Which of the following statements is true? Which of the following statements is true? No archaea are capable of using CO2CO2 to oxidize H2H2, releasing methane. Prokaryotes have low levels of genetic diversity. Archaea and bacteria have identical membrane lipids. The cell walls of archaea lack peptidoglycan.
Answer:
The correct answer is - The cell walls of archaea lack peptidoglycan.
Explanation:
Archaea are the prokaryotes that are different from bacteria in various ways but the most important differences are the membrane lipids and the major component of the cell wall that lacks peptidoglycan found in the cell wall of bacteria.
These prokaryotes are able to use carbon dioxide to oxidize hydrogen, releasing methane. Archaea-like prokaryotes have a high level or complex genetic diversity.

Explanation:
magine that a scientist takes a group of Anolis lizards and introduces them into an enclosure at a research facility in continental South America. He notes that the lizards thrive in this new environment. The fact that Anolis lizards could survive in habitats outside of the Caribbean is a reflection of their ____ niche; their _____ niche is determined by their ability to disperse to other areas as well as predation and resource availability.
Answer: Fundamental, realized
Explanation:
The realized niche of a species is usually the result of predation, competition, and other types of interaction between species.
The size of realized niche is determined by interspecific competition .The fundamental niche is larger than the realized niche.
The fundamental niche represents all the habitats where a species could possibly live, but competition among different species usually restricts a species to a smaller area, which is the realized niche

results in the formation of ADP.
occurs in the chloroplast
Answer:
I don't know the answer to the first one, but I can answer the second question. Cellular respiration has carbon dioxide and water as waste products.
Explanation:
Cellular respiration does not form glucose & oxygen and doesn't occur in the chloroplast, but does form ATP energy, carbon dioxide, & water and the process occurs in mitochondria. Photosynthesis on the other hand forms glucose & oxygen and does occur in the chloroplast.

Imagine taking a bite of a pizza. Briefly discuss the role that each part of the brain takes in this simple act. Medulla, Pons, Cerebellum, Thalamus, Hypothalamus, Amygdala, Hippocampus, Parietal Lobe, Occipital Lobe, Temporal Lobe, Frontal Lobe.
Answer:
- Medulla: transmits signals between the spinal cord and higher brain levels
- Pons: transmits impulses related to the voluntary skeletal movements from the cerebrum to the cerebellum
- Cerebellum: coordinates skeletal muscle contraction, conscious/subconscious movements, maintains muscle posture, and balance
- Thalamus: regulation of the human nervous system
- Hypothalamus: maintains the overall homeostasis of the body
- Amygdala: processes fearful and threatening stimuli
- Hippocampus: regulates learning, memory encoding and consolidation, and spatial navigation
- Parietal Lobe: processes information from the outside world (e.g., touch, taste, temperature)
- Occipital Lobe: interprets information from the eyes
- Temporal Lobes: process sensory information (i.e., pain and auditory stimuli)
- Frontal Lobe: higher cognitive functions (e.g., memory, problem-solving, emotions, impulse control, etc)
Explanation:
The medulla (medulla oblongata) is the lowest portion of the brainstem, which is linked by the pons to the midbrain and continues with the spinal cord. The medulla is known to transmit signals between the spinal cord and higher brain levels, thereby controlling autonomic activities (e.g., heartbeat and respiration). The pons is a mass of transverse nerve fibers that links the medulla with the cerebellum, it transmits signals from the forebrain to the cerebellum. The pons is involved in different functions, e.g., sleep, respiration, hearing, equilibrium, taste, eye movement, swallowing, bladder regulation, facial expression, etc. The cerebellum is a small part of the brain involved in physical movements (e.g., posture, balance, coordination), which receives sensory information from sensory systems, the spinal cord, and different parts of the brain. The cerebrum is the largest part of the brain, it is involved in speech, thinking, reasoning, problem-solving, emotions, initiating/coordinating movements, regulating temperature, learning, etc. The thalamus is a mass of gray matter located in the forebrain which is involved in diverse functions (i.e., relay of sensory signals, regulation of consciousness, sleep, alertness, etc). The hypothalamus is a small, central, area of the brain that connects the nervous to the endocrine system that acts to maintain the overall homeostasis of the body. The amygdala is a structure located in each hemisphere of the brain that processes fearful and threatening stimuli. The hippocampus is a structure located in the depths of the temporal lobe that regulates learning, memory encoding and consolidation, and spatial navigation. The parietal lobe is located at the upper back area in the skull, it is involved in processing sensory information from the surrounding world (e.g., touch, taste, temperature). The occipital lobes are responsible for transmitting visual information to the temporal lobes, and they are also associated with memory skills. The frontal lobe is the most anterior part of the brain, which is involved in higher cognitive functions (e.g., social interaction, motor function, memory, emotions, impulse control, problem-solving, etc).

What renal and hormonal factors will cause an increased release of aldosterone from adrenal cortex?
Answer:
Renin; angiotensin I and angiotensin II
Explanation:
Renin is a key hormone involved in the renin-angiotensin-aldosterone system (RAAS), which is responsible for regulating blood pressure in response to changes in blood volume. Renin is secreted primarily by the kidneys to promote the production of the peptide hormone angiotensin in the blood vessels. Subsequently, angiotensin stimulates the release of aldosterone from the adrenal cortex, stimulating sodium retention by the kidneys. Renin acts on its substrate angiotensinogen to yield angiotensin I, which is then converted to angiotensin II by the angiotensin-converting enzyme (ACE). Finally, angiotensin 2 promotes the release of aldosterone by the adrenal cortex, which acts on renal tubules, leading to the reabsorption of sodium and water and the excretion of potassium.

1.- Embrión se desarrolla dentro del sistema reproductor femenino.
2.- Formación de un organismo a partir de huevos
Answer:
1. Vivíparo
2. Ooviparismo
Explanation:
Viviparismo se define como el proceso de desarrollo de un animal en el cual el embrión crece dentro dentro del sistema reproductor femenino en una estructura acorde que le permite obtener alimento y oxígeno hasta su nacimiento. El viviparismo placentario es el tipo de desarrollo más extendido entre mamíferos (por ejemplo, perros, caballos, gatos, conejos, etc), a excepción de mamíferos que son ovíparos (por ejemplo, el ornitorrinco) y los mamíferos marsupiales que no poseen placenta y donde feto se desarrolla en una bolsa externa llamada marsupio (por ejemplo, los canguros). Por otra parte, el oviparismo es un mecanismo de desarrollo en el cual el embrión crece dentro de un huevo desde el momento que la hembra lo expulsa hacia el exterior. Cuando se produce este suceso, los embriones se encuentran muy poco desarrollados y por lo tanto deben cumplir su ciclo de crecimiento (hasta eclosionar del huevo) fuera del vientre materno. Algunos ejemplos de animales ovíparos incluyen anfibios, reptiles, aves, insectos, etc.
