<h3>ANSWER:</h3>

Black and white are the only two phenotypes of exoskeleton that are exhibited in the population. For example, beetles who have a black color exoskeleton will have a Bb or a BB genotype while beetles with a white exoskeleton will have a bb genotype. B is the dominant allele while b is the recessive allele.

Two phenotypes of exoskeleton are exhibited in the population: black and white. According to the information provided, beetles with the black phenotype can either have a BB or a Bb genotype, while beetles with the white exoskeleton have a bb genotype.

Which of the Caulerpa taxifolia’s traits make it so dangerous to local ecosystem

k0ka [10]

Answer:

Caurepa taxifolia is an invasive species of algae and is listed in the IUCN list of 100 invasive species. 

Explanation:

In is an algae usually found in the pacific ocean. It was earlier used in aquariums as an ornamental species of algae. The dangerously invasive nature overshadows its attractive appearance.

It is inedible and increases in numbers at a surprisingly accelerated rate. The growth of other plants is difficult in areas dominated by the Caurepa taxifolia. The introduction of this algae was in the Meditteranian sea.

Explain in detail how galen, a physician during the middle ages, expanded on hippocrates’ theory of the four humors and explain

Ann [662]

Hippocrates believed that there are four humors in human body which need balance for a healthy being. These were:
Blood, phlegm, yellow bile, and black bile.
Galen expanded the idea of the humors and introduced four temperaments which were these:
choleric (hot / dry), melancholic (cold / dry), sanguine (warm / moist), and phlegmatic (cold / moist).
Another expansion Galen did was that he gave each humor/temperament physical and psychological qualities and said that even the food items have an association with the certain humor, those foods can effect certain humor in certain ways.

The difference between protostomes and deuterostomes is _____. protostomes have only an ectoderm and endoderm protostomes have o

ella [17]

Protostomes develop a mouth first and then an anus. This is the difference between protostomes and deuterostomes.

In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.

In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.

Nezavi [6.7K]

The given question is incomplete, the complete question is:

Oh, no... you dropped your study flashcards, and now they're out of order! Put them back into the correct order for a eukaryotic cell.

a. "Combine the mRNA strand with a ribosome and a tRNA carrying a methionine."

b. "Unwind the DNA molecule near the promoter."

c. "Exit the nucleus to the cytoplasm."

d. "Transcribe the complementary RNA strand."

[Tip: you might want to work out the correct order on a piece of scratch paper before selecting from the options below.]

c - d - b - a

b - d - c - a

c - b - d - a

d - b - c - a

b - d - a - c

Answer:

The correct order would be b, d, c, a.

Explanation:

First unwinding of the molecule of DNA takes place close to the promoter. After that transcription of the complementary RNA strand takes place, then mRNA moves out of the nucleus into the cytoplasm. Ultimately, the combination of ribosome and tRNA carrying a methionine takes place with the mRNA.

The order is based upon the central dogma of the cell. Based on the central dogma concept, the transcription of the mRNA takes place in the first place, which then gets transported out of the nucleus into the cytoplasm in the eukaryotic cell. The unwinding of DNA takes place close to the sequence of the promoter for the process of transcription.

In the promoter region, various transcription factors are present and binding of RNA polymerase takes place with the template strand. The generated mRNA then get transported out of the nucleus into the cytoplasm. Post transcription, translation of mRNA takes place with the assistance of tRNA and ribosome. In the mRNA, the start codon generally codes for methionine because of which the tRNA that carries methionine identifies the start codon, and the process of translation gets initiated.
