Correct answer choice is :

<h2>A) Scientists ask testable questions and devise ways to answer those questions through experimentation or observation</h2><h2 /><h2>Explanation:</h2><h2 />

A scientist is someone who manages scientific analysis to improve knowledge in an area of concern. In traditional obsolescence, there was no real early analog of a modern scientist. Alternatively, philosophers interested in the philosophical study of nature named natural philosophy, an ancestor of natural science.

seeds that are planted upside down are still able to grow into mature plants which explanation best explains this phenomenon?

pav-90 [236]

Answer:

This question is incomplete but the completed question is below

eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?

(a)The roots change into branches, and the branches turn into roots.

(b)The roots grow toward the force of gravity, and the shoots grow away.

(c)The plant will become a smaller version of a mature plant.

(d)Roots always grow toward the dark, and shoots grow toward the light.

Two options appear to be correct here: options B and D

Explanation:

Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b

What role does oxygen play in a plants life?

aleksandrvk [35]

Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival

Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of:

SOVA2 [1]

Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents.
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.

The nucleus is primarily stores most of the cell's *

Ganezh [65]

<u>Answer</u>:

The nucleus is primarily stores most of the cell's DNA.

<u>Explanation</u>:

It is made up of two chains which coils around each other, together they form a helical structure tat further carries the genetic information, which will help in the development, functioning and also the growth and reproduction in all known organism and in viruses. The nucleus is stored in it and the nucleus has the genetic material. They are composed of the nucleotides, in which each nucleotide has four nitrogen. These nucleotides are together joined with covalent bond to each other. Together they have the biological information.
