How has human land use impacted the environment?
the answer is for anyone who needs it Ways that humans impact the environment is pollution and deforestation which can cause global warming and mass extinction. When humans pollute the earth they slowly start to cause global warming. When we burn fossil fuels to generate electricity, drive our cars, and power our lives we release heat trapping gasses into the atmosphere which slowly makes the world warmer. Deforestation get rid of some of our oxygen supply but it also can lead to mass extinction. When we cut down and burn trees it gets rid of animals homes. If the animals homes get destroyed they are forced to compete with other animals for their survival. Therefor one animal will survive while the other one dies and if this process occurs frequently it leads to many animals going extinct.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
Human activities causes extreme adverse conditions in the environment which resulted eben in the eventual devastation of some species from earth. The selfish actions of humans causes all kinds of pollution in nature.
What are human impacts?The term "human impact on the environment" (or "anthropogenic impact") refers to alterations to biophysical environments as well as to ecosystems, biodiversity, and natural resources.
Environmental changes made to meet societal requirements have negative repercussions. global warming, environmental deterioration (such as ocean acidification), mass extinctions and biodiversity loss, ecological catastrophe, and ecological collapse, to name only a few.
Population expansion, overconsumption, overexploitation, pollution, and deforestation are some human activities that harm the environment on a global scale.
It has been suggested that some of the issues, such as global warming and biodiversity loss, pose grave hazards to the existence of the human species.

This picture shows a cross-section of a blood vessel. The diameter of the
lumen in Figure 10 is 25.0 mm. What is the actual diameter of the lumen of
this blood vessel?
lumen
magnification X8
3.1 x 10-2m
3.1 x 10-3 m
O 2.0 x 10-2 m
2.0 x 10-3 m
Answer:
B. 3.12 x [tex]10^{-3}[/tex] m
Explanation:
From the given picture, it can be deduced that;
the diameter of the image of lumen = 25.0 mm
= 25.0 ÷ 1000
= 0.025 m
And,
magnification = [tex]\frac{diameter of the image of lumen}{actual diameter of lumen}[/tex]
But magnification = 8,and diameter of the image of lumen = 0.025 m.
So that;
8 = [tex]\frac{0.025}{actual diameter of lumen}[/tex]
⇒ actual diameter of lumen = [tex]\frac{0.025}{8}[/tex]
= 0.003125
Actual diameter of lumen of the blood vessel is 3.12 x [tex]10^{-3}[/tex] m.

Answer:
Pulmonary blood vessel
Explanation:
The pulmonary blood vessel carries low oxygen blood to the lungs and brings high oxygen blood back to the heart.
More specifically, the pulmonary artery carries low-oxygen blood to the lung from the right ventricle of the heart. The blood becomes oxygenated in the lung and the oxygen-rich blood is taken back to the left atrium of the heart by the pulmonary vein.

Which type of reproduction is responsible for genetic variation?
Answer:
sexual reproduction
Explanation:
Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.
Other reproductions like asexual, budding or fragmentation don't produce genetic variation.
The type of reproduction is responsible for genetic variation is - sexual reproduction.
Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.
Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

You are comparing the density of sea water to the density of fresh water. (Remember,
density is mass divided by volume.) Describe how you could determine the density of
sea water, including the names of the equipment needed to make the required
measurements.
Answer:
To know and compare the difference between the density of the fresh water and salt water or sea water require a graduated cylinder, balance, and weighing machine. The graduated cylinders are the containers that have markings on them to measure the volume of the liquid.
First, fill the cylinder with 1000 ml of fresh water which is the measure of the volume. now weight the cylinder filled with the fresh water and then find the difference between filled and empty container divide the mass of the fresh water by its volume, the result is the density of fresh water.
Repeat the process with salt water or sea water. The answer would be sea water has more density than fresh water.

Iron rich deposits that formed about 2 billion years ago have red layers. Layers formed before then were not red. The red layers formed when oxygen made during photosynthesis reacted with iron molecules in the ocean. The oxidized iron formed layers of sedimentary rock
. Which BEST summarizes this phenomenon?
A. The lithosphere changed the atmosphere. B. The hydrosphere change the atmosphere.
C. The atmosphere change the biosphere.
D. The biosphere change the lithosphere
Answer:
D. The biosphere change the lithosphere
Explanation:
The red formed due to oxygen which is produced by plants in the process of photosynthesis. This oxygen then reacted with iron atom and formed oxidized iron layers of sedimentary rock. So here plants are responsible for the formation of these layers and we considered plants as part of biosphere so we can say that biosphere is responsible for the change of lithosphere.
Answer:
D. The biosphere change the lithosphere

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.
Answer:
Through meiosis
Please find the description below
Explanation:
Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.
The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.
Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).
Compare and contrast the elevated temperature of someone who is exercising vigorously and someone who has an infection
Answer:
Due to muscle contraction and fighting of white blood cells.
Explanation:
Exercise increases the temperature of body because about 20% of the energy produced in contracting muscles is used for muscle contraction while the remaining 80% is converted into heat energy, as a result body's temperature increases whereas a person who has infection also experience high body temperature because the body work faster to fight against the infection that leads to high temperature.
