Select each of the following that are recessive alleles represented in the genotype AaBb.
A
B
a
b
Answer:
small a and small b because the big ones are dominant the others recessive
The recessive alleles represented in the genotype AaBb is a and b.
What is recessive and dominant allele?Alleles can be dominant or recessive. We call someone dominant who has achieved a certain characteristic. The recessive can only express itself in pairs.
Thus, as it is a pair and knowing that the recessive alleles are shown with lowercase letters we have to be ab.

How do trees offset our carbon footprint? Put an x in each box that applies
Trees absorb carbon dioxide from The atmosphere and turn it into oxygen
Trees help limit the amount of greenhouse gasses in our atmosphere
Trees absorb oxygen from the atmosphere and turn it into carbon dioxide
Trees are great for shade
Answer:
Trees absorb carbon dioxide from the atmosphere and turn it into oxygen
Explanation:
Trees help to offset our carbon footprint by absorbing carbon dioxide from the atmosphere and turning it into oxygen.
Trees are often regarded as carbon sinks because they take in more carbon dioxide than they release.
The process of photosynthesis is one that allows plants to use carbon dioxide and water in the presence of sunlight to produce their own food. In this process, oxygen is the by-product.

How can you account for the great number, size, and complexity of organic compounds?
Answer:
Explanation:
"how can you account for the great number, size, and complexity of organic compounds? carbon can bond with so many elements. It can bond with itself and form long chains. Also, all macromoleculse are composed of C,H,N, and O."
Organic compounds number in the millions, far outnumbering inorganic compounds. The reason for this is due to the uniqueness of carbon's structure and bonding abilities.
What are organic compounds?Any of a wide range of chemical compounds in which one or more carbon atoms are covalently linked to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.
Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.
Organic compounds in the body include carbohydrates, lipids (including phospholipids), proteins, nucleotides, and nucleic acids.
Water (H2O), bimolecular oxygen (O2), carbon dioxide (CO2), and some acids, bases, and salts are the most important inorganic compounds. The human body is 60-75% water.
Organic compounds outnumber inorganic compounds by orders of magnitude. This is because of the uniqueness of carbon's structure and bonding abilities.
Thus, this way, one can account for the great number, size, and complexity of organic compounds.

Mitosis and Meiosis.
Answer:
The first one is meiosis because you split the chromosomes in half, to get 23 chromosomes from each parent. The second one is mitosis because you double it, and then bring it back to 23 chromosomes. Mitosis goes through PMAT twice.

Two cars with different masses travel at the same speed down a hill toward a stop sign. What will happen when both cars apply brakes at the same time to stop?
F- The car with the smaller mass will require less force to stop than the car with the larger mass.
G- The car with the larger mass will maintain its velocity while traveling down the hill.
H- The car with the smaller mass will take longer to stop than the car with the larger mass.
J- The car with the larger mass will have less inertia than the car with the smaller mass.
Please mark answer and Give explanation
Answer:
F
Explanation: The car with the smaller mass will require less force to stop than The car with the larger mass that is it
The car with the smaller mass will require less force to stop than the car with the larger mass.
What is law of inertia?The law of inertia or Newton's first law of motion states that an object at rest or uniform motion in a straight line will continue in that form unless it is acted upon by an external force.
This law is called the law of inertia because it depends on mass of the object.
The object with more mass will required more force to be stopped while the object with less mass will require less force to be stopped.
Thus, the car with the smaller mass will require less force to stop than the car with the larger mass.

What might happen if you make a hole using a pointed object to any of the two small
balloons?
Due to high pressure on the small hole, the balloon will burst.
The balloon will burst if we make a hole using a pointed object because there is a lot of pressure on the small opening. When we male a hole in a balloon with a pointed object such as needle, the air inside the balloon trying to escape from the small opening which puts pressure on the small hole which the balloon can't tolerate and as a result the balloon will burst so we can say that the balloon will burst due to presence of high pressure.

Answer:
The epicenter and hypocenter are two important points in causing earthquakes.
Both the epicenter and hypocenter are different from each other in the following basis:
Location: Hypocenter is present within the earth surface where an earthquake rupture starts and the epicenter is located in the earth's crust just above the hypocenter where a seismic rupture begins.
Associated waves: Seismic waves propagate from the hypocenter caused by seismic velocity and rock density which reaches the epicenter where P and S waves hit the surface of earth.

water and energy
carbon dioxide, water, and energy
carbon dioxide and water
carbon dioxide, water, and glucose
Answer:
[tex]\boxed {\tt Carbon \ dioxide, \ water, \ and \ energy}[/tex]
Explanation:
Cellular respiration is a process in the mitochondria to produce useable energy. The formula is:
oxygen + glucose ⇒ carbon dioxide + ATP + water
Oxygen and glucose go in to produce carbon dioxide, ATP or energy, and water. Therefore, oxygen and glucose are the reactants and carbon dioxide, energy, and water are the products.
The correct answer is B. carbon dioxide, water, and energy.
