It is known as acetabularia acetabulum. An algae that you see in water mostly, its like those mini "lily pads" you pull up from the water. :)
Answer: B. High levels of nitrogen and phosphorus from agriculture runoff, sewage, and etc
Explanation:
i did it off study island
<h2>B) option is false</h2>
Explanation:
All events of cell cycle is regulated by a heterodimeric protein complex called cyclin CDKs, cyclin is the regulatory subunit which binds to CDKs and activate them whereas CDKs(cyclin dependent kinases) is the catalytic subunit where cyclin bound CDKs become active and act as serine threonine kinase and phosphorylate target proteins
The activation of S-Cdk helps prevent the onset of M phase because S phase cyclin CDK complex trigger initiation of DNA replication from pre replication complex and inhibits rebinding of components of pre replication complex
Frequency of an allele = number of desired allele in the population / total number of alleles in the population
Here there are two alleles as 'O' (dominant allele) and 'o' (recessive allele)
Since there are 100 flowers, the total number of alleles is 100 x 2 = 200.
Homozygous flowers have OO alleles while heterozygous have Oo alleles.
O alleles in homozygous flowers = 60 x 2 = 120
O alleles in heterozygous flowers= 30 x 1 = 30
Hence, total O alleles = 120 + 30 = 150
Frequency of O allele = 150 / 200 = 0.75
Igneous rocks are formed/created by the cooling of magma. So if some lava from a volcano cools down it becomes an igneous rock!
I hope this helps you, sorry if this is not what you were looking for!
