How has earths atmosphere changed over time
Answer:
Hey mate....
Explanation:
This is ur answer.....
When earth was first formed, its atmosphere was likely composed of hydrogen, helium, and other gases that contained hydrogen. Over a vast amount of time, millions of years, the earth gradually cooled. When the temperature dropped enough, water vapor condensed and went from a gas to liquid form. This created clouds.

Before life began on the planet, Earth's atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth's surface and in the oceans, much of the carbon dioxide was replaced with oxygen.

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways. One result of the rapid increase of motor vehicles was air pollution, especially in cities, that had serious impacts on public health and the environment.

A. Diffusion
B. Passive transport
C. Exocytosis

At the end of binary fission, the two daughter cells that result are genetically _________ to each other and to the parent cell.
A. different
В. identical
C. similar
D. opposite
Answer:
B. identical
Explanation:
In binary fission, the parent cell divides into two. The genetic material (DNA) of the parent cell is duplicated in the daughter cells. Having the same genetic composition makes the cells genetically identical.
What is the main difference between migration, immigration, and emigration?
Answer Migration, in turn, covers both immigration and emigration. Another key difference is, immigration is permanent while migration doesn’t have to be. People who travel and stay in a country for a few months — for instance, because of a seasonal job they have — are also called migrants.
Explanation:
somatic cells can also be called
Answer:
They are also called vegatal cells.
Explanation:
Soma- in Latin, means (Body),
So, Somatic cell .. means a Body cell,
Generally, our body contains 2 types of cells according to number of chromosomes :
1- Somatic cells : - almost all body cells are somatic cells
- contain 46 chromosomes (diploid)
2- Germ cells : - only sperms in male & Eggs in female, are germ cells
- they contain 23 chromosomes (haploid)
- they are supposed to unite together (Egg & sperm) to form a diploid cell (23+23=46) ...that will eventually grow into a baby.
tRNA:
a) helps to translate codons to DNA
b) transfers anticodons to rRNA
c) recognizes anticodons in the mRNA
d) joins one specific amino acid
Answer:
A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA (tRNA) does this by carrying an amino acid to the protein

What is evolution?In biology, evolution is the alternative withinside the traits of a species over numerous generations and is based at the method of herbal selection. All cutting-edge people are 99.9% much like each other with inside the part of the human genome that codes for proteins.
In equal regions of the genome, we're 98.8% genetically much like chimpanzees, 75% genetically much like chickens, or even 60% genetically much like banana tree evidence from fossils, proteins, and genetic research shows that people and chimpanzees had a not unusual place ancestor tens of thousands and thousands of years ago. Most scientists trust that the 'human' own circle of relatives tree (called the sub-organization hominin) breaks up from the chimpanzees and different apes approximately 5 to seven million years ago.Read more about the hormone

Which regions have been most affected by rising temperatures?
Answer:
Japan
The Philippines
Germany
Madagascar
India
Sri Lanka
Kenya

Explanation:
animals of the same general body types have the same anatomy true or false
Animals of the same general body types having the same anatomy is True.
Anatomy is the study of the body parts, structures and functions of
organisms.
In situations where animals have the same general body type , then it means
they also have the same anatomy. A good example is mammals which have
the same structure of body parts and the same anatomy.
Organisms with different body structures however have an entirely different
anatomy which is why True is the most appropriate choice.

Use examples to explain how the biosphere interacts with two other of Earth's spheres. Explain the interaction for each using complete sentences.
Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.
