O Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answers
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Respiratory distress syndrome (RDS) is a well-known breathing disorder that is common in premature infants. It happens when there is a lack of surfactant produced in the baby's lungs which is quite bad because surfactant enables babies to breathe when they are born by keeping the lungs expanded.
It is common in premature infants because the lungs only begin to produce surfactant in the third trimester so babies that are born prematurely did not get to produce sufficient quantities. If not treated immediately, brain damage could follow.

Which situation is the best example of secondary succession?
A) An organism survives a difficult winter
B) The population in an area remains the same
C) One species replaces another species in an ecosystem after a forest fire
D) Each of several species uses the same amount of resources
Answers
Answer:
The answer is C
Explanation:
Secondary succession often occurs after a disaster, the ecosystem is not as primary as the primary succession, so it will take shorter time to recover. New species will occur in this place, and rebuild a constant environment. C is exactly the situation.
Hope this will help❤️
The best example of secondary succession is when one species replaces another species in an ecosystem after a forest fire. The correct option is C.
What is secondary succession?Secondary succession is a type of ecological succession that occurs on substrates that already have soil, and at least some organisms residing on it, like a forest or a community that has been disrupted by wildfire, tornadoes, or hurricanes.
The secondary succession in an ecosystem happens when a primary community is destroyed, for example, by wildfire. In secondary succession, the soil, seeds, and rhizomes survived in the soil and provides the foundation for the new community that is about to develop.
The rate of secondary succession varies according to the time taken for the primary community to regenerate, the level of disturbance of the habitat, the availability of propagules, and the dispersal capability of the species involved.
Therefore, the correct option is C.

to differentiate between agarose gel electrophoresis and SDS-PAGE based on the following criteria:
2.2.1 Composition of gels
2.2.2 Dye used for staining
Answers
Explanation:
Agarose has a large pore size and is suitable for separating nucleic acids and large protein complexes. ... SDS-PAGE separates proteins primarily by mass because the ionic detergent SDS denatures and binds to proteins to make them uniformly negatively charged.
In this question we will differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.
Agarose gelThe gel matrix is created by dissolving a natural polysaccharide called dye-free agarose, which is derived from a type of seaweed, in a conductive buffer, in the approximate proportion of 1% to 3% agarose.
SDS-PAGEPolyacrylamide gel electrophoresis (PAGE) with sodium dodecyl sulfate (SDS). SDS-PAGE consists of a type of electrophoresis performed under denaturing conditions for the separation of proteins without dyes.
Whit this information, we can conclude that differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.

Describe the stages of invasion up to and including the spread stage. Also, include one barrier to could make
an invasion fail and briefly describe it.
Answers
Answer:
Introduction, naturalization, colonization, and dispersal or spreading.
Explanation:
There are four main stages of invasion i.e. introduction, naturalization, colonization, and dispersal or spreading. In the first stage, the specie is introduced in the environment, in the second stage the specie adopt the environment, in the third stage the specie started growth and make colonies to increase its population and in the last stage the specie disperse in the environment through different means and spreading of that organism occur. The failing of adaptation to the environmental conditions leads to the failing of invasion of a specie.
What is the biggest error, methodologically, in the following scientific study? "The goal of the study was to determine whether the ebola virus is as deadly in rhesus monkeys as it is in gorillas. I took a sample of four healthy rhesus monkeys and four healthy gorillas. The animals were a random mixture of sexes and ages. I arranged eight cages so that each animal would be in a separate cage, and I made sure there would be no contact among the cages that would allow transmission of the virus. Then I obtained a sample of the ebola virus from the National Institute of Infectious Diseases and injected all the monkeys and gorillas with the same size dose. At the end of four days, I noticed that all the gorillas were dead but only one of the monkeys was dead. An autopsy revealed that three of the four gorillas had died of ebola fever but that the fourth, nicknamed Curious George, had died of internal bleeding after swallowing the small pair of scissors that were left within reach of its cage. The dead monkey had died of ebola fever. At the end of two months there were no more deaths. I concluded that my dosage of the ebola virus is three times as likely to be deadly to gorillas as it is to rhesus monkeys, but I recommended repeating the study to see if the percentages of deaths due to ebola fever remained steady over a wide range of dosages of the virus."
Answers
Answer:
The sample obtained for the study is not enough. Also, a control group is not established thus making the study erroneous.
Explanation:
The total sample size of 4 specimens from each of the two groups does not qualify as an appropriate sample size for the generalization of the results. Furthermore, the mixing of different ages and genders is not suitable for this kind of sample.
Also, the control group is not established where healthy specimens are kept in a similar environment to factor out the effects of the environment and other components on the health/death of the animals.

Calcium is the most abundant mineral in the human body. Calcium ions are needed for bone mineralization and tooth health,
regulation of the heart rate and strength of contraction, blood coagulation, contraction of smooth and skeletal muscle cells, and
regulation of nerve impulse conduction. When blood levels of calcium get too high, the thyroid gland is stimulated to release
calcitonin, which initiates actions to lower blood levels of calcium.
Consider the role of calcitonin. ALL BUT ONE is the result of the release of calcitonin by the thyroid gland.
A)
inhibits osteoclast activity
B)
stimulates calcium uptake by the bones
stimulates the synthesis of vitamin D
