CHAPTER 4 ANIMAL KINGDOM Animal Kingdom is characterized by multicellular‚ eukaryotic organisms. The cells lack cell walls. They ingest and digest food (holozoic)‚ hence they are heterotrophic. Higher forms show elaborate sensory and neuromotor systems. Majority of them are motile. Reproduction is mostly sexual and embryological development is present in them. About 1.2 million species of animals are described till now. The classification helps to assign a systematic position to newly described

take part in high energy sports (football) and animals are able to hunt‚ so lipids act as energy storage. His can also be good because it can provide insulation. Increased body fat levels in winter reduce heat losses to the environment; this is good for wild animals. Also lipids are a source of metabolic water. During respiration stored lipids are metabolised for energy‚ producing water and carbon dioxide‚ so it acts as a buoyancy for aquatic animals. Phospholipids which are a class of lipids form

Sexual reproduction has been successful among flowering plants and mammals‚ it is brought by the following requirements. Firstly is the transfer of gametes. Sexual reproduction is only made successful when the gametes of the male and female from a pair of parents of different sexes are transferred to meet each other. In mammals‚ the male gamete is transferred to the female body by copulation to meet with the female gamete in the oviduct for successful fertilization. However‚ the ovum is only

A compound is a substance made of two or more different elements (a mixture). 2. What is the periodic table? A periodic table is where the chemical elements are organized based on their atomic number (number of protons in the nucleus)‚ electron arrangement‚ and chemical properties. 3. Give two examples of each of the four major mineral groups (silicates‚ carbonates

Over many years anthropologists have been studying many concepts that deals with the past development of animals and humans. Over the years‚ anthropologists found many differences between the appearance‚ behavior and mind of humans and animals.

For instance‚ humans have their opposable thumbs‚ good eyesight‚ and also the most important detail is that

Christine Otieno Estimating Osmolarity of plant Cells(potato and celery)by percentage change in weight Using different sucrose concentrations Introduction The purpose of this experiment was to estimate Osmolality of plants cells i.e. Potato and celery by converting the observed change of weight in different sucrose concentrations. The hypothesis assumes that the solute concentration of the plant samples would be indirectly proportional to the weight; there would be decrease

There are two processes of cell division that are very tricky. They are mitosis and meiosis. Many people often get confused with the two about their functions. They both serve as mechanisms for cell division. However‚ quite significantly‚ they are very much different in fact and occur in different situations. Mitosis and meiosis take place in different places. This is one of the first major differences between the two. Mitosis takes place within somatic cells (cells that make up the body)‚ while
