A student will measure and record the growth (in height) of two flowering plants every other day for 20 days. Each plant will receive 200mL of water each day, but only one plant will receive 10mL of fertilizer. What is being tested? Do flowering plants grow better with salt water? Does fertilizer help a plant grow taller? How tall do these flowering plants grow? How much fertilizer do flowering plants need?
Answer:
Does fertilizer help a plant grow taller?
Explanation:
Every experiment begins with an observation, which then leads to a scientific question that can be tested. In this question, a student measures and records the growth (in height) of two flowering plants every other day for 20 days. He then waters each flowering plants with same amount of water (200mL) but adds 10mL fertilizer to only one group of flowering plant.
This experimental set up implies that fertilizer is the independent variable or manipulated variable of the experiment while the dependent/measured variable is the growth (height) of plants.
N.B: 200mL of water is a constant or controlled variable
Hence, based on the identification of the independent and dependent variables, it can be said that the student is testing IF fertilizer will improve the growth in height of the flowering plants, hence, the scientific question will be: DOES FERTILIZER HELP A PLANT GROW TALLER?
Which of the following accurately describes Poiseuille's law?a. blood flow is not related to resistance. b. if resistance increases, flow increases. c. if resistance increases, flow decreases. d. viscosity of the blood is not related to flow. e. pH of the blood influences flow.
Answer: Option C.
if resistance increases, flow decreases.
Explanation:
if resistance increases, flow decreases describe Poiseuille's law because it explain the relationship between fluid flow and the viscosity of the fluid, length and width of the turning. The law describe fluid flow is related to length and radius of tubing and viscosity. Increase in resistance will result in decrease in flow rate because flow and resistance are reciprocally related in one way or the other.

Scientific theories are explanations for naturally occurring events or phenomena. Although scientific theories require extensive observations and experimentation, they can change over time as new evidence is discovered. Scientific laws are principles that are also based on extensive observations and experimentation. Although scientific theories can develop into laws, a theory can only be declared a law if it is proven to be without exception under certain stated conditions. Which of the following is true regarding scientific theories,laws, and knowledge? A. New scientific knowledge is gained by memorizing scientific theories and laws. B. Scientific knowledge must be proven by both scientific theories and laws. C. Scientific theories can lead to scientific knowledge, but scientific theories are not related to scientific knowledge. D. Scientific theories and laws develop from the acquisition of scientific knowledge.

Would you be able to survive if your body only had one type of cell?
Answer:
yes
Explanation:
you would be able to survive
If the human's body only had one type of cell, they will not be existing. Hence, the answer is no.
The human body is the most complex of all living organisms. It is made up of trillions of cells that are organized into tissues, organs, and organ systems with each organization carrying out different functions. Without these organizations, humans will not be able to carryout essential life processes and as such, not able to survive.
If the trillions of cells are just one type of cell, then, only one tissue, organ, and organ system can be formed. The cells had to differentiate in order for them to be organized into different tissues, organs, and organ systems
In other words, if your body had only one type of cell, the different biological processes being carried out would not be possible and you would not survive.

Hopefully you are getting the picture that science is a dynamic process, always changing as new information arises. Any individual experiment may include one or more of the components that have been discussed because there is no one formula for a successful scientific inquiry and no single rule book that is rigidly followed. So what does all this experimentation and data collection lead to? Firstly, research results have no impact if they are not shared with a community of peers and eventually society as a whole. Scientists working in the same research area often check each others results by repeating similar experiments. There is a great deal of both cooperation and competition in the scientific community. Contrary to popular belief science is in fact an incredibly creative process, that includes elements of challenge, surprise, careful planning, patience and persistance. It is the inquisitive mind that drives scientific progress.
Now that you have been more thoroughly introduced to the nature of science, lets try that survey from the beginning of this unit again.

Humans autosomal cells have two copies each of 23 unique chromosomes. Match each cell division event and cell type according to the number of chromatids present.
23 Chromatids, 46 Chromatids, or 92 Chromatids
Spermatozoa
Ootid
Anaphase of mitosis
Oogonium prior to S phase
Answer:
Spermatozoa: 23 chromatids
Ootid: 23 chromatids
Anaphase of mitosis: 92 chromatids
Oogonium prior to S phase: 46 chromatids
Explanation:
1) Spermatozoa, also known as sperm cell is a haploid gamete (n) that results from the meiotic division of a dipoid reproductive cell. Since there are 23 pairs of chromosomes or 46 chromosomes in human somatic cells, there will be 23 chromosomes in the spermatozoa. Also, meiotic division occurs twice and separates sister chromatids in meiosis II. Hence, spermatozoa will contain 23 chromosomes (n) with 1 chromosome each i.e. 23 chromatids
2) Ootid is a haploid cell that arises from the second meiotic division of a secondary oocyte. A primary oocyte, with 46 chromosomes/92 chromatids, undergoes meiosis I to produce secondary oocyte with 23 chromosome/46 chromatids, which in turn undergoes meiosis II to produce ootid with 23 chromosomes/23 chromatids (each chromatid is an individual chromosome).
3) Mitosis is the cell division that produces two identical diploid (2n) daughter cells. Note that, 46 chromosomes get replicated to form 92 chromatids. In the anaphase stage of mitosis, sister chromatids get pulled apart to opposite poles but still remain in the cell as cytokinesis is yet to occur.
4) Oogonium is the diploid (2n) cell that gives rise to primary oocyte via mitosis. Prior to the S phase where chromosomes replication occurs, Oogonium cell will contain 46 chromosomes and 46 chromatids.

Diploid eukaryotic cells have two haploid sets of chromosomes, one contributed by the mother, the other contributed by the father.A. TrueB. False
Answer:
True.
Explanation:
Diploid eukaryotic cells have two haploid sets of chromosomes, one contributed by the mother, the other contributed by the father because sexually producing organisms like humans normally have diploid set of chromosomes which is contributed each by the two parent. The cells in humans that that are haploid set of chromosomes are the sex cells which is egg and sperm.
The egg and sperm fuse to together through reproduction a d fertilization occur when the sperm fertilizes the egg and the haploid set of chromosomes dude to form diploid set of chromosomes which is the offspring .

What is the independent variable? *
Answer:
TYPE OF LIQUID SUBSTANCE RECEIVED
Explanation:
The independent variable in an experiment is the variable that the experimenter deliberately changes or manipulates in order to bring about a response in the dependent variable/measured variable.
In this experiment, the TYPE OF LIQUID was changed for each group of plant in order to see how it affects how the plants grew. Hence, the TYPE OF LIQUID is the independent variable while the dependent variable is the plant growth, which is dependent on the independent variable.

What is Biological community?
A biological community is made up of things like a forest of trees and underbrush plants that is home to various animals and is anchored in bacterial and fungal-rich soil.
Each species in a community fills a certain ecological niche. A species' interactions with other individuals in the community, such as rivalry, predation, parasitism, and mutualism, are included in its niche.
The positions along the food chains that indicate which organisms in a community consume which other organisms are referred to as trophic levels.
