A. below 7

On a pH scale, 7.0 is considered neutral, while values higher than 7.0 are basic, and values less than 7.0 are acidic.

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.

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.

Traits of sunflowers

Tall plant: dominant (T)

Short plant: recessive (t)

Yellow-colored flowers: dominant (Y)

Orange-colored flowers: recessive (y)

P1 (heterozygous for both traits)

Tt Yy

P2 (homozygous dominant for height, heterozygous for color)

TT Yy

After the breed, we would have the following offspring:

What this means is that those inside blue (TtYy; 4 individuals (25 % of the offspring) and green (TTYy; 4 individuals (25 % of the offspring)) circles have the respective genotype of their parents, in other words, they inherited their very phenotypical traits, while there're other percentages of the offspring which could have traits of their both parents in its phenotype.

Okay, if a cell's placed in an hypertonic media, this means a media with a higher concentration of solutes (like nutrients) than in the inside of the cell, what will happen with the cell is that it gets dehydrated due to the outtake of water by osmosis.

Earth needs to rotate and revolve both ways in order to maintain temperature.  If it didn't go one side will become too hot and one will become too colder.

Rotation is the movement  of Earth around its axis and revolution is the movement of the planet around the sun.

If Earth didn't rotate then the one side of the planet will face continuous heat and the sun whereas the other will not face the sun and in these conditions one side of Earth will become extremely hot and the one side will become extremely colder region.

Therefore in order to maintain the temperature and the environment conditions the need of Earth rotation is required continuously.

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.

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.

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.

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 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.

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.

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.

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.

The correct answer is the second one, classical conditioning. Pavlov worked with typical stymulus associated with either benefits or punishments. This conditioned dogs to different behaviours.

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.

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.

Asking whether protein synthesis is important to the process of muscle cell relaxing, the response will be option 3. Yes, protein synthesis is important because the ions exit the cell via mediated transport actively.

Protein synthesis is the activities through which cells make proteins. Protein synthesis is important purposely for the process of muscle relaxation so also muscle contraction. Considering muscle relaxing and contraction, particular ions are needed to be transported across the muscle cell membrane which can flow either from out to in or in to out.
