Answer:
In the haploid cell, only one pair of sister chromatids are present, whereas in the diploid cell, two pairs of sister chromatids are present.
Explanation:
Chromosomes with their sister chromatids become visible during prophase. A haploid cell has only one complete set of chromosomes while there are two complete sets in a diploid cell. Therefore, prophase in a haploid cell would show the presence of only one pair of sister chromatids for each chromosome. This cell would not have the homologous pair with two pairs of sister chromatids.
On the other hand, the diploid cell would have two homologous chromosomes for one homologous pair. Each of the chromosomes of a pair would have two sister chromatids. Therefore, one homologous pair would have a total of four chromatids or two pairs of sister chromatids.
The best description would be; Vancomycin inhibits cell wall synthesis promoting bacterial lysis. Vancomycin is an antibiotic that is used to treat quite a number of bacterial infections. It inhibits cell wall synthesis and promotes bacterial lysis and the death of the bacteria. It does not contain a beta lactam ring, therefore an effective serum trough level is 10 mcg/mL to 20 mcg/mL depending on the severity of the infection and renal function. The drug is an alternative to use in patients allergic to beta-lactam antibiotics.
The correct answer is chorionic villus sampling.
Chorionic villus sampling is a kind of prenatal diagnosis to find the genetic or chromosomal disorders in the fetus. The transcervical method is done by administering a thin plastic tube via the cervix and vagina to reach the placenta. A small sample of chorionic villus tissue is then withdrawn.
The chorionic villi are the projections of placental tissue, which share the genetic makeup of the baby. The chorionic villus sampling is generally done between the weeks 10 and 13 of pregnancy.
The answer is: beans and whey protein
The most abundant element in the atmosphere is nitrogen N2 (~78%), followed by oxygen O2 (~21%).
CO2 makes up less than 1% of the atmosphere. Much less for that matter.
The key to the question is knowing that protein contains nitrogen.
Protein is a macromolecule made up of smaller molecules called amino acids. Amino acids are made up of a central carbon (C) and 4 groups:
amine (-NH2)
carboxylic acid (-COOH)
a hydrogen (H)
a side chain which is different and specific to each amino acid
One can infer amino acids contain nitrogen from their name (amino).
Beans contain a high amount of protein, and whey protein is a type of protein, so both contain nitrogen.
