Answer:During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. ... During interphase, the cell grows and the nuclear DNA is duplicated. Interphase is followed by the mitotic phase.
Explanation:
Producers get most of their energy from the sun as they are autotrophic, meaning that they contain chlorophyll which they use to make their food through photosynthesis.
Answer:
A threshold level depolarization.
Explanation:
In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.
A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.
Answer:
There's 25% probability that their next child will be normal, and 75% of it being a dwarf.
Explanation:
Achondroplasia (A) is a dominant trait.
Two achondroplastic dwarfs (A_ x A_) have a dwarf child (A_) and a normal child (aa). The second child must be aa because if it had a dominant allele it would also be dwarf.
The only way for two achondroplastic parents to have a normal child is that <u>they are both heterozygous (Aa) for this gene.</u>
The cross Aa x Aa would produce the following offspring probabilities:
- 1/4 AA - dwarf
- 2/4 Aa - dwarf
- 1/4 aa - normal
So there's 1/4=25% probability that their next child will be normal, and 3/4=75% of it being a dwarf.
