Answer:
Prokaryotic cells have entirely different structures for organizing their DNA, the prokaryotic chromosome equivalent is called a genophore and is localized within the nucleoid region... The structure of chromatin networks is currently poorly understood and remains an active area of research in molecular biology.
Explanation:
A potometer can be used to measure the rate of transpiration that's proportional to water uptake. Transpiration cannot be measured directly as some of the water will be used in photosynthesis.
C no because many species went extinct without leaving fossils behind
Trisomy is the answer.
A trisomy is a chromosome abnormality in which a person has three copies of a particular chromosome rather than the expected two.
Trisomies can have varying effects on a person's health depending on which chromosome is affected by the trisomy. Some trisomies such as trisomy x have only mild effects whereas others such as trisomy 21 also known as Down syndrome result in health problems and development delays.
Many Trisomies can have fatal consequences such as trisomy 16 or trisomy 18 .They frequently cause miscarriages or loss of the baby shortly after birth.
Answer:
One copy comes from each parent
Explanation:
The correct answer would be that <u>one copy comes from each parent</u>.
<em>During gamete formation, the chromosome number in the sex cells is usually halved to produce haploid gametes. Haploid gametes fuse together and donate their chromosomes to form a diploid zygote during the fertilization process. Hence, one copy of the two chromosomes in diploid organisms comes from each parent.</em>
