Answer:
Digestive System
Explanation:
The digestive system is responsible for the process of digestion, that is, processing and absorption of food in order to meet the needs of all cells. The proper functioning of this system is due to two important aspects:
- Compartmental, that is, as much as the various organs that make up this system are physically linked, they still have, within certain limits and harmony, independence of functioning. In other words, each organ will perform a particular function even though it is connected to other structures;
- Enzymatic, that is, the food will pass through the different organs and, as a result, will undergo the enzymatic action of different enzymes in each region.
A valid caveat is that during the digestion process physical and chemical changes occur with the food, which aims to create chemical structures and the ideal physical condition to be absorbed.

The combining form that refers to the male gland that encircles the upper end of the urethra is:
The combining form referring to the male gland that encircles the upper end of the urethra is 'prostat/o' which relates to the prostate gland. It is used in medical terminologies like 'prostatitis' and 'prostatectomy'.
Explanation:The combining form that refers to the male gland that encircles the upper end of the urethra is 'prostat/o'. This form is derived from the word prostate, which is the name of the gland in question. The word 'prostate' itself comes from a Greek word meaning 'one standing in front', referring to its location in the body. The prostate gland plays a crucial role in sexual functions and in the process of ejaculation.
For instance, in medical terminology, you may see this combining form used in words like 'prostatitis', which is inflammation of the prostate gland, or 'prostatectomy', which is the surgical removal of all or part of the prostate gland.

Relationship A is parasitism and Relationship B is competition.
Relationship A is competition and Relationship B is parasitism.
Relationship A is commensalism and Relationship B is mutualism.
Relationship A is mutualism and Relationship B is commensalism.
Answer:
Option (4).
Explanation:
Biological interactions are important among the organism that helps them to survive in their environment. Biological interactions may be harmful or useful for the organisms.
Mutualism may be defined as a type of interaction in which both the species are benefited from each other. Amy should include relationship A in mutualism. Commensalism may be defined as the type of interaction in which one species is benefited and other organism is neither benefited nor harmed the individual. The relationship B is involved in commensalism.
Thus, the correct answer is option (4).

Both euglena and Cyanobacteria are photosynthetic unicellular organisms found in pond water. The feature that distinguishes euglena from Cyanobacteria is the-
A. Ability to maintain homeostasis
B.presence of ribosomes
C.presence of nuclear membrane
The correct answer is option C, that is, the presence of the nuclear membrane.
Cyanobacteria is a phylum of bacteria that attain their energy via the process of photosynthesis, and are the only photosynthetic prokaryotes possessing the tendency to generate oxygen. As a prokaryote, they are devoid of the nuclear membrane.
Euglena refers to a single cell flagellate eukaryote. It comes under the class Euglenoidea. The species of Euglena are witnessed in salt water and in freshwater. Being a eukaryote, they possess nuclear membrane.
The difference between them is the presence of nuclear membrane in euglena.

While observing slides under a microscope, jack adjusts the microscopes mirror so that a circle of light can be seen. Which microscope is jack using?
Jack is likely using a compound light microscope, which uses visible light through lenses to magnify specimens. He's adjusting the mirror for proper lighting and may need to refocus the microscope after switching to a higher magnification lens.
If Jack is adjusting the microscope's mirror to see a circle of light, he is likely using an optical microscope, specifically a compound light microscope. This type of microscope uses visible light and lenses to magnify objects and is the most commonly used microscope in many scientific fields. The purpose of the mirror is to direct light up through the bottom of the stage where the slide is placed so that the object being viewed is illuminated. This light then passes through the objective lenses, which magnify the specimen. Jack might also be adjusting the light intensity to ensure adequate lighting for a sharp and clear observation.
When Jack switches from a 10X to a 40X objective lens, as described in Laboratory Exercises in Microbiology, he must re-focus using the fine adjustment knob and potentially adjust the light again to ensure the specimen is still in sharp focus under this increased magnification. With a compound light microscope, after focusing with the low power lens, one usually rotates the nosepiece to switch to a higher power lens and refocus using only the fine adjustment knob to bring out the details of the specimen.
Hydrogen bonding results in two processes which we see as ____ and ____
Answer:
Disassociation, polarization and attraction
Explanation:
In an hydrogen bond, the hydrogen act as partially positive atom while the other element to which it is bonded act as partially negative atom. This second element other than the hydrogen can be oxygen, fluorine, chlorine etc.
First the hydrogen bonds disassociates and polarizes thereby forming two poles one positive and the other one negative.
The positive poles now try to attract the negative pole of other molecule of the same substance or any other substance. The same happens with the negative pole also.
