Geologists determine the
geological history of an area by
examining rock layers in geologic
columns. The diagram shows
three geologic columns from the
same region that have not been
overturned.
A.
Place an arrow at each rock
layer boundary to represent a
missing layer of rock in each
of the three columns.

Answers
The sample columns have two missing layers as follows:
Column 1: Layers 3 and 8 are missing. Column 2: Layers 1 and 7 are missing. Column 3: Layers 1 and 5 are missing. What is geology?Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.
In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.
According to the previous process, it can be inferred that the missing layers in each column are:
Column 1: Layers 3 and 8 are missing. Column 2: Layers 1 and 7 are missing. Column 3: Layers 1 and 5 are missing.Note: This question is incomplete because the graph is missing. Here is the graph.

Construction of a new road system splits a population of a rare snail species into three sub- populations, J, K and L. Each of these populations is reproductively isolated.
The table shows the sizes of the three populations immediately after the building of the road

p the relative frequency of the dominant allele of a gene
q the relative frequency of the recessive allele of this gene.
The three areas of habitat remained the same as each other over the ten year

What is the most likely explanation of the data shown below?
A 3 column table with 6 rows. Column 1 is labeled Year with entries 0, 1, 2, 3, 4, 5. Column 2 is labeled Dark moths with entries 50 percent, 59 percent, 68 percent, 80 percent, 95 percent, 100 percent. Column 3 is labeled Light moths with entries 50 percent 41 percent, 32 percent, 20 percent, 5 percent, 0 percent.
a.
There has been a drought in the area that is affecting all life forms.
b.
The population of natural predators of the moths has gotten smaller.
c.
The moths are living in an environment with light trees.
d.
The moths are living in an environment with dark trees.
Answers
Answer:
The correct answer is D. The moths are living in an environment with dark trees.
Explanation:
In general, the data shows the population of light moths increases over time, while the population of light moths decreases to the point it disappeared. This would likely occur if there was an environmental change that allowed dark moths to have survival and reproductive advantage over light moths. This includes if the trees are dark because in this scenario dark moths have a better chance to avoid predators and reproduce, while light moths would have a lower chance to survive because predators can find them easily and this leads to the decrease in light moths population shown in the chart.
Which planet has a dramatic greenhouse effect, no moons and acid in its' clouds? *

Answer: venus
Explanation: Venus' thick atmosphere traps heat creating a runaway greenhouse effect – making it the hottest planet in our solar system with surface temperatures hot enough to melt lead. The greenhouse effect makes Venus roughly 700°F (390°C) hotter than it would be without a greenhouse effect.
What is unique about active sites?
A: active sites provide cells with energy.
B: active sites are specific to certain substrates (reactants).
C: active sites store the genetic information of cells.
Answers
The Unique feature of Active sites is that active sites are specific to certain substrates (reactants)
Active sites are specific regions of an enzyme where substrate molecules bind in other to bring about a chemical reaction.
The active site is made up of amino acid which forms temporary bonds with the substrate otherwise known as the binding site and the residues which brings about a reaction of that substrate.
Active sites are specific to certain substrates (reactants). Therefore, option (B) is correct.
Active sites are vital to enzymes, proteins that aid biological processes. They have a distinctive form that matches their substrate molecules. This specificity allows only particular substrates to bind to and interact with the active site, catalysing processes. This is called the "lock and key" or "induced fit" model.
Enzymes' catalytic action depends on active sites. A substrate attaches to an enzyme's active site and changes conformation, lowering the reaction's activation energy. This speeds up the reaction. After the reaction, the products are released and the enzyme's active site can bind to another substrate. Therefore, option (B) is correct.

Nature vs. Nurture both influence the observed traits of an organism.
The controversy between nature and nurture have been an ongoing discourse for many years. It is believed that the traits of an organism are dependent on genes inherited from the parents. Another school of thought believes that environment alone has the sole influence over the traits of an organism.
However, most scientists today are of the opinion that the influence of nature and nurture are intertwined and they both work together to influence the traits exhibited by any organism.

In the 1920s, Frederick Griffith He was studying two different strains of a bacterium, called R (rough) strain and S (smooth) strain. He injected the two strains into mice. The S strain killed (virulent) the mice, but the R strain did not (non-virulent). Griffith also injected mice with S-strain bacteria that had been killed by heat. As expected, the killed bacteria did not harm the mice. However, when the dead S-strain bacteria were mixed with live R-strain bacteria and injected, the mice died.
