A: an ecosystems organisms become larger as succession
<h3><u>Answer;</u></h3>
Gap junctions
<h3><u>Explanation;</u></h3>
- Gap junctions allow the exchange of ions, second messengers, and small metabolites between adjacent cells and are formed by two unrelated protein families, the pannexins and connexins.
- <em><u>Action potentials generated by the autorhythmic cells spread waves of depolarization to contractile cells through gap junctions. If the depolarization causes the contractile cells to reach threshold, they will in turn generate an action potential.</u></em>
Answer: The same amount of bacteria is dependent variable
Two types of variables are used to do an experiment, independent variable and dependent variable. The variable which is used to test the effect on dependent variable is called an independent variable and the variable which is being tested and measured is called a dependent variable. In the given experiment, the same amount of bacteria is dependent variable, which is being tested and measured. The different temperature is independent variable.
The zygote is split into the blastula after fertilization. The three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.
Fertilization :
The majority of animal reproduction is comparable to human reproduction. Additionally, animals create gametes for fusion. Gamete fusion, however, can happen inside or outside of the body.
Type of fertilization :
internal and external fertilization.
How does fertilization work, for insinstance ?
A reproductive technique that involved joining a male and a female germ cell—each with a single, haploid pair of chromosomes—to produce a diploid cell known as a zygote.
Pre-embryo is a collection of blastomeres formed by cleavage divisions.
