Why is this considered a nonscientific question?<br> "What color is a great horned owl?"
madam [21]

Answer:

The question "What color is a great horned owl?" does not require the scientific method to be used for getting an answer hence, it is not a scientific question. This question does not require any hypothesis or any other method. It can easily be answered by just looking at the horned owl.

A scientific question has to be a question from which a hypothesis can be made. The hypothesis can be tested through experiments and observations. Results and conclusions from the experiments would result in answering that question.

Advocard [28]

Megasporangium  tissue gives rise to the female gametophyte.

<h3>What is the name of the diploid tissue that gives rise to the female gametophyte?</h3>
  • Three of the four haploid megaspores worsen into antipodal cells interior the female gametophyte.
  • The central cell of the female gametophyte contains two cores that when fertilized gotten to be the endosperm.
  • Megasporogenesis alludes to the advancement of megaspores from the megasporocyte, the cell that experiences meiosis.
  • Meiosis of the megasporocyte core comes about within the arrangement of four haploid megaspore cores.
  • In most taxa, meiosis is taken after by cytokinesis, coming about in four megaspore cells.
  • This design is named monosporic megasporogene - sis; since of the four megaspores delivered, as it were one of them contributes to the female gametophyte

The correct option is b

Explanation:

Phospholipids are lipids that contains a phosphate group, which forms the "head" of the molecule and is hydrophilic (water loving). The "tail" of phospholipids is made of two fatty acids which are hydrophobic (water fearing).

Based on biology and neo-Darwinism, _____ explains how environment selects organizations for survival or extinction.
lutik1710 [3]

Given what we know, we can say that biology and neo-Darwinism both support the idea that natural selection explains how the environment selects organizations for survival or extinction.

<h3>Natural Selection. </h3>
  • This concept is often summarized by the phrase "survival of the fittest".
  • This refers to the ability of an organism to adapt to its environment.
  • The better-adapted organisms will live to pass on their genetic information, thus changing the organization of the species.
  • Those not able to do so will face extinction.

Therefore, since natural selection involves the survival or extinction of a species based solely upon their ability to adapt and change their genetic organization in response to their environment, we can say that this concept helps to explain how the environment selects organizations for survival or extinction.
