Interneuronal communication occurs via _______________ messengers that are released from the presynaptic neuron. These are called _____________ and they act by binding to receptors on the postsynaptic neuron. This binding opens ____________ channels, which can either hyperpolarize or depolarize the postsynaptic neuron membrane. This action is kept relatively short by either the decomposition or the ______________ of neurotransmitters from the synaptic cleft.
Answer:
Interneuronal communication occurs via chemical messengers that are released from the presynaptic neuron. These are called neurotransmitters and they act by binding to receptors on the postsynaptic neuron. This binding opens Ion channels, which can either hyperpolarize or depolarize the postsynaptic neuron membrane. This action is kept relatively short by either the decomposition or the reuptake of neurotransmitters from the synaptic cleft.
Explanation:
Neurons are communicated to each other by a process known as synapsis. Synapsis occurs when the presynaptic neuron sends a message to the postsynaptic neuron. Vesicles from the presynaptic membranes are sent carrying the chemical messenger in their interior. This messenger is called a neurotransmitter and is released by exocytose to the synaptic space. Then the neurotransmitter goes forward to the postsynaptic membrane. When it reaches this last membrane, the neurotransmitter binds its receptor triggering an answer and opening ion channels. This binding produces depolarization of the cell called excitatory postsynaptic potential. If the signal molecule keeps being in the synaptic space, it keeps linking to its receptor and causing a postsynaptic answer. To stop this process, the neurotransmitter must be taken out from the synaptic space by enzymatic degradation/deactivation or Reuptake. There are receptors located in the presynaptic membrane that can capture de molecule to store it back in new vesicles, for posterior use.

Vertebrate animals are organisms that have a spinal column and use bones to support their weight. Scientists consider bones to be an organ of the skeletal system. What organ of a plant is most similar to a bone in animals.
A. Stem
B. Root system
C. Cell wall
D. Phloem
Answer: The stem, the stem keeps the plant stable. Much like our skeletal system.
The stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.
What is vertebrate?Vertebrate is defined as any terrestrial animal, which is the most prevalent subphylum of the phylum Chordata. Vertebrate animals are those that have a backbone. There are many vertebrates on the planet today, and they are divided into 7 classes according to their physiological and anatomical characteristics.
Stem cells are defined as unique human cells that can differentiate into a wide range of cell types, from brain cells to muscle cells. Stem cells can differentiate in the body into a wide range of various cell types. They act as the body's system for repairs. Adult stem cells and embryonic stem cells are the two primary categories of stem cells.
Thus, the stem cells of the organ of a plant is most similar to a bone in animals. Hence option A is correct.

what are the parts of the digestive system and their functions?
Mouth - break down food mechanically and chemically
Salivary Glands - produce saliva that contains enzymes which chemically break down food
Esophagus - move food from mouth to stomach through a process called peristalsis
Stomach - chemically break down food with stomach acid, mechanically break down food with the contracting of stomach muscles
Liver - creates bile that helps with digestion, stores, distributes and breaks down nutrients
Gallbladder - temporarily stores bile and squeezes it into the small intestine to break down fat droplets
Pancreas - produces pancreatic juice that contains digestive enzymes and bicarbonate
Small Intestine - absorbs nutrients from chyme
Large Intestine - absorbs water and dries out food, turning it into waste
Rectum - stores waste before it leaves the body
Anus - an opening where waste exits the body

How are land plants adapted to survive on land? What are the benefits of living on land rather than in water?
Answer:
Sample Response: Plants that are able to survive on land developed specialized vascular tissue such as xylem and phloem. This vascular tissue aids in the transport of water and other resources needed by the plant. Land plants also developed a cuticle, or waxy layer, to prevent water loss and seeds to protect young plants. The benefits of living on land are greater access to sunlight and less competition with other plants for resources.

Are all electrolytes the same in their indications? Explain
Answer: Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help Balance the amount of water in your body.Balance your body's acid/base (pH) level .Move nutrients into your cells, Move wastes out of your cells, Make sure that your nerves, muscles, the heart, and the brain work the way they should. Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance. Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

A) cytokinesis.
B) cell cleavage.
C) cell differentiation.
D) gamete fertilization
Answer:
C) cell differentiation.
Explanation:
Cell differentiation is a process undergone by a cell in which it changes to a specialized form. During the process of cell differentiation, some genes in a single cell becomes turned off or on in a process called GENE EXPRESSION to give rise to cells with specialized functions.
This is the case of this sponge whose specialized cells perform unique functions like ingesting food, support, and reproduction. The specialization of the cells within the sponge is as a result of the process of CELL DIFFERENTIATION.
