A ____is a piece of DNA that is transcribed.

GrogVix [38]

Answer:

D. A mutation causing uncontrolled cell division

Explanation:

Cell division is controlled by various mechanisms. Any mutations in the genes regulating the cell division lead to uncontrolled cell division. Loss of control over the process of cell division leads to the formation of tumors.

These tumors may cause cancer if they are transformed into malignant tumors. Hence, a mutation that causes loss of control over cell division is harmful.

Which statement describes how pioneer species and climax communities are different?

Lorico [155]

Answer: D). Primary species have large numbers of offsprings, and climax communities contain species that have small numbers of offsprings.

An ecological succession is a process of gradual changes occurs in a biological community with respect to changes in the non-living abiotic factors (water, air and sunlight) and with respect to time until the ecosystem attains stability. Primary or pioneer species are the species which invade the previously barren and primitive landmass for their survival. These species make the environment suitable for the growth of other species. These grow and develop in the initial stages of succession. These species are simple organisms which reproduce asexually and produces large number of offsprings. Examples are lichen and moss. Lichen grows on the surface of rocks and acids released by them causes withering of rocks into soil which facilitate the growth of mosses and other plants. Climax community develops in an ecosystem after replacing many previously inhabiting species. Climax community develops in the end of the ecological succession. It contains species which are highly complex and uses sexual reproduction for the production of offsprings which are less in number as compared to those produced by pioneer species by asexual reproduction.

A parent cell gives rise to daughter cells with identical genetic information. Which of the following data supports the idea tha

Yuri [45]

Answer:

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Explanation:

We are looking for a parent cell that gives rise to daughter cells with identical genetic information.

In simpler words, we are looking for something that makes 'clones' of itself.

In this statement (second option), the parent and daughters are all feline skeletal muscle cells.

A feline skeletal muscle cell undergoes cell division, resulting in two feline skeletal muscle cells.

Other incorrect choices: (All having to do with reproduction).

A child has brown eyes; one of its biological parents has green eyes, and the other has brown eyes.

This situation has two parents, each with a different trait. The child takes one of the parent's trait. The parents did not make a 'clone' of themselves.

A human sperm fuses with a human egg cell, resulting in the development of a new human.

The parents don't make 'clones' of themselves. The sperm did not make more sperm. The egg did not make more egg cells.

A long-stemmed plant reproduces with a short-stemmed plant, and the offspring are all long-stemmed.

The offspring plant only took the trait from one of it's parents. Also, whole plants are not individual cells.
