When Carter first moved into his neighborhood, he noticed hundreds of frogs on the roads after a rain storm. Lately, Carter has seen less than four or five frogs on his five-minute drive through the neighborhood. Which of the recent events is a reasonable conclusion based on Carter's observations? A drought has impacted the population size of the frogs. A new housing development has led to extinction of the frogs. The beginning of the winter has created temperatures too cold for the frogs. Increasingly warm temperatures have dried the skin of the frogs leading to death.

Answers

If you think about a lot of frogs need water to sustain themselves because that is where they were born; in the water. So the answer would be that "A drought has impacted the population size of the frogs". Because of this drought, there is no water for the frogs, so they either die or find somewhere else to go.

Answer:  A drought has impacted the population size of the frogs.

Explanation:

The frogs are the amphibians who require both water and terrestrial habitats to survive and reproduce. The rainwater accumulates over the terrestrial regions can provide an ideal environment for the survival of the frogs.

According to the given situation, Carter noticed hundreds of frogs on the road after rain storm as the road environment was suitable for the survival of the frogs. But later on he observed less than four or five frogs. This may be because of the fact that the road might not be left with water which could be probably due to drought (a drought is a condition where a region does not receive appropriate amounts of rainfall which leads to the dry and hot environment).

A wedge-capped capuchin is a species of South American monkeys. They live in groups that typically have one male and several females. Sometimes young males live in a group too in order to help take care of the young. Most groups have a dominant female that often displays aggression toward other females and young males in the group. Which best describes the group behavior of these monkeys? territorial imperative social hierarchy migratory hibernating

Answers

social hierarchy as there are dominant monkeys over a group

Answer:

The correct answer would be the social hierarchy.

Explanation:

A basic aspect of social organization that is decided by display behavior or fighting and leads to a ranking system or order of place of the animals in a group is known as social hierarchy.

Dominance type of social hierarchies often decided best or early access to mating, social interactions, or food within animal groups.

Wedge-capped capuchin monkeys show this type of social hierarchy in their pack or group where dominant females display aggression towards other young males and females.

Thus, the correct answer is the social hierarchy.

Which two factors are mostly responsible for recent rapid globalization?

Answers

Advances in transportation and communication, alongside reduced trade barriers, have been key factors contributing to rapid globalization.

Advances in transportation and communication have significantly reduced the costs of moving goods globally, particularly with the development of shipping containerization in 1956. This innovation lowered transportation costs by up to 90% and facilitated the movement of goods worldwide. Secondly, the reduction of trade barriers between countries has played a crucial role in the rapid globalization process, making it easier for goods and services to flow across borders.

Many biologists argue that the euglenoids should be classified as an animal-like protist rather than a plantlike protist

Answers

Euglenoids are a group of unicellular organisms with both animal-like and plant-like traits, leading to classification challenges. Taxonomy and phylogeny based on molecular genetics and genome analysis have led to a restructuring of the kingdom Protista into multiple monophyletic supergroups, taking into account convergent evolution.

The question addresses the classification of euglenoids, which are unicellular organisms with both animal-like and plant-like characteristics. This classification ambiguity arises because euglenoids exhibit mobility and some are heterotrophic, which are traits associated with animals, leading zoologists to sometimes refer to them as 'Euglenozoa'. On the other hand, some euglenoids are capable of photosynthesis, a plant-like trait, causing botanists to call them 'Euglenophyta'. The taxonomy and phylogeny of euglenoids, and protists in general, have been reshaped with the advent of molecular genetics and genome analysis. These analyses have revealed deep evolutionary branches within the domain Eukaryota, dividing it into several monophyletic supergroups. The classification continues to evolve as new genetic information is discovered, making clear that morphologically similar protists may not necessarily share a recent common ancestor—a concept known as convergent evolution.

A large plant population may impose selective pressure on a smaller, isolated group of plants, resulting in a change in allele distribution. which mechanism is responsible for this change in the allele distribution? mutation hybridization trait acquisition genetic drift

Answers

The answer is genetic drift. This is the change of allelic frequency in a population due to natural selection in favor of particular traits. The effect of natural drift is greater is a population of small size that in a big population. When the allelic frequency of the isolated group of plants reaches 0, it is deemed as lost.

How much time passed between the appearance of the first prokaryotic cells and the emergence of multicellular organisms?

Answers

Prokaryotes were the first organisms to evolve on Earth, so, the first prokaryotic cells appeared 3.8 billion years ago. After them, Eukaryotic unicellular organisms developed, when one cell engulfed the other cell (endosymbiotic theory). Those unicellular eukaryotes form multicellular aggregates and that represents an evolutionary transition from single cells to multicellular organisms. Multicellular organisms evolved from unicellular eukaryotes at least 1.7 billion years ago.

About 2 billion years passed between the appearance of the first prokaryotic cells and the emergence of multicellular organisms.

 

Final answer:

The first prokaryotic cells appeared about 3.5 billion years ago, while the first definite multicellular organisms with tissues evolved around 630-542 million years ago. Between these milestones, eukaryotic cells emerged about 2.1 billion years ago.

Explanation:

The evolution of life on Earth began with the appearance of the first prokaryotic cells around 3.5 billion years ago. These cells were the only life forms for about 1.4 billion years until the appearance of eukaryotic cells approximately 2.1 billion years ago. As eukaryotes evolved, they became more complex, leading to the development of multicellularity about 1.5 billion years ago. However, the oldest definite multicellular organisms with tissues, as evidenced from the Ediacaran period, evolved around 630-542 million years ago. It's important to note that these estimates are based on fossil records and genetic evidence, and exact timings may vary slightly based on different sources.

There are two bird species on a midwestern prairie that look very much alike physically and are probably descended from a common ancestor. during courtship, however, the males of one species stands on one leg while looking at the female. the males of the second species uses both feet to drum on the prairie floor. the females will only mate with those males who behave appropriately during courtship. what is this an example of?

Answers

I believe this is an example of Behavioral isolation. Behavioral isolation is an evolutionary mechanism that helps members of the same species identify each other as proper mates. It involves differences in courtship or mating behaviors; unlike temporal isolation which involves differences in the timing of courtship or mating behaviors

a. True
b. False: skinfold measurements can be used to estimate body fat percentage based on the assumption that the amount of subcutaneous fat is proportional to the total amount of body fat.

Answers

The answer to the question you asked 
 is true
Final answer:

Skinfold measurements can accurately estimate a person's body fat percentage by assuming the amount of subcutaneous fat (under the skin) is proportional to the total body fat. Calipers measure skinfold thickness at several body locations, and these measurements are used in equations to estimate body fat.

Explanation:

The statement is indeed true. Skinfold measurements are widely used to estimate a person's body fat percentage. This technique assumes that the amount of fat stored subcutaneously, or directly under the skin, reflects the total amount of body fat. These measurements aid in the calculation of body fat composition, which is crucial in determining individual health status or fitness level. Special calipers are used to measure the thickness of the skinfolds at specific sites on the body. These values are then inputted into an equation to estimate body fat percentage.
