Hello, people of planet earth, I need help with a question for my friend Steve in science class, here on planet Neptune it is pretty hard can you help me, please ?

Describe conjugation between two paramecium.

put it in simplest form because Steve is a bit of an idiot.

Answers

Answer 1
The paramecium has two nuclei, a big and small one. The big one operates as the director of the cell's activities, rather like a little brain. The smaller one is used for reproduction. The paramecium splits in half (fission) just as the ameba does. First the smaller nucleus splits in half and each half goes to either end of the paramecium. Then the bigger nucleus splits and the whole paramecium splits. Occasionally two paramecium exchange material and form a new paramecium. This is called conjugation. 

Conjugation in Paramecia occurs in the following way: 

a). The formation of ciliary contacts. 
b). Local loss of cilia and formation of narrow contacts between anterioventral somatic cell membranes 
c). Formation of small cytoplasmic bridges (which allow for the exchange of molecular components only). 
d). Their enlargement enables the cells to exchange micronuclei. 

Bacteria exchange plasmid material and the Paramecia exchange micronuclei.

Good luck to Steve! How is it in Neptune? XD

Which cell letter from the graphic organizer matches the fungus structure that releases digestive enzymes and absorbs digested organic material?
A. A
B. C
C. D
D. E

Answers

Answer: B hypha and D rhizoids

Explanation:

most of the fungi are saprotroph. They secretes digestive enzymes from hypha (B) of the mycelium on the dead and decaying matter. Digestive enzymes digest complex organic materials into simpler and soluble form in the external medium. With the help of root like structure called rhizoids (D) absorb nutrients from external medium into their body.

Final answer:

The fungal structure that releases enzymes and absorbs nutrients is the mycelium, made of hyphae; however, without the graphic organizer, an exact letter match can't be provided.

Explanation:

The fungus structure that releases digestive enzymes and absorbs digested organic material is known as the mycelium, composed of hyphae. These hyphae are specially adapted to maximize their surface area to volume ratio, ensuring efficient nutrient absorption following the extracellular digestion that occurs when the fungus releases hydrolytic enzymes into the environment.

The vocal cords vibrate to produce sound. This sound making process is known as

Answers

Larynx and Trachea *I'm not sure but I hope it helps*

The process of sound production by the vibration of vocal cords is called phonation, which is influenced by the tension and airflow through the cords. This is modified by articulators for speech.

Humans create sounds by exhaling air from the lungs which then passes through the larynx, where the vocal cords are located. The voice is produced by the vibration of these vocal folds when they come together, leaving a narrow slit for the air to pass through under pressure. The pitch of the sound can be altered by changing the tension on the vocal cords, while loudness depends on the airflow from the lungs influencing the amplitude of the sound waves.

Vocabulary such as voiced and voiceless phonation refers to whether the vocal folds are vibrating during the production of a sound. These vibrations, along with the movements of articulators like the tongue, lips, and jaw, modify the sound to produce distinct speech elements like vowels and consonants.

Give an example of how you could determine whether or not a trait was displaying incomplete dominance. What would you do? What would your results have to be for the trait to be incomplete dominant?

Answers

An example of incomplete dominance is: A snapdragon flower that is pink as a result of cross-pollination between a red flower and a white flower when neither the white or the red alleles are dominant.

Answer:

If one has to find that whether a trait is showing incomplete dominance, then post-mating the two species should produce an offspring that will demonstrate an intermediate character of the two parents. For example, in snapdragon flower, when red-colored flowers were crossed with the white one, the F1 generation exhibited all pink flowers, that is, a trait, which is an intermediate between the two.  

The outcomes, which shows that whether a trait is incomplete dominant are that the F1 generation should exhibit an intermediate character of the two parents, and the F2 progeny should exhibit a phenotypic and genotypic ratio of 1:2:1.  

A nurse is providing disaster care in an event that is known to involve gamma radiation. when admitting victims of the disaster, what should the nurse do to best reduce victims' risks of injury?

Answers

For the answer to the question above, the nurse must remove victim's clothing and have them wash thoroughly.

The nurse should've victim's shower and change clothes and irrigate or wash open wounds with soap and water. Cleansing the skin helps to reduce the transition from external to the internal radiologic contamination. Infectious micro-organisms are not involved, so chlorhexidine is of no particular benefit. Applying PPE over contaminated clothing could make the risk of injury worst. Good ventilation is very important, also the removal of contaminants is the priority because of the increased risk of injury.

The right answer is Remove victims' clothing and have them wash thoroughly.

The doctrine of medical management of accidental contaminations with the presence of injured, burned or shocked victims (blast effect ), is clearly established and internationally recognized. It comes down to a golden rule: the medical emergency takes precedence over the radiological emergency. The management of accidental contaminations is essentially operational with a reflex phase where the emergency medical teams must deploy at the accident site an advanced medical post including chains of decontamination, undressing, and showers. The objective is to perform a medical sorting of the victims and to eliminate the radioactivity deposited on the clothes and the skin.

This is a trait that is a blend of the dominant and recessive gene: tall X short medium height

Answers

Answer:

It would be incomplete dominance

Explanation:

Please thank me! :)

The trait of medium height in the offspring of a tall and short parent is an example of incomplete dominance.

What is incomplete dominance?

Incomplete dominance is a type of inheritance where the heterozygous genotype expresses a phenotype that is intermediate between the two homozygous genotypes. In this case, neither the dominant nor the recessive trait is fully expressed, resulting in an intermediate phenotype. It occurs because the alleles for a particular trait are neither completely dominant nor completely recessive, and as a result, a blending of traits occurs in the offspring.

The trait of medium height in the offspring of a tall and short parent is an example of incomplete dominance, where neither the dominant nor the recessive trait is fully expressed, resulting in an intermediate phenotype.

What is the correct order for the reactions of the calvin cycle?

Answers

The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. These reactions use chemical energy from NADPH and ATP that were produced in the lightreactions.

The correct order for the reactions of the calvin cycle is  Carboxylation → reduction → Regeneration.

What is calvin cycle?

A series of chemical reactions known as the Calvin cycle, light-independent reactions, biosynthetic phase, dark reactions, or photosynthetic carbon reduction cycle of photosynthesis occurs during the phase of photosynthesis in which carbon dioxide and hydrogen-carrier compounds are converted into glucose.

Carbon dioxide is fixed during the first stage of the Calvin cycle, which is also the stage in which the light-independent processes begin. ATP and NADPH are responsible for the reduction of 3PGA to G3P during the second stage of the C3 cycle. After then, ATP and NADPH undergo a reaction that produces ATP and NADP+. RuBP is regenerated during the last stage of the process.

In the meselson-stahl experiment, cells were grown for one generation in growth medium containing a relatively heavy nitrogen isotope, then transferred to new medium containing a lighter nitrogen isotope. after one round of dna replication, what was true of the dna in the cells?

Answers

Out of the following give choices;

a. All DNA strands contained only the heavy nitrogen isotope.

b. Half of the DNA strands contained only the light nitrogen isotope.

c. All DNA strands contained both heavy and light nitrogen isotopes.

d. All DNA strands contained only the lighter nitrogen isotope.

The answer is b. Meselson–Stahl experiment demonstrated the semi-conservative model of DNA replication. When DNA is replicated, one strand of the new double helix strand is the parent's strand while the other is the newly synthesized one. This made the semiconservative model stand out over the other two, dispersive and conservative models.






After one round of DNA replication in the lighter nitrogen medium, the DNA in the cells was hybrid DNA. This means each DNA molecule consisted of one strand of the original heavy (¹⁵N) DNA and one strand of newly synthesized light (¹⁴N) DNA.

The Meselson-Stahl experiment was designed to determine the method of DNA replication.

In this experiment, cells of E. coli were grown initially in a medium containing a heavy nitrogen isotope (¹⁵N) and then transferred to a medium containing a lighter nitrogen isotope (¹⁴N). The DNA was extracted at various times and analyzed by density gradient centrifugation. After one round of DNA replication in the lighter nitrogen medium, the characteristics of the DNA provided critical insights into the mechanism of DNA replication.

Key Steps and Findings:

1. Initial Growth in Heavy Nitrogen (¹⁵N) Medium:

Cells incorporate ¹⁵N into their DNA, resulting in "heavy" DNA.When centrifuged, this DNA forms a band at a specific, lower position in the density gradient due to its higher density.

2. Transfer to Light Nitrogen (¹⁴N) Medium:

Cells are transferred to a medium containing ¹⁴N and allowed to replicate.

3. One Round of DNA Replication:

DNA is extracted from cells after one round of replication in the ¹⁴N medium.

Observations After One Round of Replication:

Intermediate Density:

The DNA forms a single band at an intermediate position in the density gradient, between the positions of the heavy (¹⁵N) and light (¹⁴N) DNA.This intermediate band indicates that each DNA molecule consists of one original strand containing ¹⁵N and one newly synthesized strand containing ¹⁴N.

Interpretation:

The presence of DNA with intermediate density supports the semiconservative model of DNA replication.In semiconservative replication, each daughter DNA molecule consists of one original (parental) strand and one newly synthesized strand.The observed intermediate density band indicates that each DNA molecule after one replication round is a hybrid, containing one strand with ¹⁵N and one strand with ¹⁴N.

Conclusion:

After one round of DNA replication in the lighter nitrogen medium, the DNA in the cells was hybrid DNA. This means each DNA molecule consisted of one strand of the original heavy (¹⁵N) DNA and one strand of newly synthesized light (¹⁴N) DNA. This crucial finding supported the semiconservative model of DNA replication, where each new DNA molecule retains one parental strand and includes one newly synthesized strand.
