Answer:
Digestive system and circulatory system
Explanation:
The digestive system breaks food down into nutrients such as glucose. Now the circulatory system enters the picture. It transports glucose and other nutrients from the digestive system to the cells. The circulatory system also transports oxygen from the lungs to the cells.
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.
Knowledge BoosteR :
As per newton's second law of motion, force is measured as the rate of change of linear momentum.
Formula : F = dp / dt

Answer: its a
Explanation:
You find an organism growing on a dead log and after careful study, you determine that it is multicellular, heterotrophic, and its cells have cell walls. Given this information, you classify this organism into which kingdom
Answer: This is a plant organism due to it having cell walls but to be specific this is classified as being in the fungi Kingdom such as mushrooms.
Fungus grow on decaying or dead organisms to help break them down Hope this helps ^_^
Answer:
It is in the plant kingdom :) :)
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.

What do pesticides, heavy metals, hazardous waste, mining for metals, mining for ores, all have in common?
Answer:
pollution of land and water
Explanation:
Pesticides, heavy metals hazardous waste and mining for metals or ores all cause land pollution.
These contaminate the land kill the useful microbes present in the soil. Moreover, when used excessively these chemical enter in our food chain and through into our body and cause various disease. Minamata disease in japan is one such example cause be mercury contamination.
These cause water pollution too. Chemical waste in water give rise to eutrophication and leaching.

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.
What 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.
What "gem" is formed as a result of the Carbon Cycle
Answer: Diamonds Form from Fluids in the Mantle That Migrate Due to Plate Tectonics. Diamond is a metasomatic mineral that forms during migration of carbon-bearing fluids, which means that it forms from fluids and melts that move through the mantle.

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.

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
Explanation:
What is your opinion on climate change? Do you believe it is the naturally occurring fluctuations of Earth's temperature? OR Do you believe it is being caused by human activity?
