Which is the most likely result if the Ubx gene was activated either before or after it normally is activated in the sequence of Hox gene expression?
A. The insect develops slightly shorter or longer abdominal legs.
B. The insect develops normal body parts at either a slower or more rapid rate.
C. The insect develops normal body parts but in an altered time sequence.
D. The insect develops legs in other parts of its body.
Answer:
D. The insect develops legs in other parts of its body.
Explanation:
HOX genes, also known as homeotic genes, are evolutionarily conserved genes (containing homeobox sequences) that encode master regulators of embryonic development in animals. Hox genes modulate the body plan of an embryo along the head-tail axis. In general, these genes are arranged in the same order as they are transcriptionally expressed along the anteroposterior body axis. Moreover, Ultrabithorax (Ubx) is a Hox gene that is responsible for the proper development of the third thoracic segment in insects. In Drosophila, it has been shown that different segments of the leg regulate their size in response to Ubx expression.

How is energy produced by respiration stored
Answer:
Explanation:
Cellular respiration converts the chemical energy stored in glucose into chemical energy stored in the ATP molecule. The cells break glucose down into carbon dioxide and water while producing energy that they store in ATP molecules.

The top left, would be light energy from the sun, while the top of the circle would be living beings. Think about it just like plants that that gain energy from the sun through photosynthesis. Then the bottom of the circle would be nonliving beings, either decomposed plants or animals that bring nutrients to soil, or dead ones that we eat. This cycles through until the energy is rereleased through heat. Therefore the top right would be heat energy, every living thing on earth creates gradual amounts of heat. Imagine going for a run, you'll probably be hotter afterwards right? I know it's not the most scientific answer but its 100% right.

Why do birds migrate south during the winter?
A. strong northern winds drive them south
O B. an increase in predators drives them south
O C. to find food
O D. to find better nest building materials
Answer:
C. to find food.
Explanation:
It is hard to find food in the winter for animals besides humans. So they need to head south for warmer climates.

A cellular biologist is curious as to why a protein is not being expressed even though they placed the needed transcription factors and ribosomes allowing for the transcription and translation of the protein to take place in the cell. They look at the mRNA and find it is being translated and exported to the nucleus but ribosomes are not binding to it. After careful observation she finds out that the mRNA is missing its _____________. Without this of course ribosomes would have an issue binding to the mRNA and inducing translation.
Answer:
5' cap
Explanation:
In eukaryotes, the 5′ end of mRNA in eukaryotes is modified (i.e., capped) with a guanine nucleotide which is connected to mRNA via 5´→ 5´ triphosphate linkage. The five-prime cap (5′ cap) is denoted as 7-methylguanylate cap (m7G) because guanosine is methylated at the 7 position by a 7-methyl transferase. This cap acts to protect the mRNA from degradation and also is required during translation initiation in order to mediate a process known as ribosome recruitment. This process (ribosome recruitment) occurs through the association of the 43S preinitiation complex (composed of the small ribosomal subunit, eIF1, eIF1A, eIF2, eIF3 and eIF5 factors) with the 5' capped mRNA. After mRNA binding, the 43S preinitiation complex is ready to scan an initiation codon in order to start the translation.
what triggers angry in the brain?
Answer:
amygdala
Explanation:
Answer:
Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression. Epinephrine or adrenalin released by medulla of the adrenal glands, surges at the time of panic and emergency. It provokes stress response and brings out the arousal of extreme emotions like fear, anger or amusement.

Earth's core is the source of the energy that drives the movement of tectonic plates. Which two processes help transfer this energy outward to earth's crust?
Answer:The two processes are CONDUCTION and CONVECTION
Explanation:
The Energy produced in the Earth core is generated by Sun, gravitational force , radioactive decay, and the Earth' rotation, To maintain balance in the earth, The processes of CONDUCTION and CONVECTION transfer energy (HEAT) to Earth's interior, which also helps the movement of tectonic plates at a constant rate.
Now, inside the earth mantle is made up of hot solid rock and because Conduction occurs more in solids, Its currents helps the continuous transfer of heat energy from the warmer mantle at the bottom to the cooler mantle at the top While Convection currents in the core move thermal energy causing the rising and sinking of warm and cooler molten rock inside Earth, thereby maintaining the motion of tectonic plates and creating a balance in the earth.
Answer:
Conduction and Convection

Complete burning of fossil fuels releases carbon primarily to what part of the biosphere?
NO LINKS OR I WILL REPORT YOU!
Answer:
Atmosphere
Explanation:
carbon dioxide is naturally released into the atmosphere by the decay and flatulance of animals. But you extract fossil fuels from the ground and burn them. The burning of fossil fuels is called combustion.

How does a fire help grasslands?
Choose all that apply
Answer:
In most grassland ecosystems, fire is the primary mode of decomposition
Explanation:
Grasslands burn more readily than forest and shrub ecosystems, with the fire moving through the stems and leaves of herbaceous plants and only lightly heating the underlying soil, even in cases of high intensity. In most grassland ecosystems, fire is the primary mode of decomposition, making it crucial in the recycling of nutrients. In some grassland systems, fire only became the primary mode of decomposition after the disappearance of large migratory herds of browsing or grazing megafauna driven by predator pressure. In the absence of functional communities of large migratory herds of herbivorous megafauna and attendant predators, overuse of fire to maintain grassland ecosystems may lead to excessive oxidation, loss of carbon, and desertification in susceptible climates. Some grassland ecosystems respond poorly to fire.
A fire helps grasslands through the following:
Keeps trees from overtaking the grasses.Preserve biodiversity.What is Fire?This is the visible aspect of combustion of fuel and other materials to produce heat and flame.
controlled burning increases biodiversity by increasing spatial and temporal variation and helps prevent trees from overtaking grasses.
