Birds are the main predators of these beetles; they hunt the beetles by sight and pick them up off of the tree bark where they feed. A logging company clears the trees off of the island and plants younger trees as a replacement. Trees with light bark are planted on one side of the island and trees with dark bark are planted on the other side of the island. What do you predict would happen to the range of coloration in the populations of beetles on each side of the island?
Select TWO answers, one to represent the beetles living on the light colored trees and one to represent the beetles living on the dark colored trees. (2 points)
A. graph 2 below
B. graph 3 below
C. graph 4 below
D. graph 5 below
Answer:
B. graph 3 below
D. graph 5 below
Explanation:
The original population of beetles (Graph 1) shows that most individuals had an intermediate phenotype between dark and light color. The graph expresses its highest point in the middle of the phenotypic ax, while the curve´s tails coincide with light and dark colors.
Probably, most of the trees inhabiting the whole island had some darkish color tone, which beetles used to camouflage and avoid predation.
When the company cleared the area and reforested, they planted light trees on one half and dark trees on the other half of the island. This change in the environment modeled the beetled phenotype, together with predation pressure.
If we consider the whole original population, we should say that it went under a disruptive selection. But if we think about the sides of the island separately, we could say that the population living on each side went under directional selection. We are not thinking about the whole population of beetled inhabiting the whole island, but two groups inhabiting each side of the island.
Graph 3 represents the beetles inhabiting the part of the land with dark trees. The population went under directional selection, and most of them turned into dark-colored to camouflage with the substrate in which they live.Graph 5 represents the beetles inhabiting the other part of the land with light trees. The population went under directional selection, and most of them became light-colored to camouflage with the substrate in which they live.

Select one:
Shivering by the muscles when temperature drops.
The attraction of platelets when a wound occurs.
Sweating due to an increase in body temperature.
The reduction of hormone production during pregnancy.
Answers
Answer:
2
Explanation:
The attraction of platelets when a wound occurs indicates a positive feedback. The correct option is B.
What is feedback mechanism?The feedback mechanism is the body's mechanism for keeping hormone levels within desired limits.
The feedback mechanism is activated by an increase or decrease in hormone levels. The body has two types of feedback mechanisms: positive feedback mechanisms and negative feedback mechanisms.
Positive feedback loops and negative feedback loops are the two types of feedback loops.
Positive feedback increases system output, causing growth or decline. Negative feedback dampens output and helps to keep the system stable around an equilibrium point.
Platelet plug formation is thought to be a positive feedback process because ADP and VWF levels rise as more platelets activate to form the plug.
Thus, the correct option is B.

Answers
Answer:
isolation is a significant factor in adaptation and speciation
Explanation:
In the theory of evolution by natural selection proposed by Darwin, adaptation refers to the adjustment of organisms to their environments in order to increase their chances of survival in that environment. In the Galapagos Islands, Darwin observed that finches had different types of beaks adapted to the type of food they ate. From this observation, Darwin proposed that finches evolved to eat different food sources. In this case, the islands lead to an adjustment (evolutionary) process by which geographically isolated individuals accumulate genetic differences in order to adapt them to the environmental conditions in the islands, which then may also prevent breeding between individuals from different islands when they are reunited (i.e., it may also lead to speciation).

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?
Answers
the trophic pyramid is the reason
what the trophic pyramid is: Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers
- predators get little energy from the prey they eat so they must consume multiple prey
It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.
The trophic levels of food chainThe food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.
Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.
The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.
The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.
Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

"Skeletal muscle, also called voluntary muscle, in vertebrates, most common of the three types of muscle in the body. Skeletal muscles are attached to bones by tendons, and they produce all the movements of body parts in relation to each other. Unlike smooth muscle and cardiac muscle, skeletal muscle is under voluntary control. Similar to cardiac muscle, however, skeletal muscle is striated; its long, thin, multinucleated fibres are crossed with a regular pattern of fine red and white lines, giving the muscle a distinctive appearance. Skeletal muscle fibres are bound together by connective tissue and communicate with nerves and blood vessels."

Explain the advantages to a plant of having its cell membranes surrounded by cell walls
Answers
Answer:
Advantage of cell walls
It protect and support the cell .
To give difinite shape for the cell.
Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.
The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:
Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.
Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.
Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.
Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.
Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.
