Why do disruptive selection pressures tend to favor rapid evolutionary changes?
a. They result in sudden gene frequency changes.
b. They eliminate extreme genetic traits.
c. They select for one variation of a genetic trait.
d. They result in environmental adaptation.
Answers
Answer:
The correct answer is a. They result in sudden gene frequency changes.
Explanation:
The evolution of life, its diversity, is reduced to the processes of microevolution or speciation. But not all evolutionary processes in populations end with the formation of a new species. Disruptive selection is a type of natural selection that selects against the average individual in a population. The composition of this type of population would show phenotypes (individuals with groups of traits) of both extremes but with very few individuals in between. Disruptive selection tends to increase intra-population variability and, to this end, favors individuals at both ends of the phenotypic distribution, that is, as a final result there is a break in two different populations, which can lead to speciation.

A"They result in sudden gene frequency changes."Explanation:

Explain how an organ and organelles are related
Answers
Answer:
Just as organs are separate body parts that perform certain functions in the human body, organelles are microscopic sub-units that perform specific functions within individual cells. Organelles are specialized structures that perform various jobs inside cells.
Organelles are microscopic subunits that carry out certain tasks within individual cells, whereas organs are distinct body sections that carry out specialized tasks for the human body.
What is the relation between organ and organelles?Literally, the phrase refers to “tiny organs.” Organelles provide specialized functions to keep a cell alive, much like organs like the heart, liver, stomach, and kidneys serve specific functions to keep an individual alive.
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization in the body, going from the simplest to the most complex.
Like an organ in the body, an organelle is a subcellular structure that performs one or more particular functions for the cell.
Therefore, organ and organelles differ in their functioning.

Gravitational force multiple choice

Answer:
Option B. The force would be quartered (factor of 1/4).
Explanation:
The gravitational force between two objects can be expressed with the equation:
By analyzing the equation, we can see that if we multiply both m1 and m2 by 1/2, the resulting new F would be lower by a factor of 1/4 (as 1/2 times 1/2 equals 1/4).
Thus the correct answer is option B.
Please help worth 95 points. Project: Algae Cultures: Directions
In this report, you will be researching the different types of algae. Report on one algae from each of the three categories (blue-green, green, and green-brown). Include the following information: Name of the algae, Category if falls under, Where it is mostly found and what conditions it needs to survive, Whether it is unicellular or multicellular, Where in the food chain algae are, and what predators it may have, Research why some scientists think algae should be classified plants, and explain the debate.
1.Which organisms did you identify 2. How easy or difficult was it to find an example of each category? Which one was the hardest to find? Why? 3. Which environments were most common to find algae in? Why do you think so? 4. What part of the food chain is the alga? 5. Why is algae classified in the Protist Kingdom and not the Plant Kingdom even though they are photosynthetic? Research why scientists feel they should be classified as plants.
Answers
Answer:
1) I identified the Golden-Brown Algae.
2) It was very easy to find the category because of the solid color base and because it only had the daitoms. It did not have multiple like the Green Algae and the Blue-Green Algae.
3) In fresh, brackish or salt water. They are found both in tropical lakes and seas, and in the alpine and polar snows. They are unicellular or multicellular protist plant organisms, whose cells do not form tissues and lack flowers. They are considered the first link in the food chain in the aquatic environment. They are found in fresh, brackish or salt water. They are primary producers in the food chain, capable of producing organic substances through photosynthesis, so they use sunlight. They are found in tropical lakes and seas up to the alpine and polar snows.
4) Producer Alga is A plant and produces food for other organisms.
5) Algae (Euglena) do photosynthesis as plants do. They also move around and eat, as do animals. But they are unicellular. In order to be classified as a plant or animal, an organism has to be multicellular, made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls while algae does't have one, so it is a protozoan. Algae resemble the protozoa, so they are put into the Protist Kingdom.
Explanation:
I had the project.
Algae recreate a major part of the marine ecosystem because they exist as the decomposers current in the marine ecosystem; any harm to them could cause an inequality in the whole marine ecosystem.
What are golden-brown algae?1)The Chrysophyceae, usually named chrysophytes, cryptomonads, golden-brown algae or golden algae exist as an extensive set of algae, seen mainly in freshwater.
2) It stood very easy to see the class because of the solid color base and because it only contained the diatoms. It did not contain multiple like the Green Algae and the Blue-Green Algae.
3) In fresh, saline, or salt water. They exist seen both in tropical lakes and seas and in the alpine and polar snows. They exist as unicellular or multicellular protist plant organisms, whose cells do not constitute tissues and absent flowers. They exist thought the first link in the food chain in the aquatic environment. They exist seen in fresh, brackish, or salt water. They exist as primary producers in the food chain, qualified of producing organic substances through photosynthesis, so they utilize sunlight.
4) Producer Alga exists in a plant and makes food for different organisms.
5) Algae (Euglena) accomplish photosynthesis as plants do. They even move about and eat, as do animals. But they exist unicellular. To be categorized as a plant or animal, an organism contains to be multicellular, made of better than one cell. Since it stands as a unicellular organism with some plant and animal elements, it exists named a protist. Plant cells contain walls while algae don't contain one, so it exists as a protozoan. Algae reach the protozoa, so they stand to put into the Protist Kingdom.

What is Cellular respiration?Cellular respiration is defined as the process that occurs in the mitochondria of all living organisms. In this process, both plants and animals break down simple sugars into carbon dioxide and water and release energy in the form of adenosine triphosphate (ATP).
This process is a set of metabolic reactions that occur inside cells to convert the biochemical energy obtained from food into a chemical compound called adenosine triphosphate (ATP).

2.How do you think that the one species of finch evolved into many different species, each with its own advantages?
3. In what ways do these advantages help the finches to survive and reproduce?
4. What might have happened if the finches didn't evolve into many different species?
Answers
Answer:
1. Because the drought reduced the number of seeds and finches with bigger beaks were able to eat the larger and harder seeds so more of them survived.
2. Summary: Changes in the size and form of the beak have enabled different species to utilize different food resources such as insects, seeds, nectar from cactus flowers as well as blood from iguanas, all driven by Darwinian selection
3. Medium ground finches with larger beaks could take advantage of alternate food
