Two-thirds of an ant colony is crushed by an elephant herd. The population before the crushing was 50% red and 50% black, and after the crushing, it was 70% red and 30% black. Is this evolution and, if so, what mechanism of evolution occurred? *

Answers

Answer 1
Depends, this shows that there can be the presumption that fire black ants are more aggressive and tried to fend off their ant colony while the red ants could be more conservative towards aggression.

Temperate climate zone is most likely to experiences the greatest variety of weather. Therefore, option (C) is correct.  Whereas low humidity, freezing temperature and light clouds (B) result in snow.

What are climatic zones?

Climate zones are regions that have their own unique climates. It is possible that the weather patterns, latitude, or groups of flora and animals correspond to these zones. There are a variety of climate categorization schemes, each of which defines zones based on a different combination of climatic elements or factors taken individually.

On Earth, there are approximately five primary types of climates, including tropical, dry, temperate, Continental and Polar.

Explain why a food web is a better illustration of an ecosystem than a food chain

Answers

Answer:

In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain. Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.

Explanation:

Food webs are more complex than food chains. Food webs show multiple organisms that predators eat while food chains don’t. If you need me to explain more I will! Hope I helped :)

Energy in Ecosystems
Plants capture the sun's energy and make food in the process of photosynthesis. Only about 0.1 percent of the sun's energy is captured by plants. Plants take carbon dioxide and water and, using the energy from sunlight, convert it into glucose (food) and oxygen. About one-half of the energy absorbed by plants is used right away. The other half is stored in plants as energy-containing food (carbohydrates).

describe how wind forms ocean waves in deep water and how these waves change as they develop in 6 sentences
PLEASE HELP

Answers

Wind-driven waves are created by friction between wind and surface water. When wind blows across the surface of an ocean the continual disturbance creates a wave crest. These waves can be created through local winds or distant winds. The waves can be affected by wind speed and wind duration. The faster the wind and the longer it blows, the bigger the waves. It also can depend on how far the wind blows uninterrupted.

I hope this helps :)
Wind forms ocean waves by creating friction between the wind and surface water. This creates a rising crest that forms into a wave. As the wind continues to blow, the waves also continue. Depending on the location, the waves change. For example, when deep water waves move to shallower waters, they change into breaking waves. As the wave travels into deeper waters, it slows down and the wavelength decreases.

Explanation:

Mitosis consists of specific phases that occur in a specific order. (PMAT!)

Prophase is the first phase of mitosis where chromosomes condense and become visible.  

Metaphase involves chromosomes moving to the center of the cell.  

Anaphase is where the chromosomes are equally pulled to either side of the cell.  

Telophase is where the chromosomes bunch up at either end of the cell and begin to unravel into their previous state.  

Cytokinesis then occurs where the whole cell divides between the newly forming nuclei.

What do you predict might happen if someone introduced a new species that could eat large amounts of algae at a rapid pace, outcompeting other species already present? Describe what you think might happen, making sure to specify how at least three of the organisms that might be affected and giving a detailed explanation for each organism. Make sure to include in your answer at least one organism that does not eat algae.

Answers

Answer:

Small fish, crustaceans, and water-dwelling insects eat algae, so they are going to be affected if an new species is introduced and is water based, also the new species its the algae at a rapid pace, a bunch of organisms will be in danger because some of the organisms eats algae as a primary source of food. If there is something that can make this species go extinct for sometime until it is possible algae can grow as fast as they eat it, then there would be a bunch of sea creatures/organisms affected by this huge change. Not only will the small fish, and other sea creatures/organisms will be affected but it'll also disrupt the ocean food chain, including us human! Because we eat fish, some people depend on algae because if the algae kept getting ate up by this "new" species EVERYTHING else would be also disrupted. Microscopic animals wouldn't have enough food, fish wouldn't have enough oxygen and plants would lose some of the carbon dioxide they need to grow, so these organisms DEPEND on algae for their LIFE!

4. membrane

5. make greater

Answers

Answer:

middle ear- hammer, anvil, stirrup

cochlea- cavern-like bone with tiny hairs and fluid

eardrum- membrane

outer ear- gathers sound

amplify- make greater

The correct match is gathers sound - outer ear, hammer, anvil, stirrup - middle ear, cavern-like bone with tiny hairs and fluid - cochlea, membrane - eardrum, and make greater - amplify.

The outer ear is the visible part of the ear and includes the pinna (the external ear flap) and the ear canal. Its primary function is to gather sound waves from the environment and direct them into the ear canal. The middle ear is a small, air-filled chamber located between the outer ear and the inner ear. It contains three tiny bones known as the ossicles: the malleus (hammer), the incus (anvil), and the stapes (stirrup). The cochlea is a spiral-shaped, snail-shell-like structure located in the inner ear. It is filled with fluid and contains thousands of tiny hair cells along its walls. The eardrum, also known as the tympanic membrane, is a thin, semitransparent membrane located at the end of the ear canal in the outer ear. Amplify means to increase the magnitude or strength of something. In the context of hearing, the middle ear's ossicles (hammer, anvil, and stirrup) play a crucial role in amplifying the sound vibrations that reach the eardrum.
