OLEGan [10]

Answer:

c. Magma composition and cooling rate.

Explanation:

A rock cycle can be defined as a concept used to describe the continuous process that leads to a rock's creation, formation, transformation from one form to another, destruction and reformation over a specific period of time. The natural phenomenons that influences the rock cycle are weathering, plate tectonic activity, erosion, etc.

Basically, the three (3) main types of rocks are; metamorphic rock, sedimentary rock and igneous rock.

All igneous rocks are produced from magma (lava) and formed at the Earth’s surface, thereby, causing them to have a coarse texture and dark colors.

Generally, the cooling and solidification of magma (lava) leads to the formation of an igneous rock, either when the melted rock is still inside the continental crust of the Earth or at volcanoes on the Earth's surface.

Hence, magma composition and cooling rate determines the type of igneous rock that forms from magma. Some examples of an igneous rock are granite, obsidian, tuff, basalt, rhyolite, andesite, pegmatite, dacite, scoria, pumice, etc.

Explain the biological structure hierarchy of the human body and the role of homeostasis in maintaining the body. Include the fo
Nuetrik [128]

Answer:

1. Biological structure of the human body

The human body is organized in different levels according to their complexity.

The levels are the folowing (increasing complexity).

1. Atom (N, O, C,..)

2. Molecule (Protein, lipids, water...)

3. Organelle (mitochondria, golgi apparatus,...)

4. Cell (blood cells, bone cell,..)

5. Tissue (connective tissue, epithelial tissue,..)

6. Organ (lungs, kidney,..)

7. Organ system (skeletal system, muscuar system,...)

8. Organism (the human body)

Each of the levels is formed by an agrupation of the previous level. For example, cells are formed by a number of organelles, and a group of cells form a tissue.

Cells are the basic units of structure of the body, and there are different types of them.

2. Homeostasis

Homeostasis is a process of the body by which the organism works to maintain a stable internal environment, while adjusting to changes in the external environment.

This process is possible because of the work of both the nervous system and the endocrine system. While the first controles the body's activities and detects the necesity of adjustments, the second regulates the activities by using hormones.

jarptica [38.1K]

Answer:

Regulatory gene

Explanation:

Transcription is one of the major processes that occurs during gene expression. It is the transfer of the genetic instructions in DNA to mRNA. A strand of mRNA is made using complementary base pairs.

However, there is need for gene expression to be regulated.

Gene regulation refers to the mechanism that acts to induce or repress the expression of a gene. These include structural & chemical changes to the genetic material, binding of proteins to specific DNA elements to regulate transcription. These proteins that influences transcription by binding to specific nucleotide sequences (DNA segments/gene) are referred to as REGULATORY PROTEINS and those involved in regulating transcription of genes are called TRANSCRIPTION FACTORS.

Regulatory proteins controls the rate and manner of gene expression by binding to specific genes, thus, making it easy or hard for RNA polymerase (enzyme that attaches to DNA to synthesize mRNA molecule) to bind to the promoter of that gene.

Transcription factors (regulatory proteins) that promote gene transcription are called ACTIVATORS while those that decrease are called REPRESSORS.
