Explanation: The energy pyramid describes how energy gets distributed through an ecosystem. The more there is of an organism on the energy pyramid, the more it gives overall to the ecosystem. The less there is of an organism, the less it gives to the ecosystem. Take the Floridian Everglades as an example. There is an abundance of sawgrass, and that makes up the foundation of the system, along with mangroves and such. But there are less of predators in the ecosystem because they only feed of of their prey like small mammals or fish. They never start the food chain, they end it.

Answer:
1. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons.
Treatments: Blood transfusion
Symptoms: Pain
2. Diabetes is the <u>condition in which the body does not properly process food for use as energy</u>. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies.
3. Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acne is most common among teenagers, though it affects people of all ages.
Answer:
C) Both Suresh and Gail could be correct.
Explanation:
The pre-messenger RNA (pre-mRNA) transcript obtained after transcription of eukaryotic genes must undergo several processing events, including a process known as intron splicing, where introns (i.e., the non-coding sections of an RNA transcript) are removed and exons (coding regions) are joined to form a mature mRNA molecule. The three prime untranslated (3′-UTR) region of this mRNA can also bind to regulatory non-coding RNAs such as, for example, miRNAs which inhibit gene expression by inhibiting translation and/or by triggering its degradation. Moreover, the 3′-UTR region may also contain silencer sequences that bind to repressors in order to inhibit gene expression. On the other hand, translation refers to the process by which an ordered polypeptide chain (i.e., a protein) is synthesized by using the information contained in an mRNA molecule. In consequence, in the case under consideration, the mutation in the second gene could affect both RNA processing and the regulation of translation, thereby equally affecting HOX3A protein synthesis.
