Answer:
Fatty acid degradation produces acetyl-CoA
When carbohydrate concentrations drop, any available oxaloacetate is diverted to gluconeogenesis to produce the glucose necessary for red blood cell and brain function. If acetyl-CoA cannot enter the citric acid cycle (and acetyl-CoA cannot be converted to pyruvate in mammals), it is converted to ketone bodies.

una persona camina durante una hora y media y corre 4 km con velocidad constante ¿cuál era su velocidad en km/h y en m/s?
La respuesta es: su velocidad es 2.66 km/h, equivalente a 0.738 m/s.
Explanation
Para conocer la velocidad de una persona que recorrió 4 km luego de caminar durante una hora y media es necesario dividir la distancia (en kilómetros) total en el tiempo (en horas). Entonces la operación sería:
4km/1,5h = 2.66 km/h.
Posteriormente, para convertir 2.66 km/h en m/s es necesario aplicar la siguiente formula
2.66 km/h *(1000 m/1 km)*(1 h/3.600 s) = 0.738 m/s.

Which of the following shows the correct order in which sound information travels through the ear?
O Ossicles, eardrum, cochlea, cochlear nerve
Eardrum, ossicles, cochlear nerve, cochlea
O Eardrum, ossicles, cochlea, cochlear nerve
O Ossicles, eardrum, cochlear nerve, cochlea
The following shows the correct order in which sound information travels through the ear is Eardrum, ossicles, cochlear nerve, cochlea.
What is the cochlear nerve?The cochlear nerve, additionally called the acoustic nerve, is the sensory nerve that transfers auditory records from the cochlea (auditory vicinity of the internal ear) to the brain. It is one of the many portions that make up the auditory system, which permits powerful listening to.
We pay attention while sound waves journey thru the air to our eardrum, throughout our center ear, into our internal ear, and sooner or later to the auditory facilities of our brain. Our ears are constantly on and are constantly sporting sounds alongside this listening-to pathway.

In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria. The appropriate control for this experiment is to treat the transforming extract from heat-killed virulent bacteria with:
Answer:
Nothing
Explanation:
A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.
There is a U-tube in which solutions in two arms A and B are separated by a membrane. Arm A contains glucose with concentration of 0.4 mol per liter and sodium chloride with concentration of 0.5 mol per liter. Arm B contains glucose with concentration of 0.8 mol per liter and sodium chloride with concentration of 0.4 mol per liter.
The solutions in the arms of a U-tube (the figure) are separated at the bottom of the tube by a selectively permeable membrane. The membrane is permeable to sodium chloride but not to glucose. Side A is filled with a solution of 0.4 M glucose and 0.5 M sodium chloride (NaCl), and side B is filled with a solution containing 0.8 M glucose and 0.4 M sodium chloride. Initially, the volume in both arms is the same.
If you examine side A in the figure after three days, the concentrations of glucose and NaCl should be _____________.
Answer:
0.4 M glucose, 0.45 M NaCl

Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly sessile, feeding on their host plant's phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis?
Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.
Explanation:
A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.
The hypothesis can be tested by comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Plasmodial slime molds are characterized by:
Select one:
a. The ability to go from a single cell to multicellular organism
b. Their color and shape
c. The existence of multiple nuclei in a supercell
d. The presence of chloroplasts
Answer:
a,the ability to go from a single cell to multicellular organism
The existence of multiple nuclei in a supercell is the characteristic feature of the Plasmodial slime molds, hence option C is correct.
What are Plasmodial slime molds?It is one large cell called a supercell surrounded by a single membrane without cell walls having multiple nuclei, commonly founds on decomposing forest litter and rotting wood.
This organism is found by the fusion of multiple flagellated cells and which makes the structure of supercells, its formation depends on the availability of food.
It glides along the way where the presence of food particles is observed generally bacteria, lifting and engulfing this food. It has a diameter of 3 to 4 centimeters.
Therefore, Plasmodial slime molds are characterized by the existence of multiple nuclei in a supercell.

Answer:
a way to inform conservation efforts based on genetic information from species
Explanation:
Genetic studies in wildlife and captivity species provide significant information to understand aspects regarding the biology and ecology of species, especially endangered species. Many discoveries have been useful to solve several taxonomic issues, determine the risk of diseases, and explain reproductive problems, among other problems. What is even more important is that genetic knowledge helps to plan management programs and conservation. Together with other areas related to behavior and conservation, genetic knowledge provides the basis to carry out successful conservation strategies.

During Meselson and Stahl’s experiment, E. coli was grown on heavy nitrogen for what purpose?
A. So each generation of DNA would have a different weight to distinguish them by.
B. To determine how the bacteria functioned with a heavier element.
C. To see how the heavy nitrogen affected their DNA.
D. So each generation of protein would have a different weight to distinguish them by.
Answer:
D. So each generation of DNA would have a different weight to distinguish them by.
I took the test
Meselson and Stahl performed an experiment to find out the semiconservative property of DNA and to differentiate the DNA weight of alternative generation both scientists used heavy nitrogen. Thus option A is correct.
What is the semiconservative property of DNA?When a double-stranded DNA undergoes replication, it results in the formation of 2 double-stranded DNAs and each newly formed DNA has one parental DNA strand and one new DNA strand and this is the semiconservative property of DNA.
Heavy nitrogen of media will appear in the newly synthesized DNA strand so each generation of DNA would have a different weight . So option A is correct.
