Nerve cells release neurotransmitters across gaps and secretion of proteins and wastes: it’s Exocytosis
The answers are A) ectoderm and B) endoderm.
Fertilization is a fusion of male and female gametes which leads to the formation of a zygote. The zygote undergoes mitosis and transforms into a single-layered blastula. Gastrulation is a transformation of the blastula into a two-layer or three-layer gastrula. Cnidarians are a diploblastic animal because their gastrula has only two layers - endoderm and ectoderm.
Answer:Oxygen
Explanation: During cellular respiration, glucose is broken down in the presence of oxygen to form carbon dioxide, water and energy. Glucose + oxygen --> carbon dioxide + water + energy.
The balanced chemical equation for cellular respiration is C6H12O2 + 6O2 --> 6CO2+ 6H2O + Energy
Answer:Margulis
She is the one who discovered it
<u>Evolution is sometimes a controversial:</u>
Evolution is the most scientific explanation about how the life forms of earth originated and turned into the form that we see today.
I don’t think there should be a controversy because there is no other explanation that proves to be more logical than the theory of evolution. Evolution is a theory that has several supporting proofs and the theory itself was formed after several years of detailed study and observation.
I don’t think alternatives to evolution should be taught at schools. Alternative theories to evolution are based on various religious beliefs which lack a scientific basis.
Schools should be a place that enables students to do productive scientific thinking and teaching alternatives to evolution wouldn’t be a good idea.
