Answer:
Carrying signals from the brain: The spinal cord receives signals from the brain that control movement and autonomic functions. Carrying information to the brain: The spinal cord nerves also transmit messages to the brain from the body, such as sensations of touch, pressure, and pain.
state three types of skeleton?
Answer: Hydrostatic Skeleton. A hydrostatic skeleton is a skeleton formed by a fluid-filled compartment within the body, called the coelom.
Exoskeleton. An exoskeleton is an external skeleton that consists of a hard encasement on the surface of an organism.
Endoskeleton. An endoskeleton is a skeleton that consists of hard, mineralized structures located within the soft tissue of organisms.

what type of muscle cells are arranged in sheets or layers with adjacent muscle cells electrically connected by gab junction
Answer:
smooth muscle
Explanation:
Smooth muscle fibers are spindle-shaped and, unlike skeletal muscle fibers, have a single nucleus; individual cells range in size from 30 to 200 μm. Smooth muscle fibers are often found forming sheets of tissue and function in a coordinated fashion due to the presence of gap junctions between the cells.
Which resource is a nonrenewable resource?

1. Carbon dioxide. Water • Energy - Sugar • Oxygen
2. Sugar + Oxygen - Water + Carbon Dloxide + Energy
In the second reaction shown here (cellular respiration), which of these descriptions compares the products and reactants?
Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration
What cellular process is the opposite of photosynthesis?The reverse of photosynthesis is the process of respiration. Animals like us get their energy from sugars. In cells, the mitochondria are where respiration occurs. During breathing, oxygen and sugar combine chemically to break down sugar.
Biochemical processes like photosynthesis and cellular respiration move matter and energy across the biosphere. Cellular respiration generates carbon dioxide, water, and ATP, which serve as the precursors for photosynthesis along with sunlight.
Hence, cellular respiration is reversal of photosynthesis.

What is the voltage of a galvanic cell made with magnesium (Mg) and gold
(Au)?
O A. 4.2 V
OB. 0.54 V
O C. -0.54 V
O D.-4.2 V
A. 4.2 V is the voltage of a galvanic cell made with magnesium (Mg) and gold(Au).
What is the voltage of a galvanic cell made with magnesium?The bigger the reduction ability, the more likely the steel is to be reduced and act as the oxidizing agent. Returning to the copper-magnesium galvanic cellular, the same old electrode potential of copper is 0.337 volts, whilst the standard electrode capability of magnesium is -2.370 volts.
Cell voltage is also known as cell ability (E) and electromotive force (emf). the electrical voltage or ability is measured in volts (V). The volt is related to strong values, joules (J), and electric powered fee, coulomb (C). The connection between these is defined with the equation: 1J=1C×1V.

C. a prokaryote engulfs a eukaryote
D. a eukaryote overtakes a prokaryote
Answer:
Secondary endosymbiosis is when a living cell engulfs another eukaryote cell that has already undergone primary endosymbiosis. It has happened often enough that it has led to genetic diversity among the organisms on Earth.
Explanation:
Examples are nitrogen-fixing bacteria (called rhizobia), which live in the root nodules of legumes; single-cell algae inside reef-building corals, and bacterial endosymbionts that provide essential nutrients to

A single base substitution mutation is least likely to be deleterious when the base change results in _____.
A single base substitution mutation is least likely to be deleterious when the base change results in a codon that specifies the same amino acid as the original codon.
What is the effect of single base substitution mutation?
A substitution mutation can cause the following: Change in the coding of amino acids codon to a particular stop codon resulting in an incomplete protein, which is usually non-functional. Can cause Silent mutations where a codon change can encode the same amino acid resulting in no changes in the protein synthesized.
What is base substitution mutation?Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in the place of a guanine nucleotide.

the figure shows the absorption spectrum for chlorophyll a and the action spectrum for photosynthesis. why are they different?
Absorption spectrum for chlorophyll a is different from the action spectrum for photosynthesis due to their usage.
The absorption spectrum for chlorophyll a is different from the action spectrum for photosynthesis because an absorption spectrum shows all the colors of light that is absorbed by a plant while on the other hand, an action spectrum shows all the colors of light that are used in photosynthesis.
Chlorophyll is a green pigment which absorbs all spectrum of light except the green but in the absorbed lights, red and blue spectrum participate directly in the process of photosynthesis so we can conclude that absorption spectrum for chlorophyll a is different from the action spectrum for photosynthesis.

the breaking of a large organic molecule into smaller individual subunits involves multiple ________.
The breaking of a large organic molecule into smaller individual subunits involves multiple hydrolysis reactions.
HYDROLYSIS:Hydrolysis is a type of reaction in which water is used as a reactant to break down chemical bonds of a large molecule.
As the name implies: hydro meaning water and lysis meaning break down. Larger molecules are disintegrated into two or more simpler molecules by reacting with water.
Therefore, it can be said that the breaking of a large organic molecule into smaller individual subunits involves multiple hydrolysis reactions.
