Answers
The unconditioned stimulus for the vervent monkey's behavior in this scenario is d. the sight of the hawk circling.
The unconditioned stimulus for the vervent monkey's behavior in this scenario is the sight of the hawk circling.
In classical conditioning, an unconditioned stimulus (US) is a stimulus that naturally elicits a response without any prior conditioning.
In this scenario, the sight of the hawk circling is the unconditioned stimulus because it naturally triggers a response from the vervent monkey.
The presence of the hawk is a potential threat to the monkey's safety, so it instinctively reacts by crying out to warn the other monkeys and prompting them to descend to the ground. The monkey's response is an unconditioned response (UR) because it occurs naturally in the presence of the hawk without any prior learning or conditioning.

Answers
Based on the characteristics provided, we can classify them according to the type of ploidy being described as follows:
Euploidy: Contains the correct number of chromosomes
Very high viability
Monosomy (A type of aneuploidy, or incorrect number of chromosomes): Has an extra chromosome within a pair
Limited viability
Trisomy: Missing one chromosome from a pair
Results from nondisjunction
Very limited viability
Euploidy refers to the condition where an organism has the correct number of chromosomes, which ensures normal development and high viability. On the other hand, monosomy is a type of aneuploidy characterized by the presence of an extra chromosome within a pair, leading to limited viability. Trisomy, another type of aneuploidy, occurs when an individual is missing one chromosome from a pair due to nondisjunction during cell division. Trisomy is also associated with very limited viability, often resulting in developmental abnormalities or health issues.

Answer:
Most living tissue contains catalase. We can use potatoes to help see catalase work because bubbles of oxygen form when we put potatoes into hydrogen peroxide.
Explanation:
As catalase decomposes hydrogen peroxide into water and oxygen gas, bubbles of oxygen collect on the disk. When the density of the combined paper/enzyme/O2 is less than the solution the disc will rise to the surface.
The potato placed in vinegar produced more bubbles than the control because the high temperature improved the function of catalase.

How did the research of Miller and Urey contribute to the hypotheses about the origins of life on Earth?
Answers
Answer:
Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.
Explanation:
Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.
To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.

Explanation:
Arthropods are the largest phyla of the animal kingdom and comprise 80 % of the total animals known. It includes crabs, lobsters, insects, and many other invertebrates. The key features of this phylum make them special and unique to other groups.
These organisms show growth through molten and ecdysis which is the removal of old skin with growth. These organisms have an open circulatory system and the outer layer is made up of chitin that provides a tough exoskeleton. Arthropods have jointed appendages instead of branched or single body. These segments are fused togather and these functional fused segments called tagmata.

Which substance accounts for almost two-thirds of the weight of bone?
-osteocytes
-fibroblasts
-calcium salts
-collagen fibers
Answers
The substance that accounts for almost two-thirds of the weight of bone is calcium salts. Collagen fibers and osteocytes also contribute to the structure of bones, while fibroblasts play a role in bone repair and regeneration.
Calcium is an essential mineral that gives bones strength and hardness. It is stored in the bone matrix as tiny crystals of calcium salts, mainly hydroxyapatite.
Collagen fibers, produced by osteoblasts, make up the remaining one-third of bone weight and provide the flexibility and tensile strength of bones.
Osteocytes are mature bone cells that maintain bone tissue, while fibroblasts are cells that produce collagen fibers in other tissues.
Therefore, the correct option is calcium salts.

[16pts] Prove the following subset inclusion. Use an element argument like those seen in class and in the textbook in Chapter 6. (An B' nC)u(AnBnC) S (AUB) - (BNC).
Answers
We will prove that the subset (A' ∩ B ∩ C) ∪ (A ∩ B ∩ C) is included in (A ∪ B) - (B ∩ C) using an element argument.
Let x be an arbitrary element in (A' ∩ B ∩ C) ∪ (A ∩ B ∩ C). This means that x belongs to either (A' ∩ B ∩ C) or (A ∩ B ∩ C). We will consider both cases separately.
Case 1: x belongs to (A' ∩ B ∩ C)
If x is in (A' ∩ B ∩ C), it satisfies three conditions: it is not in A, it is in B, and it is in C. Since it is not in A, x must be in B. Moreover, since it is in B and in C, it satisfies the condition (x ∈ B) ∧ (x ∈ C), which means it is in (B ∩ C). Therefore, x satisfies the conditions to be in (A ∪ B) - (B ∩ C).
Case 2: x belongs to (A ∩ B ∩ C)
If x is in (A ∩ B ∩ C), it satisfies three conditions: it is in A, it is in B, and it is in C. Since it is in A and in B, it satisfies the condition (x ∈ A) ∧ (x ∈ B), which means it is in (A ∪ B). However, since it is in B and in C, it also satisfies the condition (x ∈ B) ∧ (x ∈ C), which means it is not in (B ∩ C). Therefore, x also satisfies the conditions to be in (A ∪ B) - (B ∩ C).
In both cases, we have shown that x satisfies the conditions to be in (A ∪ B) - (B ∩ C). Since x was arbitrary, we can conclude that every element in (A' ∩ B ∩ C) ∪ (A ∩ B ∩ C) is also in (A ∪ B) - (B ∩ C), proving the subset inclusion.
