Answer: Autocrine signal, paracrine signal and endocrine signal.
Explanation:
Testosterone is an example of hormone which shows its effect on different locations of the cells.
The autocrine signal can be defined as the siganals which shows its effect on the cell from where it is being produced. This means a cell targets itself.
Then comes the paracrine signals in which signals acts locally on the cells nearby it. The cells close together to the cells producing chemical signals is being affected.
The endocrine signals can be defined as the effect of the hormone on the distant cells. The signals is produced by the cells somewhere else but is carried through the bloodstream to the distant cells.
All of the three effects is being shown by testosterone autocrine, endocrine and paracrine.
Chloroplasts are organelles within plant cells that contain chlorophyll and are responsible for carrying out photosynthesis. This process which is utilised by plants to manufacture food, requires carbon dioxide and water which is then converted into glucose and oxygen. Therefore, the release of oxygen tells us that photosynthesis is occurring inside the chloroplast.
The vascular cambium produces secondary phloem and xylem tissue.
<span>Vascular cambium, a plant tissue located between the xylem and the phloem in
the stem of a vascular plant. It is also the source of both secondary xylem growth
and the secondary phloem growth. Vascular
cambium is usually found on dicots and gymnosperms not on monocots which
usually lack secondary growth. It does not transport water, dissolved food or
minerals by plants. </span>
<span>Vascular cambia are cylinders of unspecialized meristem cells which
divide to make new cells which
specialize to form secondary vascular tissues.</span>
The answer is Because they are able to adapt to different conditions.
The least specialized animals are those animals that can survive in a wide range of different environmental factors, unlike specialized animals which are very sensitive to changes. If environment changes suddenly and drastically, highly-specialized animals could not survive because those changes are beyond a range of different factors that affects them. The least specialized animals could adapt to different conditions. For example, one species (specialized) lives in a temperature of 20-25°C. The other species (the least specialized) lives in a range of temperature 5-50°C.
If temperature changes drastically from 22°C to 10°C, the specialized species could not survive and the least specialized would just adapt to those conditions.
