explain the role of diaphragm in the process of breathing
Answers
Answer:
The diaphragm muscle contacts and relaxes to force the intake and expulsion of air from the lungs.
Explanation:
The diaphragm is a large, dome-shaped skeletal muscle. It is very thin, and is located at the base of the chest just above the abdomen. It plays a very important role during respiration or breathing by forcing the intake and expulsion of air from the lungs.
During inhalation, this muscle contracts, and flattens- in the process, a vacuum is created, effectively pulling air into the space. In exhalation the muscle relaxes, and is no longer flattened, this reduces the volume of the region, forcing air out of the lungs. These contractions occur rhythmically and continuously.

Pesticides are the chemicals used to prevent the damage if crops against harmful small insects or other small organisms. These chemical agents can either kill the pests or slow their growth to a great extent. Pesticides can be of three types: insecticides, fungicides and herbicides.
Reliability check in case of pesticides can be defined as the tests and surveys performed to check for their effectiveness. It is in simple terms a quality check. Reliability check for pesticides are very important because if these pesticides are hazardous, they can cause chronic illness in humans after the consumption of such crops.

The cells of the yellow dung fly contain 5 pairs of autosomal chromosomes and one pair of sex chromosomes. Upon completion of Meiosis II, how many chromosomes will each yellow dung fly gamete contain?
A. 5
B. 6
C. 10
D. 12
E. 24
Answers
Answer:
12
Explanation:
6 chromosomes. Each gamete will contain half the number of chromosomes compared to the parent cell after Meiosis II.
Option (B) is correct.
During Meiosis II, the number of chromosomes in each gamete is halved compared to the parent cell. In the case of the yellow dung fly, which has 5 pairs of autosomal chromosomes and one pair of sex chromosomes, the total number of chromosomes is 2*(5+1) = 12.
However, Meiosis II separates sister chromatids, resulting in the formation of four haploid daughter cells (gametes) with half the chromosome number of the parent cell. Therefore, each yellow dung fly gamete will contain 12/2 = 6 chromosomes.
The options given in the question are not consistent with the expected outcome. The correct answer should be B. 6 chromosomes, as the gametes will have half the number of chromosomes as the parent cell after Meiosis II.

Organisms that obtain their energy from producers or other consumers are heterotrophs.
What is heterotrophs ?An organism is referred to as a heterotroph if it consumes other plants or animals for food and energy. Its origins are in the Greek words hetero, which means "other," and trophe, which means "nutrition." Autotrophs and heterotrophs are two general classifications of organisms depending on how they receive energy and nutrients.
In contrast to heterotrophs, which cannot produce their own food and must rely on autotrophs for sustenance, autotrophs are organisms that create their own food through the process of photosynthesis.Humans and all other mammals, fish, birds, insects, and more basic living forms like bacteria and fungi are examples of heterotrophs.Learn more about Heterotrophs here:

Water makes up approximately 60% of the human body and plays a vital role in regulating body temperature. Which property of water allows it to prevent large fluctuations in body temperature?.
Answers
Water makes up approximately 60% of the human body and plays a vital role in regulating body temperature. Option D. Water has a high capacity for heat, preventing large fluctuations in body temperature.
Body temperature is described by way of the amount of heat had to increase the temperature of 1 gram of a substance by degree Celsius (°C). Water has a high unique heat, which means it takes extra strength to grow the temperature of the water as compared to other materials.
Water has the unique ability to dissolve many polar and ionic materials. this is essential to all living matters due to the fact, that as water travels via the water cycle, it takes many precious vitamins.
The hydrogen bonds among water molecules supply water the ability to hold heat better than many other materials. because the temperature rises, the hydrogen bonds among water always break and reform, allowing for the general temperature to remain stable, although improved strength is introduced to the device.

The organelle here is lysosome as it collects the trash of the cell. The correct option is B.
What is a lysosome?A lysosome is a cell organelle that contains digestive enzymes and is membrane-bound.
Lysosomes are involved in a variety of cellular processes. They degrade extraneous or worn-out cell parts. They could be used to eliminate invading viruses and bacteria.
Lysosomes serve as the cell's digestive system, degrading material taken in from outside the cell as well as digesting obsolete components of the cell itself.
The lysosome's interior is acidic and contains numerous enzymes that break down molecules.
It is known as the cell's recycling center, but this does not imply that it only plays a passive role in the cell.
