c. Transcription of one DNA strand results in mRNA, which is a complementary copy of the information in the DNA.

a. The mRNA leaves the nucleus and goes to a ribosome open choices for ranking.

b. The building blocks of proteins, are carried to the ribosome by tRNAsAmino acids.

The process of deoxyribonucleic acod starts with replication to transcription and translation.

Replication involves the formation of a complementary base from a old or template DNA Strand this then serve as a template for transcription.

transcription involves the coping of information on the DNA to an intermediate mRNA ( messanger ribonucleic acid) in the nucleus which then move from the nucleus to ribosome in the cytoplasm where translation occurs.

Translation is the conversion of the information on the mRNA to an amino acid with the help of enzyme transferse ribonucleic acid(tRNA).

Hence the arrangement is from C ---- A-----B.

Answer: Weak.

Explanation:

The complete question is:

Scientists use a substance called Iodine-131 to treat cancer. As Iodine-131 undergoes radioactive decay and emits beta particles, it kill cancer cells. Which fundamental force is being used in this type of treatment?

Well, here we have beta decay.

Beta-decay is when a beta particle (an electron or a positron) is emitted from an atomic nucleus (usually a neutron-rich nucleus). We know that beta decay is a consequence of the weak force or weak interaction (the force responsible for the radioactive decay of atoms)

Then the correct option is the second one, weak.

Answer: The basic tissue structure of the mucosa layer of the alimentary canal consists of:

--> mucous membrane

--> lamina propria

--> muscularis mucosa

Explanation:

The MUCOUS MEMBRANE forms the innermost layer of the alimentary canals which includes the stomach and the duodenum (small intestine) . It's major functions is protection, secretions and absorption. The type of mucous membrane found in the stomach and duodenum is the Columnar epithelial cells. Not numerous gastric glands are situated below the surface in the mucous membrane of the stomach. They consist of specialised cells that secrete gastric juice that aids in the digestion of food. While the duodenal mucosa consists of mucous producing goblet cells. These cells produce a viscous, alkaline mucus that protects against the acidic gastric juices and pepsin. The folding of these mucosal cells (microvilli) provides a large surface area to optimize nutrient absorption.

The LAMINA PROPRIA: This layer separates the mucous membrane and the muscularis mucosa. It is made up of connective tissues which supports the blood vessels that nourishes the inner epithelial layer. In both the stomach and duodenum, digested nutrients are absorbed into the capillaries.

MUSCULARIS MUCOSA: This is made up of thin layer of smooth involuntary muscles. The contraction and relaxation of these muscle layers occurs in waves, which push the contents of the tract onwards. This type of contraction is called peristalsis which occurs in the duodenum. While in the stomach, these muscles allows for the churning motion characteristic of gastric activities.

The breakdown of protein in the presence of enzyme has lower activation energy.

The breakdown of protein in the stomach is achieved with the loss of peptide bonds, and the complex is broken down into amino acids.

The protein is broken down in the digestion at small intestine and stomach. The graph represents the energy of the reaction with the progress of protein degradation.

The energy of the reaction is highest when the protein breakdown activation is processed. The enzyme is the catalyst, that acts in fasting the reaction with the lowering of activation energy.

Thus, the breakdown of protein in the presence of enzyme has lower activation energy.

Explanation:

  You have 20% of adenine. If you have 20% of adenine than you have 20% of thymine, because the amount of adenine and thymine is equal. 20% plus 20% is 40% of adennine and thymine. From 100% DNA bases subtract 40% and you will get 60%. Then divide this by 2 and you will get 30%. 30% of guanine and 30% of cytosine, because their amounts are equal in the DNA stand.

The type of weathering seen in the pictures is mechanical weathering.

Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time by various physical, chemical, and biological processes. It is a fundamental part of the Earth's surface dynamics and plays a significant role in shaping landscapes.

Mechanical weathering involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. It increases the surface area of rocks, making them more susceptible to further weathering.

In natural selection, traits benefit the species and in artificial selection, the traits benefit humans, these are the main difference between natural selection and artificial selection, hence option C is correct.

Natural selection is the procedure by which populations of living organisms adapt and change.  In a population, all individual have different traits, which suggest that all individual shows variation in the population better to adapt.

While as compared to natural selection, is the selection of traits by humans to enhance this trait for their own purpose, In natural selection, traits benefit the species and in artificial selection, the traits benefit humans.

Therefore, natural selection is the adaptation through which, species get benefits and through artificial selection, the traits benefit humans.

DNA with the shortest strand will travel longer than DNA with the longer strand. In electrophoresis, the electricity will cause the DNA to move from one side of the gel to the other side. Shorter DNA strand will have a lower resistance to move in that gel so it can move further.

Explanation:

DNA with the shortest strand will travel longer than DNA with the longer strand. In electrophoresis, the electricity will cause the DNA to move from one side of the gel to the other side. Shorter DNA strand will have a lower resistance to move in that gel so it can move further.

The smallest strand of DNA will move farther than the longest strand. DNA will travel from one side of the gel to the other during electrophoresis as a result of the voltage.

A shorter DNA strand will pass through the gel with less resistance, allowing it to move farther.

The smallest strand of DNA will move farther than the longest strand. DNA will travel from one side of the gel to the other during electrophoresis as a result of the voltage.

A shorter DNA strand will pass through the gel with less resistance, allowing it to move farther.  The publication of On the Origin of Species in 1859, Darwin has typically eclipsed Wallace.

Answer: Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

Explanation:

Brain is composed of brain cells known as nerve cells where as RBC also known as red blood corpuscle is a component of blood.

The brain's neurons are the cells that transmit and receive chemical and electrical messages. They serve as the brain's building blocks and act as information carriers for all of the body's neurons, muscles, and tissues. You can think, feel, move, and take in information with their help.

Erythrocytes, sometimes known as red blood cells, are one of the elements of blood. Our bone marrow continuously produces them. One billion red blood cells can be found in just two or three droplets of blood, which is what gives human blood its recognizable red color. From our lungs, red blood cells transport oxygen to the rest of our bodies. The carbon dioxide is then transported back to our lungs, where it is expelled.


Therefore, the structure of a brain cell differs greatly from red bood cell.
