When graphing data, what will make it
more precise?
A. using larger units
B. making it cover most of the graph
C. using a bar graph
D. connecting all the points plotted
Answer:
A. using larger units
Explanation:
Graphs can be used to display large amounts of numerical data and to portray the relationships between numerical values of different variables
When graphing data, what will make it more precise would be to ensure that it covers most of the space on the graph sheet. The correct option would, therefore, be B.
Using larger units may result in inaccurate plotting of small variablesNot all data can be represented as a bar graphConnecting all the points plotted has no bearing on the precision of a graphMaking your graph to cover, at least, 2/3 of the graph space will ensure that your plots are visible and lead to a more precise graph.

La influencia que tiene la temperatura en la reproducción de los paramecios, en muestras de agua estancada
Answer:
Para un paramecio la temperatura óptima requerida para llevar a cabo sus funciones metabólicas (incluida la reproducción) se encuentra entre 24 °C y 28 °C
Explanation:
Los paramecios (género Paramecium) son protozoarios, es decir, organismos microscópicos del reino protista. Un paramecio es un organismo unicelular que puede llevar a cabo todas las funciones esenciales de un modo funcionalmente similar a una célula animal. Los paramecios pueden reproducirse tanto de manera sexual como asexual (bipartición). Estos organismos viven en cuerpos de agua dulce rica en nutrientes orgánicos como estanques, charcos, regiones de ríos parcialmente estancadas, etc. En estos ambientes los paramecios se reproducen de un modo óptimo a una temperatura entre 24 °C y 28 °C, donde pueden llegar a dividirse hasta 4 veces al día.

Explain and illustrate using chemical pathways how excessive alcohol intake can lead to; 1.Hypoglycemia
Answer: Alcohol can influence the blood sugar levels causing hypoglycemia.
Explanation:
Hypoglycemia is a condition in which the body experiences low blood sugar levels. Alcohol abuse can be one of the reasons for hypoglycemia. The occasional drinkers are affected negatively by this. It increases the secretion of insulin hormone which is a hormone necessary for keeping a balance of blood sugar levels in the body. The excess secretion of insulin can lead to decrease in blood sugar concentration and resulting in hypoglycemia. This can lead to type 1 diabetes.

The diagram below shows a diploid cell with two homologous pairs of chromosomes. Due to independent assortment and crossing-over, the possible allelic combinations that could be found in gametes by the meiotic division of this cell are _________________.
A
Bb, Dd, BB and DD
B
BD, bD, Bd and bd
C
BBDd and BDbd
D
Bd and bD only
Due to independent assortment and crossing-over, the possible allelic combinations found in gametes by the meiotic division of this cell are B and D can be on one chromosome, while b and d can be on the other. Therefore, the correct answer is (B) BD, bD, Bd, and bd.
What is crossing-over?Crossing-over is a process that occurs during meiosis, the cell division process that produces gametes (sperm and egg cells) in sexually reproducing organisms. During crossing-over, homologous chromosomes exchange genetic material, resulting in the creation of new combinations of alleles.
What is the law of independent assortment?The law of independent assortment is a fundamental principle in genetics that describes how different genes are inherited independently. Gregor Mendel first proposed this principle.

HELP WILL GIVE BRAINLIEST IF CORRECT: What effect do plants' roots
have on rock?
a. They hold it together
b. They weather it
c. They cause it to undergo chemical changes
d. They break it apart
Answer: C
Explanation: Reason why is because whenever the roots put pressure on the rock it cracks open and all the minerals release so it has to be going thru a chemical change because the roots receive the minerals from the rock or stone ...
Answer:
im guessing d but im not sure..,
Explanation:
When these roots grow, they exert pressure on the rock around them, causing the gaps to widen or even crack. Plant roots can also weather rock through chemical processes. When dead roots decompose, they release carbon dioxide; this is sometimes converted into carbonic acid, which chemically breaks down rock into soil.

The number of chemical industries along Florida's rivers is increasing. What is the most
likely consequence of this increased industrialization?
O a decrease in the amount of water pollution
O an increase in the amount of water available for recreational use
an increase in the destruction of natural food webs
O a decrease int he amount of water needed by industry
Answer:
The correct answer would be - an increase in the destruction of natural food webs.
Explanation:
Increasing chemical industries near the river cause harmful effects to the environment by various means, including air pollution, dumping untreated chemical or industrial waste, and wastewater in the river. This will lead to a lack of potable water, contamination of the food chain, destruction of biodiversity, and many more.
The destruction of biodiversity can be caused by the increasing the unbridled growth of phytoplankton, eutrophication process that will consume more oxygen and cause algal bloom and decrease the oxygen in the water and destroys the organism and natural food web.

Which of these is not a human cause of extinction of species?
Choose the correct answer.
A) Clearing of an area for farmland.
B) A dam built in a river for city water usage.
C) Competition for food resources with another native species.
D) The introduction of a new predatory species to an island by boat.
The statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.
What is species?Species may be characterized as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce fertile offspring. The process of speciation is generally mediated through the species.
In the present time, the human causes of the extinction of species are majorly popular. It includes the clearance of an area for farmland and industrialization, the building of a dam for city water utilization, the introduction of a new predatory species to an island by boat, and many more.
But the process of competition for food resources with another native species is ultimately the behavior governed by the respective species itself without the interference of humans.
Therefore, the statement that does not represent a human cause of the extinction of species is the competition for food resources with another native species. Thus, the correct option for this question is C.
