What do you think is the reason for the similarities between the three mammal (the pig, monkey, and human) body segment forms (c) shown below?
Using careful observation, describe at least two differences between these two limbs. Start with the hand bones.
The wo differences between the hand bones of human and cat limbs are- Number of digits: Human hands have five digits (four fingers and a thumb), while cat paws have four digits. This difference in digit number is due to evolutionary adaptations that have occurred in the two species over time.
What are limbs?Limbs are the appendages of the body that are used for movement and manipulation. In humans and most animals, limbs typically consist of bones, muscles, tendons, ligaments, and other connective tissues that work together to produce a wide range of movements and actions.
Shape and size of bones: The bones in human hands are relatively long and slender, with distinct shapes and sizes for each digit. In contrast, the bones in cat paws are shorter and thicker, and the digits are more uniform in shape and size.
This difference in bone structure reflects the different functions of human hands and cat paws, as human hands are adapted for manual dexterity and fine motor control, while cat paws are adapted for hunting and climbing.
It's important to note that there are many other differences between human and cat limbs, including the structure and function of muscles, tendons, and ligaments, as well as the range of motion and flexibility of the joints.

3. Which statement describes starches, fats, proteins, and
nucleic acids?
A) They are used to store genetic information.
B) They are complex molecules made from smaller
molecules.
C) They are used to assemble larger inorganic
materials.
D) They are simple molecules used as energy
sources.
Answer:B
Explanation: Because if u Look at Protein Carbohydrates Nucleic acid and fatty acid actually they are polymers made up of small units called monomers.Option C is incorrect because these are organic molecules containing carbon so we cannot say that it will form an inorganic structures and the other option says about genetic information so genetic information is only determined by Nucleic acids not fatty acid, Protein or Carbohydrates and last option D is incorrect because nuclei acid didn't provide energy.
The statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).
What are Nucleic Acids ?Nucleic acids are naturally occurring chemical compounds that break down to form a mixture of phosphoric acid, sugars, and organic bases (purines and pyrimidines). Nucleic acids are essential data-transmitting molecules of the cell, and, as they also direct the course of protein synthesis, they control the inherited characteristics of living things.
The two essential categories of Nucleic acids are Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). DNA is the master prototype for life and contains genetic material in all free-living organisms and various viruses.
RNA is the genetic material of some viruses. It is also found in all living cells which plays an important role in certain processes like making proteins.
Thus, the statement which describes starches, fats, proteins and nucleic acids is they are complex molecules made from smaller molecules. So, the correct option is (B).
