which part of the nervous system is responsible for relaying information from the brain to the muscles so they can walk across the room and pick something up?
Somatic nervous system is responsible for relaying information from the brain to the muscles so they can walk across the room and pick something up.
Your body's movements are initiated by and under the control of your somatic nervous system. Nearly all voluntary muscular actions are controlled by the system, which is also in charge of processing sensory data that is received from external inputs like hearing, touch, and sight. This tells us that somatic nervous system would be responsible for the movement involved in walking across the room or other.
The peripheral nervous system, which enables the brain and spinal cord to receive and transmit information to other parts of the body, includes both the somatic and autonomic nervous systems. In order to control voluntary movements and reflex arcs, the somatic nervous system connects the central nervous system to the body's muscles.

In contrast to inorganic catalysts, enzymes have an intricately shaped binding surface called the - active site.
The correct option is c.
Proteins called enzymes aid in accelerating our bodies' chemical processes, or metabolism. Some compounds are created, while others are broken down. Enzymes are a part of all living things. Enzymes are created by our bodies spontaneously.
The vital function of enzymes is to reduce the activation energy of a process, or the amount of energy required for the reaction to start. In order to facilitate the chemical bond-breaking and bond-forming processes, enzymes bind to reactant molecules and keep them in place.
Metals and their oxides supported on porous materials are examples of inorganic catalysts, also known as heterogeneous catalysts, which imitate the exquisite function of enzymes found in nature's catalysts. Through adsorption, the reactants attach to the active sites on the metal surface.

how does dna code for specific proteins within a cell
Answer:
Genetic code refers to the instructions contained in a gene that tell a cell how to make a specific protein. Each gene’s code uses the four nucleotide bases of DNA: adenine (A), cytosine (C), guanine (G) and thymine (T) — in various ways to spell out three-letter “codons” that specify which amino acid is needed at each position within a protein.

what are the advantages and disadvantages of osmosis
The benefits of osmosis to living cells is that it provides turgidity to cell tissues and the way in which cells maintain their water balance.
The disadvantage of osmosis is that it removes minerals from living cells and wastes a lot of water from cell contentWhat is meant by osmosis?Osmosis can simply be defined as the process which involves the movement of water molecules from a region of lower concentration to a region of higher concentration through a selectively permeable membrane.
That being said, one great benefit about this movement is that it gives turgidity to tissues within the cells.

what is the evolutionary benefit to meiosis in reproduction? select only one answer choice. group of answer choices meiosis produces gametes with half the required number of chromosomes that the offspring will need. meiosis produces gametes that are identical to their parent cells. meiosis produces gametes with new combinations of alleles in the chromosomes. meiosis allows for growth and plasticity in multicellular organisms
The evolutionary benefit of meiosis in reproduction is meiosis produces gametes with new combinations of alleles in the chromosomes. Therefore, the correct answer is the third option.
Meiosis is the process of chromosomal reduction that leads to the production of gametes (sex cells) needed for sexual reproduction. It only appears in eukaryotic cells that only plants, animals, and fungis have.
In this process, the double set of chromosomes is reduced into a single set. The single sets combine in sexual reproduction, resulting in double-set offspring. That allows a new combination of alleles in the new gametes while conserving the chromosomal number of the species.
