Scenario: Before the industrial revolution in England the predominant peppered moth had light colored
wings. After the industrial revolution more dark colored moths appeared until they were the dominant form of
the moth. The major predators of these moths were sparrows that relied on sight to identify and eat the
moths.
The dark colred moths began to increase in numbers in the forest of the industrial area because
A They blended in with the dark tree trunks and were camouflaged from the sparrow predators
B They were not as sensitive to the sooty pollution as the light colored moths
C The reproduction rate was slower than the light colored moths
D The dark colored moths tasted bad as compared to the light colored moths

A macromolecule that is composed of only carbon, hydrogen, and oxygen and is specifically used as a short-term energy source for building the structural components of living things is Carbohydrates.  

Carbohydrates are one of the biomolecules that are made up of only elements such as Hydrogen, Carbon, and Oxygen. Each molecule’s type has its unique specific function. Some significant functions of carbohydrates are mentioned as follows:

Thus, we can conclude that the correct answer is carbohydrates and thus, option D is the correct answer.

Answer:

a. capillary action of liquid in plant stems

Explanation:

Vascular plants need to transport water from roots to stem and leaves. For this purpose, water molecules adhere to xylem cell walls (xylem is one of the two classes of transport tissues in higher plants). Adhesion, also known as capillary action, is a mechanism produced when water molecules cling to xylem cell walls. Thus, adhesion can be defined as a molecular mechanism caused by the attraction between molecules, in this case, between molecules of the xylem and water molecules.

Answer:

Mobility.

Explanation:

Mobility is the term used for all types of movement such as walking , running, swimming and flying etc. Mobility refer to the movement, those organisms which has the ability to move from one place to another is known as mobile organisms e.g lion, birds, tiger and humans etc, while on the other hand those organisms that are unable to move from place to place is called immobile organisms.

Answer:

adherence of phagocytes to the lining of blood vessels

Explanation:

The correct answer for the medical/biological definition of margination would be the adherence of phagocytes to the lining of blood vessels.

Margination is a process that takes place when injuries occur in complex animals. During the early phase of inflammation of the injury site, the blood capillaries dilate and the white blood cells (phagocytes and leukocytes) adhere to the endothelial cells of blood vessels.

Answer:

Annual plants live for one growing season and then die, while perennials regrow every spring. ... The difference, according to plant geneticist Siegbert Melzer and his team, comes down to two critical flower-inducing genes that, when turned off, can make an annual plant regrow every year.

Answers

-Worldwide sea level increased

-river plains drowned

Explanation

Glaciers are large blocks of ice and with all the ice melting the water levels rose worldwide. (Correct Answer)

When sea levels rose it caused river plains to be flooded. (Correct Answer)

Glaciers are made from freshwater so when they melt the salinity in estuaries does change. (Not a correct Answer)

Erosion definitely affected river valleys. Alpine glaciers create valleys and even help erode valleys. With Alpine glaciers melting this slows the process of that erosion and with them melting the river valleys will eventually flood. (Not a correct Answer)

Answer:

1, Planting trees

2. Actions that reduce carbon dioxide emission

Explanation:

Ally can reduce the amount of carbon dioxide in the atmosphere in two ways

1. By planting trees or reforestation

Trees generally act as a sink for carbon through photosynthesis. Hence, planting more trees means that more carbon dioxide in the atmosphere will become fixed into the trees leading to the reduction of the gas in the atmosphere.

2. Reducing emission

To further reduce the amount of carbon dioxide in the atmosphere, the rate of emission of the gas has to be reduced. Actions such as the burning of vegetation and fossil fuels need to be reduced because they increase the emission of carbon dioxide gas into the atmosphere. The actions can be substituted for less or no carbon dioxide emitting alternatives.

When less carbon dioxide is emitted into the atmosphere and more is being fixed into trees, the overall concentration of the gas in the atmosphere will reduce greatly with time.

Answers and explanation:

Most of the cells in the human body are somatic cells and have 23 pairs of chromosomes (46 chromosomes in total) and are thus called 'diploid cells'. The only cells that have 23 single chromosomes are the gametes, which are haploid cells - the reason behind this is that gametes in females (ovum) need to be fertilized by the gametes present in males (sperm) to form a new being: the zygote.

Mitosis and meiosis are both processes in which the cells are divided, but they are quite different. In Mitosis, the somatic cells divide themselves to generate two daughter cells that are equal to the cell that has divided. In Meiosis, the diploid cells that generate the gametes, divide into four daughter cells, which will all have half of the chromosomes (the four of them will be haploid cells with 23 chromosomes each).

1. How many daughter cells are made during mitosis? 2.

During meiosis? 4.

2. In humans how many chromosomes will be in a daughter cell after mitosis? 46. After meiosis? 23.

3. What happens during interphase before both mitosis and meiosis can begin?

Interphase is the name given to the part of the cell cycle in which the cells are not dividing themselves. In this phase, cells spend most of their lives, and they use it to do things such as obtaining nutrients and metabolizing them so they can make use of them to carry on with their specific tasks, which vary depending on the type of the cell. In a very specific part of Interphase called the S phase, the cell duplicates its DNA - this leads to the cell having 2 copies of the same information, which will be important when cell division comes (in Mitosis, each daughter cell will get one complete copy; in Meiosis, each daughter cell will have half of a copy).
