What is the U.S. customary system of measurement?
What is matter?

Answers

The US customary system of measurement is the name of the system of measurements the US uses. It is our term of measurement, for example, inches, feet, yard, miles, etc.


Matter is the physical substance in general, and the description of it

hope this helps
The US customary system of measurements is the basic structure of units in the US that is used to calculate the distance, weight, or volume of things. Many of these include yards, feet, ounces, inches, etc...

Matter is the scientific term for anything and everything that takes us space.

How can a scale model be used to represent the relative distances between celestial bodies in the solar system

Answers

A solar system is a group of planets and other space material orbiting (going around) a star. In our solar system, that star is better known as the Sun and the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

The solar system models you’ve seen before probably don’t show how much bigger some planets are than others, or, more importantly for space travel, how far away the planets are from the Sun and each other. The Earth is about 150 million kilometers (93 million miles) from the Sun. Because this distance is so important to us Earthlings, it has been given a special name, called the Astronomical Unit (A.U.) for short. The Earth is one astronomical unit from the sun. Planets that are closer to the Sun than the Earth have a measured distance of less than one A.U. while objects farther from the Sun than Earth have a measured distance of greater than one A.U.

A maize plant with genotype Aa Bb produces the following gametes 100 Ab 45 AB 106 aB 50 ab This tells us that the two genes are likely on different chromosomes. True False

Answers

Answer:

True

Explanation:

The linkage relation of two genes can be determined on the basis of calculating recombination frequency.

If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.

In the given question, the  crossover gametes formed will be Ab = 100

and aB= 106.

Therefore,

Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.

Thus, True is the correct answer.

Choose all the answers that apply. The nervous system _____. A transmits nerve signals through blood.
B controls body functions,
C is only found in animals
D is made of the heart and blood vessels
E interacts with all other systems

Answers

Answer:

B controls body functions,

C is only found in animals

E interacts with all other systems

Explanation:

The nervous system is a network that sends messages in both directions between the brain and different parts of the body. It does this through the spinal cord, which runs down the back from the brain. It contains nerves inside, some filaments that branch off to the other organs and parts of the body.

The nervous system is a complex set of cells in charge of directing, supervising and controlling all the functions and activities of the body's organs.

Much of living beings, as well as humans, have nervous systems. However, there are organisms that do not have it, such as protozoa and porifers.

Answer:

The nervous system is present only in animals.

The nervous system also interacts with other systems.

It also controls body functions(the central nervous system does).

Saturated water vapor at 350 8 c is heated at constant pressure until its volume has doubled. determine the final temperature using the ideal gas equation of state

Answers

The answer is; 700 degrees Centigrade

This is derived  from the Boyle's Law, Charles's Law, and Gay-Lussac Law ideal gas equation  that is defined by the formulae; P1V1/T1 = P2V2/T2

Remember the P1 = P2  and V2 = 2*V1 in this case

P1*V1/350 = P1*2V1/T2

T2 = (P1*2V1/350)/ (P1*V1)

T2 = 350*2 =700

Which food contamination is best prevented by cooking to safe temperatures

Answers

Answer:

Cooking to safe temperatures will inactivate any kind of bacterial contamination, which was present. There is a need to keep the food safe from the danger zone, that is, between 40 degrees to 140 degrees F, as bacteria develop briskly in the mentioned range.  

There is a need to cook the food to safe internal temperatures. Just as the food looks done it does not mean that it is done. The best means to find that the meat, egg dishes, and poultry are cooked safely is to utilize a food thermometer.  

The safe internal temperature for all the meat mixtures and ground meat is 160 degrees F. There is a need to cook all the poultry to a safe internal temperature of 165 degrees F. As not cooking the food to safe temperatures signifies that bacteria may still be thriving within and may lead to illness on consumption.  

Follow these steps to prevent food poisoning: Wash hands, food preparation surfaces and utensils thoroughly before and after handling raw foods to prevent recontamination of cooked foods. Keep refrigerated foods below 40 degrees F. Serve hot foods immediately or keep them heated above 140 degrees F.

Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? Sodium ions can move down their electrochemical gradient through the cotransporter whether or not glucose is present outside the cell. Glucose entering the cell down its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient. A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose. The cotransporter can also transport potassium ions. Sodium and glucose compete for the same binding site in the cotransporter.

Answers

The correct answer is: A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose.

The Sodium Glucose Linked Transporters (SGLT) require the energy to transport glucose (uphill glucose gradient). They use that energy from this downhill sodium ion gradient created by the ATPase pump.  


The answer is A substance that blocks sodium ions from binding to the cotransport protein will also block the transport of glucose.

Sodium ions are necessary for regulation of blood and body fluids, transmission of nerve impulses, heart activity, and certain metabolic functions. Physiologically, it exists as an ion in the body. Sodium is needed by animals, which maintain high concentrations in their blood and extracellular fluids, but the ion is not needed by plants.
