Answer:

Chloroplasts

Explanation:

Chloroplasts are the double membrane-bound organelles that are mostly present in leaves of the plants. Chloroplasts have chlorophyll pigments in their thylakoid membranes and enzymes for the Calvin cycle in the stroma.

Presence of chlorophyll pigment allows the Chloroplasts to serves as a site for photosynthesis as these pigments trap the sunlight required for the process.

Carbon dioxide and oxygen enter and exit a leaf by diffusion. which structure(s) on a leaf allow(s) this process to happen?
Montano1993 [528]
The stomata and their guard cells allows this happen.

Stomata is like a hole or gap on a leaf, most of them are present in a bottom side of the leaf, since waxy cuticle is not present over there. And 2 guard cells make up a stomata.

Guard cells are able to control the size of the stomata, depending on the situation. For example, the guard cells close up during day time because a lot of sunlight may cause more water loss.

In conclusion, guard cells and the stomata are the main structures that allow carbon dioxide and oxygen (water too) diffuse in and out of leaves.

Why do you think weather scientists use percentages instead of saying “it will definitely rain today”?
grigory [225]

Answer:

Right now, I am in college for climatology, but before I decided on climatology, I was taking classes in Meteorology, the study of weather. So, I will answer your question. All meteorologists like to be right, but since the weather is so spontaneous, it is really hard to be right. Meteorologists use percentages because it helps them be professional. Also, because, different parts of the region where they are may or may not get the rain. I don't know where you are from, but I will use my hometown. In McAlester, Oklahoma, there may be a 70% chance of rain, but in another part of the region at Tulsa, Oklahoma ( which is 91 miles north of McAlester) there may be a 40% chance of rain. The difference in the percentages can vary from how stable the environment is, altitude, location, and terrain. That is two of the reasons why Meteorologists use percentages to predict weather.

Where does the RNA cap go? The tail?
Rufina [12.5K]

Answer:

The post-transcriptional modifications in the mRNA produced as a result of the transcription in eukaryotes provide many advantages to the mRNA.

The two post-transcriptional modifications are the addition of  7-methylguanosine cap at 5' end of mRNA called capping whereas the addition of the poly(Adenyl) tail at 3' end called tailing.

The advantages of capping are:

1. Protection of nascent mRNA from the degradation.

2. Recognition by transcription factors helps in translation.

The advantages of tailing are:

1. Protection of the mRNA from enzymatic degradation in the cytosol.

2. Transcription termination

3. Export of the mRNA from the nucleus
