The correct option is A.
Environmental DNA surveillance is used for detection and monitoring of invasive animal species in aquatic and terrestrial ecosystem. The surveillance method provides information for the management personnel about the existence of alien species or outbreak of diseases. Early detection is always crucial in this case in order to prevent fatal consequences.<span />
The answer is high. It is because bipolar disorder does
cause high rate of heritability because of factors that could affect the
individual. These factors or biological cause can affect greatly in which is
why it has been concluded that it could cause high heritability. The factors have been a great contribution in making an individual to be susceptible or acquire this type of disorder.

Hey again,
The answer you are looking for is B).
Just as proteins consist of long chains of amino acids, DNA and RNA consists of nucleic acid chains called nucleotide's. Nucleotide's are composed of three units: base, sugar (monosaccharide) and phosphate. Bases are found in both DNA and RNA. As seen below, they are adenine, cytosine, guanine, thymine, and uracil.
Hope this helps!!!!!!

Weathering is the process by which rocks are broken down into smaller particles as a result of physical and chemical changes that are occurring in them. There are three major types of weathering these are: physical, chemical and biological weathering.
For the question given above, the type of weathering that is occurring in the picture of the given rock is PHYSICAL WEATHERING.
Physical weathering is the type of weathering in which the affected rock is changed in size and shape by means of some agents. The broken particles are usually of the same composition as the parent rock. The agents of physical weathering include: ice, plant roots, animal activities, abrasion and exfoliation. Physically weathered rocks are usually round in shape as a result of the abrasion process which they have undergone.<span />
Answer:
Earliest- gametophyte dominance, sporophyte dependence
Middle- sporophyte dominance, gametophyte independence
Recent- sporophyte dominance, gametophyte dependence
Explanation:
The life cycle of plant alternates between the two phases: the haploid gametophyte which produces gametes and the diploid sporophyte which produces spores. The evolution of land plants shows how these are dependent on each other in terms of the requirement of nutrition.
In bryophytes, the gametophyte is the dominant phase on which the sporophyte depended. Later in pteridophytes, the sporophyte became dominant which is present in the later evolved groups namely the gymnosperms and the angiosperms. The gametophyte was independent on the sporophyte but in angiosperms and gymnosperms, it is dependent.
