"it is a reductive process"

Explanation:

both oxidation and reduction take place in photosynthesis so we cannot classify it as just reductive.

in photosynthesis the water is oxidised while co2 is reduced. this basically transforms co2 into glucose and water into oxygen

hope this helps

Answer:

yes you are correct the answer would be "B"

Explanation:

The phylum of plants known as Lycophyta, Monilophyta, is distinguished by the absence of real leaves, dichotomous branching, and lobed sporangia.

These whisk ferns, class Psilotopsida, lack either leaves and stems, which were likely lost during reduction, whereas the majority of ferns grow huge leaves and branching roots. Its green stems, that branch dichotomously, perform photosynthesis. The adult sporophyte of Psilotum typically reaches a height of 30 cm but may do so even higher. Its stem is green & photosynthetic instead of having genuine leaves, and it is coated in stomates to facilitate gas exchange.The phylum of plants known as Lycophyta, Monilophyta, is distinguished by the absence of real leaves, dichotomous branching, and lobed sporangia. Psilotum whisk ferns are rooted by creeping rhizomes instead of having actual roots. There are numerous branches and paired enations on the stems, which resemble tiny leaves but lack vascular tissue. Above these enations are synangia, which are created when three sporangia fuse and release the spores.

Answer:

Stomata or lenticels have similar purposes.

Answer:

Percentage of offspring with straight hair: 75%

Percentage of offspring with curly hair: 25%

Genotypic ratio: 1:2:1

Explanation:

In a monohybrid cross between two parents heterozygous (carrying one dominant and one recessive allele) for straight hair, where straight hair is dominant (S) and curly hair is recessive (s), the genotypes of the parents can be represented as Ss.

To determine the percentage of their offspring with straight hair and curly hair, we can use Punnett square analysis.

The Punnett square for the monohybrid cross between the parents would look like this:

      S      s

S    SS     Ss

s    Ss     ss

From the Punnett square, we can see that there are four possible genotypes for the offspring: SS, Ss, Ss, and ss.

The genotypes SS and Ss correspond to individuals with straight hair, while ss corresponds to individuals with curly hair.

So, the percentage of their offspring with straight hair would be 75% (3 out of 4 possible genotypes), and the percentage with curly hair would be 25% (1 out of 4 possible genotypes).

The genotypic ratio for their offspring would be 1:2:1, meaning that for every four offspring, one would have the genotype SS (homozygous dominant for straight hair), two would have the genotype Ss (heterozygous for straight hair), and one would have the genotype ss (homozygous recessive for curly hair).

Based on the information provided, a good estimate of the carrying capacity, K, of wolves in the Northern range for the next decade would be within the range of 400 to 600.

Carrying capacity refers to the maximum population size that an ecosystem can sustainably support over a given period of time. In this scenario, biologists believe that the elk population has stabilized between 4,000 and 6,000, indicating that the ecosystem can support this range of elk numbers without significant fluctuations. Wolves are a natural predator of elk, and their population size is influenced by the availability of prey. Therefore, a reasonable estimate for the carrying capacity of wolves would be a proportionate range to that of the elk population, which in this case is 400 to 600. It's important to note that estimating carrying capacity involves various ecological factors and can be influenced by other variables, such as habitat quality and availability of resources.

Explanation:

the strength of magnet increase with increasing number of turns in the coil.

the strength of the electromagnet is directly proportional to the number of turns in the coil. if you double the number of turns, you double the strength of the electromagnet.

The number of wire coils on an electromagnet affects the strength, as the strength is directly proportional to the number of turns in the coil.

An electromagnet is a type of magnet where an electric current creates a magnetic field. The wire that makes up an electromagnet is typically twisted into a coil. A magnetic field is produced by a current flowing through the wire and is concentrated in the hole at the center of the coil.

As the coil's turns grow, the magnet's strength does as well. The coil's number of turns directly relates to the electromagnet's strength. The electromagnet's strength doubles when the number of rotations is doubled.

Therefore, since the strength is inversely related to the number of turns in the coil, the number of wire coils on an electromagnet affects its strength.
