A sunflower is an angiosperm, and a gingko is a gymnosperm. Which best describes the life cycles of sunflowers and gingkoes? I.
dalvyx [7]

The correct statements are I, III and IV.

An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.

Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.

How long will r136a1 live? ​
loris [4]

A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years. And if the star is very small, with a mass only a tenth that of the Sun, it can keep fusing hydrogen for up to a trillion years, longer than the current age of the universe.

Identify some beverages that are mixtures. Classify them as solutions, suspensions, or neither. Explain your classifications.
Minchanka [31]

Answer:

See explanation.

Explanation:

Hello.

In this case we can for instance take into account the following mixtures:

- Orange juice.

- Tea.

- A soda.

- Salty water

- Coffee.

Thus, since the orange juice is a suspension as long as it contains different sizes of orange pulp particles that cannot be dissolved mostly because of its organic nature.

Tea can be a solution when we place a tea bag in a cup with warm water since just soluble components of tea are successfully dissolved in the water. Moreover, homemade tea based on some plants are fruits may behave as a suspension due to the oraginic particles that are not dissolved in the water yet suspended.

A soda is a solution of some water-soluble compounds, gaseous soluble carbon dioxide and water which are homogeneously distributed in the solution.

Salty water can be a solution if you put some salt in warm or just cold water and wait until it dissolves completely.

Coffee can be also a solution or suspension depending on how it is made, which type of coffee is used and the amount of coffee added to the hot water.

Best regards.
