Answer:
a. Bacteria cannot carry out splicing.
Explanation:
Human genes contain non-coding sequences called introns. Transcription of genes produces primary transcripts that undergo post-transcriptional modifications to produce mature mRNA. These modifications include removal of introns, the addition of 3' poly-A tail and 5' cap. The splicing of introns from primary transcripts is followed by ligation of protein-coding sequences exons to produce mature mRNA. The mRNA leaves the nucleus and serves as a template for protein synthesis.
Splicing of introns requires specific machinery such as several small nuclear ribonucleoprotein complexes, etc. which are not present in a prokaryotic cell. Therefore, a eukaryotic gene like the gene for human growth hormone is not expressed in a bacteria cell as these prokaryotic cells cannot carry out the splicing of introns from pre-mRNA.
The total batches of cupcakes that you make with one small bag of sugar will be 22 batches
From the question, we are given the following
Weight of a small bag of sugar = 2.265kg = 2265grams
Since 100g of sugar to make one batch of cupcakes, then:
100g = 1 batch ... 1
In order to get the number of batches of cupcakes can you make with one small bag of sugar, we can write:
2265g = x ... 2
Divide both expressions;
100/2265 = 1/x
100x = 2265
x = 2265/100
x = 22.65 batches
Hence the batches of cupcakes that you make with one small bag of sugar will be 22 batches

Answer:
the answer is phytoplankton
Attached is an image that wherein the question is being referred from.
There are choices for this question namely:
A- gravity increased the downward flow of the trapped water
B- metabolism of the elodea plants absorbed CO2 from the water
C- heat from the light source caused the escape of dissolved gas
<span>D- light caused the elodea plants to photosynthesize, releasing O2 gas
</span>
The correct answer is that
light caused the Elodea plants to photosynthesize, releasing O2 gas. Choice A is not true as if gravity increased the downward flow of the water, then the model without light should have air accumulated in the test tube too. In Choice B, while it is true that the plant may have absorbed the dissolved CO2 in water, this does not explain why there is gas on top of the test tube. Choice C may only evaporate the water, not cause the escape of dissolved gases. In choice D, however, light caused the Elodea plants to perform photosynthesis releasing O2 gas compared to the other model without light wherein the plant cannot perform photosynthesis thereby not releasing O2 gas therefore no gas is seen on top of the test tube.
Fermantion and cellular respiration in that they both begin with series of reaction known as glycosis, which break glucose molecules into smaller pyruvate molecules
