Answer:
Secretion of the neurotransmitter serotonin, which is a water-soluble amine molecule
Explanation:
Exocytosis is defined as the process where cell transports secretary products which are packaged in transport vesicles such as antibodies, peptide hormones, secretory proteins, and enzymes with the help of cytoplasm to the plasma membrane.
Some example of exocytosis are:
1) Neurotransmitters secrets from nerve cells.
2) Antigens which helps to stimulate the immune response.
3) Proteins of the plasma membrane.
Answer:
deoxyribonucleic acid in short DNA
It is a double helix
It is a molecule that contains the instructions an organism needs to develop, live and reproduce.
<em><u>translation in dna</u></em>
DNA translation is the term used to describe the process of protein synthesis by ribosomes in the cytoplasm or endoplasmic reticulum. ... tRNAs carry particular amino acids, which are linked together by the ribosome. In this process, the mRNA is decoded to produce a specific amino acid chain, known as a polypeptide.
Answer:
b) Reptiles, birds, and some mammals produce amniote eggs.
Explanation:
All the mammals produce amniotic eggs. An amniotic egg is an egg that has four extraembryonic membranes including amnion. Amnion is a fluid-filled sac that serves as a cushion and does not allow the egg to desiccate. Since mammals are land animals, they have amniotic eggs to prevent any damage to the embryo from desiccation and physical injury.
Not very many, as most would get mauled and eaten by bears and other predators
Answer:
The correct answer is - Polymers are macromolecules
Explanation:
Macromolecules are termed as macro and molecules mean huge atoms, for instance, proteins. It is made by the polymerization of monomers. Macromolecules are being made out of numerous atoms.
The usually utilized atoms in natural chemistry are lipids, carbohydrates, nucleic acid, and proteins, all are made of their respective monomers that are fatty acids, monosaccharides, nucleotides, and amino acids.
Thus, the correct answer is - Polymers are macromolecules
