Answer:I believe it is Carbon
Explanation:The basic building block of all living things is a cell. The basic element would be carbon.
The action of phagocytes considered a nonspecific response because it is a response to any type of harmful substance with out any specificity.
Phagocytosis is a process in which a cell engulf any molecule using its plasma membrane. Phagocytes provide non specific defense mechanism as it the first line of defense of our body. our immune system has to tackle several types of foreign particles, Viruses, Bacteria and harmful proteins. This non specificity of action makes the response quicker than the specific
Yes
Explanation:
Graphite is one of the two allotropes of carbon. It is crystalline and has well ordered crystal patterns.
- Graphite is made up of layers arranged in a hexagonal structure weakly bonded by van der waals forces.
- Graphite structure is made up of hexagonal planes of carbon weakly bonded to one another.
- This structure makes graphite soft and slippery and makes them applicable as lubricants.
- The other crystalline type of carbon is diamond.
- Diamond has close-packed crystal structure responsible for its extreme hardness.
- The arrangement of these atoms permeates through the structure.

Answer: Conservation
Explanation:
The sustainable development aims at conservation of natural resources so that these can fullfill the demands of present as well as future generation.
If the resources are not conserved than their concentration will deplete in near future.
In a process called <u>Synapsis</u>, paired homologous chromosomes align randomly at the cell equator. This occurs during stage <u>prophase I</u> of cell division.
Synapsis refers to the pairing of the homologous chromosomes in the meiosis occuring in the reproductive cells. Meiosis I is divided into four phases called the prophase I, metaphase I, anaphase I and the telophase I. Prophase I is the longest phase of meiosis which is further divided into leptotene, zygotene, pachytene, diplotene and diakinesis.
During the zygotene of meiosis I, the paring of the homologous chromosomes called the synapsis takesplace which is facilitated by the protein structure called the synaptonemal complex. The paired chromosomes are called the bivalents. This facilitates the homologous recombination.
