Determine what kind of variation is related to the following trait: Pierced Ears.
A. Only Environmental variation
B. Neither
C. Only Genetics
D. Both Genetics and the Environment
Answer:
D. Both Genetics and the Environment
Explanation:
Getting a pierced ear is both a genetic and environmental trait because, in males, it is not genetically transferred, rather it is a choice to manually pierce the ear maybe at birth, or much later in life. In females, however, pierced ears is a genetic trait because it is gotten naturally when they are born
These environmental factors include where a person stays, the kind of friends they keep, and people they try to imitate. Ear piercing is something that is done manually for males for various reasons.
why do pk values of ionizable groups differ between free amino acids and amino acid residues in polypeptides
Answer:
Because of electrostatic interactions.
Explanation:
The pk values associated with ionizable groups are the result of the electrostatic interaction that occurs with the interaction of the ionizable side chain groups with groups of side chains that have charges, or that have neutral charges. This interaction directly influences the pk values of ionizable groups, leaving them different between free amino acids and amino acid residues in polypeptides.

The Krebs cycle is an aerobic
process meaning it needs what to
take place?
ОАТР
O Cartion dioxide
O Glucose
O Oxygen
Answer:
Oxygen
Explanation:
Kreb's cycle, also known as the Tricarboxylic acid cycle (TCA), is the second process of aerobic cellular respiration, after glycolysis. In the kreb's cycle, acetyl-CoA from pyruvic acid is oxidized to CO2 with the formation of 2 ATP molecules.
Krebs cycle occurs in the matrix of the mitochondria where chemical energy in form of ATP, NADH and FADH2 are produced. Krebs cycle is termed an AEROBIC process because it requires OXYGEN in order to occur.
Cigarette smoke contains thousands of chemicals, including nicotine and carbon monoxide. How do these two components of smoke affect the cardiovascular system?

mars facts and talk about mars
Answer:
Mars is a planet. It is the fourth planet from the Sun. It is the next planet beyond Earth. Mars is more than 142 million miles from the Sun. The planet is about half the size of Earth. A day on Mars is 24.6 hours. A year on Mars is 687 Earth days. Mars is known as the Red Planet. It is red because the soil looks like rusty iron. Mars has two small moons. Their names are Phobos and Deimos.
1) Named after the Roman God of war, Mars is the fourth planet from the sun in our solar system.
2) Mars is also known as the ‘Red Planet’ because, well, it’s red! This signature colour comes from the large amount of a chemical called iron oxide (or ‘rust’ as you might know it) in its rocks and soil.
3) Mars is the second smallest planet in the solar system after Mercury. With a diameter (distance through the middle) of 6,791 kilometres, it’s roughly half the size of Earth.
4) It can get pretty cold on Mars –– much colder than our own planet, since it’s further away from the sun. At the equator, temperatures can reach 20°C, but at its poles they can plummet to as low as -140°C.
5) Mars is home to the highest mountain in our solar system –– a volcano called Olympus Mons. Standing a whopping 24 kilometres high, it’s about three times the height of Mount Everest!
6)You could jump around three times higher on Mars than you can on Earth. This is because the planet’s gravity – the force that keeps us on the ground – is much weaker.
Hope it helps!!!!

Which of the following is responsible for sensing excessive stretch to protect the muscle?
A. Golgi tendon organ
B. Muscle spindle
C. Muscle fiber
D. Sarcomere
Answer: Muscle Spindle
Explanation: The muscle spindle is actually a specialized muscle fiber, which detects excessive stretch within the muscle. ISSA CPT Page 357
The thing that is responsible for sensing excessive stretch to protect the muscle is the golgi tendon organ, which is present in Option A as it is a sensory receptor located in the tendons of muscle fibers.
What is the golgi tendon organ?The golgi tendon organ is a type of proprioceptor, which is a sensory receptor that provides information about body position and movement, is located in the tendons of the skeletal muscles and is made up of sensory nerve fibers wrapped around collagen fibers within the tendon. When a muscle contracts, it generates tension in the tendon, which activates the sensory nerve fibers in the Golgi tendon organ, and the nerve fibers then send signals to the spinal cord for further work.
Hence, the thing that is responsible for sensing excessive stretch to protect the muscle is the golgi tendon organ, which is present in Option A.

What type of growth would you expect to see in a population that has migrated to a new habitat?
Answer:
Exponential growth
Explanation:

Which of the following is an extensive property? Boiling point Magnetism Melting point Volume
Answer:
Volume
Explanation:
The physical properties of matter are either classified as extensive or intensive. Extensive property of matter is a property that is dependent on the amount of matter contained in the substance. On the other hand, intensive properties are rather dependent on the type of substance and not the amount or size.
Based on this explanation, VOLUME is an extensive property because its measure is dependent on the amount of matter in the measured substance. Hence, a difference in the volume of two substances is as a result of the amount of matter contained in each of them.
On the other hand, boiling point, melting point and magnetism are all properties that depends on the type of matter.
