A. Scientific research
B. Collective agreement
C. A fact
D. Scientific consensus
Scientific experts are the pannel of the researchers involved in studies and analysis. The expert agreeing on a theory based on the evidence is called scientific consensus. Thus, option D is correct.
What is scientific consensus?
The scientific consensus is the agreement where the scientists and researchers from various fields agree on a proposed idea. They are evaluated by the majority agreeing with a particular theory.
The publications, academic discussion, and peer review accomplishes the consensus and act as a quality checker that evaluates the data and the facts based on the evidence presented.
Therefore, in scientific consensus, scientific experts agree on a particular theory.

4. What is the mass of N2H4 gas in a 350.0 mL container at 50.0 °C, if the pressure of the gas is
885.0 torr?
Answer:
0.36g
Explanation:
Given parameters:
Volume of N₂H₄ = 350mL = 0.35dm³
Temperature of container = 50°C = 50 + 273 = 323K
Pressure = 885torr;
760torr = 1atm
885torr = [tex]\frac{760}{885}[/tex] = 0.86atm
Unknown:
Mass of the compound = ?
Solution:
The mass of the compound can be derived using the expression below;
Mass = number of moles x molar mass
molar mass of N₂H₄ = 2(14) + 4(1) = 32g/mol
To find the number of moles;
PV = nRT
n = [tex]\frac{PV}{RT}[/tex]
P is the pressure
V is the volume
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = [tex]\frac{0.86 x 0.35}{0.082 x 323}[/tex] = 0.01mole
So,
Mass = 0.01 x 32 = 0.36g

Which statement about the waves shown is true?
The statement about the wave that is true is wave 3 has lowest frequency. The correct option is C.
What is frequency?The frequency of a repeating event is the number of occurrences per unit of time. It is distinct from angular frequency and is sometimes referred to as temporal frequency. The unit of frequency is hertz, which equals one event per second.
In science and engineering, frequency is an important parameter used to specify the rate of oscillatory and vibration phenomena such as mechanical vibrations, audio signals (sound), radio waves, and light.
The relationship between frequency and wavelength is inverse. The wavelength of the wave with the greatest frequency is the shortest.
One-half the wavelength equals twice the frequency. As a result, the wavelength ratio is inverse to the frequency ratio.
Thus, the correct option is C.

Which correctly lists three places that fresh water is found?
Answer:
Ice caps and glaciers - 69%
Groundwater - 30%
Surface water - less than 1 %
Explanation:
Fresh water is a type of water, found in nature, in which there is no salt. It is water suitable for consumption (provided it is treated) for humans and animals. Fresh water is also used in agriculture. Only about 2.5% of the water found on our planet is sweet. It is mainly found in polar caps and glaciers, groundwater, surface water.
With the growth of the world population, fresh water has become increasingly scarce. Overuse, waste and water pollution are the main problems related to fresh water today.
As it is a precious and scarce mineral resource, society must be aware that, in order not to run out of water in the near future, it is necessary to avoid waste, use it rationally and do not pollute rivers, lakes and water sources.

What genetic condition results in the trait indicated by the blue color being
expressed in the individuals shown here?
Answer:
ressessive
Explanation:
because it is what present by its phenotype
Blue color being expressed in the individuals shown here is recessive trait.
What is recessive trait?In terms of genetics, the term "recessive" describes the connection between an observed trait and the two inherited forms of a gene associated with that feature.
Each gene has two alleles that an individual inherits from each parent. When a characteristic is recessive, both of the (recessive) alleles of the gene that causes the trait must be present for the trait to manifest. When there is only one copy of an allele, it has no effect at all.
This is in contrast to a dominant trait, which can only be expressed when one of the two alleles is present.
Therefore, Blue color being expressed in the individuals shown here is recessive trait.

A scientist places four identical cells into four different liquids, each with different concentrations of magnesium. Cell Description of Liquid Result W Slightly more magnesium than the cell Took in magnesium X The least amount of magnesium Took in magnesium Y Slightly less magnesium than the cell Took in magnesium Z The most amount of magnesium Took in magnesium Which shows evidence of active transport?
Answer:
The correct option is Z
Explanation:
Active transport can be described as the movement of molecules against a cell's concentration gradient; meaning the movement of molecules across the cell's membrane from a region of lower concentration to a region of higher concentration. From this, it can be deduced that to have active transport in the description in the question, the "body" (the cell or the liquid) with the most amount of magnesium took in more magnesium (showing movement against concentration gradient as the magnesium moved from the least side to the most side). Thus, the correct option is Z

Explanation:
When studying animal behavior, the distribution of organisms within a choice chamber can be studied to identify animal preferences. 20 Isopods are placed in a 2-choice choice chamber. A cotton ball dampened with distilled water is placed in Chamber A; A dry cotton ball is placed in Chamber B. After 15 minutes 2 Isopods are located in Chamber B, and 18 isopods are found in Chamber A. Perform the chi-squared test to determine if the distribution of isopods is significant or due to random chance.a. chi-squared is 1.20, no it is not significant.
b. chi-squared is 8.42, no its not significant.c. chi-squared = 12.8, yes it is significant.d. chi-squared is 18.59, yes it is significant.
Answer:
The correct option is c. chi-squared = 12.8, yes it is significant.
Explanation:
Available data:
20 Isopods are placed in a 2-choice choice chamber. Different conditions were applied15 minutes later: 18 isopods are found in Chamber A and 2 Isopods are located in Chamber B.H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
Chi square= ∑ ((O-E)²/E)∑ is the sum of the terms
O are the Observed individuals: 2 in chamber B, and 18 in chamber A.
E are the Expected individuals: 10 in each chamber
X² = ∑ ((O-E)²/E) = ((2 - 10)²/10) + ((18 - 10)²/10) = 6.4 + 6.4 = 12.8
X² = 12.8
Freedom degrees = K – 1 = 2 - 1 = 1(K = Independent variables = dry cotton and wet cotton)
Significance level, 5% = 0.05 Table value/Critical value = 3.8412.8 > 3.84 meaning that the difference between the observed individuals and the expected individuals in each chamber is statistically significant. Not probably to occur by random chances.
There is enough evidence to reject the null hypothesis. The distribution of isopods is statistically significant.80 POINTS! Refer to the Newsela article "PRO/CON: Should We Abolish the Electoral College?"
