Answer:
The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without this atmosphere. Radiatively active gases in a planet's atmosphere radiate energy in all directions.
Yes earth needs a greenhouse effect to support life .
When the solar radiation falls on the earth's surface, put of the radiation is absorbed and a part is reflected back inte space. Greenhouse gases like carbon diraide and methane present in the atmosphere absorb some of the radiated heat. These trapped radiation further warm the earth The trapping of the sun addition by the gases present in the urthi atmosphere is called greenhouse effect. Without the natural greenhouse effect, life would not have been possible on the carth because in the absence of such an ctfect the cu surface would have been too cold to sustain life.
Many aspects of global climate are changing .High temperature extremes and heavy precipitation events are increasing, glaciers and snow cover are shrinking, and sea ice is retreating. ... Greenhouse gas emissions from human activities will continue to affect Earth's climate for decades
currently due to the use of many vehicles , fossils etc a lot of pollution is caused and concentration of CO2 (carbon dioxide ) has increased which is causing the earth to become to hot which is leading to melting of glaciers which causes global warming .
hope you've understood ☺️
Answer:
The correct answer is - A. RY, rY, Ry, ry
Explanation:
Gametes are the sex cells or reproductive cells that are haploid in number. Gametes carry only one allele of each gene or chromosome in any organism. The male gamete called an egg or ovum whereas the male gamete called sperm or pollen.
In this case, the heterozygous plant has the genotype RrYy. In each of the gametes, there would one allele of each gene. The gametes get a dominant R and a dominant Y allele and a recessive r and a recessive y allele. Each produces 25% each of RY, Ry, rY, and ry.
The chemical energy released in a chemical reaction is a product of the reactants in a reaction. In a reaction, something is either broken down or combined to form something new.
<u>Answer</u>: A) Africa and South America only
As shown in the map, the fossil evidence suggests that Cynognathus lived on the modern day continents of South America and Africa. Thus, from this distribution and the fragmentation of the ancient landmass into today's continents, result in the distribution of Cynognathus offspring species also only within the continents of Africa and South America.
The next bone healing stage is called the hard callus<span> stage.This transformation occurs when bone forming cells called osteoblasts travel across the </span><span>soft callus.</span>
