The arrangement of placenta within the ovary is known as placentation. Ovules are attached to the inner wall of special tissues which are called placenta, the ovules are attached by the small stalk called funicules. There are several type of Placentations i.e. Basal, Marginal, central, axile, parietal.

Placentation in Plants of Barbados is Marginal, Marginal Placentation is when in which the placenta forms a ridge along the ventral suture(The line of fusion where the margins of the mega-sporophypl join)  of the ovary and the ovules develop on two separate rows is known to have marginal placentation.

\huge\textbf{Gynoecium}

Gynoecium is a female whorl of the flower. It is composed of Carpels. Carpel is composed of Sigma, Style and Ovary.

Gynoecium in Pride of Barbados is Monocarpellary(one carpel), Ovary Superior(An ovary attached above other floral parts is termed superior), consist of one chamber(unilocular), many ovules are present along the margin. Seed is non-endospermic and Fruit is legume.

<h2>_____________________________________</h2><h2>\huge\textbf{Flower:}</h2>

Flower is the reproductive organ of a plant. Morphologically it is very modified shoot. It is developed in the axil of leaf or at a.p.e.x of stem & branch. Flower is also produced in group which is called the inflorescence. If stalk called pedicel is present then flower is called pedicellate, If pedicel is absent Flower is called sessile. If small leaf or scale called bract is present then flower is called bracteate, if absent then called ebracteate.

Flower in Pride of Barbados is Pedicellate, complete, bisexual, zygomorphic, perigynous, showy and scented pentamerous.

<h2>_____________________________________</h2><h2>\huge\textbf{Features}</h2>
  • Butterflies are the primary pollinators of Caesalpinia pulcherrima and the pollen is carried primarily on their wings.
  • Plant of Barbados is poisonous
  • It has some anti-inflammatory substances.
  • This plant grows in sunny regions thus It has great heat resistant feature
  • It can grow easily in very dry soil.  This is due to its drought resistant features.

Hypothesis: If i add the egg to vinegar then the shell will dissolve within 24 hours
nadezda [96]

Answer :

Vinegar is a weak acid. This is used to make a naked egg. When an egg is added in the vinegar for one day / 24 hrs, it reacts with the eggshell.  The calcium carbonate shell gets dissolve.

Then an egg without shell is formed and the size of the egg does not change. The calcium carbonate reacts with acetic acid and forms carbon dioxide.

When the shell-less egg is kept in the vinegar for 48 hrs i.e. 2 days again, the water content in it enters into the eggs through the membrane. Then the egg gets somewhat bigger.

Otherwise, for 24 hrs, vinegar is acting like an isotonic solution and only dissolves the shell. This experiment would be done for showing the osmosis process through the cell membrane.

Which location is not appropriate for hand washing after working with human material in the laboratory
brilliants [131]

A hand washing sink in the break room is not an appropriate location for washing hands  after working with human material in the laboratory.

A vital part of laboratory safety is hand washing. In fact, this 20-second method is regarded as one of the most crucial steps utilized to stop chemicals, radioactive materials, and microbiological agents from infecting you and the area around you.

Even though gloves should be used when handling hazardous items, adequate hand washing should still be done on a regular basis. If you don't wash your hands right away after taking off your gloves, germs could spread to your mucous membranes and infect you, or they could contaminate neighboring surfaces and endanger other lab workers.

Every laboratory that uses chemical or biological agents must have access to at least one sink for hand washing, ideally close to the room exit. To prevent contamination, the sink must be cleaned frequently, and soap must be available for hand washing.

Answer:

The percentage of people carrying sickle cell gene increases.

Explanation:

People carrying the Sickle Cell gene have low chance of Malaria because the sickle cell enables the body to detoxify abnormal red blood cells from the body.
