Suppose you are involved in a project studying a population of Dalea purpurea (purple prairie clover), a diploid, bee pollinated plant growing at Cayler Prairie in NW Iowa. You collect a sample from 100 individuals and assay DNA sequence variation at the apetala locus, which controls floral morphology. You find two distinct sequences: L and S. Individuals that are LL have very large petals, LS plants have medium sized petals, and SS plants have small petals. Your sample of plants yields the following observed and Hardy-Weinberg expected (HWE) genotypic counts:.Genotype: Observed Counts: HWE Counts:LL 14 9LS 32 42SS 54 49a. The population is in Hardy-Weinberg equilibrium, giving no indication of the preferences of the bees.b. LS heterozygotes are favored due to hybrid vigor.c. Bees are preferentially visiting smaller flowers resulting in a reproductive advantage for plants with smaller petals.d. LL genotype plants have a reproductive advantage due to their larger flowers.e. Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.
Answer:
Option E
Explanation:
Bees preferentially cross-pollinate flowers of the same size (like size mating with like) resulting in inbreeding with respect to genotypes at the apetala locus.
Inbreeding increases the frequency of homozygousity and deviates from the assumptions of the hardy Weinberg's principle

Which of the following are the four categories of pharmacokinetics? Diffusion, active transport, interspersing, and storage Ingestion, metabolism, interspersing, and excretion Ingestion, settling, movement, and storage Absorption, distribution, metabolism, and excretion
Answer:
Absorption, distribution, metabolism and excretion, it is for that reason that they are collectively known as ADME.
Explanation:
Pharmacokinetics can be referred to as the study of the absorption dynamics of a particular drug, the mechanisms involved in its distribution in the body, its metabolism and finally excretion. Pharmacokinetics is used to quantify the time and rate of drug absorption, thereby it also enables to calculate the temporal changes in concentration of one drug within an organism.
State the difference between sex limited trains and sex influenced traits. According to your perception which one is more Penetrance? (no more that 3 lines)
Answer: Penetrance can be defined as an extent to which a particular gene or set of gene is expressed in the phenotype.
Explanation:
Sex-limited traits are those traits that can observed in organisms belonging to a particular sex or gender. For example, barred coloring in chicken are observable only in roosters.
Sex-linked traits are traits or genes that are carried by either sex chromosomes are sex linked traits. The traits is sickle cell anemia.
Sex-linked traits is of more penetrance, because the trait will be expressed by either sex chromosome X or Y.
_________10. Which of the following groups of plants carry out light dependent and light independent reactions of photosynthesis in separate cells?
A. Plants with chlorophyll C. C3 – plants
B. CAM Plants D. C4 – plants
15 point
Answer:
D. C4 plants
Explanation:
Photosynthesis is the process by which plants and other photoautotrophs synthesize carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts.
Photosynthesis occurs in two stages:
The light-dependent reactions and
The light-independent reactions, or Calvin Cycle.
Light-dependent reactions occur in the presence of sunlight. In these reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the grana within the chloroplast.
Light-independent reactions or Calvin cycle: In these reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. There are three phases to the light-independent reactions: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.
C3 plants carry out both the light-dependent and the Calvin cycle within the choroplast organelles. They carry out the Calvin cycle by producing a three-carboncompound called 3-phosphoglyceric acid, hence the name C3.
C4 plants carry out photosynthesis in a two-stage process that first produced a four-carbon intermediate compound in the chloroplast of a thin-walled mesophyll cell. Once synthesized, the plant pumps the intermediate compound into a thick-walled bundle sheath cell, where it splits the compound into carbon dioxide and a three-carbon compound. The carbon dioxide then undergoes the Calvin cycle.
CAM (crassulacean acid metabolism) plants carry out photosynthesis by absorbing sunlight energy during the day, and then using the energy to fix carbon dioxide molecules during the night.

80%
O
C Offspring display an intermediate form of the trait.
60%
D The dominant form of the trait shows.
Answer:
The correct answer is : The dominant form of the trait shows.
Explanation:
In simple dominance, the attribute related to the prevailing or dominant allele is communicated while the character related to the latent or recessive allele is persecuted or masked. For instance –
Taking a bloom where the dominant allele attribute is red shading and the recessive allele characteristic is white shading. At the point when a posterity of this bloom is created containing one prevailing or dominant allele and one passive allele, its shade would be red simply because just the predominant allele communicates its characteristic.
Thus, the right answer is: The dominant form of the trait shows.

NUCLEIC ACIDS:
Nucleic acids are one of the four biomolecules in nature. The two nucleic acids are DNA and RNA. Nucleic acids are generally involved with the storage and coding of genetic information in living cells. DNA specifically stores genetic information in the nucleus of a cell. During transcription, DNA is transcribed into mRNA (messenger RNA) in the nucleus. This means that the information in the DNA is encoded in an RNA molecule. The mRNA functions to transport the genetic information out of nucleus into the ribosome (site of protein synthesis) where translation takes place. Therefore, the role of DNA is to move information from the nucleus to the ribosomes for protein synthesis.Learn more: https://brainly.com/question/241631?referrer=searchResults

2. Fossil fuel reserves will never be depleted.
3. Fossil fuels are easily renewed.
4. Fossil fuel use does not affect the environment.
Answer:
Option 1. Fossil fuels are cheaper than alternative forms of energy.
Explanation:
Fossil fuels are made by the natural procedure in a more extended time frame, for example, anaerobic decay of the dead living resembling plants, and creatures. These plants and creature's decayed naturally to pilled up to frame coal, or common gases or raw petroleum.
By the utilization of these fuels, the stores are constantly exhausting and as it can not be recharged it will not present in the future. Non-renewable energy sources expand the greenhouse gases in condition and influence it by increasing carbon in climate. Be that as it may, these energizes are less expensive in comparison to different fuels.

The correct answer is A. A law
Explanation:
In science, a law describes a phenomenon or event that always occurs under specific circumstances, and therefore it is constant. Due to this, laws are created based on multiple experiments or observations that lead to the same result. Also, a law only describes a phenomenon but does not explain why this occurs, which belongs to scientific theories.
The statement "traits are passed from parents to offspring independently of one another" by Mendel is a law because it describes a proven and constant phenomenon in genetics. Also, this is the result of the multiple experiments made by Mendel that showed the same result in terms of genetics.

PLEASE HELP!! In a population, the number of organisms hovers around 10 per acre. When the number goes much higher, the organisms cannot find enough food, and some don't survive. When it goes much below, they thrive and reproduce quickly. What is the limiting factor in this example? *
Answer:
food and land
Explanation:
A limiting factor is the one that limits the growth of any organism’s population. Here the population growth of an organism is limited by both availability of food and land. As the population grows, the food availability gets limited and hence most of the organism die.
But when the population reduces, the food quantity becomes surplus and thus the organisms survive.

Review the equations used to describe photosynthesis and respiration (as provided in the introduction and background section of this experiment). Why was it important to use germinated seeds without leaves for this experiment?
Answer:
1. Photosynthesis equation: 6CO2 + 6H2O + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Respiration equation : C6H12O6 + 6O2 --> 6CO2 + H2O + ATP
2. Provided that the seeds had leaves the response between the NaOH and the CO2 would be destroyed by the leaves which would change the oxygen levels in the test tube or cylinder.
Explanation:
Photosynthesis and respiration both are the essential parts of the carbon cycle in atmosphere. Photosynthesis use carbon dioxide from the atmosphere while respiration releases carbon dioxide back in to atmosphere. CO2 is the major component that helps in carbon recycle in carbon cycle.
In this experiment it is required to use the germinated seeds without leaves because seeds with the leaves will disrupt the reaction of NaOH and carbon dioxide that will lead to inaccurate oxygen level in the experiment tube.
Thus, the correct answer is :
1. Photosynthesis equation: 6CO2 + 6H2O + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Respiration equation : C6H12O6 + 6O2 --> 6CO2 + H2O + ATP
