How might long-term climate change affect the behavior of migratory birds that nest in the Arctic tundra?
Answer:
Climate change affects patterns of migration. Global warming also influences the routes of many migratory birds and their annual migration rhythm. A lot of migratory birds change their routes, shorten or completely cancel their journey as a result of changing temperatures.
Explanation: Hope this helps
Answer: well climate change can be many things like if it snows gets colder that means more nesting areas of it gets sunnier or hotter less nesting areas and if that happened then they would have to find different areas to nest at

thanksis this physicsi think its physicsWhat two systems interact to get oxygen to the cells
Answer:
The respiratory and circulatory system functions together to circulate oxygen and blood all through the body. The movement of air takes place in and out of the lungs via the bronchi, trachea, and bronchioles. The movement of blood takes place in and out of the lungs via the pulmonary veins and arteries, which associate with the heart.
The pulmonary arteries mediate deoxygenated blood to the lungs from the heart, and the pulmonary veins carry oxygenated blood to the heart again so that it can be distributed to the rest of the body.
A track athlete throws a 2kg discus into a field with a velocity of 21m/s. What is the momentum of the discus?
Answer:
Given :
Momentum of disc = 42 kg m/s
Velocity of disc = 21 m/s
To Find :
Mass of the disc.
Solution :
❖ Momentum is defined as the product of mass and it's velocity..
Mathematically, p = m × v
p denotes momentum
m denotes mass
v denoted velocity
➛ It is a vector quantity having both magnitude as well as direction.
➛ It can be positive, negative or zero.
➛ SI unit : kg m/s or N s
By substituting the given values;
➙ p = m × v
➙ 42 = m × 21
➙ m = 42/21
➙ m = 2 kg
∴ Mass of the object is 2 kg.

Describe the weather conditions for a Warm front.
Answer:
Explanation:
Warm fronts bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.As the front passes over an area, the clouds become lower, and rain is likely. There can be thunderstorms around the warm front if the air is unstable.

All rocks are composed of?
Answer:
Most rocks are composed of minerals. Minerals are defined by geologists as naturally occurring inorganic solids that have a crystalline structure and a distinct chemical composition. Of course, the minerals found in the Earth's rocks are produced by a variety of different arrangements of chemical elements.

WILL GIVE BRAINLISTTT!!! How can life and conditions on Earth be used as a model for life on other worlds?
Answer:
You can see the conditions of the other world, and see the composition of that world. This allows you to see what elements are abundant. Assuming there is water on that other planet, you can use the elements that are found there and see what organisms on earth are composed of those elements or use them.
Specifically, extremophiles (types of archaeabacteria) often exhibit characteristics that seem suitable for other planets. Using this, you can estimate what life on other planets have as characteristics, or even what they are made of.
Organisms with similar molecular makeups + organisms in areas with similar environmental pressures often exhibit anatomical + behavioral similarity. You can use this to model this.
The frequency of a wave does not change as it passes from one medium to another.
What will most likely happen if a light wave moves from the air into a solid?
The speed of the light wave will remain the same.
The wavelength of the light wave will increase.
The wavelength of light will remain the same.
The speed of the light wave will decrease.
Answer:
B. The speed of the light wave will decrease.
Explanation:
The frequency of the waves doesn't change as it passes one medium to another as the speed of the light wave will get decrease. Thus option D is correct.
What is wave frequency?The waves frequency is the number of waves that has fixed oint in the iven amount if time and the unit tomeausre the wave freqiency is hertz.
Where one wave equaks to one fixed point in a second. The moe energy waves have a higher fequency than thoe of the less enegy waves. Thus the speed of the light waves will get decreased.

When many individuals with the same trait die before reproducing, what happens to the distribution of that trait in the population?
Answer:
The distribution of that trait in the population will change, probably decreasing to near zero.
Explanation:
An evolutive force such as natural selection is acting on this population.
Natural selection is the result between the individual phenotype and the environment that determines the destiny of genes. It results in adaptation, which means the increase of the aptitude phenotype.
Aptitude (or fitness) is reflected by the phenotype that results in the survival, fertility, and capability of having a mate. Aptitude is the contribution of each genotype to the next generation. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.
Natural selection can act favoring an allele or against it, according to how it affects the fitness of individuals.
When many organisms in a population sharing the same trait die, this is because they did not have good fitness, so they were not adapted to the environment and its pressures. The alleles coding for that trait were not good for the fitness of the animals, so they do not get to survive.
These individuals die before reproducing, so they could not transfer their genetic charge to the following generation. Eventually, the alleles coding for the trait will decrease in the population, probably near zero. Natural selection is acting against this phenotype. Other alleles will be beneficiated, and their frequency in the population will increase.
This change in alleles frequency is what we call adaptation.
The distribution of this trait in the population will change and then the population would decrease.
What is a trait?A trait can be defined as a distinguishing quality or characteristic of a living organism. Thus, it refers to the specific features or characteristics that are possessed by a living organism.
According to genetics, traits are essentially transferred from the parents of a living organism to their offspring, so as to distinguish him or her from others.
In this context, the distribution of this trait in the population will change and then the population would decrease when many living organisms (individuals) with the same trait die before reproducing.

Which of the following describes a common role played by animals in the carbon cycle?
Dissolve and store carbon for long periods of time
Take carbon from the atmosphere to use to make food
Release carbon into the atmosphere through respiration
Break down carbon stored in rocks through the process of weathering
Answer:
Release carbon into the atmosphere through respiration
Explanation:
During cellular respiration the molecule takes in oxygen and glucose. ... Pyruvate is transported into the mitochondria and loses carbon dioxide to form a two-carbon molecule.
Answer:
Release carbon into the atmosphere through respiration
Explanation:
then that carbon is used by plants to create oxygen and the cycle repeats.
