Where does the heat from current climate change ultimately come from?(1 point)
earnstyle [38]

Climate change causes changes in weather conditions over a long period of time.

<h3>What is climate change?</h3>

Climate change refers to those long time changes in the weather condition of a place.

The heat from current climate change ultimately comes from energy from the sun, trapped by carbon dioxide in the atmosphere.

As the earth's temperature increases, the processes on earth are affected such as increased precipitation and increased sea levels.

An example of a positive  feedback loop is;

  • Temperatures rising cause ice and snow to melt, which causes more heat to be absorbed by the ground, causing temperatures to rise more.
  • Melting ice causes more sunlight to be reflected into the atmosphere, causing the temperatures on Earth to increase, which then causes more ice to melt.

The most effective way for an individual to reduce climate change on individual basis is to turn off the lights after leaving rooms.

What phenotypic ratio would you expect as a result of a test cross between a dihybrid organism and one that is homozygous recess
Artyom0805 [142]

Answer:

¼ or 25% will be dihybrid organisms, ¼ will be heterozygous at first locus and recessive homozygous at other locus , ¼ of them will be recessive homozygous at first locus and heterozygous at other locus, and ¼ of them will be homozygous recessive for alleles at two independent loci.

Explanation:

A dihybrid organism is one that is heterozygous at two different genetic loci. So if we name one gene with D and other gene with R, dihybrid organism will have genotype DdRr.

If we cross that organism with the one that is homozygous recessive for alleles at two independent loci ddrr:

P: DdRr  x ddrr

4. Which event would be the most predictable one year in advance of the event?
Black_prince [1.1K]

Answer:

1. an eclipse of the Sun

2. state (phase) of matter

3. 5.0 g/cm3

Explanation:

1. Eclipse of the sun occurs when the planetary bodies align in such a way that causes the moon to block sunlight from reaching the Earth. The eclipse of the Sun will be the most predictable occurrence because it follows a pattern of occurrence. Eclipse of the sun occurs after a specific period of time, hence, based on this, scientists can predict that when it will occur next using its previous pattern of occurrence.

2. Considering the following groups: Group A: water, aluminum, water vapor

Group B: gasoline, ice, air

Group C: alcohol, iron, oxygen

One would realize that each constituent of each group exists in a particular state of matter. For example, in group B, gasoline is a liquid, ice is a solid while air is a gaseous mixture. Same applies for group A and C where water and alcohol are liquids, iron and aluminum are solids, while water vapor and oxygen are gases.

This shows that the STATE (PHASE) OF MATTER was the basis of classification.
