Why is a sound wave a mechanical wave?
Answer:
a sound wave moves through air by displacing air particles in a chain reaction, sound energy is associated with vibrations created by a vibrating source, that requires a medium to travel, which makes sound energy a mechanical wave
Explanation:
hoPE that helped :)
Answer:
Mechanical waves move "things"...they require a medium (whose molecules are the "things") to transmit their energy. Sound uses air molecules most of the time. It can use water molecules as well.

Answer:
Which description belongs in the area marked Z? Protection.
Explanation:
Have a great summer.
Herding is refer to as the act of bringing individual animals together into a group, maintaining the group, and moving the group from place to place or any combination of those. The description belongs in the area marked "Z" is foraging. Thus, the correct option is C.
What is flocking?A flocking is refer to as the large number of birds, especially those gathered together for the purpose of migration. For example, a large number of animals, especially sheep or goats kept together and migrate.
Foraging behavior includes all the methods by which an animal acquires and utilizes sources of energy and nutrients. This also includes the location and resources consumption, as well as their recapture and storage, within the context of the larger community.

Hyperglycemia (elevated blood sugar levels), such as would happen in diabetics, can damage the glomeruli.
a. True
b. False
Answer:
True
Explanation:
Hyperglycemia which means high Glucose level in the blood as a result of lack of insulin can damage the glomeruli. This interfere with the function of the glomeruli. Normally glomeruli fiters blood and remove nutrients to form urine but hyperglycemia will affect it's negatively and will make protein to leak from the blood into the urine. This can also lead to glomeruli called glomerulosclerosis.

Just like Earth, some of the planets in our solar system are also made of rock. Do you think the rocks on these planets transform?
Answer:
Yes.
Explanation:
Yes, I think the rocks on the planets transform which are closer to the earth such as Mercury, Venus, Earth, and Mars because of high temperature of the planets while on the other hand, the gas giants such as Jupiter, Saturn, Uranus, and Neptune have no transformation of rock due to their lower temperature of the environment as well as the soil so the rocks can't transform from one form to another form of rock.
An enzyme that breaks DNA, dispels the tension, and reseals the strand ahead of a DNA replication growing fork is called a(n):
Answer:
Topoisomerase
Explanation:
Topoisomerases are enzymes that produce changes in the topology of the DNA during replication, transcription, traduction, or reparation processes. They can cut one or both strands and in order to relieve torsional stresses in the supercoiled structure of DNA. With this, they help to maintain the chromosome's integrity. There are two types of topoisomerases: topoisomerase I (it cuts only one strand of DNA) and topoisomerase II (it is able to cut both strands of DNA).

stay safe healthy and happy..g In transcription, the 3'-hydroxyl group of the growing RNA strand: Group of answer choices NONE OF THESE binds to the 5' ribose. attacks the outermost phosphorous group of the incoming nucleotide. ALL OF THESE attacks the 5' hydrogen of the incoming nucleotide. interacts with a positively charged metal ion in the active site.
Answer:
attacks the outermost phosphorous group of the incoming nucleotide.
Explanation:
Transcription is the biological process where RNA is formed. As you may already know, RNA is an extremely important nucleic acid for genetic processes and the production of proteins. The transcription has three steps that are called start, elongation and end. In the elongation phase, the RNA strand is growing, at this time, RNA polymerase, which is the enzyme responsible for RNA elaboration, places the nucleotides, in the RNA strand, in the 5' - 3' direction. This enzyme causes the hydroxyl, which makes up the nucleotide at the 3' end of the forming RNA, to attack the phosphorus present in the incoming ribonucleotide.

Answer:
Skin contains tightly packed cells.Skin is tough, flexible, and waterproof.You cough when a pathogen enters your mouth.You sneeze when a pathogen enters your nose.Explanation:
The physical barriers of the immune system prevent infections since they stop or expel any pathogen that enters the body. The skin with its cells tightly packed and characteristics, the endothelia, and mucous membrane, like the one in our nose, are physical barriers. They stop antigens from infecting our body since they can remove them by sneezing, coughing, or shedding.

An Inflammatory response typically includes: Group of answer choices increased activity of phagocytes in an inflamed area inhibiting the release of white blood cells from bone marrow release of substances to decrease the blood supply to an inflamed area reduced permeability of blood vessels to conserve plasma
Answer:
increased activity of phagocytes in an inflamed area
Explanation:
An inflammatory response is the way the body defends itself against attacks by microbes, physical or chemical agents. In other words, this is how organisms defend and inhibit damage from attacks. The inflammatory response allows high phagocyte activities in the inflamed area. Phagocytes are immunity-related cells that attack foreign and invasive substances, bacteria and dead cells.

g in sickle cell anemia, there is a mutation in the beta subunit of hemoglobin where a glutamic acid is replaced with valine. How would that change affect the molecule
Answer and explanation:
Sickle cell anemia is a type of anemia that occurs because of a mutation in the HBB gene, which codifies for the beta subunit of hemoglobin, producing an abnormal beta-globin called Hemoglobin S o HbS. This anomalous beta subunit is a product of the replacement of the amino acid glutamic acid by the amino acid valine at position 6, resulting in a beta-globin that forms a long and rigid molecule turning red blood cells shape into a sickle one, condemning erythrocytes to a premature death (which will cause the anemia). Another complication patients with sickle cell anemia can have is the blocking of blood vessels because of the abnormal and rigid shape of their red blood cells.
how does phagocytosis occur in the lungs?
Answer:
Phagocytic defense in the normal lung is shared principally by two kinds of cells - alveolar macrophages that reside on the air surface and roam the alveoli and PMNs that circulate in the intravascular space or are stored transiently in areas adjacent to the capillary-alveolar interface (marginated in capillaries)

The flying squirrel of North America closely resembles the flying phalanger of Australia. They are similar in size and have long, bushy tails and skin folds that allows them to glide though the air. The squirrel is a placental mammal, while the phalanger is a marsupial. These close resamblances, even though genetically and geographically separarted by great distances, can best be explained by
Answer:
This can be explained by convergent evolution.
Explanation:
The similarities between the two animals presented in the question above can be explained by means of convergent evolution. This type of evolution refers to living beings that have characteristics in common, even though they do not have the same point of origin, that is, even though they do not have a common ancestor. In this case, the similarities between these beings are not based on genetic inheritance, but were established through the influence of the environment in these two beings, which ended up changing in similar ways. Convergent evolution is created through natrual selection and environmental pressure on individuals, regardless of their genetic makeup.
