Biology Laboratory Manual A/Laboratory Skills 49 which plant grew the tallest
Answers
There are two plants being compared in the graph, the graph B will grew the tallest by the end of third week as being shown in the daigram
In the graph, two variables i.e, Height (in cm) and weeks are being compared. Height is given on the vertical axis or Y -axis and number of weeks is given on the horizontal axis or the X-axis. Here the manipulated variable which is number of weeks is given on the X axis as mentioned in the question and the responding variable which is the height of the plant is given on the Y axis.
After two weeks, Plant A was 7 cm tall, and
It was 9 cm high after three weeks.
After two weeks, Plant B was also 7 cm tall.
It was 10 cm high after three weeks.
Plant A grew on the third week by 9 cm - 7 cm = 2 cm.
Plant A grew the most during the second week, according to (e).
Plant B had the smallest first-week growth (f).
Plants A and B were the same height at the conclusion of the second week.
From the end of the second week to the end of the third week, Plant B expanded by 10 cm- 7 cm, or 3 cm.
So the plant B grew the highest.

It is your first time eating at Subway in the Student Union. Shortly after eating a ham sub, you become very sick. You swear that you will never eat there again. A few weeks later, you enter your dorm, and your roommate offers you some ham and cheese crackers. You cringe at the smell of the ham. Identity the unconditioned stimulus (US), conditioned stimulus (CS), unconditioned response (UR) and conditioned response (UR)
Answers
This kind of a question is based on classical conditioning.
The unconditioned stimulus is the fact that you got sick after eating the food. This is something that is involuntary. It produces an automatic response.
The conditioned stimulus is the decision that you took. You made the decision that you won't be having the same food again based on the fact that you got sick by eating there. This is a conditioned stimulus.
Weeks later, you cringe at the smell of ham. This is an unconditioned response, because it is an automatic response or a response that occurs without thought when an unconditioned stimulus is present.
The fact that you don't eat the ham they offered based on the past experience is a learned response, which is again called a conditioned response.

The top three organelles are______, ______ and _______ because they do _____________, ___________ and ___________
Answers
In a cell there are mainly 6 organelles: nucleus, mitochondria, chloroplasts, golgi apparatus, endoplasmic reticulum and ribosomes.
Out of these the top 3 cell organelles are nucleus, mitochondria and golgi apparatus because they are the source of all other cell components and they have crucial functions:
Nucleus: The storage of the DNA or the inherited material of the cell is one of the nucleus' two main jobs. It is in charge of organizing a variety of crucial cellular processes, including protein synthesis, cell division, growth, and a number of other crucial operations.
Golgi apparatus: Proteins obtained from the ER are further processed and sorted in the Golgi apparatus, or Golgi complex, where they are eventually transported to lysosomes, the plasma membrane, or secretion. As was already mentioned, the Golgi also produces sphingomyelin and glycolipids.
Mitochondria: The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria.

1. Redi tested the hypothesis by conducting the meat-jar experiment.
2. His conclusion would be that maggots do not come from meat.
Testing hypothesesHypotheses are tentative statements that are yet to be tested whether they are true or not.
In science, hypotheses are tested using well-designed experiments.
The belief that living things can come from non-living objects is known as spontaneous generation. It was a widely held belief for a long time until experiments are performed to prove otherwise.
Francesco Redi was able to test the hypothesis by conducting the meat-jar experiment. Many believe that maggots spontaneously come from meats.
By observing flies laying eggs on the meat in the uncovered jar, the notion that meats spontaneously give rise to maggots was totally dispelled. The eggs hatch to give rise to maggots.
Redi's conclusion would be that flies give birth to maggots through their eggs. Meats do not spontaneously give rise to maggots.

Rank Smallest to biggest atom, molecule, proton, atomic nucleus, electron, neutron, cellular nucleus, cell
Answers
The correct order from smallest to biggest size is as follows:
electron < proton = neutron < atomic nucleus < atom < molecule < cellular nucleus < cell
Electrons are the smallest in size with a -1 charge orbiting around the nucleus of an atom which consist of protons and neutrons. Protons and neutrons are approximately similar in size and mass which is greater than that of an electron. Electrons, protons and neutrons are the three fundamental sub-atomic particles. Then comes atomic nucleus which is made up of protons and neutrons followed by an atom which is the most basic unit of matter. Molecules are made up of atoms. When at least two atoms are bound together by one or more chemical bonds, a molecule is formed. Macromolecules, or huge molecules that are created through polymerization like DNA, are a common type of biologically significant molecule. In cells, DNA is contained inside the nucleus. Organelles are collections of macromolecules seen in some cells that are encased in membranes like chloroplasts and mitochondria. Cell organelles along with the cell nucleus and cytoplasm make up a cell, which is the largest in size in the given example.
Thus, the correct order (from smallest to biggest size) is electron < proton = neutron < atomic nucleus < atom < molecule < cellular nucleus < cell

A diagram of the solar system shows the sun in the middle. Why does every other object orbit around the sun?
• The sun is smaller than other objects in the solar system.
O The sun is an average size for a star.
O The sun is so bright.
O The sun is the most massive object in the solar system.
Answers
Every other object revolves around the Sun because the Sun is the most massive object in the Solar System. Therefore, the correct option is D.
The Sun's powerful gravitational pull causes every other object in the Solar System to revolve around it. The force that controls how celestial bodies move through space is called gravity. All the planets, moons, asteroids and comets in the Solar System are under the strong gravitational pull of the Sun due to their enormous mass.
As a result these objects are constantly pulled towards the Sun, due to which they revolve around it. As we know, the Solar System was formed by the interaction of the gravitational force of the Sun and the forward motion of these bodies, which keeps them in stable orbits.
Therefore, the correct option is D.

Nerve cells can form many branches. How does this relate to their function?
A) they need a shape that allows them to hook onto structures
B) they need a large surface area
C) they form networks with other nerve cells
Answers
An electrically excitable cell known as a nerve cell uses synapses, which are specialized connections, to communicate with other cells. With the exception of sponges and placozoa, the neuron is the primary element of nervous tissue in all animals.
Plants and fungus are examples of non-animals that lack nerve cells. Dendrites are the many, brief branching found on nerve cells. Depending on the sort of cell it is affiliated with, dendrites may branch extensively. The axon of another nerve sends electrical signals to dendrites. The cell body or a portion of it is then where it accumulates before transmission. The quantity, branching, and placement of the dendrites or projections that make up a nerve cell, collectively known as arborization, determine the structure of the nerve cell. Their ability to communicate with their environment and other nerve cells or neurons, as well as their responsibilities in computation, are determined by this.

Answers
25% will have the dominant phenotype, and 75% will have the recessive phenotype.
When purebred or homozygous individuals that differ in a particular trait are mated, all offspring will be heterozygous for that trait. If the trait is inherited as dominant and recessive, all F1 offspring exhibit the same phenotype as the parent homozygous for the dominant trait. Monohybrid matings have a dominant to recessive phenotype ratio of 3:1.
In complete dominance, there is no phenotypic difference between AA and Aa individuals. In imperfect dominance, the phenotype of heterozygous individuals is clearly less intense than that of homozygous individuals for the dominant allele, such that the AA and Aa genotypes produce different phenotypes. A cross of two F1 hybrids that are heterozygous for a single trait that exhibits imperfect dominance.
