Answer:
A. True
Explanation:
Allolactose is an example of an inducer, a small molecule that triggers expression of a gene or operon. The lac operon is considered an inducible operon because it is usually turned off (repressed), but can be turned on in the presence of the inducer allolactose.
The suborganellar structure that will become visible after staining is nucleoid.
In the field of biology, nucleoid can be described as a region inside the prokaryotic cell in which the DNA is present.
The prokaryotes do not have a membrane-bound nucleus like the eukaryotes. Hence, the region where the genetic material of the prokaryotes is present is an irregular shaper structure referred to as the nucleoid.
When DNA is stained with a DNA-binding dye, the suborganellar structure that will become visible will be the nucleoid as it is the region where the DNA is present.

Answer:
problems of population growth are
- economic causes
- economic status
- Poverty status
- Occupational status
- Unemployment
Explanation:
1. Economic causes : the economy always affect the fertility rate of any country. parents in backward communities considered their children as sources of income in future. most of these parents think that producing more children is helpful addition to the workforce and a means to increase the agricultural production.Economic causes refers to those aspect of our life that affect the population size from economic point of view.
2. Economic status: number of children are more in agro based communities. economic status also increase the population.in agricultural countries like I was all the works are done manually so more level forces are working people are required. farmer think that if they have large family they will accomplish their works easily and they will not have to hire people. they will be able to save the unnecessary cost . In other words ,the polar parents give birth to many childrens. it helps to increase the population.
3. Poverty: Poverty is another important factor of population growth in every country.many people of their country are under the absolute poverty line.they think that the birth of a son is the prospect of income in the family and he will drive them away from the poverty-stricken life.earn more money to wipe out their poverty. similarly, many pop people are deprived of even basic needs. education becomes an additional need to them. Then, the same vicious circle of illiteracy binds them within the same boundary of inner ignorance and poverty. Therefore,poverty plays an important role to increase the population of any country.

Seed texture was observed by Gregor Mendel.
<h3>Mendel Laws:</h3>
Mendel focused on pea plants because they had features that were simple to observe and could reproduce sexually. Gregor Mendel explains his research with peas that demonstrated how genetics is passed down into distinct components. People have long been aware of the similarities between parents and children, in both animal and plant families as well as in human families.
The segregation of the two alleles of a particular gene into the gametes is described by Mendel's first law. The independent distribution of alleles from various genes from one another during gamete development is described by Mendel's second law. According to Mendel's law of dominance, only one form of a trait will manifest in the offspring of two parents who have distinct, opposing qualities. The sole phenotypic trait that the hybrid offspring will display is the dominant trait.

Answer:
A & C
Explanation:
In short terms, A & C are the only answers that have anything to do with the magnetic field. Solar wind is part of solar weather, and is involved in the creation of the other three answers. Auroras are formed through the interaction of solar wind and the oxygen & nitrogen in Earth's atmosphere.
