How is the age distribution pattern of the Hawaiian Islands - Emperor Seamount chain explained by the position of the Hawaiian hotspot? Explain using evidence and reasoning.
Answer:
Find the explanation below.
Explanation:
The Hawaiian Islands is a series of islands positioned in what looks like a chain, which increases in age as one moves northwest. The Hawaiian hotspot was formed as a result of the collision of the tectonic plates in the outer part of the earth which caused the rise of a volcano, and which in turn gave off magma which came to rest on a seafloor. That eruption on the seafloor is the hotspot.
This hotspot remains unmovable while the tectonic plates are in constant motion around the hotspot, giving rise to further Islands. This explains the age distribution pattern of the Hawaiian islands which arrived at different times making some older than the others.

Plants such as the Venus Flytrap and the Sun Dew attract and consume insects. These plants are unable to produce substances which break down the insect into compounds that are usable by the plant. The chemical compound that breaks down the insects is most likely * O ATP O Lipids O Enzymes O Vitamins
Answer:
The chemical compound that breaks down the insects is most likely enzymes.
Explanation:
Venus flytraps and sundews are carnivorous- they consume insects to absorb nutrients via digestion. During absorption, their cells take up molecules synthesized via the breakdown of macromolecules like carbohydrates and proteins. When regions of the plant come into contact with insects, these plants recognize specific macromolecules like chitin, they increase the production of digestive enzymes.
Forming digestive liquid enzymes are specialized proteins that function as biological catalysts to speed up reactions. They act on substrates, which can bind to specific regions of the enzyme, called the active site. Once bound in the presence of highly specific temperature and pH, enzymes increase the rate of a reaction over time.
Common enzymes found in their digestive secretions include chitinases, phosphatases, amylases, and proteinases.

Explain why your model demonstrates how crossing over is important to genetic variation in a species
Answer:
Crossing over is essential for the normal segregation of chromosomes during meiosis. Crossing over also accounts for genetic variation, because due to the swapping of genetic material during crossing over, the chromatids held together by the centromere are no longer identical.

What is the driving force for plate tectonics?
A.Gravity slab pull
B.The gravity of the Moon and Sun
C.Heat from the Earth's core causing mantle convection
Answer:
Option C
Explanation:
Driving force for plate tectonics is the "convection in the Earths mantle" or option C. Convection is the transfer of heat due to the movement in molecules also causing hot to rise and cold to sink. Convection currents cause the tectonic plates to move because the currents rise to the Earths surface forcing the plates to drive away from each other also known as seafloor spreading.

Luis created a clay model of Earth. He used a toothpick to represent Earth's axis. The toothpick was stuck horizontally through the center of the Earth model, slightly to the side of each pole. He then used a flashlight to shine light on part of the Earth. Finally, he used the toothpick to spin the model Earth. What do you think Luis is trying to model?
Earth's revolution
Earth's rotation
Earth's day and night
Earth's seasons
Answer: Earth's rotation
Explanation:
Luis was most trying to model the Earth's rotation. As you know the earth rotates around it's axis once every 24 hours and this is why we have different times in the day because the sun shines on different parts of the Earth as it rotates.
Luis used the flashlight as the sun and when he used the toothpick to spin the model of earth, the model would represent earth rotating around its axis.
Answer:I think it’s earths day and night
Explanation: it says that he is flashing a light to one side of earth so I think he’s trying to show the day and night cycle
A defensive soccer player is having trouble reacting quickly to the movements of the opposing player. How can the soccer player adjust her base of support to improve her reaction time?
Answer:
decrease the base of support and centralize her line of gravity
Explanation:
A wider base of support leads to an unsteady gait. The base of support is the contact between the feet of the soccer player and the surface (the field) supporting him. The root cause of the player's inability to react quickly to the movements of the opposing player is a lack of balance.
Balance is the ability of an individual to sustain the line of gravity which runs the center of gravity. For the player to regain his balance, she needs to decrease the base of support and centralize her line of gravity, so as to maintain balance.

Michael was watching the rain hit the sidewalk in front of his house. After a few minutes, he noticed a change in the precipitation and saw that the
precipitation had changed into ice pellets
The falling ice pellets later changed back to rain, and then the rain stopped and the sun came out. Relate each stage of the water to cycle to the way
it affects the weather.
Answer: Water cycle is a complex cycle of water in which the water is changed into various forms like solid, liquid, and gases.
Explanation:
In the higher atmosphere the water vapors condense to form clouds and they club to form the ice crystals. These ice crystals when strikes on the ground as precipitate or ice pellets again changes its form from solid to liquid rain. The precipitation can be in the form of rain or wet snow. The rain stops when the concentration of water vapors in the higher atmosphere reduces and sun may come out.
The water cycle is a complex cycle of water in which the water is changed into various forms like solid, liquid, and gases.
Define the water cycle?The water cycle illustrates the continuous action of water within the Earth and atmosphere. It is a complicated system that has many different processes.
Liquid water evaporates into water vapour, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
Thus, water is changed into various forms like solid, liquid, and gases.

Rotenone, a piscicide (fish poison), interferes with the transfer of electrons between Complex I and Complex II in the process shown above. Which of the following results would be expected in the mitochondria of fish exposed to Rotenone? Why?
Answer:
Mitochondria stops working.
Explanation:
When the mitochondria of fish exposed to Rotenone, it inhibits the cellular respiration which is the main cause of death of fishes. This inhibiting of cellular respiration in mitochondria leads to reduction in cellular uptake of oxygen and this reduction is responsible for the death of fishes. This Rotenone releases by the plants present in the water as well as used as pesticides for killing of fishes.

a. 8 grass/m2
b. 16 grass/m2
c. 24 grass/m2
d. 32 grass/m2
Answer:
16grass/m²
Explanation:
Given parameters:
Number of grasses in quadrat = 4
Area of the square = 0.25m²
Unknown:
Population density = ?
Solution:
Population density is the number of organisms per given area;
Population density = [tex]\frac{number of grasses}{area of quadrat}[/tex]
Population density = [tex]\frac{4}{0.25}[/tex] = 16grass/m²

Answer:
Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: esporulación.
Explanation:
En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.
