In this case, we have a dihybrid cross that is to say we are working with two alleles, the parental phenotype is round green (RrYy) and wrinkled green (rrYy). To obtain de genotypic ratios we must do the cross in a punnet square as follows.
We have the following genotypes and phenotypes
Round green, RrYY:2
Round green, RrYy:4
Round yellow, Rryy:2
Wrinkle green, rrYY:2
Wrinkle green, rrYy:4
Wrinkle yellow, rryy:2
Now the genotypic ratios of genotypes RrYy and rrYy are 4:16 (Option C 4/16), this is four of the 16 possible gametes will have RrYy combination and four of the 16 possible genotypes will have rrYy combination.
Now the phenotypic ratios are not considered in the options bus the logic is similar it would be 6:16, that is to say, six of the 16 possible offspring will have Round green phenotype, and 6 of the 16 will have Wrinkle green phenotype.

Answers
Answer:
During intense exercise:
lung capacity increases
vital capacity increases
respiratory capacity increases
functional residual capacity increases
tidal volume increases
the inspiratory and expiratory reserve volumes decrease as does the residual volume.
Explanation:
Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.
If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.
Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.
It is important to clarify that all the above processes are accompanied by an increase in the size of the chest cage

Which organism fix nitrogen in the soil ?
Answers
Answer:
Diazotrophs
Explanation:
The nitrogen-fixing bacteria and other micro organisms that fix nitrogen are collectively called 'Diazotrophs'. There are many strains of these bacteria in soil, which perform this function. They are important agents in the 'Nitrogen Cycle'.
There are two main groups of organisms that fix nitrogen in the soil: diazotrophs and cyanobacteria.
What are these organisms?Diazotrophics are bacteria that can convert atmospheric nitrogen into ammonia, which is a form of nitrogen that plants can use. Some examples of diazotrophs include Rhizobium, which is found in the root nodules of legumes, and Azotobacter, which is a free-living bacterium.
Cyanobacteria are photosynthetic bacteria that can also fix nitrogen. They are found in aquatic and terrestrial environments, and they can play an important role in the nitrogen cycle.

Did you lose or gain atoms in photosynthesis equation?
Answers
Photosynthesis is the process through which plants and other living things transform solar light energy into chemical energy (glucose).
A reduction-oxidation (redox) reaction, photosynthesis includes the exchange of electrons between different chemical entities. During the process, water is oxidized (i.e., loses electrons) to generate molecular oxygen, and carbon dioxide is reduced (i.e., gets electrons) to form glucose. It is an endergonic process because a chemical change cannot occur without the input of energy from the environment. In chloroplasts, the intricate process of photosynthesis occurs (i.e., membrane-bound organelles in plant and algal cells). Water and carbon dioxide are used in a sequence of processes that produce glucose and oxygen as a byproduct under the influence of sunlight. The basic formula for the overall balanced equation of photosynthesis is 6 \(CO_{2}\) + 6 \(H_{2} O\) \(C_{6} H_{12} O_{6}\) + 6 \(O_{2}\).In other words, in the presence of sunshine, the reaction between six molecules of carbon dioxide and six molecules of water results in the creation of one molecule of glucose.

Describe the role of GA in a-amylase production and in germination. Provide evidence for your claim
Answers
Gibberellic acid (GA) plays a crucial role in a-amylase production and germination. GA stimulates the synthesis and release of a-amylase enzymes, which hydrolyze starch into sugars during germination. Experimental studies have demonstrated that the application of GA accelerates a-amylase production and enhances germination in various plant species
In terms of a-amylase production, GA stimulates the synthesis and release of this enzyme. a-amylase is responsible for breaking down starch into simpler sugars, which are then utilized by the plant for growth and development.
Studies have shown that applying GA to plant tissues or seeds results in an increased production of a-amylase, facilitating the conversion of stored starch into energy-rich sugars.
Regarding germination, GA is involved in breaking seed dormancy and promoting the growth of the embryonic plant.
It stimulates the production of hydrolytic enzymes like a-amylase, which enable the hydrolysis of starch reserves in the endosperm, providing the energy needed for germination and seedling establishment.
Additionally, GA helps in cell elongation and division, promoting the growth of the embryo and the emergence of the radicle.
Evidence for GA's role in both processes includes studies where the exogenous application of GA to seeds or plant tissues has been shown to enhance a-amylase production and promote germination.
Conversely, inhibiting GA synthesis or action results in reduced a-amylase activity and impaired germination. These findings support the critical involvement of GA in both a-amylase production and germination processes in plants.

In saltwater, the water that surrounds a fish has a higher concentration of dissolved salts than is found in the fish's body cells. Which two methods allow the fish to maintain water balance? A. Pumping out salt through the gills B. Absorbing water into the body by osmosis C. Releasing only a little water in urine D. Taking in salts via food
Answers
The two methods that allow fish to maintain water balance in saltwater are pumping out salt through the gills and absorbing water into the body by osmosis.
In saltwater, the concentration of dissolved salts is higher in the surrounding water than in the fish's body cells. To maintain water balance, fish have developed two main methods:
1. Pumping out salt through the gills: Fish possess specialized cells in their gills that actively pump out excess salts from their bodies. This process helps maintain a lower salt concentration within the fish's body, preventing dehydration and maintaining water balance.
2. Absorbing water into the body by osmosis: Osmosis is the movement of water from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane. Fish have a protective layer of skin that allows water to be absorbed into their bodies while preventing the entry of excessive salts.
By absorbing water through their skin, fish replenish the water lost to the surrounding saltwater, helping to maintain their internal water balance.
These two mechanisms work together to enable fish to survive in saltwater environments. By actively pumping out salts and absorbing water, fish can regulate their internal salt concentration and prevent dehydration, ensuring their overall water balance is maintained.

Answers
The most recent common ancestor of Archaea, Bacteria, and Eukarya probably had none of the above characteristics.
It is believed that this ancestral organism was a simple, single-celled organism with a primitive cell membrane and a simple cell structure. It is thought that this ancestor lacked a nucleus, a membrane-enclosed intracellular compartment, and an enzyme to replicate DNA, and was capable of basic metabolic processes such as obtaining energy from the environment and producing new cellular material. Over time, this ancestral organism evolved and gave rise to the three domains of life we know today: Archaea, Bacteria, and Eukarya. These domains each have their own distinct characteristics and have evolved to occupy different ecological niches, but all can be traced back to this single common ancestor.
