Explanation:
For each - choose either peroxisome or lysosome, both or neither Group of answer choices uses hydrolases lysosome uses the enzyme catalase peroxisome is one of the main sites of fatty acid breakdown peroxisome combines with endosomes to digest ingested matter lysosome capable of converting hydrogen peroxide to water and oxygen peroxisome destroys engulfed bacteria both lysosome and peroxisome main role is metabolism both lysosome and peroxisome digestive interior is acidic lysosome proteins are derived from the endoplasmic reticulum
Answer:
Uses hydrolases -lysosome
Uses the enzyme catalase- peroxisome
Is one of the main sites of fatty acid breakdown- peroxisome
Combines with endosomes to digest ingested matter- lysosome
Capable of converting hydrogen peroxide to water and oxygen- peroxisome
Destroys engulfed bacteria- lysosome
Main role is metabolism- both lysosome and peroxisome
Digestive interior is acidic- lysosome
Proteins are derived from the endoplasmic reticulum- Peroxisome
Explanation:
The lysosome is a membrane-bound organelle found within a cell whose main function is to ensure the break down of biological polymers, such as proteins and polysaccharides. It is comprised of enzymes that are degradative in nature that can degrade biological polymers such as proteins, nucleic acids, lipids, etc. They contain various types of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatase. These enzymes are acid hydrolases as they function in the acidic environment of the lysosome. Lysosomes are also used by the cell to destroy invading viruses and bacteria.
Peroxisomes are membrane-bound organelles found within the cytoplasm of a cell. They are derived from the edoplasmic reticulum. Peroxisomes are involved in lipid biosynthesis, for example, cholesterol and dolichol are synthesized in peroxisomes. Peroxisomes are also involved in the synthesis of bile acids from cholesterol.
Peroxisomes contain enzymes that oxidize fatty acids and amino acids. Peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen preventing oxidative damage by these reactive oxygen species.

Homeostasis is the ability of the body to maintain internal balance despite changing external conditions. How does the respiratory system help maintain homeostasis? The respiratory system helps release hormones to control body processes. The respiratory system helps release unwanted heat and water from the body, The respiratory system produces white blood cells that kill disease causing organisms. The respiratory system releases enzymes that help in the break down of food.
Answer:
b on edge
Explanation:
its right
The respiratory system helps release unwanted heat and water from the body, maintaining homeostasis.
What is homeostasis?" A state of balance among all the body systems needed for the body to survive and function correctly."How respiratory system maintain homeostasis?Respiratory system helps to remove carbon dioxide and excess heat from our body and maintains our blood pH.During respiration, carbon dioxide reacts with water to form a carbonic acid in presence of enzyme carbonic anhydrase. It further dissociates into bicarbonate and H+ ions. This reaction are in equilibriumWhen the level of H+ ions increases, the pH level increases. This will signal respiratory system to release more carbon dioxide. This will result in formation of carbon dioxide and decrease level of H+ ions which will result in increase blood pH.When we breathe out, the moisture from the tissue are also expelled.Hence, the respiratory system helps release unwanted heat and water from the body.

O Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant
produced. THis is common in premature infants.
In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Respiratory distress syndrome (RDS) is a well-known breathing disorder that is common in premature infants. It happens when there is a lack of surfactant produced in the baby's lungs which is quite bad because surfactant enables babies to breathe when they are born by keeping the lungs expanded.
It is common in premature infants because the lungs only begin to produce surfactant in the third trimester so babies that are born prematurely did not get to produce sufficient quantities. If not treated immediately, brain damage could follow.

to differentiate between agarose gel electrophoresis and SDS-PAGE based on the following criteria:
2.2.1 Composition of gels
2.2.2 Dye used for staining
Explanation:
Agarose has a large pore size and is suitable for separating nucleic acids and large protein complexes. ... SDS-PAGE separates proteins primarily by mass because the ionic detergent SDS denatures and binds to proteins to make them uniformly negatively charged.
In this question we will differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.
Agarose gelThe gel matrix is created by dissolving a natural polysaccharide called dye-free agarose, which is derived from a type of seaweed, in a conductive buffer, in the approximate proportion of 1% to 3% agarose.
SDS-PAGEPolyacrylamide gel electrophoresis (PAGE) with sodium dodecyl sulfate (SDS). SDS-PAGE consists of a type of electrophoresis performed under denaturing conditions for the separation of proteins without dyes.
Whit this information, we can conclude that differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.

Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed size in the F1 progeny. She then backcrosses the F1 plants to one of the parental varieties and measures seed size in the backcross progeny. The grower finds that seed size in the backcross progeny has a higher variance that does seed size in the F1 progeny. Explain why the backcross progeny are more variable.
Answer:
The F1 progeny is completely heterozygous for the loci of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids
Explanation:
An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single locus, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing).
The primary source of the specificity of enzymes is ________. The primary source of the specificity of enzymes is ________. their polarity, which matches that of their specific substrate their shape, which relates to the lock-and-key model their bonded transition metal, which is specific to the target substrate their delocalized electron cloud their locations within the cell
Answer:
their shape, which relates to the lock-and-key model
Explanation:
Enzymes are biological catalysts that are proteinous in nature. Their proteinous nature implies that they are made of amino acids, which forms a three-dimensional shape that accounts for their functionality and specificity. This means that enzymes are substrate-specific because of their 3D shape.
The three-dimensional shape of an enzyme determines the kind of substrate it will bind to. Enzymes, generally, catalyze reactions by binding to a substrate at their active site. This binding follows a lock and key pattern or model. In a nutshell, the primary source of specificity of enzymes is attributed to their SHAPE, which relates to the lock-and-key model.

In healthy individuals, friction is a major factor affecting pulmonary ventilation
Answer: Infant Respiratory Distress Syndrome occurs when there is a lack of surfactant produced. This is common in premature infants.
Explanation:
Infant Respiratory Distress Syndrome (RDS) occurs in new born infants whose lungs are unable to produce the enough surfactant to keep their lungs expanded which would enable them to breathe properly after delivery.
It is most common in premature infants because surfactant is produced in the third trimester of pregnancy so premature infants might not get the chance to produce enough before the are delivered. RDS needs to be treated as soon as possible or else a baby could suffer damage to the brain and other vital organs.
