Before that, we need to know what causes climate change. One of the main reasons are the carbon dioxide released into the atmosphere, it traps heat but allow more heat to enter the earth, therefore climate increases over the years.
1. Set air conditioner to a higher temperature (eg. 25°C) or turn on fans instead.
Operating AC can use a lot of energy, and these energy is produced by burning if fossil fuels which releases carbon dioxide.
2. Take public transports instead of cars. The more private cars there are, the more pollutants it release, these pollutants includes carbon dioxide.
3. Turn off all the lights / electrical appliances when we leave a place. Again, electrical appliances require energy which is produced by burning of fossil fuels that gives out carbon dioxide.
4. Recycle and reuse paper that is only used on one side. Papers are extracted from trees and one main function of trees is to absorb carbon dioxide from the air. If many trees are cut, the amount of carbon dioxide in air would increase.
5. Do the laundry only if you have clothes full for the machine. If the washing machine is not full and you're starting it up, it really uses a lot of energy and water, which all again it triggers the release of carbon dioxide.
4x − 8x= −3
Step 1: Simplify both sides of the equation.
4x−8x = −3
4x + −8x= −3
(4x + −8x) = −3 (Combine Like Terms)
−4x = −3
Step 2: Divide both sides by -4.
−4x / −4
−3
- / −4
so your answer will be x= 3/4

Answer:
The four are Ll
The four will have long feathers
Explanation:
A Punnett square is a graphical representation of all possible genotypes of an offspring that is likely to arise from a particular cross or breeding event. To create a Punnett square, knowledge of the genetic composition of the parents is highly required. The two things a Punnett square can tell you are the genotypes and phenotypes of the offspring. In its simplest form, the Punnett square consists of a square divided into four quadrants. A Punnett square allows the prediction of the percentages of phenotypes in the offspring of a cross from known genotypes.
The genotypes of the four offsprings are Ll, Ll, Ll and Ll. This implies that they are all heterozygous. They will all have long feathers since the long feather (L) is dominant in all the species. In terms of phenotype, they will all have long feathers.
Answer:
C. Bent
Explanation:
Only a bent molecule is polar.
The two bond dipoles do not cancel, so the molecule is polar.
A is wrong. In a linear molecule, the bond dipoles are equal and in opposite directions, so they cancel. The bonds are polar, but the molecule is nonpolar.
B is wrong. In a trigonal planar molecule like that shown below, the resultant of the bond dipoles of the two lower bonds is equal to the upper bond dipole and in the opposite direction. The two dipoles cancel, so the molecule is nonpolar.
D is wrong. A tetrahedral molecule may have polar bonds, but it is a nonpolar molecule. The two bonds on the right have a net dipole to the left, and the two bonds on the left have an equal resultant to the right. The dipoles cancel, so the molecule is nonpolar.
