B. The reactions don't require light to be carried out.
Explanation:
Dark reaction is a light-independent process. This reaction occurs in the stroma of the chloroplast where it utilizes the products of the light reaction. Since this is not directly dependent on light, it is called as the dark reaction.
which option correctly describes the mode of inheritance for sickle cell anemia
recessive, X-linked dominant, X-linked recessive Or dominant
The mode of inheritance for sickle cell anemia is recessive.
Sickle cell anemia is a type of inherited genetic disorder where the blood cells are shaped as sickle or crescent-shaped instead of being oval flat disc-shaped cells. This peculiar structure of the abnormal red blood cells deems them unable to carry sufficient oxygen to the tissues and organs of the body.
To be affected by sickle cell anemia, an individual has to inherit one copy of the sickle cell gene from each parent, irrespective of gender. Thus, it can be also called a type of autosomal recessive disease. The disease is only expressed in the homozygous recessive condition.

if 4 molecules of water are oxidized by the light-dependent reactions, how many molecules of ATP are formed directly as a result?
When 4 molecules of water are oxidized by the light-dependent reactions, six molecules of ATP are formed directly as a result.
What are molecules?A molecule is described as a group of two or more atoms held together by attractive forces known as chemical bonds.
The Adenosine triphosphate (ATP) is described as the source of energy for use and storage at the cellular level. The structure of ATP is a nucleoside triphosphate, consisting of a nitrogenous base (adenine), a ribose sugar, and three serially bonded phosphate groups.
During the light-dependent reaction the ions flow through ATP synthase from the thylakoid space into the stroma in a process called chemiosmosis to form molecules of ATP.

1. A decrease in light intensity means a decrease in the available reactants needed for photosynthesis.
2. A decrease in light intensity means the enzymes that control photosynthesis may denature.
3. A decrease in light intensity means a decrease in the energy required for photosynthesis to take place.
4. A decrease in light intensity means an increase in the energy required for photosynthesis to take place.
Answer:
3. A decrease in light intensity means a decrease in the energy required for photosynthesis to take place.
Explanation:
The greater the light intensity, the more energy supplied to the plant and therefore the faster the light-dependent stage of photosynthesis can occur.
Mia is building a diorama showing the parts of an atom. She wants to better understand the effects of electric forces. An atom is made up of particles called protons, neutrons and electrons
The way dirt sticks to surfaces in our daily lives, such as clothing and walls, is a result of electrostatic forces on fine particle adhesion.
What is the effect of electric forces?Generally, when particle material is electrically insulating, so the electric charge may be kept, electrostatic forces become significant.
Two charges interact with one another to produce electrical forces. The electric force exerted on a single charge in scenarios involving three or more charges is simply the sum of the interactions between that charge and all other charges.
Therefore, Electric force strength is influenced by the electric charge on the particles, as well as their separation from one another.

How does the body respond if the skeletal system does not function properly? I would like a detailed answer please :)
If there is no skeletal system, the person will not be able to move at all or breathe.
Why is the skeletal system so important?The skeletal system not only serves as a support and lever for the movements of the body, it also serves as protection for the internal organs so that in the face of an impact it does not cause them any damage.
Also the thorax, apart from supporting all the thoracic organs and protecting them, will have a function in breathing so that they inflate while the diaphragm contracts. If all this is not done simultaneously, breathing will not be possible and this will be incompatible with life.
As for the skull, there will not be the correct separation of nerves and brain fluids and this will not be sustainable for life either, since a certain support is needed that gives the cerebrospinal fluid to the structures of the central nervous system and the intracranial pressure that also occurs.

The differentiating factor between water and land plants is that the land plants have larger root systems whereas several water plants lack a root system.
What are the roles of plants in shallow water and dry land?Plants that grow in dry areas have xeromorphic traits to reduce transpiration under drought stress.
Reduction in transpiration under drought stress conditions can also be attained through leaf shedding and decrease in leaf number, leaf size, and branching.
The shallow water, abundant light, and nutrient-rich sediment are the ideal conditions for the growth of plants. Aquatic plants then provide food and habitat for many animals such as fish, frogs, turtles, insects and snails.

Why might it be advantageous for a sessile (non-motile) Cnidarian to have radial symmetry?
It is advantageous for a sessile (non-motile) Cnidarian to have radial symmetry. Animal body parts are radially symmetrical and they are arranged along a central axis so each part extends from the center.
Because of having radial symmetry the animal body parts can be identically cut along the central axis. Animals having radial symmetry are incapable of moving and sessile. Radial symmetry helps out to reach every corner of their body parts. Cnidarians contain two tissue layers. The outer layer is called the epidermis. The epidermis is formed from the ectoderm. The inner layer, which is called the gastrodermis, which secretes digestive juices into the inner parts called the gastrovascular cavity. This gastrodermis is formed from endoderm. Cnidarians do not have to contain mesoderm and Hence cnidarians do not have organs.
