How does RNA polymerase know where to start and stop making a strand of RNA?
Answer:
Each gene has a beginning and an end. At the beginning of each gene is a similar sequence that tells the RNA polymerase to start working. The same is true at the end of each gene where a specific sequence tells the RNA polymerase to stop transcription

Which planet has a longer day than year?
OVenus
O Neptune
O Earth
Answer:
VENUS
Explanation:
On Venus, one rotation on its axis takes the equivalent of 243 Earth days and the planet's orbit around the Sun takes the equivalent of 225 Earth days.
Answer:
Venus, I think
Explanation:
So outta these three, Venus is the closest to the sun, so the year is the shortest. Venus is also the planet with the longest day averaging at 116d 18h, so I think that's the right one. Sorry if this is wrong

bacteria use this form of reproduction
Answer:
Bacteria reproduce by binary fission. In this process, the bacteria, which is a single cell, divides into two identical daughter cells.
Explanation:
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates).

A __________ is an example of a signal molecule that can bind to an intracellular receptor and thereby cause a gene to be turned on or off. a protein b glyceride c nucleic acid d steroid e carbohydrate
Answer:
D. steroid
Explanation:
Intracellular receptors are a type of receptors located inside the cell, specifically in the cytoplasm or nucleus. When intracellular receptors are activated by ligands called SIGNALLING MOLECULES, they change shape and regulate genetic expression in the nucleus i.e. they induce turning on and off in a gene.
However, signalling molecules that activate intracellular receptors are usually hydrophobic hormones because they need to easily diffuse through the cell membrane and bind to the receptors located internally. Example of these hydrophobic signal molecules are STEROIDS.

How are hydrogen bonds related to polarity?
Answer:
Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions

What is the greatest threat humans pose to biodiversity?
Answer:
habitat loss, over-harvesting, and introduction of exotic species
Explanation:
The way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.
What is biodiversity loss?The term "biodiversity loss" describes the decline in biodiversity brought on by the extinction or relocating of species. Some people might not consider the extinction of a certain species to be significant, especially if it is not a charismatic species such as the Bengal tiger or the humpback dolphin.
However, according to estimates from scientists, the present pace of species extinctions is several times higher than the background, or average, rate seen throughout Earth's history. Within our lifetimes, this amounts to the extinction of tens of thousands of species.
The breakdown of ecosystems is anticipated to have drastic repercussions on human welfare. Because of the intricate relationships between species, a loss of biodiversity may have a ripple effect on ecosystems.
One species' extinction, for instance, may result in the extermination of another. Scientists evaluate which species are in danger of extinction as well as the state of the ecosystems to gauge the loss of biodiversity.
Therefore, the way that people have altered natural environments to create room for farms or to collect natural resources has posed the greatest harm to biodiversity yet, but as climate change intensifies, it will have a rising influence on ecosystems.

Maja puts a hockey puck onto ice. After a while the temperature of the hockey puck decreases. What happens to the molecules of the hockey puck when the temperature of the puck decreases?
Answer: The energy of the molecules in the hockey puck decreases.
Explanation:
When the temperature of the hockey puck decreases, then the energy of the molecules in the hockey puck decreases as well.
In this scenario, when the temperature of the hockey puck decreases, then the hockey puck will gain heat molecules and the cold energy of the molecules that are in the hockey puck will reduce.
How do wales differ from fish
Answer:
Whales are mammals that need air from the sea's surface to survive. Whales are capable of giving birth to live young. Fish have gills and use them to draw oxygen from the water. The majority of fish lay eggs. Whales and other marine animals with horizontal tail fins, such as dolphins, have vertical tail fins, while fish have vertical tail fins.
