Discuss the purpose of guard cells and stomata on the leaves of plants.​

Biology

BabaBlast [244]3 years ago

Guard cells are located in the leaf epidermis and pairs of guard cells surround and form stomatal pores, which regulate CO2 influx from the atmosphere into the leaves for photosynthetic carbon fixation.

Stomatal guard cells also regulate water loss of plants via transpiration to the atmosphere.

Which organelles would create a basic protein that could be modified to move chromatids during metaphase?
bija089 [108]

The organelles would create a basic protein that could be modified to move chromatids during metaphase is the histine protien which is secreted from the RNA's.  

<u>Explanation:</u>

Histone protein is the protein that is associated with the chromosome. The chromatin fibres get condensed into chromosomes on these proteins.  

The chromatin fibre i.e. the DNA fibre gets to wrap itself around the histone octamer which is formed of two units of each of Histone H2A H2B H3 and H4. Then the H1 protein seals the turn and thus a chromosome is formed. These histone are produced in the S-phase of the cell cycle. This protein is transcribed into m-RNA's and then translated into protein.

2. If 10% of the bases in a molecule of DNA are adenine, what is the ratio of adenine to guanine in the same
sertanlavr [38]

Answer: Option D) 1:4

Explanation:

Recall that the sum of all nitrogenous bases in the DNA nucleotide is equal to 100%. And specific base pairings of Adenine to Thymine (A=T), and Cytosine to Guanine (C=G) must be equal.

So, the percentage of Adenine equal thymine, and that of cytosine equals guanine.

Now, A + T + C + G = 100%

So, if adenine makes up 10% of the DNA nucleotides, then thymine is also 10%.

Then, 10% + 10% + C + G = 100%

20% + C + G = 100%

C + G = 100% - 20% = 80%

Thus, divide 80% by 2 to obtain the individual percentage of cytosine and guanine. Each will take 40%

Ratio Adenine to Guanine is 10% to 40%

or 1:4 in simplest form

What type of species, if removed from the community, could lead to the collapse of the entire community?
Anon25 [30]

Answer:

The correct answer will be - Keystone species

Explanation:

Keystone species refers to the species present in a community which has a large effect or great influence on the surrounding environment.

The concept of Keystone species was introduced by the Robert T. Paine in 1969 to the species which help maintain the structure of the biological community.

The keystone species are called keystone species as its presence affect the other organisms directly and if removed from a community it will lead to the shift or change in the structure of the community.

Thus, Keystone species is the correct answer.
