They are controlled by more than one gene

LekaFEV [45]3 years ago

Answer:

The correct answer would be "they are polygenic traits".

Polygenic traits are those which are controlled by at least two different genes.

As more than two genes are involved in controlling a single trait, so they show more variations as compared to the traits which are controlled by a single gene.

For example, height is controlled by at least three genes and thus six alleles are involved in regulating height.  

Polygenic traits often show a bell-shaped curve in a population.

What does nitrogen fixation accomplish?
alexgriva [62]

Answer:

A. It allows plants to use nitrogen to grow.

Explanation:

However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.

Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).

It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.

ad-work [718]

Answer: B- Bacteria

Explanation: Bacteria are infinitesimal organisms that have single cells that grow in different atmospheres. They have an easily understood inside arrangement. Their cells are normally surrounded by two shielding coverings which are an external cell continuous vertical structure and a cell pliable sheet-like structure acting as a boundary inside. However, some bacteria do have a third shielding sheet furthest from the center named the capsule.

lubasha [3.4K]

Answer:

The Golgi apparatus is especially developed in cells that have functions related to the secretion of substances, such as cells of the nervous or endocrine system.

Explanation:

The Golgi apparatus is the organelle responsible for most of the modifications that lipids and proteins undergo once their synthesis in the endoplasmic reticulum (ER) has been completed, that is, the Golgi apparatus is a cellular organ whose function is to manage the proteins synthesized by the endoplasmic reticulum in order to transform and export them to the rest of the body. It is made up of flattened cisterns (middle zone) with an entrance zone or face and an exit zone. The proteins enter the Golgi apparatus and are later transported to these cisterns where they are modified by enzymes.
