Answer:
1. 5 pg of DNA.
2. 10 pg of DNA.
Explanation:
The process of meiosis results in the production of the four haploid daughter cells and is involved in the formation of sexual gametes. The sperm cells produced as a result of the meiosis are haploid in their ploidy and therefore contains only "C" amount of DNA.
<u>1. During interphase
</u>
The sperms are formed from the diploid spermatocytes which contain 2C amount of DNA. During the cell cycle before the M phase, cell replication takes place in the S phase. The synthesis phase doubles the amount of DNA and forms 2C to 4C.
Therefore before the S phase or in G1 phase, the DNA amount will be 2C or 2 x 2.5= 5 pg of DNA.
<u>2. At metaphase
</u>
After S phase, the amount of DNA increases to 4C which gets distributed during the anaphase that is after the metaphase. Therefore, the amount of DNA during metaphase will be 4C or 4 x 2.5 = 10 pg.
Answer: "electr"
The word part that completes the medical term meaning process of recording the electrical activity of the heart, is electr/o/cardi/o/graphy,
Explanation:
Electrocardiography is the science behind the diagnosis of the heart rhythm and conditions based on the visual presentation of the electrical currents associated with heart muscle activity.
Thus, it helps in understanding and diagnosis of some irregular heart rhythm and abnormalities.
This statement is false.
<span>Gynoid fat (“pear-shaped fat”) is the body form with fat around the hips, breasts and thighs. It is not associated with diseases as android fat.<span>
Android fat ("apple-shaped fat”) refers to the distribution of human adipose tissue around the trunk in areas such as the abdomen, chest, shoulder and nape of the neck. It is also called central obesity. Diabetes and gout are diseases often related to central obesity.</span></span>
An hypothesis is a possible explanation for a set of observations or answer to a scientific question. A supposition or proposed explanation made on the
basis of limited evidence as a starting point for further
investigation.
And practically, an hypothesis is used as the basis for further experiments, where the hypothesis is rigorously tested under varying conditions. The hypothesis that is tested and modified under different conditions may become a general
theory
.The hypothesis that has the least number of variables sufficient to explain the phenomenon is preferred.
