which of the following explains how scientists know that current global warming is related to human activities. there wasn't carbon dioxide in the atmosphere in the past, there was more methane in the atmosphere 6,000 years ago, increased carbon dioxide in the atmosphere is not carbon-14, there is more water vapor in the atmosphere today than the past
Answers
C. Increased carbon dioxide in the atmosphere is not carbon-14.
Explanation: Scientists know the increased carbon is from human activities because it is not the normal carbon 14 released by natural process. When we burn coal, oil, and natural gas, we leave an imprint on the atmosphere of what we call negative carbon-14, or less carbon-14. Because fossil fuels are so old, there's no carbon-14 left, it's all decayed away.
Scientists are aware that current global warming is caused by human activities. Carbon-14 is not present in increased levels of carbon dioxide in the atmosphere.
What is greenhouse gases?Climate change entails long-term shifts in temperature and weather systems. Although these changes are natural, anthropogenic activities have been the principal driver of climate change since the 1800s, owing primarily to the use of fossil fuels (such as coal, oil, and gas), which emit heat-trapping gases. The long-term warming of the planet's average temperature is referred to as global warming. Despite the fact that this warming trend has been going on for a long time, the rate of acceleration has accelerated in the last century due to the use of fossil fuels. As the world's population has increased, so has the consumption of fossil fuels.To learn more about global warming, refer to:

Explanation:
To approximate the actual concentration of enzymes in a bacterial cell, assume that the cell contains equal concentrations of 1,000 different enzymes in solution in the cytosol and that each protein has a molecular weight of 100,000. Assume also that the bacterial cell is a cylinder (diameter 1.0 m, height 2.0 m), that the cytosol (specific gravity 1.20) is 20% soluble protein by weight, and that the soluble protein consists entirely of enzymes. Calculate the average molar concentration of each enzyme in this hypothetical cell.
Answers
Answer:
2.4 × 10⁻⁶ M
Explanation:
Molar concentration = no of moles of solute (enzymes)/volume of solvent(cystosol)
Let V = volume of solvent = volume of cystosol = πd²h/4 where d = diameter of cell = 1.0 m and h = height of cell = 2.0 m
Concentration of enzymes, C = n/V where n = no of moles of enzymes
Also, n = m/M where m = mass of all enzymes and M = molecular weight of protein = 100,000
Note that the solvent for the enzymes is cystosol, since they are dissolved in it.
Density of cystosol,ρ = specific gravity of cystosol in g/cm³ = 1.20 g/cm³.
Now, ρ = m'/V where m = mass of cystosol and V = volume of cystosol
m' = ρV
m' = 1.20V
Given that 20 % of the cystosol is protein and all protein are enzymes, the mass of enzymes is thus m = 0.2m' = 0.2 × 1.20V = 0.24V
C = n/V
= m/MV
= 0.24V/100000V
= 2.4 × 10⁻⁶ mol/cm³
= 2.4 × 10⁻³ mol/dm³
= 2.4 × 10⁻³ M
This is the concentration of all the 1000 enzymes.
So, the concentration of one enzyme is 2.4 × 10⁻³/1000 M = 2.4 × 10⁻⁶ M

It must be unicellular, and it might spend part of its life away from water.
It must have a nucleus, and it might gather food or make food for itself.
It must make its own sugars, and it might use them to make spores for reproduction.
Answers
Answer:
3. It must have a nucleus, and it might gather food or make food for itself.
Explanation:
The main type of protist that has both flagella and cholorphyll is the unicellular Euglena genus. This protist, (like all protist) has a nucleus and has both plant AND animal characteristics. It has the ability to absorb food, but can also create food for itself.
Certainly an interesting little creature
By the way, I can verify that this is correct because I got a 100% on the assignment.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~`
Let me know if you have any questions! Have a nice day if you're reading.
It must be able to form colonies, and the colonies might move around to follow the sun. Option 1 is correct.
A protist that has both flagella and chlorophyll is likely photosynthetic and capable of self-sustenance. The presence of flagella suggests mobility, which can be advantageous for positioning the chlorophyll-containing cells to receive optimal sunlight for photosynthesis. However, while flagella and chlorophyll are indicative of certain characteristics, the options provided contain some inaccuracies:
Forming Colonies and Sun Tracking: The protist's mobility with flagella could allow it to form colonies where individual cells can work together to optimize light exposure. Sun tracking is possible, but not all protists with these features do it.
Unicellular and Life Away from Water: Protists can be unicellular or multicellular, but the presence of flagella and chlorophyll doesn't necessarily dictate its life away from water. Many protists live in aquatic environments.
Nucleus and Food Production: Having a nucleus is common for eukaryotic cells, including protists. Chlorophyll indicates the potential to produce its own food through photosynthesis.
Sugars and Reproduction: Chlorophyll enables photosynthesis, allowing the protist to make its own sugars. The production of spores for reproduction might be a characteristic, but it's not directly linked to having both flagella and chlorophyll.
In conclusion, while the presence of flagella and chlorophyll indicates potential mobility and photosynthesis, it doesn't necessarily dictate specific behaviors like colony formation, sun tracking, or reproductive methods. Protists with these features can exhibit a wide range of characteristics and behaviors within their ecological niches.

A sample of milk is tested for its bacterial content in a plate count assay. A one-milliliter sample of the milk is diluted in a 1:10 dilution series. One milliliter of the third dilution tube is plated in a pour plate. After incubation, the plate has 54 colonies, indicating that the original milk sample contained how many CFU/ml?
Answers
After incubation, the plate has 54 colonies, indicating that the original Milk sample contained 540,000 CFU/ml.
The equation for calculating the CFU/mL in the original sample is:
CFU/mL = (number of colonies on plate x dilution factor) / volume of the culture plated
Here,
Number of colonies on plate = 54
Volume of the culture plated = 1 mL
The original sample is serially diluted in a proportion of 1:10, that is 1/10
So the dilution of first tube = 1/10
From the first tube, the culture in again diluted in a proportion of 1:10
So, Dilution of second tube = 1/10
The total dilution of tube 2 will be the product of the dilution of tube 1 and tube 2.
So, total dilution of tube 2 = 1/10 x 1/10 = 1/100
Similarly, the total dilution of tube 3 will be 1/1000 and tube 4 will be 1/10000
The sample is plated from tube 4, and therefore the total dilution of tube 4 is used for the calculation of bacterial concentration.
Dilution factor = Reciprocal of dilution
So, dilution factor of tube 4 = 10000 = 104
Substitute the values in the equation:
CFU/mL = ( 54 x 104) / 1 = 54 x 104 = 540000 cells/mL

What is the probability that unicorn offspring will have a white horn? Brown horn?
Answers
The probability that the offspring will have a white horn is 3 out of 4, or 75%.
In unicorns, the trait of having a white horn (W) is considered dominant over having a brown horn (w). When two heterozygous unicorns, each carrying one dominant white horn allele (W) and one recessive brown horn allele (w), are crossed, the probability of their offspring having a white horn can be determined using Punnett squares.The possible genotypes of the parent unicorns are Ww and Ww. When these genotypes are crossed, the potential offspring can inherit one of the following genotypes: WW, Ww, Ww, or ww. Out of these options, three of them (WW, Ww, Ww) contain at least one dominant white horn allele, resulting in a unicorn with a white horn. Therefore, the probability that the offspring will have a white horn is 3 out of 4, or 75%. This calculation is based on the assumption that the genetic traits are inherited independently and follow Mendelian inheritance patterns.For more questions on genotypes

define permeability ?
Permeability is the capacity of a porous material to transmit a fluid; it is expressed as the velocity with which a fluid of specified viscosity passes through a sample with a certain cross section and thickness under the influence of a given pressure. Permeability is mostly determined by the size and form of the pores in the substance, as well as the size, shape, and packing arrangement of the grains in granular materials such as sedimentary rocks.
The darcy is the standard unit of permeability, which is defined as the flow of one cubic centimetre of fluid (with a viscosity of one centipoise) per second through a sample one square centimetre in cross-sectional area at one atmosphere per centimetre of thickness.
