Answer:
#1 false its difficult but also possible. #2 true and #3 False. the Salivary gland in the mouth make 1.5 liters a day
Explanation:
However, in 2016 researchers published a new set of Neanderthal DNA sequences from Altai Cave in Siberia, as well as from Spain and Croatia, that show evidence of human-Neanderthal interbreeding as far back as 100,000 years ago farther back than many previous estimates of humans' migration out of Africa (Kuhlwilm Dec 11, 2020
Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.
The answer is RESPIRATION
1. An example of secondary consumer is snake. Secondary consumers are the ones who eat the primary consumers, which makes them carnivore.
2. Photosynthesis is a process used by plants and (some other organisms) that converts water (H2O) and carbon dioxide (CO2) with the presence of sun energy (collected in the chloroplasts) into chemical energy that is later stored in sugars (carbohydrates). Organisms that do the photosynthesis are called autotrophs (produce food by themselves).
3. The energy pyramid represents energy flow in a community, where the different levels represent different groups of organisms.
The food chain is a circulation of energy that comes from the sun and passes from the producer organisms to the primary consumer, secondary and tertiary consumer organisms.
4. For example, plant is producer that is eaten by primary consumer-herbivore (e.g. bugs). Than secondary consumer-carnivore (e.g. snake) eat that herbivore and than is being eaten by tertiary consumer (apex predator that have no natural predator).
5. One trophic level gets only 10% of the energy of the previous level. So, if the plant have 10.000 units of energy and is eaten by rabbit, rabbit gets 1000 units of energy, and when the fox eats an rabbit, it gets 100 units of energy.
6. Trophic level is the position of an organism in the food chain.
Answer:
The nervous system has two main parts:
The central nervous system is made up of the brain and spinal cord.
The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
hope it helps :)
