How can 2 locations roughly the same distance from the equator (the same amount of sunlight) have such a different climates?
Answer:
Explanation:
Latitude or distance from the equator - Temperatures drop the further an area is from the equator due to the curvature of the earth. The humid subtropical climate is generally located between 25° and 35° latitude on the east sides of continents. Also, temperatures decrease as you move away from the equator.

Nutrients Nutrients are substances in food that supply the body with energy and raw materials needed for growth, repair, and mainteNnce. The nutrients that the body needs are water, carbohydrates, fats, proteins, vitamins, and minerals.
- Many of the body's processes take place in water. Water makes up a large part of blood and other body fluids.
- Simple and complex carbohydrates are the body's main source of energy. Complex carbohydrates, such as starches, must be broken down into simple sugars to be used for energy.
- Fats are formed from fatty acids and glycerol. Fats help the body absorb fat-soluble vitamins and are a part of cell membranes, nerve cells, and certain hormones.
- Proteins supply raw materials for growth and repair of structures such as skin and muscle. Many enzymes and hormones are proteins.
- Vitamins are organic molecules that the body needs in very small amounts. They are needed to help the body perform chemical reactions.
- Minerals are inorganic nutrients the body needs in small amounts. Examples of minerals include calcium and iron.

When a chemical reaction does not occur, what happens to the atoms of the reactants
Answer:
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. ... No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

A student is creating a T chart of prokaryotic vs eukaryotic cells
T chart of prokaryotic cell vs eukaryotic cell.
Prokaryotic cell size is generally small ( 0.5-10um ).Nuclear region is not surrounded by nuclear membrane. Membrane bound organelles such as mitochondria, Lysosomes, endoplasmic reticulum are absent nucleus is absent. cell division is by fission or budding ( but no mitosis ).they always have single chromosome. DNA is circular and lies free in the cytoplasm. DNA is nàked( not associated with proteins or RNA to form chromosome) eg - found in PPLO bacteria and blue green algae. Eukaryotic cell they are larget in size (1-100um)Nuclear region is surrounded by a nuclear membrane. all the membrane bound organelles are present. nucleus present. cell diviis mitotic or meiotic.they have more than one chromosome. DNA is linear and contained in a nucleus. DNA is associated with proteins and RNA to form chromosomes. e.g found in plants and animals other than PPLO and blue green algae.A friend tells you that plants only need water to grow. do you agree? explain.

1. How do you think your organs work together to digest food?
2. What other inventions do you think are based on the functions of the digestive system?
3. How might you be able to tell that enzymes are working in your body?
4. How do different types of food change the number of digestive enzymes present in your body?
Answer:
1. Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.
2.The SmartPill is an ingested, wireless device for measuring the health of the digestive system. As it passes through the digestive tract, the capsule transmits data to a receiver, which is later returned to the doctor and the information downloaded onto a laptop computer.
3. When its not working many of the uncomfortable reactions such as an upset stomach, allergy-like symptoms or irritability are actually signs that the enzymes are working. The body is cleaning itself out and the healing process is starting.
4.One of the main reasons for reduced output of digestive enzymes is poor exocrine pancreatic function. The causes of Exocrine Pancreatic Insufficiency (EPI) are very diverse ranging from: Problems with the endocrine part of the pancreas such as insulin dysregulation from diet high in refined carbohydrates and diabetes.

The electrical impulse of the heart normally begins at the:.
Answer:
SA node (sinoatrial node)
Explanation:
SA node (sinoatrial node) – known as the heart's natural pacemaker. The impulse starts in a small bundle of specialized cells located in the right atrium, called the SA node. The electrical activity spreads through the walls of the atria and causes them to contract. This forces blood into the ventricles.

1. (b) How does transpiration provide water for essential life processes in plants?
Answer:
Concentration gradient forces the water to flow passively from the soil to the root, and to move up through the stem in the xylem and evaporates through stomata in the leaf. In such a way transpiration provides water for essential life processes in plants.
Which organ is the site of gas exchange?
Answer:
lungs
Explanation:
lungs
During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs. This happens in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
The lungs exchange gases
3. What is the difference between saponifiable and nonsaponifiable lipids?
Answer:
the difference is that unsaponifiable lipids do not contain fatty acids at least not as a component of the fundamental structure whereas saponifiable lipids do have fatty acids.
Explanation:
As a further explanation unsaponifiable lipids are lipids that do not contain fatty acids as components of the fundamental structure. On the other hand, complex also known as saponifiable lipids do contain fatty acids, and those fatty acids can be released in a process called saponification which is caused by alkaline hydrolysis.
what is inside your capillaries that carries oxygen to your heart?
Answer:
Capillaries are narrow blood vessels. Blood contains plasma, red blood cells, white blood cells and platelets. Red Blood cells are bi-concave disc which contains hemoglobin that reacts with oxygen and thus oxygen is transported by RBC to the heart where it is distributed to the whole body
Veins are present inside your capillaries that carry oxygen to your heart. While arteries perform the opposite function which carries blood away from the heart.
What are the functions of capillaries?The functions of capillaries are as follows:
Capillaries transport blood, oxygen, and nutrients to every cell. They are the type of delicate blood vessels that exist throughout your body. They also exchange waste throughout the body.Capillaries also help in the connection of arteries and veins.Capillaries are the connection link of both arteries and veins. So, both arteries and veins perform their specific function in order to facilitate the transport of deoxygenated blood and oxygenated blood to and from the heart respectively.
Therefore, the structure inside your capillaries that carries oxygen to your heart is known as veins.

The roof of an eco-house is covered with soil. Covering the roof with soil decreases the thermal conductivity of the roof. What are the two of the choices listed below are advantages of having a roof with a lower thermal conductivity?
1) Less energy is needed to heat the house.
2) The rate of energy transfer by conduction is greater.
3) The roof is a better insulator.
4) The roof is less likely to leak.
5) Weather will have a greater effect on the temperature of the house.
Answer:
To understand how insulation works it helps to understand heat flow, which involves three basic mechanisms -- conduction, convection, and radiation. Conduction is the way heat moves through materials, such as when a spoon placed in a hot cup of coffee conducts heat through its handle to your hand. Convection is the way heat circulates through liquids and gases, and is why lighter, warmer air rises, and cooler, denser air sinks in your home. Radiant heat travels in a straight line and heats anything solid in its path that absorbs its energy.
Most common insulation materials work by slowing conductive heat flow and convective heat flow. Radiant barriers and reflective insulation systems work by reducing radiant heat gain. To be effective, the reflective surface must be in contact with an air space.
Answer:
Explanation:
A thick layer of material with a low thermal conductivity reduces the rate of heat transfer from the ceiling into the roof space.
