Answer:

"Anything that looks like a snake should produce the instinctive fear response," Slobodchikoff said. “Cucumbers are shaped more like snakes, with their curving sides, than ears of corn or eggplants, so they produce a greater response."

But don't go trying to prank your cat with cucumber-shaped objects just yet. Scaring cats can have long-term effects on their mental health.

"Anytime you scare an animal, you risk inflicting psychological damage, so that the animal will be afraid not only of cucumbers,” Slobchikoff said, “but also the surroundings in which the cucumber was presented to the animal.”

Knowing that some individuals from Island 1 colonized Island 2, biologists sample the Mainland and two Island populations fifty years after the colonization events. They determine that allele frequencies are similar on both islands, but they are significantly different than the frequencies of the mainland population. Which of the evolutionary mechanisms could be used to explain these observed

Answers

Answer:

The evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect.

Explanation:

Genetic drift is the random change that occurs in the allelic frequency of a population through generations. The magnitude of this change is inversely related to the size of the original population. These changes produced by genetic drift accumulate in time and eventually, some alleles get lost, while some others might set. Genetic drift affects a population and reduces its size dramatically due to a disaster -bottleneck effect- or because of a population split -founder effect-. In founder effect, a new population originates when a few individuals who are coming from a bigger population carrying its genes, settle down in a new area and reproduce. This small population might or might not be genetically representative of the original one. Some rare alleles might be exceeded or might be completely lost. Consequently, when the small population increases in size, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and there exists the possibility of developing a peculiar allelic composition. If the number of individuals that originated the new population is low, the founder effect will be very extreme, because the effects of the genetic drift are inversely proportional to the original number of individuals.  

In the exposed situation, the evolutionary mechanism that could be influencing the allele frequencies between both islands and the mainland population might be Founder Effect. The fact that both islands are similar in their frequencies might be due to little genetic variation on island 1, or because dispersion to island 2 is a recent event on time.

How does a tree grow? Explain in detail

Answers

Answer:

Trees grow in height as a result of meristems that are located at their branch tips. These meristems are called apical meristems. ... The vascular cambium produces new xylem and phloem each year and as a result, the trunk, branches, and roots continue to increase in diameter.

Explanation:

hope this helps have a good rest of your day :) ❤

Answer:

in botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world.

Myoglobin transfers oxygen obtained from hemoglobin to mitochondrial proteins involved in the catabolism of metabolic fuels to produce energy for the muscle cell. What can you conclude about the structures of these mitochondrial proteins?

Answers

Answer:

Explanation:

Mitochondria is a double membrane bound organelle that is located in most eukaryotic organisms and it has a number of different shapes.

A mitochondrion has a outer and inner membranes made up of phospholipid bilayers and proteins which have different properties. Because of the double membraned organization, mitochondria have five distinct parts:

Outer mitochondrial membrane

Intermembrane space which is the space between the outer and inner membranes

Inner mitochondrial membrane,

the cristae space which is formed by the folding in of the inner membrane and

matrix which is the space within the inner membrane.

Mitochondria has a complex structure that allows for all the activities carried out by it this includes,Energy conversion, Pyruvate and the citric acid cycle, NADH and FADH2 which are the electron transport chain, Heat production and Storage of calcium.

Answer:

B. What happens to the materials that make up a living organism after it dies.

Explanation:

An ecosystem can be defined as the natural living habitats of both living and non-living organisms.

Ecosystem services such as plant pollination, nutrient cycling and water purification are essential services that are being provided by the ecosystem. These services are really very vital, important and useful for the sustenance of life, both for humans, plants and animals because they enhance social welfare.

In this scenario, Haley knows that plants and animals are made up of many different materials. She wants to know how these materials can cycle through an ecosystem. Therefore, the question Haley could ask to learn more about this topic is; what happens to the materials that make up a living organism after it dies?

Basically, the material that make up a living organism decomposes after it dies and are then used up as nutrients by plants growing on the soil.
