Answer:
Two parts of a prokaryote that are also found in plant or animal cells are the cell wall and the ribosomes.
The word "Pneumococcus" tells you the shape of this bacteria. The word "coccus" is derived from the Greek word for "sphere" and it refers to the spherical shape of this bacteria. A common English word that would describe the shape of this bacteria would be "round".
Knowledge about cyanobacteria is important because they are the oldest known form of life on Earth, and they produce oxygen through photosynthesis, which is necessary for the survival of many other organisms. Additionally, cyanobacteria are an important source of biofuel.
Knowledge about bacteria such as salmonella or e-coli is important because these bacteria can cause food poisoning if consumed, and can also spread from person to person through physical contact or through contact with contaminated surfaces.
The process that allows bacteria to reproduce is called binary fission

The ability to form a covalent bond between its amino and carboxyl groups.
What is covalent bond?
A covalent bond is a type of chemical bonding that occurs between two non-metallic atoms. This type of bond is formed when the outer valence electrons of each atom are shared between the two atoms, resulting in the formation of a chemical bond. Covalent bonds are strong and can be found in a variety of molecules, including water and carbon dioxide. This type of bond is often found in many organic molecules, including proteins, carbohydrates, and DNA. Covalent bonds are important for the stability of many molecules and are responsible for the unique properties of many substances. Covalent bonds can be single, double, or even triple bonds depending on the number of electrons shared by each atom. In general, the strength of a covalent bond is determined by the number of electrons shared between the two atoms, as well as the distance between them.

Go back to the simulation and increase the number of molecules of heavy species to 700. What change do you observe?.
If you increase the number of molecules of heavy species to 700 the container expands/gets bigger when molecules are introduced. The molecules also exert pressure and move more slowly.
Why does the pressure change as the number of molecules increases?
The gas molecules' kinetic energy rises, increasing the force with which they collide with the container's walls. The outcome is a twofold increase in gas pressure.
Pressure rises when the number of gas molecules rises while the volume of the container stays the same. Gas pressure rises as container volume decreases. The pressure rises as the temperature of a gas inside a rigid container rises.

If there are 8 amino acids, how many bases were on the mRNA?
The number of bases on the mRNA depends on the specific sequence of the mRNA. However, in general, the genetic code is read in groups of three nucleotides (codons), where each codon corresponds to a specific amino acid. Therefore, for 8 amino acids, the minimum number of nucleotides (bases) required would be 24 (3 bases per codon x 8 codons).
What does the genetic code signify?The genetic code is a set of rules that determines how the information in DNA and RNA is translated into the amino acid sequence of proteins. Specifically, the genetic code defines the relationship between the sequence of nucleotides in DNA or RNA (called codons) and the sequence of amino acids in proteins. Each codon is a three-letter sequence of nucleotides, and there are 64 possible codons. Of these, 61 codons correspond to specific amino acids, while the remaining three codons are stop codons that signal the end of protein synthesis. The genetic code is universal, meaning that it is the same in all living organisms, and it is a fundamental aspect of the central dogma of molecular biology.

c) Ice floats in liquid water.
d) Salt-water freezes at a lower temperature than

e) Floating ice can insulate bodies of water.
Water has an unusually high specific heat. This mean 'a large amount of heat is required to raise the temperature of water'.
What exactly do you mean by temperature?
Temperature is a measure of the average kinetic energy of molecules in a sample of matter, expressed in terms of degrees on a specific temperature scale. Temperature can be measured using thermometers, which use materials that expand or contract in response to changes in temperature.
The high specific heat of water means that it has a high heat capacity. This means that it can absorb a lot of energy before its temperature increases. This is due to the strong hydrogen bonds between water molecules, which require a lot of energy to break. When energy is added to water, the hydrogen bonds absorb it and the temperature of the water rises slowly. This is why it takes a lot of energy to raise the temperature of water.
Hence, option B is correct.

Proteins serve many diverse functions. Some function as ____________ , catalyzing metabolic reactions within cells.
Enzymes. Proteins called enzymes catalyse biological reactions that otherwise would not occur.
Chemical reactions like digestion and cellular metabolism depend on these enzymes. Without enzymes, the majority of physiological processes would move so slowly—or even not at all—that life would be impossible. By aiding the molecular rearrangements necessary for cell activity, enzymes—protein catalysts—speed up biological reactions. Remember that chemical reactions change substrates into products, frequently by joining or separating chemical groups from the substrates. In your body, protein plays a variety of roles. It enables metabolic responses to happen, aids in tissue building and repair, and synchronises biological processes.

Compare transport across the plasma membrane and nuclear envelope: 1. Plasma membrane controls passage of charged substances but uncharged substances pass freely; nuclear envelope has pores that let small molecules through freely but controls passage of large molecules. 2. Plasma membrane controls passage of large molecules but small molecules pass freely; nuclear envelope has pores that let all molecules through freely. 3. Plasma membrane and nuclear envelope control passage of most substances. 4. Plasma membrane controls passage of most substances; nuclear envelope has pores that let small molecules through freely but controls passage of large molecules. 1 2 3 4
The correct answer is 4: Plasma membrane controls passage of most substances; nuclear envelope has pores that let small molecules through freely but controls passage of large molecules.
The plasma membrane and nuclear envelope are both selectively permeable barriers that control the passage of molecules into and out of the cell or nucleus, respectively. The plasma membrane controls the movement of most substances, including both charged and uncharged molecules, but allows small molecules to pass freely through its lipid bilayer while controlling the passage of larger molecules through specific transport mechanisms such as ion channels, transporters, and pumps. On the other hand, the nuclear envelope has small pores that allow small molecules such as ions, water, and gases to pass freely, but it controls the passage of larger molecules such as proteins and RNA through active transport mechanisms involving nuclear pore complexes. Therefore, option 4 accurately reflects the similarities and differences between transport across the plasma membrane and nuclear envelope.
