Answer:

Meteorites, which are the very components of our planets (through the process of accretion), are the remnants of the Solar System's origins. Dating meteorites thus allows us to give a lower age to the Solar System (4,56 billion years old).

Anastaziya [24]

Answer:

The reaction with adenine dideoxynucleotides will run furthest in the gel

Explanation:

In dideoxy sequencing (also known as Sanger sequencing), the DNA template is used to run four different reactions in which only one class of dideoxynucleotide (ddNTP) is added. These four different ddNTPs (i.e., ddATP, ddCTP, ddTTP or ddGTP) act as terminators during DNA synthesis. Moreover, the additional factors required for DNA synthesis including standard deoxynucleotides (dNTPs), DNA polymerase and site-specific primers are added in equal volumes to prepare these four different reactions. Thus, during electrophoresis, the sizes of the DNA bands will depend on the specific ddNTP used in each reaction. In this case, the reaction containing ddATP (capable of terminating DNA synthesis at the 5' end) will run furthest in the gel.

A light microscope that makes the specimen appear light on a dark background is called a(n) _____. compound microscope electron
AnnZ [28]

The right option is; dark-field microscope

A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.

Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.

kondor19780726 [428]

Muscular system, gastrointestinal system and excretory system are required for the process.

<h3><u>Explanation:</u></h3>

Cheetos is a nutrient rich diet which is actually a snack. Its a hard food, so needs to be chewed which uses the muscular system for chewing. The muscles of jaw like masseter and temporalis are required.

Now as the Cheetos are crunched, they need to be digested into finer particles and finally into the absorbable particles. This uses the gastrointestinal system. The enzymes digest the food and the villi of small intestine helps in the absorption.

The absorbed food are metabolized in liver and some excretory products are produced. They are excreted using the excretory system.
