Answer:
The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.
The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.
What is cell membrane?
The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
Moreover, the cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Hence, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

Answer:
C. Mitochondria
Explanation:
if humans began hunting and driving the great barracuda to extinction how would this affect the ecosystem (answer should discuss biodiversity, food webs, and food chains)
Answer:
Generally considered to be the tertiary consumers (top level of the food pyrmaid), barracuda feed on an array of preys including grunts, groupers, snappers, small tunas, mullets, killifishes, herrings, and anchovies. By feeding on these marine organisms, barracuda prevent them from increasing in number.
Now let's barracuda's number starts decreasing due to hunting and other reasons. This will result in other primary and secondary consumers to increase in population. An increase in the number of primary and secondary consumers in the food chain will result in a decreasing number of plants, i.e. the number of producers decreases. Hence, this will negatively affect other connected food chains in the marine food web.

What is photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
It is carried out by algae, plants and even some microorganisms.

Explica qué son los codones y los anticodones La siguiente secuencia de nucleótidos de ADN codifica para una secuencia de aminoácidos que forman una proteína hipotética, encuentre la secuencia de codones, anticodones y aminoácidos que se forman 5 ` A T G A G C A C C C A A A C T T G C TC T T A T T C T A A A A A G A C T 3
Answer and Explanation:
La informacion genetica de ensamblaje de aminoácidos durante la sitntesis proteica, se almacena en unidades llamadas codones.
Un codón es una secuencia corta de tres nucleotidos provenientes de la cadena de ADN o ARN mensajero. Cada codón representa uno de los 20 aminoácidos disponibles para sintetizar la proteina. En total hay 64 codones, de los cuales 61 codifican aminoácidos (mas de un codón puede codificar para el mismo aminoácido), de los cuales uno de ellos a parte es el codon de inicio de sintesis proteica. Los restantes tres codones corresponden a codones de finalización.
El anticodón es la secuencia de nucleótidos presentes en ARN de transferencia, que complementa a cada codón de ARN mensajero. De esta forma el ARNt reconoce el aminoácido correspondiente y lo ensambla en la nueva proteina.
ADN ⇒ 5 ` ATGAGCACCCAAACTTGCTCTTATTCTAAAAAGACT 3

La proteina se construye en función de la información del ARNm, es decir que para la selección de aminoácidos, se consideran los codones del ARNm, y no los anticodones de ARNt.

A 43-year-old Caucasian man with a 20-year history of bipolar disorder presents for the first time with long-term polyuria and polydipsia. He previously took lithium for mood stabilization for 15 years before initiating divalproex sodium therapy. He stopped using lithium because of the polyuria, but he felt that the polyuria never fully subsided. His weight is stable, and he has no other urinary complaints. His blood pressure is 115/80 mmHg and his physical exam is normal. His urinalysis shows no blood, cells, protein, glucose, nitrate, casts, or crystals.
What is the most likely cause of his polyuria?
1 Central diabetes insipidus
2 Nephrogenic diabetes insipidus
3 Polyuria secondary to hyperglycemia
4 Polyuria following acute kidney injury
5 Polyuria secondary to polydipsia
Answer:
The correct option is 2 Nephrogenic diabetes insipidus.
Explanation:
Nephrogenic diabetes insipidus (NDI) occurs when the renal tubule response to vasopressin (ADH) is weakened, resulting in the excretion of large volumes of dilute urine.
As the renal tubules do not respond to vasopressin (antidiuretic hormone) and are unable to reabsorb filtered water back into the body, the kidneys create a high volume of dilute urine in nephrogenic diabetes insipidus.
Nephrogenic diabetes insipidus (NDI) can be inherited or develop as a result of disorders that impede the ability of the kidneys to concentrate.
Therefore, the correct option is 2 Nephrogenic diabetes insipidus.
That is, the most likely cause of his polyuria is nephrogenic diabetes insipidus.

Which of the following suggests what happens when a mutation occurs in an organism? Select one:
Genes begin to appear in different individuals of the population all at once.
The organism develops new traits as a result of using a particular body part.
New traits appear from changes in the instructions given to the cell by the DNA. Useless traits are removed from the organism due to the loss of nucleotides
Answer:
New traits appear from changes to the DNA..
Explanation:
A mutation is when DNA is changed or altered in some way, causing it to tell the cells to do something different from what they usually do such as growing a body part a certain way, or making skin regenerate a certain way. some mutations are specific to one individual person or thing, other mutations are passed down through generations and become a new normal for the species. new diseases such as viruses are often caused by the virus mutating...this is how we have so many different strains of the flu...
