1: What gases are used and expelled by photosynthesis and respiration?
2: Where are the largest concentration of ozone and what value does it have?
3: What happens to the surface of the earth when there is an increase in greenhouse gases?
Answer:
1 Photosynthesis uses CO2 and expels O2 and the reverse for respiration
2. stratosphere where ~90% of it is
3. Less infrared radiation is able to escape from the earth into space and that infrared radiation hits the GHG gases and the radiation is turned into kinetic or heat energy trapping which warms up the earth
Explanation:
Answer:
1. Used by Photosynthesis: CO2 Expelled: O2
Used by Cellular respiration: O2 Expelled CO2
2. Most ozone (about 90%) is found in the stratosphere, which begins about 10–16 kilometers (6–10 miles) above Earth's surface and extends up to about 50 kilo- meters (31 miles) altitude. The stratospheric region with the highest ozone concentration is commonly known as the “ozone layer”
3. The surface of the earth heats up

The cell will ____________ in CORN SYRUP because _____________________________________________________.
Answer:
The cell will shrink because water can move in but proteins cannot move out.
Explanation:
Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink. This is also due to osmosis, but in the opposite direction. The corn syrup is mostly sugar.
Which is the correct sequence of the urine's pathway as it is formed and exited from the body?
urinary bladder, kidney, ureter, urethra
O kidney, urethra, urinary bladder, ureter
O urinary bladder, ureter, kidney, urethra
O kidney, ureter, urinary bladder, urethra
Answer:
Kidney, ureter, urinary bladder, urethra
Explanation:
Kidney, ureter, urinary bladder, urethra is the correct sequence of the urine's pathway as it is formed and exited from the body. Therefore, option (D) is correct.
What is Urinary tract?Urine, which contains wastes and extra fluid, is expelled from the body through the urinary tract, which serves as the body's drainage system. Urine is removed through the urinary tract. In order for normal urination to take place, it is necessary for all of the body parts that make up the urinary tract to cooperate with one another and do so in the appropriate sequence. The component of the body that processes urine and consists of two kidneys, two ureters, a bladder, and a urethra.
Infections can also occur in the urinary tract, and these infections are caused by microorganisms, most commonly bacteria, that enter the urethra and the bladder. These microorganisms are what cause inflammation and infection in the urinary tract. Even though a urinary tract infection (UTI) most frequently takes place in the bladder and the urethra, bacteria are able to travel up the ureters and infect your kidneys if they have the chance.

Both the liver and kidneys are organs of the excretory system. How do the two organs work together to complete a task?
Answer:
When the liver has broken down due to harmful substances, its by-products are exerted into the bile or blood. Bile by-products enter the intestines and leave your body in the form of feces. Blood by-products are filtered out through the kidneys and leave the body in the form of urine.
Explanation:
When the liver is damaged by harmful substances, their by-products move into the bile or blood, where the by-products of bile enter the intestines and leave your body as feces and by-products of the blood. -products are filtered through the Kidneys and leave the body as urine.
What is Excretion?Excretion is defined as the process in which metabolic waste is eliminated from an organism, this is done by the lungs, kidneys and skin in vertebrates.
This is in contrast to secretion, where matter may have specific functions after leaving the cell where excretion is an essential process in all forms of life.
Through excretion organisms control osmotic pressure which is defined as the the balance between inorganic ions and water and maintain acid-base balance.
Thus, when the liver is damaged by harmful substances, their by-products move into the bile or blood.

a squirrel dropped an acorn from a branch of an oak tree. which of these will change as the acorn falls from the tree to the ground? the mass of the acorn the density of the acorn the force of the acorn the velocity of the acorn
As an acorn is dropped form a branch of an oak tree, the force applied on the acorn changes which results in the dropping off of acorn seed. Thus, the correct option is C.
What is Force?A force is a push or a pull which changes the motion of an object. The fundamental forces are of four types such as: Gravity, Electromagnetism, Strong interaction, and Weak interactions.
Here, Gravitational force or gravity is applied during the dropping of an acorn seed form the oak tree. In some plants, seeds simply drop off on their own. However, some plants rely on the gravity to disperse off their seeds for pollination and other purposes. Seeds from the poppy plant emerge from their fruit such as a pepper drops from a shaker which allows a plant to form the colony around it.
Therefore, the correct option is C.

In a DNA strand, 80% of the strand is made up of adenine and thymine. How much adenine, thymine, cytosine, and guanine is made up in the strand
Answer: The perecentage of guanine is 30%
Explanation:
According to the Chargaff's rules the DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of purine bases [for the DNA cytosine, thymine and for the RNA uracil] and pyrimidine bases [guanine and adenine for RNA and DNA]. The amount of guanine should be equaled to cytosine and the amount of adenine should be equaled to thymine. You can follow this rule in both strands of the DNA.

A student wanted to see if covering a leaf in foil would stop it from producing starch. Why should the student put the plant in a dark cupboard for 48 hours before returning it to the light and starting the experiment?
1. To make the results reliable
2. So that the plant would photosynthesise faster when returned to the light
3. So that any starch already in the leaf was used up by the plant
4. He did that simply
Answer:
4.) He did that simply
Explanation:
I'm just guessing it's 1 because the other answers don't seem reasonable
Answer:
Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to the consumption of all stored starch making the leaf starchless. The correct answer is option D.

What are some water pollution management strategies, what do you think is the best one and why?
Answer:
There are plenty of things that we as individuals can do to slow down the amount of pollution going into the ocean, these could include not flushing anything down the toilet that won't disintegrate (because no matter where you live, all toilet pipes lead to the ocean), converting plastic use to reusable materials; this could include using reusable straws, water bottles, shopping bags, etc. and of course, when you need to throw plastic out, always recycle. :)
Explanation:
I believe the best way an individual can help the oceans is by converting plastics to reusable or at least eco-friendly products. If everyone made a conscious effort to do this, the oceans would be MUCH clearer.
Hope this helps!
