Energy in most ecosystems must flow through autotrophs because only autotrophs can convert solar energy in chemical energy.
Explanation:
This suggests that these are organisms which are entirely based on the Greek name self-producers that can produce complex organic materials by fixing together simple building blocks in their local situation. E.g plants on land. Photosynthesis in plants transforms solar energy into chemical energy using electrons and protons from water. The method of photosynthesis in plants involves a series of steps and reactions that use solar energy, water, and carbon dioxide to produce organic aggregates and oxygen.
When theres no oxygen
Answer:
Gypsum and limestone.
Explanation:
Mining of valuable stones such as gypsum and limestone occur in my location. These valuable stones are used in the formation of beautiful tiles and in painting materials. Due to extraction of these valuable stones, erosion of the land occur as well as air pollution increases by the use of machines for extracting these minerals so it caused adverse affect on the environment so this mining has to be limited in order to both save the environment and get benefits from these minerals
Answer:
(Answers may vary.)I live in Utah. Copper is mined in my state. Bingham Canyon Mine is the copper mine in Utah. Copper mining has played a vital role in the economic and social development of my state.Copper is used for variety of purposes. Most electrical appliances use copper. Moreover, water pipes, weather stripping, and wires use copper. Copper is used for making automobiles, ships, airplanes, and various other materials that we use on a daily basis.Copper in Utah is mined in open pit mines. They are severely impacting the environment. The hazardous pollutants, such as lead and arsenic, emitted during the mining process are affecting the fish and wildlife habitats in the nearby areas. Apart from impacting wildlife, the mines are polluting the groundwater in our state.Copper mining in Utah has positively affected economic development in the state. However, it has negatively affected wildlife and groundwater.
Explanation:
If human sperm and eggs were produced by mitosis instead of meiosis, they would be diploid cells, possibly resulting in a zygote with an excess of chromosomes. This imbalance could lead to nonviable offspring and developmental complications, as necessary components for early development are only present in the egg cell.
Currently, human sperm and eggs are produced by the process of
meiosis
, which results in
haploid cells
that contain half the number of chromosomes as the parent cell. If, hypothetically, sperm and eggs were produced by mitosis, they would be
diploid cells
with a full set of chromosomes similar to normal body cells. With such a change, sexual reproduction, as we understand it, could not occur, as the fertilization event would result in a zygote with four sets of chromosomes, creating a significant imbalance in genetic material. This could potentially lead to numerous complications and abnormalities in the offspring, likely making them nonviable. Additionally, critical components necessary for early development are present in the cytoplasm of the egg cell, without which, no subsequent development would occur. In conclusion, the production of sperm and egg cells via mitosis instead of meiosis would fundamentally alter human reproduction and could potentially lead to severe problems in offspring development.

Answer:
Is made of phospholipids
Explanation:
The cellular compartment of all eukaryotes is bounded by a membrane called cell/plasma membrane. The membranes in cells are similar in structure and majorly composed of phospholipids that builds it.
The phospholipid component are arranged in two adjacent layers in biological membranes, hence, called phospholipid bilayer. The phospholipid bilayer is said to be AMPHIPATHIC because it contains two hydrophobic fatty acids and a hydrophilic phosphate head in its structure. This amphipathic nature of the cell membrane confers semi-permeability of substances upon it.
