Leni [432]3 years ago
5 0

Explanation:

Root hairs are found in the plant it is a hair-like structure present on the surface of the root tip and Root hairs have large surface area that increase the absorption rate of water and minerals.

Water is absorbed by root hair cells through the process called Osmosis and Minerals ions is  absorbed  root hairs by the process called active transport.

The function of root hair is to collect the minerals and waters present in the soil and then transfer these nutrients and water through roots to different parts of the plant.

grandymaker [24]
I know that the environment plays a role in the changing of hair or feathers in some animals so here: 

Winter- color changes to more resemble winter surroundings. You'll see more white colors to blend in. 

Summer- the colors more resemble the summer colors; you'll see more browns and rocky looking colors to hide/blend in. 

Spring- you'll see very vibrant colors like that of a flower.

Those are some examples, but I hope this helps.

Jet001 [13]

Answer:

Using beta-hydroxy-beta methylbutyric acid (HMB) can improve performance for those who perform explosive repetitions of activity, such as running or lifting weights. Consuming small amounts of caffeine can increase mint alertness. C. The consumption of branched-chain amino acids and creatine can improve muscle recovery after intense physical activity. D. An ergogenic aid that increases muscle mass but can also cause uncontrolled growth of the heart or other organs and is prohibited by the International Olympic Committee: anabolic steroids.

Explanation:

In the answer I leave you the text with the blanks completed ... It is also important that you know that amino acids are important for the formation of muscle mass and its recovery, in addition to creatinine.

On the other hand, these supplements are administered in people who have high performance in sports, and accompanied by a good diet and specific diet, otherwise they will not work.

Anabolics are chemical structures that promote energy reserves and anabolism for muscle tissue hypertrophy, but they do not have a selective effect on the skeletal muscle, but rather affect other parts of the body, that is why they are risky, cause heart failure, cardiovascular, liver, kidney, and even possible alterations of the gallbladder.

Answer:

The law of conservation of mass

Explanation:

The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
