Explanation:
Controlling the level of sugar in the blood is an example of a feedback mechanism
The feedback mechanism man is a physiological regulation system that is found in a living body that works to return the body to the normal or earlier internal state. It is commonly called the homeostasis mechanism.
This feedback loop can be seen in any day-to-day function such as a rise in blood pressure levels, which results in the increase of insulin secretion in the body. An increase in physical activity leads to an increase in respiratory rate and the homeostatic mechanism will gradually lead to the body to the previous state.Thus the option 1 is correct.

Which of the following statements about muscles and the muscular
system is true? *
All muscle action is voluntary, or able to be consciously controlled.
The three types of muscle tissue are skeletal muscle, smooth muscle, and involuntary
muscle.
Muscles always work independently to move parts of the body.
Smooth muscle moves food through the digestive system.
Answer:
Smooth muscles nice food through the digestive system
Explanation:
Cardiac muscle movement is involuntary. Think about how you can't stop your heart from beating (I wish lolol).
The three types of muscle tissues are cardiac, smooth and skeletal.
Muscles work with each other all the time. Remember muscles are only able to pull the bones in one direction, so even simple things like chewing require lots of muscles pushing and pulling at your jaw.
The statement that is true about muscles and the muscular system is:
Smooth muscle moves food through the digestive system.What are muscles?They are the main soft structures that are part of the musculoskeletal system of the human body.
Characteristics of the muscular systemThere are three essential types of muscle: cardiac, smooth and skeletal.Most muscles can be controlled at will and allow enough force to be exerted on the skeleton to move us.Smooth muscle is also known as visceral or involuntary, it is located in organs of the abdominal and pelvic area, it is composed of different cells, it helps to move and degrade food products.Therefore, we can conclude that muscles are soft structures that have the ability to contract and produce movement.

A local population of bobcats has decreased by 10% over the last 10 years. Is this change in population significant enough for the bobcat species to be considered for the Endangered Species List and protection from the government?
Yes, because any change in population even if it has a wide habitat range and large global population is cause for concern and the government should help that population recover.
Yes, because the local population decrease means the other populations are also decreasing even though the species has a wide habitat range and large global population.
No, because a small change in a local population of a species with a wide habitat range and large global population is not cause for concern.
No, because it will probably just go extinct and another predator will take over it's habitat even though it has a wide habitat range and large global population.
Answer:
No, because a small change in a local population of a species with a wide habitat range and large global population is not cause for concern.
Explanation:
Population change can be defined as the change in the number of individuals of a given species in an area during a specific time interval. Local populations may suffer small changes in their size but it generally does not represent an important problem for the survival of these species. A species is classified as endangered when its population size is reduced in a percentage from 50% to 70% within a period of time of ten (10) years. These values and the corresponding list of endangered species have been developed by The International Union for Conservation of Nature (IUCN), which represents the opinion of more than 8,000 researchers worldwide.

You are now trying to map a new gene locus (Gene X) on chromosome 9. You have determined that the recombination frequency between Gene X and Gene A is 12.5%, recombination frequency between Gene X and Gene B is 25%, and the recombination frequency between Gene X and Gene C is 31.25%. Use this information to determine the location of Gene X. Show your work and explain your reasoning.
Answer:
The correct order of genes might be: C, B, A, X (or X, A, B, C)
--C------------B--------------------A-------------------X----
∫-----------------------31.25mu---------------------∫
∫-----------------25mu-----------------∫
∫-----12.5mu----∫
Explanation:
Available data:
the recombination frequency between Gene X and Gene A is 12.5%,the recombination frequency between Gene X and Gene B is 25%, the recombination frequency between Gene X and Gene C is 31.25%.We need to know that 1% of recombinations = 1 map unit. The map unit is the distance between the pair of genes for which one of the 100 meiotic products results in a recombinant one.
The recombination frequencies between two genes determine their distance in the chromosome, measured in map units. So, if we know the recombination frequencies, we can calculate distances between the four genes in the problem and we can figure the genes order out. This is:
Recombination frequencies:
1% of recombination frequency = 1 map unit (MU)
A-X = 12.5% = 12.5 mu
B-X = 25% = 25mu
C-X = 31.25% = 31.25 mu
We do not know the distances between A-B, A-C, and B-C, so we can just estimate the location of the gene X by its distances from genes A, B, and C. To do this we need to think about it as additions. We know that A-X = 12.5 mu, a distance duplicated by B-X = 25 mu (12.5 + 12.5 = 25), and X is farther away from B than from A, so, this might tell us that A is located between B and X.
---B--------------A--------------X------
∫-------------25mu----------∫
∫--12.5mu----∫
Now, we know that X-C = 31.25 mu. And, assuming that these are linked genes, the maximum recombination frequency is always 50%. So the distance between two genes can not exceed 50%. According to this, we might assume that the C gene is near B, because if it was on the other side of X, the distance between B-C would sum 56.25 mu (25 + 31.25), meaning that they would not be linked. So, the correct order might be
--C------------B--------------------A-------------------X----
∫-----------------25mu-----------------∫
∫-----12.5mu-----∫∫-----12.5mu----∫
∫-----------------------31.25mu-------------------∫
∫6.25mu∫
∫------------18.75mu---------∫
The location of Gene X is closest to Gene A located 12.5
Given that :
The recombination frequency between Gene X and Gene A is 12.5%
The recombination frequency between Gene X and Gene B is 25%
The recombination frequency between Gene X and Gene C is 31.5%
The recombination frequency represents the map distance between the genes on the linkage map and the lesser the value of the recombination frequency the more linked are the genes.
The sequence in the linkage map is attached below
Hence we can conclude that the location of Gene X is closest to Gene A located 12.5

A teen's crash rate is highest .
A. When they turn 18.
B. right after they get their license.
C. driving during the day.
Answer:
A. when they turn 18. it's more likely
Teenagers have a higher crash rate right after they get their driver's license. Therefore, option B is correct.
This period is often referred to as the "novice driver" phase. It is a time when new drivers, including teenagers, are less experienced and may lack the necessary skills to handle various driving situations effectively.
During this phase, newly licensed teenagers may still be adjusting to the responsibilities of driving independently. They may not have encountered or developed strategies for handling different road conditions, traffic scenarios, or unexpected events.

D
When the material has a high specific heat.
Answer:
B
Explanation:
The addition of heat results in a rapid temperature rises when the material has high specific heat. Thus, the correct option for this question is D.
What is Specific heat?Specific heat may be defined as the quantity of heat that is significantly required in order to enhance the temperature of one gram of a substance by one degree Celcius. The units of specific heat are typically represented in calories or joules per gram per Celsius degree.
When the material has a high latent heat of vaporization. It illustrates that heat is remarkably needed in order to alter the phase of the substance without stimulating any change in the temperature. So, as per the question, latent heat is not the correct concept to describe.
Therefore, when the material has high specific heat, it will result in a rapid temperature rise. Thus, the correct option for this question is D.
