A student wonders whether removing the nucleus from a cell would result in a new prokaryotic cell. Why would this procedure fail to produce a prokaryotic cell?
Answer:
Removing the nucleus from the cell would not make it prokaryote because there are more characteristics that makes a cell prokaryote.
A eukaryotic cell has nucleus as well as membrane bound organelles found in the cytoplasm.
Even if the student will remove nucleus from the cell, the membrane bound cell organelles will remain in the cell.
Hence, only removing the nucleus from the cell would not make it a new prokaryotic cell.

What do chloroplasts look like under a microscope?
I depends, though “small greenish blob” would be a good description. The other answers contain great pictures of plant chloroplasts under a decent quality light microscope. However, plants (and algae) don’t all have the same size of chloroplasts and the chloroplasts can be very hard to see when they are small, not just because of size, be also because they appear less green (small size = less light absorption = less green in color).
If you use fluorescence microscopy, then the chloroplasts glow reddish-orange in color (very cool, especially when you have swimming algae).

What parts of a nucleotide make up the backbone of a nucleic acid?
Answer:
The correct answer would sugar and phosphate.
The nucleotide consists of three units; sugar (ribose in RNA and deoxyribose in DNA), a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, thymine, or uracil).
The sugar group of one nucleotide is attached to sugar of another nucleotide with the help of phosphodiester bond.
Thus, alternate sugar and phosphate groups form the backbone of nucleic acid from which nitrogenous bases stick out.
An archipelago is a large group of islands. question 1 options:
a. True
b. False
Answer:
The statement is true
Explanation:
A large group of islands which are scattered closely in the body of water is called archipelago. The water body is usually oceans but it can be river and lakes. Volcano eruption is one of the main causes of making most of the island in an archipelago and these islands are called oceanic islands.
One of the example of archipelago is Finland’s Archipelago Sea which has more than 50,000 islands although many of them are so small that they do not measure even one acre. Therefore the statement is true.
What is the function of the bulbospongiosus muscle in both male and female?
Cyclones are formed due to
mist and snow
clouds and fog
warming of oceans
underwater earthquakes
Answer:
Correct answer is warming of oceans
Explanation:
when hot moist air flows at the upper surface of the ocean it tries to move in upward direction due to which less amount of air is left at the surface of ocean and hence a lower air pressure is created in this area.
surrounding air which is at higher air pressure try to push the low pressure air which rises the temperature of low pressure air and again this air moves upward leaving behind less air at the surface of the ocean.
when this high temperature and moist air moves in the upward direction it temperature decreases due to which clouds are formed . This combination of clouds and wind continuously grows and started spinning. When this combination of wind and clouds spin fast, that time an eye is formed at the center. At this center very low air pressure is there and air with high pressure flows down into this center.
In this way cyclones are formed.

Disaccharides are best defined as what?
A)Molecules added to soft drinks and other foods that are not found in nature.
B)Carbohydrates made by combining two smaller monosaccharides, such as glucose + fructose.
C)Carbohydrates made by combining many smaller sugars, such as starch.
D)Proteins made by combining many amino acids in a chain.
carbohydrates have chemical bonds that are a good source of energy for living things. A monosaccharide is a carbohydrate made by plants when energy from the sun combines water and carbon dioxide.
how are two other types of carbohydrates formed? give examples of each type
The other two types of carbohydrates are Disaccharides: when two monosaccharides are joined together. Polysaccharide: when more than two monosaccharides are joined together.
What is a carbohydrate?Carbohydrates are biomolecules made up of carbon, hydrogen, and oxygen. They are of three types, monosaccharides, disaccharides, and polysaccharides.
Disaccharides when formed release water, an example is a maltose. An example of a polysaccharide is glycogen.
Thus, the two additional forms of carbohydrate are Disaccharides are constituted when two monosaccharides are combined. When more than two monosaccharides are combined, the result is a polysaccharide.

Germ cells are haploid but gametes are diploid.
a. True
b. False
While gametes are diploid, germ-line cells are haploid. In prophase, I, independent assortment takes place. Homologous chromosomes' non-sister chromatids. Two chromatids, one on each of two homologous chromosomes.
What results in formation of diploid gamete?A germ cell splits into two portions during meiosis (reduced division), which leads to the formation of four gametes.
A diploid (i.e., containing coupled chromosomes) zygote is created during fertilization by uniting the male and female gametes.
Mitosis makes diploid offspring cells that are indistinguishable to the parent cell. Meiosis I is where the majority of the variations between mitosis and meiosis occur.
The homologous chromosomal pairs connect and are bonded together by the synaptonemal complex during meiosis I.
Therefore, it is true that Germ cells are haploid, but gametes are diploid.

What will happen to a red blood cell (rbc), which has an internal ion content of about 0.9%, if it is placed into a beaker of pure water?
Final answer:
A red blood cell placed in pure water, which is a hypotonic solution, will undergo hemolysis due to water rushing in via osmosis, causing the cell to swell and potentially burst.
Explanation:
If a red blood cell (RBC), with an internal ion content of about 0.9%, is placed into a beaker of pure water, the environment around the cell is considered hypotonic. Due to the higher concentration of solutes inside the RBC compared to the pure water, water will rush into the cell, a process driven by osmosis. With a fixed surface area, the RBC membrane can only stretch so much before the RBC will swell and undergo hemolysis, which is when the cells swell up with water and eventually burst.
Most cells have mechanisms in place to prevent excessive water intake, but red blood cells lack these regulatory systems, making them ideal for osmolarity studies. In a hypertonic solution, water would leave the RBC, causing it to shrink or crenate. However, in an isotonic solution, the RBC would retain its normal shape, with equal water movement into and out of the cell. This dynamic is essential for maintaining cellular function and integrity in different environments.

What drives the process of plate tectonics?
unequal heat distribution
ocean currents
earthquakes
gravity
Answer:
unequal heat distribution is a correct option.
Explanation:
Thermal convection drives the process of plate tectonics.The heat from the Earth inner surface results in the unequal heat distribution and formation of hot magma, which causes the flow of cooler magma and movement of the plates.Thus the heat which is transferred from the mantle result in plates tectonicsThe main driving force behind the process of plate tectonics is the unequal heat distribution within the Earth's interior. This heat comes from various sources, including the residual heat from the planet's formation and the ongoing radioactive decay of elements in the Earth's core.
The correct option is A.
The heat generates convection currents in the underlying semi-fluid layer of the Earth's mantle called the asthenosphere. These convection currents cause the movement of tectonic plates, which are large, rigid pieces of the Earth's lithosphere that float on the semi-fluid asthenosphere.
As the hotter, less dense material rises and the cooler, denser material sinks within the mantle, it creates a cyclical pattern of upward movement and downward motion. This convective flow exerts forces on the tectonic plates, leading to their gradual motion.
While ocean currents and earthquakes are related to plate tectonics, they are not the primary driving forces. Ocean currents are driven by various factors, including wind patterns, temperature differences, and the rotation of the Earth.
Hence , A is the correct option

Jason adds the antibiotic penicillin to a bacterial culture. The bacteria develop genetic modifications in their genome, which gives them resistance to the antibiotic penicillin. What caused this genetic modification?
mutations to the DNA sequence
normal gene regulation
operon gene induction
RNA interference
Answer:
The correct answer is- mutation to the DNA sequence
Explanation:
A change in the DNA sequence by base-pair addition, deletion or substitution or by any other way bring mutation in the DNA. In bacteria, random mutation occurs in their DNA sequence which can change the codon sequence and results in coding for some enzymes or protein that deplete the effect of antibiotics on them which provide antibiotic resistance to the them.
So by doing mutation in their DNA sequence bacteria can gain antibiotic resistance or the bacteria which already have the appropriate mutation in their DNA will be selected by natural selection and other bacteria will die due to antibiotic effect.
Therefore genetic modification is caused by mutation in the genetic sequence.
