Answer:
Explanation:
Anatomy. Species may share similar physical features because the feature was present in a common ancestor (homologous structures).
Molecular biology. DNA and the genetic code reflect the shared ancestry of life.
Biogeography.
Fossils
Biogeographical evidence, fossil evidence, and anatomical evidence are three pieces of evidence to support the theory of evolution.
What is evolution?Evolution states the changes observed in organisms over time, this makes benefits the organism for its survival.
Anatomical evidence, support the theory of evolution, by comparing the anatomical structure of related species. Fossil evidence also provides evidence that how organisms evolve from the ancestor species.
Biogeographical evidence provides major clues about the relation between extinct and alive species, this benefits the theory of evolution. All this evidence supports the life formation around the earth and the relationship between organisms.
Therefore, biogeographical evidence, fossil evidence, and anatomical evidence support evolution.

8. For the food chain shown below, which of the following changes would 2 points
have the most severe consequences? Grasses - Crickets → Field Mice →
Hawks
A minor decrease in rainfall
The field mice population slightly increasing
The introduction of a second predator that eats field mice
0 A parasitic infestation that reduces the cricket population
Answer:
I think it is A Parasitic one
Explanation:
A decrease in rainfall may lead to drought, thereby altering the basis (first level) of the food web.
A food web is a diagram that represents the relationships between different groups of organisms in an ecosystem.Producers (e.g., plants) are organisms that maintain the entry of matter and energy to the food web.Rainfall is fundamental for maintaining the life of land producers (in this case, grasses) in the food web.In conclusion, a decrease in rainfall may lead to drought, thereby altering the basis (first level) of the food web.

You have a glass of milk and a glass of water you need to pour them into the same container such that the two liquids are differentiated and can be separated how do you do it?
Answer:
Pour the water first, freeze it, and then pour the milk. The freezing point of raw unprocessed milk is ∼−0.5 degrees Celsius, so by keeping the barrel under 0 degrees, but above −0.5 degrees, you can keep the water frozen and the milk liquid, and be able to separate them.
You can freeze the whole thing below −0.5 degrees. Just don’t warm it suddenly above 0 degrees without separating the milk first.
In fact, the freezing point of milk can be and is used as a test to check whether water was added to milk by producers.
Who came up with the theory of continental drift? Was his theory originally accepted by
the scientific community?
Answer:
scientist Alfred Wegener and no it wasn't accepted .
Explanation:
The main reason that Wegener's hypothesis was not accepted was because he suggested no mechanism for moving the continents. He thought the force of Earth's spin was sufficient to cause continents to move, but geologists knew that rocks are too strong for this to be true.

Yuki has a bowl of ice. She places the ice in a warm room and watches as it melts into liquid water. Yuki then places the liquid water over a Bunsen burner and heats it until it vaporizes. Explain what happens to the water molecules in Yuki's experiment; from the beginning to the end of the experiment.
Answer:
ice is a solid.When heat is added it turns into a liquid,its a reversible change.As regarding to the water moleculesWhen water is heated, it expands, or increases in volume. When water increases in volume, it becomes less dense. As water cools, it contracts and decreases in volume. When water decreases in volume, it becomes more dense. For samples of water that have the same mass, warmer water is less dense and colder water is more dense.Im not sure if this helps but try it out :)

Various factors influences the fluidity of the phospholipid bilayer of the cell membrane. If we were to chart the composition of cell
membranes in organisms as we move north from the equator to higher latitudes around the Arctic circle, we would expect to find
phospholipids with
A)
fewer hydrophilic heads.
B)
fewer interspersed cholesterol molecules.
both saturated and unsaturated fatty acid tails.
D
an increase in the length of the fatty acid tails.
Answer:
D
an increase in the length of the fatty acid tails.
Explanation:
As average annual temperatures decrease, we would expect to find phospholipids within the cell membranes of organisms to have both saturated
and unsaturated fatty acid tails. Saturated fatty acids tails are arranged linearly, in a way that maximizes interactions between the tails and
decreases bilayer fluidity. Unsaturated fatty acids, on the other hand, have more distance between the tails, fewer intermolecular interactions and
more membrane fluidity. Longer tails and decreased cholesterol also decrease fluidity

Explain the idea of "survival of the fittest" with regards to a population of beaver in a lake in which some have larger incisor teeth and others have small incisor teeth.
Answer:
Large teeth are used to the advantage of the beaver to make their shelter and chew through wood in order to make said shelter, so a beaver with larger teeth is more likely to have a better shelter, and therefore survive longer, reproduce more and help tip the population to have larger teeth. The opposite, however, will happen with beavers with smaller teeth. This leads to evolution.
