Answer:
It helps to ascertain the number of living beings on earth.
Explanation:
More than one million of species of plants and animals have been discovered and classified so far. It aims to classify the living organisms. Millions of organisms are classified scientifically in categories, which helps to have a better understanding.
The appropriate response is active transport. Active transport is the development of particles over a cell layer from a district of their lower focus to a locale of their higher fixation—toward some inclination or another deterring factor.
Active transport utilizes cell vitality to move them against an angle, polar repugnance, or other resistance.
Answer:
Cost: competition for mates, competition for resources
Benefit: better protection from predators (ex. a fish in a school of fish has greater chances of not getting eaten because of the large number of other fish)
The correct answer is D. It is characterized by coniferous trees.
Answer:
Light-dependent reaction of the photosynthesis takes place in the thyllakoid membrane of the chloroplast. It converts solar energy into the chemical energy (ATP and NADPH) which is then utilized in the light-independent reaction to fix carbon into glucose or food.
The correct order of events that take place during light-dependent reaction would be:
Energy from the Sun ejects electrons from chlorophyll and splits water molecules to yield hydrogen ions.
↓
Electrons move down the electron transport chain, releasing energy that pumps hydrogen ions into the thylakoid space.
↓
The concentration of hydrogen ions in the thylakoid space increases.
↓
Hydrogen ions diffuse across the thylakoid membrane into the stroma through ATP synthase.
↓
ATP synthase uses the energy released as hydrogen ions move from regions of high concentration to regions of low concentration to make ATP.
