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

Scientists at Russia’s Vostok Station in eastern Antarctica drilled the longest ice core ever recorded. They compiled this graph
Wittaler [7]
The data supports the fourth choice, that increasing air temperature and CO2 levels correlate with a decrease in dust concentration.

The first choice is unlikely to reflect dust concentration, and is more likely to be for air temperature. The second choice is false, because the dust concentration is more of a decreasing trend. The third choice is not true, as the spikes in air temperature and atmospheric CO2 concentrations seem to occur simultaneously, implying a positive correlation.

Zinaida [17]

Answer:

Following are the answer to this question:

Explanation:

In option a:

There are many ways, which can be defined as follows:  

  • It keeping cells "qualified," use heat shock and handle ions like Ca and ice incubating.
  • It uses Micro-injection with DNA.  
  • It uses the biolistics or even the process of gene-gun.  

The stable cell charts indicate simple and definitive outcomes when their relationship to specific results. Moreover, relative to temporary cell lines, findings are more reliable and error-free. These lines also easily break and much less.

In option b:

Radio tests including linking tests could be used  

The Ligand Binding Assays is an analysis, that is based on the binding of ligands to antibodies, or other macromolecules. Its existence and distance of formed ligand-receptor complexes are defined using a system of measurement that is usually electrical or fluorescent.

In option c:

The method for measuring the levels of cell growth is accessible and the  Another way is to measure the metabolism within the same cell. So many color pigments were also accessible that can permeate an organism as well as react with some proteins as well as other factors, and that can effectively identify a color final product.  

Throughout relation to the amount of metabolism exercise, cell proliferation could be evaluated by researching one or even more cell markings. The BrdU limited liability assessment is a very well-published illustration.  

Its specific antibody can detect BrdU and high BrdUincorporations levels are linked to high levels of cell proliferation.  Command cell without DNA receptor growth hormone.

In option d:

The cell growth will stop after each use of RNA interference ( RNAi). The p007 formation as well as the effect on growth caused by the intrusion will be a goal. If development is delayed effectively, the theory will be tested successfully to a cell without any of the required DNA. The RNAi is the free cell

In the process of glycolysis, what happens to glucose after it crosses the cell membrane into the cytoplasm of the cell?
malfutka [58]

Living organisms display the property of metabolism, which is a general term to describe the processes carried out to acquire and use energy. We know that people need to eat, and in our foods are various kinds of nutrients that our cells use. One large group of nutrients in our foods is carbohydrates, which supply our cells with glucose.

11) In C3 photosynthesis, the reactions that require ATP take place in A) the light reactions alone. B) the Calvin cycle alone.
valentinak56 [21]

Answer:

In C3 photosynthesis, the reactions that require ATP take place in

B) the Calvin cycle alone.

Explanation:

In C3 PLANTS PHOTOSYNTHESIS OCCUR IN TWO STEPS-

1. LIGHT stage , WHICH TAKES PLACE IN LIGHT. In this stage water is split and ATP is released.

2. DARK stage, which takes place in dark. This the stage where calvin cycle takes place which require ATP, i.e energy. In this process sugar is produced with help of carbon dioxide. In this carbon dioxide is accepted by 5- carbon molecule ribulose-1, 5-biphosphate, which result into two molecules of 3- phosphoglycerate. this three carbon compound. hence is called as C3 pathway. hence C3 plants.
