What is DNA?
DNA is a hereditary material which is present in human beings as well as all other living organisms. Every cell which is present in an organism's body has DNA which is the same. Most of the DNA is situated in the cell's nucleus and small amount of it can be found in the cell's mitochondria as well.
Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.
DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule and a phosphate group. A base, phosphate sugar are together called as nucleotides.

In order to make 4 cups of tea, 1.00 kg of water is heated from 22.0 oC to 99.0 oC. How much energy is required? 1) One point for how you would set up the problem and correct answer 2) 1 point for explaining any conversions 3) One point for explaining if this is endothermic or exothermic and why
Answer:
[tex]322014\ \text{J}[/tex]
Explanation:
m = Mass of water = 1 kg
c = Specific heat of water = [tex]4182\ \text{J/kg}^{\circ}\text{C}[/tex]
[tex]\Delta T[/tex] = Change in temperature = [tex](99-22)^{\circ}\text{C}[/tex]
Heat or energy required in the system is
[tex]Q=mc\Delta T\\\Rightarrow Q=1\times 4182\times (99-22)\\\Rightarrow Q=322014\ \text{J}[/tex]
The energy required is [tex]322014\ \text{J}[/tex]
Unit of energy is Joule
[tex]mc\Delta T=\text{kg}\times \dfrac{\text{J}}{\text{kg}^{\circ}\text{C}}\times\ ^{\circ}\text{C}=\text{J}[/tex]
As heat is being absorbed by the water it is endothermic in nature.
Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body.
Sickle cell disease is caused by an abnormal type of red blood cell gene inherited by the parents. What is the name for different forms of the same gene?

I NEED HELP THIS DUE I 2 HOURS
There are two kinds of motion that earth possess, one is rotation and other is revolution. Therefore, earth does not stay in one place throughout the year. The earth revolves and spins around the sun. The Earth is situated between Venus and Mars.
What is rotation?The motion of the earth around its axis is known as rotation. Revolution refers to the motion of the earth about the sun in a fixed route or orbit. The earth's axis, which is an invisible line, forms a 6612° angle with its planet's orbit.
No, the earth does not remain stationary throughout the year. The Earth revolves around the sun. The earth revolves and spins around the sun. The Earth is situated between Venus and Mars, therefore it is neither too hot nor too cold.

D.
The relative age of fossils cannot be determined from their
position in sedimentary layers.
Answer:
The answer is B!
Explanation:
if they are lower this means that they have been on the ground longer there for older
The statement that is true about fossils is that fossils found in lower layers of sedimentary rock are older than fossils found in upper layers of sedimentary rock.
What are sedimentary rocks?
They are the types of rocks which are formed as a result of accumulation of minerals or organic particles at the surface of the earth.Sedimentation is the name given to a collective process which cause the particles to settle.
The study of sedimentary rocks is useful in civil engineering and as important sources of coal, fossil fuels and ores.The color of sedimentary rock is often determined by iron content and sometimes due to the presence of organic matter.
They are classified based on origin in to 4 types which are clastic, biochemical ,chemical and other sedimentary rocks.While based on composition they are classified as siliciclastic,carbonate ,evaporite,organic rich,siliceous ,iron-rich and phosphatic sedimentary rocks.

Solutions of lead(ii) nitrate and potassium iodide were combined in a test tube. write a formula equation for the reaction.
Answer: yellow
When you mix solutions of lead (II) nitrate and potassium iodide. The precipitate is yellow in colour and the compound is lead (II) Iodide. Pb (NO3)2(aq) + 2KI(aq) → PbI2(s) + 2KNO3(aq). Yes, it is a double displacement reaction.
Explanation: The lead nitrate solution contains particles (ions) of lead, and the potassium iodide solution contains particles of iodide. When the solutions mix, the lead particles and iodide particles combine and create two new compounds, a yellow solid called lead iodide and a white solid called potassium nitrate. When a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube, the precipitation of a yellowish solid is observed. This yellowish solid is lead iodide. Potassium nitrate is formed along with lead iodide. When lead nitrate is mix with potassium iodine, a precipitation reaction occurs and yellow precipitate of lead iodide is formed.

Solutions of lead(II) nitrate and potassium iodide were combined in a test tube.
Write a net ionic equation for the reaction between lead(II) nitrate and
potassium iodide.
Answer:
Explanation: When solutions of potassium iodide and lead nitrate are combined?
The lead nitrate solution contains particles (ions) of lead, and the potassium iodide solution contains particles of iodide. When the solutions mix, the lead particles and iodide particles combine and create two new compounds, a yellow solid called lead iodide and a white solid called potassium nitrate. Chemical Equation Balancer Pb(NO3)2 + KI = KNO3 + PbI2. Potassium iodide and lead(II) nitrate are combined and undergo a double replacement reaction. Potassium iodide reacts with lead(II) nitrate and produces lead(II) iodide and potassium nitrate. Potassium nitrate is water soluble. The reaction is an example of a metathesis reaction, which involves the exchange of ions between the Pb(NO3)2 and KI. The Pb+2 ends up going after the I- resulting in the formation of PbI2, and the K+ ends up combining with the NO3- forming KNO3. NO3- All nitrates are soluble. ... (Many acid phosphates are soluble.)
The net ionic equation for the reaction that occurs when solutions of lead(II) nitrate and potassium iodide are combined in a test tube is:
Pb²⁺(aq) + 2 I⁻(aq) ⇒ PbI₂(s)
Solutions of lead(II) nitrate and potassium iodide were combined in a test tube. This is a double displacement reaction. The complete ionic equation is:
Pb²⁺(aq) + 2 NO₃⁻(aq) + 2 K⁺(aq) + 2 I⁻(aq) ⇒ 2 K⁺(aq) + 2 NO₃⁻(aq) + PbI₂(s)
Spectator ions are those that appear both in the reactants and in the products. They do not participate in the reaction, so they do not appear in the net ionic equation. The net ionic equation is:
Pb²⁺(aq) + 2 I⁻(aq) ⇒ PbI₂(s)

A piece of wood has a mass of 2.85 g; when placed in 20.0 mL of water, the water volume increased to 23.4 mL. What is the density of this piece of wood?
_______ Answer _______Units
Answer:
d = 0.84 g/cm³
Explanation:
Given data:
Mass of wood = 2.85 g
Volume of water = 20.0 mL
Volume of water + wood = 23.4 mL
Density of wood = ?
Solution:
Volume of wood = (Volume of water + wood ) - Volume of water
Volume of wood = 23.4 mL - 20.0 mL
Volume of wood = 3.4 mL
1 mL = 1 cm³
Density of wood:
d = m/v
d = 2.85 g / 3.4cm³
d = 0.84 g/cm³
