The fact that it turns from liquid to vapor, means you're dealing with the boiling point of the substance. If its temperature doesn't vary during the turning of phase, it means the substance is pure. In this case, since it becomes liquid at 100ºC , it might probably be water.
I hope this helps :)
Answer: Chloroplast
Explanation:
Plants use photosynthesis to make energy for themselves and this process is located in the chloroplast. If you can't remember this, you might remember the name chlorophyll which is the food a plant makes. The prefix is similar as you can see.
Answer:
There is no punnet square attached but generally none of the offsprings from this cross will be homozygous dominant. The answer is 0.
Explanation:
The question illustrates a single trait encoded by a single gene. According to Mendel, a gene comes in two alternative forms called ALLELES. Each allele encodes different characters of the same gene. For example, let's use the trait for height encoded by a certain gene that has alleles T for tallness and t for shortness. T is dominant over t, meaning that T (tallness) will always mask the phenotypic expression of t (shortness) in a heterozygous state.
A heterozygous parent contains different alleles of the same gene i.e. Tt in this case. However, due to the dominance of allele T (tallness) over allele t (shortness), the tall trait will be expressed. On the other hand, a homozygous recessive parent contains the same alleles for the recessive trait i.e. tt
Using a punnet square, a cross between a heterozygous (Tt) parent and a homozygous recessive parent (tt) will produce offsprings with genotypes: Tt and tt in a 1:1 proportion.
Tt is heterozygous dominant
tt is homozygous recessive
None of the offsprings are homozygous dominant (TT), hence, the probability of producing a homozygous dominant offspring is 0.
t t
T Tt Tt
t tt tt
Is there a question i’m supposed to answer or is it just completely free?
