Answer:
They eliminate the native crayfish species.
Explanation:
This occurs due to their increased aggressiveness.
A. Calcium would be sent to the sarcoplasmic reticulum, causing contractions to stop. A muscle fiber ceases to contract the instant ATP is depleted. Furthermore, contraction halts when signals from the motor neuron stop, leading to the repolarization of the sarcolemma and T-tubules, thus closing the voltage-gated calcium channels in the sarcoplasmic reticulum. Calcium ions are subsequently pumped back into the sarcoplasmic reticulum, allowing tropomyosin to once again obstruct the binding sites on the actin filaments.
Not sure, maybe just look it up online, that should be effective.
Answer:
From the genotype ppccttrr, we can anticipate 16 types of gametes.
Explanation:
Gametes are haploid germ cells which can be male or female. They can fuse with opposite sex gametes during reproduction to create a zygote.
One example of a gamete is the sperm, which fertilizes the egg in reproduction. Therefore, there will be 16 distinct reproductive cells, each with a single set of unpaired chromosomes that follow the genotype ppccttrr.
