The law of spontaneous generation states that the living forms can grow from the non-living objects. The examples of this law were believed to be the arrival of maggots on meat, and dust from the flies. This law was believed to be true for an extended period of time. During those times, the microscope was not invented, and hence, people were unaware about the existence of the living organisms that cannot be seen with the naked eyes (microorganisms). This led to the people believe in the spontaneous appearances of life forms.
Answer:
The statement, that is, the fossil record does not contain any fossil remains of plants, only animals is false.
Explanation:
Any trace of past life is termed as the fossil. It can be an organism's remains like shells, plants, bones, or teeth. Any activity of an organism like burrows, footprints, and feces can be known as a fossil record. Five different ways by which the formation of a fossil takes place are natural casts, permineralization, trace fossils, amber preserved, and preserved remains.
The formation of a fossil distinctly takes place, however, the majority of them formed when an animal or plant dies in a watery environment and gets buried underneath the silt and mud. In the process, the soft tissues quickly get decompose and leave behind the shells or hard bones. With time accumulation of sediments takes place over the top and solidifies into a rock.
Collisions between all molecules increase as temperature increases. This is due to the increase in velocity and kinetic energy that follows temperature increases. ... This results in more molecules reaching the activation energy, which increases the rate of the reactions.
Answer:
The gonads are responsible for the production of steroid hormones, such as testosterone, estrogen, and progesterone.
Explanation:
Answer:
the release of heat by the formation of hydrogen bonds.
Explanation:
Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
Condensation can be defined as a process which typically involves the change in the physical state of matter from the gaseous phase into a liquid phase i.e water changing from gas (vapor in the air) into a liquid form.
Temperature usually increase when water condenses. This phenomenon is as a result of the release of heat (exothermic reaction) by the formation of hydrogen bonds in water i.e hydrogen-hydrogen bond in water molecules formed by the chemical elements; oxygen and hydrogen.
