Which statement describes the proper procedure for identifying an organism by using a dichotomous key?
Explanation:
A dichotomous key is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. Keys consist of a series of choices that lead the user to the correct name of a given item. "Dichotomous" means "divided into two parts".

Which of these is an example of an environment in which natural selection would not occur?
Group of answer choices
A. There is genetic diversity in the population due to mutation and/or sexual reproduction.
B.All offspring have the same chance of survival.
C. Offspring inherit beneficial and detrimental traits from parents.
D. Some offspring have a physical trait that helps the organism compete more successfully.
An example of an environment in which natural selection would not occur is a place where all offspring have the same chance of survival. Thus, the correct option for this question is B.
What is Natural selection?Natural selection may be defined as a type of strategy or process in nature through which organisms particularly gets better adapted to their environment and tend to survive and reproduce more than those less adapted to their environment.
Genetic diversity always favors the process of natural selection to occur. And this genetic diversity is generally induced by evolutionary forces like genetic drift, mutation, migration, etc.
Apart from this, offspring inherit beneficial and detrimental traits from parents and offspring have a physical trait that helps the organism compete more successfully and are also more prone to natural selection.
Therefore, an example of an environment in which natural selection would not occur is a place where all offspring have the same chance of survival. Thus, the correct option for this question is B.

I'd say FLPE is the worst. It can run high temperatures but it's not safe and not safe with all foods, it's has a high cost.
Explain this term as related to fossils.
inference
To figure out something based on observation or provided information is termed an inference. Information about the fossils is used by geologists to draw inferences about the organisms that existed long ago.
What are fossils?Fossils are the remains of once-alive organisms that are altered geologically. The dead remains of past lives had been preserved by the earth's crust. They are of interest to geologists and are used to determine the age of rocks
Any living creature – animal, plant, bacteria, and fungus – can be fossilized, but because fossilization is a process of destruction, not all fossilized organisms survive. Most fossilized organisms are consumed, rot or die out in the environment before they can become fossils.
Under normal conditions, only the outermost layers of the most difficult animals and plants fossilize. However, sometimes the conditions are right to fossilize entire soft-bodied organisms.

Answer:
because both balloons have the same charge and are repelling against each other.
Explanation:
because the static charge coming off the balloons is pushing the balloons away from each other
A Student charges two balloon and hangs them side by side. because both balloons have the same charge and are repelling against each other.
What is Balloon?A balloon is a stretchy bag that can be filled with helium, hydrogen, nitrous oxide, oxygen, or air.
Balloons can be filled with smoke, liquid water, granular media (such sand, grain, or rice), or light sources to perform certain jobs.
Modern balloons can be found in a wide range of colors and are produced from materials like rubber, latex, polychloroprene, or a nylon fabric. Early balloons, like the pig bladder, were occasionally fashioned of dried animal bladders.
Therefore, A Student charges two balloon and hangs them side by side. because both balloons have the same charge and are repelling against each other.

Phototropism is a phenomenon observed in plants. Phototropism is best described as a plant’s response to light. Auxin is a hormone and signaling molecule found in plants that promotes cell elongation. It is observed that auxin concentrations are lower in the parts of the plant that are closest to light. Auxin concentrations are higher in the parts of a plant that are in the shade.
Answer the following in the space provided.
A. Describe phototropism using what you know about signal transduction. Start with auxin as a signaling molecule.
B. Explain how altering the receptor would affect the signaling pathway.
C. Predict how a plant would respond to exposure to light on all sides of a growing stem.

genes.
In the blood group systems, the phenotypes largely depend on the genotype.
A phenotype is an observable trait of an organism, which depends on the genotype, environment, or both.For example, the blood group system ABO is dependent on the presence of certain antigens on the surface of blood cells.In this system, A and B are codominant alleles, whereas O is recessive and therefore it is not expressed in heterozygous individuals.In conclusion, in the blood group systems, the phenotypes largely depend on the genotype.

In the blood group system, the concept of Co-dominance is applied, where the phenotypes depend on the genotypes.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or the manifestation of characters. Phenotypes are also known as traits.
Co-dominance is a condition where both alleles in heterozygous conditions give visible expression. ABO blood group system in humans depends on certain antigens on the surface of blood cells. Alleles A and B are co-dominant while allele O is recessive.
Therefore, in the blood group system, the concept of Co-dominance is applied, where the phenotypes depend on the genotypes.
