Answer:
chloroplast: makes food for plant cells, photosynthesis
mitochondria:produces energy the cell needs to carry out its functions; release energy
vacuole: stores food, water, and waste
lysosome: found mainly in animal cells, digests old cell parts
endoplasmic reticulum: carries proteins and other materials from one part of the cell to the other
cytoplasm: gel -like fluid where the organelles are found
nucleolus: makes ribosomes, center of the nucleus
ribosome: makes proteins
cell membrane:controls
Explanation:
I'm pretty sure the answer is D based on the info above,and because its the only one that has the correct information about the cell parts
hope its correct
<span> C - nitrogen fixation, ammonification and nitrification </span>
I think the answer is D. A good indicator is the resting heart rate. Exercise strengthen your heart and it makes it more efficient. The resting heart rate shows of the heart is pumping blood normally each time it contracts. Having a normal resting heart rate would mean a healthy heart.
Answer:Increase in ambient global temperatures.
Recyling energy to be used again
Regulation of oxygen and carbon dioxide levels
An increase of erosion and siltation along waterways
Explanation:
Conservational biologists think about the preservation of ecosystem by maintaining the environment in a human control way.
Increase in ambient global temperatures.: The humans must prevent the increase in global temperature worldwide by preventing the rise of greenhouse gases which can lead to global warming worldwide.
Recyling energy to be used again: The sources of energy like wood, waste water can be recycled again for reutilization.
Regulation of oxygen and carbon dioxide levels.: The oxygen and carbon dioxide levels must be regulated. As oxygen is the basic requirement for respiration. The increase in carbon dioxide levels due to human activities is likely to cause respiratory diseases and health hazards in living beings.
An increase of erosion and siltation along waterways.: The erosion and siltation will likely to deposit nutrients and debris which may either contaminate the waterway or may cause eutrophication.
Answer: True.
Spleen framework is created by reticular fibres from reticular cells.
Explanation:
Spleen is an organ found mostly in vertebrates. It develop from mesenchymal cells within the dorsal of mesogastrium near the greater curvature stomach. The mesencymal cells then divide and differentied to form framework of connective tissues of spleen. The framework of spleen is created by reticular fibres of the reticular cells. Reticular fibres are fibres in the connective tissue that is composed of type iii collagen secreted by reticular cells. Spleen function in filtering of blood. It plays a major role in red blood cells and immune system.
