The allele that prevents the disease in the parents is a WILD TYPE allele and the one that causes the disease is a MUTANT allele. An allele is a gene variant.
Alleles and diseasesAn allele is a gene variant, in diploid organisms (like humans) two alleles are inherited for each gene locus.
A wild-type allele is an allele that produces a normal phenotype.
Conversely, a mutant allele is associated with a defective phenotype in disease and/or genetic conditions.

have existed for only 200,000 years. To put this in perspective, calculate the
percentage of Earth's history that modern humans have existed.
Human beings have existed on earth for 0.0043% of the earth history.
PercentagePercentage is used to represent a number or decimal as a fraction of 100. It is represented by the % sign.
From the question:
Percentage of Earth's history that humans have existed = (200000 years / 4.6 billion years) * 100% = 0.0043%
Human beings have existed on earth for 0.0043% of the earth history.

Question: can mendel's laws be used to predict the outcomes of genetic crosses?.
It is true that Mendel's laws can be used to predict the outcomes of genetic crosses.
What are Mendel's laws?According to a genetics principle, each sperm or egg obtains just one copy of each pair of paired hereditary units that regulate a character's expression during the creation of germ cells.
Every person has two alleles, and only one of those alleles is passed on to offspring, according to the law of segregation.
According to the law of independent assortment, inheriting one set of genes does not affect inheriting another set.
Mendel's laws make it simple to forecast how genetic crosses will turn out. However, the chance of transmission for certain gene combinations is predicted using the laws of probability.
As is well known, Punnett square can be used to quickly calculate the ratio of monohybrid and dihybrid crossings.
Thus, it can be concluded that yes, Mendel's laws can be used to predict the outcomes of genetic crosses.

In the three-domain system, the eukaryotes are represented.
Answer:
subdivides the prokaryotes into two different domains
Explanation:
The three domain system is based on differences in the ribosomal DNA of cells (16 S rRNA). In the three-domain system, Organisms are classified into three domains, namely:
Archaea
Bacteria
and Eukarya
Archaea and bacteria prokaryotes while Eukarya are the eukaryotes . Therefore, the three domain system sub-divided prokaryotees into two different domains.
Before the three-domain system, the five kingdom classification was popular, this is where plants (plantae), animals (animalia) and fungi were classified into their own Kingdoms.
List in order the blood vessels and part of the heart a glucose molecule would travel through on its way from ur digestive system to a muscle in ur leg
Answer:
Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart.
Explanation:
The correct order of blood vessels is capillaries, arteries, and veins.
What are blood vessels?The blood vessels are the thin tubes that travel blood throughout the body. Arteries. They deliver blood that is enriched in oxygen away from the heart to all the body's tissues. Capillaries. These tiny blood channels link the veins and arteries. Veins. These blood arteries transport blood from the body back to the heart.
Oxygen and nutrients from the blood enter the tissues through the capillaries' thin walls, and waste products exit the tissues back into the blood. Blood leaves the capillaries and travels through venues and veins before returning to the heart.
Therefore, the correct order of blood vessels is capillaries, arteries, and veins.

Molecule ability to diffuse across semipermeable membrane?
Answer:
Smaller molecules diffuse easily as compared to the larger molecules. In other words, smaller is the size of molecule, easier and faster is its diffusion across a semipermeable membrane.
Diffusion is a process by which molecules move ( via semipermeable membrane) from an area where its concentration is higher to an area where its concentration is lower.
Size of molecules can impact the process of diffusion as smaller is the size, faster is the rate of diffusion.
