Match each organism with its phylum Pines Ephedra Palm-like plants Trees with fan-shaped leaves A. Gnetophyta B. Ginkgophyta C.
solong [7]

Answer:

Ginkgophyta

Explanation:

Gymnosperms are cone-bearing trees or Woody plants, which do not different greatly in their structure from the Woody angiosperms. Gymnosperms do not produce flowers but as seed plants that bear their seeds on scale-like leaves which are arranged spirally to form cones. The seeds are termed naked seeds because they are exposed to the air on the surfaces of the cone scales.

Gymnpsperms are grouped into four major divisions namely:

*Ginkgophyta

*Cycadophyta

*Corniferophyta

*Gnetophyta

1)DIVISION GINKGOPHYTA:The ginkgo tree cared maiden hair is the only surviving member of this division. It is found in the Orient(China and Japan) where it is cultivated as an ornamental tree because of the fan-like leaves. The leaves are *fan-shaped* with long petrioles.

2)DIVISION CYCADOPHYTA:The cycads abound in the tropics, mainly as ornamental plants. They are *palm tree-like* plants with a crowded crown of palm fronds.The leaves of Cuba's are deep green,waxy with large petioles.

DIVISION CONIFEROPHYTA:This is the largest group of Gymnosperms as it includes some of most economically exploited plants such as *pines* and Jupiter's. The pine tree is important as Christmas tree and conifers are generally important in the production of wood and paper

DIVISION GNETOPHYTA:This is the group of very unique Gymnosperms made up of three genera:Gnetum,*Ephedra* and Welwitschia.

Ephedra is a profusely branched shrub found in desert regions. It has whorl-like, scale-like, or needle -like leaves and jointed stem.

Hence, matching each with its phylum, we have:

Gingkophyta:Fan-shaped leaves

Cycadophyta-Palm-like leaves

Coniferophyta:Pine

Gnetophyta:Ephedra

Se the information from the article to answer the question.
Svetach [21]

Answer:

A. near-Earth objects.

Explanation:

Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.

When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.

A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.

Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.

Hence, near-Earth objects may pose a collision danger to planet earth.
