The correct answer is option C, that is, physical weathering.
The weathering resulting due to the influences of changing temperatures on a rock, making the rock to split apart is known as physical weathering. There are two main kinds of physical weathering, that is, exfoliation and freeze-thaw.
Physical weathering takes place mainly in the locations, where few plants grow and little formation of soil occurs, like hot deserts and mountain regions. It takes place either via repeated freezing and melting of water or via contraction and expansion of the rocks surface layer, which is baked by the sun.
Yes, while multicellular organisms remove waste through the urinary system, single celled organisms expel their metabolic waste with vacuoles
Answer:
Limited food supply and competition
Explanation:
Density dependent factors are those which in general lead to reduction of growth rate of population when the population density increases. One of such factor is availability of food and competition.
Whenever the density increased to an extent where the resources or available food becomes scarce or limited,then the growth rate of population decrease. These factors generally lead to logistic growth pattern of population.
Bond covalent. monomers are joined together by a dehydration reaction in which two molecules are covalently bonded to each other through the loss of a water molecule
The answer is chlorophyll a.
Chlorophyll a is the only light-absorbing pigment in reaction centers.
