<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation.
The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>
base on their characteristics they share
Answer:
DNA sequence from left to right
T G A G G A C T T
Explanation:
There are four DNA nitogenous base they include thymine, guanine, cytosine and Adenine. The Nitrogenous bases are complementary that is Adenine is complementary to thymine and cytosine is completely to quanine and they both can replace each other in this manner A-T,C-G and it means that Adenine can pair with thymine and cytosine can only pair with guanine. DNA is known as Deoxyribonucleic acid. DNA sequencing are shown usually from the 5' end to the 3' end . The sense strand in DNA is used in DNA sequences and also it has the antisense strand and also called the coding strand and the non-coding strand are information are contained in the sequence
Answer:
a. Fluid intelligence
Explanation:
Cattell-Horn's theory of fluid and crystallized intelligence suggests that intelligence is composed of a series of different skills that interact and work together to produce general individual intelligence.
<u>
Fluid intelligence</u> implies being able to think and reason abstractly and solve problems. This ability is considered independent of learning, experience and education. It is basically configured by primary skills such as induction, deduction, relationships and figurative classifications, breadth of associative memory and intellectual speed, among others. It reaches its maximum splendor in the early twenties and tends to decrease in parallel to the aging and deterioration of neurons. This ability can be measured from tests that measure the biological potential of the individual to learn or acquire knowledge.
