Alan lives in an area that has a huge park. Moreover, there is good quality of air and water in his region. What is the possible consequence of such conditions?
A.
premature deaths
B.
asthma
C.
cardiovascular diseases
D.
high life expectancy
Answer:
D. High Life Expectancy
Explanation:
Air pollution lowers life expectancy and causes tons of premature deaths in areas. The area that Alan lives in has good air quality which means that there is obviously going to be a increase in life expectancy. If water quality is bad in an area it can cause chronic illnesses (such as cancer), gastrointestinal illnesses, and even effect the nervous and reproductive systems in a bad way. So the fact there is good water quality in the region the area Alan lives in, he is pretty much guaranteed for higher life expectancy. Therefore the best answer is Option D.
Design a laboratory-based experiment to test the hypothesis that algae need light to grow.
The same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.
What is algae growth?The growth of algae is the process by which the organism increases in size. Now we know that that the algae is photosynthetic hence light must be required for its growth.
In order to verify this, the same algae is subjected to conditions in which one is exposed to light and another is not exposed to light while the nutrients in the both systems are kept the same.
The results of this experiment must confirm that the algae exposed to light grows better than the algae that was not exposed to light.

O When a scientist finds a new way to test a hypothesis, the original theory is made into a law.
Answer:
Theories may be revised over time as information is discovered or technology is developed.
Explanation:
A scientific theory is a term used when a statement tries to explain a natural phenomenon of nature based on scientific facts. In short, a theory is the representation of a set of hypotheses that was confirmed through an experiment and that tries to explain a phenomenon, but leaves room for revisions and updates to its explanation.
For this reason, we can say that theories are reformulated, revised and even discredited, when the advancement of scientific knowledge and technology allows the creation of new studies that show a different explanation and more consistent with reality.

How is the law of conservation of mass applied to ecology?
In ecology, the law of conservation of mass is applied by the principle of taking energy from the lower trophic levels and passing it to the higher trophic level by any means.
What is the law of conservation of mass?The law of conservation of mass states that the actual mass in an ecosystem is neither created nor destroyed. Overall remains constant in a system.
In ecology, it illustrates that when an organism is ingested by other organisms, its mass is conserved. Some of the organisms may also be dependent on the waste products like urine and feces to make proteins and other compounds.
Therefore, the energy or mass is neither lost in any form. It simply is taken by other organisms through any means.

What are the structures and functions of the tissues lining the respiratory organs?
What is the function of water on the inner surfaces of alveoli?
What is the function of surfactant on the inner surfaces of alveoli?
What are the microscopic structures within the lungs?
What important information did you learn about from this video?
Answer:
1-The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
2-The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants.
3-The main function of surfactant is to lower the surface tension at the air/liquid interface within the alveoli of the lung. This is needed to lower the work of breathing and to prevent alveolar collapse at end-expiration.
4-The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic. The bronchioles eventually end in clusters of microscopic air sacs called alveoli.

What are the fungal hyphae?The fluttery filaments that make up multicellular fungi are called hyphae. As they consume resources from a food source, they release enzymes. Chitin makes up the rigid cell wall of hyphae. In pursuit of more food sources, they spread out from a tip and continue to expand.
The substrate is broken down by digestive enzymes secreted by the hyphae, which makes it simpler for the fungus to absorb the nutrients it contains. The fungus has a very wide surface area compared to its volume, which indicates that it is in close contact with its surroundings.

Answer:
natural selection ; homologous
The population of birds with large beaks will increase on the island (1st listed) ; The trait for large beaks will be passed on to future generations through natural selection. (3rd listed)
B) 80 /200
Explanation:
Giraffes evolved over many generations to have long necks. Giraffes that had longer necks were more likely to survive than giraffes with shorter necks because they had better access to food. This is an example of natural selection / survival of the fittest.
(the "fittest" [most beneficial/practical] trait is surviving and getting "selected" by nature)
Giraffes are also vertebrates, like humans. In fact, despite their different neck sizes, humans and giraffes have exactly seven vertebrae bones in their neck. This similarity suggests human and giraffe necks are homologous [structures]

...' What are two ways the decrease in seed availability will affect the population of birds on the island?'
The population of birds with large beaks will increase on the island.
[This is the concept of natural selection / survival of the fittest, they have the most abundant resource [because they are able to eat what is abundant on the island, compared to smaller birds that have a larger decrease in food availability] ]
The trait for large beaks will be passed on to future generations through natural selection.
[If these birds / and this trait survive, they will be able to have offspring [future generations]. Birds with a low survival percentage will be less successful in mating, and will likely not produce the same quantity of offspring that will carry on their traits to future generations.]

frequency of an allele:
population: 100
frequency recessive [homozygous bc 2 same recessive alleles]: 25 (tt)
frequency dominant homozygous: 45 (TT)
frequency heterozygous dominant: 30 (Tt)
total alleles: 100 [our population] times 2
100 · 2 = 200
total alleles: 200
number of times we have [dominant] T:
30 from each heterozygous dominant (Tt)
2 · 45 (TT has two T's) = 90 from homozygous dominant
30 + 90 = 120
number of times we have [recessive] t :
30 from each heterozygous dominant (Tt)
2 · 25 (tt has two t's) = 50 from each homozygous recessive
30 + 50 = 80
So, we know that the frequency of recessive allele [t] is 80 / 200
[80 out of 200]
So, option B) 80 / 200 is correct
(this = 0.4)
(and dominant [T] is 120 / 200; I say this to show that recessive frequency and dominant frequency are calculated the same way!!)
