Which of the following is the best explanation of the physiological reaction to the length of daylight hours often referred to as photoperiodism? Group of answer choices Plants will only flower during long day periods when the day length exceeds their necessary photoperiod. Plants are able to respond to photoperiodism, but animals are not. Migration is triggered by temperature change and not by photoperiodism. Hibernation is often triggered by photoperiodism.
Answers
Answer:
A. Plants will only flower during long day periods when the day length exceeds their necessary photoperiod
Explanation:
Photoperiodism is a phenomenon that refers to the response of an organism to the length of day. This phenomenon causes a physiological change in the organisms involved (plants or animals). However, the best studied example of change caused by photoperiodism is that of FLOWERING IN PLANTS.
Different plants flower at different times in response to the day length. Certain plants called LONG DAY PLANTS e.g. spinach and potato etc only flower when the length of day exceeds their photoperiod (threshold), which is usually 12 hours. These plants require very short periods of darkness to flower.
Hence, according to the question, FLOWERING response in plants is the best explanation to describe photoperiodism.

Explanation:
Yes, both ferns and flowering plants produce spores in their life cycles. In fern plant, it produce spores on the underside of the leaves whereas in flowering plant, there are two types of spores such as microspores and megaspores. Both ferns and flowering plants have gametophyte as part of their life cycle. Flowering plants produce pollen grains whereas non-flowering plants produce spores to continue their generation.

Hope this helps .
Water located in wells underground is ground water. Therefore, the correct option is option C.
Water that is found below the earth's surface in cracks in rocks and the crevices between soil particles is known as groundwater. It is essential for maintaining ecosystems on our planet and supporting human activities. Groundwater is created and made available by precipitation and surface water that seeps into the ground. It gathers in subterranean aquifers, which are enormous water reservoirs contained in permeable rocks or sediments. The thickness and depth of these aquifers vary. Groundwater supply is influenced by elements like rainfall, geology, and human use. Groundwater is an important resource since it is necessary for a variety of purposes. It provides over half of the world's population with their main supply of drinking water.
Therefore, the correct option is option C.

Under semiconservative model of DNA replication, after THREE rounds of replication, how many bands of DNA would you see and which band would contain more DNA molecules
Answers
Answer:
The correct answer would be - two bands ( one intermediate, and one light)- the light band contains more DNA molecules.
Explanation:
After the switching to the lighter isotope by the second round of replication where light strands are used as template strands, produces the light band of 14N.
After three rounds of semiconservative replication, where template strand contains both heavy and new formed light bands or nitrogen and produces so in a Density gradient, there will be 2 bands one light band and the other intermediate band.

Explanation:
why can the plant grow new parts but we cannot?
Answers
Answer: because, humans can't/don't regenerate in the same way
Explanation:
Plants excel in regenerating new parts due to factors like meristematic tissues, totipotency, indeterminate growth, and unique genetic traits. These enable continuous cell division, organ regeneration, and lifelong growth, while human regenerative abilities are more limited and specialized.
Plants have the remarkable ability to grow new parts due to their unique characteristics and physiological processes. While humans and other animals also have the ability to regenerate certain tissues and organs. Here are a few reasons why plants can grow new parts more effectively:
Meristematic Tissues: Plants have specialized regions called meristems that contain undifferentiated cells capable of continuous division and differentiation. These meristematic tissues are found in areas such as the tips of roots and shoots, allowing for continuous growth and regeneration. In contrast, humans have limited areas of active cell division, such as the bone marrow and the skin's basal layer, which restricts our regenerative capacity.
Totipotency: Plant cells have a higher degree of totipotency, meaning they have the potential to differentiate into various cell types and give rise to a whole plant. This property allows plants to regenerate entire organs, such as roots, stems, leaves, and even whole plants from small tissue pieces. In humans, cell differentiation is more specialized and limited, making it challenging to regenerate complete organs.
Indeterminate Growth: Most plants exhibit indeterminate growth, meaning they can grow throughout their lifespan. This continuous growth allows plants to replace damaged or lost parts by generating new tissues and organs. In contrast, humans and animals typically have determinate growth, where growth ceases or significantly slows down after reaching a certain size or age.
Hence, plants grow, but humans can't grow.

where they execute important functions. The polypeptide chain of these proteins must cross the lipid bilayer. This presents a problem because the peptide bond is polar in nature. It turns out that in virtually all cases where an amino acid chain crosses a lipid bilayer it does so as an alpha helix. Suggest a reason why this is the case. (5 points)
Answers
Answer:
In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.
Explanation:
A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.
The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.
Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.

What is a Complementary DNA strand?A complementary DNA strand may be defined as a type of DNA strand in which the series of the constituent molecules on one strand of the double-stranded structure is chemically similar to the sequence on the other strand.
According to Chargaff's rule, the complementary DNA strand is formed with the concept of base pairing, where Adenine is complementary to Thymine and cytosine is complementary to Guanine.
Due to this, A=T, G=C, G=C, T=A, C=G, A=T, G=C, G=C, and T=A. This matches option four given in the question.
Therefore, the correct complementary DNA strand for segment 3’ AGGTCAGGT 5’ is 5’ TCCACTCCA 3’. Thus, the correct option for this question is D.
