--------------------------------
Before answering the question, let us first review some theoretical frameworks,
• The tectonic plates theory explains the movement of the different plates based on the crust movements.
• The continental drift theory explains how these movements have been taking place for millions of years.
Alfred Wegener was the first one to state the concept of continental drift.
He proposed that once all continents were together a single big continent named Pangea, and with time, they split and separated into many pieces.
The geologist Du Toit published in 1937 a list of 10 pieces of evidence that would support the theory of tectonic plates and continental drift.
Du Toit's list includes evidence of Gondwana glaciation, lithological and structural evidence, plates fitting together, and paleontological evidence.
Paleontological evidence
• Plant and animal fossils distribution suggests the existence of a big unique continent. When reconstructing the supercontinent, the areas where these fossils were found get together in the same supercontinental region.
• Glossopteris (fern) impressions are widely distributed in determined areas of Africa, South America, India, Australia and Antarctica.
• Terrestrial vertebrate fossils also support the theory. The presence of Triassic tetrapods in all continents suggests terrestrial corridors between landmasses.
Finding Glossopteris in Australia, India, South America, Antarctica and Africa suggests that continents were once together, and these species used to live in the same region.
With time, these continents diverged and got separated by the oceans. The region where Glossopteris used to live got divided.

a woman has a mutation that causes the zona pellucida to be tough and not disintegrate after the egg was fertilized. how would this affect her fertility? explain.
If a woman has a mutation that causes the zona pellucida to be tough and not disintegrate after fertilization, it would likely affect her fertility by preventing successful implantation of the fertilized egg and potentially leading to infertility.
The zona pellucida is a glycoprotein-rich layer that surrounds the mammalian oocyte (egg). After fertilization, the zona pellucida plays a crucial role in facilitating the penetration of sperm and then undergoes a process called zona disintegration or zona hatching. This disintegration is necessary for the blastocyst, the early-stage embryo, to successfully implant into the uterine wall.
If a woman has a mutation that causes the zona pellucida to be tough and not disintegrate after fertilization, it can have significant implications for her fertility. The inability of the zona pellucida to disintegrate hinders the blastocyst's ability to implant into the uterine lining. This may prevent successful establishment of pregnancy and result in recurrent implantation failure or early pregnancy loss.
The tough zona pellucida can act as a physical barrier, preventing the embryo from making direct contact with the uterine lining and impairing the necessary interactions between the embryo and the endometrium. Without successful implantation, the pregnancy cannot progress.

manx cats lack tails, due to a recessive lethal allele. if a manx cat is crossed to a cat with a normal tail, what proportion of the kittens are expected to be tail-less?
Half of the kittens produced from crossing a Manx cat with a cat with a normal tail would be expected to be tail-less.
This is due to the fact that the Manx cat has a recessive lethal allele, meaning it only expresses the tail-less phenotype when two alleles for this trait are present.
When two different alleles are present, as in the case of a Manx cat crossed with a cat with a normal tail, the offspring will have one of three possible genotypes: the Manx cat's homozygous genotype (two copies of the recessive lethal allele), the cat with a normal tail's homozygous genotype (two copies of the normal allele), or a heterozygous genotype (one copy of each allele).
Since the heterozygous genotype will result in the expression of the recessive phenotype, the expected proportion of tail-less kittens from this cross would be 50%.

In vessel elements and sieve tube elements, only sieve tube elements are alive.
What are vessel elements and sieve tube elements?
Sieve-tube elements are specialized cells in angiosperms that are responsible for conducting food. A sieve-tube element's long tube-like structure is made up of cells that have no nuclei, ribosomes, or vacuoles. Vessel elements are elongated cells in flowering plants' xylem that are specialized for water transportation.
They are shorter and broader than tracheid, and they are arranged end to end. Vessel elements are often found in pairs or clusters, and they have perforations in their end walls that allow for water to flow through them. Vessel elements and sieve-tube elements are non-living cells.
In both types of cells, the nuclei and other organelles are lost as the cells mature. However, sieve tube elements are unique in that they are living cells with organelles that can continue to function throughout the plant's lifetime. So, in vessel elements and sieve tube elements, only sieve tube elements are alive.

The phenotypic difference between a person with CC genotype and one with CG is related to the ability to produce the protein erythropoietin (EPO), which is important in the production of red blood cells.
What is a phenotypic difference?The CC genotype individuals are homozygous for the wild-type allele, which results in normal EPO production, whereas CG genotype individuals carry one copy of a variant allele that affects EPO production and function.
Individuals with the CG genotype may have a reduced ability to produce EPO, which could affect their ability to produce more red blood cells at high altitudes.
This may result in a decreased oxygen-carrying capacity and a higher risk of developing altitude sickness or other related conditions. However, the exact impact of the CG variant on altitude adaptation is complex and may depend on other genetic and environmental factors as well.

The genetic makeup of an individual is called its genotype, and the physical traits of an individual are called its phenotype. Hence, option A is correct.
Similar to the term "genome," "genotype" refers to an organism's total gene pool in its cells. However, in a more restricted meaning, it can refer to various alleles, or variant versions, of a gene for specific features or qualities. The phenotype, or individual features that can be observed and are a result of interactions between the genotype and the environment, contrasts with the genotype of an organism.
Diverse settings can result in diverse phenotypes in people with a specific genotype since the phenotype is the consequence of an interaction between genes and the environment.
