In the gradualism model, species change _____ over time. Evidence for intermediate changes in species' characteristics is_____ . In the punctuated equilibrium model, changes can be rapid followed by periods ______of change. Evidence for intermediate changes in species' characteristics is _____
Answer:
In the gradualism model, species change slowly over time.
Evidence for intermediate changes in species' characteristics is anagenesis.
In the punctuated equilibrium model, changes can be rapid followed by periods of steady change.
Explanation:
Gradualism theory states that the evolutionary processes imply slow, uniform and gradual transformations. This type of evolutionary theory is referred to as anagenesis, where branches are not observed during the evolution of populations. On the other hand, the punctuated equilibrium theorizes that the evolutionary processes are characterized by sudden modifications that are followed by periods without changes. It is likely that both processes may drive evolution of species.
Answer:
gradually, present, little, absent.

process of fertilized eggs
Answer:
Explanation:
Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.
In the darkness, a pinpoint of light becomes visible. Someone has turned on a flashlight. The pinpoint grows to the size of the bulb. Because this is slow motion, only the bulb is bright. Nothing else lights up—yet.
Now the light begins to spread outward from the bulb. It fills a bigger and bigger space. As the light moves forward, it strikes little fog droplets, the ground, a sneaker, a tree, a cat. After each collision, some light bounces off. It is redirected. Some of it reaches a person's eyes. Only then can the light trigger the person's eyes and brain. In slow, stretched-out speech, the person says, "L000000-000000k! Aaaaaaaaaaaa caaaaaa-aaat!"

Answer:
"The cricket population would increase"
Explanation:
Without mice as a natural predator, there would be no regulation as to how many crickets live in an area, thus there would be an excessive amount of breeding which can lead to mutations and more sick crickets than healthy ones. The mice pick off the sick/ slower ones so the naturally stronger crickets can pass on their genes to future generations.
Answer:
The cricket population would increase.
Explanation:
If there were no more mice to eat the crickets, the crickets would have a larger population.

Explanation:
Red squirrels and gray squirrels have been the native species on an island for many years. A few years ago, black squirrels entered this island. The black squirrel is an invasive species. Invasive species aren't native to the ecosystem. They move into an ecosystem because of natural changes or human intervention. Red squirrels and black squirrels have identical food requirements, but gray squirrels have a different diet. What three effects will these events have on the island's squirrel population?
Answer:
1. There will be direct predation of species.
2. There will be competition for limited resources like breeding sites, prey.
3. Transmission of diseases or they can cause danger to the native species.
Explanation:
Invasive species are species of organisms that are not natural to an ecosystem and move to an ecosystem because of natural changes and human intervention. Islands are prone to the invasion of invasive species because they don't have predators and there is no competition that control populations in their ecosystem. The invasion of black squirrels will lead to competition for limited resources like breeding sites or prey, the black squirrels will begin to predate other squirrels because they have different nutrients requirements and they can transmit diseases to other squirrels if they are carrier.

explain the difference between weathering and erosion? how is deposition also involved in this three step cycle?
Answer:
Erosion is the process by which natural forces move weathered rock and soil from one place to another. ... Deposition occurs when the agents (wind or water) of erosion lay down sediment. Deposition changes the shape of the land. Erosion, weathering, and deposition are at work everywhere on Earth

True or false? To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is required.
Answer: Energy can not be lost, rather it can be converted into other forms of energy , so false.
Explanation:
To make up for the loss of energy when solar energy is used by primary producers and then transferred up the food chain, a continuous supply of solar energy to the ecosystem is not required. Thus, the given statement is false.
What is energy cycle in an ecosystem?The energy flow in the ecosystem is important to maintain an ecological balance in the ecosystem. The producers in a food chain synthesize food by the process of photosynthesis. A part of this energy is stored within the plant species.
The energy cycle in an ecosystem is based on the flow of energy through the ecosystem. The energy from sunlight is converted by the plants them into the growing new plant materials including the flowers, fruits, branches, trunks, and roots of the plants. Since, the plants can grow by converting solar energy directly into their tissues.

Explain how the digestive and circulatory systems interact.
Answer:
Explanation:
Both systems interact in the sense that digestive system involves the breaking down of complex food substances into simpler absorbable forms. These absorbable forms like glucose , amino acids etc are assimilated into the circulatory system through the hair-like structures in the small intestine (Villi, which has lots of blood capillaries) into the circulatory system. The circulatory system transports these food materials to different parts of the body where they are need for energy production and other metabolic activities.
