The base composition of a double-stranded DNA molecule is 26% adenine. What percentage of this molecule is the base guanine? Give only the answer in numerical form so that Moodle will grade your answer correctly. Do not write "%".
Answer:
26
Explanation:
According to Chargaff's rule, a typical DNA molecule must have an equal ratio of both purine and pyrimidine bases. Purine is made up of Adenine and Guanine bases while pyrimidine is made up of Thymine and Cytosine bases.
Hence, if the amount of Adenine in DNA is 26%, the amount of Guanine would also be 26%. This would leave the remaining 48% of the DNA as Thymine and Cytosine to be shared in an equal proportion of 24% each.
In summary:
If Adenine = 26, Guanine would also be = 26
Adenine + Guanine = 52%
Thymine + Cytosine = 48%
which list correctly matches the functions to the types of carbohydrates
Answer:
This question is incomplete; it lacks options and they are:
A) Energy: glycogen and starch
Structure: cellulose and chitin
B) Energy: cellulose and chitin
Structure: glycogen and starch
C) Energy: chitin and glycogen
Structure: cellulose and starch
D) Energy: cellulose and starch
Structure: chitin and glycogen
The answer is option A
Explanation:
Carbohydrates are biological molecules in living systems. Polysaccharides are a type of carbohydrate molecules, which are polymers made up of monomers called monosaccharides. Monosaccharides such as glucose, fructose etc. are joined together by glycosidic bonds to form this polysaccharides. However, polysaccharides found in nature are classified based on their function in their found organisms.
1) Energy: Glycogen and starch are the two carbohydrate polymers that function in this aspect. They are both made up of long chains of glucose unit linked by α glycosidic bonds. Glycogen stores energy in the animal cells while starch stores energy in plant cells.
2) Structure: Cellulose and Chitin are the two carbohydrate polymers involved in this function. Cellulose is made up of glucose monomer linked together by β glycosidic bonds. It is the major structural component found in the cell wall of plant cells. Chitin is also a polymer of N-acetyl glucosamine and the major structural component of the cell wall of oorganisms like fungi.

Photosynthesis and cellular respiration are the
driving forces behind which of the following
cycles?
A. water cycle
B. nitrogen cycle
C. cell cycle
D. Carbon cycle
Answer:
it is under a force of carbin cycle
D.CARBON CYCLE
Photosynthesis and cellular respiration are the driving forces behind carbon cycle.
What is carbon cycle?Photosynthesis and cellular respiration are the primary processes responsible for driving the carbon cycle, which is the movement of carbon through the Earth's atmosphere, oceans, and land.
Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into glucose and oxygen using energy from sunlight. This process removes carbon dioxide from the atmosphere and stores it in the form of glucose, which is used by plants for growth and energy.
Cellular respiration is the process by which cells convert glucose and oxygen into energy, releasing carbon dioxide and water as waste products. This process occurs in all living organisms and is the reverse of photosynthesis.
The carbon cycle is also influenced by other processes such as the decomposition of organic matter, the burning of fossil fuels, and the release of carbon dioxide from volcanoes.

A 22-year-old woman engaging in a political protest goes on a hunger strike on a prominent corner in a city park. She refuses all offers of food except for water through the first 2 weeks. Under these conditions there is a decreased reliance on which of the following pathways for fuel?a. β-oxidationb. Lipolysisc. Ketogenesisd. Gluconeogenesis
Answer:
β-oxidation and gluconeogenesis
Explanation:
This 22-year-old woman, by not eating her food for a long time, entered a period of prolonged fasting.
Which there are no glycogen reserves, since they were depleted and neither were glucose assimilations by the cells because the person only ingested water.
Prolonged fasting is extremely dangerous because fatty tissues are degraded resulting in ketone bodies that are considered toxic and cross the blood-brain barrier.
Once the fat tissue reserve is completely finished, the body will enter into proteolysis of the body's own structural proteins in order to obtain energy, this is how the phenomenon of abrupt consumption of muscle tissue occurs.
Could somebody help me with this please?
Answer:
The ENDOPLASMIC RETICULUM serves important functions particularly in synthesis ,folding,modification and transport of proteins . The GOLGI BODY plays key role in sorting many cells proteins and membrane constituents and in directing them to their proper destination. The MITOCHONDRIA produce energy necessary for cells survival and functioning . The RIBOSOMES assumes the role of bringing together amino acids to form proteins.

what is difference between electron microscope and light microscope?
Answer:
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscope

¿En qué fechas se presentan las estaciones de verano e invierno en el hemisferio sur? Si al ver el mapa comprobaste que el Perú se encuentra en el hemisferio sur, entonces, ¿cuándo es verano y cuándo es invierno en el Perú? ¿En qué se diferencian el afelio y el perihelio? ¿Por qué la distancia de la Tierra al Sol en ciertas épocas del año no influye en las estaciones? ¿Tiene que ver que caiga lluvia en enero en algunas regiones del Perú para decir que están en invierno?, ¿por qué?
Answer:
En el hemisferio sur el verano comienza en diciembre y finaliza en marzo, mientras que el invierno comienza en junio y finaliza en septiembre.
Perú se encuentra en el hemisferio sur, con lo cual el verano comienza el 21 de diciembre y finaliza el 21 de marzo, mientras que el invierno comienza el 21 de junio y termina el 21 de septiembre.
El afelio indica a la mayor distancia posible en la órbita de un planeta con respecto al Sol, mientras que el perihelio refiere a la menor distancia posible (es decir, el punto de mayor cercanía posible) entre la órbita de un planeta y el Sol. En la Tierra, el afelio se produce a comienzos de julio, donde nuestro planeta dista aproximadamente 152 millones de kilómetros con respecto del Sol, mientras que perihelio se produce a principios de enero, donde la Tierra dista aproximadamente 147 millones de kilómetros con respecto del Sol.
La caída de lluvia es un fenómeno independiente a la estación del año, es decir, la lluvia caída en enero o julio no modifica que en el hemisferio sur nos encontremos en verano e invierno, respectivamente. En algunas regiones las lluvias se concentran en un determinado período del año, lo cual es un fenómeno meteorológico que tampoco tiene incidencia sobre la estación del año.

Answer - two haploid cells
Hope it helps.
When a cell undergoes meiosis, one diploid cell ends up dividing into two haploid cells. Therefore, option A is correct.
What is meiosis ?Meiosis is a special type of cell division in which reduction of cell occurs, Therefore, it is also called as reduction division because it reduces the number of chromosomes to half the normal number.
When fusion of sperm and egg occurs, baby will have the correct number. When a cell undergoes meiosis, one diploid cell ends up dividing into two haploid cells. These cells are our sex cells, sperm in males, eggs in females.
The germ cells undergo the process of meiosis to produce haploid cells that are the sperm and the egg. The development of a new organism is then initiated by the mixing of these gametes at fertilization.
Thus, option A is correct.
