Answer:
Yes, they are!
Explanation:
While inhabiting marshy areas, the Balaeniceps rex is found to be both a secondary and tertiary consumer preying on fish ranging in size from that of Large Mouth Bass to the small Pacific Herring, and other aquatic organisms such as frogs similar to the Red Eyed Tree Frog
Answer:
Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.
Explanation:
Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
Answer:
Lining up of chromosomes in the cell
.
Explanation:
Prophase begins with the Thickening of chromosome. Chromosomes are clearly visible inside the nucleus. each chromosome splits longitudinally to form two chromatids.
The centriole in the centrosome of animal cell divides into two. The centrosphere set the centrioles free. Centrioles develop very fine eye-lash like thread called aster rays. the two asters start moving towards the opposite poles. By the end of prophase they reach at the opposite poles.
we can say that (F) is the dominant healthy gene and (f)is the recessive anemia gene
Falconi anemia is a recessive autosomal disease, therefore it will affect men and women equally
1)Arlene's genotype is (ff)
2)Ann's genotype is (Ff)(she's a carrier). Michael's genotype is (Ff)(also a carrier)
3)George's genotype is (Ff)
4)Sandra's genotype is, most likely (FF)
5)Sam, Ann and Michael are most likely carriers.
Here is the answer based on the given scenario above. One of the most common energy sources used by bacteria is glucose and it is such a good source of energy for bacteria because g<span>lucose is a highly reduced compound, containing many carbon-hydrogen bonds and a lot of potential energy. Hope this helps.</span>
