Justify why the pituitary gland is the master hormone
A. It stimulates the production of other glands hormones
B. Its located at the brain
C. It is the strongest gland
D. It is the most intelligent gland
Answers
Answer:
The correct answer is - A. It stimulates the production of other gland's hormones.
Explanation:
The pituitary gland is also known as the "master" gland of the endocrine system. It stimulates or regulates other glands and the secretion of hormones of many of the other endocrine glands.
Its ability to control the function of the other glands and hormones gives it its name of master gland. The size of this gland is like a pea and found at the base of the brain.
The cells were kept in a dilute salt solution. They were then transferred to distilled
water.
Explain what will happen to each of these two cells when they are placed into distilled water.
Answers
When plant cells are placed in salt solution their appearance is different to when they are placed in distilled water. ... Therefore, water moves out of the cell across the partially permeable membrane by osmosis and the cell becomes flaccid as the cell membrane peels away from the cell wall
When these cells are placed in distilled water (pure water with no dissolved salts in it), water molecules from the distilled water move into the cell by osmosis. This can lead to cell lysis.

Yeast undergo anaerobic respiration (fermentation), where glucose is broken down into two (2) ATP and two (2) pyruvate. This pyruvate is then used to form what waste product?
Answers
The pyruvate is then used to form Ethanol [tex][C_2H_5OH][/tex] and Carbon dioxide [tex][CO2_][/tex].
What is Anaerobic respiration?Anaerobic respiration is defined as respiration using an electron acceptor other than molecular oxygen where oxygen is not the final electron acceptor, the process still uses the respiratory electron transport chain.
Anaerobic respiration is described as the process in which there is incomplete oxidation of glucose in the absence of oxygen which is commonly known as fermentation.
One type of fermentation is alcohol fermentation where the pyruvate is decarboxylated [tex](CO_2 leaves)[/tex] to form acetaldehyde. Hydrogen atoms from NADH+. H+ are then used to help convert acetaldehyde to ethanol. NAD+ results.
Thus, the pyruvate is then used to form Ethanol [tex][C_2H_5OH][/tex] and Carbon dioxide [tex][CO2_][/tex].

The student wants to see the cells at a greater magnification. Describe the steps that she should take.
Answers
Gradually turn the crude focus knob until you can see the cells. Turn the fine focus knob slowly until the cells are in focus and visible.
What is magnification?Magnification is the process of enlarging something's apparent size rather than its physical size.
This enlargement is measured by a calculated number known as "magnification." When this number is less than one, it refers to a size reduction, also known as minification or de-magnification.
The magnification of a compound microscope is the product of both lenses, so if the microscope has a 10x eyepiece and a 40x objective, the total magnification is 400x. Magnification is defined as the ratio of the image size to the object size.
The student should use the adjustment knobs to bring the sample back into focus after selecting the x40 or x10 objective lens.
Thus, these steps are necessary to see cell's magnification.

A population of 1000 birds exists on a small Pacific island. Some of the birds are yellow, a characteristic determined by a recessive allele. The others are green, a characteristic determined by a dominant allele. A hurricane on the island kills most of the birds from this population. Only ten remain, and those birds all have yellow feathers. Below are several statements about this hypothetical situation. Please write 1-6 and next to each number write T if true of Fif false.
1) Assuming that no new birds come to the island and no mutations occur, future generations of this population will contain both green and yellow birds.
2) Assuming that no new birds come to the island and no mutations occur, future generations of this population will contain only yellow birds.
3) This situation represents diversifying selection. 4)This situation represents directional selection.
Answers
Answer:
1) False
2) True
3) False
4) True
Explanation:
(3 and/or 4 may be wrong, but 1 and 2, i'm positive they aren't0
1 is false and 2 is true because recessive alleles x recessive alleles = reccessive alleles, and since yellow is recessive, and you have no green birds, there is no possibility of having green birds without at least one green bird parent.
(I hope that makes sense)
I believe 4 is true because Directional selection occurs when a single phenotype is favored, which is what happens here.
I'm not too sure about 3 though, sorry

HELP!!!! FAST!!!! 20 POINTS!!!! You are a traffic accident investigator. You have arrived at the scene of an accident. Two trucks of equal
mass (3,000 kg each) were involved in a rear-end accident at a stop sign. Here is what you know:
• Truck 1 started from rest at the top of a 22-meter hill and coasted toward the intersection.
.
Truck 2 was on a flat stretch of road at the bottom of the hill directly in front of Truck 1.
At the bottom of the hill, Truck 1 was going 20 m/s; Truck 2 was going 35 m/s.
.
There were no skid marks left by Truck 2. The collision occurred at the stop sign where Truck 2 had
stopped
• After the collision, both trucks moved together in the same direction at 10 m/s before slowly rolling
to a stop.
You must now push Truck 2, using 1,000 N of force, 8 meters off to the side of the road so no one
else gets hurt.
1. How much work was done to bring truck 2 to a stop? 2. If tuck 2 came to a stop In 15 seconds, how much power (in watts) did it take to stop truck 2 at the sign by applying force to the brakes? 3. What is the final combined momentum of the trucks right after the accident? 4. Assuming that there are no other no conservation forces involved, what impulse was given to each truck during the collision? A. Truck 1: B. Truck 2:
Answers
Answer:
1) Kinetic energy of the truck 1 is 600,000 joules.
Kinetic energy of the truck 2 is 1,837,500 joules.
2 a)Potential energy of truck 1 is 646,800 Joules.
b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.
Step-by-step explanation:
Mass of the truck 1 and truck 2,m = 3000 kg
Velocity of the truck 1, = = 20 m./s
Velocity of the truck 2, = 35 m./s
1. Kinetic energy of the truck 1:
Kinetic energy of the truck 2:
2.a) Energy loose by the truck 1:
Initial height of the truck on the hill = 22 m
At that height potential energy will be maximum:
Potential energy of truck 1 at that height =
b) Energy lost by the truck 1 just got converted into heat and sound energy during the collision.

Compare the movement of oxygen and carbon dioxide across the cell membrane. (4 marks)
help pls answer in paragraph form :)
Answers
Answer:
Molecules naturally disperse from areas of higher concentration to lower concentration.
As oxygen-rich (and carbon dioxide-poor) blood travels by a cell the oxygen diffuses through the cell membrane to the area of lower concentration inside the cell. It can do this easily because the oxygen molecule (O2) is very small and has no charge or polarity. The oxygen is used up rapidly by mitochondria. This rapid consumption causes oxygen to constantly move into the cell from the blood.
The mitochondria creates carbon dioxide (CO2) as a waste product of cellular respiration (the process that makes energy for your body). Because the CO2 is of a higher concentration in the cell than in the blood passing by, this gas continually diffuses out of the cell. It too is small and uncharged so it can pass through cell membranes easily.
These movements require no energy (in the form of ATP) on behalf of the cell.
