conditions, and resources
that a species needs in
order to survive and
reproduce
If niches overlap . . .
• Two or more species

2. Also submit a text-file, in which you explain in about one page what you have learned about the evolution of hominids. In the end, complete the following sentence: The notion that we evolved from modern apes (chimps) is clearly wrong. Rather, what we have evidence for is ....
The notion that we evolved from modern apes is wrong but we have evidence that humans evolved from apelike ancestors.
How did hominids evolve?With time, genetic change can change the overall way of life of a specie like eating behavior, growth, and place of living. Human evolution took place when new genetic changes occur in the ancestor's populations which favor new abilities in that organisms to adapt to environmental change. Scientific evidence indicates that the physical and behavioral traits that are shared by all people come from apelike ancestors which evolved about six million years. One of the earliest defining human traits is bipedalism i.e. the ability to walk on two legs was evolved over 4 million years ago.
So we can conclude that hominids evolved because of the genetic change that occurs with time due to environmental change. We have many evidence that humans evolved from apelike ancestors due to environmental change.

When someone is vitamin B12 deficient, one of the reasons could be that the person's dies does not contain proper amount of vitamin B12.
Is Vitamin B12 important?A crucial B vitamin is vitamin B12. It is essential for the health of the brain, the generation of red blood cells, and nerve tissue. Vitamin B12 can also be called as cobalamin.
When the body cannot absorb enough vitamin B12, a deficiency or an insufficiency can develop. If left untreated, this can cause a variety of symptoms, including the development of irreparable brain problems.
Like every other B vitamin, this vitamin B12 is a water-soluble vitamin. This implies that it can dissolve in liquid and circulate through the body.
Up to four years’ worth of vitamin B12 can be stored by the body, and any extra or undesired amounts can be excreted in the urine.

You have been given a stock glucose solution with a concentration of 100mg/mL. To perform the glucose assay in lab today, you must dilute the 100mg/mL stock solution of glucose to concentrations of 80mg/mL, 60mg/mL, 40mg/mL, and 20mg/mL. You need to prepare 1mL of each dilution. Explain how you would make the 4 dilutions from the glucose stock solution.
In order to prepare 1 mL 80 mg/mL, 1 mL 60 mg/mL, 1 mL 40 mg/mL, and 1 mL 20 mg/mL glucose solution from a 100 mg/mL stock solution, 0.8 mL, 0.6 mL, 0.4 mL, and 0.2 mL of the stock will be taking and diluted with 0.2 mL, 0.4 mL, 0.6 mL, and 0.8 mL water resectively.
DilutionThe dilution principle states that the number of moles of solute in the original stock before dilution must be equal to the number of moles of solute in the diluted stock.
This principle is mathematically expressed as: m1v1 = m2v2
Where: m1 and v1 = molarity and volume before dilution
m2 and v2 = molarity and volume after dilution.
In this case, the stock is 100 mg/ml.
To prepare 1 ml, 80 mg/mL solution: m1 = 100 mg/mL, v2 = 1 mL, and m2 = 80 mg/mL.v1 = v2m2/m1
= 1x80/100
= 0.8 mL
This means that 0.8 mL of the stock will be taken and diluted with 0.2 mL of water to make 1 mL, 80 mg/mL solution.
To prepare 60 mg/mL solution:v1 = 1 x 60/100
= 0.6 mL
This means that 0.6 mL of the stock will be taken and diluted with 0.4 mL of water to make 1 mL, 60 mg/mL solution.
To prepare 40 mg/mL solution:v1 = 1 x 40/100
= 0.4 mL
This means that 0.4 mL of the stock will be taken and diluted with 0.6 mL of water to make 1 mL, 40 mg/mL solution.
To prepare 20 mg/mL solution:v1 = 1 x 20/100
= 0.2 mL
This means that 0.2 mL of the stock will be taken and diluted with 0.8 mL of water to make 1 mL, 20 mg/mL solution.

what are the two processes in meiosis that create genetic differences among cells?
Answer:
independent assortment during anaphase and crossing over during prophase
Explanation:
genetic material is swapped during crossing over
chromosomes from either mother or father could be put into any gamete during independent assortment
The two processes in meiosis that create genetic differences among cells are independent assortment and recombination.
What are recombination and independent assortment?DNA fragments are broken and recombined during the recombination process to create novel allele combinations. The genetic variation that results from this recombination process at the gene level reflects variations in the DNA sequences of various species.
Recombinant and novel gene combinations are produced by the independent collection of genes.
The connected genes do not demonstrate independent assortment, since they are inherited together. More parental types and fewer recombinant are created because connected genes lack independent assortment.
Thus, the two processes are independent assortment and recombination.

ATP → ADP + P is an example of an endergonic reaction, because there is an output of the energy.
An endergonic reaction is one that calls for free electricity to proceed. An example of an endergonic response of biological hobby is photosynthesis. Photosynthetic organisms conduct this response by using using sun photons to drive the discount of carbon dioxide to glucose and the oxidation of water to oxygen.
Within the exergonic response, the reactants are at a higher unfastened power degree than the goods reaction is going energetically downhill. In the endergonic response response, the reactants are at a decrease loose power stage than the products response goes energetically uphill.
The endergonic reactions of photosynthesis and chemosynthesis allow creatures at the bottom of the energy pyramid to live to tell the tale and to feed organisms like ourselves, who get their strength by means of breaking down sugars and fats to free up that stored power.

A student decided to find the density of her house key to try and identify the type of metal from which it is made. She found the volume of the key to be 5 mL and the mass to be 39.5 g. Using the chart above, from which type of metal is the key made?
Going by the density of the key which is 7.9 g/mL, the key is likely made from iron.
DensityThe density of a substance is the ratio of the mass of the substance and of its volume.
The density of a substance can be mathematically expressed as:
Density = mass/volume.
Considering the key in question whose volume is 5 mL and mass is 39.5 g. The density can be determined as:
Density of the key = 39.5 /5
= 7.9 g/mL
In order to determine the nature of the metal that the key was made from, one would need to check the table of density of metals. Any metal whose density corresponds with, or is close to 7.9 g/mL would be the metal that the key is made from.
From a chart of density, the metal with a density of 7.9 g/mL is iron.

How does the temperature of water change if you heat it after it has alread
reached the boiling point?
The temperature of water does not change.
This is because when water is heated to its boiling point of 100 degrees Celsius, it usually takes more energy to turn a liquid into a gas, so the extra heat helps with that conversion. The temperature of water, even if it reaches its boiling point, does not change until all the water evaporates into the atmosphere. Depending on the type of container, the temperature will rise when the water runs out.

This plant cell has been sliced in half and you are looking into one of the halves. How would you describe the structure of the cell?
The fundamental unit of life in species belonging to the kingdom Plantae is the cell. They are eukaryotic cells, which have specialized components called organelles and a real nucleus that performs several duties. They also have a cell wall, which serves as support for the structure.
Structure of plant cell :Plant cells have a cell wall, a large central vacuole, and plastids like chloroplasts. The cell wall is a substantial, rigid covering that encloses and physically supports the cell. Outside the cell membrane is where it is found. Turgor pressure against by the cell wall is maintained by the central vacuole.
After mitosis, plant cells divide in half by building a new cell wall (cell plate) between daughter nuclei. The phragmoplast, a cytoskeletal component, receives golgi-derived vesicles that are then transported there and fused to form the cell plate.
