Answer:
When starfish were removed from their environment, the species richness of that area went down. This was because the starfish ate the mussels, and when the starfish were removed, the mussels became abundant and preyed on many of the other species.
This experiment showed that the starfish were a keystone species. A keystone species is a species that has a low biomass but a large impact on the community they are living in.
The answer is A smaller fragments will move faster.
Answer:
In this case, it is likely that the polypeptide chain assumed an alpha helix configuration because the lipid bilayer did not have beta-barrel proteins.
Explanation:
A polypeptide chain is naturally polar, however, a lipid bilayer is naturally non-polar. This makes it difficult and even prevents the polypeptide chain from crossing a lipid bilayer, since the composition of these two elements does not allow them to mix. In that case, the polypeptide chain has two options to take to successfully cross the lipid bilayer.
The first option that the polypeptide chain has is to allow the creation of twisted beta sheets in the shape of a closed barrel in its structure. This only works if the lipid bilayer has beta barrel proteins in its composition to act as a transport channel for the polypeptide chain. However, few lipid layers have this protein.
Most likely, the polypeptide chain assumes an alpha helix conformation to cross lipid bilayers that do not have beta-barrel proteins. By assuming the beta conformation, the polypeptide chain reinforces the hydrogen bonds present in its composition, allowing it to cross the lipid bilayer without having its conformation and structure disassembled.
Changes to the drug may be helpful if it turns out that one is the source of the problem. Mechanical aids: Penile implants and vacuum devices may be able to assist males with erectile dysfunction (the inability to achieve or maintain an erection).
Any stage of the sexual response cycle is susceptible to sexual dysfunction. You are unable to enjoy sexual activities to your delight.
The classic stages of the sexual response cycle include anticipation, plateau, climax, and resolution. Both arousal and desire are a part of the sexual response's excitement phase. It's vital to understand that women don't always experience these phases sequentially.
The Sexuality Information and Education Council of the United States (SIECUS) states that a sexually healthy teen demonstrates or has the following characteristics in their interactions with classmates, parents and other members of their family, as well as other close friends and intimate partners.

Answer:
Photosynthesis
Explanation:
In photosynthesis, carbon reduction helps make glucose, the oxygen is formed with the reduction of water in the photosystems 2 and 1.
In cellular respiration, both of these compounds would be reactants.
