D) social construction.
E) binary arrangement.
Sociologists argue that the division of the human population into two distinctive and mutually exclusive categories, male and female, is best understood as a biological fact.
The division into these two major categories as male or female is mainly due to the biological and the physiological characteristics produced in both male and female.
Although in some cases, it may be argued that they are not mutually exclusive as there are some who have both.
Nevertheless, the above mentioned characteristics are just used to differentiate between a male and a female in humans and as well an individual self-concept of being a male or a female.

Digestion
Most of the digested foods are absorbed in the small intestines of humans.
Undigested foods, otherwise known as feces are not absorbed but are instead moved into the caecum of the large intestine through a structure known as ileocaecal valve.
The valve prevents the backflow of the feces into the small intestine and the feces are stored in the rectum pending the time they are defecated.

5. Why do you think it's important to look at the impact on the ecosystem as a whole, instead of just the individual"?
Answer:
Ecosystem Services are the benefits nature provides to human well-being. The term is frequently thrown around in academic circles, but why should you care about them?
Although the term is quite new, our connection to nature is not. We depend on nature for our survival - without healthy ecosystems, our drinking water isn’t clean nor is the air we breathe. We also enjoy nature... studies show that people who spend time in nature tend to be happier than those that don’t. It can even act as a natural anti-depressant. With industry and urban sprawl expanding at unprecedented rates, Ecosystem Services attempt to translate the benefits we receive from nature into economic terms so we can better understand the trade-offs we are making between nature and industrial development.
This brings us to the reasons why we feel Ecosystem Services are important to each and every person:
1. Boundless Benefits
Understanding nature in economic terms, while not perfect, allows us to put everything into the same comparison unit. Despite nature being such an integral part of the human existence, it is sometimes an afterthought in today’s economy. Nature and money are often on competing terms, so to make a more level playing field, environmental economists have tried to bridge this gap by placing a monetary value on the benefits nature provides.
A recent study estimated the combined benefits of nature to people at well over $100 USD trillion per year. To put this in perspective, the top 50 most profitable companies globally combine to make just under $10 USD trillion per year.
Valuing nature in a way that can speak to decision makers, may help promote conservation efforts in the future. It brings nature back into the cost-benefit discussion in a way that can be easily understood.
2. The Foundation For Sustainable Development
Ecosystem Services help measure the true cost of industrial development. Often, the impact industrial development has on the economy and job creation overshadows the cost it will have on surrounding lakes, forests, keystone species, and so on. Assigning a dollar value to these lakes and forests, and the Ecosystem Services they provide, helps adjust the cost benefit analysis by evaluating the negative effects development will have on the natural environment.
Companies have also started to use Ecosystem Services in conservation offset planning, where they can buy and sell credits to offset a development or set aside land to meet a specific offset. Sustainable development supports the maintenance of a healthy economy while also protecting the ecological process for future generations.
3. Essential For Our Survival
Whether you live in rural Newfoundland or downtown Los Angeles, your dependence on Ecosystem Services is the same. As a society, we depend on healthy ecosystems to do many things; to purify the air so we can breathe properly, sequester carbon for climate regulation, cycle nutrients so we have access to clean drinking water without costly infrastructure, and pollinate our crops so we don’t go hungry. As the world’s population continues to grow, so too does our dependence on healthy ecosystems to provide the necessities essential to our survival.
Don’t we all want to leave the planet in a good condition for our successors? Ecosystem Services valuation and assessment is one way to help make this happen. By clearly understanding their value, we can make the best and most informed decisions about how to manage our landscape to ensure this value isn’t lost.

Answer:
Answer:
Explanation:
Answer:
Photosynthesis: photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.Coronary heart disease is the main cause of death in our country. The following factors can increase the risk of an individual contracting this disease:
-smoking
-unbalanced diet
-unhealthy lifestyle
Explain how these factors can contribute to coronary heart disease.
Smoking :-
The coronary arteries inside us are responsible for supplying our heart muscles with O₂ rich blood. When people smoke, plaque builds up in the arteries & the O₂ rich blood will not get supplied to the hear muscles causing atherosclerosis / coronary heart disease.
Unbalanced Diet :-
Eating an unhealthy diet which is high in cholesterol & fats also causes atherosclerosis (coronary heart disease). Too much salt in the diet can also raise blood pressure which is another factor responsible for this disease.
Unhealthy Lifestyle :-
Unhealthy lifestyles like not exercising at all & being obese lead to atherosclerosis (coronary heart disease).

C.
helicase
D.
RNA primase
E.
topoisomerase
Answer:
C
Explanation:
because it separate the strands so it is affected so it cannot unwind the strand of the DNA double helix .
hope this helps :)
As in the given scenario, the enzyme DNA helicase is affected, the correct option is C.
What is the function of DNA helicase during DNA replication?Helicases are a type of enzyme that is thought to be essential to all organisms. Their primary function is to unpack the genetic material of an organism.
Helicases are motor proteins that use ATP hydrolysis to move directionally along a nucleic acid phosphodiester backbone, separating two hybridized nucleic acid strands.
DNA helicases are required during DNA replication because they split double-stranded DNA into single strands, allowing each strand to be copied independently.
During DNA replication, DNA helicases unwind DNA at locations known as origins, which are where synthesis will begin.
If the DNA strands were unable to separate during the replication process, DNA helicase is the enzyme most likely to be affected.
The enzyme that unwinds the DNA and creates the replication bubble is known as DNA helicase.
Thus, the correct option is C.

This would trap the oxygen produced in photosynthesis and kill the plant. D) This would help the needles gather more sunlight energy, increasing photosynthesis. Energy Transfer
Answer:this would also stop gas exchange and further limit photosynthesis
Explanation: did this on USA test prep and got it right
This would also stop gas exchange and further limit photosynthesis. Therefore, option B is correct.
What is the mechanism of opening and closing of stomata?The content of cell sap is reduced as a result of the conversion of the organic acids into starch. This causes water to exit hard cells, and a decline in their turgor causes the stomata to close. Stomata therefore open throughout the day and close at night.
The pH of the guard cells controls stomatal opening, according to the starch sugar interconversion theory of stomatal opening. In neutral or alkaline pH, stomata open. When the guard cells are open during the day and closed at night, they contain starch during the day.
Under dehydration circumstances in the winter, stomata may close to reduce water loss for the tree. This would also stop gas exchange and further limit photosynthesis. Therefore, option B is correct.

five (5) kidney diseases their symptoms and their effect
Answer:
Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:
toxic exposure to environmental pollutants or certain medications
certain acute and chronic diseases
severe dehydration
kidney trauma
Your body becomes overloaded with toxins if your kidneys can’t do their regular job. This can lead to kidney failure, which can be life-threatening if left untreated.
Usually, someone with kidney failure will have a few symptoms of the disease. Sometimes no symptoms are present. Possible symptoms include:
a reduced amount of urine
swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste
unexplained shortness of breath
excessive drowsiness or fatigue
persistent nausea
confusion
pain or pressure in your chest
seizures
coma
Symptoms of early-stage kidney disease may be difficult to pinpoint. They’re often subtle and hard to identify. If you experience early signs of kidney disease, they may include:
decreased urine output
fluid retention that leads to swelling in limbs
shortness of breath
A sudden loss of blood flow to your kidneys can prompt kidney failure. Some conditions that cause loss of blood flow to the kidneys include:
a heart attack
heart disease
scarring of the liver or liver failure
dehydration
a severe burn
an allergic reaction
a severe infection, such as sepsis
High blood pressure and anti-inflammatory medications can also limit blood flow.
When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways, such as:
prostate (a most common type in men)
colon
cervical
bladder
Other conditions can interfere with urination and possibly lead to kidney failure, including:
kidney stones
an enlarged prostate
blood clots within your urinary tract
damage to your nerves that control your bladder
Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys.
The following may cause ischemia:
severe bleeding
shock
renal blood vessel obstruction
glomerulonephritis

Answer:
Organelles in animal cells include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles. Ribosomes are not enclosed within a membrane but are still commonly referred to as organelles in eukaryotic cells. Membrane-bound organelles. Membrane-bound organelles are cellular structures that are bound by biological membrane. Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.
Have a great day friend! :D
Answer:
Organelles play an important role in a variety of cell processes. The nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, vesicles, and vacuoles are all organelles found in animal cells. Although ribosomes are not surrounded by a membrane, they are nonetheless referred to as organelles in eukaryotic cells.
Explanation:
ORGANELLESAn organelle is a specialized subunit of a cell that has a defined role in cell biology. The name organelle stems from the idea that these structures are sections of cells, similar to how organs are parts of the body, therefore the diminutive suffix -elle. Organelles are either independent lipid bilayer-enclosed functional units (also known as membrane-bound organelles) or spatially distinct functional units without a lipid bilayer surrounding them (non-membrane bound organelles). Although most organelles are functional units within cells, some functional units that extend outside of cells, such as cilia, the flagellum and archaellum, and the trichocyst, are often referred to as organelles.Learn more about Organelles here
