Answer:

Explanation:

in the given sample of blood concentration of all the comonents is normal. the concentration of urea is 2.6 to 6.5 mM, concentration of carbon dioxide is 23-29 meq/L, while concentration of glucose ad oxygen are 0.9 g and 20.1 ml respectively.

Blood is the component of the circulatory system which is essential for the transport of gases and excretion of waste products. It is crucial for nutrient and oxygen supply to the body.

The concentration of oxygen was 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

Therefore, the normal concentration of blood substances is oxygen 95.6 mmHg, carbon dioxide 39.3 mmHg, Sugar 115.5 mg and urea 13 mg.

✓ nitrogenous bases in RNA

O there is no order in amino acids

O nitrogenous bases in DNA

Explanation:

Protein synthesis is the process in which cells make proteins. Translation occurs at the ribosome, which consists of rRNA and proteins. In translation, the instructions in mRNA are read, and tRNA brings the correct sequence of amino acids to the ribosome.

Answer:

B

Explanation:

Answer:

1. Receptor (nociceptor).

2. Afferent neurons.

3. Spinal cord.

4. Motor neurons.

5. Efferent neuron (effector).

Explanation:

In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).

To solve this, we must be knowing each and every concept related to speed, acceleration and its calculation. Therefore, the given statement is false.

Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.

Acceleration is defined by the rate at which an object's velocity changes with respect to time. When an object's velocity changes, it is referred to as accelerating or to have acceleration. Speed does not include the direction of an object's motion. Acceleration include the direction of an object's motion.

Therefore, the given statement is false.

Answer:pH meter

Explanation:

Answer:

C

Explanation:

The experimental and control group differ by only one factor for a scientist, and that is the independent variable.

A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.

The correct option is, therefore, C.

Answer:

Mitochondria and chloroplasts have their own DNA

Mitochondria and chloroplasts are surrounded by two membranes

Mitochondria are about the same size as most bacteria

Explanation:

The endosymbiotic theory, also known as symbiogenesis, is a theory that explains how eukaryotic organisms have been formed from prokaryotic cells. This theory holds that eukaryotic organisms originated from prokaryotic organisms that engulfed another prokaryotic cell, creating thus an organism with multiple membranes. In consequence, eukaryotic organelles, including mitochondria and chloroplasts, would have evolved from these prokaryotic endosymbionts. Moreover, both mitochondria and chloroplasts contain their own genes which are localized in a circular chromosome, thereby supporting an endosymbiotic origin of both organelles. Finally, bacterial cells have 1 to 10 microns in length, while mitochondria have a similar size, thereby also supporting an endosymbiotic origin of this organelle.

Answer and Explanation:

Petroleum and coal are fossil fuels.  The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

If the water waste is microchips is reduced then gallons of water will be saved. Also, devising engineering mechanism to reuse water in chip manufacturing industry will further reduce the water waste.

Hence, option D is correct

Protein markers react with specific antibody which are proteins found in the immune system.

Immune system generally produces antibodies to protect the body from foreign invaders (antigen) such as bacteria, viruses or pollen.

Proteins produced by the body immune system from the stores of immunoglobulin protein is known as Antibodies.

Antibodies works by recognizing and latching onto antigens in order to remove them from the body.

The correct answer is Protein markers react with specific antibody in the body.

Answer:

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

Answer:

a. It's a carrier protein doing facillitated diffusion

Explanation:

Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.

The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.
