What happens to the population density and competition if the birth rate decreases?
The birth rate would increase is the population density competition increased.
Hope I helped.
A community is diverse species living together
An Ecosystem is all the living and nonliving factors that affect an organism
The labeled anatomical features of the muscle filament are attached as an image.
Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.
- It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
- Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)
- Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.
- A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.
Thus, the correct labeled anatomical features of the muscle filament is attached as an image.

Answer:Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
