A group of people have white blood cell (WBC) counts that are from 4,500 to 10,000 WBC/ml. All cell count values in that range are equally abundant in the population. What is the mean WBC count in the population?
Answers
Answer:
7250 WBC/ml
Explanation:
The mean of any value is the average of a certain amount of given values. When this is taken into cognizance, to get the mean White Blood Cell count of the population, given two ranges, is to add and divide both together. This gives us
10,000 + 4,500 = 14,500 WBC/ml
The mean then is
14,500 / 2 = 7250 WBC/ml
Therefore, the mean White Blood Cell count in the population is 7250 WBC/ml
How does elevation affect climate?
A. It determines whether winds will blow inland bringing moist air, or towards the ocean bringing dry air.
B. It determines how much solar energy an area receives and thus how hot it will be.
C. It determines how dense the air is, and how much heat energy the air can hold.
D. It determines whether winds will blow inland bringing moist air, or towards the ocean bringing dry air.
Answers
Altitude affects weather determines how dense the air is and how much heat energy the air can hold.
Option C is the correct one.
What is the relationship between authority and climate?The relationship between climate and altitude is manifested through variations in atmospheric pressure and temperature. Although higher locations are closer to the sun, they tend to receive less heat, becoming colder, in addition to having a smaller thermal amplitude (temperature variation).
With this information, we can conclude that Higher elevations cause temperatures to drop because the higher up in the atmosphere you go the colder it gets due to air pressure in turn causing precipitation to freeze creating snow.

True
Explanation:
In nuclear fission, an unstable atom separates into two or more shorter, more steady fragments, discharging energy. Matter is not preserved throughout this process because some of the weight of the merging nucleus is transformed to power, which would be discharged. Fusion is the mechanism through which massive stars generate enormous energy amounts.

Research the practical for osmosis and write notes on it.
Answers
Investigate the effect of a range of concentrations of salt or sugar solutions on the mass of plant tissue
Scientists investigate the effects of osmosis on living cells. They either:
Observe (with a microscope),cells or tissues placed in solutions of different concentration.
Measure changes in cylinders or discs of fresh potato or beetroot. Cylinders will have a larger mass than discs, so scientists will have larger measurements to work with.
The following experiment investigates the effect of different concentrations of sucrose on potato tissue. It could also be carried out using salt – sodium chloride solution – instead of sucrose.
Aims of the experiment
To investigate the effect of a range of sucrose solutions on the mass of potato cylinders.
To determine the concentration of the cell sap of potato cells.
Method
Prepare a range of sucrose (sugar) solutions. The concentration of a solution is measured in moles per cubic decimetre written as mol dm-3. For example, in this experiment your range could be from 0.2 mol dm-3 to 1.0 mol dm-3. A 1.0 mol dm-3 solution of sucrose will contain up to 342 g of sucrose per dm-3. A 1.0 mol dm-3 solution of a substance contains one mole of the substance per dm3 of a solution, or one mole per litre of solution.
Set up a series of boiling tubes with each of these solutions. Also, set up one containing distilled water. This will have a concentration of sucrose of 0.0 mol dm-3 and will act as the control in the experiment.
Make sure each tube is labelled with the concentration.
Carry out the investigation. Prepare a blank results table before you begin. Make sure when weighing the potato cylinders, that their masses are not mixed up when recording them. Each cylinder will have a different mass before and after the investigation.
For each sucrose concentration, repeat the investigation for several potato cylinders. This allows you to make the experiment more repeatable – not all potato cylinders might behave in the same way. Making a series of repeat experiments means that any anomalous results can be identified and ignored when a mean is calculated.
Risks
Make sure that the potato is placed on a ceramic tile when using the cork borer – do not cut the potato cylinders towards your hand.
Care must be taken when using the scalpel.
Wear eye protection when using chemical solutions.
This experiment shows the effect of osmosis on plant tissue. The cylinders will decrease or increase in mass if they lose or gain water by osmosis.
The effects on plant tissues at a cellular level can be observed using a microscope. Another way of looking at osmosis in plant cells is to mount a piece of onion skin, or beetroot on microscope slides in drops of different concentrations of sugar or salt. Observe the cells for a few minutes. It is easy to see the process of plasmolysis in beetroot because the cell sap is red.
explain two situations on a pedigree that would allow you to determine the genotype of an individual with the dominant phenotype
Answers
1) If the individual with the dominant phenotype has a parent with the recessive phenotype, the genotype of the individual is heterozygous (Aa).
2) If the individual with the dominant phenotype has offspring with the recessive phenotype, the individual must be heterozygous (Aa).
The two situations on a pedigree that would allow you to determine the genotype of an individual with the dominant phenotype.
Situation 1: Identify the individual with the dominant phenotype (let's call them Individual A).Look for the parents of Individual A.
If one of the parents has the recessive phenotype (aa) and the other parent has the dominant phenotype (AA or Aa), then Individual A must be heterozygous (Aa). This is because the dominant phenotype is only expressed when at least one dominant allele is present.Situation 2: Identify the individual with the dominant phenotype (Individual B).
Observe the offspring of Individual B.
If Individual B has offspring with the recessive phenotype (aa), it means that Individual B must be heterozygous (Aa). This is because to have offspring with the recessive phenotype, both parents must contribute a recessive allele.
By analyzing the presence of the recessive phenotype in the parents or offspring of an individual with the dominant phenotype, we can determine their genotype as heterozygous (Aa).

The patient has been diagnosed with no Golgi apparatus in the cells. Does this present a problem with the diffusion of glucose across the plasma membrane?
1) No, this does not present a problem because the Golgi apparatus has nothing to do with the maintenance of the phospholipid bilayer and the diffusion of glucose into the cell.
2) Yes, this presents a problem because the Golgi apparatus packages up the transport proteins to be taken to the membrane and embedded in the phospholipid membrane to assist glucose diffusing into cell by active transport. Glucose would not be able to diffuse into the cell.
3) Yes, this presents a problem because the Golgi apparatus packages up the transport proteins to be taken to the membrane and embedded in the phospholipid membrane to assist glucose diffusing along its concentration gradient into the cell. Glucose would not be able to diffuse into the cell.
Answers
No, this does not present a problem because the Golgi apparatus has nothing to do with the maintenance of the phospholipid bilayer and the diffusion of glucose into the cell. That is option 1.
What is Golgi apparatus?The Golgi apparatus is an example of the membrane bound organelles that are located within the cell which assists in the transport of materials such as synthesized proteins from within the cell to the exterior.
The molecules that are responsible for the transport of glucose is the glucose transporters (GLUTs) located within the cells, which transport glucose across the plasma membrane by means of a facilitated diffusion mechanism.
It can be concluded that when a patient is diagnosed with absence of Golgi apparatus, to transport of glucose should not be affected because there is not connection between Golgi apparatus and glucose transport within the cells.

How does fossils record help scientists observe changes in organism over time ?
Answers
As the world changes, plants and animals change with it. Aside from a few living fossils, the species we see today are very different from species that lived in the past.
What is the minimum age of a fossil?A living being that lived more than 11 thousand years ago is considered a fossil, that is, before the Holocene, which is the current geological epoch.
Ancient remains or evidence, but less than 11,000 years old, such as sambaquis, are classified as subfossils.
The dating of a fossil can be done based on the already known percentage of Carbon-14 (C14) in relation to Carbon-12 (C12) of living matter (without decomposition).
Thus, the fossil record can be used to show that organisms changed to meet new conditions.

Answer:
The correct answer is option D. Light and some other factors are necessary for chlorophyll production
Explanation:
By this experiment, it is clear that light is the major factor that helps in the production of chlorophyll in seedlings or plants. In this study, placing the seeds in the light turns 75 seedlings green which is possible by the production of the green pigment, chlorophyll only. So, it is proved that light is a key factor in the production of chlorophyll.
Besides light, there must be some other factors (mineral nutrition and chemical metabolites) that also play role in the production of chlorophyll or increase or decrease of the chlorophyll production as few seedlings did not turn green in the study.
