The heterotroph hypothesis of the origin of life states that basic organic building blocks formed from inorganic molecules under

the primitive conditions present early in Earth’s development. These building blocks combined to form polymers, such as crude proteins. Dr. Sidney Fox wished to add to the heterotroph hypothesis of the origin of life by synthesizing simple proteins from a mixture of amino acids. Which statement below best states an alternative hypothesis Fox could have used to frame his research?

Answer:

1) abiotic synthesis of small organic molecules (monomers)

2) joining of monomers into polymers

3) packaging of these molecules into protobionts, droplets with membranes that maintained a distinct internal chemistry

4) origin of self-replicating molecules that eventually made inheritance possible

anyanavicka [17]

Working in a lab means working under controlled environment. If in the generation 1 and generation 3, the number of bird’s increases or decreases in number, the possible conditions for this would

- The amount of food increased or decreased

- If a flock’s beak type made it easier to pick up the available food, the flock grows and vice versa

Justification: if the beak type for generation 1 makes the food intake easier, it will grow which ultimately decreases the food for the generation 3 which has un-supportive beak type.

The slide image shows epithelium tissue found in the bladder. What is the function of the tissue indicated by the arrow?
Ede4ka [16]
Epithelial cells are mainly used for protection; in the urinary tract, these tissue cells are used to protect the bladder from toxic urine. The tissue can also expand to hold larger quantities of urine.

Select ALL the correct answers.A forest was cleared to build a road. Which two would be the most likely effects on the ecosystem
Kryger [21]

Answer:

Some species will develop adaptations to survive in the deforested land.

Some populations will migrate out of the deforested area.

Explanation:

The deforested land will be able to support large trees eventually in the future, and animals cannot instantly adapt to anything.

Therefore, the most logical answers are populations will migrate to forest lands and species will eventually develop adaptations to help them in the newly deforested land.

I hope this helps! :)

1. The nucleic acids DNA and RNA carry genetic information and are made up of many . 2. Myoglobin is a protein that binds oxygen
OverLord2011 [107]

Answer:

1. Nucleotides

2. Amino acids

3. Amino acids

4. Glucose

Explanation:

All the above substance described are biomolecules. They are all polymers i.e. complex molecule bond together in a long repeating chain, made up of simpler subunits called monomers. The monomers of the different biomolecules outlined above are:

1. The nucleic acids, DNA and RNA carry genetic information and are made up of many NUCELEOTIDES. A nuceleotide is a chemical combination of a five carbon sugar (pentose), phosphate group and nitrogenous base. These nucleotides are arranged sequentially to form nucleic acids (RNA and DNA).

2. Myoglobin is a protein that binds oxygen molecules and is a polymer of AMINO ACIDS. Amino acids are the building blocks of proteins. They are arranged to form a 3D structure that determines the function of the protein.

3. Insulin is a protein hormone that regulates blood glucose levels and is a polymer of AMINO ACIDS. All proteins are made up of the amino acid but the protein's function is dependent on the 3D structure formed by the amino acid sequence.

4. Animals store energy in the form of glycogen, a carbohydrate made up of thousands of monosaccharide (GLUCOSE). Glycogen is a polysaccharide made up of many monosaccharide units. These units are glucose molecules that are multibranched to form the glycogen that stores mainly in the liver and muscles of animals.
