Final answer:

A habitat is the physical location of an organism, while a niche encompasses the organism's function within a community and its interaction with abiotic factors of the environment.

Explanation:

A habitat is the specific, physical location of an organism. Habitats can be identified at different spatial scales. A niche is the function or occupation, of a life-form within a community. An organism's niche incorporates the physical (habitat), chemical, and biological factors that maintains the health and vitality of the organism. An organism's interaction with the abiotic factors of its environment (heat and moisture) defines its niche.

Mendel's work mainly studied traits with simple, single trait inheritance patterns. Discoveries post-Mendel's times revealed more complex inheritance patterns that would have made his determinations of inheritance as difficult. Traits showing discontinuous variation, that Mendel worked with, deviate from the prevalent theory of that time that considered traits blend in offspring.

Gregor Mendel studied traits where the inheritance was straightforward in pea plants. These traits fell under a single characteristic with dominant and recessive alleles. However, several modes of inheritance that were discovered after Mendel's times deviated from this simple pattern of inheritance. These include incomplete dominance, codominance among others.

If Mendel has encountered traits with complex inheritance patterns, it would have made determining the inheritance as he did, difficult. The simple mono-hybrid crosses, which are matings between two purebred individuals that differ in one characteristic, would not have given predictable results as they did.

Further, Mendel's work went largely unnoticed because, at that time, the scientific community was incorrect in thinking that inheritance worked by blending the traits of parents, producing an intermediate phenotype in the offspring. This was so because many traits show continuous variation, a range of small differences among individuals, making the offspring seem like a 'blend' of their parents' traits. Mendel, however, worked with traits showing discontinuous variation, with the individuals showing either of the two easily distinguishable traits.

Mendel studied traits in pea plants that were easy to categorize with simple dominant-recessive patterns, making it possible to establish the basic laws of inheritance. Traits involving incomplete dominance, polygenic inheritance, or genetic linkage show more complex inheritance patterns, which would have made Mendel's work much more difficult.

Gregor Mendel discovered Mendelian inheritance by studying traits in pea plants that were controlled by a single gene with two alleles; one dominant and one recessive. This simplistic scenario allowed for straightforward observations of phenotypic patterns across generations. However, there are complex modes of inheritance that go beyond this, such as incomplete dominance, polygenic inheritance, and genetic linkage. In incomplete dominance, a heterozygous individual exhibits a phenotype that is a blend of the two homozygous phenotypes. For example, in the case of flower color, a red-flowered plant (RR) and a white-flowered plant (WW) might produce pink flowers (RW) in their offspring, unlike the clear dominant-recessive relationship observed by Mendel. Polygenic inheritance involves multiple genes contributing to a single trait, resulting in continuous variation of phenotypes, as seen in human traits like height or skin color. This complexity with multiple genes and alleles interacting would have made it challenging for Mendel to discern clear patterns of inheritance. Genetic linkage occurs when genes are located close together on the same chromosome and tend to be inherited together. This violates Mendel's law of independent assortment and would have obscured the inheritance patterns Mendel observed in his pea plants. If Mendel had encountered these complex forms of inheritance, his task of elucidating the principles of inheritance could have been much more challenging, or perhaps even impossible, with the knowledge and tools available during his time.

Answer: 1/4

Explanation:

Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.

Answer:

Explanation:

Lactose operon or lac operon  (includes lacZ, lacY and lacA genes) is found in some bacteria and the products of its genes are involved in lactose metabolism. So, this operon is active (genes are transcribed) when lactose is present and glucose is absent (or at low level). The operon is regulated by the lac repressor which acts as a lactose sensor and catabolite activator protein (CAP) which acts as a glucose sensor.

When there is lactose (in the form of allolactose) lac repressor detects it and stops being repressor. This enables transcription.

CAP detects glucose (via cAMP) and activates transcription when glucose levels are low.

Answer:

The answer is C. Hydrogen bonds between the base pairs hold the two strands of DNA together.

Explanation:

Watson and Crick proposed the double helical model of DNA. This model says that DNA exists as a double helix. It has two polynucleotide strands. Each strand consists of a sequence of nucleotides linked together by phosphodiester bonds. The backbone is formed of sugar and phosphate. The nitrogen bases are projected more or less perpendicular to the sugar phosphate backbone but face inside. The base pairing is specific. The two polynucleotide strands are held together in their helical structure by hydrogen bonding between bases in opposing strands. Adenine and thymine form two hydrogen bonds. Guanine and cytosine form three hydrogen bonds.

The two strands of DNA in the double helix are held together by hydrogen bonds between the nitrogenous base pairs, where adenine pairs with thymine and cytosine with guanine. The sugar-phosphate backbone is on the exterior, bonded by covalent bonds.

In the DNA double helix, the two strands of DNA are held together by hydrogen bonds between the nitrogenous bases of the component nucleotides. This specific bonding is referred to as complementary base pairing, where adenine pairs with thymine, forming two hydrogen bonds, and cytosine pairs with guanine, forming three hydrogen bonds. The sugar-phosphate backbone, consisting of alternating sugar and phosphate groups, forms the outside of the helix and is held together by covalent bonds, while the nitrogenous bases are stacked in the interior.

The correct answer to the student's question is: C. Hydrogen bonds between the base pairs hold the two strands of DNA together.

Answer:

Explanation:

A heterozygous individual (Ee) for earlobe attachment will produce two kinds of gametes—50% containing the dominant allele (E) and 50% containing the recessive allele (e). Earlobe attachment is an autosomal trait, with free-hanging earlobes being dominant.

Genotypes and Gamete Formation

A person with a heterozygous genotype Ee for earlobe attachment will produce two kinds of gametes: one with the dominant allele (E) and one with the recessive allele (e). Since gametes are formed through meiosis, which separates the two alleles, each gamete will contain only one allele.

The frequency of each gamete type will be 50% for the dominant allele (E) and 50% for the recessive allele (e). This is because the person has only one copy of each allele to pass on, and there is an equal chance of passing down either the dominant or the recessive allele in a single gamete.

In terms of autosomal traits, earlobe attachment is controlled by a single gene with two different alleles located on one of the 22 human autosomes. The presence of free-hanging earlobes is a dominant trait, whereas attached earlobes are recessive.

Answer:

0.5

Explanation:

According to Hardy-Weinberg equilibrium p2+2pq+q2=1 (p+q=1)

p2 is frequency of the dominant homozygous genotype

2pq is the frequency of the heterozygous genotype

q2 is the frequency of the recessive homozygous genotype

In the example above 80 chickens have bare legs (ff)-recessive homozygous which means that the frequency of that genotype is 80/240+80=0.25 (q2), frequency of the recessive allele is[tex]\sqrt{0.25}[/tex]=0.5. This means that the frequency of the dominant allele (p) is 1-0.5=0.5

So, the frequency of the heterozygous genotype (2pq) is 2*0.5*0.5=0.5

The frequency of the dominant homozygous genotype is p2=0.25

Hardy-Weinberg equilibrium referred to constant genetic variation in population from one generation to other in absence of disturbing factors. Here, heterozygous for feathered legs will be 160.

The basic requirements for Hardy-Weinberg equilibrium are no mutation, no gene flow, no selection etc.

Hardy-Weinberg equilibrium can be calculated as

Answer:

The plasma membrane is the control center of the cell.

Explanation:

The plasma membrane is a thin, porous, microscopic envelope that coats the cells of prokaryotes and eukaryotes. It is a semipermeable structure responsible for the transportation and selection of substances entering and leaving the cell. It has several functions that are critical to cell development and survival, such as receptor receptors for chemical messages from outside the cell, as well as transferring signals into the cell, acting as a selective barrier and creating compartments within the cell. .

The false statement is that the plasma membrane is the control center of the cell, as this role belongs to the nucleus. The plasma membrane provides a selective barrier, regulates chemical messaging, and also allows recognition between cells.

The false statement regarding membrane function is 'The plasma membrane is the control center of the cell.' The control center of the cell is actually the nucleus while the plasma membrane has several other roles.

The plasma membrane performs the critical function of forming a selective barrier around the cell, determining what enters and exits the cell. It is also very flexible, allowing cells like red and white blood cells to change shape when necessary. Furthermore, the plasma membrane has receptors essential for cellular communication, helping the cell respond to chemical messages and playing a role in signal transduction by transferring signals to the cell's interior. It also helps in creating compartments within the cell and carries markers for cellular recognition important for tissue and organ formation as well as immune response.

Answer:

E) reduce the number of primary producers

Explanation:

The primary producers are the ones that are the basis of any ecosystem on the planet. They have the ability to produce food for themselves, thus they are autotrophs, and they are the ones that are the food source for the primary consumers. With reduction of the primary producers the whole ecosystem will instantly feel the effects. The primary consumers will be left without food, meaning that they will start to die out. The dying out of the primary consumers will lead to dying out of the secondary consumers, and their dying out will result in the dying out of the predators, or rather the tertiary consumers. The end result will be a collapse of the ecosystem, which will then be inhabited by other organisms, first through the primary succession, and then through the secondary succession, resulting in a new and different ecosystem.

According to the equilibrium model of island biogeography, species richness would be greatest on an island that is C) large and close to a mainland.

Hope this helps you!! :)

Species richness is greatest on islands that are large and close to a mainland due to higher immigration rates and greater habitat diversity, which can support more species, option C is correct.

According to the equilibrium model of island biogeography, species richness would be greatest on an island that is large and close to a mainland. This model predicts that islands close to a mainland have higher rates of species migration due to proximity, which increases species diversity. Larger islands offer a greater availability of niches, can support larger populations, and have lower rates of species extinction compared to smaller islands. Thus, the combined effects of proximity to a source of species (mainland) and island size contribute to a higher species richness.

A) stripes of a skunk

Explanation:

The aposematic coloration is coloration that has been developed by the living organisms in order to warn the predators that they can be dangerous and harmful, thus to not attack them. Usually this type of coloration tends to stick out significantly when compared with the coloration of the other species that do not exhibit it, thus making it much more easy for the animal or plant to be recognized by the predators, which is benefiting both sides. The coloration of the skunk is a nice example of aposematic coloration. The skunk has black basis, but it has straight white stripes along its back. The two colors are contrasting, so it sticks out very easily. The predatory animals immediately notice it and just move along and do not bother the skunk because they are aware that it can pose a danger to them if they attack it.

Final answer:
