Mitochondria and chloroplasts are the two organelles that have their DNA separated from the DNA contained in the nucleus.
Organelles are the specialized organs for a eukaryotic cell to perform various functions. They are usually protected by a membrane(s) and are found in the cytoplasm of the cell. The various organelles found in a eukaryotic cell are the nucleus, peroxisomes, lysosomes, mitochondria, chloroplasts, ribosomes, Golgi apparatus, and endoplasmic reticulum.
The nucleus is the site for DNA replication. It then produces RNA by the process of transcription. This RNA is then transferred to ribosomes for protein synthesis. These synthesized proteins are then transferred to various cell organelles to perform their specific functions.
Meanwhile, the mitochondria and chloroplasts are the two organelles that do not need proteins synthesized by the ribosomes. They can synthesize their proteins themselves as they have their DNA separated from the DNA of the nucleus. Because of this characteristic, they are also referred to as semi-autonomous.

in fermentation, the only atp produced was during glycolysis and the fermentation reactions usually result in resetting the nadh to nad.
It is true that in fermentation, the only ATP produced was during glycolysis and the fermentation reactions usually result in resetting the NADH to NAD.
Fermentation is the process of breakdown of sugars to yield lactic acid or alcohol, along with some energy. This process occurs in the absence of oxygen and the by-products of the reactions are heat and an effervescence of CO₂. Fermentation commonly occurs with the help of yeasts.
Glycolysis is the process of breakdown to sugar to yield pyruvate. it occurs without the help of oxygen and is common process in both aerobes as well as anaerobes. The net gain of energy from glycolysis is of 2 ATPs and 2 NADH molecules.

Define osmosis and explain why it biologically important.
Explanation:
osmosis
refers to the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules through a cells partially permeable membrane
Importance
- it stabilizes the internal environment of the organism by balancing the level of water and intracellular fluids
General category: Biology.
Sub-category: Cellular membranes
Topic: Diffusion
Introduction:
Diffusion is the random movement of molecules in a given medium toward a state of equilibrium. Then, diffusion is the net movement from regions of greater concentration to regions of lesser concentration.
Explanation:First of all, remember that if a cell membrane divides a solution into separate compartments, the movement of the different solutes can be affected by the properties of the membrane. The passage of substances depends on whether the membrane is permeable or semi-permeable to different solutes.
Now, the concept of osmosis is based on the idea of diffusion. Osmosis is the diffusion of water across membranes. This means that water will diffuse from a region of its higher concentration (lower concentration of solutes) to a region of its lower concentration (higher concentration of solutes).
Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function. Remember that osmotic equilibrium is the ratio of intracellular fluid to the extracellular fluid. For example, osmotic balance is of vital importance in the functioning of the nephron.
We can conclude that the correct answer is:
Answer:Osmosis:
Osmosis is the diffusion of water across membranes where the water will diffuse from a region of its higher concentration to a region of its lower concentration.
Biological importance of osmosis:
Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function.

The primary sequence of a protein contains proline. What can you predict about its folded structure at that region?.
Answer:
The folded structure at that region of the primary sequence of a protein that contains proline will have an alpha helix at that .
Explanation:
Amino acids that feature a side chain with a cyclic ring system are known as aromatic amino acids.
Histidine, as well as proline,as well as proline, are two well known examples of aromatic amino acids.
These side chains of such amino acids used to make a protein determine the shape of the protein.
Alpha helices were created at that site when proline was present in the amino acid's main sequence.
As a result, an alpha helix would indeed be present within the folded structure of such a proline-containing protein's main sequence.
Amino acids' primary purpose is to act as that of the components that make up proteins. About Fifty to 2,000 amino acids are normally linked end to end in several configurations to form proteins. Each protein contains a different set of amino acid sequences that are folded and bent in a certain way.

Which manifestation would a nurse expect when assessing a child with insufficient growth hormone (gh) secretion?
On the growth chart, place lower than 10%
What causes the growth hormone to be released?Episodic hypothalamic hormones induce pituitary GH synthesis and secretion. Somatostatin (SST) suppresses GH synthesis whereas growth hormone releasing hormone (GHRH) promotes. The creation of IGF-I is induced by GH, and this in turn prevents the release of GH from the pituitary and hypothalamus.
The hypothalamus and GH action mediators govern growth hormone (GH) release from the anterior pituitary.
When you sleep, the majority of HGH is released in pulses. These pulses are dependent on the circadian rhythm, or internal clock, of your body.
The pituitary gland produces growth hormone. Its many duties include preserving healthy body composition and metabolism. Your bones enlarge if you have too much growth hormone. It is known as gigantism in children and causes a rise in height.
