Answer: The probability of an event is a number describing the chance that the event will happen. An event that is certain to happen has a probability of 1. An event that cannot possibly happen has a probability of zero. If there is a chance that an event will happen, then its probability is between zero and 1.
The number Which describes how likely it is that an event will occur is the probability of the event.
What is probability?The number describing a chance that an event will occur is called probability. It can be expressed in the form of numbers, from 0 and 1, or also by percentage from 0% to 100%. Higher probability of an event means that there are greater chances that event will occur.
Probability is branch of mathematics which is also applied in other fields such as, science, finance, statistics, gambling, computer science, machine learning, artificial intelligence and game theory.
Representation of probability in its formal terms, is called as probability theory. The probability theory is mostly used in risk assessment and modelling that is, it is used by insurance companies and markets.
Therefore, chances of number of event occur is called probability.

DNA contains the genetic code which is determined by what?
determines the amino acid sequence of proteins
A molecule that has regions of partial positive and partial negative charge
A) polar
B) hydrogen bond
C) surface tension
D) universal solvent
E) adhesion
Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".
Why do you think hemoglobin levels vary with altitude?
Answer:
haemoglobin in blood increases at high altitude. This is one of the best-known features of acclimatisation (acclimation) to high altitude. Increasing the amount of haemoglobin in the blood increases the amount of oxygen that can be carried.

Answer:
I hope this helps just to let you know this is what I searched just being honest :)
Explanation:
DNA
But your genes also mean that you probably look a bit like other members of your family. For example, have you been told that you have 'your mother's eyes' or 'your grandmother's nose'?
Genes influence what we look like on the outside and how we work on the inside. They contain the information our bodies need to make chemicals called proteins. Proteins form the structure of our bodies, as well playing an important role in the processes that keep us alive.
Genes are made of a chemical called DNA, which is short for 'deoxyribonucleic acid'. The DNA molecule is a double helix: that is, two long, thin strands twisted around each other like a spiral staircase.
27 DNA.gif
The DNA double helix showing base pairs
The sides are sugar and phosphate molecules. The rungs are pairs of chemicals called 'nitrogenous bases', or 'bases' for short.
There are four types of base: adenine (A), thymine (T), guanine (G) and cytosine (C). These bases link in a very specific way: A always pairs with T, and C always pairs with G.
The DNA molecule has two important properties.
It can make copies of itself. If you pull the two strands apart, each can be used to make the other one (and a new DNA molecule).
It can carry information. The order of the bases along a strand is a code - a code for making proteins.
Genes
A gene is a length of DNA that codes for a specific protein. So, for example, one gene will code for the protein insulin, which is important role in helping your body to control the amount of sugar in your blood.
Genes are the basic unit of genetics. Human beings have 20,000 to 25,000 genes. These genes account for only about 3 per cent of our DNA. The function of the remaining 97 per cent is still not clear, although scientists think it may have something to do with controlling the genes.
Chromosomes
If you took the DNA from all the cells in your body and lined it up, end to end, it would form a strand 6000 million miles long (but very, very thin)! To store this important material, DNA molecules are tightly packed around proteins called histones to make structures called chromosomes.
105-Gene-unwrapped.gif
The packaging of DNA into chromosomes
Human beings have 23 pairs of chromosomes in every cell, which makes 46 chromosomes in total. A photograph of a person's chromosomes, arranged according to size, is called a karyotype.
The sex chromosomes determine whether you are a boy (XY) or a girl (XX). The other chromosomes are called autosomes.
106-autosomes.gif
The karyotype of a male human being
The largest chromosome, chromosome 1, contains about 8000 genes. The smallest chromosome, chromosome 21, contains about 300 genes. (Chromosome 22 should be the smallest, but the scientists made a mistake when they first numbered them!).
The DNA that contains your genes is stored in your cells in a structure called the nucleus.

how far does a car travel in 0.75 h if it's moving at a constant speed of 88 km/h
Answer:
Distance = 66 kilometers
Explanation:
Given the following data;
Time = 0.75 hour
Speed = 88 km/h
To find the distance traveled by the car;
Distance = speed * time
Substituting into the equation, we have;
Distance = 88 * 0.75
Distance = 66 kilometers.
Therefore, the car will travel a distance of 88 kilometers.

In order for cellular respiration to effectively provide the energy your body needs to do its job, which of the following organ systems are needed?
(You may choose more than one answer.)
-Digestive system
-Respiratory system
-None of these systems support cellular respiration.
-Circulatory system
3.
The respiratory system supports the skeletal muscular system by:
-he respiratory system does not support the skeletal muscular system.
-transporting oxygen needed to release energy from glucose to the body's cells.
-breaking down the glucose to release energy.
-digesting the glucose you eat.
Answer:
1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers
1B - Skeletal = bones
1C - Muscular = muscles
1D - Digestive = stomach, large/small intestine
1E - Circulatory = heart, veins and arteries
2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive
3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.

Explain how thermohaline circulation is influenced by salinity and temperature.
Answer:
Thermohaline circulation is influenced by changes in density gradients. These density gradients are affected by the salinity and temperature of the ocean’s water. Cold water is denser than warm water and salt water is denser than freshwater. As water cools off, it sinks. As water evaporates, the salt concentration of the remaining water increases because the salt from the evaporated water remains. This causes the water to sink and circulate.
Explanation:
Changes in density gradients have an impact on thermohaline circulation. The salinity and temperature of the ocean's water have an impact on these density gradients.
What effect of thermohaline circulation?The distribution of heat to the polar regions is largely dependent on thermohaline circulation.
As a result, it impacts how quickly sea ice forms at the poles, which in turn affects other components of the climate system (such as the albedo, and thus solar heating, at high latitudes).
Both salt water and cold water are denser than warm or fresh water. Water sinks as it cools.
Because salt from the evaporated water persists, when water evaporates, the salt content of the remaining water rises. The water circulates and sinks as a result of this.
Therefore, thermohaline circulation is influenced by salinity and temperature.

Answer:
B
Explanation:
Igneous rocks are formed by the solidification of magma or lava.
Answer: Igneous rocks are made of B. materials that crystallized from magma or not lava, not from once living things
Explanation: Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material. Earth is composed predominantly of a large mass of igneous rock with a very thin veneer of weathered material—namely, sedimentary rock.
How is local weather influenced by global patterns of atmospheric movement?
Answer: A mountain range in the path of prevailing winds can influence where precipitation falls. When humid winds blow from the ocean toward coastal mountains, they are forced to rise. The rising air cools and its water vapor condenses, forming clouds.
