Tillage can release pollutants in the soil and
increase erosion.
o decrease erosion
o promote soil compaction
O promote fertilizer retention
Answer:
Increase erosion because the soil is being loosened
Explanation:
Tillage can release pollutants in the soil and - option. increase erosion which is applied to conventional tillage.
The preparation of the soil by mechanical agitation such as digging, plowing, overturning, and other ways, in agriculture for the purpose of plantation and cultivation of crops.
Disadvantageous of Tillage:
causes an eventual loss of soil production.accumulating pollutants in topsoil due to the movement of the components present in the soil.Increases in erosion rates due to loose soil.The destruction of earthworm pathways and root channels leads to a decrease in the quality of the soil.Thus, the correct answer is - option. increase erosion

Macronutrients can be stored by the body for later use when it enters into the fasted state.
a. True
b. False
Answer:
a. True
Explanation:
The statement being made is true. The Fasted State is where our bodies draw from glycogen and fat reserves in order to create energy. This happens only when we do not eat that we enter into this state. The body first needs to draw all the energy it can from the glycogen stores and then once that is depleted it then begins to draw from fat stores for energy. Using all the stored macronutrients and turning them into energy to sustain the body.

PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surrounded by a membrane.
Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1

How is oxygen and carbon dioxide exchanged between the cells of the body?
Gas Exchange | Anatomy and Physiology II
Question 3 options:

both oxygen and carbon dioxide move from the blood into the cells of the body
carbon dioxide moves from the blood into the cells of the body, and oxgyen moves from the cells of the body into the blood
both oxygen and carbon dioxide move from the cells of the body into the blood
Answer:
oxygen moves from the blood into the cell and the cell uses it in cellular respiration and then the CO2 goes from the cell to the blood to get it back to the lungs to get rid of it

What can you conclude about starch, glucose and their movement across the Visking tubing? , What implications does this have for starch and glucose in the small intenstine?
Answer:
Starch molecules is too large therefore cannot pass through pores of visking tubing, glucose molecules is small enough to pass through pores of visking tubing. Visking tubing is like small intestine in this experiment, where starch is too large to be absorbed through small intestine into bloodstream, glucose is small enough to diffuse through small intestine and to be reabsorbed into bloodstream.

What is the answer to everything hypothetically?
The gecko is a reptile that has the amazing ability to climb smooth surfaces - even glass. Recent discoveries indicate that geckos stick to smooth surfaces via van der Waals interactions between septae on their feet and the smooth surface. When not selling car insurance, geckos climb smooth surfaces.
a. How is this method of stickiness advantageous to the gecko over covalent interactions?
b. Given that van der Waals forces are among the weakest molecular interactions, how can the gecko's feet stick so effectively?
Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.
Light waves are a type of electromagnetic wave.
The wavelengths of light range from 400 nm to 700 nm.
Light waves are transverse waves
• The speed of light is 3 x 108 m/s.
Which statement can be inferred from the data?
O Light waves can transport matter through mediums and empty spaces.
O Light waves transmit energy by compressing the particles in mediums.
O Light waves can travel with and without mediums.
O Light waves transfer the particles of mediums in the direction of travel.
Answer:
Light waves can travel with and without mediums.
Explanation:
Light waves are a type of electromagnetic wave. Some of the characteristics (properties) of light waves include;
I. The wavelengths of light range from 400 nm to 700 nm.
II. Light waves are transverse waves.
III. The speed of light is 3 x 10^8 m/s.
Therefore, from the aforementioned characteristics it can be inferred that light waves can travel with and without mediums.
This ultimately implies that, light wave is an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Maintaining blood glucose levels is an important homeostatic activity of the body, not specifically because every cell of the body must have glucose but primarily because the brain relies on glucose for its metabolism.
a. True
b. False
Answer:
a. True.
Explanation:
Even though the cells in our body rely on glucose as a source of energy, they can replace glucose's energy with lipids or proteins' energy. In the brain's case, this is not possible since the blood-brain barrier, which is a highly selective barrier between the blood and the extracellular fluid in the central nervous system, allows the passage of glucose as the only source of energy. This is why maintaining the correct levels of glucose is crucial for the metabolism in the brain.
