In this picture the ground is now completely covered in vegetation and trees are growing back all along the road and sides of the picture. Then there’s little flowers and grass and bushed all over the place. In the other pictures the ground was bare, with the second and third pictures having bushes and other little vegetation starting to grow. Changes in the Biotic Factors: There are now larger trees, there is grass, flowers, small bushes, and other small vegetation growing. Changes in Abiotic Factors: The ground is no longer dust and ash, The dead trunks and branches are covered in vegetation for the most part and are decomposing.

Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other

Explanation:

Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.

Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.

Patterns are regular and intelligible forms , sequences, or structure that  found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.

For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.

Thus, it is clear from above explanation,  the ways to use patterns of classification in science.

Answer:

1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:

-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.

-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.

-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.  

-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.

2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.  

Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail  

This is us, we have thumbs, and vertebrates.

3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

Explanation:

Answer: It releases oxygen and heat. The answer is C

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen  you get a flame. Matter does not go when something is set on fire. Matter is always the same.  Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).

Answer:J

Explanation:Substitution

Mutation in genes can result in different types of abnormalities. In gene related to hemoglobin makes RBCs sticky, irregular shaped, this is because of substitution.

Mutation is a type of replication error during formation of new DNA.

In substitution mutation, incorrect nucleotide is placed at incorrect position during DNA replication, a point mutation occur in which a single nucleotide is substituted.

It actually does not add or remove any nucleotide from the sequence, just it substitute it.

In gene related to hemoglobin, the amino acid glutamic acid gets replaced with the valine amino acid at position 6 in beta-globin, which results in sticky, irregularly shaped red blood cells.

Thus the correct option is J.

Answer:

C. Aerobic respiration

Explanation:

Aerobic respiration occurs when oxygen is present

Anaerobic respiration occurs in the absence of oxygen. Anaerobic respiration is usually associated with fermentation process (eg Alchohol production)

The main difference between aerobic and anaerobic respiration is that aerobic respiration needs oxygen to occur, while anaerobic respiration does not. Option C. Only aerobic respiration requires oxygen.

Aerobic and anaerobic respiration occurrence depends on the presence or absence of oxygen. Option C. Only aerobic respiration requires oxygen.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

This type of respiration occurs in the presence of free oxygen. It involves a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

Aerobic Respiration occurs in mitochondria, and takes place in two steps or stages: Krebs cycle and electron transporter chain.

Glycolysis and Krebs cycle produce electrons. These electrons then travel along the electron transporter chain while releasing energy, and ATP is produced.

This is the type of respiration that occurs in the absence of free oxygen.

It is also a series of reactions by which the cell produces 2 ATP molecules by using pyruvate (product of glycolysis).

Anaerobic respiration can occur in two ways: lactic fermentation and alcoholic fermentation.

The whole anaerobic process occurs outside the mitochondria.

Options:

A). Only aerobic respiration involves fermentation. FALSE.

Anaerobic respiration involves fermentation.

B). Only anaerobic respiration occurs in the mitochondria. FALSE.

Aerobic respiration occcurs in mitochondria and anaerobic respiration occurs in the cytoplasm.

C). Only aerobic respiration requires oxygen. TRUE

Anaerobic respiration does not need oxygen.

D). Only anaerobic respiration produces carbon dioxide. FALSE

Alcoholic fermentation produces CO₂ too.

The correct option is C. Only aerobic respiration requires oxygen.

One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.

As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64  kJmol-1

Explanation:

ΔG°' for Citrate is +6.64 kJmol-1

ΔG°' for Isocitrate is -267 kJmol-1

ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant

ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)

Answer:

B. Speciation has occurred because breeding between the offspring and original populations would not be possible.

Explanation:

Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.
