ENG: do hormones act only on cells or can they act on other structures?
Answers
Answer:
Hormones act only on cells not structures.
Explanation:
Hormones act only on cells and they do not act on other structures because there are specific cells have receptors for that particular hormone. Some hormones bind itself to the receptors on the surface of target cells whereas other hormones enter the cells and bind itself to the receptors present in the cytoplasm or nucleus of the cell.

i. Identify an environmental problem associated with large-scale intensive agriculture on soil.
Answers
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.

- The virus releases its RNA genome into the cell.
- The virus’s RNA is translated into proteins by the cell’s ribosomes.
- Viral RNA polymerase helps transcribe more copies of the virus’s RNA.
- New viruses travel to the cell membrane of the infected cell and are released outside the cell.
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.

facts about nitrogen
Answers
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.

Answers
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.
What can you tell about bacteria that have been Gram stained?
A) Microscopic morphology
B) Macroscopic morphology
C) Gram reaction
D) A and C
Answers
Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.
How can mutations be harmful?
Answers
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.

Consider a cross between a plant with two flower colors, yellow and red. Yellow (Y) exhibits complete dominance over red (y). It also has either single blossoms or double blossoms, single blossoms (S) exhibit complete dominance over double blossoms (s). A dihybrid yellow, single blossomed flower is crossed with a red flowered and double blossomed plant. You observe the following phenotype frequencies among the 1545 offspring plants:
500 yellow flowers and single blossom plants
515 red flowers and double blossom plants
260 yellow flowers and double blossom plants 270 red flower and single blossom plants.
What is the recombination frequency between these two genes?
a. (260+270) 1545
b. 270/1545
c. 1545/ (260+270)
d. 260/1545
e. (500+515)/1545
f. 1545/260
g. 1545/270
From these results one can conclude that:_______.
a. the two genes are linked
b. the two genes are not linked
c. if the genes are linked, they are separated far enough apart to appear to assort independently
Answers
Answer:
1) option a is correct. (260+270)/1545
(Note about this option: In the statement, it is written as (260+270) 1545. Lacks the division symbol, / )
2) From these results one can conclude that the two genes are linked (option a)
Explanation:
To know if two genes are linked, we must observe the progeny distribution. If heterozygous individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1. If we observe a different distribution, phenotypes appearing in different proportions, we can assume linked genes in the double heterozygote parent.
We might verify which are the recombinant gametes produced by the di-hybrid, and we will be able to recognize them by looking at the phenotypes with lower frequencies in the progeny. Phenotypes with the highest frequencies represent the parental gametes.
To calculate the recombination frequency, we will use the following formula: P = Recombinant number / Total of individuals.
In the present example:
Parental) YySs x yyss
Gametes) YS parental type ys, ys, ys, ys
ys parental type
Ys recombinant type
yS recombinante type
The total number of individuals in the offspring: 1545
Phenotypic class Number of offspring
500 Y-S- (parental)515 yyss (parental)260 Y-ss (recombinant)270 yyS- (recombinant)According to this information, the phenotypic frequencies of the progeny differ from the phenotypic ratio 1:1:1:1. We can assume then, that these genes are linked.
The recombination frequency is:
P = Recombinant number / Total of individuals
P = 260 + 270 / 1545
P = 530/1545
P = 0.343
The genetic distance between genes is 0.343 x 100= 34.4 MU.
