combustible ....................
Statements 1 and 4 are true, while 2 and 3 are false.
<h3>Decomposition reaction</h3>
In decomposition reactions, one or more reactants decompose to produce two or more products.
Decomposition reactions with single reactants are known as single decomposition reactions. Those with 2 reactants are known as double decomposition reactions.
Decomposition reactions do not always produce elements. It could be compounds in some cases.
Decomposition reactions always obey the law of conservation.

#SPJ1
Energy from the sun reaches Earth by way of radiation.
The sun cannot conduct heat to the Earth directly because the two bodies are not in contact with each other. Convection is also impossible, as no medium connects the two bodies to facilitate heat flow. Instead, the sun radiates much of its energy as light of various wavelengths. Some of this radiated light is in the infrared part of the spectrum and reaches Earth as heat.
Light in the visible part of the spectrum also has the effect of warming the Earth. It does this by penetrating the atmosphere and being absorbed by the land and water. Once the Earth has absorbed all of the energy it can hold, it begins to radiate energy back toward space. This terrestrial radiation is primarily in the infrared band of the spectrum, which is absorbed by aerosols in the atmosphere. These greenhouse gases trap heat and store up the surplus energy of the Earth's allotment of solar radiation. Eventually, even the atmosphere reaches thermal saturation and radiates waste energy back out into space.
I hope this helps :)
False.
Chromosomes carry genetic codes, not proteins :)
Answer:
Low,cell,increase,decrease,volume,pressure,Renin,negative
Explanation:
It is synthesized when blood pressure is low or cell division is activated.It causes increase in resistance and decrease in fluid output(which helps to maintain blood volume and blood pressure) and an increase in blood volume(if fluid intake occurs). Consequently,blood pressure increases.This is aided by the release of both renin and aldosterone.As the blood pressure returns within its normal homeostatic levels,both renin release and angiotensin 2 synthesis are decreased by negative feedback.
