<span>A fossil leaf that is made only of carbon preserved between two rock layers is called carbon film fossil.
</span>Characteristic of the carbon film fossils is that they are primarily composed of carbon. The fossil leaf has usually lost <span>internal components (cell walls and internal cell structures ).</span>
Answer:0.8775
Explanation:formula for gene frequency is p+q=1
where p is the dominant allele and q is the recess allele.
Given than p=0.35
P^2=0.35^2=0.1225
q=1-p
q=1-0.1225=0.8775
Answer is 0.8775
Answer:
C) the three-base sequence of mRNA
Explanation:
Three-base sequence of mRNA is called codon. One codon specifies a single amino acid. There are 64 codons in eukaryotic cells and three of them are stop codons (non-coding).
tRNA have three-base sequence called anticodon which is complementary to specific codon. During the process of translation codon and anticodon are paired which leads to addition of amino acid to growing polypeptide chain. Newly added amino acid is carried by tRNA.
<h2>Primates </h2>
Explanation:
Primates are a group of animals has flexible hands and feet, large brains in relation to body size, forward-looking eyes, and arms that can rotate in a circle around the shoulder joint
- Primates include the lemurs,lorises,monkeys,apes and humans
- The order Primates, with its 300 or more species, is the third most diverse order of mammals, after rodents and bats
- The Primates order is divided informally into three main groups: prosimians, monkeys of the New World, and monkeys and apes of the Old World
- All primates have five fingers (pentadactyly), a generalized dental pattern, and a primitive body plan
- Another distinguishing feature of primates is fingernails
- Opposing thumbs are also a characteristic primate feature
- When compared with body weight, the primate brain is larger than that of other terrestrial mammals, and it has a fissure unique to primates that separates the first and second visual areas on each side of the brain
- The eyes face forward in all primates so that the eyes visual fields overlap
- Fossils of the earliest primates date to the Early Eocene Epoch (56 million to 40 million years ago) or perhaps to the Late Paleocene Epoch (59 million to 56 million years ago)
