atoms determine the number of valence electrons determine the stability of the atom based on above
Enzymes are the bio-catalysts. Their presence can increase the rate of a reaction. Enzymes are most effective at a particular pH and temperature but can also function over a range of pH and temperature. Thus, correct option is A.
What are Enzymes?Enzymes are the biocatalysts which are responsible for increasing the rate of a chemical reaction. The enzymes increase the rate of a reaction by decreasing the activation energy which is required by the reactant molecules to collide and form products.
Enzymes are found to function over a range of pH, temperature, and solvents. Enzymes work over a range of different conditions. The value of pH and temperature at which enzymes show highest activity is called optimum condition. Below and above this point, enzymes function but the activity will be lesser than that in the optimum condition.
Therefore, A is the correct option. Enzymes are most effective at optimum condition of pH and temperature.

During the replication of DNA:
A. both strands of the DNA molecule act as templates
B. only one strand of DNA acts as a template
C. the cell also undergoes mitosis
D. the reaction is catalyzed by RNA polymerase
Answer:
A
Explanation:
Both strands of the DNA molecule act as templates
Both strands will be divided and then used to make two new DNA strands, each with half of the original
During DNA replication, the two strands of the DNA molecule act as templates. Because the fret has been divided into two pieces, each new DNA strand contains half of the original strand.
What is DNA?DNA, or deoxyribonucleic acid, is the molecule that carries the genetic material required for an organism's growth and operation. DNA has a double helix structure, which is made up of two connected strands that loop around one another to form a twisted ladder.Depending on your parents, half of your genome is inherited from your mother and half from your father. The information molecule is DNA. It stores instructions for the production of larger molecules known as proteins. These instructions are stored within each of your cells and are distributed across 46 long structures known as chromosomes. These chromosomes are composed of thousands of shorter DNA segments known as genes.To learn more about DNA refer to:

Compare and contrast the skeletal body system with immune system
Abstract
In the last two decades, numerous researchers have focused on elucidating the relationship between the skeletal and immune systems with respect to their regulatory mechanisms. It has now become clear that osteoclasts are derived from the same myeloid precursor cells that can differentiate into macrophages and myeloid dendritic cells. In addition, bone and immune cells coexist in the common microenvironment of the bone marrow and are thus influenced by similar mediators. Discovery of a common regulatory mechanism via the receptor activator of nuclear factor kappa-B ligand (RANKL)–receptor activator of NF-κB (RANK)–osteoprotegerin (OPG) axis in both the bone and immune system has not only increased understanding of the fundamental processes of bone homeostasis but has further crystalized understanding of the definitive regulatory correlation between bone and immunity. Moreover, many of the soluble mediators produced by immune cells, including cytokines, chemokines, and growth factors, regulate the activities of osteoclasts and osteoblasts. This increased recognition of the complex interactions between the immune system and bone has led to the development of the interdisciplinary field of osteoimmunology. In this review, we summarize the characteristics of bone cells and the soluble mediators responsible for crosstalk between the skeletal and immune systems. A more complete appreciation of the interactions between immune and bone cells should lead to better therapeutic strategies for diseases that affect either or both systems.

Which statement correctly describes how energy is made in photovoltaic cells and how energy is made in photosynthesis?
A.photovoltaic cells can only make energy that does not need light for photosynthesis can only make energy that needs light.
B.photovoltaic cells in photosynthesis can make energy that need light and energy that does not need light. C.photovoltaic cells need light to make energy by photosynthesis to make energy that needs light and energy that does not need light. D.photovoltaic cells can make energy that need light in energy that does not need light for photosynthesis can only make energy that does not need light
Both photosynthesis and photovoltaic cells need light in order to produce energy, though photosynthesis does have a process that can occur in the absence of light, so option C is correct.
Photovoltaic cells are man-made panels that use solar light to create energy. They do this by taking advantage of the natural ability of some materials to absorb the photons in sunlight and use them to release electrons. The release of electrons generates an electric current which produces energy.
Meanwhile, photosynthesis is a naturally occurring process by which plants and a handful of other organisms produce energy. Photosynthesis also requires the presence of sunlight to function. However, photosynthesis also has a dark phase where the chemical reactions continue despite the absence of light. For these reasons, option C is correct whilst the rest are false.

according to plato, where do souls have to drink before starting their new lives on earth?
According to Plato, the souls of people tend to reincarnation, that is, the souls of each person have had previous lives in which they have developed and have had different experiences.
Thus, as a way to generate an impartiality of the soul, which allows it to start a new life without influences on previous lives, they should drink water from the River of Forgetfulness.
This made the souls unable to remember anything from their previous lives or the adrenal world in which they were before coming back to life.

Alcoholic fermentation
Photosynthesis
Aerobic respiration
Latic Acid Fermentation
Answer:
Running can take many forms, from a leisurely jog to an all-out sprint. But no matter what kind of running you do, your body needs to power itself through respiration. Lighter, long-distance running causes your body to use aerobic respiration, while more intense sprinting and interval training requires anaerobic respiration.

according to the induced fit hypothesis of enzyme catalysis, _____.
Answer:
the binding of the substrate changes the shape of the enzyme's active site
Explanation:
According to the induced fit hypothesis of enzyme catalysis, the shape of the active site of an enzyme changes in response to the binding of a substrate molecule.
What is induced fit hypothesis of enzyme catalysis?The active site, which is the region of the enzyme that interacts with the substrate, adjusts its shape to fit the substrate more snugly. This change in shape enhances the formation of the enzyme-substrate complex, leading to more efficient catalysis and faster reaction rates.
The induced fit hypothesis suggests that the active site is not a rigid structure, but rather, is flexible and dynamic, adapting to the substrate to optimize the reaction.
