Answer:
The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. All sensations are electrical signals that travel through neurons which form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis.
Explanation:
The brain is an organ that controls the activity of the body, both its conscious and unconscious functions. It is located in the head and corresponds, therefore, to the encephalon of humans and other vertebrates and is subdivided into forebrain, midbrain and hindbrain.
The brain acts on the rest of the organism by generating muscle activity or by the production and secretion of chemicals called hormones. Thereby the brain controls responses to changes in the environment. Some basic types of response such as reflexes may be mediated by the spinal cord or peripheral ganglia, but sophisticated intentional control of behavior based on complex sensory information requires the integration of information.
The thalamus, which is located in the central part of the brain, processes and coordinates the messages from the senses that it receives from the body. Five senses are considered to exist: sight, touch, smell, taste and hearing. For that, the information perceived from the outside must reach the brain.
The senses are the components of our nervous system that capture stimuli from the environment for transmission to the brain, and it is there where the information is processed to issue a response. Therefore, all sensations perceived from the outside are electrical signals that travel through neurons. For example, the eyes transform light signals into electrical impulses, which travel to the brain where they are transformed into electrical signals.
Neurons form a network that communicates all organs with the center of the nervous system, and communicate with each other to transmit the electrical impulse through a process known as synapsis, which is mediated by molecules called neurotransmitters. Since the electrical impulse cannot jump directly from one neuron to another, these neurotransmitters are needed. When the active neuron produces them, the next neuron in the network detects them and becomes electrically charged. Once this has happened, it produces neurotransmitters again so that the next one becomes electrically activated. This is how the electrical impulse reaches the brain.

Explain the 5 ways to reach Hardy-Weinberg equilibrium, does this mean evolution is occurring?
There are five basic Hardy-Weinberg assumptions: no mutation, random mating, no gene flow, infinite population size, and no selection. If the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change).

Spend one minute writing an explanation of
the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE
Answer:
Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.
There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

How are genetic mutations passed from parent to offspring?
Answer:
Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation. There are also nonhereditary mutations that occur in cells outside of the germ line, which are called somatic mutations.
I hope it's helpful!
Answer:
★ Mutated gametes (sex cells) fuse to create offspring.
Genetic mutations or germline mutations can be defined as a permanent change in the DNA sequence of germ cells (cells, which form ovum and sperm). These mutations can pass from one generation to other when a mutated sperm or mutated oocyte (gametes) get fertilized with another oocyte or sperm.
A germline mutation, present in a single-celled zygote will present in all cells of a muticellular organism, a single-celled zygote divides and produces all of the cells in that organism.

A cell is placed in a hypertonic solution. Which will most likely occur as homeostasis is maintained in the cell?
A.
The cell will gain ATP molecules.
B.
The cell will gain water.
C.
The cell will lose water.
D.
The cell will lose sodium ions.
Answer:
B the cell will lose water
Explanation:
Because of the hypertonic solution water will move on the concentration gradient leaving the cell and entering the solution. Thus the cell looses water.
When a cell is placed in a hypertonic solution, it will most likely lose water (Option C) as homeostasis is maintained in the cell.
What is homeostasis?Homeostasis is the ability of an organism or a system to maintain a relatively stable internal environment, despite changes in external conditions. It is a key aspect of biology that helps living organisms survive in their environment. Homeostasis is maintained through a series of physiological processes that regulate different aspects of an organism's biology, such as temperature, fluid balance, and pH
A hypertonic solution is one that has a higher concentration of solutes (e.g. salts) outside the cell compared to inside the cell. This creates an osmotic pressure gradient, which draws water out of the cell and into the solution in an attempt to balance the concentration of solutes on both sides of the cell membrane. As a result, the cell will shrink and lose water.

Why can particles diffuse? Make it like a one sentence pls
[tex] - [/tex]
That's cause they have large spaces between them .
Particles can diffuse because the particles are too small and they do not have any define path, so they move from high density region to low density.
What is a particle?
"A particle is a small piece of anything. Particle can also refer to a subatomic particle with mass and structure, but takes up hardly any space at all. Particles are tiny."
What do you mean by diffuse?
"Diffuse means spread out over a large area."
What is diffusion?
“Diffusion is the movement of molecules from a region of higher concentration to a region of lower concentration down the concentration gradient.”
What causes particle to diffuse?
"Diffusion occurs due to the random movement of particles. It usually happens due to a concentration gradient, meaning that molecules move from an area of high concentration to an area of lower concentration."

In three to five sentences, construct an argument that shows why lichens are necessary to establish a new ecosystem after an extreme disturbance.
I would really appreciate it if someone o two people would help me out on this one
Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.

B. reduce FADH2 to FAD D. pump hydrogen ions across the membrane
Answer:
7. D. breaking the glucose molecule to produce acetyl CoA
8. C. Oxaloacetate
10. phosphorylate ADP to ATP
Explanation:
Cellular respiration is the metabolic process by which energy in form of ATP is obtained in a cell. However, it occurs in three major stages namely: glycolysis, Krebs cycle and electron transport chain (oxidative phosphorylation).
- Glycolysis is the process where glucose is broken down to produce pyruvate, which is then processed into acetyl coA before it enters the next stage (Krebs cycle).
- Krebs cycle is the stage where series of REDOX reactions occur to produce OXALOACETIC ACID as a final product, which accepts acetyl coA for another cycle to begin.
- Electron transport chain (ETC) uses the energy derived from the electron carriers energy NADH and FADH2 to phosphorylate ADP to ATP in a process called CHEMIOSMOSIS.
