Justine is ice-skating at the Lloyd center what is her final velocity if she accelerates at a rate of 2.0m/s for 3.5 seconds?
7 m/s
Explanation:
Acceleration,
Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.
Making v the subject then
v=at+u
Taking u as zero then
Substituting 3.5 for t, 2 as a then
v=3.5*2=7 m/s

Q: What is the purpose of Mitosis? Why do cells need to divide?

Answer:
The goal of mitosis is to divide a cell to produce two cells, each of which is identical to the parent cell. The cell cycle is the process by which cells multiply, which is necessary for an organism to survive.

Complete the passage about the process of subduction.
The subduction of
boundary often forms volcanoes. This phenomenon occurs because the underground pressure squeezes water out of the dense crust, and this water works its way into the mantle. The water
the mantle and allows for the creation of magma.
The collision between an oceanic and a continental plate, or two oceanic plates originate volcanoes. a) oceanic crust at convergent boundary b) heats up.
What are convergent boundaries?Collision area between two plates. Two continental plates might collide, or two oceanic plates, or one oceanic plate with a continental one.
In the last two cases, the thicker and older plate subduces under the other plate, and magma rises to the surface by crevices. The Himalayas and Los Andes are examples of these collisions.
Plates' movement might produce earthquakes. Also, collisions create volcanic arches and continental arches.
When one of the plates sinks under the other one, it reaches a depth where it melts and magma rises. Volcanoes get formed on the superior plate since magma flows over it.
The subduction of oceanic crust at convergent boundary often forms volcanoes. This phenomenon occurs because the underground pressure squeezes water out of the dense crust, and this water works its way into the mantle. The water heats up the mantle and allows for the creation of magma.

highest level of
classification. Today, the highest level of classification is the domain. Two of
the domains, Bacteria and Archaea both contain microscopic prokaryotic
organisms. What would be the best reason for scientists to separate the
prokaryotes?
A)There were too many species of prokaryotes to only have 1 domain for them.
B)It was determined that neither have chloroplasts.
C)Both organisms do not contain organelles.
D)Research showed differences in living environments.
Answer:
d
Explanation:whater
Research showed differences in living environments is the best reason for scientists to separate the prokaryotes. Therefore, option (D) is correct.
What are prokaryotes?The organisms known as prokaryotes lack a nucleus and other organelles in their cells. There are two distinct groups of prokaryotes: the archaea and bacteria, both of which are thought to have evolved along distinct evolutionary lines.
Prokaryotic organisms or prokaryotes are organisms that lack a true nucleus and membrane-bound cell organelles. Mycoplasma, cyanobacteria, and bacteria are all examples of prokaryotes.
A prokaryotic cell carries out every one of the fundamental roles that an ordinary cell performs. Reproduction, respiration, digestion, and other biological processes are among their capabilities.

Explanation:
a _____ force is when two forces cancel each other out and do not affect the motion of an object
Answer:
Friction and gravity are at work in each picture. Explain how each are at work and how they work together. Balanced forces - Two or more opposite forces are balanced forces if their effects cancel each other and do not cause a change in an object's motion.
Explanation:
Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

La principal función del aparato respiratorio es inhalar oxígeno y eliminar dióxido de carbono. El oxígeno inhalado penetra en los pulmones y alcanza los alvéolos. Las capas de células que revisten los alvéolos y los capilares circundantes se disponen ocupando el espesor de una sola célula y están en contacto estrecho unas con otras. Esta barrera entre el aire y la sangre tiene un grosor aproximado de una micra (1/10 000 cm). El oxígeno atraviesa rápidamente esta barrera aire–sangre y llega hasta la sangre que circula por los capilares. Igualmente, el dióxido de carbono pasa de la sangre al interior de los alvéolos, desde donde es exhalado al exterior.
La sangre oxigenada circula desde los pulmones por las venas pulmonares y, al llegar al lado izquierdo del corazón, es bombeada hacia el resto del organismo (véase Función del corazón). La sangre con déficit de oxígeno y cargada de dióxido de carbono vuelve al lado derecho del corazón a través de dos grandes venas: la vena cava inferior y la vena cava superior. A continuación, la sangre es impulsada a través de la arteria pulmonar hacia los pulmones, donde recoge el oxígeno y libera el dióxido de carbono.
Intercambio de gases entre las alveolas y los capilares
Para mantener la absorción de oxígeno y la emisión de dióxido de carbono, entran y salen de los pulmones entre 5 y 8 L de aire por minuto, y cada minuto se transfiere alrededor del 30% de cada litro (cerca de tres décimos de galón) de oxígeno desde los alvéolos hasta la sangre, aun cuando la persona esté en reposo. Al mismo tiempo, un volumen similar de dióxido de carbono pasa de la sangre a los alvéolos y es exhalado. Durante el ejercicio, es posible respirar más de 100 L de aire por minuto y extraer de este aire 3 L de oxígeno por minuto. La velocidad de entrada del oxígeno en el organismo es una medida importante de la cantidad total de energía consumida por este. La inspiración y la espiración se llevan a cabo gracias a los músculos respiratorios.

Which theory directly
contradicts the concept of
absolute zero?
A. Gravitational Theory
B. Kinetic Theory
C. Matter Theory
A sample of matter experiences a decrease in average kinetic energy as it continues to cool. One would anticipate that the particles will eventually come to a complete stop. The temperature at which particles should theoretically stop moving is absolute zero. Thus, option B is correct.
What theory directly contradicts concept of absolute zero?All molecules are predicted to have zero kinetic energy and, as a result, no molecular motion at absolute zero (273.15°C). Zero is a hypothetical value (it has never been reached).
Absolute zero signifies that there is no kinetic energy involved in random motion. A substance's atoms don't move relative to one another.
Therefore, Kinetic energy because it can create heat which goes against the absolute zero. A gas molecule's kinetic energy tends to zero when the temperature reaches absolute zero.

Marine iguanas feed on seaweed. Seaweed contains starch Starch is digested by enzymes in the digestive system. Explain why the shape of an enzyme is important for digestion.
Answer: The enzyme is a catalyst that speed up the rate of the reaction.
Explanation:
The enzyme can be defined as the protein that is involved in the catalytic activity of the reaction. The shape of the enzyme is important as it determines to which substrate it binds to. The enzyme is specific to the substrate and binds to a specific kind of substrate. During the digestion process the enzyme binds to the specific substrate like protein, carbohydrates, fats, and other biomolecules present in the food to simplify the digestion process. Starch is digested into maltose by the enzyme salivary amylase in the mouth.

Answer:
Explanation:
The Flowchart is in the picture below. I hope it would be helpful for you.
A nucleotide is a compound containing three component units namely a pentose sugar, a heterocyclic nitrogenous base and a phosphate group. The nitrogenous base present may be either purines or pyrimidine.
What is sickle cell anemia?The sickle cell anemia is one of a group of inherited disorders known as the sickle cell disease. It affects the shape of the red blood cells which carry oxygen to all parts of the body. In sickle cell anemia some red blood cells are sickle shaped.
Red blood cells are usually round and flexible, so that they move easily through blood vessels. The sickle shaped red blood cells are also called crescent moons. These sickle cells also become rigid and sticky which slow or block the blood flow.
SCD causes a basal substitution of adenine A to thymine T in the sixth codon of beta globin. This leads to the replacement of glutamic acid with valine in polypeptide chains of haemoglobin.
