Hello Everyone! Last week's poll question was Which of the following animals are the closest relative of a Hyena. Now let's talk about the Hyena first, The Hyena lives in the Sahara Desert in Africa which is filled by extreme desert conditions. The typical diet for the Hyena are zebras, wilder beast, buffalo and topi. Although many people view the hyena as a scavenger it is mostly a hunter. They can hunt alone or in a group called a clan if they are hunting large prey. The Hyena's closest relative is the MONGOOSE. There are three types of hyena species, the spotted, brown and striped hyenas. They also live in groups called clans. These clans are dominated by the larger females and the clans can grow to have up to 70 members.

Last week's poll was "Which of the following nutrients is the LEAST important? The correct answer is............... FATS! Although fats are part of the 4 major nutrients it can cause numerous problems if a person's body fat is beyond the normal limit but at the same time it also has a lot of uses in our body.
Functions of FATS:
1. Insulating material for the body. (Keep warm)
2. Mixes with vitamins so the body can absorb it.
3. Acts as a cushioning material for the body.
4. Contains a large amount of energy.

A liger is the offspring of a lion father and a tiger mother. Though the tigers involved are usually of the orange coloration. Ligers share characteristics of both their parents. Some look very like lions, while others show their tiger heritage strongly.They usually chuff like a tiger and roar like a lion, but without giving the typical lion grunt at the end. Their vocabulary is made up both of lion and tiger sounds. The liger pelage usually has the typical tan lion coloring, with tiger 'candle flame' shaped stripes or spots running through it. Most typically, the striping is located across the back and hindquarters, while the abdominal area is spotted. These spots are inherited from the lion parent, even though they are not normally obvious in adult lions.
On ligers, tiger ear spots may or may not be present and the same applies to the tiger facial ruff. A male liger may have a leonine mane, but this is much more modest than on the lion and many male ligers have little or no head decoration at all.
Hybrid animals usually display what is known as 'hybrid vigor'. This means the offspring grow much larger and faster than either parent, and it appears that many hybridizations cause gigantism.

Hi everyone, I decided to make this site to help you in your biology lessons. I will post some of the materials here for those students who needs to catch up on lessons because they were absent and students who still needs clarifications about a previous lesson. Students can also post questions and inquiries about certain topics. ***(Only questions about the topics should be posted otherwise it will not be entertained.)
There will be occassions that I will post assignments and announcements for the class.
