A geologist uses relative dating methods to guess that a rock is between 1 million and 5 million years old. What is one radioactive isotope the geologist can use to learn the exact age of the rock?
Answer:
Scientists usually use the potassium-argon method to date rocks that are older than about 1 million years. Uranium-238 is also used for radiometric dating. It has a half-life of 4.5 billion years. It decays to produce lead-206.
Potassium-40 is one radioactive isotope the geologist can use to learn the exact age of the rock, by the use of radiometric dating methods.
What is radiometric dating?This is the process through which geologists can easily use to learn the exact age of the rock, it depends upon the natural radioactive decay of some elements such as potassium and carbon.

Radiometric dating is to find the date of the material such as carbon or rocks by labeling the radioactive impurities in a trace amount that is incorporated in it.
Therefore, Potassium-40 is used to know the exact age of the rock.

Instructions: Look at the motion graphs shown below. Match the descriptions here to the coorect graph.
Description a. A car moving at a constant speed stops and then moves in the opposite dorection at the same speed.
Description b. A car moving at a constant speed stops and then moves faster in the same diresction.
Description c. A car moving at a constant speed changes to a higher constant speed
Description d. A car moving at a constant speed changes to a lower constant speed.
Answer:
A-2
B-4
C-1
D-3
Explanation:
In description A, the car is first moving at a constant speed, which means it will have a constant slope. Then, it stops, which causes a slope of 0. Finally, it moves in the opposite direction, which will cause a negative slope. The second graph has a positive, zero, and negative slope; therefore, it fits A.
Description B has a constant slope, a zero slope, and a higher slope. Graph 4 goes up normally, then stops, and finally goes steeper. This fits description B.
Description C has a constant and then a higher slope. Graph 1, increases steadily and then sharply increases; which fits C.
Description D has a constant and then a lower slope. Graph 3 increases fast but then flattens, which matches the slopes in the description.

why is crossing-over important?
Answer:
Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over
Explanation:
Answer: Crossing over is very important.
Explanation:
When crossovers acour in genectics they add more verietty to the next generations.
In pea plants the trait for being tall (T) is dominant over the trait for being short (t) and having green peas (G) is dominant to having yellow peas (g).

Which category of gymnosperm is thought to have given rise to flower-bearing plants?
Select one:
a.
Cycadophyta
b.
ginkgophyta
c.
Coniferophyta
d.
gnetophyta
Answer:
d. Gnetophyta
Explanation:
Gymnosperms represent a group of "naked seed" plants which includes, among others, Cycads, Conifers and Gnetophytes. It has been proposed that Angiosperms or flowering plants, probably evolved from Gnetophyta about 150 million years ago. Gnetophyte is a group of Gymnosperms composed of only three living genera: Ephedra, Welwitschia and Gnetum. In Gnetum and Ephedra plants, researchers documented a regular process of double fertilization, which is a distinctive feature of Angiosperms. This important observation has been used to propose that Angiosperms evolved from Gnetophyta.
Answer:
Gnetophyta
Explanation:

ATG - CCG - AAT - TCG
Answer:
AAG GGU CUA AAA
it's U because RNA contain Uracil instead of Thymine
Answer:
AAG - GGU - CUA - AAA
Explanation:
This happens because in the RNA synthesis, Thymine is present in Uracil giving it a U symbol. The conversions between the bases go between Cytosine and Guanine, or Thymine (Uracil) and Adenine. Whenever you switch to the other strand, it becomes the opposite base for the other strand so they fit together perfectly in the chromosome or chromatid. Example: C - G contain opposite characteristics that fit so they only go together, Adenine or Guanine will not ever be present with either of those bases.
what does a microscope enable people to do
A microscope enables people to magnify things up close that you cannot see with the human eye. Many people have found extraordinary things through the telescope, up to 6,500 times up close (world record microscope). They are used in almost every research center.
