What do we call the cells in phloem that are alive at maturity but lose almost all their organelles?
A. Sieve- tube
B. Tracheid's
Answer:
Sieve-tube
Explanation:
Sieve elements are thin-walled cells that are alive at maturity, although the protoplast is greatly changed, and they generally lack nuclei. Sieve elements are elongated and function as the basic photosynthate-conducting cell type in the phloem of vascular plants.

The relationship between the amount of energy available for use and the amount of entropy in a food chain differs between trophic levels. why would the amount of entropy increase from one trophic level to another in a food chain or energy pyramid? a. the available energy from one trophic level to another increases b. energy is lost at each level as heat, which increases randomization c. the amount of biomass decreases from one trophic level to another d. the available energy at each level may either increase or decrease, creating randomization please select the best answer from the choices provided a b c d
The energy in the pyramid is entropy as it helps in the energy transfer energy from the trophic level the correct option is energy is misplaced at every tropic stage as warmness and serves to growth entropy.
The strength glide via meals chain and meals webs comply with the second regulation of thermodynamics. At every tropic stage, the handiest 10% strength is surpassed in the following stage and relaxation 90% is misplaced as warmness. Therefore, strength switch via meals chains continually finally ends up with lesser usable strength. The strength misplaced in the surroundings in the shape of warmth has a tendency to grow the entropy of the system. The better the tropic stage, the greater the warmth to be had to growth entropy.What is an energy pyramid?
A strength pyramid additionally called atrophic or ecological pyramid is a graphical illustration of the strength located in the trophic degrees of an ecosystem. The backside and biggest stage of the pyramid is the manufacturers and includes the biggest quantity of strength.
Thus it is clear that energy is lost at each level as heat, which increases randomization.

As you move from right to left on the periodic table, what happens to the number of protons and neutrons in atoms?
As you move across a period, the atomic mass increases because the atomic number also increases. When the atomic number increases, this means that there are more protons and neutrons that add to the atomic mass of an atom. The atomic mass for any given atom mainly comes from the mass of the protons and neutrons

Which aspect is an example of structural adaptation?
The bill lengths of carnivores are an example of a structural adaptation. Therefore, option (4) is correct.
Structural adaptations are physical features or characteristics of an organism that have evolved to help them survive and thrive in their environment. In this case, the bill lengths of carnivores (meat-eating animals) have evolved to suit their specific feeding habits and prey types.
For example, some carnivores have long, sharp bills for tearing apart their prey, while others may have shorter, more robust bills for crushing shells or consuming insects. The specific bill length is a structural adaptation that aids in obtaining and consuming food efficiently, which is crucial for the carnivore's survival and reproductive success in its ecological niche. Therefore, option (4) is correct.
