what is one way that rna differs from dna? it forms a double helix. it forms a double helix. it is not soluble in water. it is not soluble in water. it is single-stranded. it is single-stranded. it has no nucleus.
Correct answer is E. It is single-stranded.
What is the difference between DNA and RNA?
DNA and RNA vary primarily in that whereas RNA has single-stranded molecules, DNA contains double-stranded ones. Deoxyribonucleic acid, also known as DNA, and ribonucleic acid, also known as RNA. Genetic information is carried by both DNA and RNA, but there are several key distinctions between the two. Deoxyribose, a sugar, makes up DNA, while ribose, a sugar, makes up RNA. Deoxyribose has one less -OH group than ribose. Another distinction is that whereas RNA is not stable in an alkaline environment, DNA is.
All genetic information is encoded in DNA, which also serves as the building block for all biological life. And only in the near future. In the long run, DNA serves as a storage medium, a biological flash drive that enables the transmission of the genetic code from one generation to the next. RNA works as the reader that decodes this flash drive. There are distinct RNAs for each phase in this multi-step reading process. We examine the three most crucial RNA kinds in further detail below.

Extra neurotransmitters are absorbed into the presynaptic neuron through __________. a. pumps b. osmosis c. terminals d. reuptake please select the best answer from the choices provided a b c d
D. Reuptake helps to absorb neurotransmitters into presynaptic neuron.
Substances that neurons utilize in communicating with one another are called Neurotransmitters. When an action potential reaches the terminal, presynaptic neurons release neurotransmitters. The neurotransmitter diffuses across the synapse and attaches to post-synaptic cell receptors. Reuptake or the reabsorption of a neurotransmitter occurs when a neurotransmitter transporter found at the pre-synaptic neuron at a synapse or along the axon terminal plasma membrane or along a glial cell has completed its job of sending a neural impulse.
When a neurotransmitter is broken down by an enzyme into smaller inactive products, which are subsequently reabsorbed by the presynaptic neuron and resynthesized into active neurotransmitter, this might result in reuptake.

What are Autotrophs?
Autotrophs are living things that can make their own nourishment from inorganic resources. The roots of the terms "autotroph" are "self" and "troph," which refer to nourishment. An autotroph is an organism that can sustain itself entirely without the help of other living things.
Because they are necessary for the existence of all other life forms, autotrophs are very significant. For instance, there would be no herbivorous animals and no carnivorous creatures that consume herbivores if there were no plants that used carbon dioxide gas and sunshine to produce carbohydrates. Autotrophs are frequently referred to as "producers" because of this. They give the energy that all heterotrophs (organisms that must obtain their food from others) need in order to thrive, and they are the foundation of an ecosystem's energy pyramid.

Sandy Soils have large particles and have large air spaces. How does this affect
the way the soil holds water way the air
Since sandy soils have large air spaces and large particles it cannot hold water. Light, warm, and dry sand has a tendency to be acidic and deficient in nutrients. Due to their high sand content and low amount of clay, sandy soils are frequently referred to as "light soils" (clay weighs more than sand).
These soils are simple to work with and have quick water drainage. Compared to clay soils, they warm up more quickly in the spring, but they tend to dry up in the summer and have low nutrient levels that are washed away by rain.

The sickle-cell allele most likely originated when a mutation occurred in a normal hemoglobin allele. If the trait arose in africa, where did it most likely originate?.
Additionally from Africa came the Sickle-cell allele, which most likely developed when a mutation in a normal hemoglobin allele took place. The sickle-cell allele most likely developed close to Kinshasa (in Congo).
A recessive allele of the hemoglobin gene is responsible for the sickle cell anemia characteristic. This implies that in order to have the condition, you must have two copies of the recessive gene – one from each parent. One dominant and one recessive copies of the allele prevent the development of sickle cell anemia in individuals.
An genetic condition where the red blood cells do not persist as long as normal red blood cells, have an irregular crescent form, and obstruct tiny blood arteries.
It turns out that because the mutation gives some resistance to malaria in certain places, HbS carriers have been naturally chosen. When the malaria parasite infects them, their red blood cells, which include some aberrant hemoglobin, have a tendency to sickle.

State the form in which the energy is present in the carbohydrate eaten by the wildebeest
The energy present in the carbohydrate eaten by the wildebeest is stored in the form of chemical energy.
After digestion, carbohydrates are converted into glucose for quick energy uptake or immediate energy requirements. Carbohydrates are converted into glycogen or fat for long-term energy storage.Sugars serve as the building blocks for the polymers that make up carbohydrates.In humans and other vertebrates like wildebeest, glucose is stored in the form of glycogen, which is composed of glucose monomers. Glycogen, a very branched molecule that is often retained in muscle and liver cells, is the animal analogue of starch. Glycogen is broken down to release glucose whenever blood glucose levels drop.Therefore, energy of carbohydrates is stored as chemical energy in the form of glycogen in herbivorous mammals such as the wildebeest.

8. Name the process that the graph represents. Describe this process.
The graph represents negative feedback mechanism which includes most homeostatic control mechanisms.
In the human body, negative feedback mechanisms are important for maintaining health. A negative feedback loop, sometimes referred to as an inhibitory loop, enables the organism to control itself.
The process begins when a biological system produces more, which raises the levels of specific proteins or hormones in the body. This inhibits or reverses the system's ability to produce in the future. As a result, when proteins or hormone levels rise too high, the body decreases the amount of these substances it produces.

Flattie spider or wall crab spiders have a higher chance at catching its prey.
The quickest leg-driven twisting movement of any terrestrial animal is possessed by the family of spiders known as Selenopidae, which includes flattie spiders and wall crab spiders. Although the crawler's rapid revolutions appear blurry to the untrained eye, their speeds are equivalent to those of aerial spinners like hummingbirds and fruit flies.
We discovered that the leg closest to the prey anchors to the ground, providing the spider with a point of leverage from which it may draw its torso in closer to the prey.
Eight laterigrade, or sideways moving, legs are used by flattie spiders to cover their entire body in all directions. The spiders are able to spin in this ready-to-fire, outward position.
