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

Which of the followings statements is true?
SVETLANKA909090 [29]

Answer:

The correct answer is option D, Unconfined aquifers​ are found between two layers of impermeable soil or rock.

Explanation:

An unconfined aquifer is not confined by rock layer on both of its side. Usually the ground water level (GWL) is considered as the upper layer of unconfined aquifer. Also the rocky layer found on the other side of the unconfined aquifer is not impermeable as the major source of recharge of unconfined aquifer is the seepage of water through is permeable layer or through rain.

5. Compare the energy emitted by waves with long <br> wavelengths to waves with short wavelengths
irinina [24]

Explanation:

The energy emitted by long wavelength waves are smaller to those emitted by short wave lengths.

The energy of a wave is a function of its wavelength and frequency.

  • The wavelength of a wave is the distance between its crest.
  • Frequency is the amount of waves that passes through a point in a period of time.
  • Energy of a wave is directly proportional to frequency and inversely proportional to wavelength.
  • The higher the frequency of a wave, the more the energy.
  • Waves with a high wavelength carries very little energy.
  • Long wavelength radiations have a long wavelength as the name implies. They carry very little energy and have low frequency. Examples are infra-red.
  • Short wavelength radiations have short wavelength. They carry very high amount of energy and have very high frequency. Examples are x-rays and gamma rays.
