Terrestrial or inner planets like Mars and Venus were formed near the Sun where the solar system's temperatures were very high.
Answer:
The correct answer is - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin.
Explanation:
An ectotherm is an organism that also known as the cold-blooded animal. Such animals experience body temperature regulation based on the external atmosphere or condition like sunlight and other condition.
This group includes a different group of animals such as reptiles, amphibians, fishes, and invertebrates. From the given options the cold-blooded animals or ectotherm are known are - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin as their internal physiological conditions does not play a major role in regulation of body temperature and external conditions play a major role.
Thus, the correct answer is - Western fence lizard
, Xenopus (African clawed frog)
, Fruit Fly
, Turtle
, and Sea urchin.

An operon is a stretch of DNA consisting of an operator, a promoter, and genes for a related set of proteins, usually making up an entire metabolic pathway.
operon is a functional unit of gene.
This cluster of gene transcribed together to give a messenger RNA which further give rises to protein.
operator in operon is the site where repressor binds.
promoter is where Mrna binds , where our genes are transcribed
structural genes, they code for the enzyme that are involved in this metabolic pathway.
Operons have an important role to play as they produce protein for the cell this serves them energy, the protein is produced only when energy is required.

Answer:
The correct answer to the question, 'which of the following scenarios is representative of how agricultural practice can affect the environment' is A. Option A is chosen because it is the only option that refer to another environment which is different from that of the farm. When fertilizers are washed to nearby ponds as a result of erosion, it causes a lot of negative changes in the pond. For instance, the chemicals in the fertilizer can be poisonous to some of the smaller organisms in the pond, this will result in the death of these organisms. Fertilizer run off can also cause excessive growth of plants such as algae in the pond. This may block out the light necessary for the survival of the organisms in the ponds and may also reduce the amount of oxygen available to the organisms living in the pond.
