Answer:
When you exert yourself in a strenuous workout the oxygen demands of your muscle cells quickly outpace the oxygen your body can provide. Skeletal muscle cells that have an insufficient oxygen supply to allow aerobic respiration to continue will undergo lactic acid fermentation.When you exert yourself in a strenuous workout the oxygen demands of your muscle cells quickly outpace the oxygen your body can provide.

The excretory structures of terrestrial arthropods are slender projections from the digestive tract called malpighian tubules.
What are Malpighian tubules?The malpighian tubules are channels in the digestive system of the alimentary canals present in arthropod species.
The Malpighian tubules function to provide an excretory system and osmo-regulatory system to arthropods.
These slender tubules are fundamental for the survival of many species of insects (i.e., arthropods).

In recent decades, average global temperatures have increased significantly. Scientists agree that the widespread destruction of the Amazon rain forest contributes to climate change. Which mechanism might be cited to support that hypothesis?
A Deforestation causes water on the ground to reflect sunlight.
B Deforestation reduces the number of plants able to absorb carbon dioxide.
C Photosynthesis produces energy, which gives off heat.
D Plants use up energy during cellular respiration.
[tex]\qquad\qquad\huge\underline{{\sf Answer}}♨[/tex]
The main reason causing average global temperature rise is increase in amount of green house gases like Carbodioxide, and since deforestation reduces a vast number of plants, so there is lack of plants absorbing CO2 causing this whole thing.
So, according to this the Correct choice is B
The mechanism that supports the hypothesis that the widespread destruction of the Amazon rainforest contributes to climate change is Deforestation reduces the number of plants able to absorb carbon dioxide. The correct option is B.
Forests, like the Amazon rainforest, play a crucial role in mitigating climate change because trees act as carbon sinks. They absorb carbon dioxide during photosynthesis and store it as biomass. When forests are cut down or destroyed through deforestation, the carbon stored in trees is released back into the atmosphere in the form of carbon dioxide, a greenhouse gas that contributes to global warming.
The Amazon rainforest, often referred to as the "lungs of the Earth," is particularly vital in this regard because of its vast size and high biodiversity. As large areas of the forest are cleared for logging, agriculture, and other human activities, the ability of the Amazon to absorb carbon dioxide diminishes, leading to increased greenhouse gas concentrations in the atmosphere and contributing to the warming of the planet.

Why were there no coal deposits formed during the Precambrian time? Choose the correct answer. There were no swamps with land plants. There was not yet enough carbon on Earth. There was not enough land on which coal deposits could form. There was not enough carbon dioxide in Earthâs early atmosphere
There were no coal deposits formed during the Precambrian period because there wasn't enough carbon dioxide in Earth's early atmosphere.
What is the Precambrian?The Precambrian is a Super Aeon, corresponding to the time period from the formation of the Earth (~4.6 billion years – b.a.) to the beginning of the Cambrian Period (~542 million years – m.a.).
With this information, we can conclude that there were no coal deposits formed during the Precambrian period because there wasn't enough carbon dioxide in Earth's early atmosphere.
