Answer:
Two alleles is correct
Explanation:
Alleles are versions of the same gene with slight variations in their sequence of DNA bases. These small differences among alleles of the same gene contribute to each person's unique characteristics.
The first fossils of animals with hard parts appeared about 541 million years ago. What percentage of geologic time does the fossil record represent
The percentage of geologic time does the fossil record represent 20%.
What are Fossils and Fossil records?Fossils refers to remnants or traces once-living thing from the past. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood, oil, coal, and DNA remnants.
Fossil record is the compilation of all known and unknown fossils over a period of time.
The importance of fossil records includes:
1) Fossil records give scientists clues as to what the Earth was like millions of years ago.
2) Fossil records are used to determine how organisms alive today evolved.
3) It helps to understand how life in has changed over time.
Thus, percentage of geologic time does the fossil record represent 20%.

The lateral kidney position allows approach to the retroperitoneal area of the flank. to render the kidney region readily accessible, the ______ is raised, and the bed flexed so that the area between the twelfth rib and the iliac crest is elevated. compression of the _______ can occur when the flank is raised too high.
Filling in the blanks
The lateral kidney position allows approach to the retroperitoneal area of the flank. to render the kidney region readily accessible, the kidney bridge is raised, and the bed flexed so that the area between the twelfth rib and the iliac crest is elevated. compression of the vena cava can occur when the flank is raised too high.
Kidney bridge vs Vena CavaThe kidney bridge is used during gallbladder and kidney operations to enable the proper positioning of the patient on he operating table usually Obese patients, it renders the kidney region readily accessible. While Vena cava transports blood through the major organs in the body and it's compression can occur when the flank is raised too high.
Hence we can conclude that The kidney bridge is used during gallbladder and kidney operations to enable the proper positioning of the patient on he operating table usually Obese patients, it renders the kidney region readily accessible.

For example, when the asteroid wiped out all the dinosaurs that was a mass extinction, but the gradual disappearance of the African Black Rhino would simply be considered as an extinct species because of the fact that not every kind of Rhino to ever exist was wiped out.
what is the probability that a gamete will be recessive in a heterozygous parent
A heter0zygous parent (Aa) has one dominant allele (A) and one recessive allele (a). They will produce 4 gametes and half of their alleles are recessive so there is 50% that a given gamete will be recessive (2 gametes have recessive, 2 gametes have dominant)
What is an allele?Assuming the gene is represented by the allele G (dominant), the alternate form (recessive) of the allele will be g.
A heter0zygous pea plant will have the genotype Gg. During gamete formation, Gg will split into G and g gametes.
Thus, 2 is the probability that a gamete will be recessive in a heterozygous parent.

olfactory cells and taste buds are normally stimulated by ________.
Answer:
The answer is substances in solution.
Explanation:
Olfactory cells and taste buds are normally stimulated by substances in solution.
Olfactory cells are normally stimulated by odorants, which are chemical substances that are volatile and capable of being detected by the sense of smell.
Taste buds, on the other hand, are normally stimulated by tastants, which are chemical compounds that can be tasted. Tastants include various molecules such as sweet, sour, bitter, salty, and umami compounds.
Both olfactory cells and taste buds play crucial roles in our perception of smell and taste, respectively, and they are stimulated by specific chemical substances that interact with receptors present in these sensory cells
