Answer:Transcriptional Regulation
Explanation:
Eukaryotic gene expression can be regulated during the time of transcription and RNA processing, which takes place in the nucleus of the cell and then during the time of protein translation in the cytoplasm.
Further regulation is being carried during the time of post transnational modification. The conservation of energy is very important because it saves the overall energy and space in the body.
Hence, the most important point for the regulation would be transcriptional regulation.
Answer:
The tree absorbs light energy from sunlight, converting the light energy into chemical potential energy stored in chemical bonds. The tree uses this energy to build leaves and branches and fruit. When the apple hits the ground, kinetic energy is transformed into heat energy.
Explanation:
From the pith outward, if you looked at a cross-section of a eudicot plant stem, you would see Xylem, vascular, cambium, and phloem in that order. The vascular cylinder divides the ground tissue into two discrete areas and is structured in a ring in eudicot stems.
The pith refers to the area of ground tissue that is included within the vascular cylinder. In general, eudicots possess three or more of the following traits: There are 2, 4, or 5 flower parts, or multiples of 4 or 5, and leaves have netted venation (pinnate or palmate). A ring of stem vascular bundles surrounds the pith, and seeds have two seed leaves (cotyledons).
As a result, we can assert that if you cut a cross-section of a eudicot plant stem, Xylem, vascular, cambium, and phloem in that order, you will find various plant tissues from the pith outward.

Answer:
The reason that there is no fruit even the plant produced healthy flowers maybe because
1. absences of pollinators due to declining poliinator population
2.weather conditions are preventing pollination
3. prevalence of flooding
Explanation:
1.Fruits are direct result of pollination. Due to the decrease in the number of pollinators especially orchid bees, some fruit bearing plants produce flowers but no fruit.
Bees decline their population because of parasites, diseases, exposure to chemicals and other environmental factors.
2.Unfavorable factors may prevent the agents of pollination to do their jobs. Bees and other insects may be hindered by wet or cold weather or some use of chemicals.
3.Brazil nut grow in lowland rainforest where there is no flooding.
