Ovulation occurs in the ovary, forming the corpus luteum at the end of this phase. ovulation results in the release of an ovum from the ovary. the remaining follicle becomes a corpus luteum at the end of which uterine phase?
The luteal phase is one of the phases of ovarian cycle (follicular phase and ovulation are the other two). It is the final phase of the ovarian cycle and it corresponds to the secretory phase of the uterine cycle. During this phase, the transformation of the dominant follicle into the corpus luteum is stimulated by pituitary hormones FSH and LH. Corpus luteum produces progesterone which makes the endometrium receptive to implantation of the blastocyst.

What organ system is monetly responsible for generating behavior in multicellular animals?
Nervous system is the organ system that is mostly responsible for generating behavior in multicellular animals. The nervous system coordinates multicellular animal’s behavior and transmits signals within the body. Specific excitatory and inhibitory substances are produced by the nerve cells for them to interact with each other and certain chemicals, sound and light is detected by the sense organs such as ear and nose which control the behavior and movement of multi cellular animals in their environment.

Answer:
D. multicellular, eukaryotic, photosynthetic
Explanation:
I took the test and got it right
The characteristics that all plants have in common are they are multicellular, eukaryotic, and photosynthetic. Therefore, the correct option is D.
What are eukaryotic organisms?Eukaryotic organisms are the organisms which are multicellular and have a well-defined nucleus and other organelles.
Plants are multicellular organisms and are eukaryotic with well-defined membrane bound organisms. They are photosynthetic in nature, which means that they carry out the process of photosynthesis, which is the conversion of solar light to chemical energy for the production of glucose.
They are present under the kingdom Plantae which have cell wall made up of cellulose. They also have chloroplasts, which are centers of photosynthesis. They have specialized reproductive organs to carry out reproduction. Therefore, the correct option is D.

Final answer:
Making factories recycle water is the best choice among the given options to help conserve Earth's water supply. Other key strategies include using efficient irrigation systems like drip irrigation, planting native vegetation, installing water-saving devices, and reusing greywater for non-potable purposes.
Explanation:
The best way to help Earth’s water supply last for future generations is to implement practices that promote water conservation and efficient use. Among the options given, making factories recycle water is the best choice, as it can significantly reduce the industrial demand for freshwater by reusing processed water. Additional strategies include efficient irrigation techniques like drip systems emphasized in agriculture to minimize losses due to evaporation, and growing crops in areas where natural rainfall is sufficient thereby reducing dependency on irrigation. The use of native, drought-tolerant vegetation and water-saving devices such as low-flow toilets and faucets can further contribute to conserving water. Rainwater harvesting and the reuse of greywater for non-potable applications can also play an important role. It's crucial that we focus on these water conservation methods as agriculture is the largest user of water, mostly for irrigation, and enhancements in irrigation efficiency are particularly valuable for achieving sustainability in water resources.
Which of the following statements best proves that the law of conservation of mass is obeyed during photosynthesis?
A: The starting total number of oxygen atoms in carbon dioxide is equal to the ending total number of oxygen atoms in glucose.
B: The starting total number of oxygen atoms in carbon dioxide gas is equal to the ending total number of oxygen atoms in glucose and oxygen.
C: The total mass of glucose and oxygen formed from photosynthesis is equal to the total mass of carbon dioxide and water used up during the reaction.
D: The total mass of glucose and carbon dioxide formed from photosynthesis is equal to the total mass of oxygen and water used up during the reaction.
The answer is: C. The total mass of glucose and oxygen formed from photosynthesis is equal to the total mass of carbon dioxide and water used up during the reaction.
The law of conservation of mass states that in a closed system, the total mass of the reactants must be equal to the total mass of the products formed during a chemical reaction. This principle applies to the process of photosynthesis, which involves the conversion of carbon dioxide and water into glucose and oxygen.During photosynthesis, carbon dioxide and water molecules are the reactants, and glucose and oxygen molecules are the products. According to the law of conservation of mass, the total mass of the products (glucose and oxygen) formed must be equal to the total mass of the reactants (carbon dioxide and water) consumed.Option C correctly states this principle, indicating that the total mass of glucose and oxygen formed from photosynthesis is equal to the total mass of carbon dioxide and water used up during the reaction. This statement directly reflects the law of conservation of mass, ensuring that the total mass remains constant before and after the photosynthetic process.The other options either do not consider the masses of all reactants and products or incorrectly pair the masses of different substances, violating the law of conservation of mass.

The soft palate separates the oral cavity from the nasal cavity when raised and in contact with the pharyngeal wall.
During specific functions like swallowing and speech, the separation between the oral and nasal cavities is crucial.
Soft Palate Role: The soft palate (velum) serves as the primary separator.Elevation Action: When raised, it contacts the posterior pharyngeal wall.Closure Mechanism: Forms a seal to prevent airflow into the nasal cavity.Speech Articulation: Essential for articulating sounds clearly.Swallowing Function: Prevents food or liquids from entering the nasal passage.Coordination with Tongue: Works in coordination with the tongue and lips.Clinical Implications: Dysfunction can lead to speech disorders or nasal regurgitation.The fundamental excitable cell in the nervous system is the _____. see concept 49.1 (page 1084)
Neuron
Neuron can be defined as excitable cell that usually carries, processes and transmit impulses or electrical signals. Thus, they are known to be basic unit of the nervous system which includes the spinal cord and brain. However, the signals between s neurons occur via certain connections called synapses.
The fundamental excitable cell in the nervous system is the neuron. Neurons transmit electrical signals, called action potentials, to convey information and produce movements in response to stimuli. They are also involved in thought processes within the brain.
Explanation:The fundamental excitable cell in the nervous system is the neuron. Neurons are responsible for transmitting electrical signals, called action potentials, that convey information and produce movements in response to stimuli. They also play a crucial role in thought processes within the brain.
Neurons, the fundamental units of the nervous system, feature a cell body (soma), dendrites for receiving signals, and an axon for transmitting signals to other neurons or cells. Axon terminals release neurotransmitters, facilitating communication at synapses. Neurons exhibit electrochemical signaling, enabling the transmission of information throughout the nervous system, vital for cognition and behavior.

1. Protons and neutrons are present in the nucleus of an atom.
2. Boron has a smaller radius and the protons in carbon exert a greater pull.
The nucleus of an atom contains protons, which have a positive charge, and neutrons, which have no charge. Electrons, which have a negative charge, orbit around the nucleus in electron shells.
Boron is located to the left of carbon in the same row of the periodic table. As you move across a row from left to right, the atomic radius generally decreases. Therefore, boron has a smaller radius than carbon.
The protons in carbon exert a greater pull because the effective nuclear charge is higher due to the increased number of protons.
