Answer:

Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. ... Millions of years ago, algae and plants lived in shallow seas

Answer:

The scheme most often used currently divides all living organisms into five kingdoms: Monera (bacteria), Protista, Fungi, Plantae, and Animalia. This coexisted with a scheme dividing life into two main divisions: the Prokaryotae (bacteria, etc.) and the Eukaryotae (animals, plants, fungi, and protists).

Answer:

this mutation leads to a constitutively active state where the receptor can not be inactivated by dephosphorylation  

Explanation:

Phosphorylation is a posttranslational modification that usually occurs at the side chains of serine, tyrosine and threonine residues, thereby regulating protein function. Phosphomimetic amino acids are substitutions (mutations) able to mimic the phosphorylated form of the protein, resulting in constitutive activation/inactivation of the corresponding protein. In this case, it is expected that the substitution of tyrosine to glutamate gives rise to a constitutively active state of the receptor by replacing tyrosine with a phosphomimetic residue.

Answer:

The outer core is liquid and the inner core is solid.

Explanation:

This statement is true, the inner core is not liquid it's solid.

The outer core is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.

Opportunity cost of the next best option forgone when one alternative is chosen over other alternatives. In order to determine the opportunity cost of making chairs, divide the number of tables made for each person by the number of chairs.

Mike's opportunity cost in making one chair = 4/20 = 1/5

Sandy's opportunity cost in making one chair = 6/18 = 1 / 3

Petrifcation can be defined as the process in which the organic material of the dead living being becomes fossil by the replacement of mineral deposition in the bony, hard material. Thus, although the body components gets decomposed wiped out due to this process. The body shape of the dead organism remains the same as that was in living.

Therefore, The is liquid and the inner core is solid. The opportunity cost of 1 chair is 1/5 table for Mike and 1/3 table for Sandy.

Answer: pH = 9.4

Explanation: in water, -log(molar concentration OH-) + -log(molar concentration H+) = 14

-log(H+) is pH

so pH = 14 - -log(OH-)

= 14 - -log(2.4*10^-5)

= 14 - 4.6

= 9.4

Answer:

Oxygen

Explanation:

-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.

-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

Answer:

Humans and many other animals have monogastric digestive systems with a single-chambered stomach. Birds have evolved a digestive system that includes a gizzard where the food is crushed into smaller pieces.

Explanation:

Answer:

The digestion process in Ruminants is completely different from humans.

This is because the digestion process in Ruminants begins by chewing and swallowing its food. The main diet for these animals includes grass, leaves and other parts of plants.

Answer:

any one got snap??

Explanation:

Answer:

lack of water and high concentration of heat and dryness

Explanation:

Deserts don't get that much rainfall, so desert wildlife are adapted to survive in such a dry climate. Take the camel, for instance, it can store three bathtubs of water in it's hump, so it can go a very long time without water. And without that rainfall, the desert is dry and, usually, very hot. Animals have adapted to this by only coming out in the nighttime when it's cooler.

Answer:

uncontrolled excessive growth of cells in the tissue

Explanation:

Contact inhibition is a cellular mechanism where cell growth is arrested when adjacent cells are in contact with each other. Contact inhibition serves to arrest further cell growth beyond a monolayer, by limiting the migration and/or proliferation of cells in a tissue or organ. In consequence, contact inhibition is critical for normal cells to stop proliferating. When contact inhibition is disrupted, cells undergo uncontrolled growth, which leads to the development of cancer and tumor progression.

Answer:

[tex]D_m=1/2[/tex]      

Explanation:

From the question we are told that

Assuming that questions a and be are solved

Diversity index D=2p_1p_2

with [tex]p_1 +p_2 =1[/tex]

Mathematically

[tex]D=2p_1(1-p_1)[/tex]

[tex]D=2(p_1-p_1^2)[/tex]

[tex]D=2({\frac{1}{4} -(p_1-1/2)^2}[/tex]

Therefore

Less distance may be traveled with grains whose sizes are greater and more erratic. This is because as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.

Both a reduction in particle size and rounding of initially angular pieces are effects of the protracted transport of material by water and wind current. The grains get smaller and more spherical the farther they have to travel.

Erosion, transport, and deposition all result in the formation of sedimentary rocks. A sediment's grain size provides crucial details on (1) the agent that caused the erosion/transport of the sediment and (2) the current's speed.

Therefore, as a stream moves downstream, its velocity progressively diminishes, causing the big and irregular grains to settle the first, hence option 3 is correct.
