A molecule that has regions of partial positive and partial negative charge

Biology
1 answer:
nasty-shy [4]3 years ago
7 0

Answer:

A) polar

Explanation:

Polar molecules contains  partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.

For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.

Hence, the correct answer is "A) polar".

Mice21 [21]
<span>The right answer is D. males have only one copy of the X chromosome.

</span>Hemophilia is a rare hereditary bleeding disorder disease. The blood of hemophiliacs does not coagulate normally. Bleeding is not more important, but without treatment, they can be more frequent and last longer than normal. Hence the importance of good monitoring and good treatment.
<span>The 2 types of hemophilia A and B are recessive and X-linked, but a third of hemophilia correspond to a de novo mutation. It is observed that a man who wears the X is always affected by the disease (because he has only one X chromosome in its genome) whereas the woman is only a carrier (she has two X chromosomes, so it can carry a safe X and a mutated X without being attempted by the disease but can transmit it to her descendants). This must be taken into account for genetic counseling.</span>

How can a change in technology affect scientific knowledge?
Shalnov [3]
It helps scientists improve on research and tests/examinations to understand the object a little more. For Example: The newer modified microscope helps zoom into harder to see microrganisms. So if technology changed then most of our scientific knowledge wouldve been mistaken this whole time. We wouldnt know many things if technology didnt exist.

A - DNA as the inheritance materials B - RNA as the inheritance materials C - The formation of organic molecules, e.g. nucleic a
Stels [109]

EXPLANATION:

There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).

Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).

The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.

Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.

A nucleotide is made up of 3 parts:

i) a nitrogenous base

ii) a five-carbon sugar

iii) at least one phosphate group.

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. ​​​​​​​ To have enough DNA
ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
