Answer:
Hormones are chemical messengers that are secreted directly into the blood, which carries them to organs and tissues of the body to exert their functions. There are many types of hormones that act on different aspects of bodily functions and processes.
Answer: a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action.
Explanation: a regulatory substance produced in an organism and transported in tissue fluids such as blood or sap to stimulate specific cells or tissues into action. Hormones are chemical substances that affect the activity of another part of the body (target site). In essence, hormones serve as messengers, controlling and coordinating activities throughout the body.

Carbon dioxide is A a toxic gas produced by landfills. B produced by plants during photosynthesis. C needed by industry to power generators. D a greenhouse gas that traps heat in the atmosphere.
Answer:
The correct answer is option D, that is, a greenhouse gas that traps heat in the atmosphere.
Explanation:
A natural phenomenon in which the atmospheric gases captivates heat and permits Earth to retain enough solar energy to be livable is termed as the greenhouse effect. The greenhouse gases are the methane, carbon dioxide, nitrous oxide, and other gases, which gathers in the atmosphere and produces a heat-reflective layer that helps in trapping sunlight and keeps the Earth warm.
Of these greenhouse gases, carbon dioxide is the largest contributor to climate change. It is largely emitted at the time of burning fossil fuels like natural gas, oil, and other carbon-rich sources. Due to this, the level of carbon dioxide increases in the atmosphere resulting in the global phenomenon termed global warming.

What interactions are occurring that allow the water to move against gravity in capillary action? Select three options.
Answer:
Adhesion and surface tension
Explanation:
Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.
Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.
Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.

Which of the following heart block dysrhythmias is identified by a repetitious prolonging PR interval pattern after each blocked QRS complex
a) first degree heart block
b) second degree heart block type I
c) second degree heart block type II
d) third degree heart block
Answer: Option A.
first degree heart block
Explanation:
First degree atrioventricular block is a condition that is associated with electrical condition system of the heart in which the electrical impulses is conducted from the cardiac atria to the ventricles via atrioventricular node in a slow manner compare to the normal transmission.
It is first degree great block because it is characterized by prolong PR interval on an electrocardiogram (ECG) to more than 200 msec and atrial impulse is transfered to the ventricles, which lead to regular ventricular rate.
The PR interval of the surface ECG is measured from the start of atrial depolarization (P wave) to the commensement of ventricular depolarization or QRS complex.

What part of the body reproduces, grows, repairs itself, uses oxygen and nutrients, digests food, eliminates waste, produces heat and energy, and is able to move around
Answer:
A Human Cell
Explanation:
A Human Cell can do many things. All your organs, hair, skin, and muscle tissue are all made up of cells. Each human cell from a different part of your body can do and create different things. For example, the cells duplicate (which is reproduction), when it duplicates, it grows. It also uses the oxygen and nutrients for cellular respiration, when it takes in the oxygen and nutrients, it turns it into ATP, which is used to help your cells function. There are many other ways the human cell may relate to the question above. But here are some of the ways a human cell can be all those things.

A patient visits their doctor because they are having trouble digesting complex carbohydrates. The doctor learns that her patient runs 5-10 miles 5 days a week and drinks very little water. The doctor suggested (before doing any major testing) that the patient begin drinking plenty of water each day. The patient visits the doctor a week later and has no problems with digestion. Why did the doctor suggest such a simple change in habit for her patient?
Answer:
porque el paciente corre una gran distancia pero no toma mucha agua, lo que hace que este se deshidrate, entonces al cambiarlo este se hidrataría mejor ayudando a su condición fisisca

of mosquito bites is counted after 2 hours.
o the independent variable is the 2 hour time and the dependent variable is the number of
mosquito bites
o the independent variable is the number of mosquito bites and the dependent variable is the
repellant
the independent variable is the repellant and the dependent variable is the 2 hour time
the independent variable is the repellant and the dependent variable is the number of mosquito
bites
Answer:
Dependent variable: Number of bug bites
Independent variable: Sprayed arm
Control group: Arm not sprayed.
Experimental group: Sprayed arm
Explanation:
If you know the definitions for the independent variable, dependent variable, control and experimental group in a problem than it would be less complicated to figure out what they are in any given example. So, here are the definitions:
Independent variable: the factor that you change
Dependent variable: the factor that is measured
Control group: the factor that is kept the same
Experimental group: the group in an experiment that receives the variable being tested

Which of the following sustainable farming practices allows farmers to rely on their own water supply, rather than bringing in water from different locations? using wells crop rotation drip irrigation using insecticide
Answer:
drip irrigation
Explanation:
The correct answer would be drip irrigation.
It is a small scale irrigation system that is usually set up to minimize water usage compared to other forms of irrigations. The system consists of different pipes that start from the water source and networks to the stands of plants. Control valves also exist and these ensure that water slowly drips directly to the root of plants. The drip could be either from the above or below the ground surface.
Due to the efficiency associated with dripping water directly to the root of plants which is where it is primarily needed, the drip irrigation system requires minimal water supply and is sustainable.

what would be the affect on pcr reaction, if primers are not added in the reaction?
Answer:
In absence of the primer the reaction lacks a primer template junction, and thus a free 3′-hydroxyl group will cause the reaction to fail.
Explanation:
In the PCR reactions primers are used to bind to ssDNA template hybridize itself and define the segment or part of the sample that will be amplified. This hybridize template makes the primer template junction.
If primers not added this junction would not be created then the enzyme DNA polymerase cannot make new DNA due to there is no free 3′-hydroxyl group which is essential to bind with the first deoxynucleotide.
Thus, In absence of the primer the reaction lacks a primer template junction, and thus a free 3′-hydroxyl group will cause the reaction to fail.
On your laboratory test, you are presented with a mollusc that has a closed circulatory system. You know immediately that it must belong to the class ________.
Answer:
Cephalopoda
Explanation:
Cephalopods are the mollusk that has a closed circulatory system by simple circulation. The heart is located in the pericardic cavity and it is divided into two auricles and one ventricle. From the ventricle, the anterior aorta goes forward the head and the posterior aorta goes forward the visceral mass. The anterior aorta branches into many branchial arteries. All of them get united again in the head, in one cava vein from where the blood returns to the posterior extreme. This vein introduces into the pericardic cavity and brunches into two renal veins near the nephridium. Each branch penetrates into a nephridial sac and passes through the muscular branchial heart before it enters the gills. Blood passes from the ventricle to the branchia through many vessels. In the branchia, the blood gets oxygenated again and returns to the auricle. The posterior aorta irrigates the gonads and the mantle, and from the posterior extreme of the body, blood goes forward to the anterior body region through two veins that join the renal veins that flow into gill hearts.
