Answer:
we need to focus on the 10 main threats to soil functions: soil erosion, soil organic carbon loss, nutrient imbalance, soil acidification, soil contamination, waterlogging, soil compaction, soil sealing, salinization and loss of soil biodiversity.

Answer: Species A is diploid, it means 2n=36, the haploid number is 36/2=18. Species B is triploid, it means 3n=36, then the haploid number is 36/3=12.
Explanation:
A chromosome is an ordered bundle of DNA associated with proteins such as histones, and it is found in the nucleus of the cell. Different organisms have different numbers of chromosomes. Humans, for example, have 23 pairs of chromosomes, 22 of them are autosomal pairs, and one pair are sex chromosomes, which indicates the sex of a person. Each parent contributes one chromosome from his or her autosomal pair and one from the sex pair, so that the offspring get half of their chromosomes from their mother and half from their father.
<u>A haploid cell has only one set of chromosomes (n), whereas diploid cells have two sets of chromosomes (2n) and triploid cells have three sets (3n). In the example of humans, a diploid cell is a somatic cell and has 46 chromosomes (or 23 pairs). And a haploid cell, a gamete for example, has 23 chromosomes. </u>
If two species of plants carry 36 chromosomes, and species A is diploid, it means 2n=36. Then the haploid number is 36/2=18. Species B is triploid, it means 3n=36. Then the haploid number is 36/3=12.
The maximum number of atoms that a hydrogen atom can bond with is <em>one.</em>
The ends of the actin filaments are anchored to the Z-line or disk.
The sarcomere is the primary functional unit of muscle fiber. It is flanked by a Z-band on each end with adjoining I-bands. The Z-band or disk is a dense fibrous structure composed of actin, α-actinin as well as other proteins.
Thin filaments or actin filaments are anchored at one end at the Z-band. Titin is connected to both the Z-band and the M-line. Thick filaments are attached in the middle of the sarcomere at the M-line.
An intermediary filament protein forms a meshwork from one Z-disk to the next across the myofibril. These networks are joined by actin through the protein dystrophin to the sarcolemma.
