Answer:
sexual
Explanation:
a gamete is a mature haploid cell that can form a zygote if it joins with a gamete of the opposite sex.
Answer:
What would explain the change in reaction rate —degradation of cellulose by the enzyme cellulase—after 75 minutes is the depletion of the substrate on which the enzyme must act.
Explanation:
A chemical enzymatic reaction, such as cellulase degradation of cellulose, occurs until the substrate is consumed.
The solution to which cellulase is added has the same concentration of cellulose, and what is done is to add enzyme. In the graph you can see that the reaction takes place over time, decreasing the amount of glucose obtained. From 75 minutes onwards the reaction rate decreases as well as the amount of glucose obtained from the reaction, which is due to the fact that the substrate —cellulose— is being depleted.
<u>Answer</u>: d. it will release chemical messengers.
The action potential, which is an electric pulse, will travel down the axon untill it reaches the synapses. At the synapses, neurotransmitters (chemical messengers) will be released by the neuron.
it is considered feedback mechanisms because the menstrual cycle only happens when the hormone is released, it causes the target tissues to react, that reaction is the feedback.
The 30 million years ago, because its the closest one to us. Wait is there a picture to it ?
