What are the differences between prokaryotic and eukaryotic gene expression? Group of answer choices Regulation of transcription is identical in both.
Answer:
See the answer below
Explanation:
The gene expression involves a series of steps that have to do with encoding the information in genes as mRNA - transcription - and the translation of the codes into proteins - translation.
The process of transcription and translation happens within the same space in prokaryotic cells. Since they have neither nuclei nor membrane-bound organelles, both transcription and translation happen in the cytoplasmic space of the cell simultaneously.
However, in eukaryotic cells, transcription happens in the nucleus because the DNA is located within it. Once this takes place, the mRNA produced is transported outside the nucleus into the cytoplasm where they engage with the ribosome and tRNA in a translation process.

Why is the amount of fertilizer known as the independent variable?
Answer:
You can think of an independent variable is the variable that is being varied by you the experimenter or scientist; it is the input/"cause"/the tunable variable. A dependent variable is the response/output/"effect".
There is also the control variable, which are variables that stay constant throughout. You generally have only one independent variable and many control variables so that you can properly disentangle cause and effect.
A simple example might be say you want to know if a certain brand of fertilizer helps your crops grow. You want to see how much fertilizer you need for optimal growth without using too much. What is the independent and dependent variable? (Highlight below for the answer!)
The independent variable is the amount of fertilizer you put on the crop. It is the variable that you, as the tester, vary yourself. The dependent variable is how much your crop grows. What about the control? It is the crop you choose to use the fertilizer on (e.g., corn, wheat, peas). Certainly, comparing the influence of fertilizer between corn and peas would not definitely tell you whether the fertilizer is effective; if you compared two different crops, you would have other confounding variables out of your control, so you want to test it only on one crop at a time.
I put cause and effect in quotes because you may run into one of many cause/effect fallacies (or mistaken beliefs). It is possible (and often happens in research) where you plot what you think is an independent and its dependent variable, but the reality is quite different! There are two common types- spurious relationships and spurious correlations. A spurious relationship is one in which a direct cause/effect relationship is concluded incorrectly when in fact there is a lurking or hidden variable unaccounted for. One commonly cited example is say you find an increase of death by drownings and ice cream sales. It would be incorrect to infer that eating more ice cream causes more drownings, or vice versa. The lurking variable that can explain both is hot weather (i.e., people eat more ice cream and go swimming more to cool down). A spurious correlation is incorrectly inferring the extent of how related two variables are (not necessarily a cause/effect relation, but something used often in statistics). Here is a website that illustrates quite ridiculous correlations (a pet project of a graduate student), emphasizing that correlation is not causation.

Answer:
The statement "All living things are composed of eukaryotic cells" is incorrect and is not a part of Cell Theory
Explanation:
Eukaryotic organisms are not the only living things in existence. Micro organisms such as bacteria are referred to as prokaryotic. This classification is done on the basis of the presence or the absence of a nucleus. Eukaryotic organism are more evolved and contain a well defined nuclear structure.
When a membrane protein is radioactively labeled during synthesis and followed through the various organelles in the secretory pathway, all the radioactivity is concentrated in the cis-Golgi apparatus six hours after the protein synthesis. This suggests that the protein
a. is misfolded and being degraded in the cis-Golgi.
b. contains a KDEL sequence near its C-terminus.
c. has a membrane-spanning domain length equals the
d. thickness of the cis-Golgi membrane.
e. was imported directly into the cis-Golgi posttranslationally.
f. has a mannose-6-phosphate tag.
Answer:
C. has a membrane-spanning domain length equals the thickness of the cis-Golgi membrane.
Explanation:
Secretory pathway is the pathway that transport proteins to the cell surface membrane. For this, the membrane proteins are labeled radioactively and move through the various organelles to carry the proteins to the surface membrane.
After six hours, all the radioactivity is concentrated in the cis-Golgi apparatus this means that The protein carries membrane-spanning domain which widens or make the cis-Golgi menbrane thick.
Hence, the correct answer is "C".

The water-to-land transition occurred independently several times in the protostomes. Which of these is not an example of an adaptation for terrestrial living that may have arisen by convergent evolution? Internal respiratory structures Eggs with a covering that minimizes water loss Internal fertilization Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Answer:
The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air
Explanation:
the fundamental problem that an aquatic animals face during its progress to land to save the egg or embryo from parching. So they have developed cleidoic eggs where undeveloped organism stay implanted inside extra embryonic layers, for example, amnions and are secured in egg shells. These eggs have minute pores so embryo can make gas exchange.
This egg shells forestall water misfortune. Interior treatment, however are available in certain sharks, yet it is for the most part a variation of land creatures. Explicit intromittent organs have been created for moving of sperm in to female. In contrast with water , gaseous movement is in land creatures is happen through advancement of lungs which contain numerous alveoli where gaseous exchange is occurred. Decreased surface to volume ratio decrease productivity of gas exchange , not increment.
Thus, The incorrect statement is : Decreased surface-to-volume ratios to increase the efficiency of gas exchange in air

Pinky's science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder.
Answer:
See the answer below
Explanation:
The complete question: Pinky's science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder. Consider if data was collected consisting of the average number of cricket chirps at different temperatures in her backyard. What's the independent variable?
The independent variable would be the temperature.
Independent variables are variables that produce effects on another variable while remaining unaffected themselves. They can be manipulated in the course of a research in order to measure the kind of effects they exert on other variables - the dependent variables to be specific. The dependent variables are the actual variables needed to test the hypothesis of a research.
In this case, a variation in temperature was observed to have an effect on the chirping frequency of crickets. Hence, the independent variable would be the temperature.
A sequence of base pairs that codes information for a specific trait is called a ________. A. Nucleotide B. Gene C. Chromosome D. Enzyme
Base pairs are nucleotides that are the structural unit of the genetic material. Bases code for the traits that are in the form of genes. Thus, option B is correct.
What are genes?Genes are the primary unit involved in heredity and are composed of nucleotides that make the DNA. They are involved in the production of proteins through the process of translation.
Genes are made of alleles that code the traits inherited from the parents through the method of reproduction. The dominant alleles are expressed whereas the recessive are masked and not visible in the phenotype.
The alleles are made of chromosomes and DNA that are in turn made of nucleotide sequences, sugar, and a phosphate group.
Therefore, the base pairs code for the traits called genes.
