SashulF [63]1 year ago
5 0

Explanation:

Almost all eukaryotic proteins are subject to post-translational modifications during mitosis and cell cycle, and in particular, reversible phosphorylation being a key event. The recent use of high-throughput experimental analyses has revealed that more than 70% of all eukaryotic proteins are regulated by phosphorylation; however, the mechanism of dephosphorylation, counteracting phosphorylation, is relatively unknown. Recent discoveries have shown that many of the protein phosphatases are involved in the temporal and spatial control of mitotic events, such as mitotic entry, mitotic spindle assembly, chromosome architecture changes and cohesion, and mitotic exit. This implies that certain phosphatases are tightly regulated for timely dephosphorylation of key mitotic phosphoproteins and are essential for the control of various mitotic processes. This review describes the physiological and pathological roles of mitotic phosphatases, as well as the versatile role of various protein phosphatases in several mitotic events.

Darina [25.2K]

Answer:

Statement 1.) Both saturated and unsaturated fats.

Statement 2.) Saturated fat

Statement 3.) Unsaturated fat

Statement 4.) Unsaturated fat

Statement 5.) Both saturated and unsaturated fats.

Statement 6.) Saturated fat.

Explanation:

Fatty acids are straight chain carbon compounds of varying lengths. It is an important component of lipid in plant and animals. All fats are known to contain nine calories per gram, therefore can add to the weight of an individual. There are two type of fatty acids which includes:

--> Saturated fatty acids: these are fatty acids that contains no double bonds making it solid at room temperature. They are usually found in animal products such as milk, cheese and meat. They are absorbed in the villi of small intestine after digestion. One of the disadvantages of consuming diet rich in saturated fat is Saturated fats might increase LDL cholesterol levels. These are the bad cholesterol which are affected by inhibiting the LDL receptor activities leading to its increase. This can lead to heart disease conditions.

--> Unsaturated fatty acids: These are fatty acids which may contain one or more double bonds making it liquid at room temperature. They are found in plant oil (omega 6) and fish oil (omega 3). When consumed, they are absorbed in the villi of small intestine and helps maintain a good balance of cholesterol in blood.

e  Ee    Ee
(I can't make it, but this is what you fill in)

As you can see, there's two EE and two Ee. Each still has at least one dominant E, so all are dominant. Your answer is a 100% chance they'll have detached earlobes.
