In a species of mice, brown fur color is dominant to white fur color. when a brown mouse is crossed with a white mouse all of their offspring have brown fur. why did none of the offspring have white fur?
Answer:
Because white fur is determined by a resessive allele. Resessive alleles are only expressed if they pair with another resessive allele.
Explanation:
The physical characteristics of the mice shown in the above question are determined by the dominance relationship between the genetic alleles. As we can see from reading the question, brown fur is a trait regulated by a dominant allele, in mice, on the other hand, white fur are a trait regulated by recessive alleles.
Dominant alleles are so named because certain genetic traits prevail over others. This is because dominant genes do not need their dominant allele pair on the chromosome, that is, they do not need to be double-dose in the genotype to manifest. However, recessive alleles are so named because to manifest their hereditary characters one must present a double dose in the genetic code.
In this way, we can define the reason that prevented the offspring, shown in the above question, from presenting white fur. Because white fur is recessive, it would require both parents to have white fur for this trait to be passed on to their offspring.
When you copy a selection of cells using drag and drop, which appears before you release the mouse button?
Final answer:
While copying cells in Excel with drag and drop, a moving dashed line border signifies the selection being copied. Releasing the mouse button pastes the content into the destination cells, with Excel's AutoFill feature updating any formula references.
Explanation:
When you copy a selection of cells using drag and drop in Excel, a border appears around the selected cells indicating the area to be copied. This border is typically represented by a moving dashed line, which persists around the selection until you release the mouse button. Once you drag the selection to the new location and release the mouse button, the selected cells' contents are copied to the destination cells. As you drag the cells to the point of destination using the fill handle, you may also see a ghost-like preview of the data that will be entered into the destination cells.
Moreover, if you're copying and pasting formulas that contain cell references, Excel's AutoFill feature will update these references relative to the destination cells. This functionality is particularly useful for maintaining the integrity of formula calculations throughout a spreadsheet. The fill handle is an essential tool for leveraging this powerful feature.

Goosebumps are caused by contractions of the
Goosebumps occur when the arrector pili muscles, tiny muscles attached to each hair follicle, contract. This is a survival mechanism inherited from our ancestors and can occur in response to emotions or cold weather.
Explanation:Goosebumps are caused by the contractions of tiny muscles at the base of each hair follicle known as arrector pili muscles. When these muscles contract, they cause the hair to stand upright, creating what we identify as goosebumps. The physiological reaction is a vestigial reflex inherited from our distant ancestors whose body hair would stand up to make them appear larger when faced with threats. In modern human, it is often associated with emotional responses such as fear, inspiration, awe, or cold weather.

Three species of lizard, labeled A, B, and C, are being studied using molecular analysis by two research colleagues in different laboratories. The mitochondrial DNA of lizards A and B are compared and are found to differ by 0.1%. The ribosomal RNA of lizards B and C are found to differ by 0.02%. They compare their findings and conclude that lizard B is more closely related to C than to A. What is the flaw in their reasoning, and how can their analysis be improved?
A. They applied different mathematical formulas for their computations. They should recalculate using the same formulas.
B. They compared different molecules which have different mutation rates. They should compare same molecule in the lizards.
C. They only made one measurement each. They should repeat their measurements to reduce the uncertainty in their results.
D. They used different equipment for analyzing the molecules since they work in different labs. They should work in the same lab.
Answer:
The most appropriate answer would be option B.
The flaw in their reasoning is that they compared different molecules in a different set of organisms.
For example, they compared the DNA of lizard A and B whereas they compared the RNA of lizard B and C.
In addition, the mutation rates of different molecules (DNA and RNA) are different and thus, comparison of DNA in one set of organism and comparison of RNA in another set cannot be used as the basis for the conclusion.
Answer:
B. They compared different molecules which have different mutation rates. They should compare same molecule in the lizards.
Explanation:
The researchers shown in the question above wish to discover the genetic relationship of three lizards based on analyzes of different molecules. The researchers evaluated the difference between DNA in lizards A and B and evaluated the difference between RNA molecules between lizards B and C, so it is not possible to detect a genetic relationship between lizards. The correct thing would be for researchers to investigate only the DNA of all lizards, or just the RNA of all lizards.

What are the animals species called that exhibit long gestation periods, give birth to relatively large offspring and maintain population numbers close to the habitat carrying capacity?
The animal species with long gestation periods, large offspring, and numbers close to habitat carrying capacity are called K-selected species. They have fewer offspring but provide extensive parental care. Their strategy contrasts with r-selected species, who produce many offspring but offer little parental care.
Explanation:The animal species that exhibit long gestation periods, give birth to relatively large offspring, and maintain population numbers close to the habitat carrying capacity are known as K-selected species. These species, including many mammals like humans, kangaroos and pandas, as well as certain plants like oak trees, have few offspring during a reproductive event but provide extensive parental care to them.
Despite being larger at birth, the offspring of these species are relatively helpless and require time and care to develop skills needed to compete for natural resources. The investment in long-term parental care exemplified by these species, however, can sometimes come at the expense of their own health.
In ecological theory, this K-selection strategy is contrasted with r-selection, wherein species produce many offspring but provide little to no parental care. The terms k-selection and r-selection refer to the ecological concepts of carrying capacity (K) and intrinsic growth rate (r) respectively.

Why ornithine is unlikely to be found in proteins in vivo mcat?
Ornithine is unlikely to be found in proteins in vivo mcat because not every amino acid found in the human body is identified by a codon in the genetic code or merged into proteins, that is Ornithine.
Ornithine is found as one of the intermediates in the urea cycle, the process of metabolism when the body excretes excess nitrogen.
C) what is the overall charge of the most abundant tripeptide species at neutral ph (ph 7.0)?
At a neutral pH of 7.0, the amino and carboxyl groups of amino acids are partially ionized.
The charge of a tripeptide relies on its amino acids and their pKa values. The tripeptide's three-letter amino acid code can be used to analyse charges at neutral pH:
Acidic amino acids like aspartic and glutamic acids are negatively charged at pH 7.0.
At pH 7.0, basic amino acids like lysine, arginine, and histidine are positively charged.
At pH 7.0, neutral-side amino acids like glycine, alanine, and leucine are uncharged.
The tripeptide's charge is the total of its amino acid charges. We require tripeptide sequence amino acid information to find the most prevalent tripeptide species at neutral pH.

The overall charge of the most abundant tripeptide species at neutral pH (pH 7.0) depends on the individual amino acids in the tripeptide and their respective charges. If the amino acids have neutral side chains, the tripeptide will have a neutral overall charge. If one or more amino acids have positively or negatively charged side chains, the tripeptide will have a positive or negative overall charge, respectively.
Explanation:The overall charge of the most abundant tripeptide species at neutral pH (pH 7.0) depends on the individual amino acids present in the tripeptide. In general, at neutral pH, amino acids can exist in different forms depending on the pH of the solution. Amino acids can either be positively charged (cationic), negatively charged (anionic), or neutral. The overall charge of the tripeptide can be determined by considering the charges of the individual amino acids and their respective pKa values.
For example, if the tripeptide consists of three amino acids with neutral side chains at neutral pH, then the overall charge of the tripeptide would be neutral. However, if one or more of the amino acids have positively or negatively charged side chains, then the overall charge of the tripeptide would be either positive or negative, respectively. It's important to note that the specific amino acids present in the tripeptide would determine the overall charge at neutral pH.
