Legend has it that there was a less famous geneticist in the 1800s
named Megor Grendel. He did his experiments with the cats that lived in the monastery's barn. Here are some results from one of his 16 crosses:
Cross #3 Maggie (orange) x ? (possibly Tom, or maybe Bill)
Kittens:
1. light orange female
2. dark orange male
3. black female
4. light orange female with white paws
5. black male with white paws
6. orange ? (sex undetermined; died at birth)
Answers
Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
The researcher has total control over the crosses. Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible. Pea plants may be examined for a greater series of generations than cats or other animals. Because plant genetics is not overly complicated, several traits may be investigated at the same period.As a result, the primary factors why Megor Grendel's experiments are not well-known:
The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism. Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern. Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.As a result, it is impossible to draw any conclusions from them.

The O2 gas produced during photosynthesis is derived (made) from
Answers
Answer:
water
Explanation:
All the O2 gas produced during photosynthesis comes from water.
The O2 gas produced during photosynthesis is derived from water (H2O).
During the light-dependent reactions of photosynthesis, which take place in the thylakoid membranes of chloroplasts, light energy is absorbed by chlorophyll molecules, initiating a series of electron transfer reactions.
These reactions split water molecules into oxygen (O2) and protons (H+), releasing oxygen as a byproduct.
The electrons derived from the water splitting are then used to generate energy-rich molecules like ATP and NADPH, which fuel the light-independent reactions (Calvin cycle) responsible for fixing carbon dioxide and synthesizing glucose.
Overall, photosynthesis is the process by which plants and other photosynthetic organisms convert light energy into chemical energy, releasing oxygen in the process.

Which resource is a non-renewable resources? A.fresh water B.Maple trees C.Solar Energy B.Precious metal
Answers
Answer:
Precious Metal, bc nature will not renew it and there's just a limited amount on any given planet.
Technically true for the sum of all water on the planet too, but fresh water gets renewed by cyclical processes in nature.
and solar energy (and trees for that matter) are also just renewed from our earthly perspective of space and time. stars do nuclear fusion, and this is a one-way process, single use basically.
so nothing is truly renewable, but we can't use up some things and get new supply for any given time, at least in time spans we can grasp.

g It was noted in the Experimental Pathways feature in Section 10.4 that at least two- thirds of the human genome is derived from transposable elements. The actual number could be much higher, but it is impossible to make a determination about the origin of many other sequences. Why do you suppose it is difficult to make assignments about the origin of many of the sequences in the human genome
Answers
Answer:
TEs are repetitive and mobile elements, thereby it is hard to trace their origins
Explanation:
Repetitive elements are patterns of nucleotide sequences in the DNA characterized to have multiple copies throughout the genome. DNA mini-satellite and Transposable Elements (TEs) are some examples of highly repetitive DNA. TEs are repetitive mobile elements that have the ability to jump within the genome and occupy a major part of eukaryotic genomes. For instance, there is a type of TEs called retrotransposons which mobilize through a copy-and-paste mechanism, thus increasing their number in a genome. In consequence, TEs represent highly repetitive and dynamic genomic sequences, and thereby it is hard to trace their evolutionary histories.
Describe passive and active freezing protections that could be set in place for an orchard of apples being grown in New York State and explain why they might be effective.
3 SENTENCES AT THE LEAST
Answers
Answer:
A good answer could include planting the trees on the north-facing flank of a hill (passive) and providing overhead irrigation to allow the grower to give plants an ice coating (active). Apples grown in New York face their strongest threat during bloom-time. North-facing plantings partway up a hillside delays bloom-time to later in spring, reducing the odds of the plants experiencing a hard frost. Irrigation allows the grower to take advantage of the severe overall cold that can be associated with a freeze in upstate New York by using the cold to create a protective ice layer that can preserve the blossoms.
Explanation:

Why is synthesizing proteins important?
Answers
Proteins there are complex macromolecules that perform a great number of functions in the body, some are even part of structures in the body, one example is hair or nails. Thus they are necessary for the structure, function, and regulation of tissues and organs in the body. W
The process of protein synthesis is important because our bodies need to be able to produce proteins that are essential to our health and well-being. Hormones, enzymes, and the growth of muscles cannot be made in our bodies without protein synthesis.
Protein synthesis accounts for the majority of amino acid disposal. A specific sequence of amino acids is defined by messenger RNA, which has been transcribed from a DNA template and binds to specific molecules of transfer RNA.
The adjacent amino acids form peptide bonds. As soon as the polypeptide chain is completed, the sequence of amino acids determines the subsequent folding, post-translational amino acid modifications, and protein packaging.
Transcription rate, ribosome aggregation, and modulation of peptide synthesis rate determine the rate of protein synthesis.

describe the effects on surface area of potato of cutting the potato sticks into eight pieces
Answers
The effects of cutting the potato sticks into eight pieces would increase the surface area of the potato, and having more surface area means more area for enzymes to interact with the potato so it can be cooked easily.
What is the significance of the increased surface area of the potato?When the potato is cut into eight pieces, the surface area increases, and as the surface area increases, the cooking time decreases because the enzymes are exposed and can be deactivated when exposed to heat. So vegetables are cut before cooking.
Hence, effects of cutting the potato sticks into eight pieces would increase the surface area of the potato, and having more surface area means more area for enzymes to interact with the potato so it can be cooked easily.

Two populations have been geographically isolated from each other for many generations.
Which statement is most likely correct about the two populations?
O They can still produce viable offspring with each other.
O They can't reproduce with each other.
O They look very similar to each other.
O Their gene pools are highly similar.
Answers
Answer:
The most likely correct statement about the two populations that have been geographically isolated from each other for many generations is "Their gene pools are highly dissimilar."
When populations are geographically isolated from each other, they are unable to interbreed, therefore, they evolve independently from each other. Over time, different selection pressures and mutations cause genetic differences to accumulate between the two populations. These genetic differences will become evident when the two populations are brought back together. If the genetic differences are large enough, the two populations may no longer be able to interbreed and produce viable offspring.
