<span>An organelle is a functional subunit enclosed by a membrane within a eukaryotic cell. The name "organelle" means little organ and the name comes from the analogy with organs: what an organ is to a body, an organelle is to a cell. So, the organelle is the organ of the cell. There are different types of organelles in cells, such as nucleus, mitochondria, Golgi apparatus, endoplasmic reticulum, chloroplasts, vacuoles, and they all have a different function. For example, the nucleus is the organelle which main function is control of cell activities. Mitochondria are organelles which main function is energy production. </span>
The answer for this question would be the second option. Genomic studies cover the analysis of the changes of genome by scanning the markers across complete sets of DNA. Based on these studies, the change in gene sequences happen that resulted to a change in the way that the brain interprets speech in between 4 and 9 million years ago.
It makes it stronger.

Answer;
Amino acid side chains have many carboxyl and amino groups.
Explanation;
-A buffer solution is a solution that resists changes in pH when small quantities of an acid or an alkali are added to it. It is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases.
-Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis.Small molecules such as bicarbonate and phosphate provide buffering capacity as do other substances, such as hemoglobin and other proteins.
-
Protein buffer systems depend upon proteins, as opposed to nonprotein molecules, to act as buffers and consume small amounts of acid or base. Since amino acids have the capability of reacting with both acid and base, they naturally act as buffers.
Answer:
Photosynthesis
Explanation:
The leaf (from Latin fŏlĭum, fŏlĭi) is the vegetative and generally flattened organ of vascular plants, specialized mainly to perform photosynthesis. The morphology and anatomy of stems and leaves are closely related and, together, both organs constitute the stem of the plant.
Typical leaves - also called nomophiles - are not the only ones that develop during the life cycle of a plant. From the germination, different types of leaves follow each other - coiled, primordial leaves, prophilic, bracts and antophiles in flowers - with very different forms and functions.
A nomophile usually consists of a flattened sheet, a short stem - the petiole - that joins the sheet to the stem and, at its base, a pair of appendages - the stipules. The presence or absence of these elements and the extreme diversity of forms of each of them has generated a rich vocabulary to categorize the multiplicity of types of leaves presented by vascular plants, whose description is called foliar morphology.
