Explanation:
A group of scientists wanted to investigate how populations of organisms can change over time. They decided to study a population of birds on the Galapagos Islands exposed to extreme conditions of drought.
Which of the following would be the best hypothesis to test how the birds might adapt to these conditions over time?
A.Birds exposed to extreme drought will become less attractive over time.
B.Extreme drought conditions could cause bird species to become extinct.
C.If birds are exposed to extreme drought then their beak size will quickly change overnight.
D.Birds might breed with other species and adapt to these conditions.
Answer:
I Dont think it would be D. Breeding with other species is possible, but extremely rare. I Think its most likely C, because C shows an adaptation, their beak changing in size. They might be changing so that their beaks are strong enough to break through plants or ground and drink the water from it. There might also be other reasons, that is just my prediction. If it gets too harsh, however, there might not be a way to adapt to it and they may go extinct. But as i said i think it would be C.

Were does all the energy start from ALL the organisms
Answer:
The sun
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
Answer:
from sun all the energy starts from All the organisms it is the fact that scientist had proven itdescribe and explain experiences/connections from outside of school related to our learning goal: I can use characteristics to organize Bacteria, Archaea, and Eukaryote.
Answer:
Explanation: An experience I had outside of school related to biology is; I was at the park a long time ago, when i noticed something in the ground, it was a fossil of a bird and it was engraved inside of the concrete.
compare the circulatory system of a plant and animal
plz help do not copy off anything because this is a unit test
Answer:
The circulatory system is the method of transport in plants and animals. Animals must have nutrients and oxygen reach every cell in their body. Plants must have nutrients and carbon dioxide reach every cell in their “body.” Both plants and animals must also have waste products removed from their systems.
Explanation:
You are gonna have to change the wording a little but thats ok! An y'know what? I have the same answer on one of my past test we did like a week ago!
Answer:
In plants, there is a conducting tissue that is located in the veins. Inside, there are xylem cells that conduct water and minerals upward from roots to leaves and phloem that conducts food. Plants have only water solutions flowing through the tubing. Animals can have one of two kinds of circulatory systems: open or closed. In animals, each blood vessel in the network is responsible for transporting nutrients and oxygen to cells and for removing wastes and carbon dioxide from cells.

Komodo Dragon
Hammerhead Shark
Honey Bees
Jellyfish
here is the page of my question 100 points!!
Answer:
Parthenogenesis. Parthenogenesis is a form of asexual reproduction in which an egg develops into an individual without being fertilized. ... Two female Komodo dragons, a hammerhead shark, and a blacktop shark have produced parthenogenetic young when the females have been isolated from males.
Explanation:
Asexually produced offspring are genetically
1. identical to the parent
2. different from the parent
3. different from each other
4. formed by two parents
1. identical to the parent
