Why do you think social insects are among the creatures that use pheromones?
Answer:
Explanation:
Social insects use pheromones to send messages to other members of their colonies. Ants leave pheromone trails that lead other ants to food sources. Certain species of honey bees release pheromones when they are injured or attacked to signal other members of the hive that there is danger, or that the hive is under attack.

How does humans affect the moth population?
How does the moth population be affected?
Answer:
Before the industrial revolution, there wasn't much pollution/soot, and the moths were mostly light colored. When humans started using machines for everything, soot coated the trees and the light colored moths were easier for birds (predators) to see. The moths became mostly dark colored, because it was better camoflauge.
Now that we have environmental restrictions, there isn't as much soot everywhere. Now moths are mostly light colored again, because the dark moths are easier to see.

The perimeter of a triangle is 240 cm.The lenghts of the sides are in the ratio 3:4:5.calculate the lenghts of the longest and shortest sides
Answer:
Longest : 100 , Shortest : 60
Explanation:
Step by step to answer :
Take 3+4+5 = 12
240/12 = 20
20 x 5 = 100 (Longest )
20 x 3 = 60 (Shortest )
20 x 4 = 80
100 + 60 + 80 = 240 correct

Which of the following statements incorrectly describes nonspecific external immune responses?
A) The skin is a physical barrier and keeps pathogens from entering the body.
B) Nonspecific external immune responses are the second immune response against pathogens.
C) All of the statements correctly describe nonspecific external immune responses.
D) Mucus is a mechanical barrier where enzymes are used to kill pathogens.
Non-specific external immune responses are the first immune response against pathogens. Thus, the given statement B is incorrect.
The immune response elicited by external parts of the body are non-specific in action. These constitute the first line of defense. These include skin, tears, mucus, sebum, nasal hair, eyelashes, etc.
The skin is a mechanical barrier that prevents the entry of pathogens into the body. The skin secretes sebum which has a pH in the range of 3-5 which inhibits the growth of microorganisms.
The mucus entraps microorganisms and thus prevents them from entering inside the body. It also secretes lysozyme, which is a hydrolytic enzyme that kills the foreign invading pathogen.

Answer:
Q5: Vestigal Structures
Q8: Enviorment
Explanation:
Q5:
Vestigial structures can provide insights into an organism's ancestry. For instance, the tiny vestigial leg bones found in some snakes reflect that snakes had a four-legged ancestor. The small leg-like structures of some snakes species, like the Boa constrictor, are vestigial structures.
Q8:Birds' beaks are the tools they have to use to gather food. The best adapted (fittest) to the available food have the best chance of surviving (not starving to death) and of having descendants. The different variations in these beak forms are each an experiment in natural selection.
Answer:
Vestigial structuresVariationsVestigial structures are structures that have a good function in the past, but are now no longer used. Let's say I have an unknown type of leg, then that leg in the future generation of my family no longer has that leg or it's changed. This is caused by variation and genetic changes, which we discuss right now.
In natural selection, variations are what likely causes beaks to vary. Variations are similar to a new thing, generation, or type of something. Like I have a lamp shade are there are tons of the same brand with different colors, that is a variation of one thing.

4. In gel electrophoresis, are the dna fragments attracted to, or repelled from the negative pole of the electric field?
In the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.
What do you mean by Gel electrophoresis?Gel electrophoresis may be defined as a technique that separates DNA, RNA, and proteins on the basis of their molecular weight.
As we all know, DNA fragments are negatively charged in nature, and hence they always move towards the positive pole of the electric field.
Therefore, in the gel electrophoresis, the DNA fragments are repelled from the negative pole of the electric field.

Organ systems of the human body interact to maintain a balanced internal environment. As blood flows through certain organs of the body, the composition of the blood changes because of interactions with those organs. State one change in the composition of the blood as it flows through the respiratory system.
The organ system interacts with each other to maintain the normal functioning of the body. The composition of blood changes due to this interaction. The change is the blood going out from the lungs is deoxygenated and the one coming to the lungs is oxygenated.
What is the interaction of the respiratory and circulatory systems?The respiratory system involves inhalation of oxygen and using this to release energy and exhalation of carbon dioxide.
The circulatory system is comprised of the heart and blood vessels. The heart pumps blood to different body organs through these blood vessels.
The transfer of oxygen is done with the help of blood. During this transfer, the composition of blood changes from being oxygenated means having oxygen to deoxygenated means having carbon dioxide.
Thus, in this way, the interaction changes the composition of blood.
