the phenomenon of the unequal separation in the meiosis is called as nondisjunction. If the nondisjunction causes the missing chromosome in a haploid gamete, the diploid zygote it forms with the another gamete will then contain only one of the copy of that chromosome from the other parent, this condition is known as monosomy.

The term "monosomy" is used to describe the absence of one of the member of the pair of chromosomes. Therefore, there are about 45 chromosomes in each cell of the body instead of that usual of 46.

Turner syndrome is the only and full monosomy that is seen in the humans — all other cases of the full monosomy are the lethal and the individual will not about survive development.

For each of the following features of nucleic acids, indicate whether it is true of DNA only, of RNA only, of both DNA and RNA,
suter [353]

Answer:

Nucleic acid is one of the four major macromolecules that is present in all life forms. It includes DNA ( deoxyribonucleic acid) and RNA (ribonucleic acid). It is made up of small unit called nucleotides.

A nucleotide contains a pentose sugar that is deoxyribose in DNA and ribose in RNA, nitrogenous base that is Adenine, Thymine, Cytosine, Guanine in DNA and Adenine, Uracil, Cytosine, Guanine in RNA, and a phosphate group.

It is synthesised by a process of comlementary base pairing ( such as in double stranded DNA, A pairs with T and G pairs with C).

DNA is converted to mRNA inside the nucleus of eukaryotic cell and mRNA is then translated to protein when it moves the cytosplasm of the cell.

Thus, the correct answers are as follows-

1) Is an inherently directional molecule, with an N-Terminus on one end and a C-Terminus on the other end - true neither for RNA or DNA.

2) Contains the base adenine- True for both DNA and RNA.

3) Contains the nucleotide deoxythmidine monophosphate- True for DNA

4) Occurs only in signle stranded form- True for both RNA and DNA( such as single stranded DNA in DNA virus, and RNA in single stranded RNA in AIDS virus).

5) Is synthesized by a process that involves base pairing- True for both DNA and RNA.

6) Is involved in the process of protein synthesis in the cytoplasm of the cells in the liver- True for RNA ( particularly messenger RNA, mRNA)

Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia?
timama [110]

Answer:

The correct answer is option d. "India was a separate continent until 45 million years ago".

Explanation:

135 million years ago, Pangea was a single continent that became separated into Laurasia in the north and Gondwana in the south. India was part of Gondwana along with Australia, South America, Antarctica and Africa. However, as a result of tectonic activity India got separated from Gondwana. This period of time at which India was a separated continent is the factor that most likely explains why animals and plants in India differ greatly from species in nearby southeast Asia. At being a separated continent, India's plants and animals go through an independent evolutionary process which made them very different an unique from nearby species.

If the speed of a wave decreases but the wavelength remains the same, what must be true of its frequency?
ladessa [460]

The frequency increases.


Here's an easy way to think about this. The wavelength is the distance from crest to crest, or trough to trough -- equivalently, it's the distance the wave travels in one period. This means that the speed of the wave is the wavelength divided by the period, or <span><span>v=<span>λT</span></span><span>v=<span>λT</span></span></span> . But the frequency is just the reciprocal of the period, so <span><span>v=λf</span><span>v=λf</span></span>. Clearly, if v increases and the frequency stays the same, the wavelength must increase by an equivalent factor.

(Image attached) Please help. Question is in the attached image.
kifflom [539]

Answer:

All of the above

Explanation:

ATP synthase is a transmembrane protein enzyme. It harnesses the potential energy –proton motive force-  created by the development of a proton gradient across a membrane (could be across the intermembrane space in chloroplast and mitochondria). As the H+ ions 'drain' back and pass through their channels in the protein enzyme, the synthase is able to phosphorylate ADP and Pi to form ATP.

These ATPs (from photophosporylation) in light-dependent phase, are used in the catabolism of glucose, in the light-indepedent phase.
