What is the process in genetic expression?
Answer:
Explanation:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. It acts as both an on/off switch to control when proteins are made and also a volume control that increases or decreases the amount of proteins made.
Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.
Answer:
The answer is all of the above are correct.
Explanation:
Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:
CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.
Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

9. UGU-UUC-CCU-UAA
UGU-UCC-CUU-AA
Answer:
7. Substitution mutation
8. Substitution mutation
9. Frameshift mutation
Explanation:
A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.
A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.
In the following sequences, mutation has occured as follows:
7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.
8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.
9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

How do I make a Punnet Square without knowing if traits are Dominant or Recessive? I cannot refer to the parents of the current generation, so I have to rely on that generation to create a theoretical next generation.
If you are referring to a previous generation, that would probably mean that the traits they have are the dominant ones
Explanation:
if you know all the traits possible, then the ones the parents have of a previous generation are most likely the dominant ones, from there, you can hopefully figure out another generation. could you attach a picture if this didn't help? thanks
If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?
Answer:
U A A G C U G A G C
Explanation:
The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).
But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).
Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:
A T T C G A C T C G
Translate:
U A A G C U G A G C
So, the complementary mRNA sequence will be U A A G C U G A G C

Ethan began making a model to show the processes which resulted in the formation of oceans
Which of the following would be the next step in the process?
Crust is broken down
Earths crust moves
Earths plates meet
Sea floor spreading
The next step in the process is sea floor spreading. The correct option is D.
What is sea floor spreading?Tectonic plates, which are huge chunks of the lithosphere of the Earth, split apart from one another during the geologic process of seafloor spreading.
The oceanic basin is the result of sea floor spreading.
The ocean crust and its basins are formed when the sea floor spreads and separates after the basin has been filled with water.
All of these result from various plate interactions within the planet.
New ocean floors are created by volcanic activity at spreading centers at divergent borders after the crust has developed and accumulated water.
The production of fresh crust occurs close to the margin, and subsequent crusts push against and away from it. Ocean basins are created by the development of new ocean floors.
Thus, the correct option is D.

Hope it helps!!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).

¿Como se llama ?
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.
