Whose argument is stronger regarding the SAC curves and the LAC curve? A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC. B. Jacob Viner since the SAC curves can be adjusted slightly and still keep their U-shape in a way that makes their lowest points end up on the LAC curve. C. Jacob Viner since the long-run average cost curve must be composed of the lowest points on any individual short-run average cost curve. D. The draftsman since, while it is true that the points of tangency of the SAC curves with the LAC curve are at each SAC curve's minimum, it is impossible to illustrate it accurately.
NB: This is a business question, not biology.
Answer:
SAC (Short-run Average Cost) and LAC (Long-run Average Cost)
The stronger argument regarding the SAC (Short-run Average Cost) curves and the LAC (Long-run Average Cost) curves is:
A. The draftsman since the lowest point on each SAC curve will have a horizontal tangent line which only occurs at the lowest point on the LAC.
Explanation:
The costs of all factors of production become variable in the long run. But in the short-run, some costs are variable, and some are fixed. When the producer starts operating over the long run period, it can then operate without the constraints imposed by the presence of the fixed-cost factors. Therefore, in the long run, the average cost (LAC) is equal to the short-run average cost (SAC) because there is an unconstrained minimum average cost at all output levels.

Thymine in DNA occurs as the result of thymidylate synthase creating _______________ , which then undergoes ____________ to ____________, then to __________, and incorporated into DNA by ___________.
Answer:
The question is incomplete, the complete question is as follow:
Thymine in DNA occurs as the result of thymidylate synthase creating _______, which then undergoes _______ to _______, then to _______, and incorporated into D N A by _______. Thymine in tRNA arises ________, by an S-adenosylmethionine-dependent _______ of a ______ residue in RNA.
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating dTMP, which then undergoes phosphorylation to dTDP, then to dTTP, and incorporated into DNA by DNA polymerase. Thymine in tRNA arises posttranslationally, by an S-adenosylmethionine-dependent methylation of a UMP residue in RNA.
Explanation:
Thymidylate synthase is a key enzyme that catalyzes the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) from 2′-deoxyuridine-5′-monophosphate (dUMP). This enzyme catalyzes the addition of a phosphate group (phosphorylation) of dTMP in order to form thymidine 5'-diphosphate (dTDP). Once synthesized, dTMP can be metabolized to deoxythymidine triphosphate (dTTP), which is a precursor for DNA biosynthesis. On the other hand, transfer ribonucleic acid (tRNA) is methylated after the molecule is synthesized. The transfer of the methyl group is catalyzed by an S-adenosylmethionine–dependent methyltransferase that catalyzes the methylation of uridine monophosphate (UMP) using SAM (S-adenosylmethionine) as the methyl donor.

The frequency of a lethal allele in a population is greatest when it is: Group of answer choices dominant manifested in infancy recessive co-dominant
Answer:
recessive
Explanation:
A lethal allele is a gene variant associated with a mutation in an essential gene, which has the potential to cause the death of an individual. In general, lethal genes are recessive because these alleles do not cause death in heterozygous individuals, which have one copy of the normal allele and one copy of the allele for the lethal disease/disorder. In recessive lethal diseases, heterozygous individuals are carriers of the recessive lethal allele and can eventually pass the 'defective' allele on to offspring even though they are unaffected; whereas dominant lethal diseases are caused by dominant lethal alleles, which only need to be present in one copy to be fatal. In consequence, the frequency of recessive lethal alleles is generally higher than dominant lethal alleles because they can be masked in carrier individuals. Some examples of human diseases caused by recessive lethal alleles include, among others, Tay-Sachs disease, sickle-cell anemia, and cystic fibrosis.
The frequency of a lethal allele in a population is greatest when it is: C. recessive.
A lethal allele can be defined as an allele that is responsible for the death of a living organism, especially by preventing its development. Thus, a lethal allele causes a complete mortality in the living organism carrying it, in a hom-ozygous condition.
Basically, a lethal allele is recessive in nature because it is expressed in the phenotype of an organism. Some examples of diseases caused by lethal alleles in humans are:
Cystic fibrosisSickle-cell anemiaAchondroplasiaIn conclusion, a lethal allele that is recessive has the greatest frequency in a population.

What is algal bloom?
The rapid increase in production of algae in freshwater and marine water system is called algal bloom. It is also known as the discoloration of water from the algal pigment.What causes algal bloom?
Excessive nitrogen and phosphorus cause overgrowth of algae.The overgrowth of algae consumes oxygen and blocks sunlight from underwater plants. When the algae eventually dies, the oxygen in the water is consumed.As the river and streams are always flowing it will sweep the algae which will prevent it from growing further.

Which is the main light-absorbing pigment for photosynthesis?
O carotene
O chlorophyll
O hemoglobin
O anthocyanin
Answer:
ChlorophyllExplanation:
Chlorophyll, the primary pigment used in photosynthesis, reflects green light and absorbs red and blue light most strongly.
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll.
Answer:
B) Chlorophyll
Explanation:
The chloroplasts, which contain the green pigment chlorophyll, are where photosynthesis takes place. Chlorophyll is the pigment that gives plants their distinctive color. It works by collecting the energy in the sunlight that strikes the plant. Because grass requires photosnthesis to create glucose, which is required for growth inside the grass, photosynthesis is critical to life on Earth. As a result, creatures that eat the grass get energy, and so on. As a result, photosynthesis is the mechanism through which energy is introduced into an environment.

Which structures allow lycophytes to grow bigger than mosses and liverworts?
A. gametophytes and sporophytes
b. xylem and phloem
C. haploid and diploid
D. roots and stems
The structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem which is option B
Lycophytes are spore bearing vascular plants. Being a vascular plant, they possess vessels ( vascular tissues) which include:
ylem: this is used for conducting water usually from the root to the rest of the plant partsPhloem: this is the vascular tissue that is used to conduct food( sugar) produced in the leaves of plants to other parts of the plant.The possession of the vessels makes the lycophytes appear bigger.
Mosses and liverworts belongs to the plant phylum Bryophyta. They do not have any vascular tissues that can be used to conduct water and food. This restricts their size.
Therefore, the structure that allows lycophytes to grow bigger than mosses and liverworts is xylem and phloem

In large populations, small fluctuations in survivorship or reproduction among individual organisms are unlikely to affect allele or genotype frequencies in the population.
a. True
b. False
Answer: True.
Explanation:
A population is defined as the set of individuals that inhabit a given geographic area. A population has a certain allele frequency, which is the measure of the relative proportion of alleles in a given population, expressed as a percentage or unit. It is estimate using the number of times the allele is found in a locus and dividing it by the total number of alleles. While the genotypic frequency refers to the number of times that each of the genotypes generated by the two-by-two combinations of the alleles involved in the locus under study appears in relation to the total number of genotypes (which will be equal to the total number of individuals included in the study).
The population can be increased or decreased according to the birth and death rates. Generally, unless specific alterations occur, such as the spread of a disease, immigration, emigration, natural disasters, and others, the size of the population will remain constant. This means that the birth rate is quite similar to the death rate. And the larger the population, the more difficult it is to disturb this balance between births and deaths. So if small fluctuations in survival or reproduction occur between individuals, it is unlikely that this will affect the frequency of alleles and/or genotypes. This is explained using the Hardy-Weinberg principle states that the genetic composition of a population remains in equilibrium as long as no mutation occurs, and nor natural selection nor any other factor acts. After a generation of random mating, the frequencies of the genotypes of a locus are fixed at an equilibrium value. Then, the genetic variation in a population will remain constant from one generation to the next in the absence of extreme disturbing factors such as those mentioned above (diseases, natural disasters, and others).
Note that for this principle to be fulfilled, the population must be diploid (have two alleles of each gene), must reproduce sexually in a random manner, and must be large enough to minimize the effect of genetic drift (random fluctuations in allele frequencies from one generation to the next, due to random events that can cause certain traits to become dominant or disappear from a population).

A. the expression of a dominant phenotype in a heterozygote.
B. the increased expression of a particular trait when a hybrid species is formed.
C. the expression of one gene masking the effects of another gene.
D. quantitative traits that diminish or intensify a particular phenotype.
E. the influence of environment on the expression of a particular genotype.
Answer:
the influence of environment on the expression of a particular genotype.
Explanation:
In genetics, we define penetrance as the proportion of individuals in a given population carrying a particular gene/allele which leads to the expression of the particular trait associated with that gene/allele.
Expressivity is defined as the degree of expression of a given phenotype by individuals who possess a particular genotype. Expressivity shows the extent of variation in expression of genes by individuals having a particular genotype.
Both penetrance and expressivity has to do with the influence of environment on the expression of a particular genotype.

What is the correct order of the levels of organization in animals from smallest to largest?
Answer:
Molecules, cells, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere are in the correct order of the organization's levels.
Explanation:
Molecule: Atoms, the smallest unit of chemical elements are built up of molecules. You can find it in any matter, whether it lives or not. The most fundamental structures of biological creatures are molecules. Biochemistry and molecular biology are two biological fields focused on this level.
Cell: A cell is the basic unit of life. Two types of cells exist plant cells with a stiff cell wall consisting of cellulose molecules and animal cells with a flexible cell membrane. Cell biologists examine problems like metabolism and other structure and functional questions within and between cells.
Tissue: Tissue consists of cells working together to accomplish a goal. Some tissues include muscle, connective tissue, and neural tissue. Examples of biologists working at this level are histologists.
Organ: An organ is a tissue system that works at bigger scales together to perform specified work in the body of an animal. Brain, heart, and lungs are examples of organs. Anatomy is an example of a specialty in biology which concerns this level.
Organ system: An organ system is a group of bodies that work together to fulfill certain activities of the body. Air systems are used to inhale oxygen and release carbon dioxide in animals, for example, by the lungs, respiratory tract, and muscles. The function of the corpus when working jointly is studied by physiologists. Although physiologists can work at any level, they commonly address queries about organ systems.
Organism: An organism is an autonomous and recognized person. The organisms might be single-cell or multi-cell organisms consisting of organisms and organ systems, as well as bacteria, amiable, or creatures. An example of a multi-cellular organism is a human being.
