The top of the stigma is sticky where pollen attaches making it easy for pollination to occur.
Lena [83]3 years ago
6 0

Explanation:

  • The structure of the stigma aid in pollination because stigma identifies and traps the pollen to fertilize ovary and pollen germinate in the stigma, it is the most essential part for the reproduction of the plant.
  • stigma is sticky so that it can hold the pollen which falls on it.
  • Stigma is an entrance zone in the flower and plays a crucial role in reproduction.

In the absence of other information, you can predict that an organic molecule with the empirical formula of c12h24o12 is a_____.
Rzqust [24]

The empirical formula of c12h24o12 is a carbohydrate.

<h3>Carbohydrate</h3>

A carbohydrate is a biomolecule made up of carbon (C), hydrogen (H), and oxygen (O) atoms, often with a hydrogen-oxygen atom ratio of 2:1 (as in water), and so having the empirical formula Cm(H2O)n (where m may or may not be different from n). All molecules that meet this exact stoichiometric criterion are not, however, automatically categorized as being carbohydrates.

The term is most frequently used in biochemistry, where it is used as a synonym for saccharide, a class of compounds that includes sugars, starches, and cellulose. The four chemical categories of saccharides are monosaccharides, disaccharides, oligosaccharides, and polysaccharides. The smallest carbohydrates, monosaccharides and disaccharides, are sometimes referred to as sugars.

Due to decay of ⁴⁰K, cow’s milk has a specific activity of about 6X10⁻¹¹mCi per milliliter. How many disintegrations of ⁴⁰K nucl
FromTheMoon [43]

When we discuss radioactive isotope activity, we consider how many decays or disintegrations occur per unit of time. Therefore, activity is determined by the quantity of disintegrations over time. Ah, the becquerel, or B que, is a measurement unit that is widely used to quantify activity. It is equivalent to one decay or one disintegration per second. Therefore, we occasionally shorten it to one d. per s. The curie, denoted by the letters C I, is a second unit we used to denote activity. The result is 1.4 times 10 to the negative 11. Curie's modify this to Beck, Carell's One Curie from curies. His 10 times 10 times 3.7 's Becca Rell And we are aware that one Decorah is equal to one Decay every second. Therefore, we multiply by 1.4 x 10 - 11 times. There are 5 to 5 decays per second, or 3.7 x 10 to the 10 refined. There is one more conversion because my query now asks us what this would be in decays per minute. We multiply 60 by 5.5 to 5 to get the number of decays per minute from our activity and decays per second. This yields 32 decays per minute, which is significant at 30.

<h3>What are isotopes?</h3>

Isotopes are two or more atom types that have the same atomic number (number of protons in their nuclei), location in the periodic table, and chemical element but have distinct nucleon numbers (mass numbers) as a result of having a different number of neutrons in their nuclei. Although the chemical properties of each isotope of a particular element are almost identical, they differ in their atomic weights and physical characteristics.
