h3>

Smooth stem plants like guava, eucalyptus etc do have a smooth layer of bark over its stem that comes out as a skin when they shed their barks. Whereas most of the other plants like mango, banyan etc do have a rough corrugated layer of bark over their stem.

The smooth stem doesn’t let water to accumulate in the bark which can led to infections to the tree. It also doesn’t allow any seed to settle on bark that can led to growth of parasites. Thereby this smooth bark saves the trees from some of the probable harm to the tree.

How do researchers prepare an intron-free copy of a eukaryotic gene for use in creating transgenic bacteria?
Tcecarenko [31]

The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA

The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.

Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

One of the many tests done during urodynamic studies is the sphincter electromyelogram. What does this test study
eduard

One of the many tests done during urodynamic studies is the sphincter electromyelogram. This test studies activity of the voluntary muscles of the perineal area.

  • Patients with urine incontinence or other symptoms of the lower urinary tract can be diagnosed with urodynamic testing.
  • Both men and women take these examinations. Nerve and muscle function are measured by urodynamic testing.
  • Clinically, perineal sphincter electromyography may be helpful in assessing individuals with bowel, urinary, and sexual dysfunction.
  • All patients with a history and clinical examination that point to a central or peripheral sacral neuropathic lesion should be given this option.
  • The pudendal nerve innervates the external sphincter (EAS), which is the best muscle for identifying neuropathic lesions in lower sacral myotomes.
