Answer:
1.) stromatolites
2.) photosynthesis
3.) Ordovician
4.) Cambrian
5.) oxygen
6.) As Earth cooled, carbon dioxide dissolved in the early ocean. Cyanobacteria consumed carbon dioxide and converted it to oxygen. Methane was removed from the atmosphere as oxygen was produced, eventually leading to the Cambrian Explosion.
7.) Metabolic processes that use oxygen produce more energy than anaerobic metabolism. Simple diffusion of oxygen would limit the size of a multicellular eukaryote, but animals evolved ways to transport oxygen to their tissues, which permitted an increase in size.

Explanation:
Pyramids depicting the number of organisms or biomass may be inverted, upright, or even diamond-shaped.
Energy pyramids, however, are always upright. Why?
Answer:
The correct answer is - as energy lost at every trophic level.
Explanation:
In any ecological ecosystem the energy pyramids always upright unlike other pyramids such as biomass showing the number of organisms, that can be diamond shape, inverted or upright.
The main reason behind this is due to the fact that it is only a pyramid in the ecosystem that always unidirectional in the food chain which is always some energy lost with an increase in the trophic level in the food chain. This loss of energy always gets back to the atmosphere in each step of the food chain.
As the energy is lost at every trophic level, the energy pyramids are always upright. A further explanation is below.
In whatsoever biological environment, the energy pyramid always seems to be straight, unlike some of the other pyramidal, including such biomass, which might be diamond-shaped, overturned, as well as upstanding.Essentially the food chain is simply a pyramid, and there is always some power loss as that of the primary consumers throughout the chain increases.
Thus the response above is right.

17. Explain how carbon reservoirs can
be accessed without the influence
of humans.
Answer:Without human interference, the carbon in fossil fuels would leak slowly into the atmosphere through volcanic activity over millions of years in the slow carbon cycle. ... About half of these emissions are removed by the fast carbon cycle each year, the rest remain in the atmosphere.
Explanation:Hope this helps you!
In the slow carbon cycle, volcanic activity would release fossil fuel carbon into the atmosphere over millions of years without human intervention. The rapid carbon cycle removes half of these emissions annually, leaving the rest in the atmosphere.
What are 4 carbon reservoirs?
These are the reservoirs or sinks that carbon moves through as it cycles through the environment. Carbon is returned to the atmosphere through a wide number of different processes, including the decomposition of organisms, the eruption of volcanoes and fires, the combustion of fossil fuels, and more.
Carbon reservoirs contain substantial quantities of carbon between processes.
Burning fossil fuels such as natural gas, coal, and oil releases CO2, which is damaging to the environment and to individuals.Therefore, the carbon stocks such as fossil fuels have been used by humanity.

Outline the effect of the following mutations:
TAG-> TAT
TAC-> TCC
Answer:
TAG-> TAT >> sense mutation
TAC-> TCC >> missense mutation
Explanation:
A sense mutation is a type of mutation that changes a stop codon into a sense codon, thus producing an elongated protein. The TAG codon (UAG in the RNA) is a stop codon, while TAT (UAU) encodes for tyrosine, thereby TAG-> TAT is a sense mutation. On the other hand, a missense mutation is a type of point mutation where a single nucleotide change generates a new codon which encodes a different amino acid. In this case, the TAC codon (UAC) encodes for tyrosine, while TCC (UCC) codon encodes for serine, and therefore TAC-> TCC is a missense mutation (Tyr to Ser mutation).

Which seatement correcsy describes celular respiration?
O
Carbon dioxide plus sugar makes oxygen energy and water
O Carbon dioxide plus water makes oxygen sugar and energy
O Ceygen plus sugar makes carbon diocide energy, and water
O Ceygen plus water makes carbon diocide, sugar and energy
Answer:
Explanation:Durante la respiración celular, una molécula de glucosa se degrada poco a poco en dióxido de carbono y agua. Al mismo tiempo, se produce directamente un poco de ATP en las reacciones que transforman a la glucosa. No obstante, más tarde se produce mucho más ATP en un proceso llamado fosforilación oxidativa.Las células procariotas llevan a cabo la respiración celular dentro del citoplasma o en las superficies internas de las células. Aquí se hará mayor hincapié en las células eucariotas, en donde las mitocondrias, son el lugar donde se produce la mayoría de las reacciones.
Se produce en la mitocondria. La respiración celular, como componente del metabolismo, es un proceso catabólico, en el cual la energía contenida en los sustratos usados como combustible es liberada de manera controlada.

Which of the following represents an agricultural factor greatly decreasing the availability of crops?
Answer:
Climate.
Explanation:
Climate is the factor which is responsible for the decreasing the availability of crops because climate is the factor that allows crops to grow in the region. Suitable climatic conditions allows us to grow more plants in the region while on the other hand, less or no crops can be cultivated in the harsh climatic conditions. The plants in the harsh climatic condition are unable to grow such as desert where the temperature is very high and no rainfall occurs to support growing of crops.

Which statement below would best illustrate the concept of natural selection?
A an organism can return to the characteristics of its ancestors
B a population of animals will move from one region to another
those organisms that are best adapted to the environment will survive to produce more offspring
D all organisms are made up of cells
Answer:
C. those organisms that are best adapted to the environment will survive to produce more offspring
Explanation:
Natural selection is a key concept in the formulation of the theory proposed by Darwin in 1859. Natural selection is defined as the main force that drives the prevalence and the increase of advantageous phenotypic traits. Selection natural acts by differential survival and reproduction of individual organisms that have better adapted to the environmental conditions in which these organisms live. These organisms with a greater adaptive fitness have more chances to survive and reproduce, thereby transmitting (and perpetuating) their genes to the following generations.

those organisms that are best adapted to the environment will survive to produce more offspring

The genetic researchers at Bay Medical Company are interested in spiders with the trait for medium silk flexibility. They
think this sik can be used for medical purposes such as for making stitches and for creating artificial tendons. Why do
you think offspring B has the medium silk flexibility trait?
Answer:
Due to similar shape.
Explanation:
I think offspring B has the medium silk flexibility trait because this offspring B is identical to the spider that is responsible for medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele whereas very littles number of offspring is similar in appearance with the female spider due to recessive allele. If the male spider has medium silk flexibility trait so more number of offspring has medium silk flexibility trait as compared to others.
The people at the Medical research bay company are researching on spiders. the trait for the medium silk flexibility. The silk can be used for medical purposes and creating other tendons.
