Answer:
Explanation:
Cutting a log is a physical change. Cutting would give rise to a new wood piece .
So.. no new substance is formed so its a physical change.
Dissolving Sugar
A mixture of sugar and water can be separated by using heat.
Heat will separate the water and sugar using a process called Evaporation.
Baking A Cake
When baking your cake it is a chemical change because you can't get your ingredients back. We know that it is a chemical change because heat energy is involved.
. Boiling Water
Boiling water is a physical change.
it can be changed back to its original form by freezing.
Answer: The basic tissue structure of the mucosa layer of the alimentary canal consists of:
--> mucous membrane
--> lamina propria
--> muscularis mucosa
Explanation:
The MUCOUS MEMBRANE forms the innermost layer of the alimentary canals which includes the stomach and the duodenum (small intestine) . It's major functions is protection, secretions and absorption. The type of mucous membrane found in the stomach and duodenum is the Columnar epithelial cells. Not numerous gastric glands are situated below the surface in the mucous membrane of the stomach. They consist of specialised cells that secrete gastric juice that aids in the digestion of food. While the duodenal mucosa consists of mucous producing goblet cells. These cells produce a viscous, alkaline mucus that protects against the acidic gastric juices and pepsin. The folding of these mucosal cells (microvilli) provides a large surface area to optimize nutrient absorption.
The LAMINA PROPRIA: This layer separates the mucous membrane and the muscularis mucosa. It is made up of connective tissues which supports the blood vessels that nourishes the inner epithelial layer. In both the stomach and duodenum, digested nutrients are absorbed into the capillaries.
MUSCULARIS MUCOSA: This is made up of thin layer of smooth involuntary muscles. The contraction and relaxation of these muscle layers occurs in waves, which push the contents of the tract onwards. This type of contraction is called peristalsis which occurs in the duodenum. While in the stomach, these muscles allows for the churning motion characteristic of gastric activities.
The mucosa layer in the alimentary canal comes into direct contact with food and consists of three layers: epithelium, lamina propria, and muscularis mucosae. The stomach mucosa secretes mucus, hydrochloric acid, and digestive enzymes, while the duodenum's mucosa contains glands that neutralize stomach acid, protecting the intestinal wall and enabling absorption.
The mucosa layer in the alimentary canal is the innermost layer that comes into direct contact with food. This layer consists of three sublayers: epithelium, lamina propria, and muscularis mucosae. The epithelium is made up of simple columnar cells responsible for secretion and absorption. The lamina propria is composed of loose connective tissue supporting the epithelium, and the muscularis mucosae is a thin layer of muscle that causes local movement of the mucosa.
The mucosa in the stomach has a special epithelium that secrets mucus, hydrochloric acid, and digestive enzymes, aiding in both protection and the breakdown of food. Its unique feature is the presence of gastric pits and parietal cells that secrete hydrochloric acid.
In contrast, the mucosa in the duodenum, part of the small intestine, contains Brunner's glands which produce an alkaline secretion rich in bicarbonate and mucus. The purpose of this is to neutralize stomach acid and protect the intestinal wall, enabling absorption to take place.

Aristotle illustrates virtue in a way distinct from what one is usually taught in school, but it is much closer to how one thinks on a regular basis. One is usually taught that courage is the contrary of cowardice, and generosity is the reverse of miserliness and others.
Although, Aristotle illustrates virtue as the mean between the two extremes, which requires to be avoided. For Aristotle, virtue is the golden mean between the two extremes. Though the mean is not a strict arithmetic mean. Virtue comes in between the two extremes, but where it actually comes depends on a very large extent to a particular situation.
Answer:
Aristotle defines a virtue as a habit that requires practice.
Explanation:
Moreover, as with any habit, becoming virtuous requires practice, repeatedly doing similar kinds of things until it becomes second nature.
Answer:
The correct answer is - Venom enzyme inhibitors.
Explanation:
The snake venoms are the complex mixtures of phospholipase A2s, disintegrins, serine proteases, C-lectins, and metalloproteases, and others. The snake venom phospholipase A2s (svPLA2s) enzymes found in most of the families of venomous snakes that cause anticoagulant effects, cardiotoxicity, neurotoxicity, and cytotoxicity, and other effects.
In antivenom, there are Venom enzyme inhibitors other than antibodies that help inneutralizing these enzymes by weakening or inhibiting these toxic actions.
Why do you think this is happening? (Things
to think about: habitat destruction, erosion,
pollution, invasive species, human impact.)
Answer:
Well the most common is habittat destruction. With the number of humans only growing, more land is needed and habitat desturctions occur. Lack of food is also a problem, as some crops don’t grow as much so the bee’s food source is smaller which leaves thousands dead. Also if the food source doesn’t run out, there are pesticides sprayed and the bees will die if eaten one which the chemical properties in a pesticide will kill. Also if not used, littering, if you dump it into a water source, the water gets contaminated and the bees could die from that, or the water spreads ano the flower would receive this chemical property, which could kill the Bee’s food source, or the flower doesn’t die but when the bees consume it, the bee will die.

Archaeopteryx
Enantiornithes
Paleognathae
Answer:
A bird or feathered dinosaur is Archaeopterix.
Explanation:
Archeopteryx is an extinct genus of primitive birds, with intermediate characters between feathered dinosaurs and modern birds.
Archeopteryx lived in the Upper Jurassic Period about 150 million years ago, in what is now southern Germany, during a time when Europe was an archipelago of islands in a shallow warm tropical sea, much closer to the equator of what is now.
Answer:
A bird or feathered dinosaur if Archaeopteryx.
