Answer:
Parents having blood type AB and O can produce offsprings having blood group A or Bbut not O
Explanation:
The possible blood type that could result in the offspring is it can be either A or b but not O as O is recessive.
What is blood?Blood is defined as a fluid that distributes oxygen and nutrients to cells while also removing carbon dioxide and other waste materials.
There are three types of blood cells.
RBC - RBC stands for red blood cells. They are defined as a kind of blood cell present in the blood that is produced in the bone marrow. WBC - WBC is also called white blood cells. They are defined as a kind of blood cell present in the blood and lymph tissue that is produced in the bone marrow.Platelets - Platelets are defined as the cells that circulate in our blood and link together when they detect damaged blood arteries.Thus, the possible blood type that could result in the offspring is it can be either A or b but not O as O is recessive.

Indicate whether each of the following statements about regulatory proteins is true or false.
1. Regulatory proteins control transcription initiation by modulating the ability of DNA polymerase to bind to the promoter.
2. Regulatory proteins function by binding to specific sequences on the DNA called regulatory sequence.
3. Hundreds of regulatory sequences have been identified and each one provides a binding site for a specific protein that is able to recognize the sequence.
4. In order to recognize and bind to the correct regulatory sequence, a regulatory protein must unwind and separate the two strands of the DNA double helix.
5. Binding of a regulatory protein to DNA either inhibits transcription by getting in the way of RNA polymerase or stimulates transcription by favoring the binding of RNA polymerase to the promoter.
6. Repressors are regulatory proteins that bind to RNA polymerase and act to prevent or decrease the initiation of transcription.
7. Activators are regulatory proteins that bind to enhancers and act to stimulate the initiation of transcription.

The nuclear DNA content of a single sperm cell in Drosophila melanogaster is approximately 0.18 picogram. What would be the expected nuclear DNA content of a primary spermatocyte in Drosophila
Answer:
The correct answer is - 0.72 pg.
Explanation:
A we know that, genetic material present in one primary spermatocyte divides in between four sperm cells that means that each sperm cell has 25 percent of DNA or genetic material of the primary spermatocyte.
Given:
1 sperm cell = 0.18 nuclear DNA
So,[tex]DNA content of one sperm cell = \frac{\text DNA content of primary spermatocyte}{4}[/tex]
0.18*4 = DNA content of primary spermatocyte
DNA content of primary spermatocyte = 0.72 picogram

Which of the following statements correctly compares transcription in prokaryotes and eukaryotes?
A. Bacteria have one type of RNA polymerase, whereas eukaryotes have at least three.
B. RNA polymerase in both prokaryotes and eukaryotes produce the same RNA molecules.
C. Both eukaryotes and prokaryotes recognize a polyadenylation signal in order to terminate transcription
D. Prokaryotes have at least three types of RNA polymerases, whereas eukaryotes only have one.
Answer: Which of the following statements correctly compares transcription in prokaryotes and eukaryotes?
Explanation: It would be B
The correct comparison between transcription of prokaryotes and Eukaryotes is that prokaryotes have one type of RNA polymerase, whereas eukaryotes have at least three.
Prokaryotes Transcription:
Only three promoter elements: -10, -35 promoters, and upstream elements. Prokaryotes have only one type. In prokaryotes, transcription and translation occur simultaneously.Polyadenylation do not occur in prokaryotes. Transcribed mRNAs in prokaryotes are polycistronic. In prokaryotes, termination is done by either rho-dependent or rho-independent mechanisms.Eukaryotic Transcription:
Eukaryotes contain many different promoter elements: TATA box, initiator elements, CAAT box, etc.There are three types of RNA polymerases, I, II, and III in Eukaryotes, The RNA is transcribe in the nucleus and then translate in the cytoplasm.Eukaryotic mRNAs are monocistronic.Termination is done by two elements: a poly(A) signal and a downstream terminator sequence.Therefore, the correct comparison between transcription of prokaryotes and Eukaryotes is that prokaryotes have one type of RNA polymerase, whereas eukaryotes have at least three.

Explanation:
When sugars are broken down to produce usable energy for cells, a large amount of heat is released. Explain how the water inside a cell helps to keep a cell’s temperature constant.
Answer:
Explanation:
This is due to the fact that water has high specific heath capacity,which makes it to accommodate large amount of heat energy produced by the catabolic reactions which liberated heat.
General, the amount of heat energy needed to raise the temperature of a particular substance over a given amount is called the specific heat capacity of that substance. Therefore for water, the amount of heat energy needed to raise the mass of 1kg of water by 1 degree is called the specific heat capacity of water.
Since large hydrogen bonds held water molecules together,it takes a long time of heat energy to break these bonds free to raise the temperature of water.Hence, water in living cells is able to accommodate large amount of heat energy to stabilise the temperate of the cells.

What is one benefit of cutting off the unopened flower buds after cross-pollination the open flowers in Wisconsin Fast Plants
Answer:
Plants will no longer use the resources to produce flowers but will convert those resources to produce seeds
Explanation:
Wisconsin Fast Plants are variety of Brassica rapa that was developed in order to improve the ability of cruciferous crops to resist to diseases.
After cross pollination( transfer of pollen from another to stigma of two different plants), using cut method, it will be difficult to close the flower bud that was cut, the resources or nutrients that will be needed to produce another flower will be use to produce seeds because the flower bud cannot be close and the bud are exposed as new flowers.

In DNA , what base pairs with cytosine? adenine guanine cytosine thymine
Answer:
guanine
Explanation:
IN DNA guanine make a base pair with cytosine and thymine make a base pair with adenine
In DNA, cytosine binds with guanine in the opposite strand. Therefore, option "B" is correct.
What is nucleotide base pairing?There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases. Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.
DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.
Therefore, nucleotides are the functional units of DNA.

The city of Los Angeles wants to know if there is a connection between physical fitness and air pollution. Fifty volunteers from the mayor’s office agree to be tested. First, they are asked to ride a stationary bike for 1 hour in a pollution-free air chamber. A week later, the 50 volunteers return and are again asked to ride a stationary bike for 1 hour in a chamber filled with air pollutants common to Los Angeles. Their heart rates are monitored throughout the 1 hour bike rides. Name the control group Name the experimental group Name the independent variable Name the dependent variable
Answer:
Control group: volunteer stationary bike riders in a pollution-free chamber
Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles
Independent variable: exposure to air pollution
Dependent variable: The heart rates (physical fitness) of the volunteer riders.
Explanation:
In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.
N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).
In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).
The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.
