Answer:
Both
Explanation:
Endurance deals with how long you can do something that puts a physical strain on your body and not necessarily how much strain at once. That being said both physical strength and emotional strength play a big role in this. Physical strength is needed to be able to exert yourself and accomplish the initial task in the first place. While emotional strength is also needed in order to not give up and persevere as long as possible. Without will power (emotional strength) you will give up as soon as you are given the opportunity.
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.

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
Explain the importance of feedback inhinbition to the cell
Answer:
Feedback inhibition is also necessary to prevent enzymes from breaking down too many molecules that are energy sources for the cell, such as glucose. Inhibition takes place in glycolysis, the process of breaking down the sugar glucose to produce the cell's "energy currency" molecule ATP.
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.
If you were to climb to the top of Mt. Everest (~9km above sea level), how many breaths of air would you need to take at that altitude to get the same amount of air in your lungs as you could when breathing at sea level?a. 3 b. 5 c. 7 d. 15
Answer:
The correct answer would be option a. 3
Explanation:
When lung exposed to a high altitude like Mt. Everest, it shows elevated heart rate, faster breathing due to hyperventilation so it could get enough oxygen supply to its tissues.
The oxygen level at sea level are three time more than the oxygen level at Mt. Everest as oxygen level is 30 to 33 percent of the seal level.
Thus, the correct answer is : option a. 3.

In a cross between a white‑eyed female with two X chromosomes and one Y chromosome (XwXwY) with a red‑eyed male, the majority of the males have white eyes and the majority of the females have red eyes. However, rare red‑eyed males and white‑eyed females are present as well. What is the most likely chromosomal constitution of the red‑eyed males and white‑eyed females resulting from this cross? X+XwY females and Xw males X+Y males and XwXw females XwY males and XwX+ females X+Y males and XwXwY females X+XwY males and Xw females
Answer:
The correct answer is - =X+Y males and XwXwY females
Explanation:
during meiosis, XXY females are prone particularly to X chromosome during meiosis. This nondisjunction can lead to the production of both X+Y red-eye male and XwXwY white eye females.
The red-eye male has resulted from the fertilization of X bearing sperm and Y bearing egg. The XwXwY is formed from Y bearing sperm and an egg with two chromosome fertilization.

Dr. Foster was studying the effects of zinc on the common cold. She hypothesized that zinc would shorten the duration of the common cold. She conducted a study in which patients suffering from a cold were given daily doses of either zinc or a placebo and the amount of time it took for them to feel better was measured. whats the independent variable: whats the dependent variable: whats the constant variable: whats the control group: whats the experimental group:
Answer:
Independent variable: Zinc doses Dependent variable: The duration of the cold. Control group: patients who received the placebo. Experimental group: Patients who received the dose of zinc.Explanation:
The independent variable is one that does not need to be influenced by anything to be measured. In addition, this variable influences the result of the experiment. In the above experiment, we can see that Dr. Foster is analyzing the influence of zinc doses on the duration of colds, with that we can conclude that the zinc doses (which influence a result) are the independent variables.
The dependent variable is one that needs an influence to be measured. This influence is the independent variable, which influences a result within the dependent variable. As we can see in the above experiment, the duration of the cold is influenced by the zinc dozen, therefore, the duration of the cold is the dependent variable.
The experimental group is the group that receives the element that is being tested in the experiment. The experiment is testing zinc doses, so the group of patients who received the zinc doses is the experimental group.
The control group is the group that did not receive the element that is being tested in the experiment. The group that did not receive the zinc doses is the control group.
What is the most likely cause of a disorder if both monozygotic and dizygotic twins show a high concordance rate?
Answer:
The options are
A. Recessive genes
B. Dominant genes
C. Different environmental experiences
D. Shared environmental experiences
The answer is D. Shared environmental experiences
Explanation:
The most likely cause of a disorder if both monozygotic and dizygotic twins show a high concordance rate is shared environmental experiences.
This is because twins usually have a very high degree of concordance rate i.e they have similar genetic traits and characteristics as a result of factors such as Recessive and Dominant genes. The disorder or abnormality which would support this is them having shared environmental experiences which will make them have it in common unlike different environmental experiences which will aid variation.

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 is the maxium temperature reached when you combine 25 grams of zinc with hydrochloric acid?
Answer:
The approximate value for the maximum temperature reached during this reaction will be 87.1 °C (option E).
Explanation:
Zinc is a reactive metal so it will strongly react with the hydrochloric acid, which also is a strong acid and so it is highly reactive too. This will result in an exothermic reaction (one where heat is given off to the surrounding).
The products of this reaction will be hydrogen gas and aqueous zinc chloride (replacement reaction).
Which of the following polypeptides is most likely to form an α-helix explain your answer.(a) CRAGNRKIVLETY (b) SEDNFGAPKSILW (c) QKASVEMAVRNSG
Answer:
(c) QKASVEMAVRNSG
Explanation:
The alpha helix is a protein arrangement tightly packed, thereby the peptide will form a rod. The option (c) is expected to form an alpha helix because it contains three amino acids charged which are aligned on the face of the helix, 1-two residues positively charged: Lysine (K) and Arginine (R), and 2-one residue negatively charged: Glutamic Acid (E).
The following polypeptides are most likely to form an α-helix explain your answer - (c) QKASVEMAVRNSG
Destabilization of α-helicesThe formation of alpha-helix required correct steric configuration. Amino acids with R-groups are too large like tryptophan, and tyrosine or too small glycine destabilize α-helices.
Proline also destabilizes α-helices has irregular geometry and causes steric hindrance because its R-group bonds back to the nitrogen of the amide group.
Option(A) CRAGNRKIVLETY
There is Glycine in this sequence, so it can not form an alpha helix.
Option (B): SEDNFGAPKSILW
The presence of glycine and proline causes not to form an alpha helix.
Option (C): QKSVEMAVRNSG
Glycine is present but still, it is most likely to form an alpha helix as glycine is the end of the sequence.

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.
