What is the significance of flatworms being flat?

Answers

Answer 1
Answer: Flatworms (Platyhelminthes) are phylum of unsegmented, soft, flat invertebrates. 

Flatworms have no body cavity which is why they are flat. The advantage of a flat body is facilitated respiration and circulation. Flatworms do not have respiration and circulation system. But, oxygen diffuses across the skin and reach all parts of the body thanks to a flattened shape. Also, it is easy to hide from predators because they can get almost everywhere thanks to the body shape.

Which group of substances is arranged in order of decreasing specific heat values?

Answers

Final answer:

The specific heat values of different substances can be arranged in order of decreasing specific heat.

Explanation:

The specific heat of a substance is the amount of heat energy required to raise the temperature of a given mass of that substance by a certain amount. The specific heat values of substances can vary, so they can be arranged in order of decreasing specific heat.

Water has a high specific heat and iron has a low specific heat, which means it takes longer for water to heat up or cool down compared to iron. Other substances can also be arranged in order of decreasing specific heat based on their specific heat values.

For example, if we compare different gases, we can arrange them in order of decreasing specific heat values. The specific heat of nitrogen (N₂) is lower than that of oxygen (O₂), and the specific heat of oxygen is lower than that of carbon dioxide (CO₂).

Which term is not the name of a classification level?a. allele
b. kingdom
c. order
d. phylum

Answers

Allele is not the name of a classification level because its not a part of taxonomical hierarchy. Therefore, option (A) is correct.

What is Taxonomic Hierarchy?

Taxonomic rank is the relative level of a group of organisms, known as a taxon, within an ancestral or hereditary hierarchy. This term is used in the field of biological categorization.

The Linnean system is the foundation for the modern method of classification, which consists of eight different levels of taxa. These levels, which are listed from most general to most specific, are as follows: domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.

How do haplorhines differ from strepsirhines? a. Haplorhines have a smaller brain relative to body size. b. Haplorhines have better color vision. c. Haplorhines have a tail. d. Haplorhines are less dimorphic sexually.

Answers

Answer:

The answer is B: Haplorhines have better color vision.

Explanation:

Haplorhines are known as dry-nosed while Strepsirhines are known as wet-nosed.  Haplorhines and Strepsirhines are two different kind of primates but they have different characteristics such as variation of the brain size, because Haplorhines have bigger brain than Strepsirhines, Haplorhines do not have the enzyme in charge of producing Vitamin C while Strepsirhines have it. Haplorhines have a more developed vision than Strepsirhines. In this sense, Haplorhines possess a layer called tapetum lacidum which allows them to see at night when the light is low, while Haplorhines do not possess tapetum lacidum but, they have something called fovea, which help the to see during the day and have a vision color which is not a feature of Strepsirhines.

Final answer:

Haplorhines and Strepsirrhines are two main classifications of the Order Primates. Strepsirrhines are the wet-nosed primates, primarily nocturnal with larger olfactory centers. Haplorhines, dry-nosed primates, are often diurnal, rely more on vision and need vitamin C from their diet.

Explanation:

The Order Primates is segregated into two groups: Strepsirrhini (“turned-nosed”) and Haplorhini (“simple-nosed”) primates.

Strepsirrhines, also known as the wet-nosed primates, include prosimians like bush babies and pottos of Africa, the lemurs of Madagascar, and the lorises of Southeast Asia. These primates are primarily nocturnal, have larger olfactory centers in the brain, and tend to be smaller in size with smaller brains compared to anthropoids.

On the other hand, Haplorhines, or dry-nosed primates, include tarsiers and simians (New World monkeys, Old World monkeys, apes, and humans). Typically, Haplorhines are diurnal, rely more on their vision, and lack enzymes to produce vitamin C, thus, needing to get it from their food. Distinctive anatomical traits of strepsirrhines include a grooming claw on their second toe and protruding incisors forming a toothcomb. Haplorhines further diversify into Simiiformes and Tarsiiformes with distinctions being narrow nostrils, non-existent or functional tails, and their habitat.
