Answer:
The Proton and neutron has the same mass because the number of protons can differ from the number of electrons which give off different charges and can result in a different weight and amount of charge whether its negative or positive
describe how the force of gravity from Earth could affect nearby Apollo asteroids and explain how the effect of Earth’s gravity could change the orbital motion of an Apollo asteroid.
Gravity pulls objects toward Earth at a rate of 9.8 m/s2. Weight is the result of gravity's pull on a mass on Earth's surface.
The force of gravity from the Earth could affect nearby the Apollo asteroids and this gravitational force is responsible for pulling the objects towards itself which could change the orbital motion of an Apollo asteroid.
What is the Apollo asteroid?Apollo asteroids are also called as the near-earth asteroids. These are a major source of the meteorites which occasionally fall to the earth. Asteroids with the orbits that approach the earth, are passing inside the perihelion of the Mars, and these are called as Amors. Those that cross the orbit of the earth are called as the Apollo asteroids.
Gravitational force is the force which pulls all the objects in the universe towards each other on the planet and in its orbit. On the Earth, gravity pulls all the objects downward towards the center of the planet.

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%

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.
Compression of mortality is the extent to which an organ can preserve essentially normal function despite decreasing cell number or cell activity. Group of answer choices True False
Answer: False
Explanation:
Compression of mortality refers to the reduction over time with regards to the variance of the age of people at death.
The extent to which the organ can help in preserving normal function despite the fact that there's a reduction in the number or cell activity is referred to as compression of morbidity.
When morbidity is compressed, it should be noted that individuals can be expected to live healthier and longer as well.
Therefore, the statement is false

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

Question 7
In prokaryotic cells, the ribosomes:
O A. synthesize proteins
O B. synthesize nucleic acids
O C. synthesize sugars
O D. synthesize fatty acid
Answer:
[tex]\boxed {\boxed {\sf A. \ Synthesize \ proteins}}[/tex]
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: protein synthesis.
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.

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.

Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of Multiple Choice the nervous system, brain, and eyes. the endocrine and integumentary systems. the circulatory and respiratory systems. the muscles and bones.
Answer:
The correct answer is: the nervous system, brain, and eyes.
Explanation:
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are long-chain polyunsaturated fatty acids that have great nutritional value, as they are omega-6 and omega-3 fatty acids, respectively, meaning they are essential fats that cannot be produced by the body and, therefore, need to be part of the diet.
The consumption of ARA and DHA has been directly linked to the development of the brain and the retina, and the inclusion of these fatty acids in the nutrition of infants has been proven to be extremely beneficial to their growth.
Besides their functions in the development of the nervous system and the eyes, ARA and DHA play a role in maintaining a healthy immune system and preventing cardiovascular conditions.
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of the nervous system, brain, and eyes.
Arachidonic acid (ARA) and docosahexaenoic acid (DHA) represent two long-chain polyunsaturated fatty acids.In mammals, these polyunsaturated fatty acids (ARA and DHA) are fundamental during the development of the nervous system, and they are found in milk.It is for that reason that in some countries DHA and ARA nutrients are added to the milk formulas used to feed babies.In conclusion, arachidonic acid (ARA) and docosahexaenoic acid (DHA) are two long-chain fatty acids necessary for the development of the nervous system, brain, and eyes.

In order to determine the rate of photosynthesis (the conversion by plants of carbon dioxide and water into glucose and oxygen), the oxygen gas emitted by an aquatic plant is collected over water at a temperature of 293 K and a total pressure of 754.8 mmHg. Over a specific time-period, a total of 1.31 L of gas is collected. The partial pressure of water at 293 K is 17.55 mmHg. What mass of oxygen gas (in grams) forms
Answer:
1.6896 grams
Explanation:
Given that:
Total pressure = The pressure of [tex]O_2[/tex] + partial pressure of [tex]H_2O[/tex]
∴
The pressure of [tex]O_2[/tex] = Total pressure - partial pressure of [tex]H_2O[/tex]
= (754.8 - 17.55) mmHg
= 737.25 mmHg
At standard conditions:
1 mmHg = 0.00131579 atm
∴
737.25 mmHg will be: (737.25*0.00131579) atm = 0.970065928 atm
P ≅ 0.97 atm
The temperature (T) = 293 K
Volume (V) = 1.31 L
Using ideal gas equation
PV = nRT
0.97 × 1.31 = n × 0.0821 × 293
[tex]n = \dfrac{0.97 \times 1.31}{0.0821 \times 293}[/tex]
n = 0.0528
mass of oxygen [tex]O_2[/tex] = no. of moles * molar mass
= 0.0528 * 32
= 1.6896 grams

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").
