What is an amniotic egg?
Answer: The amniotic egg was an evolutionary invention that allowed the first reptiles to colonize dry land more than 300 million years ago. Fishes and amphibians must lay their eggs in water and therefore cannot live far from water. ... Within the chorion is the amnion, the membrane for which the amniotic egg is named.

how do genes create traits in a organism
Answer:
Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color.

O A. DNA ligase
O B. Restriction enzymes
O C. Antibiotics
O D. PCR
Mark for review (Will be highlighted on the review page)
Si

о
Answer:
O B. Restriction enzymes
Explanation:
Restriction enzymes has the ability to recognize specific DNA sequences and cut them in a specific manner in order to produced by the bacteria as a defense mechanism against foreign DNA containing substance such as viruses etc. This restriction enzyme is also called restriction endonucleases. This is a cloning tool that bacteria produced naturally in order to defend itself from the infection of virus.

What is the main reason to put a telescope in space?
A.
It is much closer to the stars.
B.
It can receive star light that cannot reach Earth.
C.
Light reaching it is not affected by the movement of air.
D.
It can detect objects behind the moon.
Answer: D
Explanation:
The main reason we put telescopes into space is to get around the Earth's atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.
Protein synthesis consumes four high-energy phosphate bonds per added amino acid. Transcription consumes two high energy phosphate bonds per added nucleotide. Calculate how many protein molecules will have been made from an individual mRNA at the point when the energy cost of translation is equal to the energy cost of transcription. Assume that the nucleotides in the coding portion of the mRNA constitute 5% of the total that are transcribed.
Answer:
30 protein molecules per mRNA molecule
Explanation:
In this problem, it is necessary to have into account that the transcriptional process requires six (6) phosphate bonds to synthesize one (1) codon (i.e, each three nucleotides), and also discards 95% more energy to make mRNA, it means 19 times this amount of energy >> 6 x 19 = 114 bonds. In consequence, transcription requires 120 phosphate bonds (6 + 114 = 120), while translation requires four (4) phosphate bonds per codon. From this deduction, it is possible to find the number of protein molecules synthesized with regard to the energy cost of the translation process and the transcriptional process >>> 120 bonds (transcription) /4 bonds (translation) = 30 protein molecules.

Which process releases the highest amount of energy?
Answer:
glycolysis
Explanation:
In the process of glycolysis only 2 molecules of ATP are produced. Maximum energy is released, when the reduced coenzymes produced in the process of Krebs cycle are oxidised in the process of oxidative phosphorylation in electron transport chain.

Explanation:
this type of consistent adaptation between two species is known as
Answer:
Symbiosis or Mutualism: When two species live together in a close association that is helpful to both species, the relationship is known as symbiosis. The oxpecker bird and the rhinoceros exhibit this relationship. The oxpecker receives protection and obtains food from the ticks and other pests infesting the rhino’s skin.

How did the crickets lose their ability to chirp?
Answer:
By a mutation that altered the shape of their wings, making them incapable of producing the chirping noise. The feat was achieved over less than 20 generations, a mere evolutionary blink of an eye, and, with the crickets living just a few weeks, a very rapid process.

What is the argument against taking persistent vegetative state patients off of life support?
Answer:
An argument could be that there have been many instances where people on life support or in a vegatative state have 'woken' up and gotten better after many years. So, taking someone off life saving machines could be taking away their chance of getting better and their chance of surviving. Since the person is not dead, some may even see it as murder.

your slide is in focus but you cannot see anything, what maybe the possible problem
Answer:
The correct answer would be - using a lens that is too high powered and thus you may be too focused on the specimen.
Explanation:
The possible scenario for this case where the slide is in focus but can not see anything could be either specimen is not under the lense or too focused on the specimen by using a very high-powered lens.
In a very high-powered lens, the lens becomes over-focused and the specimen does not look in the field of view of the lens, in such case, an individual should ower the power of lense.
