Natalie accelerates her skateboard along a straight path from 0 m/s to +4.0 m/s in 2.5 s. Find her average
acceleration.
Answer:
[tex]a=1.6\ m/s^2[/tex]
Explanation:
Given that,
Initial speed, u = 0 m/s
Final speed, v = 4 m/s
Time, t = 2.5 s
We need to find the average acceleration of Natalie. We know that average acceleration is equal to the change in speed per unit time. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{4-0}{2.5}\\\\a=1.6\ m/s^2[/tex]
So, her average acceleration is [tex]1.6\ m/s^2[/tex].

what is the advantage and disadvantage of the Ocotillo and Hummingbird relationship
Advantages:
The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.
The relationship between Ocotillo and Hummingbird is an example of a mutualistic relationship, which means that both species benefit from each other's presence.
What are the various advantages and disadvantages of the relationship ?The advantages and disadvantages of this relationship can be described as follows:
Advantages:
Ocotillo provides a source of nectar for hummingbirds, which is an important source of energy for their high metabolic rate.
Hummingbirds are efficient pollinators of Ocotillo flowers, which helps to ensure their reproduction and genetic diversity.
Ocotillo provides a nesting site for hummingbirds, where they can raise their young in safety from predators.
Disadvantages:
The relationship between Ocotillo and hummingbirds is specific and may not be beneficial to other species of plants or animals.
Ocotillo is adapted to living in arid environments and may not provide a suitable habitat for some other species of birds or animals.
If the population of either Ocotillo or hummingbirds were to decline significantly, it could affect the survival of the other species in the mutualistic relationship.
Overall, the advantages of the Ocotillo-Hummingbird relationship outweigh the disadvantages, and this mutualistic relationship is an important part of the ecosystem in which they both live.

Explanation:
3) Barry, a 62 year old man, suddenly fainted while walking inside Wal-Mart. He was
transported to the hospital. After several tests, they found that he broke his hip and needed
surgery. They also found that the oxygen level in his blood was very low and were concerned
that he was not getting enough oxygen to his brain, which must have triggered his fainting spell.
What systems are affected?
Why?
Answer:
three systems affected are:
1. respiratory system
2. skeletal system
3. nervous system
Explanation:
From the text, three systems are affected, and they are:
1. respiratory system
2. skeletal system
3. nervous system
1. Respiratory system. The statement "the oxygen level in his blood was very low" highlights that the body cells were not getting enough oxygen during respiration. This could either be during the gaseous exchange in the lungs or during cellular respiration.
2. Skeletal system: When Barry fell, he broke his hip. The hip bone is the bone that forms part of the pelvic girdle in the skeletal system.
3. Nervous system: It was also suggested that the fainting episode was because the brain was not getting enough oxygen for respiration and metabolism, hence the brain (central nervous system) was affected

Which processes directly connect the ocean to the water cycle?
A) Condensation and runoff
B) Precipitation and melting
C) Evaporation and condensation
D) Evaporation and precipitation
Answer:
D
Explanation:
I took the test for flvs, it was correct.
The process that directly connect the ocean to the water cycle is evaporation and precipitation. The correct option is D.
What is water cycle?The water cycle is a biogeochemical cycle that describes the continuous movement of water on, above, and below the Earth's surface. It is also known as the hydrologic cycle or the hydrological cycle.
The water cycle depicts the continuous movement of water within the Earth's and atmosphere's atmosphere.
It is a complicated system with numerous processes. Liquid water evaporates into water vapour, condenses into clouds, and falls back to earth as rain and snow.
The water cycle describes the exchange (cycling) of water through Earth's land, ocean, and atmosphere. Evaporation and precipitation are the processes that directly connect the ocean to the water cycle.
Thus, the correct option is D.

If a 15 amp circuit has a 9V battery in it, how much power is being generated?
Answer:
P = 135 Watts
Explanation:
Given that,
Current in the circuit, I = 15 A
Voltage, V = 9V
We need to find the amount of power generated. The formula to find the electric power is given by :
P = VI
Substituting all the values,
[tex]P=9\times 15\\\\=135\ W[/tex]
So, the required power is 135 watts.

Which pair of statements correctly describes a way that the chromatin contributes to gene expression?
Answer:
Chromatin is responsible for gene expression.
Explanation:
Chromatin is responsible for gene expression because chromatin contains DNA that has all information about genes. chromatin controls the gene in order to form encoded products. DNA in chromatin send information to the RNA to produce specific types of proteins that are needed by the organisms for its growth and development so in that way the genes can be expressed in the organism.

Which of the following is a abiotic factor that could limit the growth of the plant population?
Grasshopper population
Sunlight
Fish population
Bacteria in the water
Answer:
Sunlight
Explanation:
Plants are autotrophs which makes their own food in the presence of sunlight and the process is called photosynthesis. Sunlight is very important for the process of photosynthesis.
So, the only abiotic factor from the options that could limit the growth of the plant population is sunlight. plants can not make their food without sunlight and no food means no growth of plant population.
Hence, the correct answer is "Sunlight".

Compare the stroma and thylakoid in relation to their location in the chloroplast.
Answer:
The stroma is the watery part found in the inner membrane, which contains circular DNA molecules, RNA, ribosomes, lipids, granules of starch, among other substances. The chloroplast genetic process and photosynthesis reactions take place in the stroma. Thylakoids are flattened sacs, or vesicles, that form part of the inner membrane structure of the chloroplast to initiate the light-dependent photosynthesis reaction.
Explanation:
Chloroplasts are typical and exclusive organelles of plant cells that possess chlorophyll. It also has a double membrane (external and internal) and between them an intermembrane space. The inside is filled with a gel called a stroma. The stroma surrounds the thylakoid and grana within the chloroplast. It presents a DNA independent of the nucleus and plastoribosomes. Immersed in the stroma, there are flattened sacs called thylakoids or lamellae, the interior of which is called lumen. Thylakoids can spread throughout the stroma or stack in bundles called grana. Enzyme systems are located in the membrane of grana or thylakoids that capture energy from the sun and carry out the transport of electrons to form ATP.

The intense performance of CO2 (carbon dioxide) volcanoes allowed the Earth's heat to fix itself permanently in our atmosphere.
Explanation:
If an organism has high biological fitness in one environment, does that mean that it would also have high biological fitness in another environment? Why or why not?
Answer:
The answer is no, high biological fitness in one environment doesn't have to be high in another environment. Biological fitness is a term used in evolutionary biology and it is the quantitative representation of how a genotype (or phenotype) is successful (reproductively) in a certain environment. The biological fitness of an organism is dependent on its ability to survive and reproduce in a given environment. If different traits or alleles increase the fitness of an organism, those alleles will consequently increase in the gene pool, and that trait will increase in the population.
