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)

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.

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.

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 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.

Why is it important that antibodies have a symmetrical quaternary structure? to enable binding to many different antigens to create a variable region to create two identical binding sites for antigens to ensure a stable structure?

Answers

Final answer:

Antibodies have a symmetrical quaternary structure that is important for several reasons. It enables binding to many different antigens, creates a variable region for different specificities of binding, and ensures a stable structure for proper immune function.

Explanation:

Antibodies have a symmetrical quaternary structure for several important reasons. One reason is to enable binding to many different antigens. The symmetrical structure allows for the creation of a variable region within the antibody, which allows for different antibodies to have different specificities of binding. Additionally, the symmetrical structure creates two identical binding sites for antigens, which increases the efficiency and effectiveness of antibody-antigen interactions. Finally, having a symmetrical structure ensures a stable antibody structure, allowing for the proper functioning of the antibody in the immune response.


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.

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.
