Assume that plant height is determined by a pair of alleles at each of two loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 6 feet to height and that each allele represented by a lowercase letter contributes 2 foot to height. If a plant with genotype AaBB is crossed to a plant with genotype aaBb, what heights are expected in the progeny
Answers
Answer:
16 feet, 20 feet, and 12 feet
Explanation:
Uppercase allele = 6 feet
Lowercase allele = 2 feet
First, let us look at the outcome of the cross between AaBB and aaBb.
AaBB x aaBb
Progeny:
4 AaBB = 6+2+6+6 = 20 feet
4 aaBB = 2+2+6+6 = 16 feet
4 AaBb = 6+2+6+2 = 16 feet
4 aaBb = 2+2+6+2 = 12 feet
The heights expected in the progeny are 16 feet, 20 feet, and 12 feet.

To protect our rights, the Constitution divides powers between the federal government's branches. This principle is called "separation of powers." Each branch of government holds distinct but equal authority. For example, Congress has the power to create laws, while the president has the power to execute these laws. The preamble states the purpose of "securing the Blessings of Liberty." Our freedoms are secured when power is not concentrated in any single branch of government. This helps our government to provide for our needs while respecting our rights.

Explanation:
Separation of powers is very important and crucial in federal type of government. This is helpful because it decentralized the power, and prevent one arm of government from being a dominating force.

An aquarium with a glass lid is an example of an isolated system.

false
Answers
Answer:
The answer is false!
Explanation:
I took the K12 science quiz. I hope this helps! Have a blessed day! :)
The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.
What is an aquarium?An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.
Aquariums are made up of glass, and they are open from the top so that fish can get air.
An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.
Therefore, the statement is false.

Explanation:
One primer attaches to the __ end of the gene region on the 5' to 3' strand, another to the ___ end of the gene region of the 3' to 5' strand. This was maybe not explicit in the video. 3’ and 5’ refer to the orientation of the DNA strand. The 3’ end is the end that has the OH group used for adding new nucleotides. The 5’ end is the end where a phosphate sticks out from the ribose. The two strands that make up the DNA molecule run anti parallel to each other. Synthesis is always in the 5’ to 3’ direction (because that is where new nucleotides attach), and the template strand is read 3’ to 5’ (because it runs antiparallel).
Answers
Answer:
Explanation:
This question is incomplete however during DNA amplification using polymerase chain reaction, the two primers attach to each DNA strand at the 3' end.
Two primers are used during this process; one primer each for the two complementary strands of DNA (that run antiparallel to each other). The 5' end of each primer is attached to the 3' end of each DNA strand regardless of the direction the strand is running (5' to 3' or 3' to 5'). This process of attaching the primers to the DNA strand is known as annealing.

Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answers
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
