Some individuals can develop kidney failure after consuming fava beans. What is the biochemical rationale for this observation?A. A deficiency of glucose-6-phosphatase that resulted in failure to synthesize essential red cell membrane proteins.B. A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.C. A deficiency of transketolase that resulted in the failure to provide ribose for the DNA and RNA needed to repair red cells.D. A deficiency of transaldolase that resulted in the failure to maintain glycolysis in the red cells. E. A deficiency of sedoheptulose that resulted in the failure to maintain the integrity of the red cells.
The correct answer to the question is option B
A deficiency of glucose-6-phosphate dehydrogenase that resulted in failure to maintain glutathione in a state that prevents destructive lysis of the red blood cell.
The deficiency of Glucose 6 phosphate dehydrogenase is a genetic disorder,when certain foods are consumed,the deficiency symptom to the enzyme is triggered and one of such food is Fava beans.
in Fava beans, Vicine is found, and this Vicine is an alkaloid glycoside.
Vicine is an oxidant,and it is toxic by causing disease favisim in individuals.The individual being affected are the ones that have hereditary loss of the Glucose 6 phosphate dehydrogenase enzyme.
But favisim only occurs when Fava beans is ingested fresh, that is without cooking it.
Following this,there is the development of acute intravascular hemolysis within 4-24hours after the ingestion of the Fava beans,there might also be a fall in the hemoglobin content of the blood and this may result in fatal condition.
But in cases that are acute, that is case of hemolysis, blood transfusion is vital and also in the case is kidney failure, dialysis must be done.
The reason why blood transfusion is very necessary is because the blood transfused may not have red blood cells that are deficient of Glucose 6 phosphate dehydrogenase,also the cells can have normal lifespan in the blood circulation of the recipient.
This Glucose 6 phosphate dehydrogenase is vital because it is a metabolic enzyme of Pentose phosphate pathway and it is also important for the metabolism of red blood cells.It also gives red blood cells protection from oxygen species that are harmful and reactive.
Option A is a metabolic disease that is
inherited which results in accumulation of glycogen and fat in liver.
Option C is as a result of deficiency in thiamine and malnutrition.
Option D is as a result of mutation in transaldolase gene.
Option E is as a result of genetic mutation.

B. Aerobic bacteria
C. Anaerobic bacteria
D. Chloroplasts
Answer:
d is your answer
Explanation:
Ancestors of Mitochondria were aerobic bacteria, according to endosymbiotic theory.
What is endosymbiotic theory ?According to Lynn Margulis' endosymbiotic theory, mitochondria in eukaryotes are thought to have originated via an endosymbiotic connection with purple photosynthetic bacteria around 1.5 109 years ago. The endosymbiont, which had been captured, was subsequently transformed into a useful organelle bound by two membranes. Supporting data for the endosymbiont theory.
Prokaryotic cells and mitochondria are the same size. The DNA found in mitochondria is structurally identical to bacterial DNA. Similar to bacteria, mitochondria are self-replicating cells divide by binary fission Two membranes enclose mitochondria, and the inner membrane is structurally very similar to that of bacteria.
Therefore, aerobic bacteria are the ancestors of mitochondria.

If a cell in G1 has 20 chromosomes, then at the end of meiosis I there will be _________ chromosomes in each daughter cell, and __________ sister chromatids in each daughter cell.
Answer:
10 chromosomes
20 chromatids
Explanation:
Meiosis is the process by which sexually reproducing organisms produce gametes for sexual reproduction. Meiosis, which reduces the chromosomal number of the parent cell by half, occurs in two stages namely: meiosis I and meiosis II.
Meiosis I is where the actual reduction in chromosomal number takes place because homologous chromosomes are separated in this stage. For example, a cell in G1 that has 20 chromosomes will have 10 chromosomes in each daughter cell at the end of meiosis I.
Since, DNA replication occurs in the S-phase, sister chromatids are formed for each chromosome. Hence, there would be 20 sister chromatids joined together by a centromere at the end of meiosis I.

Consider the food chain grasshopper mouse snakes hawks. If snakes go extinct what will happen to the food chain
Answer:
This can actually cause a major problem if the number of grasshoppers were to increase out of control. They eat plants and the number of plants,which are the basis of the food chain, could severely decrease which would impact all of the levels operating above this trophic level.
Answer:
Lack of mice
Explanation:
If the grasshopper where to go extinct the mice population would decrease. Which would lead to it being harder for snakes to find food or they would begin to rely on a different food source. But the hawks would be able to find less snakes but would overall be fine.

High tide is occurring on the sides of the Earth that are_______.
A. -experiencing sunrise and sunset.
B. -closest to and farthest from the Sun.
C. -halfway between the Sun and the Moon.
D. -closest to and farthest from the Moon.
High tide is occurring on the sides of the Earth that are closest to and farthest from the Moon. The correct option is D.
What is high tide?When the sea or a river reaches its greatest level and moves the farthest up the beach or the bank, it is said to be at high tide.
The gravitational forces that try to pull the water away from the moon are resisted by the water that is travelling away from the moon.
On the far side of the Earth, where the moon's gravitational pull is weaker, inertia triumphs, the ocean swells, and high tide happens.
The rise and fall of the sea's surface on a regular basis is what tides, which start in the oceans, appear as as they move toward the coastlines.
High tide is when the wave's highest portion, or crest, reaches a specific area; low tide is when the wave's lowest portion, or trough, happens.
Thus, the correct option is D.

What are some of the functions of vascular tissue in seedless plants? (Choose all that apply)
provides structural support that allows some lycophytes to grow taller
transports water and minerals
transports food
produces food through photosynthesis
Answer:
Explanation:
Xylem transports and stores water and water-soluble nutrients in vascular plants.
Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
Vascular tissues can provide support to the plants and also help in the transport of water, mineral and food. So, the correct options are A, B and C.
What is vascular tissue?Vascular tissues mainly perform the function of supplying all the parts of the plant with water, minerals and food. there are two kinds of vascular tissues - xylem and phloem.
Xylem is the water-conducting vascular tissue. It conducts water from the roots of the plant to various other parts. In the xylem, the movement of water is unidirectional, which means it only conducts water from bottom to top and sometimes sideways
Phloem is the food-conducting vascular tissue of plants. It conducts water from leaves to other parts of the plant. In phloem, the movement of water is bidirectional, which means it conducts water from both directions. Xylem and phloem lie next to each other in a bundle called a vascular bundle.
Lycophytes are a group of seedless vascular plants which have a unique arrangement of their vascular tissues. In these plants, the lycophytes support the growth of plants.
Therefore, the correct options are A, B and C.
