2. You step outside on a 90 degree summer day. After 1 minute. your body beginsto sweat. As the sweat evaporates off your skin, heat is lost from the body andyour internal temperature begins to decrease.ChoosePositive feedbackNegative feedback
The hypothalamus tells the eccrine sweat glands throughout the body that it's time to sweat and cool down.
Increased sweat gland recruitment but also increased perspiration per sweat gland. Also, dehydration fluid loss and associated plasma hyperosmolarity and hypervolemia reduce sweating volume and sensitivity and increase the sweating threshold. As the body continues to warm up, the heart beats faster and the blood draws closer to the surface of the skin.
Your blood vessels will dilate your skin will turn rosy and you'll begin to sweat lovingly. Sweat seeps through your pores and evaporates, taking heat away from your body. As the heart rate increases, more blood is pumped from the outside of the body and through the skin, causing excess heat loss to the surroundings and sweating. These changes place additional demands on the body. Altered blood flow and excessive sweating reduce physical and mental performance.

This image of a roller coaster is designed to show important information about potential and kinetic energy. One of these labeled pieces of information is incorrect. Which information is wrong, and why?
A. The spot with the “maximum kinetic energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
B. The spot marked “maximum gravitational potential energy” should be on the lowest point of the roller coaster, at the far left side on the bottom.
C. The roller coaster would only have kinetic energy at the point labeled “gravitational potential energy and kinetic energy.”
D. The roller coaster would only have potential energy at the point labeled “gravitational potential energy and kinetic energy.”
According to the scenario of the Roller coaster, the one label piece of information that is incorrect is the roller coaster would only have kinetic energy at the point labeled “gravitational potential energy and kinetic energy.” Thus, the correct option for this question is C.
What is Kinetic energy?Kinetic energy may be defined as a type of energy that is significantly acquired by motion. It is energy that is possessed by an object or thing due to its motion. So, this energy is also known as energy due to motion.
According to the context of this question, the kinetic energy is stored throughout the roller coaster except for the point "maximum gravitational potential energy."
So, the option is fairly untrue or incorrect because it is saying that the roller coaster would only have kinetic energy at the point labeled “gravitational potential energy and kinetic energy.” While kinetic energy is found to be highest at the point of "maximum kinetic energy."
Therefore, the correct option for this question is C.

Explain why giraffes have long in your explanation include the role of the environment,selective pressure, 3 ingredients to NS, The effect on the population and allele frequency
This is a classic example used in evolution however is used only to explain differences between Lamarckian theory and Darwinian theory, nonetheless with recent tools can be explained in more detail.
Classically is proposed a population of giraffe with certain variations in neck length, this is given by genetics and alleles, all populations possess a certain pool of variation, now according to Darwin the giraffes with longer necks were selected as their fitness survival was increased due to this trait, Giraffes with longer necks could access to more vegetation and nourish better, in consequence, reproduced more than those of short neck, also when competing intraspecifically among giraffes those with longer necks were better competitors increasing also their survival rate, in time giraffes with short neck were extinguished and selective pressure continue favoring those of long neck, this in genetics meant the fixation of the allele of long neck and an increase in the frequency of the same.

We must discover the location on a graph where the population line is horizontal in order to determine carrying capacity there.Alternately, a dotted horizontal line or a horizontal line of a different color may be used to expressly identify the carrying capacity.Biologists often graph populations to show growth trends. A graph that reveals an “s” shape indicates that the population has hit its carrying capacity.The amount of predators and prey that may coexist in a region is referred to as the carrying capacity.Predators starve and die because they can't locate enough food when there are too many predators and not enough prey. The population of predators frequently rises after periodic increases in the number of prey.The prey population declines as the predator consumes its prey. In practically every situation, there are more prey than predators, as shown by the graph.It also exhibits the patterns listed below:When there is more prey, there are more predators.When there are more predators, there are less prey. The ratio of predators to prey is fairly consistent in a thriving, balanced ecosystem.Although they may increase and decrease during the year, they tend to stay pretty steady over time.A change in abiotic variables, like water or sunlight, or biotic factors, like a new predator or pathogen, could be the cause of an increase or reduction in the numbers of either predators or prey.A less healthy, unbalanced ecology would arise from this.

What happens to the rate of blood delivery if your heart rate increases
A) blood delivery rate increases
B) it has no impact on blood delivery rate
A) blood delivery rate increases happens to the rate of blood delivery if your heart rate increases.
Does a faster heartbeat result in more blood flow?Healthy blood arteries will enlarge when your heart beats more quickly to accommodate more blood flow, which aids in keeping your blood pressure largely steady. This is frequently true when you exercise since your heart rate may rise significantly yet your blood pressure may just slightly fluctuate.
This is due to the fact that any increase in heart rate also shortens the time that diastole lasts, which hinders coronary blood flow.
Blood flow increases as a result of vasodilation, which is brought on by smooth muscle cells in arteries relaxing. Blood flow is boosted as blood vessels widen because vascular resistance is reduced. Therefore, arterial blood pressure and heart rate immediately drop as a result of artery and arteriole dilatation.

Cells are the basic unit of the body of any organism.
Understanding how they work in various environments help to develope medicines or medical treatments. Knowing the process and how the cells of a determined part of the body work, you can develope medicine that will focus on that part and not have a general effect through all the body.
By knowing their basic needs, you can improve their functions by giving them the nutrients they need, this way, the organism will grow better. For example, if you want that a crop is more effective and the plant produces as much food as possible, knowing what it cells need will help out to improve the production.
