Change TCA-GAT from DNA into mRNA
Answer:
AGU-CUA
Explanation:
An mRNA sequence is made using a DNA sequence as a template. The sequence is dictated by complementary base pairing.
DNA uses the bases A, T, C and G. A is complementary to T and G is complementary to C.
RNA uses the bases A, U, C and G. A is complementary to U and G is complementary to C.
When transcribing DNA to RNA:
C is paired with GG is paired with CA is paired with UT is paired with ATherefore, TCA-GAT is transcribed to AGU-CUA

Fossils provide a record of animals that are ___ or no longer living
A. Petrified
B. Extinct
C. Modern
Answer:
B. Extinct

Answer:
c. three amino acids
Explanation:
i know this from my exam in fifth grade. your welcome ;)
An mRNA is made up of the 4 nitrogenous bases A,U,C and G where the thymine is replaced by U for uracil. An mRNA molecule is made up by a codon of three amino acids.
What is amino acid ?An amino acid is made up by the acidic as well as basic group where the acidic group is carboxylic acid and the basic group is amine group.
A codon is made up by the three amino acids where the three of the amino acids together called as codon makes up a nucleotide together and the molecule it codes for makes a long chain of proteins together making up the structure of the desired machinery as per signals and the mechanisms that are assigned to it.
A codon makes up the together the amino acid and then the chain and together it makes up the protein where the long polypeptide makes up the structure that is tertiary in nature.

Seafood Watch recommends which seafood _______.
a. to buy or avoid
b. to catch and sell
c. to harvest sustainably
d. is safe to eat
Answer:
a
Explanation:
to buy or avoid
Seafood Watch recommends which seafood to buy or avoid. Thus, option A is correct.
What is seafood?Seafood is food obtained from the sea. Unsustainable fishing methods, such as dragging and dynamite fishing, entrap or kill various species that are not necessarily targeted by the fishing industry. By identifying varieties of seafood that have been caught sustainably, Seafood Watch promotes them over those that have not.
The theory is that since only fisherman who employ sustainable practices are financially rewarded, they will outperform rivals. Based on rigorous scientific standards for environmental sustainability, our Seafood Watch program assigns grades to seafood collected or raised all around the world.
Our suggestions can be used by customers and business owners to locate seafood that has been farmed sustainably. Numerous species are included in the exhaustive list, along with information about where in the water they were caught—from the wild or from farms—and how they were harvested.
Therefore, Seafood Watch recommends which seafood to buy or avoid. Thus, option A is correct.

Describe each of the following:
Sickle Cell Anemia
Diabetes
Acne
HELP!!
Answer:
1. Sickle cell anemia is an inherited red blood cell disorder in which there aren't enough healthy red blood cells to carry oxygen throughout your body. Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons.
Treatments: Blood transfusion
Symptoms: Pain
2. Diabetes is the condition in which the body does not properly process food for use as energy. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies.
3. Acne is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It causes whiteheads, blackheads or pimples. Acne is most common among teenagers, though it affects people of all ages.

up to about three thousand million years ago there was no oxygen in Earth's atmosphere today about one-fifth of the atmosphere is oxygen gas. suggest what caused this change???
pls help
Answer:
Oxygen makes up about one-fifth the volume of Earth's atmosphere today, and is a central element of life as we know it.
But that wasn't always the case. Oxygen, although always present in compounds in Earth's interior, atmosphere, and oceans, did not begin to accumulate in the atmosphere as oxygen gas (O2) until well into the planet's history. What the atmosphere was like prior to oxygen's rise is a puzzle that Earth scientists have only begun to piece together.
Earth coalesced a little more than 4.5 billion years ago from bits of cosmic debris. Liquid oceans existed on the planet almost from the beginning, although in all likelihood they were repeatedly vaporized by the massive meteorites that regularly clobbered the planet during its first 700 million years of existence. Things had settled down by 3.8 billion years ago, when the first rocks that formed under water appear in the geologic record. (They exist in what is now southwest Greenland.)
If Earth had water, it must have had an atmosphere, and if it had an atmosphere, it must have had a climate. What was Earth's early atmosphere made of? Nitrogen (N2), certainly. Nitrogen makes up the bulk of today's atmosphere and likely has been around since the beginning. Water vapor (H2O), probably from volcanic emissions. Carbon dioxide (CO2), also emitted by volcanic eruptions, which were plentiful at that time. And methane (CH4), generated inside the Earth and possibly also by methane-producing microbes that thrived on and in the seafloor, as they do today.
Carbon dioxide, water vapor, and methane played an important role in Earth's subsequent development. Four billion years ago, the Sun was 30 percent dimmer, and therefore colder, than it is today. Under such conditions, Earth's water should have been frozen, yet clearly it wasn't. The water vapor, carbon dioxide, and methane acted as greenhouse gases, trapping heat and insulating the early Earth during a critical period in its development.
Of oxygen, meanwhile, the early atmosphere held barely a trace. What did exist likely formed when solar radiation split airborne molecules of water (H2O) into hydrogen (H2) and oxygen (O2). Hydrogen, a lightweight gas, would have risen above the atmosphere and slowly been lost to space. The heavier oxygen gas, left behind, would have quickly reacted with atmospheric gases such as methane or with minerals on Earth's surface and been drawn out of the atmosphere and back into the crust and mantle. Oxygen could only begin to accumulate in the atmosphere if it was being produced faster than it was being removed'—in other words, if something else was also producing it.
That something was life. Although the fossil evidence is sketchy, methane-producing microbes may have inhabited Earth as long ago as 3.8 billion years. By 2.7 billion years ago, a new kind of life had established itself: photosynthetic microbes called cyanobacteria, which were capable of using the Sun's energy to convert carbon dioxide and water into food with oxygen gas as a waste product. They lived in shallow seas, protected from full exposure to the Sun's harmful radiation. (To learn more about these organisms and the fossil evidence for them, watch the accompanying video "Early Fossil Life.")
