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.
Answers
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.

(Free Response) 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.
D. Provide reasoning and justification for your prediction.

PLEASE HELP! WILL GIVE BRAINLIEST. Describe the contribution of photosynthesis and cellular respiration to the exchange of carbon between the atmosphere and the biosphere.
Answers
Cellular respiration and photosynthesis are essential to the carbon cycle because cellular respiration involves the intake of oxygen o2 and the exhale of carbon-dioxide co2 into the atmosphere. Where photosynthesis uses the carbon dioxide and water to create oxygen and sugars through energy to repeat the cycle. Respiration in general is a process where carbohydrates are turned into dihydrogen monoxide or water and co2(carbon dioxide). Living organisms together throughout the biosphere and atmosphere work together to continue this because carbon itself is an organic substance.
Answer:
Explanation: Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

Example: you are inferring that the fossil was a stegosaurus fossil off of evidence or reasoning.
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.

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.

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.
