According to evolutionary theory, behaviors that optimize survival and reproduction are favored by natural selection and therefore more likely to persist. How, then, can we explain the evolution of altruism, which is by definition costly to the self
Answer:
Altruism could be helpful for the survival of relatives
Explanation:
Altruism behavior is produced when an organism decreases its fitness in order to increase the chances of survival in other individuals in the population. It is believed that altruistic behavior could have evolved as an adaptation associated with the survival of relatives from the same family. In consequence, if this were the case, altruism could ultimately be considered as a selfish behavior because it aims at passing on of genes through the survival of relatives which could benefit with this behavior.

Which nerve is responsible for weakness in climbing stairs or jumping?
A. Tibial
B. Superior gluteal
C. Inferior gluteal
D. Obturator
E. Femoral
Answer:
C. Inferior gluteal
Explanation:
The inferior gluteal nerve has a rich concentration in the gluteus maximus muscle. This muscle is located in the hip region. These nerves are primarily responsible for the ability of the gluteus maximus to move and performs some functions during motion.
An example of such function involves the extension of the hip to the thigh in movements such as climbing stairs, hiking, squatting etc.
In a fluorescence recovery after photobleaching (FRAP) experiment, a fluorescently tagged membrane protein, A, shows very little recovery of fluorescence ten minutes after photobleaching, while membrane protein B shows a rapid increase in fluorescence after bleaching, recovering nearly 80% of its original fluorescent signal by ten minutes. Based on this information, which of the following statements can be made?
A. Proteins A and B interact with each other in a complex
B. Protein A is easily denatured,
C. Protein Bis diffusing in a more fluid membrane.
D. Protein Ahas faster mobility in the membrane.
Answer:
The correct answer is option C. Protein Bis diffusing in a more fluid membrane.
Explanation:
Fluorescence recovery after photobleaching or FRAP is a technique used to examine the portability of fluorescent particles with the help of fluorescence microscopy that have been utilized since the mid-70s to evaluate the dispersion or movements of molecules in the cell membranes of the cell.
Fluorescence Recovery After Photobleaching (FRAP) is a strategy for deciding the energy of dispersion in living cells (typically) utilizing fluorescence microscopy.
In the given experiment:
The diffusion coefficient of GFP vary, based on the localization of the protein
Protein B is freely diffusing, due to which recovery is very high compared to protein A.
Protein which is less diffusing shows a slower and less rate of recovery.
a medical reasearcher is testing a new experimental drug for a headache patients Group A consists of 100 participants who are given the new exprimental drug group B consists of 100 participants who are given a placebo or fake pill. Neither group knows which treatment they received Which is the control group?
Answer:
Group B... (the Placebo)
Explanation:
I say group B because the medical reasearchers are using group B to see the outcome and effects of the experimtal drug that they gave group A. So if in the end group A (given the experimental drug) has a better response to the headache after taking the pill then group B (given a fake drug) the medical reasearcher will know the effectiveness of the new drug.
Evaporative cooling is a product of evolution that has evolved in some organisms for use under certain environmental conditions. Circle the organisms or conditions below that you think are most likely to use evaporative cooling.
Answer:
In order to lower the temperature.
Explanation:
Mammals and birds uses evaporative cooling due to their high body temperature because this evaporative cooling removes the high temperature from the body. In this process, the water present in the body absorb all the extra heat and remove this extra heat from the body with change its state from liquid to vapors and the body's temperature cools down. This evaporative cooling is occurs in the process of sweating.
How does exponential growth differ from logistic growth? R‐selected species have exponential growth rates, whereas K‐selected species always experience logistic growth. Exponential growth occurs when the population is at its biotic potential, whereas logistic growth is limited by the carrying capacity of the environment. Exponential growth is expressed as doubling time, whereas logistic growth is expressed as a percentage change. Exponential growth occurs when a population is very large, whereas logistic growth occurs when a population is at its minimum viable number. Exponential growth results in a J‐shaped curve, whereas logistic growth results in an S‐shaped curve.
Answer:
Exponential growth occurs when the population is at its biotic potential, whereas logistic growth is limited by the carrying capacity of the environment.
Explanation:
A population that exhibits a logistic growth model, depends on density, the natality and mortality rate depends on the population size, which means that there is no independence between population growth and population density.When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.
If the population size, N, is inferior to K (N<K) the population can still grow. When N approximates to K, the population´s growth speed decreases. When N=K, the population reaches equilibrium, and when N is superior to K (N>K) the population must decrease in size because there are not enough resources to maintain that size.
The sigmoid curve represents the logistic growth model. At the beginning population grow slowly. In the exposed example this occurred when the small group of 10 foxes moved to the new environment, starting a new population. In the second stage, the population size increases rapidly. Probably this happened when foxes reached a number of 40 individuals. And finally, slow and gradually, the population reaches the equilibrium point, K, which depends on resource availability. This point belongs to the stage where food starts to become harder to find, and much of the living space is occupied.
A population that exhibits an exponential growth model increases in proportion to its size. The increase in the population size depends on the individual´s reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.This model is based on unlimited resource availability which means that there is no effect depending on density. There is no competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita and it is proportional to the population size.
Which of them is important in endurance race physical strength or emotional strength?
Answer:
Both
Explanation:
Endurance deals with how long you can do something that puts a physical strain on your body and not necessarily how much strain at once. That being said both physical strength and emotional strength play a big role in this. Physical strength is needed to be able to exert yourself and accomplish the initial task in the first place. While emotional strength is also needed in order to not give up and persevere as long as possible. Without will power (emotional strength) you will give up as soon as you are given the opportunity.

A change in genotype, but not in phenotype, is most likely due to _________.
A change in genotype, but not in phenotype, is most likely due to neutral mutation.
A mutation consists of a spontaneous and unpredictable change in the sequence of genes that make up the DNA of a living being.
A neutral mutation is one that has no consequences on the phenotype, that is, it has no effect on the observable characteristics of an organism.Neutral mutations has effects on the genotype because it generates a change in the order of nucleotides that creates triplets that code for equivalent amino acids as basic amino acids.Therefore, we can conclude that a neutral mutation does not affect the viability of the living being.

A two-year-old weighing 25.2 lb is admitted to the hospital with fever and diarrhea. Normally the child weighs 29.6 lb. How much fluid (in liters) needs to be replaced in the child's system?a. 1Lb. 1.75 Lc. 2 Ld. 4.4 L
Answer: C.) 2L
Explanation:
Given the question :
A two-year-old weighing 25.2 lb is admitted to the hospital with fever and diarrhea. Normally the child weighs 29.6 lb. How much fluid (in liters) needs to be replaced in the child's system?
Normal body weight if the baby = 29.6lb (pounds)
Weight of baby die to fever and diarrhea = 25.2lb(pounds)
Weight loss due to diarrhea and fever :
(29.6 - 25.2)lb = 4.4 lb
Amount of fluid needed to be replaced in litres = weight loss due to sickness
Then we need to convert 4.4lbs to Litre (L)
1 pound (lb) = 0.45359 liter (l)
4.4 lb = (4.4 * 0.45359) L
= 1.995796 L
= 2L
