The food sources that would be the safest are mushrooms, fruit, and berries.
What do you mean by Biomagnification?Biomagnification may be defined as the process by which a compound such as toxins, pollutants, etc. increases its concentration in the tissues of organisms as it travels up the food chain.
Mushrooms, fruit, and berries are present at the lowest level of the trophic level because they are autotrophs. Due to their position, they contain the lowest amount of toxins in them, and hence are more safest.
Therefore, the food sources that would be the safest are mushrooms, fruit, and berries.

The cardiovascular system is composed of two circulatory paths: pulmonary circulation and systemic circulation.
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the
A. left side of the heart where it is pumped to the lungs for oxygenation
B. lungs where blood picks up oxygen and returns to the left side of the heart
C. lungs where blood picks up oxygen and returns to the right side of the heart
D. lungs where the blood picks up oxygen and transports it to the tissues of the body
Answer:
B. lungs where blood picks up oxygen and returns to the left side of the heart.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
The cardiovascular system comprises of two circulatory paths:
I. Pulmonary circulation.
II. Systemic circulation.
Pulmonary circulation transports deoxygenated blood from the right side of the heart to the lungs where blood picks up oxygen and returns to the left side of the heart.
The pulmonary circulation loop is mainly supported (powered) by the right atrium and right ventricle.
Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

In cellular respiration, the energy for most ATP synthesis is supplied by:
A. High energy phosphate bonds in organic molecules
B. A proton gradient across a membrane
C. Converting oxygen to atp
D. Transferring electrons from organic molecules to pyruvate
E. Generating carbon dioxide and oxygen in the electron transport chain
Answer:
B. A proton gradient across a membrane.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.
In cellular respiration, the energy for most ATP synthesis is supplied by proton gradient across a membrane.
This ultimately implies that, most adenosine triphosphate (ATP) is formed due to the net movement of protons against a concentration gradient in the electron transport chain.
Explain how meiosis results in UNIQUE cells.
Meiosis is a reduction division in which the number of chromosomes in the parent cells is halved to the daughter cells.
Meiosis is the process such as:
Meiosis occurs in the reproductive cells of humans. Meiosis transmits genetic information from parent to offspring. Meiosis is the characteristic feature of sexual reproduction. The male and female gamete fuse to give rise to a newly formed combination of the daughter cells.Meiosis results in the recombination of male and female gametes, which results in the independent assortment of the genes.
Thus, meiosis always results in new variations and creates genetic diversity.

Jill has quite a menagerie of pets and she regularly has to deal with minor animal injuries. So when Johnnie, her rooster, spikes Jessie, her collie, on the muzzle with one of his long leg spurs, Jill knows what to do. She reaches for the hydrogen peroxide and thoroughly floods Jessie's puncture wound with the liquid. Jill observes, as always, that the hydrogen peroxide causes heavy fizzing at the site of the wound. She repeats the procedure several times a day over the next week, carefully inspecting the wound for signs of infection. The injury heals without complications and Jessie has a new respect for roosters.
a) What is hydrogen peroxide and how does it help to reduce the infection?
b) Why is hydrogen peroxide especially useful for treating puncture wounds?
c) What causes the fizzing associated with hydrogen peroxide use?
Answer:
a.) Hydrogen peroxide are highly reactive oxygen compounds used as an antiseptic
b.) Used in treating punctured wounds due to the nature of the wound which helps microorganisms to thrive.
c.) Fizzing associated with hydrogen peroxide use is due to presence of the enzyme catalase.
Explanation:
Hydrogen peroxide is a chemical compound which is made up of two hydrogen atoms and two oxygen atoms. It is powerful oxidizing agent which takes part in biological reactions. This is possible as it can remove electrons from other biological molecules which can damage other cellular components. It is used an an antiseptic to reduce infection because, being a powerful oxidizing agent, it has the ability to react with cell wall of these microorganisms through removal of electrons thereby causing damage to it.
Punctured wounds are narrow in structure which allows obligate anaerobic organisms to thrive because of reduced oxygen flow in the wound. Hydrogen peroxide can effectively eliminate these organisms which are most likely to cause infection in that site because they lack the enzyme called catalase.
Catalase is an enzyme which is present in living cells except obligate anaerobic organisms. It converts hydrogen peroxide into water and oxygen. The fizzing noticed by Jill while cleaning the wound with hydrogen peroxide is due to the catalase in Jill's own cells which converts the hydrogen peroxide to water and oxygen. When oxygen is given off, fizzing reactions are seen at the surface of the wound.

What are vascular plants?Vascular plants are a group of plants that have specialized tissues for conducting water, minerals, and nutrients throughout the plant. These specialized tissues, called vascular tissue, consist of xylem and phloem.
Xylem is a type of vascular tissue that is responsible for transporting water and minerals from the roots to the rest of the plant. It consists of tubes made of dead cells with thick cell walls that form a continuous network throughout the plant.
Phloem is another type of vascular tissue that is responsible for transporting sugars and other nutrients throughout the plant. It consists of tubes made of living cells that are arranged in a circular pattern around the xylem.
Vascular plants are important because they are able to grow to larger sizes than non-vascular plants due to their ability to transport water and nutrients throughout the plant. Examples of vascular plants include trees, grasses, and flowers.

Darwin and Wallace both observed greater species richness in the tropics than in Europe, but neither of them had a good explanation for why. One of the best-supported modern-day hypotheses to explain this pattern is that mutation rates are higher in the tropics than in temperate latitudes. Why would higher mutation rates lead to greater species richness
Answer:
Mutation shows the species energy relationships, tropics are more rich with energy as compared to the temperate europe.
Explanation:
The rate of species evolution is defined by the type of environment or the natural surroundings it lives in. Mutations Can affect organisms by making changes in their physical characteristics. Such can impact their DNA code and may even lead to death in many. The richness of species in the tropics is due to the more warmer and humid climates. They are suited to the development and germination of certain bacterias and have certain climatic phenomena.Which best describes a method of obtaining energy that may cause changes in

You are studying ion channels and have set up model lipid vesicles containing the three following transporters:
1. a Na+ /H+ antiporter driven by the Na+ concentration gradient.
2. The common 3Na+ /2K+ pump.
3. K+ leak channels. The experiments are designed such that all three transporters are oriented in the model lipid bilayers in the same direction they would be in the plasma membrane of a cell and that concentration gradients in vitro mimic the concentration gradients experienced by cells (e.g., the extracellular Na+ concentration is similar to the concentration outside of the vesicle whereas the concentration in the lumen of the model vesicles is similar to intracellular Na+ levels).
Required:
a. Draw the arrangement and ion flow of the three types of transporters in the model membranes.
b. What do you predict will happen to the pH of the vesicle lumen if you treat the model membranes with the drug oubain that impairs function of the 3Na+/2K+ pump? Briefly explain your answer in terms of what happens with each transporter.
Answer and Explanation:
a) you will find the arrangement and ion flow of the three types of transporters in the model membranes in the attached files.
K+ leak channels are channel proteins that allow K⁺ to leave the cell in favor of its concentration gradient. It keeps a stable equilibrium by taking out K⁺ that the 3Na+ /2K+ pump brings into the cell. Any alteration in the pump leads to an alteration in the leak channel functioning. Na+ /H+ antiporter is an integral membrane protein, and a secondary transporter is responsible for the interchange of H+ and Na+ through the membrane with no use of energy. It regulates pH within the cell. It responds to the Na+ and H+ concentration gradient, determined by the 3Na+ /2K+ pump. An alteration in the pump functioning produces a change in the Na gradient and consequently affects the antiporter interchange action. 3Na+ /2K+ pump is an integral protein that transports K+ and Na+ against the electrochemical gradient. A significant amount of energy is used to make the pump function. It brings K+ into the cell and takes Na+ out of it. It keeps the membrane potential and the electrochemical gradient constant. The pump function is associated with the leak channels and the antiporters function.Under normal conditions, the cell interior has a lower pH than the exterior. The K+ concentration is higher in the interior, while the Na+ concentration is higher in the cell exterior. The interior of the cell is always more electronegative than the cell exterior.
b)
The drug ouabain inhibits the pump. It impedes the Na+ exit and the K+ entrance. It occurs a sharp increase in the Na+ intracellular concentration, which influences the Na+ /H+ antiporter that changes the ions´ direction, taking out Na+ and bringing in H+ to compensate the intracellular Na+ excess. There is also a decrease in the leak channel function, which does not allow K+ to leave the cell.
Whenever the pump is inhibited, there is an increase in the intracellular pH, because Na+ concentration increases in the interior.

Answer:
C: Gregor Mandel
A genetic engineer wants to isolate a gene from a scorpion that encodes the deadly toxin found in its stinger, with the ultimate purpose of transferring this gene to bacteria and producing the toxin for use as a commercial pesticide. Isolating the gene requires a DNA library. Should the genetic engineer create a genomic library or a cDNA library
Answer:
The correct answer is - Yes, the genetic engineer should create a genomic library or a cDNA library.
Explanation:
mRNA isolated from the toxin extracted from the venom gland of the scorpion to create a cDNA library. The cDNA sequence is reverse transcribed by the mRNA that lacks the introns as prokaryotic organisms such as bacteria cannot splice introns.
If the engineer wants to express the toxin in bacteria then he required a cDNA sequence as a genomic clone can not use to clone for making proteins. mRNA should be isolated from the venom gland so it can synthesize cDNA library enriched with toxin protein sequence.
