"Rainwater can replace or replenish freshwater sources" and "precipitation, such as rainwater, is a source of freshwater on Earth" statements describe freshwater sources
<u>Explanation:</u>
Rainwater a source of pure distilled water, evaporated by the sun. When it falls it comes in contact of air and land. when ground soaks the water it becomes mineral water. And it is safe for drinking.
All the freshwater sources are result of precipitation from the earth surface,in various form i.e rain,mist,snow. Freshwater falling as rain have materials dissolved from atmosphere in it,sea and the land over which the clouds has travelled.
A series of steps designed to solve problems and answer questions is "a scientific method".
Answer:
A. the two genes on chromosome 1 are more than 50 mu apart.
Explanation:
Two or more genes present on the same chromosomes are the linked genes. Linked genes do not assort independently and do not exhibit crossing over. Therefore, the linkage of genes results in deviations from Mendel's law of independent assortment. However, if the linked genes are present far from each other on the same chromosome, they may exhibit crossing over.
The greater the distance between the linked genes, the higher are the chances of crossing over. Crossing over of linked genes would result in some of the progeny to have the new gene combinations as it occurs during an independent assortment of two genes. Therefore, Mendel observed an independent assortment of two genes present together on chromosome 1 since they were present far apart from each other (more than 50 mu apart).
The post mortem interval of a body enclosed in a plastic bag could be best estimated by the insects found in the body, in that case forensic science need to listen to what those little creatures have to say, insects could tell if the body has been moved from the crime scene, how long it´s been in an specific place, and how long it´s been since death until found, every group of insects can tell something different, from worms, arachnids to flyes, each one of them has a time to get into the body, so it could tell you for how long it´s been dead.
