Advances in technology have enabled scientists and researchers to better study the evolutionary relationships between species. M
padilas [110]

Answer:

Embryology: the study of similarities in embryos of organisms to find common connections

Developmental biology:  the study of life cycles of organisms to find common

Molecular biology: the analysis and comparison of DNA to better understand relationships between species

comparative anatomy: the study of the anatomy of an organism to explain evolutionary similarity

Explanation:

Embryology can be described as the branch of biology in  which studies about the sex cells, the process of fertilization and the development of the fetus or embryo are made. The similarities between the embryos show evolutionary history among different organisms.

Developmental biology can be described as the branch of biology in which studies are made about the processes of growth and developmental procedures about organisms. Organisms belonging to different groups can also show developmental similarities if they have a common ancestor.

Molecular biology is the branch of biology which is related to the study of life on molecular level. At this level, similarities between the genome of organisms can be checked for evolutionary histories.

Comparative anatomy: It is the branch of biology in which organisms are studies based on the similarities and differences in their structures.

The bladder is in the _____ region. a. hypogastric b. right lumbar c. left lumbar d. epigastric
Anastasy [175]

The <u>bladder </u>is in the hypogastric region.

Hypogastric Region- The structures around the pelvic bone are located in the hypogastric area. These include the prostate in men and the womb and ovaries in women, as well as the bladder, a section of the colon and rectum, the anus, and several reproductive system organs.

Bladder- A little above and behind pubic bone in the pelvis, the urine bladder is a muscular sac. The bladder is roughly the size and shape of a pear when it is empty. The kidneys produce urine, which then passes via capillary called ureters and into the bladder. Urination can be restricted and rare because to the bladder's ability to hold pee.

Oh, no... you dropped your study flashcards, and now they're out of order! Put them back into the correct order for a eukaryotic
Vladimir79 [104]

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.

Potassium has a half-life of 12 hours. What fraction of a 100g sample is left after 48 hours
EastWind [94]

Answer:

After 48 hours amount left = 6.25 g

Explanation:

Given data:

Half life of potassium = 12 hours

Total mass = 100 g

Mass left after 48 hours = ?

Solution:

Number of half lives passed:

Number of half lives = Time elapsed / half life

Number of half lives = 48 hours/ 12 hours

Number of half lives = 4

At time zero = 100 g

At first half life = 100 g/ 2 = 50 g

At 2nd half life = 50 g/2 = 25 g

At 3rd half life = 25 g/2 = 12.5g

At 4th half life = 12.5 g/2 = 6.25 g

A farmer is trying to determine why some weeds sprayed with weed killer do not die. to begin a scientific investigation of this
blagie [28]
The first thing that the farmer should do is formulate a hypothesis in which he will make intelligent guesses on what is happening or develop a theory of which would explain what is happening. It is the first step in scientific investigation in order to formulate questions of why weeds that are sprayed does not die. After this, it is only then the farmer should experiment and after that, he should finalize his findings as it is its conclusion to the problem.
