Answer:
Describes the role of monitoring in adaptive management. ... each vegetation attribute and advice on field techniques and tools are provided. ... If you are using sampling to estimate population sizes or mean values (such as density, ... obtain the true average number of plants per quadrat (4 plants/quadrat).
Explanation:
Quadrat method is the most widely used method for population determination in plants and small immobile organisms.
What are the methods for population determination?The Quadrat method is the most useful method for population determination for immobile organisms such as plants or for very small and slow-moving organisms. The plots used in this method is called quadrats, which may be used to determine the population size and density of a population. Here, each quadrat marks off an area of the same size which is typically, a square area or other shape such as circular or other within the given habitat.
The most accurate way to estimate the weed population is to count the number of plants in an area of known size at a different number of locations. Through the use of a quadrant, which may be square or circular in shape weed plant counts can be carried out.

Y: Parasitism
Rationale: in parasitism, one organism suffers while the other benefits in the relationship.
The fleas on warm-blooded animals is the organism that benefits solely from the association while the animals suffer.

A cell from a tissue culture has 38 chromoses after mitosis and cytokinesis one daughter cell has 37 what might occurred to cause the abnormal chromosome number
Answers
Answer:
occurred an aneuploidy (monosomy)
Explanation:
Aneuploidy can be defined as a chromosomal aberration in which the chromosome number is abnormal. In an aneuploidy, the number of total chromosomes in daughter cells is not an exact multiple of a haploid set, by either gaining or losing chromosomes during mitosis. Aneuploidies are common in cancer cells and in different types of chromosome disorders. Moreover, monosomy is a type of aneuploidy in which daughter cells have a single chromosome copy instead of the two copies found in diploid cells. For example, Turner syndrome is a monosomy caused by the loss of the X chromosome.

A woman with blood type a (whose parents both had AB blood) mates with a man with blood type B (his mother was AB and the father was O blood). Show the cross and the genotype and phenotype ratios of the potential offspring.
Answers
Answer:
1 AB:1 A
Explanation:
Ia Ia
Ib IaIb IaIb
i Iai Iai
i represents type O blood which is always recessive
the capital I represents co-dominant traits (a or b)
Iai is type A because O is recessive and will be masked by Ia
IaIb is type AB because both capital I traits will be codominant
This cross ultimately gives a 1:1 ratio of type A to type AB
