Answer:
antero-posterior
Explanation:
the axis that determines the body pattern from the nose to the tip of the tail
Answer:
Petri plates are incubated upside down to prevent contamination.
Explanation:
The plates are always incubated inverted or turned upside down on their covers during storage. This is done to prevent evaporation if plaque is stored for long periods, which can affect the growth efficiency of bacteria, or allow contamination by multiplying unwanted organisms such as mold.
Once the plaques have been filled with a damp suspension of bacteria, it should be allowed to evaporate shortly before overnight incubation. However, a moderate amount of moisture will still be present. If plaque is not inverted during incubation, bacteria will not be able to attach to the culture medium properly, which will either prevent them from growing and forming colonies properly or will encourage the growth of undesirable microorganisms.
Any of these results will invalidate the experiment. In addition, any condensation or moisture can cause streaking, which will make it difficult to select and analyze separate colonies. After bacteria form colonies, plaque is also stored upside down to maintain moisture levels.
Answer:
A. light penetration
Explanation:
Water clarity refers to how clear a water is, and it is a measure of how far/deep light can penetrate into such a water body. A water that is not clear is said to be TURBID. Several factors affect the clarity of a water body and they include;
- Phytoplankton, which refers to floating algae on the water body. An accumulated growth of phytoplankton can affect the penetration of light into the water, hence, making the water unclear.
- Suspended sediments can also block the penetration of light into the water, reducing water clarity.
- Nutrients in form of fertilizer or waste materials can also make water unclear.
Therefore, LIGHT PENETRATION DOES NOT IMPACT WATER CLARITY, rather it is dependent on water clarity.
Answer:
plastic consumption is like using a lot of plastic and plastic waste is when you throw out a lot.
Explanation:
consumption means like eating /using
waste means throwing out / not really using
hope this helped. btw I'm not sure if this is right but I hope it is!
The slow twitch muscle fibres have a higher count of mitochondria which means it can process quicker, it receives a energy, it receives a good blood supply since it has a high amount of capillaries, which means it has a good supply of oxygen, which helps to maintain the use of the aerobic energy system for longer, making type 1 fibres more effect for endurance, while the type 2 fast twitch have less mitochondria and rely more on glycolysis.
