How can I use the analogy of building blocks to explain how genes relate to the diversity of life?

Answers

Answer:

-Building blocks are the fundamentals to an overall result, in this case being the characteristics of a human being.

-This is related to genes as the variety of building blocks can make a completely different "outcome" just as a different gene can trigger a different characteristic.

- Without different building blocks, all outcomes will be the same, just as humans. So a variety of "building blocks" are needed for diversity.

A running back is running down the field and two people on the opposing team run towards him. One person is running east with a force of 250 N. The other person is running west with 250 N of force . They all collide at the same time. Show the forces affecting the running back.

Are the forces balanced or unbalanced?

Net force = ?

Answers

Given our understanding of the laws of physics, we can confirm that the Net force affecting the running back (ignoring gravity and its complementary force) is that of 500N and balanced.

In physics, we can say that the net forces being applied to an object are balanced when the forces are

Equal in sizeApplied in opposite directionsApplied at the same time.

The question states that the running back collides with two members of the opposing team at the same time. This, coupled with the fact that the opposing team members are described to arrive on exactly opposite sides, we can say that the forces being applied to the running back are indeed balanced.

Furthermore, since the forces are 250N in size each, we can confirm that the net force applied to the running back is 500N. To this, we would normally add the force of gravity, however, in order to do this, we would need the weight of the running back, that is, data that is not provided.

Which of the following characteristics do homologous chromosomes exhibit?.

Answers

Homologous chromosomes carry alleles of the same traits and therefore, carry the genetic information for the same trait.

Homologous chromosomes are a pair of chromosomes with the same gene sequence but of different origins - one paternal and the other maternal.

Thus, homologous chromosomes carry the same traits, although could be of different forms. For example, one of the chromosomes might carry a gene for tallness while the other might carry a gene for shortness even though both tallness/shortness represent a gene for height.

12)At a point during a cell's development, it begins to differentiate. How does differentiation occur? *

The number of chromosomes in the cell is reduced by half; this action triggers the specialization of the cell.

why would you not use green light and white light if you wanted to determine the dependence of specific color wavelengths on the rate of photosynthesis?

Answers

Given our understanding of the situation, we can confirm that the use of green or white light would not be ideal for the experiment at hand because it will not yield any useful information.

In this experiment, we wish to determine the dependence of specific color wavelengths on the rate of photosynthesis. The use of white light for this experiment will defeat the purpose, given that white is the naturally occurring color of light and the available data on this is vast.

Furthermore, we would not use green colored light because it will not be effective. The effectiveness of the color of light that we decide to use will be based on the absorption rate of the light at a cellular level. Green light is known to not be well absorbed by the chlorophyll of plants and therefore will not be useful.

POINTS AND BRAINLIEST!Surface Water Lab ReportIntroductionUsing models is very important in science. In this lab, you will design a model that will help you investigate the relationship between land surfaces and water on Earth. Problem: How can we use the relationships between land surfaces and water to understand conservation of resources and pollution?Hypothesis: After completing steps 1 through 5 in your procedures, predict the number and locations of watersheds that will form in your watershed model. For example:Based on the positions of landscape features in my watershed model, I predict there will be ________ number of watersheds located at these locations in my model: __________________________________.Materials: If you would like to create your watershed model by hand, you will need the materials listed. Note: There are alternative procedures that do not require these materials.one sheet of plain white paperseveral sheets of old newspaper, or wax paper if availableone water-based marker (Note: do not use permanent marker)one spray bottle containing water (place on mist setting)digital camera, if availableProcedures:Place several sheets of newspaper or wax paper over a large flat surface, such as a kitchen counter. Use at least five sheets of paper so that you can protect your work area. Crumple the sheet of white paper into a loose wad.Uncrumple the sheet of paper so you can lay it on your work surface. The paper should not be flat but should be wrinkled and puffed up from the crumpling.Imagine the paper as a miniaturized version of mountains, hills, valleys, and other landscape features. If your paper is so flat that you can't imagine these features, you should recrumple it.Use the marker to color the major folds or ridges in the paper, as well as some of the minor folds or ridges. Do not allow the marker to color any other part of the paper.Place the paper on top of the newspaper on the counter, and then lightly mist the piece of paper with the spray bottle. Don't spray too heavily: Three to seven squirts will probably do the job.Stop misting as soon as you see some of the colored water starting to collect in some of the valleys. Watch for a few moments as stream patterns develop over the paper.If you have access to a digital camera, take a photograph of your work and include it in your Data and Observations.Record your observations of each watershed that forms in Table 1.
