Which term best describes the change from more light-colored moths to more dark-colored moth:

maria [59]

Answer:

The correct option is B) adaptation

Explanation:

The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.

Answer:

Explanation:

The number of protons in atom is the atomic number. For a neutral atom that has not lost or gained any electron, it is the same as the number of electrons.

The atomic number is used in perfect ordering of the periodic table and it is the basis of the periodic law.

Which of the following abiotic factors might have an effect on how much photosynthesis can occur by the producers in an ecosyste

Evgesh-ka [11]

Abiotic factors such as temperature, water quality, air quality, soil quality, and sunlight efficiency affect the rate of photosynthesis. Thus, the correct option is D, i.e. All of the above can affect photosynthesis.

<h3>What is Photosynthesis?</h3>

Photosynthesis may be defined as a process through which green plants synthesized their own food (glucose) via carbon dioxide and water in the presence of sunlight.

The rate of photosynthesis primarily depends on the numerous abiotic factors which are present in a particular environment.

For example, Desert plants accomplish photosynthesis by the CAM pathway, which requires less water as compared to rainforest plants.

The maximum rate of photosynthesis occurs in the region of photosynthetically active radiation (PAR), which belongs to the wavelength of 400nm-700nm.

Therefore, it is well described above.
