How would a prolonged period of photorespiration affect a plant?
Solution:
Photorespiration consumes ATP and NADPH (high-energy molecules). In fact, Photorespiration wastes energy and steals carbon. These molecules are necessary for photosynthesis to synthesize carbohydrates. Therefore, a prolonged period of photorespiration affects the plants because the photorespiration prevents plants from using their ATP and NADPH to synthesize carbohydrates. Remember that carbohydrates are necessary for plants for their own support and their progeny (seeds). Therefore, therefore, photorespiration strongly reduces the photosynthetic capacity of plants, also affecting the normal functions of subcellular organelles.
how you can determine if you are looking at a Zygomycetes, Ascomycetes, or Basidiomycetes. What structures would you be looking for? Are they Sexual? Asexual?
You are looking at fungi and the structure Zygomycetes, Ascomycetes, or Basidiomycetes are used for sexual reproduction .
Zygomycota generally harvest spores inside sporangia. Ascomycota harvest spores inside asci while Basidiomycota produce spores on a platform called a basidium. The spores produced by Basidiomycota are generally made using sexual reproduction.
Zygomycota is having non-septate hyphae with numerous nuclei. Their hyphae blends during sexual reproduction to yield a zygospore in a zygosporangium. Ascomycota (sac fungi) form spores in sacs called asci during sexual reproduction. sexual reproduction is their common phenomenon of reproduction.

The process in the image is transcription. This is mRNA synthesis and occurs in the nucleus. mRNA copies a segment of DNA and carries this information to the cytoplasm to synthesize new proteins.
What is transcription?
Transcription is the mRNA synthesis process. It occurs in the nucleus and is the previous stage before protein synthesis (translation).
During transcription, fragments of DNA molecules are used to copy the desired sequence that carries the necessary information to grow the new proteins.
In the nucleus, the DNI molecule uncoils and forms the transcription bubble, separating the two strands.
At this point, two fragments of DNA can be identified, the coding strand and the template strand.
The coding strand –non-template strand- goes in direction 5' to 3',The complementary strand -template strand- grows in direction 3' to 5'.The template strand acts as a mold for mRNA growth. This is the chain that is complemented by the mRNA.
On the other hand, the coding strand (non-template) carries the same nucleotidic sequence as the new mRNA. The only difference is that instead of Uracyls (which are only present in RNA molecules), it has Thymines (which are only found in DNA).
RNA polymerase is in charge of reading the original DNI template strand and for mRNA synthesis.
mRNA molecule grows complementing DNA base sequences. This is,
DNA mRNA
adenine ⇔ uracil
guanine ⇔ cytosine
thymine ⇔ adenine
cytosine ⇔ guanine
Once mRNA synthesis is over, the molecule leaves the nucleus to start the translation process in the cytoplasm.
Note: I could not find the image, but the labels suggest this is a transcription process.
The process is Transcription. It produces mRNA, the molecule that carries genetic information from the nucleus to the cytoplasm to build new proteins.

What disease does this parasite cause? What is its invertebrate host (vector/ intermediary host)
Flagellate parasites typically tend to cause a disease known as Chagas' disease. It usually presents itself with flu-like symptoms. It is treatable. However, if left untreated it can lead to heart failure.
Oftentimes, the invertebrate host for this parasite is the triatomine inspect the parasite takes over. These insects then spread the parasite to the vertebrate host (the human).
Which of these organisms can move on its own?oak treeanteaterdolphinall of the above
Of the organisms provided, we have two animals and a plant, so if we see it as locomotion capacity only anteater and dolphin would be correct. Now if we are more specific and just took movement as the capacity to move even small parts, a plant can also be considered, we must remember that even when plants are sessile organisms, they grow and seek light, thus they can move although we are not capable of seeing it.
A barracuda stalking a school of parrot fish is an example of(A) altruistic behavior.(B) cognitive behavior.(C) competitive behavior.(D) foraging behavior. I think it’s answer (C) but I just want to make sure!
Here we have a barracuda a predator fish and parrotfish as prey, now if we analyze each available option we can see that option A is not correct as there is no benefit for the parrotfish, option B is not correct either as predation is an instinctive behavior. Now with option C, we must be careful as in the first place predation leads to competition, however, in this case, there is no mention of other predator fish be another barracuda, or other species meanwhile option D, foraging behavior implies the consumption of food, seeking, selection and manipulation of it so in this particular case, stalking a school of fish falls under this category, therefore option D is the correct answer.
In a family the mother has color blindness and the father has normal vision. Their child has Klinefelter syndrome and normal vision. How is this explained and what gametes did this child give? We assume that the above parents had a child with Klinefelter syndrome and color blindness. How can this happen?
The child can have normal vision if she inherites a healthy X chromosome from the father, for this to happen, the child must be a woman.
If the child is a man, he can have normal vision as he has Klinefelter syndrome, which consist on having an extra X chromosome from his father, giving him normal vision even though the mother can only give him X chromosomes with color blindness. Moreover, this can happen as colour blindness is a recesive trait.

Answer: Myelogram
Explanation:
Congenital deafness in humans is due to the homozygous condition of either of the recessive genes d or e, or both of these genes. Both dominant D and E are necessary for normal hearing. Gene D/d affects the middle ear, while gene E/e affects the inner ear as indicated by E It does not matter how good the normal inner ear is: if there is something wrong in the middle ear, the individual is unable to hear. The same applies for the other gene. Give the phenotypic results of the following crosses: c) ddEE x DD eed) Dd EE x Dd ee
To make the punnet's square first we need to combine the allele to obtain the gametes possibilities. Then we make the cross to obtain the possible offspring
1 DdEE x 2 Ddee
Gametes:
1: DE / DE / dE / dE
2: De / De / de / de
Now we obtain the phenotypic ratios:
Given that dd/ee = deafness then:
4/16 of the offspring will have congenital deafness because of the genotype: ddEe specifically because of the dd alleles.
Which of the following is not a form of energy
Answer:
Magnetic.
Explanation:
Electric energy is the energy caused by the movement of the electric charges. The moving electric charges form the kinetic energy, thus electrical is the from of energy.
Thermal energy is the energy which usually comes from the heat.This heat is generated by the movement of tiny particles within an object. Thus, thermal energy is the form of energy.
Nuclear energy is the energy which comes from the splitting atoms in a reactor to heat water into steam and generate electricity. Thus, nuclear energy is the form of energy.
The magnets cannot be used to generate energy, as it is kind of a force which attracts a body from the another body, therefore the magnetic is not the form of energy.

Is the enzyme for lactose being made with the repressor not in place?
The lactase is an enzyme in the small intestine that breaks lactose into simpler sugar forms (galactose and glucose) that can be absorbed to generate energy. That sugar is important for gene regulation because it is linked to the Lac operon, the repressor for this structure prevents the DNA transcription, if the repressor is not in place the operon works and the enzyme is produced, being the lac repressor innately active in the absent of lactose.
Given what we now know about atmospheric and oceanic transport, are the concepts of local, regional, and global pollution still useful?
The concepts of local, regional, and global pollution are useful both in consideration of atmospheric and oceanic transport because there are pollutant substances that spread in a local way while others may encompass extended regions.
What are local, regional, and global pollution?Local pollution refers to all procedures that might contaminate a limited area such as a city or a lake, which may be avoided by recycling waste materials or avoiding the spread of residual water.
Conversely, regional pollution and global pollution affect longer-extended areas and these situations should be maintained by government policies in order to avoid harmful and or dangerous concerns (e.g. the scope of radioactive material).
Therefore, with this data, we can see that local, regional, and global pollution are useful concepts to develop measures to control different types of contaminants and pollutant substances that may affect the quality of life of people.

What is the advantage to the virus if they have an envelope?
The advantage is related to the protection of the genome. An envelope is responsible for protecting the genome while the virus travels between host cells. The envelope also plays a role in the infection, because it has glycoproteins in its surface to identify receptor sites on the host's cells. After the identification, the virus binds itself on the host's membrane.

Taking into account that in the presented model, the original double-strand DNA chain is composed of gumdrops, and the newly synthesized strands will be composed of marshmallows (in order to be more visual), we will have different percentages of the original DNA strand and the new one depending on the model we follow:
-Conservative model: we will have two double-strand DNA molecules from the original one. Say DNA molecule A stays with no changes (because it is just used as a mold), then it will be composed only by gumdrops (100%); and DNA molecule B will be totally new, composed then only with marshmallows (100%) because it is synthesized from scratch from the other one.
-Dispersive model: we also will have two double-strand DNA molecules from the original one but unlike the previous case, the original DNA molecule is fragmented into little pieces, and each daughter molecule will have some of these pieces mixed in their two strands. When calculating the percentages, we can say both DNA molecules, A and B will have 50% gumdrops and 50% marshmallows approximately and theoretically.
-Semiconservative model: In this case, as the original DNA model transfers one strand of its structure to each daughter DNA molecule, we can say that both molecules, A and B will also have 50% gumdrops and 50% marshmallows, just like in the previous case, but with the difference that all the gumdrops will be in just one strand and all the marshmallows in the other one of each.
