Answer:
Shark skin has been used by many cultures as sandpaper. It's kept shipmates safe in slippery-when-wet conditions. Swimsuits modeled on shark skin are said by Speedo to reduce drag by up to 4 percent. Now, research by two separate groups could lead to synthetic shark skin that would make ships and submarines faster and less expensive to operate.
In order to test the implications of early emotional bonding, scientists have done testing on infant emotionality by separating animal babies from their natural mothers, allowing them to be raised by another of their same species. This testing strategy is called Cross fostering
- Transfer of children between mothers is known as cross-fostering. This method is used to distinguish between environmental and genetic impacts on behavior.
- Transferring some freshly born or hatched young of species A from their mother nest to the nests of species B is the primary process of cross-fostering.
- A behavior can be proven to have a genetic foundation if cross-fostered offspring have a behavioral attribute that is distinct from that of their foster parents and similar to that of their biological parents.
- Similarly, environmental variables are proven to be dominating if the offspring exhibits qualities that are different from those of their biological parents and comparable to those of their foster parents.
- There is frequently a combination of the two, demonstrating both genes.
- This can be utilized in selective livestock breeding to combine desirable genetic traits like weight, fat distribution, or looks with ones that are influenced by the environment, like temper.

Exchange of nutrients occurs in the digestive system. Exchange of oxygen occurs in lungs
Each layer contains the square of the layer number.
<span>So,
Let's figure out :
1 squared = 1 </span>
<span>2 squared = 4 </span>
<span>3 squared = 9 </span>
<span>4 squared = 16 </span>
<span>5 squared = 25
</span>6 squared = 36
<span>Hence,
The total number of oranges in the pile = 1+4+9+16+25+36
= 91 oranges
</span><span>
D. 91</span>
Answer:
they can cause a lot of harm in human body
Explanation:
based on research, a virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism.
Bacteria are a type of biological cell. They constitute a large domain of prokaryotic microorganisms.
and lots more all can do a lot of damage to the human body they can even take someone's life.
