Answer:
Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell through the various checkpoints. Cyclins regulate the cell cycle only when they are tightly bound to Cdks.
Explanation:
Answer:
Ribosomes are produced by the nucleus. Specifically, the nucleolus.
Explanation:
Flamingos are born white, but they turn pink because of the food they eat; this is an example of how
environment, a physical factor, can affect phenotypes.
<span>The phenotype is the visible physical or biochemical characteristic of an individual organism which is determined by both genetic factors (genotype) and environmental influences. There are many e</span><span>nvironmental factors and they include diet, climate, illness and stress. If environmental factors have a strong influence this means the phenotypic plasticity is high (capable to change).</span>
Answer:
1 Tg: 1 tg
Explanation:
The plant named George is heterozygous for height (Tt) and homozygous for yellow pods (gg). Therefore, its genotype is Ttgg. The two alleles for the height (T and t) would segregate from each other and will be distributed to different gametes. The presence of similar gametes for pod color (only "g") would make this plant to make all the gametes having "g" allele. Therefore, 50% gametes from this plant would have one copy of T and one copy of the g allele while the rest 50% would have one copy of "t" and one copy of the "g" allele.
Gametes produced by George= 1 Tg: 1 tg
