Answer: The event that DOESN'T occur during bacterial conjugation is (Transfer of the DNA strands occurs in both directions)
Explanation:
Bacterial Conjugation can be defined as the type of sexual reproduction that can take place in bacteria in which genetic materials are being moved from a bacteria donor cell to a recipient through a DIRECT contact. The bacteria cells which act as donors contain DNA called the fertility factor ( F factor).
The detailed stages of conjugation which occurs in bacteria includes:
--> A direct contact is first established between the donor cell and the recipient cell through the use of a structure called the pilus. This structure is projects out from the donor cell.
--> the pilus shortens and a direct contact established between the two bacteria leads to formation of conjugation tube.
--> At the Origin of transfer site, an enzyme known as the HELICASE cleaves one strand of the F factor DNA. A strand is transferred to the recipient bacterial cell.
--> In the last step, the donor cell and the recipient cell, both contains single-stranded DNA of F - factor. Therefore, the recipient cell also contain a copy of F-factor and become a donor cell.
The option which says that transfer of DNA strands occurs in both directions is wrong because from the steps listed above, one strand of the F-factor DNA is transferred from a donor bacterial cell to a recipient, that is, unidirectional transfer of DNA and not in both directions.

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

how many grams of nitrogen -16 will br left from a 16g sample after 21.6 seconds if its half life is 7.2 seconds
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:
TTT GCC AGT
Explanation:
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%

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.

Answer:

Explanation:
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").
