Answer:

The answer is 648

Explanation:

8 * 3 = 24

24 * 3 = 72

72 * 3 = 216

216 * 3 = 648

The given trend for the bacteria population is a geometric sequence with initial amount of 8 (a0) and the common ratio equal to 3. The amount of bacteria at any time t is,
                                          at = (a0) x r^(t - 0)
Substituting the given,
                                           at = (8) x 3^(4 - 0)
The numerical value for at is 648. Thus, there will be 648 bacteria after 4 weeks.

MaRussiya [10]

Rock A = It is a metamorphic rock that  experienced tremendous heat  and  pressure due to massive,  moving tectonic plates.

Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.

Rock B = It is a sedimentary rock made  primarily from lithification of  organic material.

Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.

Rock C = It is an igneous rock that  was formed above  Earth’s surface.

Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.

Which statement best describes both insulin and glucagon? They both provide structural support, but only insulin is a carbohydra
Tomtit [17]

Answer:

They are both hormones that regulate blood-sugar levels

Explanation:

Insulin is a hormone that controls the blood glucose level. It released in the blood stream when the glucose level increases after eating food. It is produces by pancreas, insulin helps the glucose to enter the body's cells where it can either be stored for future use or can be used for energy.

Glcogen  is produced by alpha cells of pancreas, it is a peptide hormone. Its main function is to raise the concentration of fatty acids and glucose in the bloodstream. It is one of the main catabolic hormone of the body

As per the above mentioned statements, the option 'They are both hormones that regulate blood-sugar levels' is the correct answer.

Fill in the missing words. naturalselection foundereffect geographicallyisolated species evolution
grandymaker [24]

Hi!


The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect , allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.


In terms of population genetics, founder effect is when there is a loss of genetic diversity as a result of the establishment of a new population by a relatively few individuals. Following such an establishment, natural selection is the process  which results in the genes of the fittest individuals of the population being selected over generations. This process ultimately results in evolution, and over time may give rise to new species. Geographical isolation is the physical separation of a population from another owing to geographical changes in the terrain or area. If two populations of the same species are geographically isolated, there is a great chance over time they may evolve into two different species.


Hope this helps!

Katena32 [7]

So let’s substitute that into the third equation and solve for B. B = H + T B = 9 + (9 + 1/2B) B = 18 + 1/2B Then subtract 1/2B from both sides: 1/2B = 18 Multiply both sides by two: B = 36 Now we know the value of B and the value of H. Substitute this back into the second equation and solve for T. T = H + 1/2B T = 9 + (1/2)36 T = 9 + 18 = 27 Step 4: Plug all values of H, T, and B into the final equation. Total length of fish = H + T + B Total length of fish = 9 +27 + 36 = 72.
