Plants reproduce through the
process of fertilisation. Fertilisation is the process where female and male
cells join together to form an embryo inside the seed. The seed protects the
embryo in preparation for germination when conditions permit the plant to
produce new plants.
Seed plants are classified into
two types to determine reproduction. First are the Angiosperms, this type of
seed plant has flowers that have special structures for reproduction. Pollens
are made by male cells, while ovules are made by female cells. Pollens are carried
out through the process of pollination (e.g. wind blows, insects carrying
pollen). Most angiosperms that don’t undergo pollination develop intro fruits.
If it goes into pollination they become new flowering plants.

Second classification is the
Gymnosperms, which are seed plants that are held in cones. Gymnosperms like
Angiosperms also have male and female reproductive cells. Reproduction also
occurs through pollination but most gymnosperms are trees. The best example of
a gymnosperm are pine cones. </span>
first step
A copy is made of one side of the DNA segment where a particular gene is located. This copy is transferred to the cytoplasm.
second step?
This mirror like copy of a DNA segment is called messenger RNA (mRNA)
third step?
Each group of three bases on the mRNA segment codes for one amino acid.
fourth step?
The mRNA segment is fed through the ribosome.
fifth step?
Molecules of transfer RNA (tRNA) deliver amino acids from the cytoplasm to the ribosome.
sixth step?
The amino acids are dropped off at the ribosome.
seventh step?
The amino acids are joined to make a protein. Usually, one protein is produced for each gene.
A reasonable conclusion supported by these observations is that the animal was endothermic and had a high metabolic rate.
<u>Explanation:</u>
With reference to warm-blooded species is preferred the endothermic are the species that preserve a steady body temperature regardless of the ambient temperature. Endothermic species mainly include animal kingdom birds and mammals. Many shrimp, however are endothermic too.
If a variation occurs, i.e. if the heat produced is less than the heat loss, the metabolic rate increases to compensate for that loss. Shivering is another method used by people and many other warm-blooded organisms to boost their body temperature. But in case the heat loss is smaller than the heat produced, the process of panting or suddening occurs to increase the heat loss.
