Answer:
If the paired chromosomes fail to separate during meiosis in the female, then the resulting daughter cells will receive either 2 or no copies of chromosome 21. If the resulting egg with 2 copies of chromosome 21 is fertilized with a normal sperm, the resulting zygote with be trisomy 21
Explanation:
Answer:
ATP is used for many cell functions including <u><em>moving substances across cell membranes</em></u>, <u><em>supplying the energy needed for muscle contraction</em></u>, <u><em>supplying the needed energy to synthesize the multi-thousands of types of macromolecules</em></u> that the cell needs to exist. It supplies energy not only to heart muscle (for blood circulation) and skeletal muscle (such as for gross body movement), but also to the chromosomes and flagella to enable them to carry out their many functions. ATP is <em><u>also used as an on-off switch both to control chemical reactions and to send messages.</u></em>
Answer:
The correct statements for amino acids but not for sugars are :
C. typically contain nitrogen
E can bond together to form proteins
Explanation:
Both Sugars and amino acids always contain carbon molecules and both macromolecules can provide energy so are the source of the energy. Sugar molecule more specifically glucose molecule enters glycolysis during the cellular respiration process.
Amino acids always contain the nitrogen molecule in the structure along with carbon, oxygen, and hydrogen, there is a side chain present. Amino acids are the building blocks of the protein, peptide bonds are formed by amino acids together to make a poly peptide chain of a protein molecule.
Answer:
Eukaryotic plant cell
Explanation:
Eukaryotic cells have a defined nucleus, unlike prokaryotic cells. Plant cells also have chloroplasts, unlike animal cells and prokaryotic cells, because prokaryotic cells do not contain any membrane-bound organelles (e.g. nucleus, chloroplasts, mitochondria etc.)
