Answer:
The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body. THE DEGISTIVE TRACT begins at the mouth and ends at the anus. It is like a long muscular tube, up to 10 metres long, with digestive organs attached along the way.

explain how cactus leaves and stems might have changed through the process of natural selection
Answer:
Leaves were generally lost as a water conservation measure so that transpiration would not drain the cactus of water in its desert environment. Stems grew into large reservoirs to hold any water brought into the cactus.
Describe the role of competition in the simulation?
Answer: Competition ensures the survival of the fittest.
Explanation: The better characteristics and genes can be passed on.
Answer:
Competition can sometimes be viewed as not always necessary in an organisation especially when it comes to training; however I oppose this idea, especially in the context of business simulation games. There are various advantages of creating healthy competition within a business simulation game environment, just like in the real business world:

Review Map D. Predict future weather for New Orleans, LA. What weather might occur there? What is the cause of this weather? Predict the future weather for Washington, DC. What is the cause of this weather?
Answer:
1. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.
2. As the warm moist air rises, towering clouds often form releasing energy in the form of brief, intense rain storms with high winds and lightning. On the other hand, warm fronts will ride up and over cold air near the surface. As it rises, the air cools and the humidity condenses to form clouds and precipitation.
Explanation:
An increase in ATP levels would tend to ____________ the PDH complex. Activate inhibit phosphorylate
An increase in ATP levels would tend to inhibit the PDH.
The oxidation of pyruvateAfter the break down of glucose through the metabolic pathway known as glycolysis, the end product, pyruvate, is converted to acetylChoA in the citric acid cycle.
Pyruvate dehydrogenase (PDH) is the first enzyme of the citric acid cycle that is activated by its substrate pyruvate and inhibited by its products acetylChoA together with Adenosine Triphosphate (ATP).
This means that an increase in ATP negatively regulates the enzyme, pyruvate dehydrogenase.
Therefore, an increase in ATP levels would tend to inhibit the PDH.

1. Why is diffusion important for living organisms?
2. Define concentration gradient.
3. What is the effect of concentration gradient on the rate of diffusion?
4. What is the effect of surface area on the rate of diffusion?
Answer:
1. because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
2.The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse. The direction of diffusion is said to be 'down' or 'with' the concentration gradient.
3.The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.
4.The greater the surface area, the faster the rate of diffusion.

What are 3 thing created by genetic engineering??
Internal adaptations are the traits created by an evolutionary process whereby a population becomes better suited to its habitat by adapting the function of its internal structures. What is an internal adaptation birds have that makes them well suited for flight? A) Beak B) Hollow bones C) Smooth feathers D) Crop and gizzard
Answer:
B) Hollow bone
Explanation:
Air sacs are attached to the hollow areas in a bird's bones. Essentially, their lungs extend throughout their bones. This helps birds take in oxygen while both inhaling and exhaling. This adds more oxygen to the blood, providing a bird with extra energy for flight.
Answer:
B hollow bones

A human cheek cell's cycle is 24 hours. The stages within the cell cycle vary in length. G1 phase - 11 hours, G2 phase - 4 hours, S phase - 8 hours, M phase - 1 hour. Why does the cell spend 23 hours in interphase (G1-S-G2), while it spends only one hour in the M phase?
a.Interphase consists of the Gap 1 and Gap 2 phases, in which the cell is dormant while the chromosomes align.
b.Interphase is when cells are dormant while they decide whether they want to replicate their chromosomes.
c.Interphase follows mitosis, when daughter cells double their chromosomes, which takes 23 hours.
d.Interphase takes a long time because it is a preparatory stage where the cell makes proteins and organelles and doubles its chromosomes.
Answer:
answer is c
Explanation:
The cell needs a lot of preparation and checks in G1, S and G2 to do mitosis. especially in the G1 phase which is the longest phase. It is explained by the fact that the cell should "rest and recover" after the last mitosis before getting into the second one

6. List What types of
particles make up a
carbon atom?
Answer:
The subatomic particles in the nucleus of a carbon atom are protons and neutrons.
Explanation:
The atomic nucleus contains protons and usually neutrons (except for hydrogen-1 (protium) atoms. The number of protons is an element's atomic number and is the same for all atoms of an element. Carbon has atomic number 6. So all atoms of carbon have 6 protons in their atomic nuclei. Carbon atoms also contain neutrons in their atomic nuclei, which may number 6, 7, or 8.
