Answer:
Cell membrane surround cells, but cell wall is an extra covering outside plant cells, made up of cellulose
A cell plasma membrane and cell wall surround the eukaryotic cell.In the animal cell, there is a plasma membrane. In the plant cell, both the plasma membrane and cell wall are present.
What is the plasma membrane?The plasma membrane is the outermost covering of the cell that restricts the movement of molecules across the cell. In eukaryotic cells, the plasma membrane is hydrophobic by nature. It has carriers and ion channels in it. The plasma membrane has proteins, glycolipids, glycoproteins, etc. Apart from this, the plasma membrane of animals has cholesterol.
The plant has a cell wall outside of the plasma membrane. The cell wall is made up of cellulose. The polysaccharide cellulose is composed of glucose monomers.The cell wall is more rigid than the plasma membrane. The cell wall is present in some bacteria and fungi, but the composition of the cell wall is different from that of the eukaryotic cell.
Hence, the cell is surrounded by the plasma membrane and cell wall in eukaryotes.

Which of the following items are pure elements-that is, made up of only one type of atom? Check all that apply.
-Iron
-Carbon
-Cheese
The items that are pure elements are Iron and Carbon
Pure elements are one that contains a single form of atom i.e., one kind of particle.
Iron (Fe) is a metal that belongs to pure elements as it has homogenous chemical composition. It cannot be broken by any chemical methods because it is the simplest form of the element. Similarly, Carbon (C) is also a pure element with homogenous chemical composition.
On the other hand, Cheese is a mixture. The basic ingredients used for the production of cheese are milk, salt, starter culture, and rennet. These result in cheese with constituents of milk, microorganisms and breakdown products of the reaction which contributes to the color and flavor of the product.
Therefore, Iron and Carbon are the pure elements

Using the diagram below, identify the ONLY portion of the nucleotide that is not the same in every piece of DNA. (phosphate, sugar, or base)
Answer:
Base
Explanation:
Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.
However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.
Note that, phosphate group and deoxyribose sugar are constant in every DNA.

Answer:
D. 3H2O
Explanation:
An atom is the smallest unit of matter that has the characteristics of a chemical element. It consists of protons, neutrons, and electrons - small electrically charged particles.
They make up molecules - electrically neutral groups of two or more atoms connected by chemical bonds. Multiple molecules that consist of two or more different atoms make up a chemical compound.
The chemical compound that has nine atoms is 3H2O. Here, we have three molecules of water. Each molecule consists of three atoms - two hydrogen atoms and one oxygen atom. This means that three of these molecules have a total of nine atoms.

For what length of time was the IT Support department able to close down each weekend during Richard's first month?
Nixon's concerns turned out to be valid. The unemployment rate reached a politically harmful 6 percent by the end of 1970.
In that year, Nixon named Arthur Burns as the head of the Federal Reserve. Burns rapidly established his independence by issuing Nixon a challenge: if Nixon failed to maintain federal spending under $200 billion, Burns would continue to keep the money supply constrained in an effort to combat inflation. Nixon complied with Burns' requests. He put off government employees' salary raises by six months in order to conserve money. One outcome was a nationwide postal employees' strike. Nixon employed the U.S. Army to keep the postal service operating, but in the end, he carved into postal workers' salary demands, erasing some of Burns' budget-balancing requirements.

What is the phenotypic ratio of the offspring when a man who has type A blood, and whose mother had type O blood, marries a woman who has type AB blood?
2 type A : 1 type AB : 1 type B
3 type A: 1 type B
1 type A : 1 type O
1AA :1AB : 1AO : 1BO
Answer:
The correct answer is - 2 type A : 1 type AB : 1 type B
Explanation:
The pattern of the inheritance in the ABO blood group system is the example of the multiple alleles and codominance. There are three alleles in this sytem that determines what blood group would be in an indvidual that are; IA, IB, and IO. The allele IO is a recessive allele to both IA, and IB alleles whereas IA and IB are show codominance when present in heterzygous condition.
Genotype of a person with “A” blood group can be IA IO or IA IA but as it is given that the mother of the male with A bglood group is O blood group which means there must be a IO allele would be present in the male too so the genotype would be IAIO.
The genotype of AB blood group mother would be IAIB as shows codominance. so the cross between these woulde be as follows:
IA IO x IA IB
Gametes :
IA IO , and IA IB
IA IO
IA IAIA IAIO
IB IAIB IBIO
phenotypic ratio = 2 A group : 1 AB group : 1 B group

Are basal taxon more likely to have derived or ancestoral characteristics? Why?
Cladograms show the evolutive relationship between different taxa, and the ancestral and derived characters in the order in which they emerged. Basal taxons are more likely to have ancestral characteristics.
What is a cladogram?A Cladogram is a graph drown as a tree, which is based on cladistic analysis. It represents the common ancestral relationships and the emergence of different characters among the involved groups.
This tree-type graph represents the relationship between the involved taxa according to a derived character and follows the maximum parsimony criterium.
A derived character is any trait that a group passes to its descendants. Through evolution, the characters change, and new changes are added.
When referring to a derived character, we mean that all the subsequent species in the cladogram carry the trait.
A cladogram provides an image of how new species keep characters that were inherited from older species.
Cladograms show the position of the recent groups concerning the most ancestral ones and where, through history, the derived characters emerged.
Basal taxons exhibit ancetral characteristics that emerged a long time ago.The most recent groups exhibit derived characters that emerged later in history.
Derived characters do not appear in ancestral groups.
The basal taxons are more likely to have ancestral characteristics, while the most recent taxons are expected to exhibit the derived ones.

Autopsy conducted on an individual who had died of pneumonia revealed bluish-green pus filling the lung. The causative agent of pneumonia was most likely to be
Proteus vulgaris
Escherichia coli
Salmonella typhi
Pseudomonas aeruginosa
Staphylococcus aureus
Answer:
The agent causing the pneumonia, where bluish-green pus was found, is most likely Pseudomonas aeruginosa.
Explanation:
Pseudomona aeuriginosa is a gram-negative bacteria that is one of the main causes of hospital-acquired infections, including pneumonias in mechanically ventilated patients.
One of the characteristics of P. aeuriginosa is the formation of a bluish-green pus, since it has the capacity to form cyanide-based blue pigment upon contact with the organic tissues it infects. This is the reason why previously P. aeruginosa was called a pyocyanic bacillus.
The other options are not correct because the only bacterium that produces blue-green pus is P. aeruginosa.
