Why do lysosomes keep their digestive
enzymes in membranous sacs?
A. because the membranous sacs can sense when the cell is about
to be attacked
B. because the membranous sacs keep the digestive enzymes
from destroying the cell
C. because the membranous sacs act as tails that help the
lysosomes move faster
D. because the membranous sacs act as factories helping the
digestive enzymes make proteins
The correct answer is option B. because the membranous sacs keep the digestive enzymes from destroying the cell.
What is the purpose of the membrane surrounding the lysosome?The membrane surrounding the lysosome is vital to ensure these enzymes do not leak out into the cytoplasm and damage the cell from within. In order to maintain the acidic pH of the lysosome, protons are actively transported into the organelle across the lysosomal membrane.
What part of the cell is a membranous sac?
A vesicle is a small, membrane-bound sac that transports substances in cells. The ER moves proteins and other substances within eukaryotic cells. Vesicles that contain newly made proteins move through the cytoplasm from the ER to an organelle called the Golgi apparatus.

Which of the following is NOT a polymer?
Nucleotide
Polysaccharide
Triglyceride
Polypeptide
Answer:
Nucleotide ( monomer )
Explained Definition:
The classes of biological molecules may be grouped into the types of polymers they form and the monomers that act as subunits: Lipids - polymers called diglycerides, triglycerides; monomers are glycerol and fatty acids
1. The monomers of DNA are called nucleotides. Nucleotides have three components: a base, a sugar (deoxyribose) and a phosphate residue. The four bases are adenine (A), cytosine (C), guanine (G) and thymine (T). The sugar and phosphate create a backbone down either side of the double helix.
2. Polysaccharides, also called glycans, are large polymers composed of hundreds of monosaccharide monomers. Unlike mono- and disaccharides, polysaccharides are not sweet and, in general, they are not soluble in water. Like disaccharides, the monomeric units of polysaccharides are linked together by glyosidic bonds.
3. Fatty acids form more complex lipid polymers called triglycerides, triacyclglycerols or triacyl glycerides when each single-bonded oxygen molecule bonds to a carbon that's part of a glycerol molecule. ... Triglycerides are also commonly found in foods, especially animal products
4. polymers are known as polypeptides; monomers are amino acids. Nucleic Acids - polymers are DNA and RNA; monomers are nucleotides, which are in turn consist of a nitrogenous base, pentose sugar, and phosphate group

which molecule gets translated into a protein by the ribosome?
Answer:
Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
Explanation:
Molecule gets translated into a protein by the ribosome within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
What is RNA?Full form of RNA has ribonucleic acid and it has a nucleic acid which has been found in almost all cells that are living and RNA has mostly similar to DNA but there is one difference between RNA and DNA and the difference is that RNA has single stranded but DNA is double stranded.
The RNA has backbone has made up of the phosphate group which has arranged in alternating form and the sugar known as ribose other than the deoxyribose present in DNA. There are four bases found in RNA and these are adenine, uracil, guanine, and cytosine.
The main function of mRNA is it work as imedieter between protein and DNA which is utilised by ribosome for the process of direct synthesis of protein, and the function of tRNA is to carry the accurate amino acid to the proteins synthesis site which takes place in ribosome.
Therefore, Molecule gets translated into a protein by the ribosome within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis the stitching together of amino acids to make a protein molecule.

baby names connect to gender, and names flow from male to androgynous to female but never in reverse. the reason for this is that
In most cultural and religious doctrines, masculinity seems to be weighted well above the feminine gender. Hence, greater level of power or hierarchy is leveled towards the masculine gender. Hence, the reason for the trend in m naming pattern is due to the power alloted to male species.
Naming pattern usually follow the standard trend of having a root which is meant for the male kid, before transitioning to a fairly refined or similar name which is attributed to female kids. Intermediate names which can be used for either gender are called androgynous names sometimes precedes the female naming convention.Therefore, the pattern of naming with the masculine version coming first is due to the higher heirachical power given to males.

ou are designing a building that must minimize energy transfer in the form of heat loss. Describe a building shape that you think would minimize heat loss through the surface of the building, and explain how that shape relates to the surface area-to-volume ratio.
Answer: In principle, to minimise heat transfer through the building envelope the building shape should be as compact as possible,tending toward a cube.
Explanation:
A building's design should be compact and rounded to reduce heat loss through the surface. The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.
What should be the shape of building to minimize the heat?The optimum shape would be a sphere, but that is impractical for a building. It would be more practical to construct a building that is cylindrical or dome-shaped.
By lowering the building's surface area, this design limits the region where heat may escape from the structure. The surface area to volume ratio should be taken into account while trying to reduce heat loss.
A building that is compact and rounded, such a cylinder or dome, has a lower surface area-to-volume ratio than a building that is rectangular or square and has the same volume. Accordingly, less heat is lost from the building's surface in comparison to the heat that is kept inside the structure.
Additionally, a compact, rounded building will have fewer corners and edges, which are vulnerable to heat loss. Additionally, the structure can be angled to receive as much sun exposure as possible, which can add to the building's heating capacity during the winter.
Therefore, a building's design should be compact and rounded to reduce heat loss through the surface.
