What role do cell membranes and protocells play in the "RNA" world?

Answers

Answer 1

Answer:

reibosome

Explanation:

Reibosome is a large molecular complex that assmebles proteins.

Answer 2
RNA carries out a broad range of functions, from translating genetic information into the molecular machines and structures of the cell to regulating the activity of genes during development, cellular differentiation, and changing environments. RNA is a unique polymer.

Role of Cell membranes and Protocells:

Messenger RNA (mRNA) carries the protein blueprint from a cell's DNA to its ribosomes, which are the "machines" that drive protein synthesis. Transfer RNA (tRNA) then carries the appropriate amino acids into the ribosome for inclusion in the new protein.Protocells are thought to have facilitated the reproduction of RNA and therefore the exchange of genetic information at a time before the advent of DNA and proteins.

SERIOUS ANSWER PLZ Which statement describes how energy is connected to photosynthesis and cellular respiration?

Question 10 options:

Energy is released during both photosynthesis and cellular respiration


During photosynthesis energy is released, but during cellular respiration energy is absorbed and stored


Energy is absorbed and stored during both photosynthesis and cellular respiration


During photosynthesis energy is absorbed and stored, but during cellular respiration energy is released

Answers

Answer:

During photosynthesis energy is released, but during cellular respiration energy is absorbed and stored

Explanation:

During photosynthesis energy is absorbed and stored, but during cellular respiration energy is released. This way they both are connected. The correct option is D.

What is cellular respiration?

Cellular respiration is a sequence of chemical processes that disintegrate glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.

Cellular respiration consists of three major steps: glycolysis, the citric acid cycle, and oxidative phosphorylation.

Photosynthesis converts light energy into chemical energy stored in glucose, and cellular respiration uses that energy to build ATP, which performs life's functions.

Furthermore, the photosynthesis reactants CO2 and H2O are cellular respiration products.

Thus, the correct option is D.

COMPLETE THE COMMON COLD CARD. USE THE FLU CARD AS A GUIDE

Answers

what i’m so confused-

Answer: Look below i hope it helps=3

Symptums: Runny or stuffy nose

• Cough (mild)

• Fatigue (sometimes)

• Sneezing

• Watery eyes

• Sore throat

• Headaches (rarely)

• Aches and pains

How it spreads: Viruses that cause colds can spread from infected people to others through the air and close personal contact. You can also get infected through contact with stool (poop) or respiratory secretions from an infected person.

Treatment: There's no cure for the common cold. Antibiotics are of no use against cold viruses and shouldn't be used unless there's a bacterial infection. Treatment is directed at relieving signs and symptoms.

Preventation: Image result for what is the prevention of a common cold

You can help reduce your risk of getting a cold: wash your hands often, avoid close contact with sick people, and don't touch your face with unwashed hands. Common colds are the main reason that children miss school and adults miss work.

a cross between a homzygous tall plant and homzygous short plant would predict that the offspring had: A the same genotype as one of the parents B a phenotype that was different from that of both parents C a genotype that was different from that of both parents D the same genotype as both of the parents

Answers

Answer:

C

Explanation:

The correct answer would be a genotype that was different from that of both parents.

Let us assume that the allele for height is A (for tall) and a (for short). Homzygous tall plant would have the genotype AA while homzygous short plant would have the genotype aa. Crossing both genotypes:

                AA   x   aa

             Aa   Aa   Aa   Aa

All of the offspring, even though have the same phenotype as one of the parents, have unique genotype from either of the parents. While the parents are AA/aa, the offspring are Aa.

The correct option is, therefore, C.

Why do soft sounds do less damage to your ears than loud sounds

Answers

Well loud sounds tend to hurt the ear drum and can cause hearing issues because of how strong the vibration is and soft sounds don’t have a strong vibration which means it doesn’t have any effect on the ear drum

Answer:

"The damage done by noise depends mainly on how loud it is and on the length of exposure. The frequency or pitch can also have some effect, since high-pitched sounds are more damaging than low-pitched sounds. Noise may tire out the inner ear, causing temporary hearing loss."

Explanation:

During transcription, a specific DNA sequence is used as template to synthesize a specific RNA sequence, usually a messenger RNA (mRNA). During this process (transcription), Uracil (U) bases replace Thymine (T) bases. Transcription has three stages: initiation, elongation and termination. Subsequently, the resulting mRNA is used to synthesize a protein, in a process known as translation.

Photosynthesis uses all of the following except
to make food.
carbon dioxide
O light energy
O chemical energy
water


is it’s A?

Answers

Answer:

No I think its C

Explanation:

Photosynthesis is a process that takes place due to water, sunlight, carbon dioxide and creates oxygen.

All the green plants carry out the process of photosynthesis in the presence of sunlight, the carbon dioxide, and water.  

Thereby releasing oxygen and energy. The first organism that evolved to make photosynthesis was the blue-green algae and later on, cyanobacteria evolved which lead to the origin of oxygen on the earth.Thus the photosynthesis is a process that results when all three are processes by the plants.  

Giving out the chemical energy in the form of sugar and air to breathe. Hence the correct option is C.
