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.

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.
Calculate the final concentration of BSA in the problems below using the formula
C1*V1 = C2*V2,
where C1 and V1 are the concentration and volume of the starting solution, and C2 and V2 are the concentration and volume of the final diluted solution. Include proper units and show your work for full credit.

C. 10 ul of 1 mg/ml BSA is mixed with 990 ul TBS.
D. 10 ul of 0.1 mg/ml BSA is mixed with 990 ul TBS.
Answer:
A. [tex]C_2=1.5\frac{mg}{mL}[/tex]
B. [tex]C_2=0.075\frac{mg}{mL}[/tex]
C. [tex]C_2=0.01\frac{mg}{mL}[/tex]
D. [tex]C_2=0.001\frac{mg}{mL}[/tex]
Explanation:
Hello.
In this case, we must compute the final concentration in all the cases so we solve for it in the given equation:
[tex]C_2=\frac{C_1V_1}{V_2}[/tex]
Thus, we proceed as follows:
A. Here, the final diluted solution includes the 300 μL of the 5 mg/ml-BSA and the 700 μL of TBS.
[tex]C_2=\frac{300\mu L*5\frac{mg}{mL} }{(300+700)\mu L}\\\\C_2=1.5\frac{mg}{mL}[/tex]
B. Here, the final diluted solution includes the 50 μL of the 1.5 mg/ml-BSA, the 450 μL of water and the 500 μL of TBS.
[tex]C_2=\frac{50\mu L*1.5\frac{mg}{mL} }{(50+450+500)\mu L}\\\\C_2=0.075\frac{mg}{mL}[/tex]
C. Here, the final diluted solution includes the 10 μL of the 1 mg/ml-BSA and the 990 μL of TBS.
[tex]C_2=\frac{10\mu L*1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.01\frac{mg}{mL}[/tex]
D. Here, the final diluted solution includes the 10 μL of the 0.1 mg/ml-BSA and the 990 μL of TBS.
[tex]C_2=\frac{10\mu L*0.1\frac{mg}{mL} }{(10+990)\mu L}\\\\C_2=0.001\frac{mg}{mL}[/tex]

(Q005) Humans are unusual because our cultural practices can actually change our environmental circumstances. We can change the environment in which natural selection acts on our traits. Describe how this process has played out in the evolution of adult lactose tolerance. Can you hypothesize any similar situations where our future evolution may be influenced by cultural practices we have today
Answer:
Lactose tolerance conferred an evolutionary advantage, thereby this beneficial mutation increased its frequency in the population
Explanation:
Originally, adults were unable to digest lactose. But approximately 8,000-10,000 years ago something remarkable happened: a mutation near the gene that produces the lactase enzyme appeared in a raising cattle population from Europe-Middle East, making adults able to digest lactose. Nowadays, many adults from different societies are tolerant to digest lactose because this mutation increased its frequency and extended to different populations. It is a classical example of how a beneficial mutation may eventually become the most common gene variant by increasing its frequency in the population, and, subsequently extending to other populations. It is possible to hypothesize that new mutations associated with human activities may appear in current human societies, thereby conferring an evolutionary advantage in the same way that lactose tolerance in cattle-raising people. For example, nowadays, mutations in human behavior-associated genes might confer beneficial social skills (thereby increasing the frequencies across time or across populations).
Which of the following statements correctly describes some aspect of protein excretion in prokaryotic cells? a Prokaryotes are unlikely to be able to excrete proteins because they lack an endomembrane system. b The mechanism of protein excretion in prokaryotes is probably the same as that in eukaryotes. c Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. d In prokaryotes, the ribosomes that are used for the synthesis of secreted proteins are located outside of the cell. e Prokaryotes contain large pores in their plasma membrane that permit the movement of proteins out of the cell.
Answer:
The correct answer is option c "Proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane".
Explanation:
Many prokaryotes secrete proteins, particularly, extracellular enzymes that have a function outside the cells and toxins that are not needed by the cell. As any other protein, proteins that are excreted by prokaryotes are synthesized on ribosomes that are bound to the cytoplasmic surface of the plasma membrane. However, excreted proteins go to the general secretion (Sec) pathway, where they are tagged and further processed.
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.

1. What did Linnaeus use to classify living things?
Answer:
Perhaps the single greatest contribution Linnaeus made to science was his method of naming species. This method, called binomial nomenclature, gives each species a unique, two-word Latin name consisting of the genus name and the species name. An example is Homo sapiens, the two-word Latin name for humans.
Explanation:
Can I have brainliest
It is from Google
Binomial nomenclature, which Carolus Linnaeus created, is a system for categorizing living things. Linnaeus was a Swedish botanist and biologist.
Binomial nomenclature is a biological system for naming organisms.
It is quite difficult to identify an organism internationally and keep track of the number of species when it has multiple local names.
Some of the features of binomial nomenclature that Linnaeus used to classify living things are:
Latin names are used because they are universal and consistent.
The process of naming each organism uniquely using the two words "genus" and "species."
The arranging of living things into a hierarchy, with each organism being given a position based on how similar it is to others.
Humans, for instance, are known as Homo sapiens. Its name, Homo, translates to "man" in Latin. The name of the species, sapiens, means "wise".
Therefore, Binomial nomenclature is used by Linnaeus to classify living beings.
