You isolate a mutant that is unable to grow on minimal media. Which data would provide the strongest support for the hypothesis that this mutation occurred in the gene that codes for enzyme 2?
a. The mold can grow on rich medium plus intermediate substrate C, but not on rich medium plus intermediate substrate B.
b. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus the initial substrate.
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
d. The mold can grow on rich medium plus intermediate substrate D, but not on rich medium plus intermediate substrate C.
e. The mold can grow on minimal medium plus intermediate substrate A, but not on minimal medium plus intermediate substrate C.
Answer:
c. The mold can grow on minimal medium plus intermediate substrate B, but not on minimal medium plus intermediate substrate A.
Explanation:
Let us first diagram the pathway for a better understanding.
The normal organism produces four enzymes that convert substrates in the medium that allow it to survive, grow, and reproduce.
initial substrate ------------> A ----------------> B ----------------> C ----------------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
Any mutation on the Neurospora´s enzymes will not let the organism grow on the minimal medium because it will not be able to convert the minimal substrate into the following one, because the mutated enzyme will not accomplish its original function.
So if the mutation occurs in enzyme 1, the organism will not be able to convert the initial substrate into intermediate substrate A. And the rest of the reaction will not be possible either because of the lack of substance A.initial substrate -----X----> A -------X-----> B ------X--------> C ------X-------> AA
mutated Enzyme 1 Enzyme 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 2, the organism will not be able to convert the intermediate substrate A into intermediate substrate B. And the rest of the reaction will not be possible either because of the lack of substance B.
initial substrate ------------> A -------X--------> B -------X------> C --------X-----> AA
Enzyme 1 mutated Enz. 2 Enzyme 3 Enzyme 4
If the mutation occurs in enzyme 3, the organism will not be able to convert the intermediate substrate B into intermediate substrate C. And the last reaction will not be possible either because of the lack of substance C.
initial substrate ------------> A ----------------> B -------X--------> C -------X------> AA
Enzyme 1 Enzyme 2 mutated Enz. 3 Enzyme 4
And if the mutation occurs in enzyme 4, the organism will not be able to convert the intermediate substrate C into the essential amino acid.
initial substrate ------------> A ----------------> B ----------------> C -------X-------> AA
Enzyme 1 Enzyme 2 Enzyme 3 Mutated Enz. 4
But, if we artificially add to the medium the substrate that should be produced by the original enzyme (and that is not converted because of the mutation), then the organism will grow and survive because the other enzymes will be able to produce the essential amino acid.
So, if enzyme 2 is the only enzyme mutated, the organism will not be able to live in a medium with substrate A because the mutated enzyme will not convert the substrate A into B. There will not be B substrate in the medium, and the other enzymes will not produce the essential amino acid. So if the mutation occurs in enzyme 2, substrate A is useless to the organism because it will not survive.
But if we add the intermediate substrate B to the medium, the organism will survive. In a medium with substrate B, all the other reactions will be possible, and the organism will get the essential amino acid. The artificial addition of B substrate will replace the function of the original enzyme 2 -which is the one that converts A into B-.
Clams that are native to China are living in the San Francisco bay. How can these clams damage the bay ecosystem?
Answer:
Marine Invasive Species are animals or algae that have been translocated from their native region to California marine and estuarine waters. Invasive species are also called introduced, exotic, alien, nonindigenous or non-native.The introduction of NIS can cause harm to the ecosystem by displacing native species, becoming a human health dangerby introducing new diseases, or cause economic havoc on commercial, agricultural, or recreational activities by clogging waterways, and impacting navigation and recreation.
A prime example of the harm an invasive species can cause is Caulerpa taxifolia, also known as Killer Algae, a strain of green seaweed believed to be released from an aquarium directly into a water body or through a storm drain. The Killer Algae forms a dense carpet on any surface including rock, sand, and mud displacing native plants and animals, disrupts the natural food chain, and seriously impacting recreational and commercial fisheries.
Although Caulerpa was successfully eradicated from California marine waters, few eradications have been attempted due to perceived challenges and high cost (over $7M was expended in the case of Caulerpa).
Number of Invasive Species Statewide
The map below shows that all major harbor areas and Bays in California have received significant NIS introductions. San Francisco Bay has the highest number of non-native species, followed by the Ports of Los Angeles/Long Beach. San Francisco Bay is a hotspot for invasions because it has high recreational boating and commercial shipping traffic, a history of oyster culture, and is adjacent to a highly urbanized area. Our research found that San Francisco Bay is a hub for the spread of NIS to the rest of the West Coast.

Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because:
A. Phosphorolysis reactions cleave bonds with phosphate instead of water.
B. Phosphorylase is a better enzyme than hexokinase
C. Phosphorylase produces a glucose phosphate without spending an ATP to do it
D. All of these
Answer:
A
Explanation:
The answer is a Because Phosphorolysis reactions cleave bonds with phosphate instead of water (: just trust me
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because phosphorolysis reactions cleave bonds with phosphate instead of water. The correct option is A.
What is glycolysis?Through a sequence of processes known as glycolysis, glucose is divided into two pyruvate molecules, each of which has three carbons.
The metabolic process that changes glucose into pyruvate is known as glycolysis.
The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.
In contrast to phosphorolysis reactions, which cleave bonds with phosphate rather than water, glycolysis can be thought of as having a larger energy yield because it begins with glycogen rather than glucose.
Not producing adenosine 5′-triphosphate is not the primary goal of glycolysis; rather, it is to produce pyruvate for the trichloroacetic acid (TCA) cycle.
By boosting the ratio of NADH to NAD+, the glycolytic synthesis of pyruvate lowers the cytosol.
Thus, the correct option is A.

Look at the speedometer at the top. What do you notice about the speed when the skater goes from a height of 6m down to 0m and back up to 6m?
Answer:
First increases then decreases.
Explanation:
The speed of skater tends to increases when it moves from high elevation of 6 m to the low height area due to sloppy region while on the other hand, when the skater moves again from 0 m or from the ground level to 6 m height its speed decreases when reaches to the highest point. First the speed of the skater increases due to moving in the direction of gravity while on other hand, the speed of the skater decreases due to movement of skater against the gravity of earth.

How do changes to genes affect the traits of an organism
Changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.
What is the significance of the genes or the traits?Changes in the genes can affect humans in several ways, such as through genetic mutations that result in changes to the regulation of gene expression and result in the addition or loss of entire genes from the organism. Not all of the genetic mutations lead to expressiable changes, but they may change the protein sequence by changing the polypeptide sequence.
Hence, changes to genes affect the traits of an organism, as genes have the capability to regulate the organism's function, and the genes can regulate the expression of proteins, which regulate the organism's phenotypic and genotypic expression.

Many closely related species of ducks have different courtship dances that are performed to solidify a pair-bond. If you were to cross individuals from each of these species what would you expect to see in the hybrid offspring if behaviors related to pair-bond formation were completely due to genetics?
Answer:
I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.
Explanation:
The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.
Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.

A. translation
B. cellular respiration
C. active transport of ions
D. replication of chromosomes
Answer:
The correct answer is - D. replication of chromosomes.
Explanation:
During every cell division, either meiosis or mitotic the chromosomal DNA present in the nucleus is needed to be duplicated and the process that involves the duplication of this chromosomal DNA is known as replication of chromosome which takes place during the interphase of the cell division.
All other processes mentioned in the options are not involved or directly not involved in the processes. Translation involves the mRNA in the cytoplasm to produce amino acids with the help of ribosomes. Cellular respiration involves mitochondria and does not require DNA in the process.

In corgis, a breed of dog, short tails are completely dominant to long tails. If two long-tailed corgis have puppies, what is the percent chance of having a puppy with a short tail?
Answer:
0%
Explanation:
This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).
According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:
All ss (long-tailed) offsprings/puppies.
Based on the question asked, 0% or none of the puppies produced will have a short tail.
