What type of cross did Mendel use to determine the probability of offspring when investigating two characteristics at a time

Answers

Answer 1

Answer:

When the offspring in Mendel's experiment were self-crossed, the F2 offspring exhibited the dominant trait or the recessive trait in a 3:1 ratio, confirming that the recessive trait had been transmitted faithfully from the original P0 parent. Reciprocal crosses generated identical F1 and F2 offspring ratios.

Human powered generators are the best source for the rescue team. We cannot always depend on the sun. What if the sun is not out that day? What if it's a rainy day? What if the sun is what's causing the rescue team to come out? Human powered generators are sometimes untrustworthy, but at the same time we know that at least it's a step away. We don't have to wait all-day for the sun to help out. Of course, the energy from the sun is always going to be there and won't cause anybody hurt, harm, or danger, but at the same time we can always convert to human powered generators and they'll work just as perfect.

Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles. Some organelles are found only in some cell types.

Answers

Answer:

This question is incomplete

Explanation:

However, as described in the question. each cell organelle has specialized function that assists the cell carry-out it's own function as a whole. Cell organelles include cell membrane, smooth and rough endoplasmic reticulum, vacuole, golgi complex, lysosomes, nucleus, mitochondria, chloroplasts among others.

Of these cell organelles, only three were mentioned in the question

Nucleus: This houses the chromosome which stores genetic material. This organelle is found in plant and animal eukaryotic cells. Indeed, eukaryotic organisms are sometimes described as organisms that have well defined nucleus.

Mitochondria: They are found in most plant and animal eukaryotic cells. They are usually referred to as the power house of the cell as they provide energy-rich chemical compounds (called ATP) for the cell's activities.

Chloroplasts: These are cellular structures/organelles that are found only in  green plants - they are cellular machinery for photosynthesis in plants. They also contain the green pigment called chlorophyll which is responsible for the green colour of green plants.

The type of the cell in which the organelles mentioned in the question are listed above.

How does starting the y-axis at 300 affect the graph? Remember that no matter what number you start labeling an axis at, you have to go up by the same amount for each subsequent tick mark!

Answers

Not sure if this applies to biology, but I’m using more statistics for this.

Basically, when you change the y-axis to 300, you are able to exaggerate the patterns on the graph. From afar, or starting the y-axis at 0, a person cannot easily identify the increases and decreases of CO2. However, with a y-axis at 300, you see these changes much more easily, so you can make accurate inferences and conclusions regarding the graph.
