Which is true about acetylcholinesterase? which is true about acetylcholinesterase? agent that blocks ach from binding to cholinergic receptors on the motor end plate enzyme that normally breaks down ach at the motor end plate agent in nerve gas and pesticides that prevents the enzymatic breakdown of acetylcholine neurotransmitter that is secreted by somatic motor neurons at the nmj?

Answers

Acetylcholinesterase (AChE) or acetylhydrolasee is an enzyme that hydrolyzes the neurotransmitter acetylcholine. It is responsible for inactivating acetylcholine (Ach) when an electrical response of a muscle cell is turned off. Organophosphates are responsible for inhibiting AChE and thus precent inactivation of Ach.

Cody is a teenager with a history of leukemia and an enlarged spleen. today he presents with fairly significant left upper quadrant (luq) pain. on examination of this area, a rough grating noise is heard. what is this sound?

Answers

The pain in the upper left quadrant match's with the location of the spleen.

The noise heard is called a splenic rub and can be accompanied with splenic infarction (occlusion of the artery that supplies the spleen). This sound is scratchy, rough and possible to hear when Cody breathes.If he holds his breath, the rub stops.

N pea plants there is complete dominance for the trait of flower color. the p allele produces purple flowers and p produces white flowers. a cross of two pea plants which are both heterozygous for flower color will produce offspring with the genotypic ratio

Answers

PP-  purple homozygote
pp- white homozygote
Pp- purple hetrozygote

If these flowers cross, we obtain heterozygote offsprings with a genotype: Pp (100% of them will be like this)

Now, if those offsprings cross with each other: Pp x Pp
results:
  1/4 would be purple  homozygote -> PP
  1/4 would be white -> pp
  2/4 would be purple heterozygotes -> Pp
Genotipic ratio: 3:1 (3 are purple; 1 is white)

Groundwater _____.

A: is recharged by precipitation.

B: stays in one place and never moves.

C:is only found in areas with wet climates.

D:exists mostly as underground rivers and lakes.

Answers

Final answer:

Groundwater is primarily recharged by precipitation, moves through the subsurface, and is stored in aquifers. It is not confined to just staying in place, wet climates, or existing as underground rivers and lakes.

Explanation:

The correct answer to the question "Groundwater _____" is A: is recharged by precipitation. Groundwater occupies the zone of saturation and moves throughout the subsurface. It is replenished or recharged through processes like infiltration and seepage from surface water as well as precipitation. Contrary to some of the other options given, groundwater does not only stay in one place, nor is it only found in areas with wet climates. It is also not exclusively in the form of underground rivers and lakes but exists primarily in the pores of soil and rock formations known as aquifers. Groundwater plays a crucial role in the hydrologic cycle, contributing to the flow of streams and rivers and serving as a vital source of fresh water for various uses, including drinking and irrigation.

Suppose an enzyme that is involved in cellular respiration is assembled by a ribosome. where will this enzyme need to be transported in order to perform its function?

Answers

Needs to be transported to the mitochondria or the cytosol.


There are four stages of cellular respiration: glycolysis, pyruvate oxidation, Krebs cycle and Oxidative phosphorylation. Glycolysis takes place in the cytosol of a cell,while the pyruvate oxidation and the following steps take place  in the matrix of the mitochondria. If the enzyme is involved in cellular respiration, it need to be in one of these places.

Early elements of the cell theory followed soon after the development of hooke's light microscope. what does this relationship suggest about the evolution of the cell theory since hooke?

Answers

After development of Robert Hooke's light microscope, early elements of the cell theory were proposed. The invention of light microscope made it easy to study the structure of microscopic cell. After deciphering the cell structure with the help of a light microscope the cell theory was proposed. The invention of microscope was a big break through in the scientific world as it enabled researchers to study the microscopic structure. Later, the microscopes were modified to study the cellular organelles and prokaryotic microorganisms.
Cell theory provides the foundation for the study related to cells such as molecular biology, cell biology, etc.

A grocery store newspaper claims that apple cider and honey can cure cancer, bronchitis, acne, bad breath, heart disease, athlete's foot, asthma, the common cold, and other ailments. a shopper decides to consume apple cider and honey exclusively. what questions should the shopper have asked before adopting the apple cider and honey diet?

Answers

The shopper should first ask if this claims created by the newspaper is true and is backed up by actual facts. While apple cider and honey do have positive benefits, it is not the answer to all ailments.
Assuming that everything said was true, the shopper then must know whether or not he/she has allergies to apple cider and honey like itching, rashes, difficulty in swallowing, etc.
Lastly, the shopper should ask how much apple cider and honey should he/she take. Too much of both can lead to adverse side effects. If he/she were to consume apple cider and honey exclusively, then they should visit a doctor or a nutritionist in order to get the right amount of intake.

How do the sperm cells of nonvascular plants reach the egg cells during reproduction?


The sperm cells are blown by the wind and land on the egg cells.

The sperm cells swim to the egg cells through their watery surroundings.

The sperm cells are forcefully ejected from their capsules to hit the egg cells.

Answers

B. The sperm cells swim to the egg cells through their watery surroundings.

Sperm cells of nonvascular plants use water to swim towards the egg cells; they are motile due to flagella and attracted chemically to the eggs for fertilization. Hence, option 2 is correct.

Nonvascular plants, such as mosses and liverworts, release sperm cells that are equipped with flagella. These flagellated sperm cells are motile and can swim through the water film or droplets that are found in their moist environments. The sperm are chemically attracted to the egg cells and swim towards them to achieve fertilization. This means that for nonvascular plants, water is an essential medium for successful reproductive cycles, unlike some seed plants that use a pollen tube in a process called siphonogamy or rely on pollinators. It's important to note that in these nonvascular plants, reproduction cannot occur without water as the sperm are incapable of reaching the egg cells through wind or being forcibly ejected as they rely on swimming.

How much pesticide will each hawk take in compared to each grasshopper

Answers

Final answer:

Hawks are higher in the food chain and are therefore at greater risk of higher pesticide concentrations through biomagnification. Ecosystems with diverse predators experience better natural pest control, reducing the need for pesticides that can harm biodiversity and ecosystem health.

Explanation:

The question posed by the student suggests a focus on the bioaccumulation and biomagnification of pesticides in a food chain. Grasshoppers, which feed directly on treated plants, may ingest certain amounts of pesticides. However, hawks, being higher up in the food chain, may consume multiple grasshoppers and other prey, leading to a higher concentration of pesticides in their bodies through the process of biomagnification. Predatory birds like hawks are particularly susceptible to high levels of pesticide due to their position at the top of the food chain. Studies have shown that pesticide use not only affects pests but also harms non-target species like insects, birds, and bats, leading to a negative impact on biodiversity and ecosystem health. For example, the pesticide DDT, known for its persistence in the environment, resulted in eggshell thinning and population declines in birds of prey, such as eagles and pelicans, until its ban in 1972 in the United States.

Promoting and preserving natural predators and their habitats can enhance natural pest control, benefitting both agriculture and the environment while reducing dependency on chemical pesticides. Ecosystems with diverse natural enemies of pests demonstrate more effective pest control compared to those relying on monocultures of pest predators.

A set of flashcards on prokaryotes is being sorted into piles. which definition should not be placed in the pile for high-gc gram-positive bacteria? a. they have a higher proportion of adenine–thymine than guanine–cytosine base pairs. b. they include several medically important bacteria. c. one species that is a human pathogen arose three million years ago in east africa. d. some species reproduce by forming chains of spores at the tips of filaments. e. they develop an elaborately branched system of filaments.

Answers

A.  they have a higher proportion of adenine–thymine than guanine–cytosine base pairs.

The option A represents the complete opposite of "high-gc gram-positive bacteria". High GC content means that this bacteria have more guanine ans more cytosine than the other base pairs- adenine–thymine. This means all the other options are correct.
