Explanation:

No specific major exists in roller coaster engineering, though a design team is typically made up of structural, electrical, and mechanical engineers. ... Students interested in designing roller coasters should consider including additional physics, mathematics, and drafting courses to their curricula.

Which of the following statements is true regarding anabolism?

navik [9.2K]

Answer:

B) In anabolism, larger molecules are made from smaller molecules.

Explanation:

Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.

For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.

Option B is true regarding anabolism.

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.

a dna restriction enzyme cuts dna at a specific sequence. if a restriction enzyme that cuts at the dna sequence gaattc were used

vitfil [10]

Four bands appear in gel electrophoresis. Gel electrophoresis is an experimental method used to separate mixtures of DNA, RNA, or proteins by molecular size.

DNA is negatively charged, so when a current is applied to the gel, the DNA migrates towards the positively charged electrode. Fragments are ordered by size because short DNA strands migrate through the gel faster than long strands. There are some basic steps for performing gel electrophoresis outlined below. 1) pour the gel, 2) prepare the sample, 3) load the gel, 4) run the gel (expose it to an electric field), 5) stain the gel. Gel electrophoresis is a technique for separating biomolecules by size. Separation of these molecules is achieved by placing them in a small pore gel and creating an electric field across the gel

Adapt extinct mutation

lisabon 2012 [21]

That organism will survive in the future which adapt themselves according to the environment.

<h3>What is fitness?</h3>

Fittest is the term describes living things that are best suited to their environment.

Species that survive are the ones that adapt, make or meet changes.

Florida has a rich fossil record spanning from the Eocene to recent times. Florida fossils are often very well preserved.

Two examples of land animal fossils found in Florida are the giant sloth and the saber-tooth tiger.

Some animals unable to adapt to the changing environment became extinct .

Living things mutate over time to meet their changing environment.

This biologist, Darwin, studied evolution in the 1800s.

The glyptodont was a giant, armadillo-like animal with a spiked tail that once lived in Florida.

The Origin of Species is a book written in 1859 about natural selection.

Nature selects the fittest for survival because they have useful traits.

Changes may occur in animals due to changes in the sequence of base pairs in their DNA, and this is known as a mutation.

Oldfield mice show variation in the color of their fur.

The survival of the light-colored old field mice on Florida's Gulf Coast is an example of the process called adaptation.

Evolution is a controversial theory that has survived much criticism.
