The reason people who have AIDS can't fight it off is because it is an immune disease it quickly weakens the immune system and makes a persons body too weak to fight anything off.
A punnet square predict the traits of offspring genetic crosses and test crosses.
<u>Explanation:</u>
In pea plants, the traits or characteristics inheritance is been observed and studies by Gregor Mendel. A model was proposed by him, in which the characteristics or traits are specified from genes. Genes can take different alleles or versions. The appearance of an organism can be determined by the dominant alleles. These hides the characteristics of recessive alleles.
The law of segregation is, When gametes are made by an organism the copy of one gene is passed to each gametes. The combinations of allele which is genotype, and the phenotypes which are the characteristics that are observable can be predicted by a Punnett square. This is done by genetic crosses.
In order to predict whether the organism is heterozygous or homozygous can be determined by a test crosses.
Answer:
Cellular Respiration
Explanation:
In cellular respiration, animals take in O2 (oxygen) and exhale CO2 (carbon dioxide).
The rotation of the Earth in its axis
I believe the answer for this would be B. Just using the process of elimination knocks out D and A, and plants make carbs not protein during photosynthesis :)
