- developed from two separate eggs. Identical twins come from one zygote that splits into two embryos, while fraternal twins come from two separate eggs that are fertilized.
Answer:
AB, aB, Ab
Explanation:
Man has blood type B so could be BB (homozygous dominant) or could be Bb (heterozygous)
Woman has blood type A, so she could be AA (heterozygous dominant) or Aa (heterozygous)
Now, we need to make a separate cross for woman with AA, man with BB and we get children of all AB
Then we can make another cross for genotypes Aa and BB, and we get AB and aB
We can continue this for AA,Bb and for Aa,Bb
A microorganism (or microbe) is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled or multicellular and include bacteria, archaea, viruses and most protozoa, as well as some fungi, algae, and animals, such as rotifers and copepods. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists also classify biologically active entities such as viruses and viroids as microorganisms, but others consider these as non-living.
The right answer is 28 years.
The half-life, or period of a radioactive isotope, is the time required for half of the nuclei of this isotope initially present to decay naturally.
One gram of pure 90 strontium has a radioactivity of 5.11 TBq. Its beta radiation is not penetrating, which makes it difficult to measure when it is in the soil or a matrix. It is very harmful when the particle is inhaled or ingested.
Answer: Proteins
Explanation: A protein molecule is <u>made from a long chain of these amino acids</u>, each linked to its neighbor through a covalent peptide bond. <u>Proteins are therefore also known as polypeptides.</u>
