Could the blue jays ever have had thin beaks? (PLEASE ANSWER ASAP!! I WILL AWARD BRAINLIEST) (image below)
1. No blue jays could have been born with a thin-beak trait because none of the adult blue jays had that trait to pass down.
2. No blue jays could have been born with a thin-beak trait in the past, but some with that trait could be born in the future if the environment changes to have pine cones with seeds.
3. A blue jay could have been born with a mutation in its genes for the thin-beak trait and lived for a little while, but it would have been more likely to die before it had offspring.
4. A blue jay could have been born with a mutation in its genes for the thin-beak trait, but having a mutation in its genes would have caused it to die when it was born.
Answer:
i believe the answer is 2)
Explanation:
because birds that eat seeds need to have thinner beaks in order to get to the seed. seeing as how their beaks are currently too large for that, they wouldn't be able to reach the seeds- they would have to adapt to the new environment **if that were to happen**
good luck :)
hopefully, this helps

How does high altitude affect breathing? please help
Per my research, it was said that the higher the elevation, the more difficult breathing becomes. The air at higher altitudes is colder, less dense, and contains fewer oxygen molecules, which means that you would need to take more breaths in order to get the same amount of oxygen as you would at lower altitudes.
Explanation:Hope this helped and please correct me if I am wrong. I did my research and I think this is right because of the elevation. Have a good one!

Describe the similarities you observe between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants
Help me please
The primary mode of reproduction that separates flowering plants from non-flowering plants. While non-flowering plants need on dispersion to continue their life cycle, flowering plants depend on pollination for reproduction.
What is flowering plants and non-flowering plants?Seeds that are protected by a flower or fruit are used by flowering plants to reproduce.
Conifers, ferns, and mosses are examples of non-flowering plants. Conifers produce seeds in cones to reproduce. Spores are used in fern and moss reproduction.
The reproductive organs of plants, called flowers, transport both male and female gametes.
These flowers bear fruits once fertilised. Non-flowering plants are ones that reproduce by spores but don't produce flowers.
Plants differ in appearance, but they always share three characteristics: they are multicellular; they can produce their own food; and they are green.
Thus, these are some similarities between the major stages in the life cycles of flowering plants and non-flowering, seed-bearing plants.

is a baseball player getting ready to throw a baseball kinetic or potential energy? support your answer with 5 sentences
Answer:
kinetic is the awnser
when an object is gaining forice it kenetic
Answer:
Potential
Explanation:
Potential energy is when you store up energy.
Kinetic, is when you use that stored up energy to move something (or try to).
In this case, the baseball player is storing up energy to through the baseball.
If the sentence was a baseball player threw the baseball, then it would be kinetic.
Because the baseball player is not moving the ball, it's potential energy.

Byron goes rafting on the Colorado River. As he paddles along, he can see the erosion, weathering, and deposition caused by the river. Explain how a river is responsible for causing erosion, weathering, and deposition. Give an example of each.
P.s. no links or you will be reported
Answer:
Erosion by a river is caused by its capacity to curve out rocks and carry soil particles as sediments due to its erosion power. Rivers carve out rocks to form the pebbles you see in a river and also the rapids and cataracts.
A river contributes to the weathering of rocks such as limestone rocks. The water dissolves the calcium carbonate minerals in the limestone rocks making it brittle and easily crumble. Water also causes ferrous rocks to easily crumble due to turning of the iron minerals into rust.
rivers deposit their sediments when their velocity decreases. Deposits by rivers cause features like oxbow lakes and deltas that are observed at the mouth of rivers, where the slope gradient is very low.
