A cross between a plant with red flowers (R = dominant) and a plant with white flowers (r = recessive) yielded 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants? Explain.
A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.
B. The results should yield plants with red flowers and plants with white flowers in a 3:1 ratio due, so the geneotype of each parent is Rr. The number of offspring was not large enough to produce the expected results.
C. The results differ from the predicted values. Therefore, the genotypes of the parents cannot be determined.
D. The results should show a ratio of 3 plants with white flowers to 1 plant with red flowers, so the genotypes of the parent plants are RR and rr.
Answer:
A. The results are close to a 1:1 ratio of plants with red flowers to plants with white flowers. Therefore, the genotypes of the parents are Rr and rr.

An 8-mer oligopeptide has the following amino acids:
A D E E F M W Y (two Es are present)
Here is your evidence:
1. Edman degradation produces A.
2. CNBr produces a 5-mer and a 3-mer that contains W.
3. Chymotrypsin produces two dipeptides and a tetrapeptide. The tetrapeptide has a total net charge of -4 at pH 12.5.
4. Staphylococcal protease in phosphate buffer produces a tetrapeptide (4-mer), dipeptide, free D, and free W.
5. Staphylococcal protease in acetate buffer produces a pentapeptide (5-mer), dipeptide, and free W.
Put in the sequence of the 8-mer (use caps here) i.e. ABCDEFGH.
All the cells in your body need ___________ to survive
Answer:
Oxygen or Minerals or Sugars (Oxygen is the most relevant one)
Explanation:
To survive, every cell must have a constant supply of vital substances such as sugar, minerals, and oxygen, and dispose of waste products, all carried back and forth by the blood cells. Without these substances, cells would die in a very short period of time.

Explanation:
Suppose you are given an unknown solution and you need to test its pH. The pH meter is broken, and all you have is the indicator bromothymol blue to use. You add two drops of bromothymol blue to 10 mL of your unknown, and the solution turns a bright yellow. Which of the following is the best estimate of the pH of the unknown solution?
a. 8.5
b. 11.5
c. 1.5
d. 7.0
Answer: The best estimate of the pH of the unknown solution is 1.5. Option C.
Explanation:
A substance which shows different colours in acidic and basic media is called an indicator. Typical examples of common indicators includes:
--> Litmus: colour in acid ( red), colour in base (blue) and colour in neutral (purple).
--> Methyl orange: Colour in acid (red), colour in base (yellow) and colour in neutral (Orange).
--> Phenolphthalein: Colour in acid (colourless), colour in base (pink) and colour in neutral (colourless).
--> BROMOTHYMOL BLUE: Colour in acid ( yellow), colour in base (blue) and colour in neutral (green).
The indicators are themselves weak organic acids or bases and hence slightly dissociated in solution. The colour of the indicator at any given point depends on the relative proportion of the dissociated ions to the undissociated molecules since they have different colours.
From the question, since the pH meter is broken, and the pH of the unknown solution is to be determined,using an indicator instead. The best estimate of the pH of the unknown solution is 1.5. This is so because BROMOTHYMOL BLUE is blue when the pH is greater than 7.6, green when the pH is between 6-7.6, and yellow when the pH is less than 6. And pH value of 1.5 is less than 6, indicating the solution is very acidic.

Which of the following statements best explains the general process of cellular respiration?
A: Living organisms use energy from the sun and water to create food in the form of sugar.
B: Living organisms take in oxygen and water to create food in the form of sugars and energy.
C: Living organisms breakdown sugar from food to combine with oxygen making usable energy
D: Living organisms take in oxygen and release carbon dioxide through the cells thereby providing energy.
Answer:
C. Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Explanation:
Cellular respiration is about making food into energy. Since C is the only one with that aspect C can be the only answer.
The statement which best explains the general process of cellular respiration is: C: Living organisms breakdown sugar from food to combine with oxygen making usable energy.
Cellular respiration can be defined as a series of metabolic reactions which typically occur in living cells, so as to produce energy in the form of adenosine triphosphate (ATP).
Generally, high energy intermediates that can then be oxidized to make adenosine triphosphate (ATP) are created during cellular respiration.
Basically, the general process involved in cellular respiration can be represented by a single equation while using the following substances;
Glucose (Sugar).Oxygen.Carbon dioxide.Water.Adenosine triphosphate (ATP).[tex]Glucose + Oxygen ---> Carbon \;dioxide + Water + ATP[/tex]
In conclusion, all living organisms breakdown sugar or glucose from their food to combine with oxygen, so as to make usable energy during cellular respiration.

Instructions: 1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow. Write the RNA directly below the DNA strand (remember to substitute Us for Ts in RNA) 2. Use the codon table posted below (or the circular one on the first page) to determine which amino acids are assembled to make the insulin protein in both the cow and the human. Human DNA DNA CCA TAG CAC GTT ACA ACG TGA AGG AAA RNA GGU GLY Amino acid Cow DNA DNA CCA TAG CAT GTT ACA ACG CGA AGG GAC RNA Amino acid
Answer:
Please find the complete table attached as an image
Explanation:
This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).
- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.
- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.
The table has been completed and attached below. Note that in the amino acids row;
GLY means Glycine
ILE means Isoleucine
VAL means Valine
GLN means Glutamine
CYS means Cysteine
THR means Threonine
SER means Serine
PHE means Phenylalanine
ALA means Alanine
LEU means Leucine

Which of the following statements describes a way in which bacteria differ from animals and plants?
The BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.
Prokaryotic cells (i.e. bacteria and Archea) have no nuclei and lack organelles.In these cells (prokaryotic cells), the genetic material consists of a single circular chromosome localized in a region of the cytoplasm called the nucleoid.On the other hand, eukaryotic cells (e.g., plant cells and animal cells) have their genetic material delimited by a membrane-bound organelle known as the cell nucleus. Moreover, eukaryotic cells also have different types of membrane-bound organelles that carry out specialized functions in the cell (e.g., mitochondria, chloroplasts, Golgi apparatus, vacuoles, etc).In conclusion, the BEST statement that describes how bacteria differ from animals and plants is bacteria do not have membrane-bound organelles and nuclei.
