Answer:
Ozone in the stratosphere is helpful; it absorbs harmful UV-B and UV-C waves from the sun, which are both known to cause sunburn and skin cancer. On the other hand, ozone in the troposphere is very damaging; it is a major component of photochemical smog, and it causes eye, nose, and lung irritation and aggravates asthma.

How does energy drive the water cycle?
Select one:
-Energy from the sun heats liquid water, forming water vapor.
-Energy from Earth’s interior (mantle) heats liquid water, forming water vapor.
-Energy from the sun heats condensed water, forming precipitation.
-Energy from Earth’s interior (mantle) melts solid water, forming liquid water.
Answer:
Energy from the sun heats liquid water, forming water vapor
Explanation:
The heat from the sun evaporates water, which makes clouds and then causes rain. The cycle then repeats after the sun comes out again.

Answer:
Over millions of years, the shape of mountains on Earth’s surface can change to low hills and then to rolling plains. These changes are most likely caused by weathering and erosion.
These changes are most likely caused by weathering and erosion
What is weathering and erosion?weathering is the breakdown or dissolution of rocks and minerals. After a rock has been broken down, the bits of rock and minerals are carried away by erosion.
Erosion is a geological process in which natural forces like as wind and water wear away and transfer earthen materials.
How does weahering and erosion cause breakdown of large hills?weathering and erosion speeds up the process of breaking down of a mountain. Erosion speeds up tectonic processes beneath the mountains by lowering the weight of the mountain range. Wind, rain, and ice increase at higher elevations and directly effect the weathering and erosion process, causing mountain tops to weather more quickly.Hence the mountain will change into a valley over many years followed by eroding into rolling plains.learn more about Weathering and erosion here:

Describe the steps by which oxygen moves from the environment to cells in the body and carbon dioxide moves from cells to the environment.
Oxygen is inhaled into the lungs for gaseous exchange, to occur between the blood and the alveoli, where oxygen diffuses into the blood; then, binding to haemoglobin of the red blood cells, which is carried away to cells in the body for respiration and CO2 diffuses out of the blood, to be exhaled.

15. If out of 100 offspring, 74 are purple flowered and 26 are white, what were the likely genotypes and
phenotypes of the parents if this is a simple monohybrid cross?
Answer:
so it would be a 3 : 1 ratio.
Explanation:
The probable genotypes of the parents is Pp (Purple). When we will cross the two heterozygous purple flowers we will get the purple and white coloured flowers
The ratio would be 3:1. The parents' likely genotypes are Pp (Purple). Purple and white colored flowers will result by crossing two heterozygous purple blooms.
What are Genotypes and Phenotypes?The type of variant existing at a specific locus (i.e., region) in the genome is scored by what is known as a genotype. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb might be employed to denote a certain gene variant.
The term "phenotype" refers to an organism's observable qualities, which are a multifactorial result of hereditary attributes and environmental factors. The physical, biochemical, physiological, and behavioral characteristics of an organism make up its phenotype.
Pp is the likely genotype of the parents (Purple). In the example presented above, combining two heterozygous purple blossoms will produce flowers that are both purple and white.
Thus, the ratio would be 3:1. The parents' likely genotypes are Pp (Purple). Purple and white colored flowers will result by crossing two heterozygous purple blooms.

Answer:
I would say habitat planner and land planner
Explanation:
I picked habitat planner and land planner to do because I am an artist and a designer and I know how to put things together properly and for people to be like "Wow this is a beautiful piece right here" I would make it beautiful for the person's eyes when doing this you need to think about how a person might look at it I would want them to gasp and stare astonished and amazing and I could do that I've been practicing design for awhile now so If I were to pick these two things it is what I would do and also I really like nature and designing things with nature that others haven't thought about because it shows my creativity and ability to look beyond the point of just seeing.
If I could choose any career in ecology, I would pursue a career as a habitat planner.
Who is a habitat planner?This profession would allow me to contribute to the conservation and restoration of natural habitats, ensuring the well-being of various species and ecosystems. As a habitat planner, I would have the opportunity to assess existing habitats, develop conservation strategies, and collaborate with stakeholders to implement effective management plans.
I am passionate about the preservation of biodiversity and creating sustainable environments, and this career would allow me to make a tangible impact on the natural world. Additionally, working as a habitat planner would provide a dynamic and interdisciplinary work environment, where I could apply my knowledge of ecology, land management, and environmental policy to address complex conservation challenges.

The answer is D) fruits and vegetables that do not spoil easily
You can eliminate B and C, since those two are clearly not positive outcomes (I doubt anybody would want more viruses and fewer animals on Earth!)
A is a little less obvious; however, genetically manipulating crops to have a slower growth rate would be a negative effect on the harvest (and it's probably something most farmers wouldn't want to do anyway.)
So, the answer is D. This makes sense, since having fruits and veggies that don't spoil easily would be a benefit so they can have longer shelf lives.

Here is what your equation looks like
[tex]Population density = 200/50^2[/tex]
Calculate that and you get 0.08 people per square mile.
Assume all of the presynaptic synapses identified produce epsps. If two of these synapses fired simultaneously, which synaptic combination brings the initial segment closest to threshold based on spatial summation? click on the appropriate synapses.
Based on spatial summation, the synapses closest to each other will brings the initial segment closest to threshold.
What are Excitatory Post-Synaptic Potentials, EPSPs?Excitatory Post-Synaptic Potentials, EPSP, are postsynaptic potential changes that are induced by neurotransmitters which depolarizes the cell, and hence increases the likelihood of initiating a postsynaptic action potential.
Based on spatial arrangement, the summation of two simultaneously fired synapses that is greater than or close to threshold potential will produce an action potential.
Therefore, the synapses closest to each other will brings the initial segment closest to threshold.
