Answer:
From Radioactivity
N/N° = (1/2)^t/t•
Where
N=Remaining Mass
N°=Initial Mass
t=Time of decay Or Time spent on decayingb
t•=Half life
N=N°(1/2)^t/t•
N=16(1/2)^21.6/7.2
N=16(1/2)³
N=16(1/8)
N=2g.

Answer:
Helping others is the characteristics of human beings.
Explanation:
It is very important to stand up for others because helping others is the property of human beings. Those people who stand for other people and help them in their difficult situation, these people helped by the God and these people get happiness and prosperity in their life while on the other hand, those people who can't stand for other people will also can't receive help from others in difficult and needy situation. This stand also shows your courage and bravery to the opposite party.

Explanation:
Your lab manual says that the nutrient agar control plate in this experiment, is "a comparison for growth quality." Explain why the results on the nutrient agar plate are necessary to justify your conclusions about the mannitol salt agar plate\.\*
Answer:
Nutrient agar lets us know about the presence/absence of any kind of bacteria.
Mannitol salt agar let us know about the presence/absence of osmotolerant bacteria.
The difference between them lets us know which bacteria are osmotolerant and which ones are not.
Explanation:
The mannitol salt agar is useful to identify organisms with specific traits. It is a selective medium that only allows the growth of osmotolerant cells. It is used to identify bacteria such as Staphylococcus aureus.
The comparison between nutrient agar and mannitol salt agar is significant because it gives more information about the bacteria type. If no cell grows in these two mediums means that there are no bacteria at all. But if cells can grow in the nutrient agar and not in the mannitol salt agar, it means the growing bacteria are not tolerant to salty mediums. They are not osmotolerant.
A comparison between the presence/absence of bacteria growing in each medium lets us know which species are osmotolerant and which ones are not.
describe the "body " structure of a fungus
Answer:
A mass of hyphae make up the body of a fungus, which is called a mycelium (plural, mycelia). The hyphae of most fungi are divided into cells by internal walls called septa (singular, septum). Septa usually have little pores that are large enough to allow ribosomes, mitochondria and sometimes nuclei to flow among cells.

Which of the following variables did Pasteur change in his experiment to test the hypothesis of
spontaneous generation?
The variables that Pasteur changed in his experiment to test the hypothesis of spontaneous generation is the shape of the flask
Pasteur in 1856 was known for his contribution to the science world through the study of the causes of spoilage in beer and wine. He demonstrated his knowledge from his discovery of the properties of fermentation by microorganisms.
He demonstrated and discovered that airborne microbes were the cause of food spoilage not a spontaneous generation with his swan-neck flask experiment. He went ahead with a suggestion that if microbes were responsible for food spoilage and fermentation, they could also be responsible for causing infection and this was the foundation for the germ theory of diseases.
In the later year, Pasteur established his previous experiment with a new one. In this new experiment, he made several flasks with long, twisted necks called the swan-neck flasks where he boiled broth and sterilized it. The essence of the swan neck design is to inhibit the introduction of airborne microorganisms into the flask by trapping them between the twists and bends of the flask and also to allow the exchange of air in the flask with the surrounding air.
Based on the theory above, we can conclude that the variables that Pasteur changed in his experiment to test the hypothesis of spontaneous generation is the shape of the flask

C. Allow the individual to survive better and reproduce more in the environment
D. Allow the individual to have fewer diseases and not get sick

1. Allow the individual to survive better and reproduce...
2. Hooves are better equipped for environments with plains.
3. An insect species with high reproduction rates and a significant...
4. Genetic variation
5. Higher reproduction rates
Explanation:
Good luck ♡
In order for a trait to be considered a competitive advantage, the trait must allow the individual to survive better and reproduce more in the environment. So, the correct option is C.
What do you mean by Trait?
A trait may be defined as the appearance or a manifestation of characters. It is also known as Phenotypes.
To understand better about competitive advantage, an individual must carry the trait of relative fitness which defines the relative survival and relative reproduction of an individual.
Therefore, in order for a trait to be considered a competitive advantage, the trait must allow the individual to survive better and reproduce more in the environment.

Bengal Tigers (Panthera tigris tigris) have coat colors that are either golden (the dominant trait) or white. In examining a population of Bengal Tigers found in India, researchers found that the white tiger frequency was 4%. If this population had 200 tigers with 10 heterozygotes, calculate the actual genotype frequency of the heterozygotes in the tiger population.
Answer:
5%
Explanation:
Frequency of white tigers = 4%
population of tigers = 200
number of heterozygotes = 10
Determine the actual genotype frequency of Heterozygotes
frequency of heterozygotes = Number of heterozygotes / population
= ( 10 / 200 ) * 100
= 0.05 * 100 = 5%
list two ways that the fungal life cycle is different from the animal life cycle
Answer:
In some aspects, the fungal life cycle is contrary to vertebrates. In most fungi, hyphae with haploid nuclei are the dominant stages. Two nuclei from neighboring hyphae merge into a diploid zygote during sexual reproduction. The zygote undergoes meiosis after a brief period of time.
Explanation:
The haploid (called spores) cells produced from this process become new haploid hyphae. In the bread mold, the haploid hyphae form many haploid springs which can go to other places and lead to new hyphae. Most fungi can also reproduce asexually. Note that mitosis (why?) causes these spores. This asexual reproductive process is a distinct cycle and is more widespread in most fungi than the sexual life cycle. The characteristic black dots found on molten bread, for example, are clusters of asexually produced spores. See this animation which describes the bread mold life cycle.
Unique and complex fungal life cycles. Fungi breed sexually either cross-fertilization or self-fertilization. The Haploid fungus has gametes at tips and generates hyphae. There are two different types of matches (marked as "+ type" and "– type").

Hydroelectric power is much cleaner and safer source of energy compared to coal, instead of digging out the Earth, we simply use its natural flowing water. Using hydroelectric power also ensures we do not suffer from the smog and harmful chemicals emitted by coal powered plants. A cleaner environment ensures happier people, a healthier ecosystem, and overall a better place to live. Not all areas can harness local water systems like our Town, we are lucky to even have the opportunity to live on hydroelectric power. Due to this, we can simply use the coal we mine and sell it to other less fortunate towns, while not needing to worry about our electricity or coal economy.
