Which two body systems interact to expel the waste product carbon dioxide

Biology
1 answer:
Pani-rosa [81]3 years ago
7 0

Answer:

excretory system  and circulatory system

Explanation:

Blood is  part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the  blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.

The catalytic efficiency of many enzymes depends on pH. Chymotrypsin shows a maximum value of kcat/KM at pH 8. Detailed analysis
kherson [118]

Answer:

The catalytic efficiency of the enzyme depends on several factors that can affect the activity of the enzymes. This factors include Temperature, pH, concentration of the substrate, concentration of enzyme and the presence of activators and inhibitors.

Explanation:

The catalytic efficiency of the enzyme depends on several factors that can affect the activity of the enzymes. This factors include Temperature, pH, concentration of the substrate, concentration of enzyme and the presence of activators and inhibitors.

For instance, the pH is an essential factor that has to be maintained properly for the appropriate catalysis by an enzyme. The most favorable pH of most of enzymes present from 6 to 8.

when foreign dna and plasmid are both cut with the same restriction enzyme and then mixed together, all molecules will form reco
Art [367]

False, Some plasmids may reanneal without taking in any more DNA. when plasmid and foreign DNA are combined after being cut with the same restriction enzyme

Enzymes that cleave DNA are known as restriction enzymes. Each enzyme distinguishes one or more target sequences and cleaves DNA at or close to those sequences.

Numerous restriction enzymes produce single-stranded DNA overhangs at the ends of their cuts, which are often staggered. But some result in blunt endings.

DNA ligase is an enzyme that joins DNA. A single, unbroken DNA molecule can be created by joining two sections of DNA that have matching ends using ligase.

DNA ligase and restriction enzymes are employed in DNA cloning to splice genes and other DNA fragments into plasmids.

An enzyme that cuts DNA and recognises particular DNA locations is known as a restriction enzyme. A number of restriction enzymes make staggered cuts at or near their recognition sites to create ends with a single-stranded overhang.

Answer:

Vimenin has no affect.

Cytochalasin interferes with actin filament formation;

Ccolchicine shows that microtubules are required to give a cell a polarity that the determines which end becomes the leading edge.

Explanation:

These observations suggest to me that

  • Vimenin has no affect.
  • Cytochalasin interferes with actin filament formation;
  • Colchicine shows that microtubules are required to give a cell a polarity that the determines which end becomes the leading edge.

Determine what kind of variation is related to the following trait: Pierced Ears.
uysha [10]

Answer:

D. Both Genetics and the Environment

Explanation:

Getting a pierced ear is both a genetic and environmental trait because, in males, it is not genetically transferred, rather it is a choice to manually pierce the ear maybe at birth, or much later in life. In females, however, pierced ears is a genetic trait because it is gotten naturally when they are born

These environmental factors include where a person stays, the kind of friends they keep, and people they try to imitate. Ear piercing is something that is done manually for males for various reasons.
