Answer: b, d

Explanation:

Most of the time, a cholecystectomy is done to treat gallstones and the problems they cause.

Large stones can be split with a laser, making laparoscopy easier to solve. An incision into the bile duct at the site of the stone, known as a choledocholithotomy, can be used to remove the stone during surgery if either of these methods fails.

The procedure known as endoscopic retrograde cholangiopancreatography, or ERCP, is used to diagnose and treat conditions affecting the pancreas, liver, gallbladder, and bile ducts. It uses an endoscope, a long, flexible, lighted tube, in addition to X-rays.

The experiment carried out by Avery, MacLeod, and McCarty in 1944 established that DNA is the genetic material that carries genetic information. This experiment was conducted on the bacterium Streptococcus pneumoniae, which is a pathogen that causes pneumonia in humans.

This bacterium can exist in two forms, a rough strain and a smooth strain. The S strain is surrounded by a polysaccharide capsule, while the R strain does not have a capsule. When mice were injected with the S strain, they developed pneumonia and died.

On the other hand, the mice injected with the R strain were healthy.The researchers used enzymes to degrade proteins, RNA, and DNA from the heat-killed S strain. They then added the three enzymes to the living R strain and found that the transformation still occurred, indicating that none of the enzymes destroyed the transforming ability.

They then repeated the experiment with different enzyme combinations and found that when DNase was added to the living R strain, the transformation did not occur. This finding led them to conclude that DNA is the genetic material that carries genetic information.

Therefore, the fact that the transforming capacity of the IIIS cell extract was not abolished by treatment with RNase proves that RNA does not function as the genetic material in the IIIS cells (Diplococcus pneumoniae). Hence, option (D) is the correct answer.

This experiment provided important evidence that DNA is the genetic material that carries genetic information and paved the way for future genetic research.

Photosynthesis occurs in the chloroplast .

What is chloroplast?

A chloroplast is a type of membrane-bound organelle known as a plastid that performs photosynthesis primarily in plant and algal cells. The photosynthetic pigment chlorophyll absorbs sunlight energy, converts it, and stores it in the energy-storage molecules ATP and NADPH while liberating oxygen from water in the cells.

The ATP and NADPH are then used to create organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts also perform a variety of other functions in plants, including fatty acid synthesis, amino acid synthesis, and immune response. A chloroplast is distinguished by two membranes and a high concentration of chlorophyll.

Hence, photosynthesis occurs in the chloroplast

Answer:

The half-life of a substance is the amount of time it takes for half of that substance to decay. However, after two half-lives, half of the half remaining will decay, leaving you with one quarter of the original substance.

So, after 1 million years you will have 50% of the original substance remaining.

And, after 2 million years you will have 25% of the original substance remaining.

After 3 million years you will have 12.5% of the original substance remaining.

And after 4 million years you will have 6.25% of the original substance remaining.

The statements regarding enzymes that is NOT true is option A. Enzymes increase the kinetic barrier.

Enzymes, like other catalysts, don't change the substrate-product equilibrium position. Enzyme-catalyzed reactions, in contrast to chemical reactions that are not catalyzed, exhibit saturation kinetics.

Note that Proteins called enzymes aid in accelerating metabolism, or the chemical reactions in our bodies. Some substances are built, while others are deconstructed. Enzymes are a component of all life. Enzymes are produced by our bodies on their own.

Therefore, Instead of raising the kinetic barrier, enzymes lower it (the statement "Enzymes increase the kinetic barrier" is a false statement and is the correct answer choice here). Enzymes lower the activation energy (the claim that "Enzymes speed up reactions by lowering the energy of activation" is accurate and correct), are not consumed in reactions, and have no impact on a reaction's thermodynamics.

Answer:

Move in and out of the cell evenly

Explanation:

In the passive and active transport, the solute move from lower concentration to higher concentration. In the passive transport cellular energy is not required while in active transport, cellular energy is required.

But, when the concentration of molecules are equal on both sides of a membrane, even though the movement of molecules does not stop and molecules keep their movement in and out of the cell evenly.

Hence, the correct answer is "Move in and out of the cell evenly".

Merton's classic experiments that compared the tension development between a voluntary maximal contraction and an electrically induced maximal contraction showed no difference.

The maximal force-generating capacity of a muscle or group of muscles in humans is called maximal voluntary contraction.

Maximum voluntary isometric contraction is an important method with high reliability and is used to measure and evaluate muscle strength.

Electrically induced maximal contraction are muscle contractions produced by the application of electrical current to activate peripheral motor nerves that innervate a targeted muscle. Contraction of muscles takes place when applied electrical current depolarizes the axonal membranes.

Social science intersects with marine science because human behavior causes a lot of issues with the ocean.The correct option is B.

The ocean is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water, making Earth an ocean world. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided.Distinct names are used to identify five different areas of the ocean: Pacific , Atlantic, Indian, Southern, and Arctic.

Seawater covers approximately 361,000,000 km² of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.Pollution of water by human activities makes the marine science intersect with social science.

Hemipteran insects, also known as true bugs, whose food sources already contain dissolved small molecules. This insects feed on

plant sap or animal blood,

Animal blood contain a variety of organic compounds such as amino acids, sugars, and vitamins that are necessary for their growth and development.

Unlike other insects that have to synthesize these molecules themselves, hemipterans can directly absorb them from their food source.

This unique feeding strategy has allowed hemipterans to evolve specialized mouthparts that can pierce through plant or animal tissues and suck up the liquid inside.

As a result, hemipterans have diversified into over 50,000 species with various ecological roles, from crop pests to predators of other insects.
