<h2>Answer:</h2>
The water will move in and out freely. The material transport which is due to the water transport will be affected.
<h3>
Explanation:</h3>
- Water is a partially polar molecules. Many ionic compounds and ions travel inside and outside the cell due to attachment with water molecule.
- As well as water movement is controlled due to its polar nature through cell membrane. and the cytoplasm and outer environment is separate due to non polar cell membrane.
- If the water become non polar then the movement through cell membrane will be easy for water. And the molecules dissolved in water will also be transported uncontrollably.
During anaerobic respiration , cells make energy without <u>Oxygen</u>
the energy obtained during anaerobic respiration is 2 ATP
Answer:
The answer is letter B
Explanation:
One species will take over most or all of the zone of overlap. Because there will be a competition between the two species. One wil thrive, while the other will eventually die out due to natural selection.
It is important to remind that according to the competitive exclusion principle, no two species can occupy the same niche.
Answer:
Species separated by a physical barrier for a long time, suffer allopatric speciation, so they can not interbreed anymore.
Explanation:
Allopatric speciation consists of the geographic separation of a continuous genetic background giving place to two or more new geographically isolated populations. These separations might be due to migration, extinction of geographically intermediate populations, or geological events. In this speciation, some barriers impede genetic interchange, or genetic flow, as the two new populations that are separated can not get together and mate anymore. These barriers might be geographical or ecological.
Vicariance is the geographical separation of an original population into two or more new groups. Discontinuities in the physical environment like rivers, mountains, water, etc., are physical barriers that impede genetic flow between the separated groups.
The process of allopatric speciation involves different steps:
- The emergence of the barrier.
- Interruption in the genetic interchange
- The occurrence of new mutations and their accumulation in time in each population. Slow and gradual differentiation.
- Genetic divergence by natural selection and reproductive isolation makes it impossible for the two groups to mate even if the barrier disappears.
- Prezigotic isolation mechanisms favored by selection once occurs a secondary contact between the new species in formation.
Meiosis makes haploid gametes like eggs and sperm cells
