In the absence of substance M, a hypothetical LM operon is turned off. If substance M is abundant, it can bind to the repressor,

Andrei [34K]

Answer:Inducible;inducer

Explanation:

Induction is the phenomenon of increased synthesis of protein or and enzyme in response to certain signal. Such enzymes are called inducible and the signals are called inducer. Induction is turning ''on''the switch of a gene.

When M is present in the medium, M binds the repressor protein. The repressor-M complex is inactive which does not bind to the operator region of LM. Now RNAP can transcribe the structural genes of LM.

M switches the gene ''on''. Hence M is an inducer of LM. LM is an inducible operon

Main features of Solar System, Main facts of solar system

iren [92.7K]

Answer:

The main features of the solar system:

The Sun is our nearest star.

The planets orbit the Sun.

The time taken to orbit the Sun increases with distance from the Sun.

Gravity keeps the planets in orbit around the Sun and the moons in orbit around their planets.

From the Sun, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. You might need to be able to recall this in the exam.

The planets go around the Sun in slightly squashed circular elliptical orbits.

Pluto is classified as a dwarf planet or planetoid. It has a highly elliptical or eccentric orbit.

You discover a genus of lizards that contains two extinct species and five living species. The oldest fossils from the genus bel

Crank

Answer:

The evolution of the species might occur due to the change in the environmental conditions and the mutation in the organisms. The organism that can adapt in the environment will survive better.

The lizard species is present in the Ethiopian biogeographical region but now its two living species is in Neotropical biogeographic region and three species is in Australian biogeographic region. This might possible due to the fact that Neotropical and Australian lineages might have the common ancestor that were earlier originated in the Ethiopian region. The continental drift might have occur that breaks the Ethiopian biogeographical region and the species are present in the different island.
