Answer: Crystal

Explanation:

The<u> texture of a rock refers to the size of a crystals</u>, that helps in understanding how a rock formed and how the crystallization of magma has taken place.  The texture of an igneous rock depends upon the following factors, such as-

  • Cooling rate  of magma
  • Type of magma and its viscosity
  • Crystallization order of different minerals

Some of the types of igneous textures are as follows-

  • Aphanitic texture- Here the crystals are too small to be seen with naked eye. It often forms when lava cools rapidly after eruption. Example, basalt.
  • Phaneritic texture- Here, the crystals are large enough and easily distinguishable, formed under the earth's surface. Example, granite.
  • Porphyritic texture- Here, larger crystals are embedded in the middle of smaller crystals or matrix. Example, porphyry-granite.
  • Pegmatitic texture- Here, the rock contains large and massive crystal. Example, pegmatite.
  • Glassy texture- When the rocks are comprised of glassy materials, then it is called glassy or vitreous texture. Example, obsidian.

astra-53 [7]

Answer:

ecological dominants

Explanation:

In an ecosystem, organisms of same and different species are usually found. However, some organisms appear too commonly than others in that particular ecosystem. These commonly observed organisms (plants and animals) due to their large numbers are called DOMINANT species. An ecological dominant species is that which numerically outshines its competitors in an ecosystem.

A species may be dominant because it is better adapted to certain processes than Its competitors e.g. getting resources, disease resistance etc. or even deters its competitors. Hence, they appear large in number. This is the case of the abundance of pinyon pine and juniper trees along the desert slope of the sierra nevada mountains in california. In that ecosystem, these two plants dominate, hence, will be referred to as ecological dominants.

1. Write a statement that uses (correctly) the terms gamete, fertilization, and zygote. (2)
Mazyrski [523]

Answer:

The zygote simply is the fertilized ovum or egg cell or female reproductive cell. It is the result of the process of fertilization of the fusion of the male reproductive cell (gamete) and the female reproductive cell ( gamete). In human, the zygote is the resulted cell of fertilization of the sperm and the ovum. It is diploid or 2N which means it contains two sets of chromosomes; one set from the male and the other from the female.

The gamete is the reproductive cell. There are two types of gametes; male gamete and female gamete. In human, the male gamete is called the sperm and the female gamete is called the ovum. The gamete is the last stage of the reproductive cells to be completely formed.

Fertilization is the fusion of the male gamete and the female gamete to form the zygote. Fertilization may be external as in fish or internal as in human.
