Explain the difference: a myelinated axon conducts impulses faster than non-myelinated axon of the same diameter
Answer:
A myelinated axon conducts impulses faster than a non-myelinated axon. ... Therefore, in myelinated neurones, the nerve impulse is said to jump from node - to - node, a impulse pathway known as Saltatory Conduction. This means that the action potential does not have to travel along the whole length of the myelinated axon

in pairs, and are important in forming the spindle apparatus and cleavage furrow during the division in animal
cells?
Answer:
some cell made from s****x. baby from
Centrioles are paired barrel-shaped organelles located in the cytoplasm of animal cells near the nuclear envelope. Centrioles play a role in organizing microtubules that serve as the cell's skeletal system. They help determine the locations of the nucleus and other organelles within the cell.
In the early days of life on Earth, plants were exposed to extremely high doses of ultraviolet radiation, Constant UV exposure
resulted in some land plants developing narrow leaves with thick, waxy cuticles. Over many, many generations, these narrow
leaves evolved into needles.
Relate the development of plant needles to the occurrence of mutations,
A)
Plant needles adaptations for survival that some plants developed due to
high temperatures on Earth
B)
Plant needles are the result of leaf cell mutations that made some leaves
thick and waxy, while other leaves did not change,
Plant needles are the result of neutral mutations to leaf tissue that would
neither help nor harm the plants living in such a harsh environment.
D)
Plant needles were a beneficial mutation that increased survival of certain
plants that reproduced and passed the mutated gene to offspring,

Explain how building the lake near Galetown could affect the amount of water vapor and the amount of rain.
Answer:
Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)

1. Stern cells are different from other cells, as they are not specialized and can reproduce other unspecialized cells. There has been great controversy over the use of stem cells in the United States, especially when they are taken from fetal tissue. What are some possible benefits to humans of using stem cells?
plz hellllp
Answer:
Stem cell benefits:
Can repair limbs such as Arms cut off etc.

Can reduce the effect on diseases
Test new drugs for safety and how effective they are
Make people live longer and healthier lives
Explanation:
Humans aren't aware on how to harvest stem cells effectively in a way they work on humans tot heir full potential but the reasons I listed above are only the tip of the iceberg when it comes to what we can do with these.

D. Errors During DNA Replication ✨
[tex]\color{Violet}\rm{☘︎Hopeithelps!}[/tex]
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.[tex]\color{gold}{✨•MissyyZackiee•✨} [/tex]__________________________________

En este dominio existen gran variedad de procariotas, con diversidad morfológica y fisiológicas, en este están todas
las procariotas patógenas, su tamaño oscila entre 1 y 40 milimicras, es
a) Protista
b) Eubacteria
c) Archaea
d) Eukaria
Answer:
c) Archaea
Explanation:
Los dominios biológicos son los taxones de más alto nivel, por encima de los reinos y abarcando todos los taxones, caracterizándolos de la manera más generalizada posible, dentro de la clasificación científica. Hay tres tipos de dominios llamados Archaea, Bacteria y Eukarya. Entre ellos, el dominio conocido como Archaea es el que engloba a los organismos procarióticos, unicelulares y patógenos, es decir, capaces de provocar enfermedades en el ser humano.

¿A que evidencia de la evolución hacen referencia los arboles evolutivos?
A.Embriologia
B.Registro fosil
C.Distribucion geografica
D.Grupos taxonomicos
E.Anatomia comparada
Answer:
B. Registro fósil
Explicación:
El registro fósil es la evidencia de la evolución a la que se refieren los árboles evolutivos. La relación entre organismos se puede averiguar estudiando fósiles de organismos. Los árboles evolutivos también se denominan árbol filogenético y muestran las relaciones evolutivas entre varias especies basadas en similitudes y diferencias en sus características físicas o genéticas. Se consideran similares aquellos organismos que tienen las mismas características físicas o genéticas.

As native mason bees visit flowers, they spread pollen while also consuming nectar from the plant. This is an example of symbiosis.
true or fasle
Answer:
True
Explanation:
Symbiosis is a type of relationship or interaction between two different biological organisms/species by which both are benefited. The bees such as mason bees are pollinators. Pollinators are animals (especially insects) that help the development of seeds and the fruit surrounding seeds by the pollination of flowers, i.e., by the transference of pollen from male anthers of a flower to the female stigma. During this process, pollinators eat nectar, which is a sweet energy-rich liquid secreted by flowers. In consequence, both species (i.e., plants and mason bees) are benefited from this interaction.
Modern classification systems are based on structural similarities, fossil record and
- modern classification is based on figuring out evolutionary relationships using evidence from living species, the fossil record, and molecular data. - the evolutionary history for a group of species. ... - each species in a clade has some traits that have changed from its ancestors over evolutionary time.

Our atmosphere acts like a blanket trapping heat and keeping Earth at a habitable temperature, it’s this retaining of heat that is referred to as the Greenhouse Effect. The greenhouse effect is caused by greenhouse gases that trap heat from the sun, the more greenhouse gases there are the more heat is retained
HOW IT WORKS
The heat from the sun (solar radiation) has a very short wavelength and this can pass easily through the layer of greenhouse gases. This wavelength is called Ultraviolet radiation. As the UV rays strike the Earth, the Earth redirects the rays back into the atmosphere. We feel this as heat. The heat from the earth (terrestrial radiation) has a longer wavelength (infrared) some of this becomes trapped by the layer of greenhouse gases.
GREENHOUSE GASES
Water vapor (H20) is the most prevalent greenhouse gas and occurs naturally. Some greenhouse gases are both natural and man-made including carbon dioxide (CO2) & methane (CH4).
Describe the size of insolation when it strikes the Earth.
What would happen if there were no greenhouse gases to trap heat?

what law out of newtons law is this statement ? please help
( The phone will hit the ground and the ground will push up with the same force. With a case, it is increasing the amount of time the phone hits the ground. This means the reaction force will be less.)
Answer:
Newton's Third Law
Explanation:
Newton's Third Law is: If object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
In this case, Object A is the Phone, and Object B is the ground. When the phone(Object A) hits the ground(Object B), the ground pushes up on the phone making the time increase and makes the reaction force less. Hope this helps!
