A 20 N unbalanced force cause an object to accelerate at 1.5 m/s. What is the mass of the object?

Answers

Answer:

I believe it’s 13.33 m

Explanation:

Because a = Fnet / m

So if you plug the numbers in it’s : 1.5 m/s = 20n / m

Then you’ll want to cross multiply which it’ll be : 20n = 1.5m

Then you want to get m alone so you’ll divide 1.5 to both sides and that’ll leave you to

13.33 = m

Coastal regions of continents tend to have ______ climates than inland regions due to the stabilizing effects of steady ocean temperatures.

A.hotter
B.milder
C.colder

Answers

Answer:

B.milder

Explanation:

Water has a higher heat capacity than soil and rock, so the ocean takes much longer to heat and

to cool than the land.

Coastal areas will generally have more moderate temperatures than inland areas because of the

heat capacity of the ocean.

Coastal regions of continents tend to have milder climates than inland regions due to the stabilizing effects of steady ocean temperatures. Thus option B is correct.

What Are the Different Climate Types?

Five most important climate types are Tropical, Dry, Temperate, Continental and Polar

Tropical climate include the hot and humid zone of climate where the average temperatures  of this zone is greater than 64°F and  59 inches of precipitation per year.

Dry climate refers to  the zones which are dry as in this zone moisture is rapidly evaporated from the air leads to little precipitation.

Temperate climate refers to the  zone with warm and humid summers with some mild thunderstorms and winters.

Continental type of climate shows warm to cool summers, very cold winters with some snowstorms, strong winds etc.

Polar climate zone refers extreme cold, even in summer, the temperatures below 50°F .

Why does the organism engage in dormancy, hibernation, or migration?

Answers

Answer For,

Why does the organism engage in dormancy, hibernation, or migration?

Explanation:

Dormancy is a period in an organism's life cycle when growth, development, and (in animals) physical activity are temporarily stopped. This minimizes metabolic activity and therefore helps an organism to conserve energy.

Hibernation is an adaptation that helps many animals conserve energy by remaining inactive, greatly slowing their metabolism and reducing their body temperature for days, weeks or even months at a time. Typically, animals hibernate in order to survive long periods when food is scarce.

Some animals travel relatively short distances to find food or more favorable living or breeding conditions. Most animals that migrate do so to find food or more livable conditions. Some animals migrate to breed. The Atlantic Salmon begins its life in a river and migrates downstream to the ocean.

Synthesize enzymes from organic molecules

The option (C) is correct. Synthesize enzymes from organic molecules.

What are enzymes?

Enzymes are proteins that act as biological catalysts by accelerating chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.

Moreover, enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.

Therefore, enzymes create chemical reactions in the body, and can actually speed up the rate of a chemical reaction to help support life. Enzymes are produced naturally in the body and help with important tasks, including: building muscle. destroying toxins.

list and describe three factors that affect how quickly enzymes can work to catalyze reactions

Answers

Answer:

The correct answer is - temperature, pH, substrate concentration.

Explanation:

Various factors affect the rate of enzymatic reaction such as pH, temperature, substrate concentration, availability of activators or inhibitors in the reactions, and enzyme concentration.

Temperature: Temperature affects the rate of the enzyme-catalyzed reactions. Like most of the reactions with an increase in temperature rate of enzymatic reaction also rises up to a maximum level and then declines if the temperature continues to increase as enzyme denatures after a particular temperature.

pH: Similar to the temperature pH also increases the rate of reaction up to a maximum level and then declines the rate as every enzyme acts only at an optimum pH range.

Substrate concentration: If the substrate concentration is increased gradually while the concentration enzyme remains constant, the rate of reaction will increase until it reaches a maximum.

Gene therapy can be defined as the methodologies used to modify/restore the expression of target genes and thus cure and treat genetic disorders. Gene therapy approaches consist of delivering specific nucleic acids (either RNA or DNA) in the cells of the individual to be treated. Some of the most important gene therapy approaches include the use of small interfering RNAs (siRNAs) in order to block target gene expression, adenovirus vectors to insert genes into host cells, the use of the CRISPR-Cas9 genome editing system to insert specific sequences by the mechanism of homologous recombination, etc.

What did you have to do to turn an atom that is labeled “+ion or -ion” into a “Neutral Atom”?

Answers

make sure the protons and electrons are eaual

To make any neutral atom, it should balance an equal number of electrons and protons, with +ion having more protons, and -ion having more number of electrons.

What is a neutral atom?

A neutral atom defines as an equal balance of electrons and protons, to make any atom into ions, it has to gain protons or electrons to make “+ion or -ion”.

All atoms are made of electron and proton in which their nucleus contains protons, a positive entity, and electrons, which surrounds the nucleus having a negative entity.

Ions are also a type of atom but have gain or loss of any number of electrons or protons. If any ion denotes +2 it shows having an extra number of protons.

Therefore, turning an atom that is labeled “+ion or -ion” into a “Neutral Atom” is done by adding or deleting the electrons.

Explanation:

Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.

D. A multipotent cell can become many different types of specialized cell within a tissue or organ, but it is more limited than a pluripotent cell.

Explanation:

Both pluripotent and multipotent cells are types of cells that can form multiple types of cells in the body. They are very similar, but there is one key difference. Multipotent cells are more limited than pluripotent cells. Pluripotent cells can form all cell types that make up the body. An example of pluripotent cells are embryotic cells. Multipotent cells are more limited, although they can develop into more than one cell type. Examples of types of cells that belong to this group are adult stem cells and cord blood stem cells.

Pluripotent and multipotent cells different such that multipotent cell can

become many different types of specialized cell within a tissue or organ, but

it is more limited than a pluripotent cell.
