The allele for dwarfism - D its dominant
Recessive allele -d
If the person has heterozygous alleles -Dd the person will have achrondroplastic dwarfism
However if the person if homozygous for the allele DD it’s Lethal and person can’t survive
If both parents are Dd
Dd X. Dd
Offspring DD Dd Dd dd
Probability of children who survive with the trait have the genotype Dd
Probability - 1/4 + 1/4
Probability of having surviving children with the trait -1/2 -0.5
True, there are many vessels serving as a conduit<span> between the lungs and the heart.
The number of the vessel is many because all the carbon dioxide from body need to be released at the lungs. More vessel means more surface area and blood flow rate to do the diffusion of the gas which means increased diffusion rate. This will allow the lung to transfer oxygen and dump carbon dioxide faster.</span>
<span>Actually energy is the capacity to do work. It is not moving. It is transmitted, propagated, dissippated, or radiated. It depends upon what type of energy it is. Heat energy is dissippated through conduction, convection or radiation. For conduction the particles must be in contact. For convection the particles which posses the energy must ba able to move about. For radiation, even without a material medium the energy is transmitted in the form of waves. Eg. energy from the sun. When a stone is dropped in still water the energy is imparted to the water surface. This energy is distributed all over the water surface in the form of circular waves (ripples). Electrical energy - through conducting wires or electromagnetic radiation. Light energy & sound energy are through waves.</span>
Answer:
I believe that the protists were the first organisms on earth. And the other 5 kingdoms then came from the protists.
I think that's it! :)
