Answer:
The main reason why these people live to an advanced age is better medical care. But average life expectancy is also increasing because the rate of infant mortality has fallen across the world.
The more in depth answer is under the 'Explanation' part.
Explanation:
List of reasons for increased life expectancy in the United States.
-Healthcare.
-Sanitation.
-Nutrition.
-Working conditions.
Life expectancy has increased rapidly since the Age of Enlightenment. In the early 19th century, life expectancy started to increase in the early industrialized countries while it stayed low in the rest of the world. This led to a very high inequality in how health was distributed across the world. Good health in the rich countries and persistently bad health in those countries that remained poor. Over the last decades this global inequality decreased. No country in the world has a lower life expectancy than the countries with the highest life expectancy in 1800. Many countries that not long ago were suffering from bad health are catching up rapidly.Now Humans are living longer around the world. While there have been obvious ups and downs, life expectancy at birth overall has been steadily increasing for many years. It has more than doubled in the last two centuries. This increase was previously driven by reductions in infant mortality
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].

How does energy move from place to place ?
Answer:
Energy can be moved from place to place by moving objects, or through sound, light, or electrical currents. Energy can be converted from one form to another form. Kinetic energy can be distinguished from the various forms of potential energy. This is how energy moves. I hope it helps!!

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.

& Milk wood plants are essential for monarch butterfly survival. The butterflies drink the nectar from milkweed
flowers. The female monarchs lay their eggs only on milkweed plants, and the monarch caterpillars rely on the
milleweed plant as its primary food source. Milkweed produces a poisonous toxin that the caterpillars are able to
collect in specialized sacs, which in turn makes the caterpillars poisonous to predators. Milkweed plants are
pollinated by monarch butterflies as well as other insects. Which of the following best describes the resulting
daptations found in milkweed plants and monarch butterflies?
cevolution
cooperation © parasitism
mimicry
Answer:
Coevolution
Explanation:
There is a symbiotic relationship between them because the plants get pollinated and the butterflies get protection. Their relationship can also be described by the term mutualism.

Mushroom rocks are formed by ___________________
Answer:
wind erosion
Explanation:
The rocks are deformed in a number of different ways: by erosion and weathering, glacial action, or from a sudden disturbance. Mushroom rocks are related to, but different from, yardang. A mushroom rock, rock pedestal, or gour is a typical mushroom-shaped landform that is formed by the action of wind erosion.
mushroom rocks are corn as fungi
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.

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.
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.

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
