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.
¿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.

There are 42 gallons in one barrel of oil. How many barrels of oil are equivalent to 2,572.5 gallons of oil?
Answer:
The 62.25 barrels of oil are equivalent to 2562.5 gallons of oil
Explanation:
Given that :-
There are 42 gallons in one barrel of oil.
To find :-
How many barrels of oil are equivalent to 2,572.5 gallons of oil?
Solution :-
If 42 gallons oils in one barrel of oil
so, barrels of oil are equivalent to 2562.5 gallons of oil = 257.5/ no. of gallons in one barrel
= 257.5 / 42
barrels of oil equivalent to 2562.5 gallons of oil = 61.25Hence, 62.25 barrels of oil are equivalent to 2562.5 gallons of oil

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,

in the gizmo what conditions is the light intensity a limiting factor
The limiting factor was CO2 because when it was decreased or increased, it was still able to increase the oxygen production. I know that CO2 is the limiting factor because it always increases oxygen production.. Challenge: In each of the situations below, use the Gizmo to find the limiting factor.

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.
Describe how organ systems interact to get oxygen to the cells
The body's cells are supplied with oxygen and nutrients through the heart, blood, and blood vessels. Blood transports carbon dioxide to the lungs (for exhale) and picks up oxygen through the network of arteries, veins, and capillaries.
What is oxygen in the body?Our bodies require a specific amount of oxygen to function effectively since oxygen is necessary for life. When you breathe (inhale), oxygen enters your body through your mouth or nose and travels through your lungs into your bloodstream.
Oxygen inhaled by the lungs is also carried by your blood. Your body's other cells receive oxygen and nutrition from your circulatory system, which then collects any waste products they produce, including carbon dioxide, and transports them to your kidneys and lungs for elimination.
Therefore, the blood collects food nutrients from the small intestine and transports them to every cell in the body.

5. Our nervous system and our skeletomuscular system help us react to stimuli. Give one example on how this helps us maintain homeostasis.
Answer
The nervous and skeletomuscular systems help maintain homostasis by regulating respiration.
Explanation:
The brain stem, consisting of the pons and medulla, represent the main respiratory center. According to Wikipedia, "an increased level of carbon dioxide in the blood, or a decreased level of oxygen, will result in a deeper breathing pattern and increased respiratory rate to bring the blood gases back to equilibrium."
This is an example of a homostastic response controlled by both of the organ systems referenced above.

Which statement best describes a characteristic of an ecosystem
Answer:
Infrastructure
Infrastructure is an important characteristic as it influences accessibility to the environment by land managers, and tourists alike. Unfortunately it can also increase the invasive potential introduced species, such as weeds and feral animals as road vehicles are well known to act as vectors for invasion of both weeds and feral animals. On the other hand roads improve access to implement various management programs, and also provide access for land users.

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!

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.)
