Answer:
If the Earth was not tilted on its axis, there would be no seasons. And humanity would suffer.
Explanation:
When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.
Hope this helps!

Answer:
D) There are two major subunits, each with multiple proteins.
Explanation:
The ribosome is a complex structure made of RNA and proteins. Both prokaryotic and eukaryotic ribosomes have two subunits: small and large subunits. Each of these subunits is made of specific types of ribosomal RNAs (rRNA) and a number of different proteins.
For example, the 30S subunit of <em>E. coli</em> ribosome has 21 different proteins while its 50S subunit is made of 33 different types of proteins along with rRNA.
Likewise, the 40S subunit of a eukaryotic ribosome is made of 33 proteins while its 60S subunit has 47 proteins. The eukaryotic ribosome contains a total of 80 different proteins.
<span>Lafora disease is the most severe teenage-onset progressive epilepsy, a unique form of glycogenosis with perikaryal accumulation of an abnormal form of glycogen, and a neurodegenerative disorder exhibiting an unusual generalized organellar disintegration. The disease is caused by mutations of the EPM2A gene, which encodes two isoforms of the laforin protein tyrosine phosphatase, having alternate carboxyl termini, one localized in the cytoplasm (endoplasmic reticulum) and the other in the nucleus. To date, all documented disease mutations, including the knockout mouse model deletion, have been in the segment of the protein common to both isoforms. It is therefore not known whether dysfunction of the cytoplasmic, nuclear, or both isoforms leads to the disease. In the present work, we identify six novel mutations, one of which, c.950insT (Q319fs), is the first mutation specific to the cytoplasmic laforin isoform, implicating this isoform in disease pathogenesis. To confirm this mutation's deleterious effect on laforin, we studied the resultant protein's subcellular localization and function and show a drastic reduction in its phosphatase activity, despite maintenance of its location at the endoplasmic reticulum.

The strengths of the cell model are :
easy to understand and
All cell processes are represented/shown
The weakness of cell model is :
The cell model does not represent the cell accurately (organelles are not shown )
RNAs involved in transcription are not shown in the cell model as well
The cell model is a visual representation of a biological cell as entities of their own. Some strengths of the cell model is that it is easy to understand when studied because most of the processes of cell formation are clearly shown in the model while some of the weakness that a cell model possesses are that all the organelles of the cell are not represented (this makes the cell model an inaccurate representation) also the RNA involved in transcription are not shown in the cell model.
Hence, we conclude that the weakness and strengths of the cell model are an inaccurate representation of the cell, absence of RNAs, easy to understand and proper representation of cell processes.
Answer:there would be a larger population of producers
Explanation:
Since there needs to be primary consumers, the population of producers needs to be plentiful in order for the primary consumers to survive.
