When an action potential reaches presynaptic terminal on a neuron, it will induce a release of neurotransmitters from the neuron. Neurotransmitters pass through the synaptic cleft and bind to the receptor on a postsynaptic neuron.
The protons and neutrons are much more massive than the electrons.
Electrons have a negative charge.
Electrons are located outside the nucleus.
Answer:
The correct answer is d = Electrons are outside the nucleus.
Explanation:
Hello ! Let's solve this!
The mass of the atom is measured as the number of protons and neutrons in the nucleus of an atom.
Since electrons are outside the nucleus, they are not counted to know the mass.
The correct answer is d = Electrons are outside the nucleus.

C : Diabetes

DNA is a molecule that controls cellular activity by directing the synthesis of proteins.
The nucleus contains the cell's DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.
Thus, DNA is a molecule that controls cellular activity by directing the synthesis of proteins.

B. Both are multicellular and haploid, are often found in fossil remains, and have cell walls made of cellulose.
C. Both have cell walls made of cellulose, have xanthophyll as their chief photosynthetic pigment, and are multicellular.
Answer:
The correct answer is statement A.
Explanation:
Green algae belong to the division Chlorophyta and comprise about 9000 to 12000 species. Like higher plants, green algae possess photosynthetic pigments like carotene, chlorophyll a and b, and xanthophyll, in a similar proportion as found in higher plants.
A cell of green algae can be sessile or motile, and exhibits a central vacuole, and possesses a two-layered cell wall formed of cellulose and pectin. The storage of food takes place in the form of starch in the pyrenoids. Thus, due to the similarities in the features between the plants and green algae, it is considered that the embryophytes or the lands plants have emerged from green algae. Hence, statement A supports the belief.
Most scientists believe that green algae are the ancestors of plants due to their similar biochemical features. These include having cell walls made of cellulose, the storage of food material as starch, and the presence of chlorophyll a and chlorophyll b.
According to most scientists, the belief that green algae are the ancestors of plants is best supported by the statement: Both have cell walls made of cellulose, store food material as starch, and have chlorophyll a and chlorophyll b. These characteristics highlight the similar biochemical features that underline the evolutionary relationship between green algae and plants. The presence of cell walls made of cellulose provides structural similarities. Storage of food material as starch indicates similar metabolic processes, and both having chlorophyll a and chlorophyll b reveals their shared capacity for photosynthesis, a defining feature of plants.

B: dehydration synthesis; hydrolysis
C: is crossed off
D: hydrolysis; glycolysis
The right option is B: dehydration synthesis; hydrolysis
The process of linking monosaccharides to become polysaccharides is called dehydration synthesis, while breaking down polysaccharides, like glycogen, occurs during a process called hydrolysis.
Dehydration synthesis is the process of linking two smaller molecules, or compounds, together to form a larger molecule following the loss of a water molecule.
Hydrolysis is the process of using water to break down a molecule such as carbohydrate into its component sugar molecules.
