Answer:
1) 945000 m
2) 6.11 miles/hour
3) 3.52 seconds
Explanation:
1. Speed is the time rate of change of distance, it is the ratio of distance to time. Speed is given by the equation:
[tex]speed(S)=\frac{distance(d)}{time(t)}[/tex]
Given that:
Time (t) = 9 hours and Speed (S) = 105 km/h
[tex]S=\frac{d}{t}\\ d=S*t=105*9=945km=945000m[/tex]
2) Time (t) = 0.9 hours and distance (d) = 5.5 miles
[tex]S=\frac{d}{t}\\ S=\frac{5.5}{0.9} =6.11miles/hour[/tex]
3) Acceleration it is the ratio of velocity to time. Acceleration is given by the equation:
[tex]Accceleration(a)=\frac{Final,velocity(u)-initial, velocity(v)}{time(t)}[/tex]
Given that :
a = 4.2 m/s² , u = 18.9 m/s and v = 33.7 m/s
[tex]a=\frac{v-u}{t}\\ t=\frac{v-u}{a}\\ t=\frac{33.7-18.9}{4.2}=3.52s[/tex]
Answer:
1) 945.000 meters
2) 9,84 kilometers/hour
3) 3,52 seconds
Explanation:
1) 105 km/h x 9 h = 945km
1km = 1000 meters 945 km = 945.000 meters
2) 1 mile = 1.61 km
5.5 miles x 1.61 km / 1 mile = 8,855 km
You have to do a single third rule to clear the x which is the Ann's velocity in 1 hour.
8,855km in 0.9 hs
x (velocity in 1 hour) = 9,84 km = 1 hs
1 hs x 8,855km / 0,9hs = 9,84km/h
v= 9,84km/h
3) you have to use this formula and clear T (time)
vf = v0 + a.t
vf-v0 = a.t
(vf - v0)/a = t
(33.7 m/s - 18.9 m/s) / 4.2 m/s2 = 3,52 seconds
What is the relationship between natural selection and adaptations?
Question 1 options:
Adaptations and natural selection are separate processes and not related
Natural selection occurs as a result of adaptations within a population
Natural selection is the process leading up to adaptations in a population
Natural selection and adaptations are actually the same thing
Answer:
The answer is C
Explanation:
Adaptations are the changes that occur from natural selection
Natural selection is the process leading up to adaptations in a population
What are adaptations?Evolutionary adaptation, is the process through which organisms adapt to their surroundings in order to improve their chances of survival.
what is natural selection?Natural selection is the adaptation and modification of populations of living organisms. Individuals in a population are naturally varied, which means they differ in certain aspects. Because of this variety, some individuals have characteristics that are better suited to their surroundings than others. Those creatures that are better adapted to their environment tend to live and reproduce more than those not.Natural selection is the process responsible for the emergence of adaptive characteristics and is one of the key mechanisms of evolutionary change.the best example to explain this is of Darwin's Finches. Many finches died because their beaks were too tiny to crack the thick seeds due to natural selection. The birds who were able to adapt bred and thrived, while the others died out as a result of natural selection.hence the correct option here will be that Natural selection is the process leading up to adaptations in a population

Which water source becomes polluted as it travels over the earth?
ponds
groundwater
oceans
O runoff
Runoff is the water source that becomes polluted as it travels over the earth. Therefore, option (D) is correct.
What is a runoff?Runoff refers to the water that flows over the surface of the earth, such as rainwater, snowmelt, or irrigation water. As runoff flows over the land, it can pick up pollutants such as chemicals, fertilizers, pesticides, sediment, and animal waste, which can then enter rivers, lakes, and other water bodies, making them polluted.
Polluted runoff can also cause soil erosion, harm aquatic life, and contaminate drinking water sources. Therefore, it is important to manage runoff properly by using practices such as rain gardens, bioswales, or green roofs that help absorb and filter runoff, reducing its potential to cause pollution.

What is a strategy prokaryotes to help them survive
Answer:
What is a strategy prokaryotes to help them survive?
Most prokaryotes have cell wall which helps them to protect itself against hypo and hyper-osmotic. also some bacteria have endospore which helps them to survive as well
Explanation:
Prokaryotes use various strategies to survive harsh conditions, such as protective cell walls, forming endospores, and diverse metabolisms allowing them to utilize substances like hydrogen sulfide. The CRISPR-Cas immunity system and specialized adaptations like growth appendages for oxygen sensing further highlight their resilient nature.
Survival Strategies of Prokaryotes:
Prokaryotes have developed various survival strategies to adapt to a wide range of environmental conditions, making them incredibly versatile organisms. For example, nearly all prokaryotes possess a cell wall, which is a critical structure that provides protection in hypo- and hyper-osmotic situations. Additionally, certain soil bacteria can form endospores that are capable of withstanding extreme heat and drought, ensuring their survival during unfavorable conditions. These resilience mechanisms contribute to the dominance of prokaryotes in both terrestrial and aquatic ecosystems.
Moreover, prokaryotes exhibit a broad range of metabolisms that determine their habitats. They can utilize various substances, such as hydrogen sulfide (despite it being toxic to animals), to produce ATP for energy. Furthermore, some prokaryotes possess unique mechanisms such as CRISPR-Cas systems for providing immunity against viral infections. Others, like the bacterium Shewanella, demonstrate specialized adaptations like growing long appendages to seek out limited oxygen supply in their deep-sea habitats, a process that also allows them to digest toxic waste and even generate electricity.
These adaptive strategies firmly establish prokaryotes as vital components of the biosphere, contributing significantly to life-supporting processes and displaying remarkable abilities to adjust to and thrive in diverse and sometimes extreme environmental conditions.

Exploring different types of relationships in nature through a short story.
Explanation:Short Story Showing Different Relationships in NatureOnce upon a time, as I wandered through a dense forest, I came across a fascinating ecosystem teeming with life. In this diverse environment, I encountered various organisms that displayed different types of relationships.
Predator-Prey Relationship:I witnessed a fierce lion stalking a herd of zebras. The lion skillfully used its speed and stealth to capture and feed on the zebras, exemplifying a predator-prey relationship. This relationship showed how one organism hunts and consumes another as its food source.
Commensalism:Further along my path, I noticed a bird perched on the back of a grazing buffalo. The bird benefited by catching insects disturbed by the buffalo's movements, while the buffalo remained unaffected. This mutual association between the bird and buffalo exemplified a commensalism relationship.
Mutualism:As I ventured deeper into the forest, I encountered a unique partnership between a flowering plant and a hummingbird. The plant provided nectar, which served as nourishment for the hummingbird, while the bird unintentionally pollinated the plant as it drank the nectar. This symbiotic relationship showcased mutualism, where both organisms benefitted.
Parasitism:Finally, I stumbled upon a group of grazing cattle plagued by parasitic ticks. These tiny arthropods latched onto the cattle and fed on their blood, harming the cattle while obtaining sustenance for themselves. This parasitic relationship demonstrated how one organism benefits at the expense of another.
Through these encounters, I observed contrasting relationships in nature, from the predatory nature of the lion and the zebra to the mutually beneficial cooperation between the flower and the hummingbird. Each relationship played a crucial role in maintaining the delicate balance of the ecosystem.

If carbon dioxide is removed from a plant’s environment, what would you expect to happen to its production of glucose
Answer:
It won't be able to produce glucose anymore or it will significantly drop. During the process of photosynthesis, plants take in CO2, water, and energy from the sun. They use things to make food. The chloroplast is responsible for taking in that energy from the sun and make its own food. CO2 can also affect the temperature of the plant as well as the environment. Plants need CO2 in order to go through photosynthesis. The plant could die and glucose won't even be produced anymore.

Describe the process of homeostasis when body temperature rises too high. ASAP please <3
Answer:
"If blood temperature rises too high, this is sensed by specialized neurons in the hypothalamus of the brain. ... As these blood vessels dilate, more blood flows close to the body surface and excess heat radiates from the body."
Explanation:
just do this answer, I'm sure
good luck
A high body temperature causes the blood vessels to widen, the sweat glands to release liquid, and the body loses heat. The temperature of the body returns to normal as heat is dissipated into the surrounding air.
What is role of homeostasis in human body?Specialized neurons in the brain's hypothalamus can detect when blood temperature gets too high. More blood flows close to the body's surface when these blood arteries widen, and the body releases more heat.
The body must do numerous tasks continuously to maintain homeostasis. Its primary responsibilities include metabolizing food, reacting to changes in the body's environment, exchanging materials with the environment.
