Answer:
a) Simplification
b) Disjunctive syllogism
c) Modus ponens
d) Addition
Explanation:
Simplification (also known as conjunction elimination) is an immediate argument form by which is inferred, for example, that if the conjunction A and B is true, then consequently A must be true, and B also must be true. Modus ponens means in Latin "mode that by affirming affirms", this being a mode of deductive reasoning and a rule of inference. A hypothetical syllogism is a valid argumentation mode in which a syllogism, i.e., deductive reasoning that arrives at a specific conclusion by analyzing two different premises, may have a conditional statement for one or both of these premises. A hypothetical syllogism is associated with modus ponens in the way that sometimes it is considered to be a double modus ponens. Addition is a rule of inference that enables the introduction of disjunctions into logical proofs. For example, the rule of addition states that if P is true, then consequently P or Q must be true.

The amount of water a body requires for survival is dependent upon the climate and the individual’s level of physical activity.
The statement "The amount of water a body requires for survival is dependent upon the climate and the individual’s level of physical activity" is true because these factors directly influence the body's water needs.
Climate affects the rate of water loss through sweating and evaporation. In hot and humid climates, individuals tend to perspire more, leading to increased water loss and higher hydration requirements. Similarly, physical activity increases the body's temperature and triggers sweating, resulting in additional water loss.
Engaging in exercise or laborious tasks amplifies the demand for water to replenish the fluids lost during perspiration. Neglecting to meet these increased water needs can lead to dehydration, impaired physical performance, and potential health risks, the statement is true.

In a rabbit, B is the allele for a black coat and b is the allele for the brown coat, what is the genotype of a brown coat
A)bb
B) Bb
C) BB
The correct answer is A) bb
Explanation:
In genetics, an allele is a variation of a gene, which often determines a physical trait. Alleles are classified as dominant if they express even when there are other alleles or as recessive if two copies of the same allele are needed for the gene to express. Moreover, in genetics dominant alleles are represented by uppercase letters while recessive alleles are represented by lowercase letters.
In this context, the allele that is responsible for the brown coat in rabbits is a recessive allele, considering this is represented by lowercase b. This means two copies of the allele are necessary for the rabbit to have a brown coat and therefore the genotype of a brown coat is bb. Also, others such as Bb and BB have the dominant allele related to the black coat, and therefore will lead to rabbits with a black coat.

A student wanted to test the effectiveness of a new type of drug that would partially block Ca2 channels on the sarcoplasmic reticulum. She had a population of 15 frogs and divided them into three groups: 5 frogs received 50mg of the drug, 5 frogs received 25mg of the drug and 5 frogs received a placebo. She isolated a muscle from each frog and measured how much force it exerted during a contraction. She also recorded the air temperature in laboratory because temperature could affect muscle proteins. What was her dependent variable
Answer:
This question is incomplete as it lacks options, the options are:
A. drug dose
B. type of drug
C. force of contraction
D. air temperature
The answer is C. Force of contraction
Explanation:
In an experiment, the DEPENDENT VARIABLE (effect) is the variable that responds to the changes made to the independent variable (cause). It is the variable that is measured as the independent variable is being manipulated in the experiment.
In this case, a student wanted to test the effectiveness of a new type of drug that would partially block Ca2 channels on the sarcoplasmic reticulum. She used a total of 15 frogs, which were divided into three groups and administered different doses of the drug (independent variable). However, the AMOUNT OF FORCE A MUSCLE EXERTED DURING CONTRACTION was measured. Hence, the dependent variable is the force of contraction of the muscle.

name two strata of the epidermis and the process that changes the deepest stratum into the most superficial stratum
The two strata of the epidermis are the stratum basale (also known as the stratum germinativum) and the stratum corneum. The stratum basale is the deepest stratum of the epidermis and is responsible.
The stratum corneum is the most superficial stratum and is composed of dead skin cells that have been pushed to the surface. The process that changes the stratum basale into the stratum corneum is called keratinization or cornification. During this process, cells in the stratum basale epidermis begin to produce a protein called keratin, which gives them their characteristic strength and waterproofing properties. As the cells move upward through the epidermis, they lose their nuclei and other organelles, becoming the flat, scale-like cells of the stratum corneum epidermis . This process is known as cell differentiation, and it takes around 2-3 weeks to complete.

why is it that Radial animals cannot have complex organ systems?
Radial animals cannot have complex organ systems because their body structure and organization are not conducive to the development of specialized organs.
Radial animals have a decentralized nervous system, meaning their nervous tissue is scattered throughout their body rather than being concentrated in a brain or nerve cord. This lack of centralization makes it difficult for them to coordinate and control complex movements or behaviors.
Additionally, radial animals have a simple body plan with few specialized structures. They lack features such as a circulatory system, respiratory system, or digestive system with specialized organs like a stomach, liver, or pancreas. Instead, they have a simple sac-like body with a single opening that serves as both the mouth and anus.
The lack of centralized nervous and organ systems in radial animals limits their ability to carry out complex behaviors and processes that require specialized structures and coordination.

In earthworm, when circular muscles contract and longitudinal muscles relax the body become swells.
Answer:
In earthworms, the body wall consists of two layers of muscles: the circular muscles and the longitudinal muscles. When the circular muscles contract, the diameter of the body wall decreases, and when the longitudinal muscles contract, the length of the body wall shortens.
Explanation:
What is muscles?
Muscles are specialized tissues in the human and animal body that are responsible for movement, stability, and control of the body. They are made up of muscle fibers that are arranged in bundles or fascicles, which in turn are wrapped in connective tissue.
Muscles are controlled by the nervous system and can contract and relax, allowing them to generate force and move bones and other tissues. There are three types of muscles in the body: skeletal, smooth, and cardiac.

What is a major role that fungi play in ecosystems
Answer:
Fungi play a crucial role in the balance of ecosystems. They colonize most habitats on earth, preferring dark, moist conditions. They can thrive in seemingly-hostile environments, such as the tundra. However, most members of the Kingdom Fungi grow on the forest floor where the dark and damp environment is rich in decaying debris from plants and animals. In these environments, fungi play a major role as decomposers and recyclers, making it possible for members of the other kingdoms to be supplied with nutrients and to live.
