Explanation:
It's a soft metal, reactive and with a low melting point, with a relative density of 0,97 at 20ºC (68ºF).
Answer: False
Explanation:
The patellar tendon attaches the bottom of the kneecap (patella) to the top of the shinbone (tibia). It is actually a ligament that connects to two different bones, the patella and the tibia.The patella is attached to the quadriceps muscles by the quadriceps tendon.The medial and lateral vasti muscles also attach independently to patella to form aponeuroses, the medial and lateral patellar ligament. Working together, the quadriceps muscles, quadriceps tendon and patellar tendon straighten the knee. When the patellor tendon is ruptured, the ability to extend the knee is greatly effected and decreased but its not completely disappears. Thus the quadriceps functions is not entirely compromised.
Probaly abiotic would be the most likely answer in my opinion.
Answer:
Diatoms
Explanation:
Diatoms are a photosynthetic eukaryotic phytoplankton that virtually found in all waterways, fresh waters and oceans, and also in most soils on earth. Diatoms play a very important role in the global carbon cycle. Diatoms are single-celled algae that has a characteristics cell wall that is made up of transparent opaline silicia that are elegantly sculpted.
When diatoms die, their shell or skeleton that is composed of silica, do not decay, but settle at the bottom of oceans as sediments to form what is often referred to as diatomaceous earth. It is this diatomaceous earth deposit that is then converted to diatomite powder, which is used as pesticides against insects such as ants, cockroaches, bedbugs and some other pests.
The correct answer is:
Explanation:
Through the actions of decomposers, phosphorus and sulfur are reacted to the soil. Decomposers are organisms that break down stagnant or decaying organisms, and in doing so, they bring out the natural process of dissolution. Their energy is earned by the use of organic substrates.
