In order to refine and enhance their hypotheses, biologists heavily rely on the feedback provided by their peers.
Variation, inheritance, selection, and time all play a role in evolution. The natural selection mechanism of evolution is thought to be made up of these parts.
Darwin completed the Copernican Revolution by introducing biology to the concept of nature as a system of matter in motion governed by natural laws, which was his greatest contribution to science. The science of organisms' origins and adaptations was made possible by Darwin's discovery of natural selection.
In fact, it is so straightforward that it can be divided into five fundamental steps, here abbreviated as VISTA: Time, Adaptation, Selection, Variation, and Inheritance

In the absence of recombination (i.e., complete linkage), what ratio of phenotypes is expected in the progeny of the cross AB/ab x AB/ab? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. а 3 A-B-:1 aabb b 1 aaB-:2 A-B-1A-bb с 9 A-B-:3 A-bb: 3 aaB-:1 aabb d The ratio depends on the distance between genes. e The ratio depends on the interference.
The expected ratio of phenotypes in the progeny of the cross AB/ab x AB/ab in the absence of recombination is: 3 A-B- : 1 aabb. The correct answer is (а).
The cross AB/ab x AB/ab is a dihybrid cross between two heterozygous parents. In the absence of recombination, the alleles for each gene will stay together in the same combination in the offspring. Therefore, there will be only two types of gametes produced: AB and ab. The expected ratio of phenotypes in the progeny will depend on the genotype of each offspring. The possible genotypes of the offspring are AABB, AABb, AaBB, AaBb, AAbb, aaBB, aaBb, and aabb. The phenotype of each genotype is determined by the dominant allele. A- and B- are dominant over a and b, respectively.
The genotype AABB and AABb both have the dominant alleles for both genes, so they will have the same phenotype: A-B-. The genotype aaBb and aabb both have the recessive allele for both genes, so they will have the same phenotype: aabb.
The genotype AaBB and AaBb have one dominant allele and one recessive allele for each gene. Their phenotype will be determined by the dominant allele, so they will have the same phenotype: A-B-. The genotype AAbb and aaBB have one dominant allele and one recessive allele for each gene. Their phenotype will be determined by the dominant allele, so they will have the same phenotype: A-bb.

In ferns, male and female gametes are produced by antheridia and archegonia, respectively. As a result, the presence of both antheridia and archegonia shows that the fern is in its sexual or gametophyte phase of life that is non-dominant.
The life cycle of ferns alternates between two unique generations: sporophyte generation and gametophyte generation. The dominant phase is the sporophyte, which generates spores by meiosis. The zygote grows into a new sporophyte after fertilization, and the cycle continues.

Making an identical copy of a cell or tissue is called cloning whereas making an identical copy of an entire organism is Reproductive cloning.
The technique of creating a genetically identical replica of a cell or creature is known as cloning. Cloning occurs often in nature, for example, when a cell repeats itself asexually with no genetic changes or recombination.
Reproductive cloning entails implanting a cloned embryo into a natural or artificial uterus. The embryo becomes a fetus, which is subsequently carried to term. For more than 40 years, reproductive cloning operations were carried out using the embryo splitting method, in which a single early-stage two-cell embryo is physically separated into two individual cells and subsequently develops into two identical embryos.

The statement "the nervous system incorporates information acquired from internal and external stimuli and signals a response" best describes the function of the nervous system. The nervous system is responsible for coordinating and controlling all of the body's functions, including the ability to sense, think, and move.
It receives information from sensory receptors in the body and processes this information to determine an appropriate response, which is then transmitted via motor neurons to the appropriate effectors (muscles, glands, etc.) to produce an action or reaction. This process of receiving, processing, and transmitting information is fundamental to the function of the nervous system.
The other statements in the question are not entirely accurate descriptions of the function of the nervous system. For example, while the nervous system does play a role in signaling muscle contraction, it also controls gland secretion and many other functions in the body. Similarly, while the nervous system does use efferent and motor pathways to transmit signals, this is only one aspect of its overall function.

what is removed from dntps to provide the energy required for dna polymerase to catalyze dna strand elongation?
During DNA replication, the nucleotides that are incorporated into the growing DNA strand are in form of deoxyribonucleoside triphosphates (dNTPs), which provide the energy required for DNA polymerase to catalyze elongation of the DNA strand.
In order for the energy to be released, two phosphate groups must be cleaved from the dNTP molecule, leaving a single phosphate group and a deoxyribonucleoside monophosphate (dNMP). This hydrolysis reaction releases a significant amount of energy, which is harnessed by the polymerase enzyme to catalyze the formation of phosphodiester bonds that link nucleotides together into a new DNA strand. The released phosphate groups are also important because they can be used to form the high-energy bonds required for cellular processes such as ATP synthesis.

what is the ph of blood in the tissue and in the lungs and why does that difference in ph contribute to hemoglobin delivering oxygen? use the equilibrium equation in your argument.
The pH of blood in the tissues is slightly lower (around 7.35-7.45) than in the lungs (around 7.4-7.45), which is due to the production of carbon dioxide in the tissues, which reacts with water to form carbonic acid. This lower pH in the tissues causes hemoglobin to have a higher affinity for oxygen.
The equilibrium equation that describes this phenomenon is:
Hb + O2 ⇌ HbO2
At a lower pH, the equilibrium shifts towards the right, favoring the formation of HbO2 (oxygenated hemoglobin). This means that hemoglobin is more likely to bind with oxygen in the tissues, where the pH is lower, and release it in the lungs, where the pH is higher. This facilitates the delivery of oxygen to the tissues and the removal of carbon dioxide from the body
In summary, the difference in pH between blood in the tissues and in the lungs is a crucial factor in the ability of hemoglobin to efficiently deliver oxygen to the body's cells.

Eukaryotic DNA is replicated in a timely, synchronous fashion through the coordinated activity of multiple replication origins and replication forks.
During DNA replication, the double-stranded DNA molecule is unwound and separated into two single strands, each of which serves as a template for the synthesis of a new complementary strand. In eukaryotes, DNA replication is initiated at multiple replication origins located throughout the genome, which helps to ensure that the entire genome is replicated in a timely and synchronous fashion.
