Answer:
Physical changes can easily be reversed but chemical changes cannot because in physical change only state is changed while in chemical change, new substances are formed. For example, when water in liquid form is condensed, it changes into solid form (ice). It is a physical change because water in liquid and solid have the same chemical formula only arrangement of molecules are different. Burning of wood is a chemical change because new substances i. e. carbondioxide and heat is produced.
Answer;
The human eye contains more rods than cones photoreceptors.
Explanation;
-The retina of the human eye is the back part of the eye that contains the cells that respond to light. These specialized cells are called photoreceptors. There are 2 types of photoreceptors in the retina: rods and cones.
-The rods are most sensitive to light and dark changes, shape and movement and contain only one type of light-sensitive pigment. Rods are more numerous than cones in the periphery of the retina. The cones are not as sensitive to light as the rods. However, cones are most sensitive to one of three different colors (green, red or blue).
Answer:
C
Explanation:
Interphase is the uniform phase for all cells division'. It signifies the begin of any cell cycle division. it is the period of prolong rest by the cells to prepare for the long journey of cell division. It involved replication of DNA, of organelles to be distributed in the daughter cells, accumulation of food resources .,
It is made up of the G1, for normal growth of cells and function of cells, doubling of organelles numbers.
S=synthesis stage, for DNA and genetic material replications
and the G2 phase growth resumption and preparation of cells division.
Therefore since all cells must undergo Interphase and carry out all the above processes prior to cell division, this stage(interphase) must be uniform to all cells.
Animals that reproduce by laying eggs are called oviparous animals. In these animals, the process of both fertilization and embryo development does not occur inside the mother. Birds and frogs are examples of oviparous animals.
A tsunami can send a wave in multiple directions. Over time a wave will not have as much energy as did when the wave was first started. So when the tsunami hits land it will not be as strong as another wave generated from that same earthquake. EX: When the tsunami hit Japan it knocked over buildings, meanwhile America was hit with a wave from the same earthquake. However the damage was much less.
