Winding mills are made on hills. Why?
Answer:
Winding mills are made on hills because of air flow and currents.
Explanation:
Winding mills capture wind to turn blades and produce energy. In order to do so, it needs winds! Strong winds, in order to turn the blades. You will notice that if you ever scale a mountain or go higher, it starts to become windier/the wind blows harder.
If the wind mills are placed higher, it can capture these windier conditions, thus moving the wind blades to produce energy. The higher the hill, the stronger the wind current, the more energy it produces.

What are the five parts of skill related fitness. Please select all 5 below. Question 1 options: Speed Muscular Strength Coordination Agility Balance Aerobic Endurance
Answer:
There are only four parts of skill related fitness in the options; they are:
Speed
Agility
Balance
Coordination
Explanation:
Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.
However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:
- Speed: This refers to the ability to run a distance in a short time frame.
- Agility: This is the ability to move easily and quickly in different directions
- Balance: The ability to maintain an upright body position during training or physical activity
- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.
Note that, Aerobic Endurance and Muscular strength are health-related components of fitness
Which one of the following molecules would be most likely to travel by facilitated diffusion? A. sodium ions B. glucose C. oxygen atoms
Answer:
The correct answer is : the sodium ion and glucose both shows the facilitated diffusion.
Explanation:
Facilitated diffusion is form of diffusion of molecules of solutes with the help of transport proteins along their concentration gradient on the plasma membrane, however it is a passive transport as its does not require energy to move in or out of cell.
Oxygen can move through the membrane directly by simple mean of diffusion. however, Other molecules like amino acids, ions, glucose and many more need a integral pore, channel or transport molecule to pass through the membrane or with facilitated diffusion.
Glucose transporters involves to help in movement of glucose through the membrane along the concentration gradient it shows facilitated diffusion. Sodium ions also move through along concentration gradient by protein channels formed by transport proteins through hydrophobic membrane.
Thus, the sodium ion and glucose both shows the facilitated diffusion.
Answer:
B. Glucose
Explanation:
Facilitated diffusion is important for the living organisms as there are lipid insoluble, polar and large molecules that needs assistance to diffuse across plasma membrane. These molecules are large and polar in nature so they need assistance. The ion channels or carrier proteins allow such molecules ( glucose) to cross the membrane. The two classes of protein that facilitates the diffusion are channel protein and carrier protein.
Summarise the differences between the nervous system and the endocrine system on the body’s coordination. Nervous System / Endocrine system How is the signal sent throughout the body? How quickly does the signal travel? What does the signal do to the target cells? How long does the effect of the signal last?
The nervous system signals the endocrine system to release
hormones in response to a stimulus.
The nervous system respond to stimulus through action potentials and neurotransmitters and they signals the endocrine system to secrete hormones.
The endocrine system is responsible for secreting hormones into the blood which is transported to the target cells. These hormones are responsible for metabolism , growth and response to stress. The hormones secreted provide feedback to the brain so as to affect neural processing.
Developing countries, such as Ethiopia, are areas where there is low technological advancement and poor standard of living. A major issue in these countries is malnutrition, which means they do not have access to enough nutrients for their bodies to perform all their normal functions and can lead to higher death rates. Often individuals in these countries live primarily on a single staple grain such as rice. Children living in these conditions will have similar characteristics such as extremely thin arms and legs.
What key macromolecule might be missing from children in this condition?
Answer: protein

An ecological footprint is the
A. Mark a persons shoe makes in soft earth
B. Number of animals a person has killed
C. Amount of land and ocean area needed to support one person
D. Number of trees people cut down
Answer:
C. Amount of land and ocean area needed to support one person.
Explanation:
The ecological footprint of a person is the amount of land or resources that are required for the maintenance and survival of a person. In simpler terms, it is the level of impact that an individual has in terms of the productive land and resources required for the person to survive.
This ecological footprint allows scientists to check and keep track of the impact of human activities in terms of the land and water used by an individual for his/ her survival. And this date will provide details about any biologically productive land or water areas, giving an estimate of the area needed to provide the renewable resources for the perpetual cycle of nature for the individual.
Thus, the correct answer is option C.

Carrie is conducting an experiment on a solution. The solution's initial pH is 3.2. Then, as Carrie gradually adds Compound X into the solution, the pH increases to 9.8. Which is the most likely identity of Compound X? A. a strong acid, such as hydrochloric acid (HCl) B. a strong base, such as sodium hydroxide (NaOH) C. a salt, such as sodium chloride (NaCl) D. a solvent, such as water (H2O)
Answer:
B
Explanation:
The correct answer would be a strong base, such as sodium hydroxide (NaOH).
The pH of a substance represents the degree of acidity or basicity of the compound. The pH scale ranges from 0 to 14 with 0 being the most acidic, 14 being the most basic, and 7 being a neutral pH. a pH below 7 is acidic and above 7 is basic.
A solution with an initial pH of 3.2 is acidic and in order to raise the pH to 9.8, it will require a strong base. Hence, compound X must be a strong base such as sodium hydroxide.
Correct option: B
Answer:b

The _____ was a direct result of the Industrial Revolution.
O improvement in quality of life
O shift to domestic foods over wild foods
O decrease in urban areas
Answer:
Option: Improvement in quality of life
Explanation:
The industrial revolution resulted in a significant improvement in the quality of life for the working class. However, it was slow, irregular, and sometimes missing through many years. The evidence of increasing incomes and improving mortality rates indicate significant improvement took place in the pattern of living of the working class. These factors suggest that the quality of life at least continued firm, and presumably developed. This progress took place with constant warfare with factory owners and government intervention. The Industrial Revolution introduced new machinery, the transformation of cities. The rapid growth of cities and towns beginning to take place with a change in society.

Answer:
microtubules. actin filaments and intermediate filaments
The cytoskeleton is the internal structure that maintains the shape of the cell and is made up of proteins that polymerize into filamentous structures.
What are proteins?They are biomolecules made up of structural units called amino acids.
The cytoskeleton is a protein-based system found in cells that provides internal support and is constructed of three main types of filaments (proteins), these are microtubules, microfilaments, and intermediate filaments.
Therefore, we can conclude that the cytoskeleton is the internal structure that maintains the shape of the cell and is made up of proteins that polymerize into filamentous structures.
