2. b. gluconeogenesis
3. d. neither
4. b. gluconeogenesis
5. a. glycolysis
6. c. both
7. a. glycolysis
8. d. neither
Explanation:
Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.
Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.
Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.
Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.
Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.
Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.

why is this technique Punnett squares used to calculate the probability of genotypes and phenotypes of one child. In other words, why is it inappropriate to say "Two out of four of their children will have brown hair?
I don’t understand this help meeee
Answer:
A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes. A Punnett square can be used to determine a missing genotype based on the other genotypes involved in a cross. It is inappropriate to say "Two out of four of their children will have brown hair because the genes could are not always going to give you what you think you are going to get. Using punnett squares just predicts the outcome, but doesn't necessarily know 100%

1. What effect does air pressure have on wind movement?
2. What happens to the density of air as it is heated?
3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer:
1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds
2. When the heat of the air increases the density of the air decreases.
3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.
Explanation:
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.

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.

However, tissue culture is derived from already differentiated cells. These cells are already determined and can only produce cell type of that plant from which they were derived.
Gene therapy is a method of using genetic material to treat or prevent certain diseases. A common method researchers have found to accomplish this is with vectors. Vectors are essentially vehicles designed to deliver therapeutic genetic material, such as functional genes, directly to cells. A vector-valued function, also called a vector function, is a mathematical function of one or more variables whose extent is a multidimensional vector or a set of infinite-dimensional vectors.

What must be true about the number of chromosomes in each sex cell (when compared to the number of chromosomes in body cells
Answer:
The number of chromosomes in sex cell must be haploid (1n) as compared to body cell which is diploid(2n).
Explanation:
Body cells are diploid while the sex cells are haploid. We can say that sex cells contain half number of chromosomes as compared to body cells.
The number of chromosomes in each s-ex cell is half the number chromosomes in body cells.
Chromosomes:Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23. Of the 23 pairs, 22 are known as autosomes. The 23rd pair is made up of the s-ex- chromosomes, called the ‘X’ and ‘Y’ chromosome. These 46 chromosomes carry the g-enetic information that’s passed from parent to child through heredity.
