Answer: a. Photo-periodism

Explanation:

The relative length of the day is considered as a major factor in the development of plants, particularly in sexual reproduction. The plants were grouped considering that the flowering and fruiting occurs only when the length of the day is within certain limits so that these phases are achieved only in certain times of the year. Therefore, some species respond to long days, while others respond to short days, and still, others are capable of responding to all day lengths. The name and meaning of each group became as follows:

Short Day Plants: They are the species that bloom in smaller photoperiods than a critical maximum.

Long day plants. These are the species that bloom in larger photoperiods than a critical minimum.

Neutral day plants: They are those that bloom in a wide range of the photoperiod.

Answer:

The correct answer would be D)  tissue.

In biology, the level of organisation from simplest to complex level can be summarized as:

Organelles → cells → tissues → organs → organ systems → organisms → populations →communities → ecosystem → biosphere.

It is clear that tissue is organization level that exists between cells and organs.

When similar cells are assembled together to perform specific function, the assembly or this organization is said to be the tissue.

There can be different types of tissues such as muscle tissue, nerve tissue et cetera.

Similarly, tissues arrange themselves to carry out specific function in the form of organ.

For example, heart is made up of cardiac tissue.

How is the blending theory of inheritance useful in genetics?
makkiz [27]

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance. Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

<h3>What is blending inheritance?</h3>

Blending inheritance is an outmoded biological theory from the nineteenth century. According to the theory, children inherit any characteristic as the average of their parents' values for that characteristic.

As an example, a cross between a red flower variety and a white variety of the same species would result in pink-flowered offspring.

Charles Darwin's theory of pangenesis, in which every part of the body contributes to an egg or sperm, implied blending inheritance.

Darwin's theory of natural selection was founded on the premise that blending inheritance would average out any novel beneficial trait before selection could act.

Thus, this can be the importance of blending inheritance.

Oksana_A [137]

Answer:

Human genome has various replicons.

Explanation:

A replicon which is a unit of DNA, has potential to get replicated independently. So, the DNA replication occurs simultaneously at various replicons as a result of which human genome takes much less time than estimated to get replicated .

In contrast to this, prokaryotes like E.coli have only one origin of replication and thus one replicon due to which replication is restricted to once per cell cycle.
