Answer: The environment changed suddenly from a shallow ocean setting to a river system.
Explanation: Changes seen in rock layers represent changes in Earth's local history. The rock layer stack overall shows a shallow ocean setting. But the youngest layer at the top was deposited by a river. This shows the geologist that the local environment changed suddenly from an ocean setting to a river system.
Answer:
just learned about this in ap bio haha
Explanation:
Wow, that's such a cool prokaryotic cell. It looks so delicious, I wonder if I can eat it.
"Hey, cell, can I eat you?"
"No, you cannot."
"Please? I would love to have your energy-making properties!"
"How would I benefit from this? It seems like you're being parasitic."
"I would help you, by giving you protection and a safe home. You would give me energy. It seems more like an endosymbiotic relationship to me!"
"Fine, you can ingest me."
I'm so glad they let me eat them, they were so yummy. I can even create energy now, and I have a powerhouse inside me! This is so cool, maybe I should eat that other cell with photosynthetic properties.
SORRY IF THIS IS TERRIBLE I REALLY TRIED
Answer:
The role of carbon in biological systems is to allow the formation of organic molecules, in addition to providing energy for living beings.
Explanation:
Carbon is the fourth most abundant element on earth and one of the main elements of the viological systems, and its presence is essential for life on the planet to be maintained.
Carbon is necessary for all living beings, without exception. This is because it is used in the construction of organic molecules without which no living thing can survive, in addition to providing energy when it participates in sugar molecules, such as carbohydrates.
Answer:
1. Mutation- increase genetic variation
2. Selection- may increase, decrease or maintain genetic variation
3. Genetic drift- decrease genetic variation.
4. Gene flow- may increase or decrease genetic variation
Explanation:
1. A mutation refers to the changes in the DNA in an organism. The mutation of genes in DNA produces new adaptive features to evolve which increases the genetic variation of the organisms.
2. The natural selection favors the species which are best suited to live in that natural conditions. The natural selection, therefore, may increase or decrease the variation in a population.
3. Genetic drift is the phenomenon occurs due to random event which changes the gene pool of the population. When the genetic drift phenomenon is observed than the genetic variation of that population usually decreases.
4. Gene flow is the phenomenon in which the gene pool changes die to immigration and emigration. Therefore the phenomenon may increase or decrease genetic variation.
