What is photosynthesis?Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. Photosynthesis produces oxygen as a by-product. It's made at the light stage. Several factors influence the rate of photosynthesis.
Because the amount of light and temperature are optimal at point C, more oxygen is created.
As the light intensity rises, so does the rate of photosynthesis. For photosynthesis, most plants require red and blue light wavelengths. Photosynthesis is a regulated process involving enzymes. The temperature has an impact on enzyme-controlled processes. The rate of photosynthesis is low at dawn due to the low temperatures. Due to the enhanced rate of photosynthesis at sunset, the temperature is at its optimum, resulting in a high oxygen rate.

Which best describes the chemical reaction taking place?
Answer:
Hydrolysis of disaccharides
Explanation:
The correct option is (C).
This statement correctly describes a chemical reaction. Chemical reactions involve the breaking of existing chemical bonds in the reactant molecules and the formation of new chemical bonds to produce the products. During a chemical reaction, the arrangement of atoms is rearranged, resulting in the formation of different molecules with new chemical properties. The breaking and formation of chemical bonds involve the transfer or sharing of electrons between atoms, leading to the creation of new substances.
In a chemical reaction, reactant molecules are consumed and transformed into products. The products of a chemical reaction are the substances that result from the rearrangement of atoms in the reactants. Reactants do not "come out" of a reaction unchanged; instead, they are converted into products.
In chemical reactions, energy may be released or absorbed, depending on the specific reaction and the nature of the reactants and products involved. Some reactions release energy in the form of heat (exothermic reactions), while others absorb energy from the surroundings (endothermic reactions). The release or absorption of energy depends on factors such as bond energies and reaction conditions.
In a chemical reaction, reactants are the starting materials that undergo chemical changes to produce products. Products are the substances that are formed as a result of the reaction. Reactants are transformed into products during the course of the reaction, but products do not "go into" the reaction as starting materials.

A parasitic bacteria contaminated her food.
A mutualistic bacteria infected her digestive system.
A commensalistic organism is now living in her intestine.
A predatorial organism is consuming her natural bacteria
Answer:
A parasitic bacteria contaminated her food.
Explanation:it has to be parasitic for you to have those symptoms therefore its A
Answer:
A parasitic bacteria contaminated her food.
Explanation:
Parasitic bacteria like Clostridium botulinum or salmonella cause food poisoning. The symptoms of food poisoning appear within a few hours of food ingestion or may be after 6 to 10 days. All the symptoms listed here like nausea, fever, and diarrhea occur due to food poisoning. It is clear that she is suffering from food poisoning and since these bacteria caused problems to Arianne without benefiting her in anyway, they are considered as parasites.
Also, mutualistic bacteria are the ones which live in the body of host and provide certain benefits to the host, a commensalistic organism is the one which gets benefits from the host without harming the host, a predatorial organism on the other hand kills the another organism in order to get benefits but in the question nothing like that is happening to Arianne so all these options are incorrect.

(1) store food to be used during early development
(2) attract pollen to be used during development
(3) take in light energy to be used during photosynthesis
(4) produce chlorophyll to be used during photosynthesis
Answer:
the main function of a plant's seed is reproduction to keep it in existence. So, that makes the answer (3) Take in light energy to be used during photosynthesis.
Explanation:
The primary function of a plant's seed is to store food for the embryo's early development. Seeds consist of an embryo, seed coat, and endosperm, with the latter providing the necessary nutrients.
A main function of a plant's seed is to store food to be used during early development. This stored energy and nutrients are critical for the growth of the embryo within the seed. Within flowering plants, these resources can be found in the form of the endosperm or sometimes within the cotyledons, depending on the type of plant.
Seeds have three main parts: the embryo, the seed coat, and the endosperm or cotyledon. The embryo is the young plant itself, the seed coat provides protection, and the endosperm or cotyledons serve as a food reserve. The seed effectively allows a new plant to have a head start in life, providing protection, nutrients, and a mechanism for dormancy, enabling germination when conditions are optimal for growth.

Why can’t cellular respiration occur without photosynthesis?
Answer:
Because photosynthesis makes Glucose and cellular respiration breaks down the glucose into Carbon Dioxide and H20 (Water). 5.0.
Explanation:
Photosynthesis and cellular respiration are interconnected processes. Photosynthesis uses light energy to create carbohydrates and oxygen while cellular respiration uses these carbohydrates and oxygen to release energy. These processes have a cyclical relationship enabling energy conversion.
Explanation:Cellular respiration cannot occur without photosynthesis because of the interdependence of the two processes. Photosynthesis in plants absorbs light energy to create carbohydrates (like glucose) in chloroplasts and releases oxygen as a byproduct. Cellular respiration, on the other hand, involves the breakdown of these carbohydrates using oxygen in the cytoplasm and mitochondria of cells to release energy.
During photosynthesis, with the help of an enzyme known as RuBisCO, CO₂ reacts with an organic compound called RuBP to form a three-carbon molecule of G3P which, after three cycles, leaves the cycle to become a part of a carbohydrate molecule. These carbohydrates are then used as critical starting material for cellular respiration process. The binary synergy between photosynthesis and cellular respiration enables the cyclical conversion of light energy into chemical energy usable by organisms.
To show this in an equation form:
During photosynthesis - 6CO₂ + 6H₂O --> C6H12O6 + 6O₂ (glucose and oxygen are produced).
During cellular respiration (the reverse process) - C6H12O6 + 6O₂ --> 6H₂O + 6CO₂ (water and carbon dioxide are created).

Which of the following two events occur to create a sea breeze? Select all that apply. Warm air rises on the ocean and moves toward the land to cool Warm air rises on land and moves toward the ocean to cool Cool air moves from the ocean to be warmed by the land Cool air moves from the land to be warmed by the ocean
Answer:
Warm air rises on land and moves toward the ocean to cool
Cool air moves from the ocean to be warmed by the land
Explanation:
The land heats up faster than the oceans during the day. This is because water has a high heat capacity and takes more energy to raise its temperatures by one degree (even in comparison to land). Therefore land heats up the air above it faster than the oceans. The air mass over land rises due to drop in density. The cooler and denser air mass above the oceans moves towards land to replace the rising warm air. This creates a cool breeze felt on land during the day as the cool air rushes in.

Answer:
A. Endocrine
Explanation:
The endocrine system is a collection of glands that produce the hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among all the other things
Endocrine system is the human organ system that is made up of glands and hormones.
Option A
Explanation:
The "endocrine system" is responsible for secretion of hormones inside the body and it is made up of endocrine glands such as thyroid glands, pituitary glands, pineal gland, adrenal gland, pancreas, ovaries and testes. These glands releases hormones into the blood to target organs which are situated at a distance or into nearby tissue to target nearby cells or to target self. Endocrine glands works by forming negative and positive feedback loops to regulate the proper functioning and effect of the hormone on the target organ or cells and for control the production of hormone from the glands itself.
in general, characteristics that help an organism survive and reproduce become more common in a population over time. what mechanism of evolution cause this change?
Answer:
Natural selection.
Explanation:
Natural selection means that those with good phenotypes are more likely to survive and reproduce. On the other side of the same coin, organisms with less beneficial characteristics are less likely to survive. Because of this, they can't pass their genetic information down, making it less common, and vice versa.
Natural selection is characteristics that help an organism survive and reproduce become more common in a population over time.
Who proposed the theory of natural selection?
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species

B. green algae don't have chloroplasts and absorb their food rather that perform photosynthesis.
C. green algae don't have vascular tissue and must absorb nutrients directly from the environment.
D. land-based plants breath in carbon dioxide while green algae consume oxygen.
Answer:
The correct answer is option C.
Explanation:
Green algae lack the vascular tissues, that is they do not have phloem or xylem for transporting water and nutrients throughout their bodies. They have a thalloid that means they do not have a body divided into root stem and leaves. The thalloid body helps in absorbing nutrients from surroundings.
The land-based plants have xylem and phloem (vascular tissues) to transport water, nutrients, and minerals throughout the body.
Thus, the correct answer is option C.
