Answer:

1. While Biology is the study of living things, living things themselves are made up of chemical composition. Our survival is dependant on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.

2. 170 pm is the radius of a Carbon Atom.

3. The vast majority of the mass of an atom is concentrated in its nucleus

4. Protons are found in the nucleus of the atom. This is a tiny, dense region at the center of the atom. Protons have a positive electrical charge of one (+1) and a mass of 1 atomic mass unit (amu), which is about 1.67×10−27 kilograms.

5. Neutrons are located with protons in the nucleus; they too exchange mesons with protons and with each other to form the strong nuclear force, but they do not have to overcome the repulsion from Coulomb forces since neutrons are not charged.

Answer:

sodium has 11 protons and 11 electrons.

Explanation:

There are 2 electrons on the first energy level, 8 electrons on the second level, and 1 electron on the third energy level.

Answer:

Strongest acid is hydrochloric acid

Weakest acid is rainwater

Strongest base is sodium hydroxide

Explanation:

pH is defined as the measure of hydrogen ion concentration in a particular solution. pH values seen between 0 and 1 are actually known to be strongest acids. Weakest acids are the ones that move towards neutrality. The neutral pH value is 7.0.

Looking at their pH values, we will discover that hydrochloric acid is the strongest acid. Rainwater is weakest acid because it moves towards neutrality. Sodium hydroxide is the strongest base.

In pH, values between 0-6 are referred to being acidic, 7 is neutral and while 8-14 are basic.

Here is some information you need to answer this question:

Cellular respiration equation:

C6H12O6+6O2 -> 6CO2+6H2O

Cellular respiration breaks the glucose (C6H12O6) molecules for energy and new molecules (CO2 and H2O are formed as byproduct).

Overall, there is a release in energy, but also more so of a net increase of energy.

Answer:

The double-stranded parent DNA molecule gets separated and provides two template DNA strands for daughter strands synthesis. Enzyme DNA polymerase adds nucleotides complementary to template strands and synthesize daughter strands.

Explanation:

Answer:

The a cell divides, it is important that each daughter cell receives an identical copy of the DNA. This is accomplished by the process of DNA replication. The replication of DNA occurs during the synthesis phase, or S phase, of the cell cycle, before the cell enters mitosis or meiosis.

Explanation:

Answer:

Mendel's law of dominance states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. ... The recessive allele will remain “latent,” but will be transmitted to offspring by the same manner in which the dominant allele is transmitted.

What is the law of segregation- The law of segregation ensures that a parent, with two copies of each gene, can pass on either allele. Both alleles will have the same chance of ending up in a zygote. In sexually reproducing organsisms, the genome is carried in two identical copies. A copy was inherited from each parent, in the form of a gamete

Answer:

Hurricanes are large, swirling storms. They produce winds of 119 kilometers per hour (74 mph) or higher. That's faster than a cheetah, the fastest animal on land. Winds from a hurricane can damage buildings and trees.

tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.

Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.

A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.

Wildfires are fires that burn out of control in a natural area, like a forest, grassland, or prairie. They often begin unnoticed. They spread quickly, and can damage natural resources, destroy homes, and threaten the safety of the public and firefighters. Humans cause most wildfires.

Hurricanes: Hurricanes form when warm air over the water rises, it is replaced with cool air, if there is enough warm water storm clouds and wind speed can grow and cause the hurricane.

Tornadoes: Tornadoes form when warm air collides with cold air.

Earthquakes: a sudden and violent shaking of the ground, sometimes causing great destruction, as a result of movements within the earth's crust or volcanic action.

Floods: an overflowing of a large amount of water beyond its normal confines, especially over what is normally dry land.

Wildfires: A wildfire, bushfire, wildland fire or rural fire is an unplanned, unwanted, uncontrolled fire in an area of combustible vegetation starting in rural areas and urban areas

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.

Answer: Waves are important for building up and breaking down shorelines. Waves transport sand onto and off of beaches, transport sand along beaches, carves structures along the shore. The largest waves form when the wind is very strong, blows steadily for a long time, and blows over a long distance.

The wind could be strong, but if it gusts for just a short time, large waves won’t form. Wave energy does the work of erosion at the shore. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out. The shallow part of the wave ‘feels’ the bottom first. This slows down the inshore part of the wave and makes the wave “bend.” This bending is called refraction.

Wave refraction either concentrates wave energy or disperses it. In quiet water areas, such as bays, wave energy is dispersed, so sand is deposited. Areas that stick out into the water are eroded by the strong wave energy that concentrates its power on the wave-cut cliff.

A wave-cut platform is the level area formed by wave erosion as the waves undercut a cliff. An arch is produced when waves erode through a cliff. When a sea arch collapses, the isolated towers of rocks that remain are known as sea stacks.

Wave Deposition

PictureRivers carry sediments from the land to the sea. If wave action is high, a delta will not form. Waves will spread the sediments along the coastline to create a beach. Waves also erode sediments from cliffs and shorelines and transport them onto beaches.Beaches can be made of mineral grains, like quartz, rock fragments, and also pieces of shell or coral. Waves continually move sand along the shore and move sand from the beaches on shore to bars of sand offshore as the seasons change. In the summer, waves have lower energy so they bring sand up onto the beach. In the winter, higher energy waves bring the sand back offshore.Some features form by wave-deposited sand. These features include barrier islands and spits. A spit is sand connected to land and extending into the water. A spit may hook to form a tombolo. Shores that are relatively flat and gently sloping may be lined with long narrow barrier islands. Most barrier islands are a few kilometers wide and tens of kilometers long.In its natural state, a barrier island acts as the first line of defense against storms such as hurricanes. When barrier islands are urbanized, hurricanes damage houses and businesses rather than vegetated sandy areas in which sand can move. A large hurricane brings massive problems to the urbanized

Answer:

Photosynthesis will be affected or may not occur.

Explanation:

This is because palisade mesophyll are packed cells and have cylindrical shape with chloroplasts. Chloroplast are present here which control chlorophyll and this area specialises in absorbing light energy from the sun efficiently. If it is below spongy mesophyll, it's ability to absorb light energy is affected as there is an hindrance layer, and when chlorophyll couldn't absorb light energy, photosynthesis cannot occur.
