Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
Answer:
Recent advances in medical biotechnology have increased researcher's knowledge of molecular events of Cancer and have created new hopes in early diagnosis and treatment of cancer. Changes in the genome and proteome of the cells disturb the normal cellular control mechanisms.
Explanation:
The correct option is (C) The neuron’s membrane voltage becomes more positive.
The resting neuron has a voltage across its membrane which is called the resting membrane potential. There is a concentration gradient of ions across the membrane when the neuron is in the resting state.
Inside the membrane the concentration of K⁺ and organic anions are more. Outside the membrane the concentration of Na⁺ is more. The membrane is much more permeable to K⁺ than Na⁺ .
The cell’s inside is more negative than the outside when the membrane is hyperpolarized. In neurons the resting membrane potential is close to the equilibrium potential for K⁺.

Because we control them both in the same direction so if we where like some lizards that move each eye individually then we would see two images
Answer:
Cacti
Explanation:
The well know desert plant Cacti have been a very interesting speciman in terms of survival and its adaptation to its enviornment in order to succeed in the game of survival.
- In order to maintain the moisture within the plant, its leaves are in the shape of needles which can lead to less water evoporating from the plant.
- The inners of Cacti have been modified to store water for prolonged periods of time in order to survive the long periods of drought and lack of water.
- The structure and outer skin of the Cactus has been able to help them once again maintain water levels within itself as traits such as waxy and thick skin cover the entirety of the plant.
