The diagram below represents a flower, the reproductive structure of some plants. Most
Evgen [1.6K]

Answer:

The stigma, a female structure which collects pollen and passes it to the ovary

Explanation:

<u>The structure represented by the letter A in the diagram is the stigma.</u>

The <u>stigma of a flower represents part of the female reproductive structure</u>. The surface of a mature stigma is sticky and as such, it is able to attract pollen grains from the anther. A pollen that lands on the stigma germinates and its pollen tube grows through the style of the stigma down to the ovule where one of the sperm cells of the pollen fertilizes the egg cell of the ovule to form a diploid zygote and the other sperm cell fuses with the polar nuclei of the ovary to form a triploid cell that eventually becomes the endosperm.

<em>The sepal and the petal are labeled as D and C in the diagram respectively while the stamen is made up of B and H.</em>

inna [77]

Explanation:

  1. Siphons in Mollusca are tube-like structures in which water (or, more rarely, air) flows. The water flow is used for one or more purposes such as locomotion, feeding, respiration, and reproduction.
  2. The siphon propels the squid through the water in the opposite direction to which the siphon is pointing, much like jet propulsion. To use this jet propulsion, the squid takes in water through the large opening and then closes off the opening.

natima [27]

Answer:

The correct answer is option C. "Longer beaks allow the birds to better access seeds in bird feeders".

Explanation:

Since climate change makes more difficult for "<em>Parus major</em>" birds to feed from its primary source of food in gardens, the birds are adapting to access their second source of food, which is the bird feeder. Longer beaks allow the birds to better access seeds in bird feeders, therefore, the birds are developing longer beaks in order to adapt to their new conditions.
