Which of the following sequences below show the correct pathway of food through the digestive system, after it enters the mouth?
A. Esophagus - Stomach - Intestines
B. Esophagus- Intestines - Stomach
C. Stomach - Esophagus - Intestines
D. Stomach - Intestines - Esophagus
E. Intestines - Stomach -Esophagus
F. Intestines -Esophagus- Stomach
The branch of science which deals with human functioning is called physiology.
The correct option to the question is option A.
The breakdown of food from the larger molecule to the smaller molecule is called digestion. The food goes into the mouth where it has broken down into smaller molecules with the help of teeth.
Afterward, it goes to the stomach via oesophasgus by the peristaltic movement.
Once food reached the stomach, it goes to the intestine where is being digested completely.
Hence, the correct option is A that is Esophagus - Stomach - Intestines

Why is it difficult for your body to return blood from your feet when you sit for too long?. Single choice. a. Blood has to travel a greater distance. B. Skeletal muscles are not squeezing the veins. c. Gravity makes the blood flow backward. d. The heart does not beat fast enough at rest.
Answer: Option C.
Gravity makes the blood flow backward
Explanation:
it difficult for your body to return blood from your feet when you sit for too long because gravity makes blood flow backward and this is because when you sit for long , it weakens the keg muscles because it is necessary for body movement so that blood will circulate or flow well. When the keg muscles becomes weak, it will slow blood flow in the leg and the force of gravity acting will make the blood flow backward and thus can cause a blood clot.

16. This diagram shows part of an aquatic food web from a stream near
several farm fields. Overuse of chemicals in fields near the stream has
polluted the ecosystem and killed off a large portion of the crustacean
population. Select any one of the other organisms in the food web and
provide evidence to explain what would happen to their population in this
scenario and WHY it would happen. Organism: State the organism you
chose. Explain WHAT would happen and WHY it would happen.
Answer:
There would be a increase in algae, and a slight decrease in fish.
Explanation:
there would be an increase in algae because crustaceans one of the two organisms that feed off of it. Fish are able to live off of insect larvae, but in turn there be a decrease in larvae , causing a decrease later in fish. If there's a decrease in fish, there will be a decrease in reptile, since the reptiles are the only organisms that are eating fish.

In a theoretical population in H-W equilibrium, 150/1000 have aa. For this population, what is p? what is q? Please answer honestly.
Answer:
The correct answer is :
q = 0.387
p = 0.613
Explanation:
According to the Hardy Weinberg equilibrium, the frequency of alleles or genetic variation remains constant from generation to generation if there is no external disturbance. Equilibrium of such kind in the real-world not possible however it is found to be effective for a theoretical population. H-W equilibrium can be represented with the help of an equation:
P²+ 2pq+q² = 1
here,
p^2 = AA (dominant same allele frequency)
2pq = Aa (heterozygous frequency)
q^2 = aa (recessive similar alleles frequency)
so from the equation:
Frequency of aa = q^2 = 150/1000 = 0.15
Frequency of 'a' = q = square root of 0.15 = 0.387
Freuqency of 'A' = p = 1- 0.387 = 0.613
what are the ideal conditions for photosynthesis? (Light intensity, Co2 levels, and temperature).
Answer:At medium temperatures, between 50 and 68 degrees Fahrenheit, or 10 and 20 degrees Celsius, the photosynthetic enzymes work at their optimum levels, so photosynthesis rates gauge high. Depending on the particular plant in question, set the greenhouse thermostat to a temperature within this range for best results.

The part of cell division that causes the separation of the cytoplasm is _____.
The following are sources of Earth's internal heat energy EXCEPT
a. Decay of radioactive isotopes
b. Primordial heat
c. pressure from overlying layers
d. Sun’s energy
The sun's energy is not a source of Earth's internal heat. So the correct option is D.
What is the earth's internal heat?
Nobody has even gotten close to directly examining the interior of the Earth. So there is disagreement among geophysicists as to how heated the Earth's core is. However, the speed at which earthquake waves, sometimes known as "seismic waves," move may reveal a lot to scientists about the composition of the Earth.
The solidity, liquidity, or partial solidity of these materials can also be determined using seismic data. Laboratory results, meanwhile, show what pressures and temperatures the materials inside the Earth should melt at.
The temperature of the Earth's core is thought to be between 5,000 and 7,000 degrees Celsius based on this information. That is far colder than the sun's inside, yet roughly as heated as the sun's surface.
Although the amount of heat created inside the Earth is immense, the amount of heat energy received from the sun is around 5,000 times stronger. The weather is influenced by the sun's heat, which ultimately leads to erosion. It is so paradoxical that although the heat of the Earth creates mountains, the energy of the sun gradually breaks them down again.
Therefore the correct option is D.

PLEASE HELP! What is the difference between cementation and stratification
Explanation:
Cementation is the process by which sediments are bonded together using some materials such calcium carbonate and iron oxide. This process of cementation helps to hold mineral grains together and give them thorough cohesion.
Stratification is the layering of sediments in a basin. The process by which sediments are deposited layer upon layer in a basin is known as a stratification.
The process of cementation often follows stratification after the sediment is in place.
15) Reread the information box Campaign to Reproduce. Write a paragraph about your opinion on the matter. Is the population decline good or bad? Do you think governments should try to get people to have more children? Include reasons to back your opinion. The paragraph must be at least five sentences.
Answer:
sorry but i need points
Explanation:
Less or low population is good for both us and environment.
Yes, decline in population of human is good because more resources are available for the present population and also reduce pollution. More people produces more pollution so less population is good for earth atmosphere.
No, in my opinion governments should not try to get people to have more children because more resources are required to feed the high population. The natural resources will be depleted at faster rate so we can conclude that less or low population is good for both us and environment.

Use the drop-down menus to identify which
groundwater zones are labeled in the image.
Label A
Label B
Answer:
Label A: saturated zone
Label B: unsaturated zone
Explanation:
The Label A indicates the saturated zone whereas Label B indicates the unsaturated zone.
What are ground water zones?Groundwater is found in two zones. The first is unsaturated zone, present just below the land surface that contains water and air in the open pores, or the voids pores.
The second zone is saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone. The top of the saturated zone is called the water table. The water table may found just below or may present hundreds feet below the land surface.
Thus, the label A and label B represents the unsaturated zone, and saturated zone of ground water respectively.

What is a variable trait in a population?
Answer:
Variable trait in a population refers to the differences in genetic composition in individuals.
The variable trait is very common and necessary as we all have different parents and the process of meiosis which takes place in sex cells involves the parent passing only one set of chromosome to the offspring and producing four unique daughter cells.
The implication of this is that individuals will definitely have their own unique characteristics also.
This helps to promote diversity within the population and ensure people living in a particular region which involves special features or ability are able to cope as the traits are imbibed in such individual.
