Answer:

False

Explanation:

because water molecules are polar and carbon dioxide molecules are nonpolar. Water molecules have a weaker attraction than carbon dioxide molecules.

Answer:

Yes

Explanation:

Because they have both living and non living characteristics so it is hard to classify them as they posses living characteristics as reproduction and others when inside the host and posses non living characteristics when outside the host

In microorganisms micro means small and organism means living ones, so those living ones which are not seen without the help of a microscope, are microorganism.

Viruses are obligate parasites and are very small in size. Viruses cannot live outside the host cells as they require host cell gene expression machinery to divide and perform metabolic reactions. Viruses remain inactive in the environment until found the host cells.

As viruses cannot qualify the criteria of living beings because they cannot survive separately in the evnironment,  that's why cannot be considered living organisms.

Mostly microorganisms are single-celled organisms like bacteria, fungi, and protozoa. Viruses are not considered microorganisms because they are nonliving outside the host body.

Answer:

Explanation:

Answer:

This question lacks options, the options are:

A. 1

B. 3

C. 6

D. 11

The answer is C. 6

Explanation:

pH of a solution refers to the concentration of hydrogen ions in that solution. A scale is used to measure pH of a solution.

* A pH value less than (<) 7 is said to be ACIDIC. The lesser the number, the more acidic

* A pH value of exactly 7 is said to be NEUTRAL

* A pH value above (>) 7 is said to be BASIC OR ALKALINE. The higher the number, the more alkaline.

According to this question, two solutions of equal volume with pH values of 2 and 12 respectively were combined. Based on the explanation of pH scale, the solution with pH 2 is said to be very ACIDIC while the solution with pH 12 is said to be very ALKALINE.

Hence, if this two solutions are combined, a neutralization will occur which will result to a solution with close to neutral pH (7). In the above options, 6 is the closest pH value to NEUTRAL and hence, the most likely pH of the resulting solution.

Answer:

Increases the pressure in the thoracic cavity

Explanation:

During pulmonary ventilation, relaxation of the diaphragm and external intercostals increases the pressure in the thoracic cavity and air flows out of the lungs.

Pulmonary ventilation involves the exchange of air in the body. The exchange mainly takes place between the lungs and the the blood. When the lungs take in oxygen it distributes it to other parts of the body after which the byproduct is expelled in the form of Carbon dioxide.

The diaphragm and intercostal muscles are found close to the chest(thoracic) region such that when air is expelled it produces a similar effect such as relaxation of the diaphragm which also makes the chest muscles go down and exert pressure. This mechanism aids the expulsion of Carbon dioxide from the lungs.

Answer:

Protein digestion begins in the mouth

Fat digestion begins in the stomach

Once a protein supply reaches your stomach, hydrochloric acid and enzymes referred to as proteases spoil it down into smaller chains of amino acids. Amino acids are joined collectively through peptides, that are damaged through proteases.

Fat digestion starts offevolved withinside the stomach. Some of the byproducts of fats digestion may be immediately absorbed withinside the stomach. When the fats enters the small intestine, the gallbladder and pancreas secrete materials to in addition spoil down the fats.

The approaches of digestion encompass six activities: ingestion, propulsion, mechanical or bodily digestion, chemical digestion, absorption, and defecation. The first of those approaches, ingestion, refers back to the access of meals into the alimentary canal thru the mouth.

Thus it is well explained.

Answer:

At each intervertebral foramen, the dura mater extends between adjacent vertebrae and fuses with the connective tissue layers that surround the spinal nerves.

Explanation:

The dura mater is the outermost meninge. It is around the spinal cord and the brain, and it protects these organs.  In the spine, the dura mater extends between the intervertebral foramen. The intervertebral foramina are the areas between each vertebra that have spinal nerve projections. In these areas, the dura mater extends to seclude the space where the spinal cord is since it fusses with the tissue that is around each spinal nerve to stop the entrance of any pathogen to the spinal canal, which is the space that contains the spinal cord.

Actin produces thin contractile filaments within muscle cells,

Myosin produces the dense contractile filaments within muscle cells

Explanation:

Actin is a globular protein that makes actin filaments by arranging in the long spiral chain or produces thin contractile filaments within muscle cells. It is found in cell cytoplasm as well as in the nucleus in eukaryotic cells.

Myosin is a motor protein that produces the dense contractile filaments within muscle cells and plays role in generating movement and force from chemical energy.

Answer:

A plausible hypothesis is that deleterious germline mutations in sperm cells are removed by natural selection since sperms have to compete to fertilize the egg

Explanation:

Sperm cells need to travel through the cervix in order to reach the uterus and fertilize the egg. During this process (which is called 'fertilization'), approximately 300 million sperm cells have to compete in a race to reach an egg. During fertilization, the majority of sperm cells die off quickly because male germinal cells carry mutations that lead to abnormalities (e.g., many sperms have double heads, others no tail, etc). The sperm cells are considered to be physiologically weak because their normal functions can be easily disrupted by mutations and, simultaneously, they are under strong selective pressure to be selected during the sperm race. In consequence, deleterious germline male mutations are expected to be eliminated by natural selection, thereby sperms are selected before fertilization so only the strongest ones can compete in the race to fuse with the egg cell and thus develop one zygote.

Drug resistance only arises from an organism gaining the genetic information for the resistance from another organism.

Answer:

D. Adenosine DIPHOSPHATE

Explanation:

ATP is hydrolysed to ADP in the reaction ATP+H20->ADP +Pi + energy

When Adenosine Triphosphate is used, it breaks down into Adenosine Diphosphate.

Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atoms of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than does ADP. AMP contains one fewer phosphate group. Energy transfer used by all living things is a result of the dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and is a by-product of ADP.ATP is continually reformed from lower-energy species ADP and AMP. The biosynthesis of ATP is achieved throughout processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation, all of which facilitate the addition of a phosphate group to ADP.
