Answer:
because they reduce interspecific competition
Explanation:
Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.
Chemical bonds formed when atoms gain/lose electrons, and oppositely charged ions attract. Ion. A particle having an electrical charge. Electronegativity difference between 0 and 0.3. Characterizes onpolar covalent bond.
Answer:
a) the selection intensity is 21bushels/acre
b) the response to selection is 12bushels/acre
c) The heritability is 0.57 (two decimal places)
Explanation:
Given:
mean grain yield population=72bushels/acre
mean grain yield selected individuals=93bushels/acre
mean grain yield new population=84busgels/acre
a) The selection intensity is given by:
SI=mean grain yield selected individuals-mean grain yield population=93-72=21bushels/acre
b) The response to selection is:
RS=mean grain yield new population-mean grain yield population=84-72=12bushles/acre
c) The heritability of grain yield is:
H=RS/SI=12/21=0.57
Answer: The correct answer is
No, because NaCl is Ionic
Explanation:
NaCl can pass through the cell membrane because it is Ionic and separates into Ionic components Na+ Cl+.
Cell membrane are phospholipids bilayers and have hydrophobic tails and face inside of the cells . The fatty acids tails are non polar and only non polar substances can pass through it but salts is a polar molecules because it is an ion and cannot pass.
