Answer: I want to believe the question is asking for the psychologist that linked intelligence and school success. The name of the psychologist is Alfred Binet.
Explanation: Alfred Binet was a French psychologist alongside Theodore Simon developed a test (Binet-Simon intelligence scale) to measure the intellectual skills of French schoolchildren in 1904. Binet equated intelligence with common sense and he defined it as the faculty of adapting to a particular situation. The Binet-Simon test focused on memory and attention and it was developed in other to help identify French schoolchildren with learning disabilities.
The test was later revised by psychologist Lewis Terman and became known as the Stanford-Binet

Which of the following is a principle of the fluid mosaic model of cell membrane structure? a. Phospholipids consist of a polar head and a nonpolar tail made of three fatty acid chains. b. The lipid bilayer is a solid at body temperature, thus protecting the cell. c. All proteins associated with the cell membrane are contained in a fluid layer on the outside of the cell. d. Phospholipids form a bilayer that is largely impermeable to water-soluble molecules.
The correct principle of the fluid mosaic model of cell membrane structure is that phospholipids form a bilayer which is largely impermeable to water-soluble molecules. The model emphasizes the dynamic, flexible, and varied nature of the cell membrane structure.
Explanation:The
fluid mosaic model
of cell membrane structure is a principal concept in biology. It characterizes the cell membrane as a dynamic, flexible structure that resembles a 'fluid' because of its ability to shift and change shape and position. Its 'mosaic' nature is due to the variety of molecules, such as proteins and phospholipids, embedded within it. In this context, option
d. Phospholipids form a bilayer that is largely impermeable to water-soluble molecules
is the correct principle of the fluid mosaic model. Phospholipids indeed consist of a polar (hydrophilic) head and a nonpolar (hydrophobic) tail, thus forming a lipid bilayer in which the hydrophilic heads face outwards and the hydrophobic tails face inwards. This structure is what makes the cell membrane largely impermeable to water-soluble molecules.

A geneticist isolates a gene for a specific trait under study She also isolates the corresponding mRNA Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence. Did the geneticist isolate the wrong DNA? A) yes, mRNA is made from a DNA template and should be the same length as the gene sequence B) yes, the mRNA should contain more bases than the DNA sequence because bases flanking the gene are also C) no, the final mRNA contains only exons, the introns were D) no, the mRNA was partially degraded after it was removed
Answer:
C) no, the final mRNA contains only exons, the introns were removed
Explanation:
Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.
RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a mature mRNA.
So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.
Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
When polluters buy, sell, and trade permits with other polluters, this is called a __________. a. polluter-pays system b. cap-and-trade emissions c. trading system subsidy d. revolving-door policy
Answer:
Option B
Explanation:
In the cap and trade emission policy, the government of any country fixes the total amount or quantity of pollution which it can accept as a part of essential manufacturing and other industrial activities. Based on the total quantity, it issue permits to each industry a certain amount of pollution cap which it can release in a year and in case of exceed of the given limit, the polluter will be fined.
This system allows the polluters to exchange their permit benefits among themselves by trading (inclusive of buying and selling)
Hence, option B is correct

inheritance of biological characteristics is determined by individuals units known as genes. In organisms that reproduce sexually, genes are passed from parents to their offspring. In cases in which two or more forms of the gene for a single trait exist, some forms of the gene may be dominant and others may be recessive. In most sexually reproducing organisms, each adult has two copies of each gene one from each parent. These genes are segregated from each other when gametes are formed. The alleles for different genes usually segregated independently of one another
Genes are units that determine biological characteristics of individuals, with variations known as dominant or recessive. They separate or segregate when sexually reproducing organisms reproduce, and different genes usually assort independently.
Explanation:The inheritance of biological characteristics in individuals is indeed determined by units known as genes. In sexually reproducing organisms, each parent contributes one set of genes to their offspring. These genes determine the traits or characteristics of the offspring. If a gene has more than one form, or allele, these variations can be dominant or recessive. Dominant alleles will express their trait even if only one is present. Recessive alleles will only express their trait when two copies are present. The process by which these genes are separated and passed on when organisms reproduce is called segregation. Additionally, different genes tend to assort independently, a principle known as independent assortment.

Explanation:
Considering the Mendelian traits tall (D) versus dwarf (d) and violet (W) versus white (w), consider the crosses below and determine the genotypes of the parental plants by analyzing the phenotypes of the offspring.
Answer:
Explanation:for a mendelian cross between a Talk(D) and a dwarf individual (d)
DD×dd= Dd Dd Dd Dd
The offspring will be heterozygote all loci i.e all the offspring will be tall this is because one of the parents carries a dominant gene for tallness and the other parent carries a recessive gene for tallness.
This may not follow for the progeny's offspring as segregation will occur at the 2nd filial generation.
The same principle applies for violet and white, progeny will be heterozygous at all loci i.e violet color

Bacillus anthraciscauses the deadly disease anthrax. Organisms of the genus Bacillus may form endospores. This bacterium would be suitable for biological warfare because endospores __________.
Answer: Resistant to high temperatures, UV light, and desiccation
Explanation:
This bacterium would be suitable for biological warfare because endospores are resistant to high temperatures, ultraviolet light, and desiccation. An endospore is a dormant, tough, non-reproductive structure produced by a small number of bacteria from the Firmicute family. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress.They are therefore resistant to ultraviolet and gamma radiation, desiccation, lysozyme, temperature, starvation, and chemical disinfectants. Endospores are commonly found in soil and water, where they may survive for long periods of time.
Which of the following statements is an accurate combination of postulates 3 and 4 of natural selection? a. Individuals experience uniform success in their ability to survive or reproduce. b. Individuals experience no success in their ability to survive or reproduce. c. Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits. d. Individuals experience unlimited success in their ability to survive or reproduce.
Answer:
c. Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits.
Explanation:
Natural selection works on a population when genetic variations are present in its members. Some genetic traits make the organisms better adapted to the prevailing surroundings. These individuals survive more and reproduce more successfully due to the presence of specific genetic traits. Over the generations, the proportion of the beneficial genetic trait increases due to the increased reproductive success of these individuals. This is called natural selection. On the other hand, the individuals that lack these traits survive and reproduce less.
The statements which is an accurate combination of postulates 3 and 4 of natural selection is C. Individuals experience differential success in their ability to survive or reproduce due to differences in certain traits.
Postulates 3 and 4 of natural selection indicate that offspring with favorable traits are more likely to survive and reproduce, leading to a greater proportion of these individuals in subsequent generations.
Natural selection operates on the principle that individuals with advantageous traits have a higher likelihood of surviving to adulthood and producing more offspring, which further spreads these beneficial traits throughout the population.
For example, if a population of beetles has variations in color, and the darker beetles are less visible to predators, these beetles will survive longer and have more progeny. Over time, the population will have more dark-colored beetles as this trait offers a survival advantage.
Prior to the elucidation of the genetic code, prominent scientists, including Francis Crick, had predicted that each mRNA codon, coding for one of the 20 amino acids, needed to be at least three nucleotides long. Why is it not possible for codons to be any shorter?
Answer:
The genetic code may be defined as the triplet code of the nucleotides that codes for the particular amino acids. This genetic code is heritable in nature and mutation is these code can cause disease.
The codons cannot be shorter because the least three nucleotides only allows the combination of the 64 possible that contain 4 different nucleotides. These nucleotides are possible at the three different position within the codon.
There is still some controversy among biologists about whether Neanderthals should be placed within the samespecies as modern humans, or into a separate species of their own. Most DNA sequence data analyzed so farindicate that there was probably little or no gene flow between Neanderthals and Homo sapiens. Which speciesconcept is most applicable in this example?A) phylogeneticB) ecologicalC) morphologicalD) biological
Answer:
Option-D
Explanation:
There are many ways to define a species on the basis of the phylogeny, morphology and biological relationships.
The species according to the biological species concept are the organisms which can interbreed and produce the fertile offsprings but show reproductive isolation from other species.
In the given question, the modern humans and Neanderthals showed no gene flow that is they are not able to reproduce between them or we can say that they were reproductively isolated from each other. Therefore they can be classified according to the biological species concept.
Thus, Option-D is the correct answer.
Explain how you might be able to tell if your local weather was being affected by global warming.
The summers are more warm as the temperature has increased.
Explanation:
Global warming is caused by the increase in atmospheric or earth's temperature.
The greenhouse effect has been the major cause of global warming.
We know that the earth's temperature would have been so cold to survive, this problem is solved by greenhouse gases.
As the concentration of gases increase the earth's temperature is also increasing.
This increase in temperature of the planet is causing summers with high temperatures, also due to excessive evaporation rainfall is also lessened. The dry air is evaporating more quickly than precipitation or vice-versa sometimes. The water cycle is disturbed and rainfall is nil or flood is there.

How many degrees of freedom should be used when looking up the critical value for a chi-square analysis of the ratios of phenotypes observed among the F2 offspring versus the expected phenotypic ratio assuming independent assortment?
Answer:
3
Explanation:
The total number of degree of freedom in a chi-square analysis is given by following equation
[tex]D_f= N-1[/tex]
Where "N" represents the total number of sample or total number of classes of offspring in a cross.
For instance, in a monohybrid cross, the total number of classes of offspring in this cross is two, thus degree of freedom is one. However, in a dihybrid class the total number of classes of offspring in this cross in F1 generation is four, thus degree of freedom is three.
In F2 generation, the total number of class of offspring still remains four in number irrespective of number of individuals in each class. Thus, in F2 generation too the number of degree of freedom in chi square Analysis will remain 3
The maximum quantity of free values that are rational in the set of data is called the degree of freedom.
The number of degrees that should be used for chi-square analysis is three.
This can be explained as:
The number of degrees of freedom is given as:[tex]\text{D}_\text{f} =\text{N -1}[/tex]
In the above equation, N represents the total sample or the offspring classes in a cross.
In the case of a monohybrid cross the total offspring class is two so the degree of freedom will be:[tex]\text{D}_\text{f} =\text{2 - 1} = 1[/tex]
In the case of a dihybrid cross, the F1 generation has four numbers, therefore,[tex]\text{D}_\text{f} =\text{4 - 1} = 3[/tex]
The degree of freedom will be three.
Even in the F2 generation, the quantity of the class remains the same and hence the degree of freedom will be three.

What source of energy would plants release in catabolic reactions? Would an animal release the same kind of energy?
Answer:
Adenosine triphosphate (ATP)
Animals also release this source of energy.
Explanation:
All living organisms require energy to perform their life functions. This energy is obtained by breaking down organic molecules (usually glucose) in a catabolic reaction called CELLULAR RESPIRATION. These organic molecules store energy in their chemical bonds, this energy in a usable form by the cell (ATP) is released when organisms undergo cellular respiration (catabolism).
Plants likewise animals undergo this catabolic process and the same form of energy (ATP) is released for use via this process.

Answer and explanation:
Monophyletic species are the species whose lineage belongs to the common recent phylogenetic ancestor. As mentioned in the question, the girl has 3 species namely G, H, and K. Because there is no other criteria given, we assume that the closeness of alphabets would reflect the closeness of species. Thus, G and H are closer relative than K. Therefore, if she adds I, and J species in the list, all of them will be closer relatives and we can say that they are monophyletic now.
In the Galapagos Islands, Darwin noted that there were many physical changes that occurred over generations between the organisms in the mainland and those from the Island. How can isolation of a group result in a new species?
Answer:
Explanation:
The situation given in the question can be an example of "Divergent Evolution" which can be described as the formation of different or new species because of environmental changes or changes in the habitat.
The isolation between the organisms from the mainland and the islands over generations lead to the genetic exchange getting cut off and therefore leads to the evolution of the different species since there is no interaction between them and their environments are also different. This results in new species through adaptation over time.

Part A Nitrifying bacteria convert _____ to _____. Nitrifying bacteria convert _____ to _____. nitrogen gas ... ammonium nitrogen gas ... nitrates ammonium ... nitrites nitrates ... nitrogen gas ammonium ... nitrogen gas
Answer:
ammonium ... nitrites
Explanation:
All living organisms including plants require certain nutrients to sustain their growth. Plants get most of their nutrients from the soil that anchors them. However, some of these nutrients like nitrogen are found in a fixed state and needs to be converted to usable forms. Nitrogen is a key component of living cells as it is used to build certain structures e.g protein, DNA etc. in the cell.
Certain groups of bacteria called NITRIFYING BACTERIA which are capable of using energy from chemical compounds to form organic molecules. They are important aerobic microbes that play a significant role in Agriculture, as in the process of them obtaining nutrients, they help convert ammonium in the soil into nitrites (fixed nitrogen). Groups of nitrifying bacteria that perform this initial task include: Nitrosomonas, Nitrosococcus etc. Other nitrifying bacteria from another genus-Nitrobacter, converts the nitrite into the most usable form by plants (nitrates).
