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.
Please help fill in the blanks: The torso, which houses the apparatus consists of upper and lower cavities that are partitioned by the____#1____.The upper cavity is called the __#2___ (or colloquially the chest) and is almost totally filled with the heart and lungs; the lower the cavity, the abdomen or belly, contains much of the __#3__ and other organs and glands.
Answer:
The torso, which houses the apparatus consists of upper and lower cavities that are partitioned by the diaphragm.The upper cavity is called the thorax (or colloquially the chest) and is almost totally filled with the heart and lungs; the lower the cavity, the abdomen or belly, contains much of the digestive system and other organs and glands.
Explanation:
The torso is an important part of the body that contains many of our organs, and its integrity is fundamental to our survival.
The torso is divided into two big cavities (thorax and abdomen) by the diaphragm, the most important muscle involved in breathing. The diaphragm has three large openings that allow the passing of the esophagus, and some blood vessels and nerves from the thorax to the abdomen, and vice versa.
Inside the thorax there's the lungs and the heart, which are separated into specific cavities: the pleural cavity, formed by the two layers of a membrane that envelops the lungs called pleura; and the pericardial cavity, formed by the two layers of the pericardium, which surrounds the heart and the large vessels.
The abdomen holds most of the digestive system, like the stomach, the liver, and the intestines, and has other important organs as well such as the kidneys. The organs from the digestive system are held in place by another membrane called the peritoneum.
isolation occurs when two species occupy different habitats within the same geographical range.
Question:
_____ isolation occurs when two species occupy different habitats within the same geographical range.
Answer:
Habitat
Explanation:
Habitat isolation occurs when individuals in two populations are separated geographically. For example by a river or a mountain range. These organisms are much less likely to interact with each other and attempt to reproduce.
Habitat isolation is a barrier to gene flow (mixing of genes in two populations) and is a mechanism of speciation.

Organisms can form several types of symbiotic relationships. From the descriptions, determine if each of the symbiotic relationships is an example of commensalism, mutualism, or parasitism. 1. Hermit crabs protect themselves from predators by living in shells discarded by snails. 2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees. 4. The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia. 5. The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host. 6. On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites. 7. Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves.
Answer:
From the questions, here are the answers.
1 is commensalism
2. Parasitism
3. Parasitism
4. Mutualism
5. Parasitism
6. Mutualism.
7.Commensalism
Explanation:
Hermit crabs protect themselves from predators by living in shells discarded by snails and Cattle egrets follow cattle and other large grazing animals and eat the insects stirred up by cattle's hooves relationship is commensalism because commensalism is a symbiotic relationship that take place between two organisms in which one benefits and the other is neither harmed or does not benefit. Hermit crabs benefit by receiving protection from snail shells and snail does not benefit and not harmed. Cattles eagret feed on insects on cattle hoolves, cattle is not harmed or does not benefit
Parasitism
2. Ticks attach to humans in order to eat human blood. Ticks can also infect humans with Rocky Mountain spotted fever and Lyme's disease. 3. The coralroot orchid is a reddish color and is unable to photosynthesize. These orchids take carbohydrates from pine trees through connections formed between their roots and the roots of the pine trees and The Leucochloridium worm infects snails and is able to control the snail's behavior, creating a zombie-like snail. The worm forces the snail to attract predators to itself so that the worm is eaten and passed to its next host are parasitism relationship because parasitism is a relationship that exists between two organisms in which the other called the predator infect , harm or cause damage to the host organism. The above are parasitism relationship because they cause damage to their host.
Mutualism
The bullhorn acacia grows special tissues in which ants live. The ants find a safe place to live and attack any animals that attempt to graze on the acacia and On the Galapagos Islands, there are finches that remove parasitic insects from tortoises. The finches gain a meal and the tortoises are ridded of parasites exhibit mutualism relationship because mutualism is a symbiotic relationship that exists between two organisms in which both benefits from the relationship. The Acasia and the ants receive protection from the relationship. The finches and tortoise benefited from their relationship.

F. What happens to the speed of the particles when a gas is cooled?
Plzzz help it's due today ik I'm dumb but please help me
Answer:
a. As a container of confined gas is heated, its molecules increase in kinetic energy and push the movable piston outward, resulting in an increase in volume.
B. When you heat them,you essentially give them kinetic energy which increases their speed and hence the distance between molecules increases implying that interatomic forces decreases,leading to change in state from solid to liquid
C. When the gas is heated the particles gain kinetic energy which makes them move faster. This means they collide with the walls more frequently and with greater force and so the pressure increases.
D. Both the increase in pressure and the decrease in temperature cause the volume of the gas sample to decrease. Since both changes are relatively small, the volume does not decrease dramatically.
E. When an object is heated the motion of the particles increases as the particles become more energetic. If it is cooled the motion of the particles decreases as they lose energy.
F. Cooling slows the velocities of the He atoms, causing them to behave as though they were heavier. 6. Both the temperature and the volume are doubled for this gas (n constant), so P remains constant. (a) The number of collisions per unit area of the container wall is constant.

4. What material passes through a hole of a strainer when sieving
is used to separate mixtures?
Answer:
Explanation:
A strainer is a device that is used to remove foreign/specific "dirt" from a liquid (usually when flowing). Strainers usually have holes just like a sieve except that this time, it separates dirt (tiny solids) from the liquid unlike a sieve that separates solid particles of different sizes.
It should however be noted that sometimes the strainer is designed to remove a valuable "dirt" from the flowing liquid.
Very small particles such as fine flour particles can pass through the hole of the strainer.
Those particles which are smaller in size of the hole of the strainer can pass through it while on the other hand, large particles can pass through it. Sieving allows the fine flour particles to pass through the holes of the sieve but prevent or stops the bigger particles from entering the sieve so we can conclude that very small particles can pass through the hole of the strainer but the large particles can't.

Explanation:
Why do you think catalase has to work so quickly?
Answer:
Hydrogen peroxide is toxic.
Explanation:
Hydrogen peroxide is a natural product of the reactions in the cell. However, it is toxic to cells and has to be broken down.
Catalase catalyses the breakdown of hydrogen peroxide into water and oxygen. It is found in all living cells and is very important to prevent the build up of hydrogen peroxide. If catalase didn't work quickly, hydrogen peroxide would accumulate in the cell and poison it, causing the cell to die.

Describe the differences and similarities between mitosis and binary fission.
Answer:
Binary fission is a method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning. Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.
Explanation:
Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.
What is mitosis?Mitosis is cell division that results in two identical daughter cells and is primarily used for growth of an organism.Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
The chromosomes are separated by a structure called the mitotic spindle. A chromosome is a lengthy DNA molecule with component or all of the genetic material of an organism. In maximum chromosomes the very lengthy skinny DNA fibers are lined with packaging proteins; in eukaryotic cells the maximum vital of those proteins are the histones.
These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to keep its integrity. These chromosomes show a complicated third-dimensional structure, which performs a large position in transcriptional regulation. Chromosomes are generally seen below a mild microscope best for the duration of the metaphase of molecular division.
Therefore, Binary fission has been known as method of asexual reproduction which single-celled organisms, usually prokaryotes, use to create a copy of themselves. Another term for the process is cellular cloning.
