Answer: The correct answer is-
A. organs, but no true body cavity.
Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).
Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.
Body cavity is present between the external wall of body and the intestine and it baths the different body organs.
Thus, option A) is the right answer.
Answer:
Option A
Explanation:
All bilateral organisms have coelomates (cavity). However a Pseudocoelomate organism have a false cavity. By false cavity, we mean that there is a body cavity which is filled with fluid and all internal organs bathe in it including alimentary canal system , reproductive system etc. Unlike a coelom, Pseudocoelomate organism do not have body cavity completely lined with mesodermal cells.
hence, option A is correct
Answer:
Animilia
Explanation:
Answer:Cell membrane
Explanation:Forms a boundary between a cell and the surrounding environment and controls the passage of materials into and out of the cell.
Answer:
Cell Membrane (These are from my personal Biology Notes)-
Explanation:
Found in all cells (FIAC)
Selectivity permeable
Embedded with proteins
Regulates what enters or exits the cell
Phospholipid bilayer
Polar: head is hydrophilic (Likes water)
Nonpolar: tail; hydrophilic
Answer:
The answer is: The formation of the ATP energy storage molecule and the reduced electron carrier NADPH.
Explanation:
It turns out that part of the light energy absorbed by the pigments in the leaves is converted in a different way, into chemical energy.
Light-dependent reactions use light energy to form two molecules necessary for the next stage of photosynthesis: the ATP energy storage molecule and the reduced NADPH electron carrier.
The answer is: The formation of the ATP energy storage molecule and the reduced electron carrier NADPH.
b.oxygen, nitrogen, and sulfur.
c.hydrogen, oxygen, and nitrogen.
d.carbon dioxide, hydrogen, and phosphorus.
The right answer is A.carbon, hydrogen, and oxygen.
Carbohydrates are composed of 3 types of atoms: carbon (C), oxygen (O) and hydrogen (H). Their general formula is written: Cn (H2O) n, (hence the name carbohydrate). There are 2 major carbohydrate families: Simple carbohydrates (monosaccharides and polysaccharides) and complex carbohydrates.
Several foods of different origin contain carbohydrates: sugar, fruits, milk, bread, dough, rice, pulses ... Their role is to bring energy to each of our cells.
The elements found in carbohydrates are carbon, hydrogen, and oxygen. No matter if it's a simple sugar like glucose or a complex carbohydrate like cellulose, these elements remain consistent. Thus, the answer is (a) carbon, hydrogen, and oxygen.
The carbohydrates you're referring to contain three common elements: carbon, hydrogen, and oxygen. These three elements are consistent across all forms of carbohydrates, regardless whether it's a simple sugar (monosaccharide) like glucose or a complex carbohydrate (polysaccharide) like cellulose.
For example, glucose (C6H12O6) is made up of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms. The ratio of hydrogen atoms to oxygen atoms in carbohydrates always approximates 2:1, similar to water. This is a key characteristic that defines carbohydrates.
So, the answer to your question is option (a) carbon, hydrogen, and oxygen.
