Which answer option below describes the best way to increase the accuracy of a
confidence interval calculation?
The accuracy of a confidence interval calculation can be increased from 95% to 99%.
Thus, option C is correct.
What is confidence interval?A confidence interval contain a population parameter in a specified proportion of the time, which can be computed using the given confidence level from a limitless level of individual sample.
The proportion of the range consists of the true value of the factor that will be identical to the confidence level.
In most of the confidence interval examples, the confidence level chosen is 95%. and it can be raise up to 99%.
It cannot estimate the plausible values of the unknown parameter of the population.
Two types of confidence interval observed such as accuracy which is defined based on whether the confidence interval contains the true population parameter or not.
Secondly, the precision defined in terms of the width of a confidence interval.
Hence, option C is correct.

Answer:
EeWw
Explanation:
This question involves two genes; one coding for earlobes and the other for hairline. According to the question, one parent is homzygous recessive for earlobe but homzygous dominant for hairline i.e. (eeWW) while the other parent is homzygous dominant for unattached earlobes but homzygous recessive for hairline i.e. (EEww).
The cross between the two parents is as follows: eeWW × EEww. The following gamete combination will be produced by each parent:
eeWW - eW, eW, eW, eW
EEww - Ew, Ew, Ew, Ew
Using these gametes in a punnet square, the following proportions of offsprings will likely be produced:

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.

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.

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.

Explanation:
These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. What kind of curve would accurately show these changes in the population?
The correct answer is B. S-curve
Explanation
There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

explain how the mammalian skin perform it's role as a thermoregulatory
Answer:
The skin contains many blood capillaries and sweat glands ,the sweat glands secrete sweat when it is hot.when the sweat evaporates from the skin it cools the body.thermoregulation by the skin occurs through dilation and constriction of the blood vessels.when the bodies temperature raises,the blood vessels carry heat in the blood to the skin.the blood capillaries dilate become wider so that more heat can be lost to the environment.this is called vasodilation.when the outside temperature is low,the blood capillaries constrict become narrower so that less blood flows to the surface of the skin.therefore less heat is lost to the environment this is called vasoconstriction.
