Animals do not have cell walls‚ but do generally are multicellular‚ reproduce sexually and have gap junctions. Animals are ingesting heterotrophs; fungi have absorptive nutrition. Development order: fertilization‚ cleavages‚ blastula‚ gastrula and metamorphosis. Ancestor of animals: protozoa (choanoflagelate) Know Animal Taxonomy including Lophotrocozoa!!!! Only animals have hox genes Sponge=perifera=parazoa=lacks true tissue Eumetazoa=everything besides sponge Cephalization=sensory organs

people have different types of meetings‚ whether it is formal/informal‚ social gatherings‚ job focused or community based. All of which are mainly to give information‚ get information‚ develop opinions and make decisions. Meetings are established to accomplish a goal or purpose‚ but what makes a meeting effective? I have discovered that meetings really boil down to three things: 1. They achieve the meeting’s objective. 2. Meetings take a minimum amount of time. 3. Participants are left

They have an open circulatory system Clams shells are thick while mussels are usually thin. Mussels live attached to something while clams live in the sand. Clams live alone‚ while mussels are usually in large groups. The oldest part of a clam’s shell is called the umbo and is located at the hinge of the clam. The rings on a clam’s shell indicated how old the clam is. Its part of the

existence of cell organelles within the cell structure‚ allowing the function of the cell itself to occur; It was necessary to increase magnification by utilising an alternate source radiation (alternate to light).The result was the electron microscope‚ whereby the short wavelength and negative charge of electrons when supplied with energy allowed for greater focusing with electromagnetism. This method bends the path of the beam in the manner of a lens to light. Cell Organelles and the variation

arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues‚ and cells of your body and removes the carbon dioxide and waste products that are made. The pulmonary circuit carries blood to the horse’s lungs to be oxygenated and then carries the oxygenated blood

How does computer software and hardware work together? This is kind of a complex question. I think the most important thing connecting software and hardware would probably be the register. Commands or services requested by the software are encoded into binary values of 0’s and 1’s and are written into a register. For example‚ some register may hold a value of "01101100". This encoding has a total of 8 bits. Each value of either 0 or 1 is called a bit‚ and 8 bits are called a byte. At the hardware

ANIMAL CELL MODEL ORGANELLE FUNCTIONS Cell membrane: Separating the interior of the cell from the outside environment‚ the cell wall is selectively permeable‚ only letting certain things through. It is involved in a variety of cellular processes‚ such as cell adhesion and cell signalling. Cytoplasm: The fluid that fills the cell‚ cytoplasm uses its dissolved enzymes to break down larger molecules. The products can then be used by the organelles that are suspended in the cytoplasm. Cytoskeleton:

A system is a group of organs that work together and provide an organism with an advantage for survival. It is the most complex organization in your body and the final level of the progression from cells to tissues to organs and then systems. Systems work alone and with other systems to allow your body to maintain homeostasis. Homeostasis is a stable internal environment that allows you (and your cells) to survive. While every one of your systems is needed to survive‚ your nervous system is the

[pic] Cells and Their Organelles The cell is the basic unit of life. The following is a glossary of animal cell terms. All cells are surrounded by a cell membrane. The cell membrane is semipermeable‚ allowing some substances to pass into the cell and blocking others. It is composed of a double layer of phospholipids and embedded proteins. Color and label the cell membrane tan. Plant cells have an additional layer surrounding them called the cell wall. The cell wall is made of nonliving

3.3 There are many agencies that we work with to help with children and young peoples development. When we look at behavioural development‚ social interactions and speech development all these agencies link together. We use nursery transition days to help the child settle into their new environments and arrange intake visits and meetings with the school for a smoother transition. Social services is used if we have any concerns of a child’s well being so then police and a designated social worker
