How did the peppered moth's environment change, and what caused this change?

Biology
1 answer:
a_sh-v [17]3 years ago
7 0

Answer:

Due to the industrial revolution, smoke caused the environment of the peppered moths to change to a darker/black color. This resulted in a higher prevalence of black peppered moths over white peppered moths.

Explanation:

The dark environment made it so black peppered moths had the favorable trait while the white moths, who previously had the advantageous trait due to old environments being light in color, now had a deletirous trait. Predators could now more easily see the light colored moths, so they were more likely to be killed than the dark colored moths, so more dark colored moths were able to reproduce. This lead to a larger prevalence of dark peppered moths.

Descending colon is found between the transverse and sigmoid colon on the left side of the abdominal cavity.

<h3>What are the components of large intestine?</h3>

The cecum, colon, rectum, and anus are the components of the large intestine. Mesenteries are tissue folds that hold the colon and rectum in the belly.

Caecum: The colon and ileum (the last part of the small intestine) are connected by a pouch-like channel called the cecum.

Colon: The longest part of the large intestine is the colon. There are 4 sections in the colon-

  • Ascending colon: The colon begins with the ascending colon. It is located on the abdomen's right side. It continues upward until it reaches the hepatic flexure, a bend in the colon.
  • Transverse colon: Following the ascending colon and hepatic flexure is the transverse colon. The upper portion of the abdomen is where it is located. The splenic flexure, a bend in the colon, marks its conclusion.
  • Descending colon: The transverse colon and splenic flexure are followed by the descending colon. The abdomen's left side is where it is located.
  • Sigmoid colon: The colon's final section, the sigmoid colon, joins to the rectum.

Rectum: The lower portion of the large intestine that joins the sigmoid colon is known as the rectum. Its length is roughly 15 cm (6 in). It takes waste from the colon and keeps it there until the anus allows it to leave the body.

Anus: The aperture at the bottom end of the rectum known as the anus is where feces exits the body.

How do cells maintain water balance through osmosis?
neonofarm [45]
Water then moves from cell to cell through the root cortex by osmosisalong a concentration gradient; this means that each cell is hypertonic to the one before it. In the centre of the root the water enters the xylem vessels. Water may move by diffusionthrough the cell walls and intercellular spaces.

Cholesterol's main role in the membrane seems to be:
olga nikolaevna [1]

Answer:

E) Improve membrane fluidity

Explanation:

Cholesterol constitutes the basic structural element of the skeleton of cell membranes. Without their reinforcement, the membranes would become extremely fluid and lose their consistency. Cholesterol is found in the esterified membranes in its hydroxyl group (OH): with fatty acids, mainly oleic and linoleic, or as cholesterol sulfate. The cholesterol-sulfate polar group is disposed on one of the faces of the membrane that interacts with other polar groups in that area, while its bulky hydrophobic portion is embedded between the apolar parts of the lipids that form the membrane skeleton and They fulfill many other functions, among which the reduction in the permeability of protons and sodium ions, and their participation in signal transmission. Cholesterol is also essential in phagocytosis processes carried out by cells to capture many nutrients and, in general, for the function of cleaning up organic waste produced by macrophages.

The membranes must have a fluid structure so that the integrated proteins can move "horizontally" to interact with their ligands and with other proteins. The fluidity is given by unsaturated fat. With the excess of saturated fat, the membranes become rigid, but only with the necessary unsaturated fat the membranes are extremely fluid and very sensitive to temperature changes. Cholesterol stabilizes the structure of the membranes; In order for them to have the correct structure, they must have the correct proportions of saturated, unsaturated fats and cholesterol. The membranes produced in the laboratory without cholesterol are unstable to temperature changes, drastically modifying their fluidity against the small temperature changes that occur in the physiological range.

In addition to its functions in cell membranes, cholesterol is an important product that metabolism uses as a raw material to make other compounds:

*Bile salts

*Sex hormones

*Hormones of the adrenal cortex (corticosteroids)

*Vitamin D (Calciferol)

What is pseudopodia?​
vlabodo [156]

Answer:

Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move.

Explanation:

Pseudopodia are temporary and cytoplasm-filled parts of the cell membrane that are able to change their form in order to move. They are used in some eukaryotic cells to move around or to eat. Most cells that do this are called amoeboids. The amoeba is a common example. ... Pseudopods can also capture prey by phagocytosis.
