Did the results of the cross match your prediction? If not, why do you think that was the case?
In 1978, scientists studied how the fitness of marine sticklebacks would be affected if they were introduced into a freshwater environment. They collected 90 male and 90 female sticklebacks from a marine population and 10 male and 10 female sticklebacks from a freshwater population. The 200 sticklebacks were introduced into a freshwater environment that had no stickleback fish previously.
Recently a scientist decided to repeat this study, but relocated a population of sticklebacks from a freshwater environment into a marine environment. Which of the following best predicts how the frequency of the allele would change over time if a population of sticklebacks from a freshwater environment was placed into a marine environment?
The frequency of alleles in the population started low and continued to increase over time.
What is frequency of alleles?The frequency of alleles refers to the ratio of the number of times an allele occurs to the copies of all the alleles at that particular genetic locus in the given population.
We can see that the sticklebacks had a greater number of those introduced from marine to fresh water hence of the 200 sticklebacks, the frequency of alleles in the population started low and continued to increase over time.

What do you think the hardest part of measuring the growth of a forest would be? Explain your answer.
Answer:
You can measure the growth of individual trees over time by measuring their diameter. ... Trees tend to grow irregularly at the base, so to determine a more accurate measure of diameter, foresters will measure the diameter of the tree at 4.5 feet above the ground

Tracking Changes to Your Trees and Woods: Measuring growth

In previous posts, we recommended that landowners get out into their woods to keep an eye on any changes that might be taking place, whether that be changes to the health of your trees or boundary problems. We also suggested you keep track of physical changes to your trees by watching them grow and change over time. First we gave you some tools to identify the trees in your woods. This month’s post will introduce ways you can measure the growth of individual trees.
You can measure the growth of individual trees over time by measuring their diameter. Many of us learned to count the rings of a tree to determine how old they are. The other secret in the rings of our trees is how wide they are. Generally, healthy, not crowded trees will put on more growth in diameter over time; thus, the rings will be wider when they are healthy. If you are astute, you may be asking how in the heck you measure the diameter of solid wood. That is where a handy tool comes into play, called the diameter tape. With this tool, you are technically using the circumference of the tree, and the number on the tape has markings that indicate the diameter (circumference divided by Pi (3.14)). You can purchase a diameter tape (D-tape) from forestry suppliers, or you can make your own using a simple length of rope or ribbon using the method shown in this publication . Trees tend to grow irregularly at the base, so to determine a more accurate measure of diameter, foresters will measure the diameter of the tree at 4.5 feet above the ground. When you record the diameter of trees, you can follow the growth of those trees over time, and you can calculate other important measures of your woods. As a reminder, healthy trees will grow faster (and fatter) in diameter each year than trees that are crowded and unhealthy.
Organisms that obtain and ingest organic molecules for their nutrition are classified as.
Answer:
Also refered to as consumers, heterotrophs are organisms that obtain their energy (nutrition) from organic compounds/materials. In other words, they are organisms that are unable to produce their own food (unlike autotrophs) and therefore have to consume/ingest organic compounds as a source of energy.

Which of the following is an example of a nonspecific immune response? I. White blood cells that invade the area of a cut in the skin II. An injury triggers mast cells to release histamine, causing inflammation III. Killer T-cells destroy pathogens by recognizing proteins on cell surfaces.
Nonspecific is the innate immune response that is present since birth. White blood cells and mast cells are examples of non-specific immunity.
What is a nonspecific immune response?The non-specific immune response is the immunity present in the child from his/her birth and is a generalized response that employs white blood cells and mast cells for conferring the pathogens.
It is innate immunity that protects from the invasion of pathogens and provides the first line of defence by forming barriers.
It includes the invasion of the white blood cells in the area of any cut or injury or the release of the histamine from the mast cells in an injured area for the inflammation pathway.
Therefore, the statement I about white cells and II about mast cells are examples of the non-specific immune response.

Which agricultural practices result in methane emission?
Agricultural sources include manure pits and cow burping from “enteric fermentation,” which results from the digestive process of cattle.
What do you mean by enteric fermentation?Enteric fermentation is a digestive process by which carbohydrates are broken down by microorganisms into simple molecules for absorption into the bloodstream of an animal.
Enteric fermentation is a natural part of the digestive process in ruminant animals such as cattle, sheep, goats, and buffalo. Microbes in the digestive tract, or rumen, decompose and ferment food, producing methane as a by-product.
Enteric fermentation occurs when anaerobic microbes, called methanogens, decompose and ferment food present in the animal's digestive tract producing compounds that the animal host then absorbs.

Why are start and end amino acids encoded by only one codon?
Answer:
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

Strawberry jelly is a very strong solution of sugar. By contrast the cytoplasm in bacteria is a much weaker solution. The cell wall of bacteria is made up of a PARTIALLY permeable membrane. Would water flow from the microbe to the jam, or from the jam to the microbe by osmosis? Explain
Since the concentration of the jelly is higher than the concentration of the bacterial cytoplasm, water would flow from the microbe to the jam by osmosis.
What is Osmosis?Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration through a semi-permeable membrane.
