Answer: The correct answer is -
D. a slight limp
Explanation:
Acquired trait is any feature that an organism develops after birth and it is non heritable that is not passed from one generation to the next generation.
On the contrary, inherited trait (such as fur color, length of ears) is present from birth and it is inherited from parents through genetic material.
Slight limp is basically uneven walking that results due to some injury in the legs or because of physical limitation. It means that it is developed after the birth.
Thus, option D) is the right answer.
cholesterol
testosterone
beeswax
Cholesterol is the lipid that acts as a chemical messenger in the body, playing a role in cell signaling and hormone production. Therefore, the correct answer is option b.
Cholesterol is the lipid that acts as a chemical messenger. Cholesterol is a sterol, a type of lipid molecule, and it serves as a precursor for the synthesis of various important chemical messengers in the body, including hormones like testosterone and estrogen.
These hormones play key roles in various physiological processes, such as regulating the development and function of reproductive organs, and they act as signaling molecules that help coordinate different activities within the body. Cholesterol also plays a vital role in the structure and function of cell membranes.
The other options (adipose tissue and beeswax) are not typically considered chemical messengers in the same way that cholesterol and hormones are.
Therefore, the correct answer is option b.

tools to avoid rusting?
To prevent kitchen tools made from iron from rusting, one can paint them, use stainless steel alloys, or store them in a way that prevents contact with air and water.
To help preserve kitchen tools from rusting, there are few precautions that you can take. The first method is painting iron tools. Water and oxygen come into touch with iron and cause rust, but a coat of paint can stop this from happening. The iron is immune to rust as long as the paint is still on it.
Another strategy is alloying the iron with other metals to form, for example, stainless steel, an iron alloy containing a small amount of chromium. Chromium tends to collect near the surface, where it erodes and forms a passivating oxide layer that protects the iron from rusting.
Lastly, storing your iron kitchen tools under kerosene or mineral oil or in sealed containers could prevent rust by limiting their contact with air and water.

B. Inflammation triggers the production of white blood cells
C.Inflammation drops the pH of blood
C.Inflammation raises the pH of blood
Answer:
The correct answer is option A. "Inflammation keeps harmful substances away from healthy cells".
Explanation:
Inflammation is a defense mechanism of the body that occurs as a result of tissue damage. Inflammation protects the body from infection and injury by keeping keeps harmful substances away from healthy cells. During inflammation the small branches of the arteries are enlarged and the capillaries allow the infiltration of fluids and proteins. This process isolates the injured region, protecting the healthy cells and promoting the immune response to act in the damaged region.
Answer:
Dissimilar organisms might have evolved from a distant, common ancestor.
Explanation:
First of all we should know species. Species is considered as a basic unit of taxonomic classification of an organism.
Initially, the scientists are agreed on this phenomenon that all distinct species are evolved gradually from common ancestor. Today, the species which are different from each other just like hummingbirds, humans and whales are from the same ancestor but with the time passage genetic mutation occurs and at the end dissimilar organisms we can see in our environment/surroundings.
