A pure-breeding, tall pea plant with white flowers is crossed with a pure-breeding, short plant with red flowers. The F1 plants are tall, with red flowers. When allowed to fertilize themselves, these produce the following F2: 326 tall, red; 104 tall, white; 117 short, red; and 29 short, white. You are conducting a Chi-Square analysis and what is the null hypothesis?
Answer:
Null Hypothesis -
The observed frequency is approximately equal to the expected frequency of phenotype.
Explanation:
Pure Breeding Cross - TTww x ttWW
Genotype of offspring in F2 generation - TtWw
Null Hypothesis -
The observed frequency is approximately equal to the expected frequency of phenotype.
The chi square analysis is attached
The degree of freedom for this question is 3
The p value for X^2 estimated through chi square test is 0.5
Hence the null hypothesis is accepted.
A pea plant with purple flowers and green pods is crossed with a plant that has white flowers and yellow pods.All the offspring have purple flowers and green pods .If two of these F1 are crossed what phenotypes will be seen in the F2 generation
Answer:
in the next generation 75% of the plants will have purple flowers and 25 percent will have white flowers
Also 75% of the flowers will have green pods and 25% of the flowers will have yellow pods

2. A man has type A blood and his wife has type B blood. A physician types the blood of their four children
and finds that each of the children has a different blood type. What are the genotypes of the parents? How
would you explain that all four blood types could be represented by these four children?
Answer:
A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. If you have type AB blood, you have both A and B antigens .

Which of the following most likely happens in the cells of a person running a
marathon?
The respiration rate increases to produce more ATP.
The cell division rate increases to produce more muscle fibers
The photosynthesis rate increases to produce more sugars
The replication rate increases to produce more DNA
Answer:
The respiration rate increases to produce more ATP.
Explanation:
Running requires energy so the cells need to make more ATP through cellular respiration.
The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.

If you were to start at the base of a mountain and climb it all the way to the top, how would the climate change?
A The climate would get colder and drier as you go up the mountain.
B The climate would get warmer and wetter as you go up the mountain.
C The climate would stay the same because you are in the same climate zone.
D The climate would be similar to a tropical climate zone as you go up the mountain.
The climate would get colder and drier as we go up the mountain. So, the correct option is A.
What is the effect of altitude on the atmosphere?When altitude increases, the amount of gas molecules in the air decreases, so the air becomes less dense than air closer to sea level, which is what meteorologists and climbers mean by "thin air". Thinner air exerts less pressure than air at lower altitudes.
Most of the gas molecules in the atmosphere are pulled closer to the Earth's surface by gravity, so gas particles are denser near the surface, so with more gas particles in a given volume, there are more collisions of particles and therefore more pressure.
Thus, the climate would get colder and drier as we go up the mountain. So, the correct option is A.

5.Write observation and conclusion of each of the following activities
Answer:
Water puts pressure depends on their amount.
Explanation:
On the left side, there is less quantity of water in the tube that put less pressure on the bag present at the bottom and the bag swells slightly while on the other hand, on the right side, there is more amount of water in the tube that puts large pressure on the bag located at the bottom and as a result it swells higher than the other bag so we can conclude that more water puts more pressure and less water puts less pressure.

Letter U and letter S control the collection and release of waste from the cell.
В.
Letter T and letter R store the genetic material necessary for replication of the cell.
ОООО
C
Letter Q and letter S are responsible for creating and delivering nutrients throughout the cell.
D
Letter U and letter R are involved with the processes of transcription and translation for the cell.
Answer:
B) letter T and letter R store the genetic material necessary for replication of the cell
T-nucleus and R-mitochondria
The statement that correctly describes an interaction between organelles is : ( D ) Letter U and Letter R are involved with the processes of transcription and translation for the cell.
Letter U represents the Nucleus of the plant cell model attached while the Letter R represents the cytoplasm of the cell model.
The nucleus of a cell contains the genetic material ( DNA ) of the cell while the cytoplasm fills up the cell and is enclosed by the plasma cell membrane of the cell. Transcription involves the synthesis of RNA from a DNA template contained in the Nucleus and this process involves, The nucleus and cytoplasm of a cell.
Hence we can conclude that The statement that correctly describes an interaction between organelles is : ( D ) Letter U and Letter R are involved with the processes of transcription and translation for the cell.

Light-skinned people generally have a greater proportion of which pigment in their skin?
Keratin
Pheomelanin
Eumelanin
Carotene
Answer:
Pheomelanin
Explanation:
Dark-skinned individuals produce more melanin than those with pale skin.
Light-skinned people typically have a greater proportion of pigment in their skin Pheomelanin, Dark-skinned persons produce more melanin than those with pale skin.Thus, option "B" is correct
What is the difference between pheomelanin and eumelanin?
Eumelanin is black or brown tint and pheomelanin is red or yellow pigment.
Individual who create lots of pheomelanin tend to have lighter skin, often because of freckling.
Freckles occur when melanocytes clump together. Melanocytes are generally scattered rather evenly in the skin.
Thus, option "B" is correct, Dark-skinned individuals produce more melanin than those with pale skin.
