Answer:
Water has the property of cohesion and adhesion. Cohesion provides the property of water to get attached with other water molecules and it holds water molecules together, adherence provides the property of stickiness to any surface to the water molecule.
These two properties together allow water molecules to move upwards against gravity. Water moves by capillary action through the water column. Cohesion and adhesion create a pull on the column which transport the water towards the leaves from where they get evaporated.
This evaporation then causes tension on another water molecule and this tension then pulls another water molecule towards leaves.
suppose P is a dominant allele for a flower color and p is a recessive one.
The expected ratio of genotypes among the F1 offspring is 1 Pp : 1 pp.
The white pea bloom was "masked" in the F1 generation, which caused all of the flowers to be purple.
The "masked" genes from the F1 generation were permitted to mate, but they were only allowed to pair once, leaving the other three times to appear with purple flowers, resulting in a 3:1 ratio of purple to white blooms in generation F2.
He paired a homozygous dominant flower with a homozygous recessive flower in his initial attempt. As a result, all of the F1 generation's progeny were heterozygous, making them all purple.
Two heterozygous, one homozygous recessive, one homozygous dominant, and the progeny of the F1 generation were crossed with another heterozygous plant.

Here is the complete statement:
The black footed ferret specie can be saved by the ENDANGERED SPECIES ACT. The US FISH AND WILDLIFE SERVICES will manage the Act.
EXPLANATION:
An endangered specie refers to an animal or plant species, whose population has become very low and is in danger of becoming extinct in the nearest future. In the United States of America, such plants and animals are usually managed by the Us Fish and Wildlife services. This is a federal agency that is responsible for the management of different forms of wildlife, fish and natural habitats within the US.
The Endangered Specie Act is a US law that makes provisions for the management of both plants and species, which are deem to be on the verge of becoming extinct. The law makes provisions for the conservation of endangered living organisms and their natural habitats. The endangered specie Act prohibits the hunting or killing of endangered species; acting contrary to this law usually carry severe penalties.
Answer:
scientists got the space station up in space in to small pieces.
Explanation:
The main problem which was faced by the scientist was that there was no powerful rocket which has the ability to lift the whole space station due to its more weight and carry it to the space against the powerful force of gravity. So for solving this problem, space station is taken into pieces into the space and then these pieces should be join to build the space station.
Answer:
The purpose of the Miller and Urey experiment was to see if organic compounds that could sustain life be created spontaneously in Earth's early atmosphere. They wanted to see if complex molecules of life (eg. Amino acids, etc.) could be created using natural chemical reactions when Earth had harsh conditions.
