Parent rock, also referred to as substratum, refers to the original rock from which something else was formed. It is mainly used in the context of soil formation where the parent rock (or parent material) normally has a large influence on the nature of the resulting soil.

During telophase of Mitosis nuclear membranes of two separated nuclei are formed around each set of chromosomes.  

<u>Explanation</u>:  

Mitosis is the process of cell division part of the cell cycle. Mitosis is classified into four phases which are prophase, metaphase, anaphase and telophase. In prophase the nucleolus disappears, chromosomes start to contents and the mitotic spindle starts to appear and bind to the kinetochore of centromere of the chromosomes. In metaphase nuclear envelope breaks down and the chromosomes becomes fully condensed and organized on the metaphase plate in the middle of the nucleus, during anaphase chromosomes are pulled back to their centromeres with the help of spindle fibers and during telophase the chromosomes starts to decondense, the nucleous reappears and nuclear membrane reforms and spindle starts to disappear.

Transcription starts at the template strand of DNA where mRNA attaches and is constructed from 5’ to 3’ direction. The nucleotides of the DNA strand is attached to either A, U, G, C ribosomal nucleotides. mRNA Dissembles when it reaches a terminating codon and then it attaches to ribosomal RNA where tRNA carries the amino and mRNA caries the code to construct proteins with the ribosome.

This image shows the various forces acting on a block of rock situated on a rock slope. What does arrow 4 represent?
AlladinOne [14]

Answer:

4 is gravitational force

Option B

Explanation:

This is a force diagram of a block on an inclined plane.

The force component is what makes up weight in the diagram. Weight is given as mass multiplied by the gravity.

Gravitational force acts downward and it is the force of attraction between all objects and the earth. It is directly proportional to mass.

Force 1 and 2 are both shear forces that acts parallel to the face of the incline. They are mostly expressed as frictional forces.

An ecological pyramid shows the transfer of energy. Which level will contain only 0. 1% of the total energy obtained from the Su
lora16 [44]

The energy level in the ecological pyramid with 0.1% of the total sun's energy is Tertiary consumers.

An ecological pyramid is described as the graphical representation of the different levels of the ecosystem. The pyramid is broad at the bottom with the maximum energy and sharp at the top with the minimum energy.

<h3>Which level contains 0.1% total energy?</h3>

In the ecological pyramid, the energy of the sun has been absorbed by the producers. At each successive level in the ecological pyramid, 10 % of the energy is passed, while the rest is lost.

The producers are followed by consumers. The energy with each of the level organisms is given as:

  • Producer - 100%
  • Primary Consumer-  10%
  • Secondary Consumer-  1%
  • Tertiary Consumer - 0.1%

Thus, the energy level in the ecological pyramid with 0.1% of the total sun's energy is Tertiary consumers.
