What enzyme deficiency in RBC leads to hemolytic anemia due to oxidative stress? ​

Answers

In some cases, massive destruction of red blood cells caused death. This drug-induced hemolytic anemia was shown 30 years later to be caused by a deficiency of glucose 6-phosphate dehydrogenase, the enzyme catalyzing the first step in the oxidative branch of the pentose phosphate pathway.

Utility companies use _ per month, to determine how much energy is being used.

What goes in the blank ?

Answers

Answer:

Kilowatt-hour

Explanation:

Energy refers to the amount or quantity of power which is being consumed by an individual, group of people or organization over a specific period of time. As the consumers continue to use energy, they're being charged or made to pay a utility fee regularly for their amount of consumption, which is usually calculated hourly (kilowatts hour or kwh).

Hence, power utility companies use kilowatt-hour (KWh) per month, to determine how much energy is being used.

Which describes a similarity between abiotic and biotic factors?

Answers

Answer: They are both necessary for organisms to survive.

Briefly explain the nature of scientific inquiry. Include discussion of the role that evidence and falsifiability play in the process. Is this a strength or a weakness of the scientific mode of
thinking?

Answers

Answer:

Science is a process that involves proof and error. Scientific hypotheses are used to find evidence supporting scientific statements, but new evidence can be used to reject previously accepted ones in order to get closer to the truth.

Explanation:

Scientific inquiries refer to the processes by which scientists study phenomena of the natural world and propose alternative explanations (hypotheses) useful for understanding such mechanisms. When hypotheses are supported by many evidence and studies from different sources, scientific theories associated with these hypotheses become accepted by the scientific community. In science, a scientific statement may become falsifiable when it is contradicted by new lines of evidence and/or new observations.

In plant and animal adaptations, form follows function. True or false?

Answers

Answer:

FALSE

Explanation:

In plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.

Adaptation

Living beings tend to have adaptations according to the environment in which they live. Plants in hot and dry climates generally have their leaves reduced, or even modified into thorns, as a way of reducing the contact surface and thus avoiding transpiration.

Whit this information, we can conclude that in plant and animal adaptations, form follows function. it is true because all forms of organisms give adaptive advantages.

Answer:

corrosionbases7It warys of how much concentration there is over 7

EXPLANATION:

plz can i get brainliest:)

Alkali substances has a pH greater than 7 hence it follows that the lye in soap has a pH over 7.

What is corrosion?

The term corrosion has to do with the waering away of a metal surface due to the action of oxidation. Hence the term applicable is corrosion.

The bases are know to be have a bitter taste and are slippery to touch hence the correct response is bases.

Water is a neutral substance, in the pH scale, a neutral substance has a pH of 7 hence the pH of water is 7.

Sulfuric acid is an acid and acids have a pH that is below 7 hence the pH of sulfuric acid is under 7.

Given the fact that alkali substances has a pH greater than 7, it follows that the lye in soap has a pH over 7.

the blood speed in a normal segment of a horizontal artery is 0.15 m/s. An abnormal segment of the artery is narrowed by an arteriosclerotic plaque down to one fifth its normal cross sectional area. What is the difference in blood preassures between the normal and constricted segments of the artery. The density of the blood is 1060

Answers

Answer:

286.2  pa

Explanation:

Blood speed in a normal segment of a horizontal artery ( v2 ) = 0.15 m/s

Density of blood = 1060 kg/m^3

Normal sectional area = A2

constricted sectional area ( A1 )= 1/5 A2

Determine the difference in blood pressures between the normal and constricted segments

we will apply Equation of continuity     Av = constant

Δ p = 12 PV^2

     = 12 * 1060 * ( 0.15 )^2

     = 12720 * 0.0225  =  286.2  pa

In the late 1980s and early 1990s, the percentage of Icelandic children whose bacterial infections were caused by bacteria resistant to penicillin rose at an alarming rate. After public health officials initiated a campaign to reduce the use of penicillin, resistance dropped off. This observation is consistent with the hypothesis that ________.

Answers

Answer:

The correct answer would be - "bacterial populations evolve in response to the selection pressure imposed by antibiotics".

Explanation:

The given information provided in the question about the bacterial infection supports the hypothesis that the bacterial population shows the evolution in response to the selection pressure caused by the antibiotics due to the fact that bacteria increased resistance gradually with time. This resistance towards antibiotics increased the percentage of bacterially infected children in the late 1980s and early 1990s.

In this case, the population of bacteria having resistance genes is selected to evolved selected to increase their offsprings.
