Explanation:
Coronaviruses are viruses from the family Coronaviridae (Order Nidovirales), which are structurally composed of positive-sense single-stranded RNA (ssRNA) genomes with a size of approximately 25 to 33 kilobases. Since the coronavirus genome consists of an ssRNA, they can be directly translated into protein inside infected host cells. The coronavirus that has caused the recent pandemic can enter into host cells through its spike (S) glycoprotein which binds to the Angiotensin-converting enzyme 2 (ACE2) receptor. Subsequently, this virus exploits the host molecular machinery to encode an RNA polymerase which is used to generate RNA from an RNA template. Finally, these RNAs are translated into all viral components (structural proteins) and new viruses are recruited to infected cells.

Put these statements in correct order to understand how hearing works. - Ions enter hair cells - Stapes moves - auditory cortex recognizes the sounds - hair cells bend - Incus moves - auditory nerve transmits the signal to the auditory cortex - Fluid wave moves across Organ of corti based on frequency - Sound wave enters inner ear - Fluid in the cochlea moves - sound wave is generated from hitting a key on a piano
Answer: From the question,the correct order of how hearing works is listed below:
--> sound wave is generated from hitting a key on a piano,
--> Incus moves,
--> Stapes moves,
--> Sound wave enters inner ear,
--> Fluid in the cochlea moves,
--> Fluid wave moves across Organ of corti based on frequency,
--> Ions enter hair cells,
--> hair cells bend,
--> auditory nerve transmits the signal to the auditory cortex,
--> auditory cortex recognizes the sounds.
Explanation:
In mammal, two ears are present on each side of the head. It is know as the organ for hearing and balance. The ear is divided into three regions:
--> OUTER EAR: This consists of pinna, ear canal, and eardrum( tympanic membrane)
--> MIDDLE EAR: This consists of the ear ossicles ( malleus, incus and stapes).
--> INNER EAR: This consists of Cochlea (organ of hearing) and semicircular canals (for balance).
To explain further on how we hear sounds, the vibrations of sounds produced from an external source move from the outer ear to the middle and then to the inner ear where the cochlea, the organ for hearing is located.
As sound wave is generated from hitting a key on a piano, the pinna collects the sound waves and directs them into the ear canal. Sound waves impinge on the tympanic membrane and makes it vibrate. This causes the malleus, incus and stapes (in this order) to move to-and -fro at the middle ear region.
In the inner ear region, sound wave enters inner ear as stapes pushes the oval window in-and-out. The vibrating oval window causes the fluid in the cochlea( perilymph) to move to-and -fro. Fluid wave moves across Organ of corti based on frequency. The pressure waves in the perilymph push the membrane separating the upper canal and the cochlear duct to-and-fro allowing ions to enter the hair cells. As a result, the hairs of the sensory cells between these two membranes bend causing nerve impulses to be sent to the brain through the cochlear part of the auditory nerve. Auditory nerve transmits the signal to the auditory cortex which recognizes the sounds.

a. This structure undergoes a series of distinct developmental stages regarding the cotyledons.
b. This is the mature dormant structure during unfavorable conditions.
c. This structure performs a nutritive function
d. This one structure contains the other two.
e. This is the first stage in the next sporophyte generation .
f. This structure is triploid following the process of double fertilization.

Seed Endosperm Embryo
Answer:
a. Embryo
b. Seed
c. Endosperm
d. Seed
e. Embryo
f. Endosperm
Contains a region called the hypocotyl: embryo
Explanation:
The seed is the first developmental stage in the sporophyte generation of the life cycle of angiosperm plants. This structure is composed of the endosperm, the embryo and the seed coat. The endosperm is a triploid (3n) tissue that nourishes the embryo during early growth. Moreover, the diploid (2n) embryo is the seed part that will become a seedling and eventually grow into a plant, with roots, stem, leaves and flowers. Finally, the hypocotyl is the small stem-like structure of a germinating seedling.

facts about nitrogen
Answer:
Nitrogen is the chemical element with the symbol N and atomic number 7. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. Although Carl Wilhelm Scheele and Henry Cavendish had independently done so at about the same time, Rutherford is generally accorded the credit because his work was published first. The name nitrogène was suggested by French chemist Jean-Antoine-Claude Chaptal in 1790 when it was found that nitrogen was present in nitric acid and nitrates. Antoine Lavoisier suggested instead the name azote, from the Greek"no life", as it is an asphyxiant gas; this name is instead used in many languages, such as French, Italian, Russian, Romanian, Portuguese and Turkish, and appears in the English names of some nitrogen compounds such as hydrazine, azides and azo compounds.

How can mutations be harmful?
Answer:
It can be harmful in many ways
Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.
Answer:
Mutations could be harmful if they change the codes for protein synthesis in such a way that a particular protein will not be able to conduct its routine function and will cause ailment. However not all mutations are harmful, there are very few number of mutations that actually can change the codes for a better functioning protein.

O
C. Multiply 500 by 1.5.
D. Divide 300 by 1.5.
Answer:
The correct answer is - C. Multiply 500 by 1.5.
Explanation:
Given:
Force to move a desk = 500 N
weight of desk = 300 N
displacement = 1.5 meters
work done by Tine = ?
Formula:
work done (W) = F*d
where F is the force applied on the desk and d is the displacement of the desk.
Solution:
As the displacement is perpendicular to the weight of the desk, therefore, the work done by weight is zero. The work done to the displacement of the desk would be =
W = F*d
= 500*1.5
= 750 J
Thus, the correct answer would be option C.

i. Identify an environmental problem associated with large-scale intensive agriculture on soil.
Intensive agriculture is resulting in the loss of ecosystem and is contributing to global warming.
• An agricultural mechanization and intensification system, whose main objective is to increase the productivity from the accessible land via several means like heavy use of chemical fertilizers and pesticides is known as intensive agriculture.
• The intensive agriculture is generally aimed to feed large population of humans, however, the method has contributed as one of the biggest threat to global environment, as it is resulting in the loss of ecosystem and global warming.
• It is accountable for the 80 percent of the tropical deforestation and emergence of novel parasites and reemergence of the parasites, which were under control at one time.
• The intensive farming hampers the beneficial plants and insects, and depletes and degrades the soil it relies upon.
• It is resulting in soil erosion and is resulting in the genetic erosion of the livestock species and crops around the globe.
Thus, intensive farming in order to feed large populations is eradicating the world agriculture slowly and gradually.
