Answer:
❑How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)? 4
❑How much do you depend on natural ecosystems for the food you eat? 5
❑How important is preserving natural ecosystems to you? 5
❑How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future? 4
Explanation:
The questions are closely related to ecosystemic services and how humans make use of it. Let us first review theoretical concepts, and then discuss the rating of the questions.
Ecosystem services refer to all the benefits that human beings can get from ecosystems, not only for survival but also for good life quality. There are four types of ecosystem services:
• Provision or supply:
These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials, raw materials (used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others.
• Regulation:
Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pest/plague control, etc.
• Cultural:
Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, learn, enjoy spiritual/religious space, and are a source of inspiration. It is considered to be cultural patrimony and the source of scientific knowledge.

I answered the questions from my personal point of view, and considering 5 as the most important topic, and 1 as the less important. So, from most important to less important is 5, 4, 3, 2, 1.
❑How much do you depend on natural ecosystems that you use for recreation (camping, fishing, hunting, hiking, swimming, boating)?
Probably, we as species, do not need these activities to survive. However, we need them to have good mental health. These are activities that we enjoy and that produce satisfaction. Whenever we do things that we enjoy our organism secretes hormones that make us feel happy. This feeling is important when people are stress about any personal situation. So, this question does not get the highest rate, but it gets a significant one, a 4.
❑How much do you depend on natural ecosystems for the food you eat?
Basically, we depend on nature and the ecosystem to get food and any kind of supply. If the ecosystems are damaged and altered, there is a general disbalance, and every form of life is affected. Some species might even get extinct. If we keep damaging the environment as we are doing currently, we will get to the point of not having any supply available to survive. So this is one of the most important questions, which gets the highest rate, a big 5.
❑How important is preserving natural ecosystems to you?
This question is closely related to the anterior one. It is very important for us as a species to realize that we depend on nature 100%, that we need to take care of it and preserve ecosystems all around the world. With no healthy and equilibrated ecosystems, we do not get to survive. So this is the other question that gets the highest rate, 5.
❑How willing are you to sacrifice things in your life to make sure that natural ecosystems stay unharmed in the future?
This one is kind of difficult to answer, We could say that we are 100% willing to sacrifice to make sure ecosystems stay unharmed. However, we are so used to consumption, technology, confort, an easy lifestyle, and etc, that would be really difficult for us to sacrifice everything that we are used to. Just imagine yourself giving up your cellphone or your computer. Technology is one of the most polluting industries in the world. But we depend so much on it, that seems almost impossible to imagine us without it. This is why my score for this question is a 4. Personally, I surely would sacrifice too many useful things, but I find it hard to sacrifice some others.

6. What is the relationship between genes and alleles?
Answer:
A gene is a unit of hereditary information. Except in some viruses, genes are made up of DNA, a complex molecule that codes genetic information for the transmission of inherited traits. Alleles are also genetic sequences, and they too code for the transmission of traits. So, what it is the difference between a gene and an allele? The short answer is that an allele is a variant form of a gene.

Propose what happens to sodium and potassium ions during hyperpolarization.
Answer:
En biología, la hiperpolarización es cualquier cambio en el potencial de membrana de la célula, que hace que esté más polarizada. Es decir, la hiperpolarización es un incremento en el valor absoluto del potencial de membrana de la célula.
During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell, leading to an overall increase in the negative charge within the cell.
What is hyperpolarization?Hyperpolarization is a process that occurs in cells, particularly in neurons (nerve cells). It is characterized by an increase in the negative charge within the cell, which results from the movement of ions across the cell membrane. During hyperpolarization, sodium ions are pumped out of the cell and potassium ions are pumped into the cell. This results in a more negative charge inside the cell, which can inhibit the cell's ability to respond to stimuli.
Hyperpolarization is the opposite of depolarization, which is a process that leads to a decrease in the negative charge within a cell and an increase in the cell's excitability. Hyperpolarization can be triggered by various stimuli and plays a role in the normal functioning of the nervous system.

After you eat lunch, nerve cells in your stomach respond to the distension (the stimulus) resulting from the food. This is best described as a mechanism between:
Answer:
stimulus, control center
Explanation:
The control center is the main nervous system of the brain that is used to carry out different sensory, the motor and integration of data.
The stimulus control is the behavioral control that is described as the situations where behavior is triggered by the presence or the absence of any stimulus. Stimulus is the functional reaction in a tissue or any organ.
In the context, the nerve cells in the stomach responds to the stimulus that results from the foods after eating food is a mechanism between the stimulus and the control center.
list few points on the importance of sun in power supply.
Answer:
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.

¿Cuál es la molalidad de una disolución al mezclar 4 kg de agua como disolvente con 0,5 Mol de ácido clorhídrico (HCl) como soluto?
Answer:
La molalidad de la disolución es 0,125 molal.
Explanation:
En la teoría de las disoluciones químicas, la molalidad se define como la cantidad de moles del soluto dividida por la masa de solvente, entonces tenemos que la molalidad de la disolución descrita en el enunciado es:
[tex]m = \frac{0,5\,mol}{4\,kg}[/tex]
[tex]m = 0,125\,m[/tex]
La molalidad de la disolución es 0,125 molal.

Why do only certain cells respond to particular signaling molecules that are sent throughout the body
Answer:
The presence of appropriate receptor dictates which cells will be receptive to a particular signal.
Explanation:
Some cells only respond to certain molecules because they have receptors to accept those molecules. Hence, due to this, only some molecules can be accepted by the cells.
How does a particular cell accept the molecules?Hormones are secreted by endocrine glands into the blood. The endocrine glands, such as the pituitary gland, secrete their hormones directly into the blood, but not all cells of the body can bind to the molecule and perform the cellular functions.
The cells' surface has receptors for molecules such as peptide molecules or polar hormones that can't directly enter the cell. Hence, they bind to the cell surface receptors and send signals with respect to those hormones.
A hydrophobic hormone can directly enter the cell as it can easily pass the plasma membrane. After entering the cell, it has some receptors in the nucleus or in the cytoplasm. This hormone can perform functions such as gene activation after binding with them.
Hence, after binding with receptors, they show their performance, and not every cell has the same receptors for a single molecule.

One of the ways that food can be preserved is by heavily salting it so that bacteria cannot live upon the food. What causes the bacteria to die in an extremely salty environment? Group of answer choices
Answer:
Dehydration
Explanation:
What causes bacteria to die in an extremely salty environment is dehydration due to the loss of osmotic balance in their cells.
Water molecules would normally move from the region of high water potential or low solute concentration to the region of low water potential or high solute concentration through a biologically permeable membrane.
An extremely salty environment would be hypertonic to the cells of bacteria and the cell walls of bacteria act as biologically permeable membranes. Hence, the bacteria cells lose water due to the osmotic movement of water from their cells to the surrounding salty environment.
Autoclaving is the most effective among all moist heat-related antimicrobial methods. (True or False)
Answer:
True.
Explanation:
Autoclaving is the most effective among all moist heat-related antimicrobial methods because this method can kill all the harmful microbes such as bacteria, fungi and viruses. Moist heat causes destruction of microorganisms by denaturation of macromolecules that is present in their body such as proteins. Autoclaving is a very common method for moist sterilization. It is an effective method in killing fungi, bacteria, spores, and viruses but it does not eliminate prions.

when measuring the blood pressure, the cuff is deflated until two consecutive beats are heard through the stethoscope. This measurement reflects
Answer: Systolic pressure.
Explanation:
Every time the heart beats, it pumps blood into the arteries, which are vessels through which blood circulates from your heart to your tissues with the oxygen and nutrients they need. Blood pressure is the force of the blood pushing against the walls of the arteries, and is highest when the heart beats, pumping blood, which is measured as systolic pressure (i.e., when the heart contracts). On the other hand, diastolic blood pressure refers to the pressure of blood in the artery when the heart relaxes between beats (i.e., when the heart relaxes). Since there are two types of pressures, blood pressure readings are given in two numbers, with the top number being the systolic pressure and the bottom number being the diastolic pressure.
For example, if the systolic pressure measured in a person is 125 millimeters of mercury (mm Hg) and the diastolic pressure is 85 mm Hg, the blood pressure is recorded as 125/85.
So, the systolic blood pressure is registered with the stethoscope when the cuff is deflated. When two heartbeats are heard, the pressure gauge reading is recorded. When the heartbeat ceases, the cuff pressure is released and the diastolic pressure is measured at this time.

Answer:
Due simple growth.
Explanation:
Neurospora is an ideal organism to study the effects of genetic mutations because it is easier to growth and are simple. Neurospora crassa is used as a model organism because it has a haploid life cycle and easier to grow that makes genetic analysis simple. Analysis of genetic recombination is facilitated by the ordered arrangement of the products of meiosis in Neurospora ascospores so due to simple growth and haploid life cycle we can considered Neurospora is an ideal organism.
