Answer:

Plant-eating animals are called PRIMARY CONSUMERS.

Explanation:

In an ecosystem, consumers are heterotrophic organisms that can not make their own food. They rather depend on producers or other consumers for food and nutrition. The organisms that derive their nutrition directly from plants are called primary consumers. They are also called herbivores as they feed on plant and plant products. For example, deer graze grasses. This makes deer a primary consumer and a herbivore.

What is the volume of 0.25 mol of ammonia gas at 1.00 atm and 273 K? (R= 0.0821 Latm/molK)What is the volume of 0.25 mol of ammo
ICE Princess25 [194]

Answer:

5.6L

Explanation:

Given parameters:

number of moles  = 0.25mol

pressure on gas  = 1atm

temperature  = 273K

Gas constant R = 0.0821Latm/molK

Unknown:

Volume of gas  = ?

Solution:

Using the ideal gas equation, we can solve this problem. The equation is a combination of the three gas laws: Boyle's law, Charles's law and Avogadro's law.

It is mathematically expressed as;

             PV = nRT

where P is the pressure

           V is the volume

          R is the gas constant

          T is the temperature

          n is the number of moles

All the parameters are in the appropriate units and we simply solve for the volume of the gas;

                1 x V = 0.25 x 0.0821 x 273

                      V  = 5.6L

Why are lethal dominant alleles so much more rare than lethal recessive alleles?
juin [17]

Lethal alleles cause the death of an organism prenatal or after the birth. Lethal alleles are usually a consequence of a mutation and they can be recessive, dominant or conditional. Since the lethal dominant alleles are harmful whether they are carried in homozygous (e.g.AA) or heterozygous (e.g.Aa) form,  a strong selection against them is present and thus these alleles are much more rare.

AKA. RADIOMETRIC DATING

We can learn about the past by studying the present.

The Principle of Uniformitarianism states that current geological processes are the same processes that were at work in the past. This principle was proposed by Charles Lyell in the 1800's

Absolute Dating

Involves finding the absolute age (actual age) of a rock or fossil.

Elements that emit particles and energy are radioactive.

As radioactive elements emit particles and energy, they form new isotopes or elements.

Is Water Wet? If So, What makes it wet, if not what makes it dry?
Monica [59]

Answer:

Water is a liquid. Water is not wet BECAUSE something is only wet when water is on that object.

Explanation:

For example, there is water is a glass cup, and then the glass cup spills onto the table, causing the table to be wet, BUT you can remove that water from the table with some paper towels or a rag. Therefore, the table is no longer wet. Or when you're out in the rain and it gets on your clothes and/or hair, then your clothes and/or hair is WET.

When you put water onto water, it's an addition of water, you don't say it's wet or wetter.

Now, let me further prove my point with a different element: Fire. Fire burns things, right? So, when fire is on an object, then that object is burned. And when you add fire to fire, it causes more fire; fire does not burn itself.

Therefore, water is NOT wet. Wet is an adjective to describe an object that has been touched by a liquid, in this case, water.

So, yeah, enjoy the rest of your day. I'm sure some would like to argue my point. Go ahead.
