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.

Which is the least important base in the anticodon? (Remember to count 5' to 3'!)
a) First
b) Second
c) Third
d) They are all equally important
Answer:
c
Explanation:
The least important base in the anticodon is the third base.
The first two bases of anticodons largely determine the amino acid that would be formed in most cases. The third base can be any of the purine or pyrimidine bases and the amino avid would remain the same. For example, the anticodon UCA, UCG, UCC, and UCU all code for the amino acid Serine.
The correct option is, therefore, c.
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?

What are variables?A variable is a value that can change in programming in response to conditions or information passed to the program. A typical program consists of data used by the program while it is running and instructions that tell the computer what to do.
Variable values are typically initialized to "0" or some default value because the actual values will be supplied by a program's user, and constant or fixed values, which never change, make up the data.
Constants and variables are typically referred to as particular data types because each defines and restricts the data's form. These are some examples of data types: an unrestricted string of text characters or an integer expressed as a decimal number.
Therefore, the correct option is D. if the experiment continued under the same conditions.

When an LDL particle is taken up by the cell, what impact will this have on the regulation of de novo cholesterol synthesis?
A. Transcription of HMG-CoA reductase will be elevated
B. SREBP will be inhibited by Insig in the endoplasmic reticulum
C. HMG-CoA reductase will be dephosphorylated
D. SREBP will be active in the nucleus
Answer:
C. HMG-CoA reductase will be dephosphorylated
Explanation:
When a low density lipoprotein particle is taken up by the cell, the impact it will have on the regulation of de novo cholesterol synthesis will be HMG-CoA reductase being dephosphorylated.
HMG-CoA( 3-hydroxy-3-methyl-glutaryl-CoA reductase) is an enzyme which aids the synthesis of lipids. When the lipids are produced and taken up by the cells then the effect of the synthesis stops to avoid excess synthesis and to allow for the action of enzymes which will act ok them in the cells . This is why it leads to a dephosphorylation of the enzyme which stops the action.
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.

When Skeletal muscle contracts an arrangement of the alternating light and dark bands traversing each skeletal muscle cell changes. Which of the following statements is not correct?(a) The dark A bands will remain a constant length(b) The space occupied by the H zone will not change(c) The light I bands will shorten(d) The z lines come closer together(e) The I band consists solely of thin actin filaments
Answer:
(b) The space occupied by the H zone will not change
Explanation:
The sarcomere is the contractile unit in a skeletal muscle.Thick myosin myofilaments are located in the central region of the sarcomere, which corresponds to the A band. Thin filaments united to the Z lines, extends to the interior of the A band until they reach the border of the H band. I band is formed solely of thin actin filaments, belonging to two sarcomeres adjacent to a Z line. (option (e) is correct)When the muscle contracts, the muscular fiber gets shorter and thicker due to the reduction in length of the sarcomere. The H line and the I band get shorter (Option (b) is not correct, but option (c) is correct). The Z lines get closer to the A band, meaning that they get closer to each other (Option (d) is correct). A band keeps constant in length (Option (a) is correct)This change is produced by movement mechanisms that involve a change in the relative position of actin and myosin filaments.which is worst type of oil

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.

Is the hypothesis about ice cream scientifically testable?
Answer:
No, this is not a testable hypothesis.
Explanation:
Hypothesizing regarding ice cream flavor preferences and texture is not scientifically testable since it inquires for a subjective statement from the subject who would be taking part in the experiment. Scientific method is a set of objective steps taken to formulate some conclusion about an observation or a phenomenon.
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.
