Answer:
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+
Explanation:
Pyruvate is converted to lactate by the enzyme lactate dehydrogenase under anaerobic condition.
Conversion of pyruvate to lactate during redox reaction oxidizes NADH to NAD+ . This is because every glucose molecule that will be converted into pyruvate, two NADH molecules are produced and there is need for the NADH molecules to be oxidised back to NAD+ to ensure the continuity and maintenance of glycolysis.
How could you tell if the powder was salt sugar flour or baking soda
Answer:
Through chemical reactions.
Explanation:
You tell if an unknown powder is salt, sugar, flour or baking soda by doing tests to see how the powder would react. For an example, baking soda in vinegar would cause it to fizzle, while flour would just make the vinegar murky and cloudy. With salt and sugar, you can test if it dissolves and if it does it is sugar. If not, it is salt.

Minos, king of Crete, had made war upon Athens. He had come with a great fleet of ships and an army, and had burned the merchant vessels in the harbor, and had overrun all the country and the coast even to Megara, which lies to the west. He had laid waste the fields and gardens round about Athens, had pitched his camp close to the walls, and had sent word to the Athenian rulers that on the morrow he would march into their city with fire and sword and would slay all their young men and would pull down all their houses, even to the Temple of Athena, which stood on the great hill above the town. Then Aegeus, the king of Athens, with the twelve elders who were his helpers, went out to see King Minos and to treat with him.

If an enzyme is placed in a lower than optimal pH, its loss of activity might be due to
Answer:
denaturing of the peptide bonds
Explanation:
Enzymes are proteins that help speed up chemical reactions. However, they require specific temperatures and pH's to work optimally and produce the best outcome.
If an enzyme is placed in a lower than optimal pH, that means that there are more H+ ions, and the environment is more acidic. This influx of H+ ions can denature the peptide bonds within the enzyme, causing it to fold in a different way and be unable to carry out its normal duties. Hence, the activity of the enzyme will decrease significantly.

What characteristics of life distinguishes a fire and a flowering plant?
A sugarcane plant with yellow pollen and wavy leaves is crossed with a plant with yellow pollen and smooth leaves. Seed are collected and germinated. The following results are obtained in the progeny:
153 yellow pollen, wavy leaves
145 yellow pollen, smooth leaves
48 white pollen, wavy leaves
51 white pollen, smooth leaves
a. For each locus (trait): Assign appropriate symbols for the alleles of the genes, indicate the dominance interaction between the two alleles, and give all possible genotypes and their associated phenotypes
b. Give the genotypes of the parents of this cross.
c. Give the expected genotypic and phenotypic ratios of the progeny of this cross.
Answer:
a.
i) Y and y represent Yellow and white alleles for the pollen color gene; where Y (yellow) is dominant over y (white).
ii) W and w represent wavy and smooth alleles respectively for the leaf texture gene. W (wavy) is dominant over w (smooth).
YYWW, YyWW, YyWw, YYWw- yellow, wavy phenotype
YYww, Yyww- yellow, smooth phenotype
yyWW, yyWw- white, wavy phenotype
yyww- white, smooth phenotype
b) yellow pollen and wavy leaves (YyWw) × yellow pollen and smooth leaves (Yyww)
c) Expected genotypic and phenotypic ratio of progeny: 3:3:1:1
Explanation:
This question involves two distinct genes; one coding for pollen color and the other for leaf texture. Let Y and y represent Yellow and white alleles respectively for the pollen color gene; where Y (yellow) is dominant over y (white) while W and w represent wavy and smooth alleles respectively for the leaf texture gene; W allele (wavy) is dominant over w allele (smooth).
Next, we convert the progeny number to phenotypic ratio by dividing each number by the smallest number (48)
yellow pollen, wavy leaves= 153/48 =3.18
yellow pollen, smooth leaves= 145/48= 3.02
white pollen, wavy leaves= 48/48= 1
white pollen, smooth leaves= 51/48= 1.06
Approximately, the phenotypic ratio of the progeny is 3:3:1:1
According to the question, a parent with with yellow pollen and wavy leaves will have genotype YyWw because white pollen (w) and smooth leaf (s) was produced in the progeny. Also, the other parent with yellow pollen and smooth leaves will have genotype: Yyww. In a cross between these two parents i.e. YyWw × Yyww, the following gametes will be produced:
YyWw- YW, Yw, yW, yw
Yyww- Yw, Yw, yw, yw
Using these gametes in a punnet square (see attachment), the following 16 offsprings will be produced in a ratio 3:3:1:1
yellow pollen, wavy leaves (Y_W_) 6
yellow pollen, smooth leaves (Y_ww) 6
white pollen, wavy leaves (yyW_) 2
white pollen, smooth leaves (yyww) 2

An organism has the following genotype: AABb. What type of gametes can be produced, and in what proportions ?
Answer:
AB Ab AB Ab
AB 50 Ab 50
Explanation:
The organism can produce TWO types of gametes: AB and Ab. Supposing these genes are unlinked, the proportion of gametes will be 1/2 (50 percent of each gamete).
Meiosis is a reductional cell division where the resulting daughter cells (gametes) where chromosome number is divided into half, thereby producing haploid gametes in a diploid individual.The law of segregation (also called Mendel's First Law) indicates that during meiosis, alleles separate.In consequence, after meiosis, each gamete receives only one allele for a given trait.In conclusion, the organism can produce TWO types of gametes: AB and Ab. Supposing these genes are unlinked, the proportion of gametes will be 1/2 (50 percent of each gamete).

The correctly sequenced sections of the small intestine are: ____________, _____________, ____________.
Answer:
The correct answer is: duodenum, jejunum, ileum.
Explanation:
The small intestine is the part of the digestive tube that is mostly responsible for the absorption of nutrients that we incorporate through our diet, although part of the digestion also occurs in this segment (specifically in the duodenum).
The first segment, the duodenum, is the shortest of the three (about 25 centimeters in length) and is the one that is connected to the stomach. The duodenum receives the bile (from the liver), the pancreatic juice (from the pancreas), and the gastric chyme (from the stomach), to digest proteins and fat.
The second segment, called the jejunum, is about 2,5 meters long and its main task is to absorb the products of digestion, such as amino acids, carbohydrates, and fatty acids. This is how the nutrients reach our bloodstream and then the tissues where they are needed.
The last segment, the ileum, is the longest (about 3 meters long) and it's responsible for the absorption of vitamin B12 and bile acids. The ileum then connects to the large intestine, where water will be absorbed.

Answer:
Explanation:
:
D. when the stomata are open, CO2 can get in but water can get out
Explanation:
Stomata are openings in leaf epidermis that are small they permit the entry of carbon dioxide and also allow the exit of water vapour.
Opening and closing of stomata is regulated according to physiological needs of the leaf.
Carbondioxide that is diffuses into the leave is used for photosynthesis.
Plant regulates water loss from the stomata. during the hot and cold weather water is conserves to maintain a cool environment in plant this is done by closing of stomata.

Answer:
Caterpillars are in a semi-hibernation phase
Explanation:
During winter caterpillars dehydrate themselves and generate a cryoprotectant that flows in their circulatory system (i.e., hemolymph) to avoid water freezing, thus preventing tissue damage. For example, Pyrrharctia Isabella (Lepidoptera, Erebidae), a caterpillar common in North America, can survive 1 week at −20°C. This condition is known as 'semi-hibernation' and it ends when the first temperate days arrive.
