The diagram shows a pedigree for a recessive inherited trait. If H represents the dominant allele and h represents the recessive allele what are the genptypes of the parents shown in the pedigree.

Answers

Answer:

Hh

Explanation:

if you have a dominant allele and a recessive allele they'd be different (heterozygous)

If H represents the dominant allele and h represents the recessive allele, Hh is the genotypes of the parents shown in the pedigree.

What is genotypes?

The type of variation present at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolize it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.

The actual DNA sequence, such as CC, CT, or TT, can also serve as a representation of a genotype. In a single experiment, the genotypes spanning millions of sites in a genome can be determined using DNA sequencing as well as other techniques. If H represents the dominant allele and h represents the recessive allele, Hh is the  genotypes of the parents shown in the pedigree.

Therefore,  Hh is the  genotypes of the parents shown in the pedigree.

What does these mean (thermal energy, convection, radiation and coundution)

Answers

Answer:

Thermal Energy: It refers to some distinct physical concepts, such as the internal energy of a system or heat or sensible heat. And these mode of transfer of heat include, convection, conduction and radiation which I have explained below.

Convection: This is a mode of transfer of heat in which bulk movement of molecules within fluids takes place, as these molecules move the heat obtained by each of the molecules will reach the new location.

Radiation: Radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium

Conduction: Conduction is the transfer of internal energy by microscopic collisions of particles and the movement of electrons within an object.

Diamonds have a density of 3.26 g/mL. What would be the mass of a diamond with a volume

density = mass/volume

It follows that mass = density times volume. Thus, the given the density of diamonds being 3.26 g/mL and a volume of a diamond being 0.350 mL, the mass of this diamond would be (3.26 g/mL)(0.350 mL) = 1.14 g.

A pebble is dropped into a cup of water and sinks to the bottom ofthe cup. A solid metal bead of exactly the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare?

Answers

Answer:

A solid metal bead of the same size is dropped into the same cup and sinks to the bottom of the cup. How do the pebble and the metal bead compare? They both have the same mass. They are both denser than water.

Explanation:

nun

Answer:

Both the pebble and metal bead of the same mass will be equally accelerated  if they are at the same place, in this case, they are in the same place meaning they will be accelerated at the same speed towards the earth. Thus even if they are in the water they will sink at the same speed and finally will reach the bottom of the cup.
