In contrast to the sympathetic nervous system, the parasympathetic nervous system:_____.
In contrast to the sympathetic nervous system, the parasympathetic nervous system controls the functions when an individual is at rest.
Sympathetic nervous system controls the body's fight or fright response. This means it is functional when the body undergoes some stress, danger or excitement. The hormones associated with it are epinephrine and nor-epinephrine.
Parasympathetic nervous system controls all the activities that relax the body. These functions include digestion, breathing, lacrimation, etc. The chemical released during this response is acetylcholine. Acetylcholine can bind to two types of receptors: nicotinic receptors and muscarinic cholinergic receptors.

how many kinds of waves are there?
Answer:
There are two main waves; transverse and longitudinal. Transverse waves are like the waves we see in the ocean when we are at the beach. Longitudinal waves consist of sound, but different. Longitudinal waves have more complex properties than sound waves. They follow a consistent pattern of compressions and rarefactions within a(consistent) medium.
In-case you wonder what a medium is, a medium is the substance that carries the wave. Remember that it only transports the wave, and it plays no part in actually making the wave. When waves crash, the particles within the medium are disturbed, so they carry/pass on the disturbance to keep the wave's pattern consistent.

Plant cells, unlike animal cells, are characterized by the presence of a ______. select all that apply.
Plant cells, unlike animal cells, are characterized by the presence of a cell wall.
Cell walls are a protective layer that is rigid and only partially permeable on some types of cells. This outer layer is located near the cell membrane in the majority of plant cells as well as those of fungi, bacteria, algae, and some archaea (plasma membrane).
Animal cells, however, do not have a cell wall. The cell wall of a cell performs a number of essential functions, including support, construction, and defence.
Depending on the organism, the cell wall's makeup varies. The vast majority of a plant's cell wall is made up of sturdy cellulose fibres. Cellulose, a substance used in the production of paper, is found in large quantities in both wood and cotton fibre. The walls of bacterial cells are composed of a polymer of sugar and amino acids called peptididoglycan.

Option D: The cells in the nervous system that handle information processing are called neurons.
Nerve cells, often called neurons, are the building blocks of the nervous system. They interact with the information and transfer this information along various distances through electrical impulses. The nervous system is generally made up of two types of cells: nerve cells and glial cells. Glial cells are the supporting system of neurons. The nervous system is broadly divided into two categories:
The central nervous system (CNS) contains the brain and spinal cord
The peripheral nervous system (PNS) contains neurons and their parts such as sensory neurons and motor neurons.
Analysis of the information brought in by sensory neurons is done in CNS while PNS works as transportation for these signals from one neuron to another. Motor neurons carry the signals out of the CNS after analysis.
Information processing in the nervous system is handled by neurons or their parts like interneurons that connect one neuron to another in the CNS. These signals are then transferred by motor neurons to respond to stimuli.

During transcription, rna polymerase synthesizes ______ from a(n) ______ template.
During transcription, rna polymerase synthesizes RNA strand from a(n) DNA template.
What is transcription?Transcription is a classic event in molecular biology in which the DNA is transcribed to mRNA.
Transcription is an important event mentioned in central dogma of molecular biology. It is from transcription, translation (synthesis) of proteins is possible.
Transcription occurs at specific site in the cell. In prokaryotes, transcription takes place in cytoplasm whereas in eukaryotes, nucleus is the site for transcription.
Transcription involves three main steps:
Initiation - Binding of an enzyme RNA polymerase at the promoter region initiates the process of transcription. Thus, an mRNA strand is produced from a DNA sequence.Elongation - Specific nucleotides are added to this mRNA strand through complementary base pairing (A-U, C-G).Termination - RNA polymerase comes across a termination sequence in a gene and stops the process.After transcription, processing of mRNA is carried out so that it becomes mature and fully functional for translation process.
Therefore, transcription is important in copying information from DNA sequences for the correct synthesis of proteins.

Transport proteins (transporters) require energy expenditure for each molecule of substrate transported. the reason for this energy requirement is option(a) i.e, the solute must be transported against a concentration gradient.
Transport proteins are integral transmembrane proteins, which means they span the membrane across which they transport things and remain there permanently. Through enhanced diffusion or active transport, the proteins may aid the movement of molecules. Transport proteins that participate in assisted diffusion include channel proteins, gated channel proteins, and carrier proteins.
Transport proteins enable everything from nerve impulses to cellular metabolism by transferring molecules across membranes. For instance, the sodium-potassium gradient that causes our nerves to fire would not exist without transport proteins.

How does the structure of the plasma membrane depend on the amphiphilic (means both hydrophobic and hydrophilic) nature of phospholipids?
The amphiphilic molecules arrange themselves into a bilayer, with their hydrophilic phosphate-containing heads facing the water on each side of the membrane and their hydrophobic tails directed towards the center, avoiding water.
A phospholipid is a lipid composed of two fatty acid tails, glycerol and a phosphate-linked head group. Biological membranes typically have two phospholipid layers with their tails pointing inward, a configuration known as a phospholipid bilayer.
The primary material of the plasma membrane is composed of phospholipids arranged in a bilayer. They are amphipathic, which means they have both hydrophobic and hydrophilic regions, making them ideal for this role.

The transfer of traits from one generation to the next is known as heredity, also known as inheritance or biological inheritance. Whether through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic make-up of their parents. Variations between people can accumulate through genetics and lead to the natural selection-driven evolution of species. Genetics is the study of heredity in biology. It is well acknowledged that DNA, a molecule that conveys genetic information, is a significant carrier of heritable traits. DNA is a lengthy polymer that contains four types of interchangeable bases.
