In one of the studies of about rats in Easter Island, it was believed that rats were the reason for the decrease of palm trees.
According to a system framework study, there are relationships between the birth and death of people with the rats and the palm trees. It explains that peoples' population in Easter island has a relationship with rats and palm trees in the area.
<span>The number of palm trees decreases because of the increased number of rats that eats its fruits. Seed germination became frequently interfered because of this activity.
</span><span>However, the slow growth of palm trees was also blamed for the tree cutting off the people.</span>
Answer:
After the water soluble hormone approaches its target, the last thing that happens in change in cell activity and the hormones send a signal/message to the original hormone.
Explanation:
Water soluble hormones easily attach themselves to the cell. These water soluble hormones are made up of amino acid. Amino acid are basically proteins which are easily soluble in water.
These water soluble hormones cannot enter the cell membrane of the cell because they are made up of fat cells.
Answer:
<u>Sister chromatids are identical forms of chromatids of a chromosomes. They are mostly formed by semi-conservative replication of DNA molecule of a single chromosome.Thus they are like </u><u>'photocopies' </u><u> of original parent chromosomes; joined together at the Centromere</u>.
They are exactly similar in all ramification; with the same gene and allele compositions..
<u>However; slight differences arise between the two identical sisters due to </u><u>mutation</u><u> from</u><u> errors </u><u>at replication;and also in the length of telomere repeats.</u>
Non-sister chromatids are dissimilar forms of chromatids of a chromosomes formed when each half of a chromosome at fertilisation from separate haploid sex-cells, of each parent. fused.They contain different genetic composition;because they are not on the same homologous chromosomes.Therefore crossing -over ensure variation.
<u>However, they are genetically similar in composition; if they are contained in homologous chromosomes</u>. This is because Synapsis of bivalent of these chromosomes allow genetic material to be shared by chromosomal crossing-over between the non-sister chromatids on the chromosomes ; therefore identical genetic characteristics are shared .
Explanation:
<span>The lynx population will increase. Then the hare population will drop because they're being eaten by all the lynxes and so the lynx population will drop too because they won't have much food. These things can be modeled with differential equations.</span>
The first reason is that Thats because the seeds will remain dormant until they have the resources they need for eg: some seeds are frozen in winter so that they wont germinate until they have enough resources in spring .
