Why does water have "surface tension"?
Answer:
Hello!
Explanation:
Surface tension in water owes to the fact that water molecules attract one another, as each molecule forms a bond with the ones in its vicinity. ... This inward net force causes the molecules on the surface to contract and to resist being stretched or broken. Hope this helps!
Explain How are speed and pressure of a fluid related?
Answer:
The higher the velocity of a fluid (liquid or gas), the lower the pressure it exerts. This is called Bernoulli’s Principle. Fluid pressure is caused by the random motion of the fluid molecules. When the fluid speeds up, some of the energy from that random motion is used to move faster in the fluid’s direction of motion.

What is made possible by a high concentration of auxins in a plant's shoot and root
tips?
a) hydrotropism
b) thigmotropism
c) phototropism
d) gravitropism
Answer:
phototropism
Explanation:
Auxins promote stem elongation, inhibit growth of lateral buds (maintains apical dominance). They are produced in the stem, buds, and root tips. ... This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance.
Phototropism made possible by a high concentration of auxins in a plant's shoot and root
The correct answer is C
What does a plant's phototropism entail?A plant can maximize photosynthetic light absorption in the aerial portion and water and nutrient uptake in the roots by using phototropism, or the differential cell elongation displayed by a plant organ in response to directed blue light.
What occurs during phototropism?
Positive phototropism, or growing toward the light, is the term for how a plant stem reacts to light. A negative phototropism, or root growth away from the light, is the term used to describe how a plant root reacts to light.

Carbohydrates are the source of energy thus the molecules that are used here are the energy molecules in the process of food metabolism as well.
What is the best source of carbohydrayte ?It is the whole grains, fruits and vegetables.
Along with the proteins and fats there are carbohydrates that are one of these three main nutrients that are in the foods and drinks. Our body is breaking down into the carbohydrates into the glucose. Glucose or blood sugar is main source of the energy for our body's cells, tissues and organs.
The primary role of the carbohydrates is to supply out the energy to the all of the cells in body. Many cells are preferred as the glucose that are a source of the energy where the other compounds as the fatty acids.

Answer:
Water separates polar molecules from each other by forming hydrogen bonds.
Explanation:
A polar molecule is a molecule in which the distribution of electrons between the covalently bonded atoms is not even. This means that one end of the bond is slightly more positively charged, while the other end is slightly more negatively charged.
An example of a polar molecule is a molecule of water (H2O). Substances with similar chemical characteristics dissolve in each other. This means that polar molecules will dissolve in water. The partially negative part of a water molecule will interact with the partially positive part of another polar molecule. This results in the formation of hydrogen bonds, which occur when a hydrogen atom is located between a pair of other atoms that have a high affinity for electrons.

Answer:
plant cells
Explanation:
Rosa could be looking at plant cells.
Plant cells are generally joined together when tissues of plants are viewed under the microscope and each cell is usually with a cell wall. Animal cells, on the other hand, do not have cell walls.
Tissues are generally composed of similar cells that have been aggregated together to perform a function in the body of organisms. Both plant and animal tissues consist of many cells but only plant cells have cell walls.
The temperature of the interior of the human body is about 37oC (98.6oF), regardless of the air temperature. Explain the importance of constant body temperature given the role of enzymes as catalysts in the body.
It is critical that we sustain an optimal temperature for our body's enzymes. When it gets too hot, our enzymes denature and become inactive/lost their function. If the temperature is too low, the enzymes will become ineffective.
What is homeostasis?Homeostasis is the state of constant internal, physical, and chemical assumption is supported by living systems in biology.
This is the state of the organism's optimal functioning, and it includes many variables, such as core temperature as well as fluid balance, getting kept within certain pre-set limits.
Enzymes can only function when the body's temperature remains constant. As a result, homeostasis becomes an important part of the body's metabolism.
Homeostasis maintains optimal conditions for enzyme action and all cell functions throughout the body.
It is the preservation of a constant internal environment in the face of changing internal and external conditions. These include blood glucose concentration control in the human body.
Thus, having an optimum temperature is essential in functioning of enzymes.
