The F2 generation phenotypes resulting from the monohybrid cross of purebreds display a ratio of _____.

Answers

Answer 1

Answer: In the sentence "The F2 generation phenotypes resulting from the monohybrid cross of purebreds display a ratio of _____" the word that correctly completes the sentence is 3:1. In the monohybrid cross of purebreds, F1 generation will consist of heterozygotes with dominant phenotype. When F1 generation cross, the F2 generation phenotypes will be as following: 3 dominant phenotypes (1 dominant homozygote and 2 heterozygotes) and 1 recessive phenotype (1 recessive homozygote).

Answer 2

Answer:

Answer:3:1

Imagine that you work at the medical examiner's office for a major metropolitan city. As Chief Medical officer, you investigate suspicious deaths and provide toxicology services for the county. Unfortunately, it's been a busy week. In the past five days, seven people have died, all with similar symptoms. It is your job to examine the data and determine the cause of death for these victims. The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning, the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby hospital, where she was pronounced dead. That same day, paramedics found the second victim unconscious on his kitchen floor after what they thought was an apparent heart attack. Sadly, the victim's brother and fiancée also collapsed later that night while the family gathered to morn his passing. Both had taken Tylenol to help them cope with their loss shortly before collapsing; neither survived.In the next four days, four other similar deaths were reported, all in the same neighborhood and all with similar symptoms. Are these seven deaths related? What is causing these people to die? It is your job to answer these questions before more deaths are reported.Symptoms exhibited by most patients: (i)-Dizziness(ii)-Confusion(iii)-Headache(iv)-Shortness of breath/rapid breathing(v)-Vomiting(vi)-Most deaths were very rapid, occurring within a few hours of symptoms.Explain whether or not you think these 7 deaths are related, and what questions you would ask the families of the victims.

What is a stack of thylakoids called?

Answers

Answer:

Grana

Explanation:

The thylakoids are arranged in tight stacks called grana (singular granum).

Answer:

A stack of thylakoids is called a grana.

Explanation:

Thylakoids are flattened, membrane-bound structures found within the chloroplasts of plant cells and some photosynthetic bacteria. They contain the pigments and other molecules necessary for the process of photosynthesis.

A grana is formed when multiple thylakoids stack on top of each other. These stacks are connected by intergranal lamellae, which are extensions of thylakoid membranes that link adjacent grana together.

The arrangement of thylakoids into grana is important for the efficiency of photosynthesis. It increases the surface area available for light absorption and provides a structured organization for the flow of electrons and energy during the light-dependent reactions of photosynthesis.

In summary, a stack of thylakoids is called a grana. This organization of thylakoids plays a vital role in the process of photosynthesis by providing an efficient structure for light absorption and electron transport.

An experiment is done on three tomato plants over a 50 day period to test the following hypothesis: If either fertilizer or compost is used on plants then a plant that gets fertilizer will affect the plant growth the most. The same amount of water and light were applied to each tomato plant. Pot A contained no fertilizer or compost, Pot B contained fertilizer and Pot C contained compost. Which is the independent variable? a. Time of experiment b. Amount of water c. Plant growth d. Amount of fertilizer

Answers

the correct answer is d. Amount of fertilizer. The independentvariable is the variable that is deliberately changed or manipulated in an experiment to see its effect on the dependent variable.

In this experiment, the independent variable is the amount of fertilizer or compost added to the tomato plants, as it is the variable being intentionally varied to test the hypothesis. Therefore, the correct answer is d. Amount of fertilizer. The dependent variable in this experiment is plantgrowth, which is the variable being measured to determine the effect of the independent variable. The other variables mentioned, time of experiment and amount of water, are likely held constant throughout the experiment as part of the experimental design, and therefore do not serve as independent variables.

in an aquatic ecosystem, the algae and phytoplankton are responsible for primary productivity. All BUT ONE factor usually influences the primary productivity of a marine ecosystem. That is a)water salinity b)light intensity c)water temperature d)available nutrients

Answers

Answer: Light intensity

Explanation:

The total amount of nutrient( organic material) which is left after respiration, in order to support the other levels of the food chain is known as the net primary productivity.

More than 90% of the producers are the pytoplanktons that performs the process of photosynthesis.

The intensity of light falling on the water surface affects the rate of primary productivity.
