the marine animals affected by the bloom do not eat algae. How could domoic acid have poisoned these organism?
Answer:
Domoic acid is a kainic acid-type neurotoxin that causes amnesic shellfish poisoning. It is produced by algae and accumulates in shellfish, sardines, and anchovies. When sea lions, otters, cetaceans, humans, and other predators eat contaminated animals, poisoning may result.
Explanation:
Blooms of algae affect ALL TROPHIC levels because domoic acid is a neurotoxin that accumulates in different species (e.g., shellfish, sardines, anchovies, etc) which are eaten by higher consumers (e.g., manatees and dolphins), thereby altering the equilibrium of the food chain.
A food chain refers to the transfer of matter and energy as food from different trophic levels in an ecosystem.
The food chain is sustained by organisms called producers (.e.g., algae in a marine ecosystem), which are found at the most basal level of the chain.
The primary consumers (e.g., marine invertebrates) are organisms localized at the second trophic level. These organisms (primary consumers) eat producers.
The secondary consumers are organisms found at the third trophic level, which eat primary consumers, and so successively to all major trophic groups.
Blooms of algae alter the whole food chain because domoic acid is a poison that accumulates in the body of the organisms at all trophic levels.
In consequence, marine consumers at higher trophic levels (e.g., manatees and dolphins) are also affected by blooms of algae.
In conclusion, blooms of algae affect ALL TROPHIC levels because domoic acid is a neurotoxin that accumulates in different species (e.g., shellfish, sardines, anchovies, etc) which are eaten by higher consumers (e.g., manatees and dolphins), thereby altering the equilibrium of the food chain.

Which mutation(s) cause the product to be a non-functional protein?
a.Nonsense and Missense c.ilent and Nonsense b. Frameshift and Missense
d. Nonsense and Frameshift
Answer:
The correct answer is - option D. nonsense and frameshift.
Explanation:
If there is a change in the sequence of DNA resulting in premature stop codon mRNA during transcription is known as a nonsense mutation and result in a non-functional protein.
a frame-shift mutation takes place when at least two nucleotides are altered and there are less chances to be changed by two others coding for the same nucleotide. It leads to a non-functional protein.

a. Mitochondria has its own DNA
b. Mitochondria have their own nucleus
c. Mitochondria has it's own membrane
d. Mitochondria has its own ribosomes
Answer:
The correct answer is - option B. mitochondria have their own nucleus.
Explanation:
Endosymbiotic theory is a evolutionary theory which explains how eukaryotic cells evolved from prokaryotic organisms.
Evidences of endosymbiotic theory are:
1. Mitochondria and chloroplasts are double membrane bound cell organelles. The inner membrane probably evolved from the plasma membrane of engulfed bacterium and outer membrane from the plasma membrane or endoplasmic reticulum of the host cell.
2. Almost similar size of mitochondria and chloroplast and bacteria and their ribosomes.
3. Cristae of mitochondria resemble the folded membranes is groups of bacteria.
4. Mitochondrion and chloroplast both have circular DNA similar to those of bacterial DNA.
Are landslides considered a form of weathering, erosion, or deposition? Explain your answer.
Answer:
erosion
Explanation:
Landslides are actually a very extreme, fast-acting method of erosion: They transfer sediment down a slope and deposit it at the end of their path. The sediment a landslide deposits is known as its talus. The five agents of erosion are wind, waves, running water, glaciers and gravity.

Antibiotics can be used to kill the specific pathogenic bacterium, Mycobacterium tuberculosis, that causes tuberculosis. The appearance of antibiotic-resistant strains has made it more difficult to cure M. tuberculosis infections. These antibiotic-resistant bacteria survive and pass on the genes to their offspring, making the resistant phenotype more common in the population. DNA analysis indicates that the genes for antibiotic resistance are not normally present in bacterial chromosomal DNA. Which of the following statements best explains how the genes for antibiotic resistance can be transmitted between bacteria without the exchange of bacterial chromosomal DNA?
a. The antibiotic-resistant bacteria release a hormone that signals neighboring bacteria to become resistant.
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
c. The antibiotic-resistant bacteria are the result of bacteria that specifically modify their own chromosomal DNA to neutralize the antibiotics
d. The antibiotic alters the bacterial genome of each bacterium, which results in an antibiotic-resistant population.
Answer:
b. The genes for antibiotic resistance are located on a plasmid that can be passed to neighboring bacteria.
Explanation:
Transformation is a genetic process by which bacteria take up foreign genetic material from the surrounding environment. In consequence, this process does not involve direct cell-to-cell interaction. Transformation allows the occurrence of horizontal gene transfer (HGT) events among different bacteria capable of exchanging extrachromosomal DNA plasmids, thus increasing genetic diversity in bacteria. Many different types of bacteria can acquire foreign genes, including antibiotic resistance genes, by HGT events involving plasmids, transposable elements, bacteriophages, etc.

Two genes control color in corn snakes as follows: O- B- snakes are brown, O- bb are orange, oo B- are black, and oo bb are albino. An orange snake was mated to a black snake, and a large number of F1progeny were obtained, all of which were brown. When the F1 snakes were mated to one another, they produced 100 brown offspring, 25 orange, 22 black, and 13 albino.a. What are the genotypes of the F1 snakes
Answer:
The correct answer is - OoBb
Explanation:
As it is given that:
O- B- snakes = brown
O- bb = orange
oo B = black
oo bb = albino
And here, the cross between an orange snake and black snake which means:
P0 : ooBB × OObb
offspring of f1 would be =
F1 : OoBb
self cross of f1 offsprings
F2 : OoBb × OoBb
Gametes OB Ob oB ob
OB OOBB OOBb OoBB OoBb
Ob OOBb OObb OoBb Oobb
oB OoBB OoBb ooBB ooBb
ob OoBb Oobb ooBb oobb
here we get approximately similar as Phenotypic ratio as mention in question- 9 : 3 : 3 : 1 or 100:25:22:13
Thus, the correct answer would be: OoBb

Produces 4 haploid cells that each have 23 chromosomes. Does this happen for mitosis, meiosis, or both?
Answer:
Meiosis
Explanation:
Because it forms 4 daughter cells which are haploid (half the amount of chromosomes as parent cell )
"A cell with 26 chromosomes undergoing meiosis will have 4 daughter cells with 26 chromosomes each by the end of meiosis II. " why is this INCORRECT?
Answer:
the number of chromosomes each time gets halved
so the first division will have 13 in each daughter cell
and the second will have about 3 in each daughter cell

2. Consider a well-trained 130-pound female marathon runner, Jordan. Jordan has just loaded up on a carbohydrate meal and has the maximum amount of stored glycogen (6.8 grams of glycogen per pound of body weight). (10pts)
a. How many grams of glycogen is Jordan storing in her body? Show your calculations.
b. How many Calories does she have stored as glycogen?
c. If this same number of Calories were stored as fat, how much would it weigh?
d. Given your answers to a. and c., why do you think your body stores most of its extra energy as fat rather than glycogen?
e. Jordan will be competing in a marathon (26.2 miles). Given her above glycogen stores and the rate at which she consumes them running at marathon pace, she only has enough glycogen to last for 24 miles. What must she do in order to be able to run at the same pace beyond this?
Considering a well-trained 130-pound female marathon runner named Jordan.
The grams of glycogen Jordan is storing in her body is 884 grams.
Given that:
weight of the female marathon runner = 130 poundsmass of the glycogen = 6.8 grams / pounda.
The total mass of glycogen that Jordan is storing in the body of 130 pounds is:
= 130 pounds × 6.8 grams/pound= 884 gramsb. The amount of Calories she has stored in the body of 130 pounds is calculated as follows.
Since 1 gram is equivalent to 7.716179 kcal
∴
884 grams will be = (884 grams × 7.716179 kcal)/ 1 gram= 6821.102 kcal.c.
Fat is a class of food that the when consumed provides energy to the body. It is usually stored as fatty acid and is measured in pounds.
One pound of fat usually requires an energy of about 3500 calories to burn.
Since 1 pound of fat requires 3500 calories;The weight of the glycogen in fat will be:
= (6821.102 kcal × 1 pound of fat)/3500 kcal= 1.949 pounds of fatd.
The body stores most of its extra energy as fat rather than glycogen because the body after 8 hours of eating, body starvation starts to occur. At this stage, the stored fat is designated to supply energy to the body.
e.
Given that:
Jordan will be competing in a marathon of = 26.2 milesFrom her condition, she has enough glycogen to last for 24 miles.In order for her to be able to run at the same pace beyond the 24 miles, she needs to consume fatty food substances that can help her store additional fat that can be used to provide energy during the marathon race.
Therefore, we can conclude that we have understood the grams of glycogen that Jordan can store in her body, the conversion from grams to calories, and how Jordan can achieve the marathon of 26.2 miles.
