Answer:
The division of eukaryotic cell is done through various phase known as cell cycle.
Explanation:
The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:
1) G2 Phase; G2 checkpoint ( Interphase stage)
2) Prometaphase (Mitotic Phase)
3) Anaphase (Mitotic Phase)
4) Telophase (Mitotic Phase)
5) cytokinesis (Mitotic Phase)
6) G1 Phase; G1 checkpoint ( Interphase stage)
After G1 phase there would be again S phase in which DNA replication occur.
Answer:
Articular articular cartilage is very important part of the long bone structure. It is present between the bones at the joints and help in reducing the friction between the joints. the epiphytes is data present at the end of the long bones are usually have a covering of the articular cartilage and it has a very thin layer of cartilage that helps in reducing the friction .
It also act as a shock absorber between the two bones and helps in the transmission of force from one phone to another and divide the force across the skeletal system. It also transmit the force on the bones with low fictional coefficient. The articular cartilage are very susceptible and prone to the injury and it lacks blood vessels and nerves. Articular cartilage is made up of hyaline cartilage and is made up of densely packed extracellular matrix which certain type of specialised cells known as chondrocytes. It is also made up of water , collagen , proteoglycans and glycoproteins .
Answer;
-Our brains fill in gaps in our perception.
-If its been a long time since an event occurred, we might imagine things that did not happen.
Explanation;
-One way that our brain may alter sensory information is by filling in information that is not really there. For example a word in a sentence could have a missing word but we probably assume that word is there and keep reading the sentence.
-Another way is applying already known stuff into new situations. For example we have learned that if a dessert is pink, then it is strawberry flavored. If we saw a bowl of vanilla ice cream with pink food coloring, we may assume it's strawberry ice cream.
<span>It's important to regulate genes so it does nothing unnecessarily. This will help it save energy. Different specialized cells and factors control the making of genes and the way they do it depends on its environment. The regulators can be turned on and off depending on why and how t needs and uses things around it. There are also necessary factors that allow gene regulation. E Coli must regulate the lac gene so it is used properly. If there is lactose around it, it must be switched on to process it. If there is no lactose around, then it must turn off to save energy because there is no reason for it to be in use.</span>
Answer:
A. Redshift and Blueshift
Explanation:
It’s red shift and blue shift, because this only occurs when the frequency of the wave is made longer or shorter due to the movement of the source relative to the observer.
