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.

Answers

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.

Replanting trees on a bare hillside is an example of

(A) conservation and afforestation
(B) preservation and conservation
(C) restoration and preservation
(D) reafforestation and restoration​

Answers

Answer:

(D) Reafforestation and restoration

Explanation:

Replanting trees in helping to "re-forest" the hill and restore it to how it was before.

Replanting trees in a place where trees used to exist is an example of reafforestation and restoration.

Afforestation means to create a forest (trees) where they do not exist before.

Reafforestation, on the other hand, means to create a forest (by planting trees) to an area that used to be a forest but has been removed due to one reason or another.

Similarly, restoration means restoring an area to what it used to be. Forest restoration is the practice of restoring a forest that has been modified by natural or anthropogenic processes to its old self.

Thus, replanting trees on a bare hillside is an example of reafforestation and restoration.

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

Answers

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%

Answer:

C. 0.48

c. The cell membrane pinches off to form an extracellular vesicle joined to the cell by filaments.

d. The cell membrane engulfs a particle in the cytoplasm and forms a vesicle around it.

e. The cell expends energy to transport materials into the cytosol.

Answers

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.

4. Is predation a density-dependent or density-independent factor?

Answers

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.

Reptiles are a class of vertebrates made up mostly of snakes, turtles, lizards, and crocodilians. The options (A), (B) and (E) are correct.

What are the characteristics of reptiles?

Reptiles, as most commonly defined are the animals in the class Reptilia, a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates and rhynchocephalians.

Moreover, the major groups of living reptiles—the turtles (order Testudines), tuatara (order Rhynchocephalia [Sphenodontida]), lizards and snakes (order Squamata), and crocodiles (order Crocodylia, or Crocodilia)—account for over 8,700 species.

Therefore, the name "reptile" comes from Latin and means "one who creeps". All living reptile species are cold blooded, have scaly skin, and lay cleidoic eggs. They excrete uric acid (instead of urea), and have a cloaca. A cloaca is a shared opening for the anus, urinary tract and reproductive ducts.

What is the advantage for birds of not having a bladder?

Answers

Answer:

Explanation:

The urinary bladder is a flexible sac that can expand and contract and that holds urine.

Urea is excreted mainly by birds and it happens to be the main chemical in urine, without the water in it, the birds excrete just solid droppings instead of as a liquid.

Now, birds physiology is such that they have only one opening to get rid of their (solid) waste and they do not have a bladder.

What explains why populations fluctuate around the carrying capacity?

Answers

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.

what is the relationship between peripheral resistance and blood pressure ? between blood viscosity and blood pressure

Answers

Answer:

Peripheral vascular resistance (systemic vascular resistance, SVR) is the resistance in the circulatory system that is used to create blood pressure, the flow of blood and is also a component of cardiac function. When blood vessels constrict (vasoconstriction) this leads to an increase in SVR.

The relationship between BP and viscosity is such that, given a constant systolic BP, if blood viscosity increases, then the total peripheral resistance (TPR) will necessarily increase, thereby reducing blood flow. Conversely, when viscosity decreases, blood flow and perfusion will increase.

Anaerobic respiration happens in muscle cells and yeast cells.
The equation describes anaerobic respiration in muscle cells.
glucose ---> lactic acid
How can you tell from the equation that this process is anaerobic?
would the answer just be no co2 is produced?

Answers

Answer:

Am I think Co 2 will not be released but rather Glucose will be released

Explanation:

This is because

C6H12O6>2C5H5OH+2Co2 + Energy

there fore glucose is produced

From the equation "glucose → lactic acid," we can infer that the process is anaerobic. One way to determine this is by the absence of carbon dioxide (CO2) in the equation.

Glucose is entirely oxidized to create carbon dioxide, water, and energy during aerobic respiration, which takes place in the presence of oxygen.

Yet, in anaerobic respiration, the lack of oxygen causes an incomplete breakdown of glucose, producing additional byproducts such lactic acid as a result.

Muscle cells have the ability to transition to anaerobic respiration in order to satisfy their energy needs when there is insufficient oxygen.

Muscle cells have the ability to engage in anaerobic respiration, which produces ATP (adenosine triphosphate), the cellular energy currency, by partly metabolizing glucose, during hard exercise or when oxygen supply is constrained.

During anaerobic respiration, lactic acid builds up in muscle cells, which can lead to exhaustion and pain.

As a scientist working for an anti-bioterrorism task force, you are asked to evaluate some biological samples for the presence of Yersinia pestis, the organism that causes the plague. After confirming that the samples do contain Y. pestis, you instruct your team to begin sequencing the strain. Since the genome sequence of Y. pestis is already known, why would sequencing this strain be useful?

Answers

Answer:

To gather relevant knowledge about their origin and to determine if the strain has been genetically modified.

Explanation:

A researcher researching with the anti-bioterrorism working group, they are required to assess certain blood specimens only for existence of Yersinia pestis, the organisms which causes the disease.

Since verifying that perhaps the varieties showed Y. Pestis, they are instructing their group to start sequence alignment the strains. So, this is to collect specific knowledge about their origin and to assess if the strain has also been genetically modified.
