A marsh supports a large population of cattails, which are tall wetland plants. Purple loosestrife, an invasive wetland plant, is introduced to the marsh. Both purple loosestrife and cattails require access to sunlight and space along the floor of the marsh to grow. What effect will the growth of purple loosestrife have on the marsh's carrying capacity for cattails?

the answer to your question is sperm

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

the three components of a nucleotide are the nitrogenous base, the phosphate group and the five-carbon sugar.
