Explanation:
Nuclear fusion is a process in which two small nuclei combine together to result in the formation of a larger nuclei.
In Sun, the first step of hydrogen fusion includes combining of two hydrogen nuclei to result in the formation of a deuterium, positron and neutrino.
The nuclear fusion reaction inside the sun is as follows.

Thus, we can conclude that products of step 1 of the hydrogen fusion process in the Sun are isotope of hydrogen, a neutrino, and a positron.
Based on the description above, the molecular clock data
shows is that the Clams and Snails are more similar and related in structure
compared of the clams and squids. It is because it could be seen in the process
that organism are better in adapting to their environment in means of
increasing their number, survive and to pass on their traits to the next
generation.
Answer:
Explanation:
The uterus is a hallow and flattened muscular organ that is the home to developing fetus.It is divide into three parts:fundus, body, and cervix.
Its functions are:
1.to regulate menstural cycle throughout the reproductive period.
2.to pass the sperms towards fallopian tubes for fertilization.
3.to provide site for embedding zygote.
4.to expel fetus through cervix at the time of birth.
Answer:
In insects such as cockroach, grasshopper
Explanation:
Insects such as grasshopper has open circulatory, in them the body fluid is the hemolymph. The hemolymph does contain any respiratory pigment. It bathes the organs directly as it is pumped between open spaces in the body.
Thus, in insects, the blood and the interstitial fluid considered to be the same body fluid?
