<span>Presence of oxygen means that the organisms are not anaerobic so the answer is D. algae. Eukaryotic and prokaryotic cells can be anaerobic meaning that they live in circumstances where there's no oxygen. Algae were the first that required oxygen to thrive. Cyanobacteria are like other bacteria parts of the prokaryotic cell type.</span>
B. Populations are a group of the same species in a place at the same time.
Answer:
Due to presence of ocean near it.
Explanation:
The heat capacity of water is higher than soil means that soil quickly heats up at day time and cool down at night whereas, water takes more time to heat up and cool down so that's why those areas present far from ocean observe high fluctuation in day and night temperatures due to quickly heat up and cool down as compared to those areas present near water such as coastal areas which takes more time to heat up and cool down..
Answer:
Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and fro movement of water molecules along the concentration gradient.
Answer:
The shape of the active site may not be complimentary to the substrate anymore, so the substrate may bot be able bind to the active site
