Answer:

a. When the hydrogen ion concentration decreases, the hydroxyl ion concentration also decreases.

Explanation:

it is false because the concentration of hydroxyl ions remain constant. When H+ decreases, OH- concentration is automatically higher than H+. Both of them can't be decreased at the same time.

Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half from the female. (i.e. maternal and paternal alleles contribute equally).

I hope you get the answer!!!

A cell that contains organelles called chloroplasts

kupik [55]

Explanation:

A cell that contains organelles called Chloroplasts could be found in plants. 

Chloroplasts are organelles that conduct photosynthesis, where the chlorophyll(green pigments found in plant) captures the energy from sunlight, converts it, and stores it.A chloroplast is a type of organelle known as a plastid.

Answer:

Adaptations to a common environment and examples of convergent evolution

Explanation:

Convergent evolution is a process by which two independent and phylogenetically separated organisms, get to develop similar structures or behavior to survive. These structures make possible a better performance in a similar environment. These organisms are morphologically or ethologically similar in their whole bodies or just in parts.

Convergent evolution occurs in different phylogenetic branches independently from each other. It results from the need of different organisms to adapt to a similar environment and to solve a problem from that particular ecological niche. Ecological pressures acting on them might be similar, modeling the organisms´ phenotype. Each evolutive branch ends by developing the same structures, which they both find effective in their environment.

In the exposed example, Ichthyosaurs (reptile) and fishes are separated species on evolutive time, corresponding to different phylogenetic lineages. Both of them inhabit the same aquatic environment. Pressures of the habitat acted on them and modeling their phenotypes. These species need to adapt to living in water, moving, feeding, scaping, chasing, etc. So both species arrived at the same solution. They developed dorsal fins and tails, which are important to stabilize the body in the water while swimming, making it more hydrodynamic and getting to propel better.
