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.
Which of the following occurs during artificial cross pollination? A. A different plant species is used to pollinate another plant. B. The plants reproduce sexually by self pollination. C. The scientist completely controls the transfer of pollen from one flower to the stigma of another.
Answers
Answer:
c
Explanation:
its artificial= done by humans
During artificial cross-pollination, the scientist completely controls the transfer of pollen from one flower to the stigma of another.
What do you mean by Cross-pollination?Cross-pollination may be defined as a type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.
Any artificial thing requires the interference of human activity. This activity by human increase the chance of those who give better productivity in every aspect.
Therefore, during artificial cross-pollination, the scientist completely controls the transfer of pollen from one flower to the stigma of another.

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.

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

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 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.

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.

In your post, discuss ONE Neanderthal or Denisovan gene that is currently found within our species. Tell us about the gene and its function. Explain what it does for us. (Make sure you give a citation.) Explain in your own words any possible advantages that your Neanderthal or Denisovan gene might have. Make sure you give in informed opinion that is grounded in your research. Caution: Make sure that your chosen genetic variant is not simply a result of common ancestry. For example: FOXP2 is a gene that Neanderthals and Sapiens share because of common ancestry. Verify that the genetic variant that you are looking at is actually derived from Neanderthals, Denisovans or another species. You will have to respond to two other student posts. Make sure you cite your work.
Answers
Answer:
It has been shown that many microRNAs (miRNAs) were differentially expressed in Neanderthal and Denisovan genomes.
Explanation:
MicroRNAs (miRNAs) genes encode for RNA regulatory sequences capable of modulating gene expression patterns, thereby they play critical roles in evolution and development. It has been proposed that these miRNAs might control the expression of TRAPPC9, GRID1, PRDM16, NAV2, SorCS2, CAMTA1, and ASIC genes, which are involved in neurocognitive developmental functions.

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.

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.
