Answer:

The heat they lose is proportional to the surface area of their bodies, while the heat they produce is proportional to their mass. This means that larger warm-blooded animals can generate more heat than they lose and they can keep their body temperatures stable more easily.

Limang impormasyon tungkol sa mapa

Marat540 [252]

Answer:

Ang mapa ay ang paglalarawan ng kalawakan gamit ang mga simbulo at pinapahiwatig ang kaugnayan ng bawat bagay, rehiyon at tema ng nasasaad na kalawakan. Kadalasan ang mapa ay isang dalawang-dimensiyong modelo ng isang tatlong-dimensiyong kalawakan. Ngunit dahil sa mga kompyuter at mga kalipunan ng dato na siyang nagpalawig ng pagsulong ng Mga Sistema ng Heograpikong Impormasyon (Geographic Information Systems o GIS), nagagawa na ring nasa tunay na panahon at dinamiko o masigla ang paggalaw ng datos na heograpikal. Ito ay nakaguhit sa isang lapat na papel na may sukat na depende sa laki ng mapa. Ang mga elemento ng isang mapa ay ang mga sumusunod: iskala (scale), legend, pangalan ng lugar/mapa, direksiyon (north arrow), may akda ng mapa o kartograper, klase ng projection at petsa kung kailan ito ginawa at nilimbag.

Isang halimbawa ng mapa: ang mapa ng Pilipinas na nagpapakita ng mga rehiyon at mga lalawigan.

Mapa ng Mundo noong 1689.

Ang mapa ay ginagamit sa paglalahad ng anumang lokal na pag-aari ng buong mundo o parte nito. Puwede rin siyang gamitin upang ilahad ang anumang pamamagitan, tulad ng utak o kalawakan sa labas ng mundo. Ang mapa rin ay larawan ng isang lugar na nagpapakita ng direksiyon.

If two organisms are in the same phylum, which other classification category must they also share?

Nataliya [291]

The classification categories from most to least inclusive: kingdom, phylum, class, order, family, genus, species.

If two organisms are in the same phylum, they must also be in the same kingdom, as a phylum is a part of a kingdom. They can be in different classes and/or orders.

Answer:

Every object has a total energy which is the sum of its kinetic and potential energy:

E = Ek + Ep

Kinetic energy is, as the name suggests, the energy of moving. It is given through the equation:

Ek = m • v^2 / 2

From here, we can see that Ek depends on the object's velocity; if v=0, then Ek will also be zero.

Potential energy is the energy an object has on a certain height:

Ep = m • g • h

Obviously, if the height is zero, then the Ep=0 too.

Another important thing to note is that E is always constant; if Ek increases (or decreases), Ep will decrease (or increase) so that their sum will always be a constant value.

If the bowling ball sits at the top of the 40 meters tall building, it has no velocity, it doesn't move, but it is located on a certain height.

That means that, at the top of the building, the bowling ball has no kinetic energy:

E = Ep + Ek

- no velocity ---> Ek =0

E = Ep = mgh

Ep = 2 kg • 9.81 m/s^2 • 40 m

E = Ep = approximately 785 J

To conclude, at the top of the building Ep > Ek.

Now, the ball is falling, and it's halfway down and it's travelling 19.8 m/s. Now, its kinetic energy is:

Ek = m • v^2 / 2

Ek = 2 • 19.8^2 / 2

Ek = approximately 392 J

Now, since the ball is halfway down, that means that its height is 20 meters. So, its Ep is:

Ep = mgh

Ep = 2•9.81•20

We already stated that total energy is constant and that is the sum of Ep and Ek and that it is around 785 J. We could also find Ep:

Ep = E - Ek

Ep = 785 - 392

Whichever way we use to calculate, we'll get the value of approximately 392 J.

That means that, halfway down, Ep=Ek.

Since the ball is halfway down, that means that its Ep is half the value it was while at the top of the building. The other half is used on the ball's velocity producing kinetic energy. That's why these two are equal at the halfway down.

Just before it hits the ground, the bowling ball has no height, meaning it has no potential energy. That also means that its total energy is equal to its kinetic energy:

E = Ep + Ek

Ep = 0

E = Ek

We already said that the ball's total energy was around 785J, so its kinetic energy just before it hits the ground will be that exact value.

The lysosome is an organelle that is important to cellular homeostasis through its degradation of different compounds. Degradati

DiKsa [7]

Answer:

The presence of proton pumps in the lysosome membrane that allows the organelle to maintain higher concentrations of protons.

Explanation:

Lysosomes are known as a membrane-bound cell organelle that is present in many animal cells. They are spherical type vesicles in structure. Lysosomes contain hydrolytic enzymes these enzymes help in the break down of different kinds of biomolecules.

The lysosomal membrane helps to protect the cytosol, and rest of the cells, from the degradative enzymes which are present in the lysosome. They have the ability to maintains their pH by pumping in H+ ions (protons) from the cytosol across the membrane with the help of chloride ion channels and proton pumps.
