I think you b and c is the other way around.
Regardless, the answer is Two elephants
The air pressure on your body is about 10kg same as the weight of 2 elephants
It was plants. Plants used photosynthesis, basically the sun's energy. And other animals ate the plants, and other animals ate the animals that ate the plant.
Producers:
One example of producers found in food chains include plants. They use photosynthesis to make their own food. Examples of plants include trees, grass, moss, flowers, and weeds, to name a few.
Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).
Types of Secondary Consumers
Spiders, snakes, and seals are all examples of carnivorous secondary consumers. Omnivores are the other type of secondary consumer. They eat both plant and animal materials for energy. Bears and skunks are examples of omnivorous secondary consumers that both hunt prey and eat plants.
In the real world, a tertiary consumer can eat many different animals and even plants sometimes. This means that they can actually be carnivorous or omnivorous. Some examples of tertiary consumers include, birds of prey, big cats, and foxes.
Answer:
he summer of 2001–2002 saw a mass bleaching event that was slightly more severe than the 1997–1998 event. The first signs of substantial bleaching were reported in January 2002, with the worst over by April.
In response, GBRMPA implemented the world's most comprehensive survey of coral bleaching in collaboration with AIMS, the Cooperative Research Centre for the Great Barrier Reef (CRC Reef) and the US National Oceanic and Atmospheric Administration (NOAA). Aerial surveys revealed bleaching in 54 per cent of the 641 reefs observed. Nearly 41 per cent of offshore and 72 per cent of inshore reefs had moderate or high levels of bleaching.
Again, reef recovery was generally good, with fewer than five per cent of the reefs suffering high mortality. The worst affected reefs were in the Bowen area where around 70 per cent of corals died.
Explanation:

Answer:</h2>
<u>A. Crossing-over between homologues.</u>
<h2>
Explanation:</h2>
In meiosis and mitosis, recombination happens between comparable particles of DNA (homologous groupings). In meiosis, non-sister homologous chromosomes pair with each other so recombination ordinarily occurs between non-sister homologs.
All living organism reproduces either through asexual reproduction or sexual reproduction or sometimes through both mode of reproduction. In both cases let it be sexual or asexual, the mode of cell division namely meiotic and mitotic cell division, the recombination between homologous chromosomes is a typical system utilized in reproduction.
