The chart shows embryos of different animal phyla.Based on the evidence of their embryos, which pair of phyla are most closely
related?
O A. Echinodermata and Annelida
O B. Mollusca and Arthropoda
O C. Mollusca and Echinodermata
O D. Annelida and Chordata
Answers
Invertebrates with an exoskeleton, segmented bodies, and paired jointed appendages are known as arthropods.
Molluscan animals have soft bodies that are triploblastic, bilaterally symmetrical, and coelomate. Malacology is the study of Mollusks. They are slow-moving invertebrates with a thin fleshy envelope or mantle that protects the visceral organs.
What are the similarities between Mollusca and Arthropoda?
- They are triploblastic creatures.
- They are animals with bilateral symmetry.
- They're coelomates.
- They are organized at the organ system level.
Thus, we can conclude that option B, Mollusca, and Arthropoda are correct.

Correct Answer: A). Dissecting microscopes and compound light microscopes
After magnification the object appears larger in size that is measured by the magnifying power. It can be found out by dividing the focal length of the scanning object to the focal length of the eye piece. From the above given option the greatest difference that is found in the magnifying power is between the dissecting microscope and compound light microscope.
Hence, the correct answer would be option A.
Amongst the options provided, the biggest difference in magnification power is between transmission electron microscopes and dissecting microscopes. Dissecting microscopes provide lesser magnification but enable three-dimensional viewing, while electron microscopes offer superior magnification and detail, at the cost of the specimen's life.
Therefore, the correct answer is option b.
The greatest difference in magnifying power lies between b. transmission electron microscopes and dissecting microscopes.
Dissecting microscopes provide lower magnification, typically ranging between 20 to 80 times the object size, and are suitable for viewing larger objects such as tissues (Fig 3.2b). They also offer a three-dimensional view of the specimen.
On the other hand, transmission electron microscopes utilize a beam of electrons instead of light.
This mechanism facilitates much higher magnification and detail while providing superior resolving power. However, this method requires the destruction of the specimen and cannot be used for viewing living cells.

If the shape of an enzyme changes then the enzyme will no longer be able to perform its function.
Enzymes can be described as bio-catalysts which usually speed up a chemical reaction. Each enzyme has a particular substrate which fits into the active site of the enzyme. Every enzyme needs a particular temperature and pH for its functioning. If the shape of an enzyme changes, then it will no longer be able to perform its function and will become denatured.

Answer:
The glucose is the primary source of energy, which yields ATP in the presence of oxygen. The continuous intake of carbohydrates provide streamlined flow ATP that is meeting the demands of prolonged exercises.
Explanation:
Carbohydrate loading is defined as the increase in the intake of carbohydrates. Carbohydrates are stored in the form of glycogen, which is then broken down to yield glucose. Glucose is necessary to drive the vital functions of the body, such as respiration.
An athlete performing extensive exercise requires streamflow of ATP to fulfill the energy demands of the body. The metabolism of glucose provides ATP. The carbohydrates are the rich source of glucose, which in the substrate level undergoes oxidative phosphorylation and citric acid cycle. Oxygen plays a primary role in the breakdown of carbohydrates as glucose. It plays a crucial role in accepting electrons in the electron transport chain to synthesize ATP.
Thus, the continuous supply of oxygen is necessary for the metabolism of macromolecules. ATP in a higher amount is required by athletes to improve muscle performance. Thus, the stored glucose and continuous supply of oxygen are necessary to generate energy molecules.

(3) It is starch that was produced during digestion
(4) lis carbon dioxide released by respiration
Answers
Answer:
The correct option is D. It is carbon dioxide released by respiration.
Explanation:
The process by which ATP is abundantly formed in organisms is termed as cellular respiration. Cellular respiration can be described as a process in which carbon dioxide and water are produced from glucose and oxygen. ATP molecules are synthesized by this process which are used for cellular activities.
Hence, the substance X in the investigation shows carbon dioxide which was produced when the yeast cells began to respire. Yeast cells can respire either in the presence of oxygen or without oxygen.
