If someone is riding on a train, the object will appear to be stationary from the train seat, such as a poster on the train, which is present in option B, and this example explains the nature of the motion.
What is the significance of the motion?When traveling by train, some substances appear to be moving along with the train, while others appear to be stationary. This is due to the relative nature of motion, and due to this person inside the train, objects outside the train are moving because the train is in motion, whereas objects inside the train are stationary.
Hence, if someone is riding on a train, the object will appear to be stationary from the train seat, such as a poster on the train, which is present in option B, and this example explains the nature of the motion.

What is homeostasis?The state of constant internal, physical, and chemical conditions maintained by living systems is known as homeostasis.
This is the state of the organism's optimal functioning, and it includes many different factors, such as core temperature and adequate fluid, being kept even within those pre-set limits.
Homeostasis is the state of balance within all physical systems required for a body to function properly and survive.
The nervous system and nucleus functions the same, as the nervous system makes control and co-ordination with whole body, nucleus also controls all cell's activities.
Digestive system works by breaking down the food and making it into its simplest form, just like that lysosomes also bears digestive enzymes.

why RNA chain is always transcribed on 3' to 5' template strand ?

Explanation:
RNA growth is always in the 5′ → 3′ direction: in other words, nucleotides are always added at a 3′ growing tip, . Because of the ANTIPARALLEL nature of the nucleotide pairing, the fact that RNA is synthesized 5′ → 3′ means that the template strand must be oriented 3′ → 5′.

Their genetic classifications are recorded. Do these data contradict the genetic model
Answers
Complete question:
The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.
Genotype Observed frequency
A → 18 individuals
B → 55 individuals
C → 27 individuals
Do these contradict the genetic model?
Use a 0.05 level of significance.
Determine the chi-square test statistic.
Answer:
Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.
Explanation:
Available data:
Crossed genotypes: twoGenotypes among the offspring; Three → A, B, and CExpected phenotypic ratio → 1:2:1Total number of individuals, N = 100A = 18 individualsB = 55 individualsC = 27 individualsSo, let us first state the hypothesis:
H₀= the population is equilibrium for this locus → F(A) = 25%, F(B) = 50%, F(C) = 25% H₁ = the population is not in equilibriumNow, let us calculate the number of expected individuals, according to their expected ratio.
4 -------------- 100% -------------100 individuals
1 --------------- 25% -------------X = 25 individuals A
2 -------------- 50% -------------X = 50 individuals B
1----------------- 25%--------------X = 25 individuals C
A B C
Observed 18 55 27 Expected 25 50 25 (Obs-Exp)²/Exp 1.96 0.5 0.16(Obs-Exp)²/Exp
A) (18 - 25)²/25 = 49/25 = 1.96
B) (55 - 50)² / 50 = 25/50 = 0.5
C) (27 - 25)²/25 = 4/25 = 0.16
Chi square = X² = Σ(Obs-Exp)²/Exp
∑ is the sum of the terms O are the Observed individuals: 2 in chamber B, and 18 in chamber A. E are the Expected individuals: 10 in each chamberX² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62
Freedom degrees = 2
Significance level, 5% = 0.05
Table value/Critical value = 5.99
X² < Critical value
2.62 < 5.99
These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.

The correct asnwer is d, basal nuclei.
Parkinson's disease occurs due to the lower level of dopamine in brain. It causes unnecessary tremors that originate especially from the region called thalamus. Therefore, thalamus is the correct answer.
In Parkinson's disease the tremors are different from any other kind of tremors, they are especially known as essential tremors. It is the disorder that causes the rhythmic contraction of muscles in an uncontrolled way, causing difficulty to the person in performing simple tasks.
There are some possibilities that can cause Parkinson's disease such as - Mercury poisoning, anxiety disorder, any kind of brain disease. Even though, there are evidence that 60 - 80% of cases are due to sudden reduction in the dopamine producing cells.
Parkinson's can be diagnosed by observing the person's symptoms. A neurologist can give the most correct diagnosis for Parkinson's. It has tremors in many places of the body, but most commonly affected areas are- hand and fingers, mouth or tongue, legs.

A hypotonic solution is one in which there is more water than solutes, such as when there are 10% solutes and 85% water. When there are more solutes than water, it is called a hypertonic solution, such as 40% water and 60% solutes, whereas in an isotonic solution, the concentration is the same.
What is the significance of the different solutes in the concentration?There are different solutions based upon the solutes and the solvent ratios, such as when the cell is placed in the hypertonic solutions, the cell removes water to the outside, and when placed in the isotonic solutions, the size of the cell remains the same.
Hence, a hypotonic solution is one in which there is more water than solutes, such as when there are 10% solutes and 85% water.

B. A helicase enzyme unwinds the DNA molecule, then corresponding nucleotides are added to the separated original strand forming two separate semiconservative molecules
Explanation:
DNA Replication is an important phenomenon as far as cell division is concerned. It is the process whereby a DNA molecule doubles its content or forms two DNA molecules from one.
In the semi-conservative model of DNA replication, an enzyme called DNA helicase unwinds the double stranded DNA molecule into two single strands. The single strands are then used as template for DNA polymerase to synthesize another molecule of DNA. Hence, two separate DNA molecules comprising of one old strand and one new strand.

Trade Winds is the name of the winds that blow from the Poles southward. So, the correct option is (A).
What are Winds?Wind is the movement of air caused by the uneven heating of the Earth by the Sun and the rotation of the Earth. This includes natural calamities/disasters ranging from light breeze to storms and tornadoes.
Sometimes winds arise from differences in atmospheric pressure. At the equator, the sun heats the water and land more than the rest of the world. Warm equatorial air rises up in the atmosphere and migrates towards the poles. This type of system is called a low pressure system while at the same time, cooler, denser air moves over Earth's surface toward the equator to replace the warmer air. This type of system is called a high pressure system.
The boundary between these two areas is called a front and the complex relationships between fronts cause different types of wind and weather patterns. The Earth contains five major wind zones:
