Describe three different measures that can be obtained from a single age distribution graph comparing males and females of a given population.
A single age distribution graph comparing males and females of a given population can provide a wealth of information. Three of the most important measures that can be obtained from such a graph are the population size, the age structure, and the gender ratio.
What is the way to measure the population size ?The population size can be determined by adding the total number of males and females represented in the graph. This is an important measure of the overall population size, and can be used to compare the population size of different countries or regions.
The age structure of the population can be determined by looking at the distribution of males and females across different age groups. This is an important measure of the demographic makeup of a population, and can be used to identify trends in population growth or decline.
Finally, the gender ratio of the population can be determined by comparing the number of males and females in each age group. This is an important measure of the overall gender balance in a population, and can be used to identify areas where there is a need for greater gender equality.
In conclusion, a single age distribution graph comparing males and females of a given population can provide a wealth of information. Three of the most important measures that can be obtained from such a graph are the population size, the age structure, and the gender ratio.

C. Betweentwoanomericcarbonsinpolysaccharides
D. Internal bond formation between the anomeric carbon of a monosaccharide and
its own fifth carbon hydroxyl group.
E. Between the carbon containing the aldol or keto group and the α-carbon of the
sugar.
The best describes the bond that can’t be broken is B. Between the anomeric carbon of a sugar and an OH (or N) of another molecule
Glycosidic bonds are a class of covalent bonds that joins a carbohydrate molecule to another group.
A polysaccharide (where poly means 'many') is a long chain of monosaccharides linked by glycosidic bonds.
Glycosidic bonds are formed between the hemiacetal group of a saccharide and the hydroxyl group (OH) of another compound (e.g., alcohol).

An investigator wishes to use animals in an experiment that involves USDA pain category B, C, and D activities performed on the same animal. How should the animal be categorized
The animals used in an experiment that involves USDA pain category B, C, and D activities performed on the same animal should be categorized to USDA category D.
The USDA pain categories are used to categorize the level of pain an animal used in testing and research will be exposed to. The categories are as follows:
USDA B: the animal will not feel pain of any kindUSDA C: the animal will feel the occasional slight painUSDA D: Painful procedures that will be mitigated by pharmaceuticals.USDA E: Painful procedures that will not be mitigated.Category B states the animal will not feel pain. Animals in this category are often used for breeding, which is a natural process that does not cause animal distress or pain.
Animals in category C may feel the occasional slight pain which is allowed to subside naturally without the use of pharmaceuticals. This may include procedures such as
Drawing blood samplesInjectionsAnimals in category D are exposed to painful or stressful procedures and will receive anesthetics and other chemical agents to mitigate or completely relieve the pain, Whereas E category animals do not receive said assistance.
These categories follow a strict rule. Animals must be categorized according to the most painful procedure it will undergo, so because the experiment will use USDA B, C, and D procedures, the animals must be placed into USDA category D.

Describe the disadvantages of an open circulatory system relative to a closed circulatory system.
Explanation:
The disadvantage of a closed circulatory system is that with the blood always contained in vessels, it's under higher pressure. This means it can flow faster, which is necessary for supporting the metabolic rate of more complex animals such as vertebrates. Open circulatory systems are low-pressure systems that cannot meet the needs of a fast metabolism.

Most physical characteristics are inherited. Scientists have discovered several genes that contribute to human fatness, particularly genes that regulate the production of specific ____________ , such as ____________ , which stimulates hunger, and ____________ , which reduces hunger.
Answer:
hormones; ghrelin; leptin.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
Heredity refers to the transfer of traits (specific physical characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.
A gene can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Over the years, scientists have discovered several genes that are known to contribute to human fatness (body weight), especially genes that are saddled with the responsibility of regulating the production of specific hormones, such as ghrelin, which stimulates hunger, and leptin, which reduces hunger.
When does facilitated diffusion occur?
-When one liquid has a higher osmotic pressure than the other.
-When certain large molecules are unable to move through the membrane
without the help of channel proteins.
-When ATP is available to assist in moving molecules.
-When there's a strong membrane potential present, with the inside of the cell
being more negative than the outside of the cell.
Answer:
When certain large molecules are unable to move through the membrane without the help of channel proteins
Explanation:
Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.

Species that require open grazing areas may not survive. b.) Species will quickly adapt and re-populate the area. c.) The environment on the habitat edges will support different plants and animals. d.) Subpopulations of species may emerge.

Environmental scientists cite several challenges to protecting endangered species. Which of the following is NOT a difficulty faced by those working to protect an endangered species? Scientists who are focused on a single species may not recognize another species in peril. Extinction is natural in nature and its rate of occurrence has remained steady. Protection efforts may be slowed because of difficulty enforcing new regulations. Fundraising can be more difficult if the species is not perceived as valuable.
Answer:
Extinction is natural in nature and its rate of occurrence has remained steady.
Explanation:
As of right now we are going through what is known as the sixt extinction, and human acticity is one of the Main causes. (which has never happened before our time) Species are going extinct at a rapid rate, and considering how all life is connected it makes it easy to understand why the extinction rates can increase due to a biotic factor (niche) being "removed".

What does the QRS complex represents as??
Answer:give me brainliest
Explanation:
A combination of the Q wave, R wave and S wave, the “QRS complex” represents ventricular depolarization. Ventricular depolarization occurs in part via an accessory pathway (AP) directly connecting the atrium and ventricle and thus capable of conducting electrical impulses into the ventricle bypassing the AV-His Purkinje conduction system.This term can be confusing, as not all ECG leads contain all three of these waves; yet a “QRS complex” is said to be present regardless.
Explanation:
QRS complex represents as ventricular depolarisation
