Answer:
Explanation:
A fall in temperature can also adversely affect cell and cell membranes. At low temperatures, the phospholipids' fatty acid tails are moving less and stiffer. This reduces the membrane's overall fluidity as well as reduces its permeability and perhaps limits the entry into the cells of vital chemicals like oxygen and glucose. Also, low temperatures can impede cell development by preventing cell size expansion.
In severe cases, such long term exposure to sub-freezing temperatures, fluid in the cell can start solidifying and can form crystals that breach the membrane and destroy the cell.
Well if both are dominate colors the phenotype of the offsprings would be pink or spotted. if the red flowering plant was dominate and the white flowering plant is recessive then the phenotype would be 100% red, they would just be the carrier of the white color. if the white flower is dominate and the red is recessive the flowers phenotype would be 100% white, but be carriers of the red color.
The right answer is c. 3 to 10 million
The latest estimates are a bit more precise: there are 8.7 million living species (which is included in the range between 3 and 10 million), 6.5 million on land and 2.2 million in the water. Which is amazing, since there is more sea than land on our planet.
Researchers estimate that there are 7.77 million animal species, only 298,000 plant species and 611,000 species of fungi and molds.
If a person is "sterile", this means that they cannot reproduce. The word "sterilized" is essentially stating that there is no productive activity in order to be able to reproduce.
Answer:
Punctuated Equilibrium
Explanation:
The phyletic gradualism model and the punctuated equilibrium are aspects models of macroevolution that are characterised with varying patterns.
However, the punctuated equilibrium model of evolutionary history consists of geologically long periods of inactivity (stasis) with little or no evolution, interrupted or "punctuated" by geologically short periods of rapid evolution.
