A salamander relies on hydrogen bonding to stick to various surfaces. therefore, a salamander would have the greatest difficulty

Talja [164]

The hydrocarbons' surface.

Because the covalent link that exists between hydrocarbon surfaces is different from the surfaces to which the salamander can cling, the salamander has difficulties adhering to these surfaces.

The hydrogen bond is the bond that exists between hydrogen and a bigger molecule like nitrogen or oxygen, whereas a covalent bond includes sharing electrons.

<h3>What Are Hydrocarbons and What Do They Do?</h3>

Crude oil, natural gas, and coal are all examples of hydrocarbons, which are organic compounds made of hydrogen and carbon. The world's primary energy source and a highly flammable substance, hydrocarbons. Petrol, jet fuel, propane, kerosene, and diesel are only a few of its uses.

A cellular enzyme is effectively deactivated by an increase in temperature of 10°C. Which is the most likely mechanism of deacti

Sauron [17]

Answer:

C. The enzyme changes shape and is no longer able to bind the substrate.

Explanation:

The change in heat changed the size of the enzyme. The enzyme changed size and shape which made it incapable of bonding with the substrate.

Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly

Ipatiy [6.2K]

Answer:

I haven't really learned about cell types but I did find this information

Explanation:

How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.

epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

Hope it at least helps a little :)

Determine whether each statement describes mitosis, melosis, or both mitosis and melosis.

Kruka [31]

Answer:

This question is incomplete as it lacks statements, the statements and the answers are as follows:

occurs in organisms that sexually reproduce - MEIOSIS

occurs during growth and development - MITOSIS

the DNA is replicated - MITOSIS AND MEIOSIS

occurs in all organisms - MITOSIS

the number of chromosomes remains the same - MITOSIS

the number of chromosomes reduces by half - MEIOSIS

Explanation:

Meiosis and mitosis are both types of cellular divisions that occur in living cells. Mitosis involves the formation of two (2) daughter cells that are genetically identical to the parent cell while meiosis involves the formation of four (4) daughter cells that are genetically different from the parent cell.

The following are characteristics of the two division processes based on this question:

MITOSIS:

- It occurs during growth and development of an organism.

- it involves DNA replication

- it occurs in all organisms since every living organism undergoes growth and development.

- the number of chromosomes after mitosis remains the same in the daughter cell i.e. 2n remains 2n

MEIOSIS:

- It occurs only in organisms that sexually reproduce.

- it also involves the replication of DNA

- The number of chromosomes in the daughter cells is reduced by half i.e. 2n to n.

What is the optimum pH for each enzyme

uysha [10]

It’s not the most visible by your picture. The correct answers are where the highest point of each line is because that is where the enzyme is working most efficiently.

Here are my answers but because of the unclear image , please check them with my explanation above:

Pepsin. = pH2
Salivary Enzyme = pH7
Trypsin = pH9
