Option D is correct, I believe that option A is wrong because in meosis 1 sister chromatids are together option B is wrong because homologous chromosomes are in meiosis 1 not 2 option C is wrong because 4 sex cells are produced in the process of meosis 2
It's some change in the conditions around the organism, which the organism can detect and respond to. A change in temperature, more light, or something physically poking the organism are examples.
Answer:Radiometric dating allows us to indirectly date fossils up to billions of years old based on minerals in surrounding volcanic strata. The correct option is D.
Explanation:
Radiometric dating was first used by geologist after being published by Bertram Bollywood in 1907. During volcanic eruption, some minerals ( carbon) are trapped within the volcanic strata. These minerals are made up of radioactive isotopes which are unstable as they form decay products with a known constant rate of decay. This enables them to :
- access information about the absolute age of rocks,
- date a wide range of natural and man-made materials
- know even the age of earth. I hope this helps. Thanks
Answer:
Behavioral responses in organisms require communication between an organism and its environment (option C).
Explanation:
The behavior of an organism depends on the function of relationship with the environment that surrounds it, and the way to respond to the diverse stimuli that are in this environment.
Behavioral responses always occur as a result of the interaction between the physical environment and other living organisms. This interaction triggers a series of stimuli that are perceived by the senses and processed by each organism, developing an appropriate response to each of them.
