Answer:

The photobiont supplies the association organic carbon from photosynthesis, and the mycobiont ensures protection and regulates the supply of minerals and water. The nutritional exchange between partners is probably much more complex than exchange of water and minerals for organic carbon. Thus, the correct answer is option B.

Answer:

A. Homologue.

B. Chiasma.

C. Synaptonemal.

D. Synaptonemal.

E. Synapsis.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Matching the various terminologies in genetics with their description, we have;

A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.

C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.

D. Synaptonemal: four chromatids are held together by a zipper-like structure.

E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

Explanation:

Vitamin D controls your skin pigment. It's kind of like when someone has an iron deficiency they get bruises and they turn a whiter shade.

Hope I helped :)

The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.

 Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.

Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.

Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.

pericardium

Explanation:

A double-walled membrane, the pericardium, separates the right and left chambers, preventing oxygen-rich blood from mixing up with the one without oxygen. So, the heart functions go smoothly. Deoxygenated blood enters the right atrium.

Answer:

AZT inhibits reverse transcriptase enzyme.

Explanation:

AZT inhibits reverse transcriptase enzyme that is used by the virus to make a DNA copy of its RNA. This Azidothymidine prevent reverse transcriptase enzyme from doing its function properly. Due to absence of this enzyme, the HIV virus is unable to make copies of its DNA and this Azidothymidine stops the life cycle of the virus and slows the growth of AIDS disease so that's why this drug was considered effective against HIV virus and used in the treatment of AIDS disease.

Answer:

Humans drinking raw date palm sap was the cause of the Nipah virus outbreak in Bangladesh. Scientists found Nipah virus in bat excretions and discovered that bats were contaminating date palm juice with their excretions (saliva, urine).

Explanation:

Nipah virus can spread to people from:

1) Direct contact with infected animals, such as bats or pigs, or their body fluids (such as blood, urine or saliva).

2) Consuming food products that have been contaminated by body fluids of infected animals (such as palm sap or fruit contaminated by an infected bat).

Answer:

1. The central dogma of molecular biology is DNA >>transcription>> RNA >>translation>> protein

2.  DNA replication refers to the genetic process of generating two identical DNA molecules from one DNA sequence. Recombination refers to the exchange of genetic material (DNA) between non-sister chromatids during cell division (meiosis)

Explanation:

Gene expression (also known as transcription) is the process by which a specific fragment of DNA called gene is used as template to synthesize an RNA molecule, usually a messenger RNA (mRNA), which is in turn used as template to create a protein. This final product (i.e., the protein) has an effect on the phenotype of the individual. The DNA template is a single-stranded ordered polynucleotide chain composed of four different types of nitrogenous bases: Adenine, Thymine, Guanine and Cytosine. In the complementary RNA molecule, Thymine bases are replaced by Uracil bases. Moreover, DNA replication refers to the process by which cells duplicate their genetic material before cell division (either mitosis or meiosis). During this process, both DNA strands are separated and each one is used as a template to synthesize a new DNA molecule. Finally, recombination or crossing over is a process where non-sister chromatids exchange genetic material during meiosis I (Prophase I). Recombination is known to increase genetic variation in resulting meiotic cells.

DDDDDDDDDDDDDDDDDDDDDDDDDD

Answer:

The answer is C.

Explanation:

This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.

The study of a living being is called biology.

The correct answer is B.

The characters in the plant are controlled by the genes which are present on the chromosome. The genes are always present in pairs and a single gene is known as an allele. The alleles are as follows:-

According to the question, most of the offspring are tall in height due to the dominant allele while the number of the dwarf plant is less as this character is shown by the recessive genes.

The dominant plant suppresses the character of a recessive gene and hence the number of the dominant plant is always more.

Hence, the correct answer is B. Dwarf stem length is a recessive trait.
