I believe it is A or B. I’m quite torn. I did research to back my answer up and it’s said that the atmosphere would become less and less oxygenated, perhaps becoming unbreathable for humans. The temperatures would also become lower, The land would fry.
Answer:
The incidence of mid-digital hair will not change because it offers no selective advantage or disadvantage.
Explanation:
The traits of an organism are determined by the genes of an organism.
In the given question, the trait is the hair growth on the middle digit or finger which is passed on to the generation but in some, it is expressed and in some, it is not.
This trait does not provide any benefit to the humans neither they are disadvantageous and thus is the neutral trait. Therefore, this trait will not change over time.
Thus, the selected option is correct.
Answer:
a. As CO2 increases, the temperature also increases.
Explanation:
Carbon dioxide (CO2) is an atmospheric molecule produced naturally via respiration or artificially via burning of fossil fuels. CO2, as rightly stated in this question, has been referred to as a greenhouse gas because it acts to trap the sun’s heat on Earth.
Logically, an increase in the amount of greenhouse gas like CO2 released into the atmosphere means an increase in the greenhouse effect or global warming (increase in global air temperature). However, according to the GRAPHICAL REPRESENTATION in this question, an increase in the ppm concentration of CO2 led to an increase in the temperature (°F) of the globe over the years.
As depicted on the graph, at a CO2 concentration of 390ppm, the relative temperature was at over 1°F.
Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small.
explicación:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
