1.

The answer is clearly "C" because an adaptive feature is a feature in which a living organism has adapted to, for example:

Millions of years ago, fish and other water creatures evolved to breathe on the surface, and not just in the water. However, this process took many years to adapt to the climate.

2.

I know that this is a gene so I assume, by the wording that this is a length of DNA from another human. Can't particularly explain this very clearly though, sorry. You can read more about it here though by searching about it, sorry I can't put the link as my answer will be removed.

I hope this helps you but if it does not, don't be mean! Message me and I will try my hardest to resolve my answer! :D

Based on the temperature data in the table which chemical reaction should the students use for their food carrier design
Sladkaya [172]

Answer:

Reaction 1

Explanation:

Reaction 1 would be the most suitable in this case. This is so because in reference to the question you are wanting to keep the food warm over long periods. So in reference to the data in the chart reaction 1 continues to heat up over long periods of time. However, with the other reactions (2, 3, 4) temperatures vary and some even decrease constantly. Therefore showing that the other reactions are invalid to help reach your goal referencing back to the question.

Scientists observed that the populations of top-level consumers in a particular ecosystem were rapidly decreasing. Further studi
yanalaym [24]

Answer:

The correct answer is - decreased population size at all levels.

Explanation:

A decrease in the productivity of producers of an ecosystem will lead to a decrease in all other organisms of the ecosystem including top-level consumers to the bottom-level producers due to the fact that producers provide energy and food to primary consumers.

It is because they are the only organisms that convert the sunlight to usable energy and food that transfer from one trophic level to other, so if the population of producers or their productivity will decrease then there will be decreased population size at all levels.

Cardiovascular system. It regulates body temperature, fights infections, removes cell waste and it brings oxygen to cells. Its major organs are arteries, veins, heart, and blood vessels. It interacts with the digestive system to help red blood cells to carry nutrients and digested food in the body. It reacts with endocrine which helps red blood cells to carry hormones which deliver a message to the body.

Respiratory system. Its work in the body helps in breathing.Its major organs are lungs, pharynx and nose.works closely with immune, excretory system and circulatory system.

Muscular system. Helps in the circulation of foods and blood and allows it to produce voluntary movement.Its major organs are cardiac muscles, smooth and skeletal muscles.

Digestive system. It absorbs and converts food into molecules for cell use and it also helps in elimination of solid waste. Its organs are mouth, stomach, and intestines. It interacts with cardiovascular and excretory systems.

Urinary system. It helps in elimination of salt, excess water, and body waste. Its organs are bladder, urethra, urinary tract, and ureterus. It reacts with the nervous system where bladder sends sensory into the brain and then brain control urination.

Endocrine system. It maintains homeostasis and controls growth and development through hormones. Its main organs are testes, ovaries, and glands. It works closely with reproductive, digestive, nervous, and cardiovascular.
