Darwin’s theory suggests that there is some evolutionary advantage towards beetles because they can use camouflage as a defense strategy against predators.
Answer:
While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis (Figure below) and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
The nucleus is so designed with a bilayered nuclear membrane to store/ house DNA . DNA is an important part of eukaryotic cells as it is the gene from this DNA that will code for protein to be produced in the cell and it is this said DNA that house the unit of inheritance of the cell (gene)
<span>B. Oxygen-rich blood is carried in the aorta from the left ventricle to the body.
</span>Superior and inferior vena cava enters the right atrium which is pumped by the tricuspid valve to the right ventricle and to the pulmonary valve to the pulmonary artery then to the lungs from the lungs back thru the pulmonary veins entering the left atrium pumped by the mitral valve to the left ventricle to the aortic valve to the aorta.
<span>The circulatory system is important in meeting the needs of all cells in the body because it offers means of transport by which cells obtain the materials needed to live and function.</span>
