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%

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.

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

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.

Explanation:
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

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.
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").
