<h2>Answer:</h2>

The substances which cannot be separated are called elements.

<h2>Explanation:</h2>

An element is a type of particle having a similar number of protons in their nuclear cores. For instance, the nuclear number of oxygen is 8, so the component oxygen comprises all iotas which have 8 protons.

One hundred eighteen elements have been recognized: the initial 94 happen normally on Earth, and the rest 24 are manufactured ones. There are 80 components that have at any rate one stable isotope and 38 that have solely radionuclide, which rot after some time into different components.

Glucose is broken down in the chemical processes of aerobic respiration.

Papessa [141]

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is, 

Aerobic respiration is takes place in four stages :-

Glycolysis
The link reaction
The Krebs cycle
Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

<h3>Whereas, </h3>

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

In human muscles,  Lactic acid + Energy
In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.

In mitosis the spindle fibers connect to what

IrinaK [193]

Answer:

During mitosis, the spindle fibers are called the mitotic spindle. ... Long protein fibers called microtubules extend from the centrioles in all possible directions, forming what is called a spindle. Some of the microtubules attach the poles to the chromosomes by connecting to protein complexes called kinetochores.

Spindle fibers move chromosomes during cell division by attaching to chromosome arms and centromeres. A centromere is the specific region of a chromosome where duplicates are linked. Identical, joined copies of a single chromosome are known as sister chromatids

Would you use an observational, experimental, or modeling approach to study a rare, endangered bird species

son4ous [18]

Answer:

The correct answer would be - observational approach.

Explanation:

Observation approach is the research technique that involves the observation of the subject or participates behavior in their natural habitat or state. This will be one of best approach to study.

Similarly when characterizing new findings various aspect of experimental, Observational details or modelling approaches will help in identification , classification and nomenclature. However, in comparison to experimental and modeling approach is more appropriate method for the rare endangered species.

Thus, the correct answer would be - observational approach.
