explain the process (reflex action) that happens when you pull your arm away from an open flame. use steps to explain your answer. identify the receptor in the skin, the stimulus, the neurons,the effector(muscle) and the body's response to the stimulus.
Answer:
A reflex action is defined as an involuntary action of body in response to a stimulus, which protects the body from any harmful conditions including touching open flame.
A reflex action follows a sequence of action that helps in involuntary action, tha include the stimulus, receptor in the skin, the neurons (sensory, relay and motor neurons), the effector(muscle) and resposne of body to stimulus.
In the reflex action when a person pull his/her arm away from an open flame, the stimulus will be the hot flame that send a signal to the nervous system.
The sensory receptor found in the dermis or epidermis of skin called cutaneous receptors, senses the temperature change.
Then the sensory neuron comes in action which sends electrical impulses to a relay neuron (located in spinal cord) and relay neuron sends impulse to motor neuron.
Motor neuron sends that electrical impulses to a muscle which act as an effector which allows muscle to contracts to move hand away.
So, at the end the body resposnes to move hand aways from the open flame.
The surface of the villi in the small intestine is covered by a single layer of epithelial cells called enterocytes. Enterocytes absorb nutrients from the intestinal lumen as they move up the side of the villus. The enterocytes are shed from the end of the villus through apoptosis after 3 to 4 days. Consequently, new cells must be continuously supplied from the crypt and move up the villus. When a stem cell in the crypt divides, what are its immediate daughter cells
Answer:

You prepare an agar plate by spread plating & place an antibiotic disk in the middle of the plate. After incubating for a day at 37 degrees C, there are no bacteria on the plate. Which of the following is NOT a reasonable interpretation of what might have happened?
O The bacteria in the culture tube were already dead when you made the plate
O The medium used was defective and provided no nutrition for the bacteria
O The bacteria grew all over the plate but were then killed by the antibiotic
O The spreading tool was too hot when spreading the bacteria
Answer:
A.The bacteria in the culture tube were already dead when you made the plate
Explanation:
Antibiotics are the chemical substance used to kill or stop the growth of bacteria and some other microorganism.
Antibiotics are added to agar plate during experiment for the selection of only those bacteria with resistance to that antibiotic.
There can be several interpretation for the absence of bacteria such as:
The bacteria grows on the nutrients in the medium but due to defective medium they were unable to grow and die.It may also happen bacteria might have grown in all over the plate but due to the action of antibiotic, all the bacteria got killed.Tool used for spreading might kill bacteria as it was hot and bacteria may not be able to tolerate the excessive heat and die.Hence, the only not reasonable interpretation is bacteria in the culture tube were already dead when you made the plate.
So, the correct option is A.

e. The cell expends energy to transport materials into the cytosol.
Answer:
The correct answer is:
The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it. (d.)
Explanation:
Endocytosis is a type of active transport, where particles such as (large molecules, parts of cells, and even whole cells) are moved into cells.
The various types of endocytosis has a common feature of:
1. invagination of plasma membrane forming pockets around the target particle.
2. the pocket pinches off from original plasma membrane
3. forming a new intracellular vesicle containing the target particle.
The different types of endocytosis includes
a. pinocytosis (cell drinking): takes in extracellular fluids
b. phagocytosis (cell eating): large solid particles are taken in by cells
c. receptor-mediated endocytosis: here, receptor proteins on the cells surface, binds to complementary proteins on the surface of the target particles before endocytosis occurs.

What explains why populations fluctuate around the carrying capacity?
Answer:
In population ecology: Population fluctuation As stated above, populations rarely grow smoothly up to the carrying capacity and then remain there. Instead, fluctuations in population numbers, abundance, or density from one time step to the next are the norm.
The carrying capacity of an environment is the maximum population size of a biological species that can be sustained in that specific environment, given the food, habitat, water, and other resources available. In population ecology, carrying capacity is defined as the environment's maximal load, which is different from the concept of population equilibrium, which may be far below an environment's carrying capacity. The effect of carrying capacity on population dynamics may be modelled with a logistic function.
The populations fluctuate around its carrying capacity because it is very common even for a stable population to briefly exceed or dip below its carrying capacity.
The size of the population fluctuate due to some environmental factors, presence of predators, competitors etc.
Also reproductive lag time can also cause the population to exceed the carrying capacity temporarily.
What is carrying capacity?The carrying capacity of an environment is the maximum population size of organisms that can be supported by the ecosystem, given the food, mates, shelters and other resources available.
What is reproductive lag time?Reproductive lag time is the time required for birth rate to decline and the death rate to increase in response to resource limits.

4. Is predation a density-dependent or density-independent factor?
Answer:
The correct answer is density-dependent factor.
Explanation:
The factors whose influences on the growth or size of the population changes with the density of the population are known as the density-dependent factors. The availability of food, disease, predation, and migration are some types of density-dependent limiting factors.
One of the density-dependent factors in nature is predation, predation confines various populations. The population of the prey and the predator encircle towards each other, with the population of the predator somewhat lagging behind the population of the prey.
With the increase in the population of the prey, the predator gets more to eat, and thus the population of the predator increases. With the increase in the predator population, pressure imparts on the prey population and it starts to decline. The decline in the availability of the food eventually makes the population of the predator to decline. Therefore, it can be seen that both the population of the prey and the predator are affected by predation, that is, a density-dependent factor.

Within a population of butterflies, the color brown (B) is dominant over the color white (b) and 32% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam (teehee), calculate the following:
1. The percentage of butterflies in the population that are homozygous dominant
2. The number of heterozygous butterflies if the population contained 4,216 individuals
Answer:
48% Heterozygous of the population, 12% Homozygous dominant size.
Explanation:
Given the characteristics of its population,
Brown (B) predominates over white (b) color.
Recessive phenotype frequency (Q)= 40%= 0.4
According to the Hardy-Weinberg principle, the frequency is given by P and Q for a population with the dominant and recessive trait, where P+Q=1 preserves the equilibrium of the population allele.
So then, P = 1-Q
P=1-0.4=0.6
Heterozygotic butterflies = 2PQ
So, 2PQ= 2x0.6x0.4=0.48
That is, 48 percent of people are heterozygous
Homozygous dominant individual frequency = 1-(40 + 48) = 12 i.e. 12%
