Abstract

This examination paper acknowledges the spectacular diversity of reproductive adaptations for survival of various categories of land plants. It describes a typical life cycle of a land plant that reproduces via spores. It also identifies the different parts of Plant organs and their functions such as cell organelles, parts of a land plant, and epidermal cells. A microscope is an important tool for examination of biological specimens, including cell’s internal structures called organelle and is important in magnifying the focused area. Plants are classified into four main groups, namely, ferns, mosses, flowering and confers. This paper finds that ...

{Author Name [first-name middle-name-initials last-name]} {Institution Affiliation [name of Author’s institute]} A cell is a form of the miniature factory that encloses a distinct chemical system that is involved in structural maintenance, homeostasis, energy generation and reproduction. Every organism is made of these structural living units. The cell divides and produces more cells and assists in the growth of the organism. There are two types of cells, eukaryotic and prokaryotic. Eukaryotic cells are characterised by a membrane-bound nucleus enclosing the genetic material. The Eukaryotic cells can be divided into three main parts, plasma membrane, cytoplasm, and nucleus (Cooper & ...

Question 1

Binary mission in prokaryotes Mitosis and Meiosis in eukaryotes Question 2 The development of embryos as well as the growth and development of bodies. Important in asexual reproduction. Question 3 The term cell cycle refers to an ordered set of events leading to cell growth and division into two daughter cells.

Question 4

Interphase is a phase of the cell cycle characterized by the absence of cell division. During this phase, the cell obtain nutrients, the organelles duplicates, protein synthesis takes place, and cells duplicate its genetic material (its chromatids). The genetic material is located in the nuclei of ...

Question 1

In mitosis, the number of chromosomes before and after cell division do not change. Mitosis results in daughter cells are having a diploid number of chromosomes as the parent cells.

Question 2

Mitosis is divided into four phases: Prophase- in this phase, the chromosomal material (chromatin) condenses forming compact chromosomes which are seen as two chromatids joined together at the centromere. The mitotic spindle also starts to assemble with the help microtubules Metaphase- In this phase, the spindle fibres become attached to the kinetochores of chromosomes. Chromosomes move to the equator and are aligned along the metaphase plate via spindle fibres ...

Lab 1: Ethical Issue in the Movie Gattaca. The epicentre of ethical issues in the movie Gattaca is the manner in which an individual ought to be judged. Should it be by the genetic composition one is born with or by the character traits, personality attributes and ambitions chosen by an individual? Vincent is born with genetic weaknesses that could result in ailments in the future. His genetic composition denies him access to his dream job despite the fact that he achieves the required grades in school and is a strong and athletic young man. As a result, Vincent designs a plan to ...

Microbiology is the study of microorganisms. Microorganisms are those organisms that are less than a millimeter in size and require the help of a microscope to view them. Microorganisms can be unicellular or multicellular but have very simple cell structure, unlike the highly developed, complex organisms such as larger animals and humans. Microorganisms are classified based on criteria such as their cell structure, pattern of growth, nutrition, reproduction method, etc. However, microbial classification is a challenging task due to the dual nature of some microorganisms that exhibit both animal and plant like characteristics. Some microorganisms are photosynthetic like plants but they also ...

1. How are Modern-day Psychologists different from Pseudo-psychologists? What do they believe? Modern psychology majors on the different areas of application of psychology. For example, the industrial psychology, social, behavioral, etc. and they belief that each of these fields have different models of behavior and mental processes. The modern psychologist believes in scientific research and evidence. On the other hand, pseudo-psychologist emphasizes on the sections of psychology without a scientific backing or any logical explanation. Pseudo psychologists overly rely on machines to explain occurrences rather than scientific research. 2. List and describe the four Goals of Psychology. ...

I do feel that the police are empowered by the state to enforce the law, limit civil disorder, and protect community’s property as the only constituted body of persons. They improve community relationships since they maintain and create a feeling of security in them as well as prevent conflicts and promote harmony in the society. They also provide responding to all possible help to the community in all arising situations either man made or a natural disaster and relief measures. Thus they build, develop and nurture the public with a positive relationship. They are known as the backbone of a state’s ...

Part 1

The police work efficiently with collaboration with the public thus; the police are the public. They nurture and build a positive relationship with the public. Police are paid in return to give total time attention to duties that are to serving each and every citizen according to interest of the community existence and welfare. For efficient operation of preserving the order, detect offenders, and prevent crimes they must form a partnership with the public thus improving the quality of existence and community’s safety (Broadhurst & Davies, 2009: 56). This contributes to promotion and preservation of public order. Police enforces and ...
