Explanation:
1.In this environment, which trait is adaptive for the birds
2. Did the birds choose to have the adaptive trait? (yes or no)
3.Sherman suggests that reproduction always creates individuals with adaptive traits. Does this seem correct? Why or why not?
Answer:
1.Natural selection is the mode of evolution that makes living things well-suited (adapted) to their environments. This mechanism has sculpted the beaks, feet, and plumage of birds over millions of years, making these animals more successful in their environments.
2.yes
3.

Write a paragraph on why food needs to be digested. :)
Please hurry I need it.
Answer: You die if no digest
Explanation:
Food needs to be digested because your body can't contain large stuff whole, so it has to be converted into a smaller amount. For Instance, if you were to eat a entire turkey then your body would just explode I guess if you wouldn't digest it. Also, without digesting food you can't enter new food into your body. Therefore, this is why food needs to be digested.

Write a paragraph (5-8 complete sentences) using the prompt below:
An ecosystem has many living and nonliving things. Choose one producer, one consumer, and one decomposer. Explain how they work together.
Answer:
The producer is a plant. It produces vegetables and fruits for the consumer to eat. The consumer is an human. It eats the fruits and vegetables that came from the plant. Lastly the decomposer would be for example fungi. It breaks down dead plants and tree trunks. It helps the producer produce and the consumer comsume.

The equator is at a latitude of 0°. Which latitude will have the warmest temperature?
Answer:
There is a relationship between latitude and temperature around the world, as temperatures are typically warmer approaching the Equator and cooler approaching the Poles. There are variations, though, as other factors such as elevation, ocean currents, and precipitation affect climate patterns.

--------------im just trying to fill space for the minimum 20 char
The answer is probably tt
Well for parent 1 and parent 2 ( 1st parent of 2 ), parent 1 shows T so it forms Tt
Parent 1 and 2 ( 2nd parent of 2 ) ( parent 1 also has T and parent 2 has t ) so it forms Tt
Parent 1 ( 2nd parent of 1 ) and parent 2 has t and parent 1 is normal which forms tt
So that leaves 2nd parent 1 and parent 2

Do you think that photochemical smog levels are high during the winter or during the summer? Explain.
Answer:
Use this: I think the photochemical smog levels are higher during the summer do to the increase in car usage and pollution. Studies show that more people use cars in the summer. In addition, the hot, musty, humid air in the summer can significantly increase pollution effect.
Explanation:
Find the average kinetic energy of the molecules shown in the sample above. ( C and D are wrong )
a. 5
b. 4
c. 3
d. 36
Answer: B
Explanation:
A student uses a lever and fulcrum to lift a rock off the ground.
Which option describes when potential energy is converted into kinetic energy during this process?
a. when the lever is wedged beneath the rock but before it has been lifted
b. when the student presses down on one side of the lever to cause it to move
c. when the rock rests on the ground without the lever
d. when the rock rests above the ground
Answer:B
Explanation: I know this because kinetic energy is when something is moving and potential energy is when something is not moving and the energy is being stored so it has you are pushing on the other side moving the object it is transforming the potential energy also known as stored energy into movement also known as kinetic energy

Answer:
Disease can reduce the size of a population quickly.
The amount of resources, such as food and water, limit how many pikas can survive.
The presence of predators limits how large the population can grow.
As the population grows, the pikas compete with each other for resources.
The amount and types of space avalible in an environment mean only a certain number of pikas can make homes.
Answer the following questions with a picture only PLEASEEEEE.
1. What is the main source of energy for ecosystems?
2. What are some natural things that can disturb ecosystems?
Answer:
1.Photosynthesis is the process of converting light into energy
2.Natural events, such as wind, drought, flood, fire, or disease.
Explanation:
1.Since photosynthesis converts light into C-H bonds in organic material, photosynthesis is the most common source of energy in most habitats, and therefore carbon flow and destiny are inextricably related to energy flow.
2.Natural disasters such as wind, drought, storm, burning, or disease may cause disruption. These "natural occurrences" are often linked to human activities. Air and water emissions, as well as climate change effects such as temperature, rainfall, and ocean chemistry, are also examples of human disruptions.

Answer: The wind erodes the earth by moving pieces of it every which way.
Explanation:
Every patch of air carries hundreds of thousands pieces of dirt sand and chunks of earth. When the wind changes course it will slowly pick up more and more and until an indent will form. This is also how sand dunes are made.
Answer:
If the wind constantly pushes a rock, eventually the sides will start eroding, and the wind will cause it to break and erode.
The blowing wind constantly changes the earths surface by moving rocks, and breaking them.
by the wind constantly pushing sand on top of each other in one place.
