Answer:

lactic acid fermentation.

Explanation:

Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.

Answer:

The answer for this question is lactic acid fermentation.

Explanation:

When we exercise, we have a lot of lactic acid already built in the muscles.  This lactic acid needs to be oxidized into carbon dioxide and water. This is the reason why we start to breathe heavily after a workout session, because since we have a built up of lactic acid, the lactic acid now needs oxygen to be broken down.

Answer:When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels back up to normal.

Explanation:

Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place, and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance.

Hope this helps!! :)

the plants have utilized the energy of sunlight to produce glucose (and ultimately other carbohydrates, proteins and fats) and oxygen from water and carbon dioxide.

Answer:

The answer is B

Explanation:

It uses carbon, light, and water but not chemical because it doesn't produce.

Answer:

The answer is B mitochondria

Explanation:

Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria.

Answer:

The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture).

Answer:

B. Extinct

Explanation:

Exctinct means no longer exists.

In this case, fossils provide the proof that exctinct animals species used to exist but no longer do. For example, dinosaurs are the prime example of this.

Answer:

The nutrients that provide energy are commonly referred to as macronutrients (carbohydrates, lipids, and proteins). Carbohydrates and proteins provide a similar amount of energy per gram of food.

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.

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.

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:

Therefore, TCA-GAT  is transcribed to AGU-CUA

Explanation:

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.")
