<span>The correct answer is C) photosynthesis and respiration. It powers almost all trophic chains and food webs on the Earth is called Photosynthesis. The process which organisms oxidize organic molecules and derive energy known as ATP from the molecular bonds that are broken is called respiration.</span>
Answer:
They have uncoiled to form long, thin strands.
Explanation:
Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes. The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.
Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.
Answer:
The correct answer is genes.
Explanation:
The genes are the fundamental units of inheritance. The genes are passed to the offspring from the parents and comprise the information required to specify traits. The genes are aligned one after another on the compositions known as chromosomes. A chromosome comprises a lengthened and single molecule of DNA, of which only a part equivalent to a single gene. In humans, there are about 20000 genes aligned on their chromosomes.
at the replication fork, you have 2 DNAP's. One is on the leading strand and the other is on the lagging strand. Now you into a problem of DNAP's not moving in sync with each other. The synthesis on the leading strand is much faster than the lagging strand because the lagging strand needs to make an RNA primer and then extend the primer (okazaki fragment synthesis/maturation). So DNA synthesis will not be complete on one of the strands.
There is a model that explains what happens during DNA replication. The model is called the Trombone model.
You have 2 DNAP's linked together by a tau protein (2 tau proteins) and both tau proteins are bounded to beta clamp loader. This makes the holoenzyme complex.
The difference between a hot spot volcano and the volcanoes from Ring of Fire can mainly be seen in the way of formation and functioning. The hot spot volcanoes are far away from any tectonic plate boundary and they manage to penetrate the crust over them and come out on the surface to usually create volcanic islands. The activity of the volcanoes from the Ring of Fire depends directly from the activity between the bordering tectonic plates, and as the borders move over time, the volcanoes stop existing, and new ones rise in the direction where the boundary moves.
The similarity can be seen in the type of eruptions, and that usually both types of volcanoes form volcanic islands.
Example for a hot spot volcano is Mauna Loa on Hawaii.
