All organisms have adaptations. The list below describes how different adaptations might affect different species. A bird species that develops a longer beak would be able to extract insects from holes that are deep within trees. A plant species that develops the ability to excrete salt through the leaves of the plant could survive in soils that have high concentrations of salt. A rodent species that develops the ability to hibernate, or remain inactive during the winter months, would be able to conserve energy when little food is available. Which of the following is true? Adaptations allow individual organisms to change their structures based on environmental conditions. The inherited characteristics of a species change over time based on the use or disuse of particular characteristics. Sudden environmental changes are always necessary for the development of new adaptations. Adaptations increase the probability of an organism surviving and reproducing in a specific environment.

Two chickens are bred and produce the following numbers of offspring. What are the most likely appearances of parents

Answers

The correct answer is - One parent has white feathers and one has red/white feathers.

The offspring, the chickens, have feathers that are only white, or feathers that are with both red and white color. There's not a single individual in the offspring that has only red feathers.

That leads to the conclusion that one of the parents had white feathers, while the other had red and white feathers, as those are the only two combinations in their offspring.

A parent that has only red feathers can be excluded (though not 100%) because there's not a single chick out of the 30 chicks with red feathers, and if there was a red feathered parent the chances are very high that at least one of them will be red feathered as well.

Answer: One parent has white feathers and one has red/white feathers.

b) metaphase)

c)anaphase

d) telophase

I need help!

Answers

Prophase: Replication of chromosomes and chromosome become visible x shapes.

Metaphase: Chromosomes align at the equator of the cell and spindle fibers attach to each sister chromatid.

Anaphase: Spindle fibers pull the sister chromatids away from each other to the opposite sides of the cell.

Telophase: New separate nuclear membranes form around the different sets of chromosomes and the chromosomes unwind, the spindle fibers start breaking down and and the cell begins to pinch together to separate into two new cells.

How are light microscopes different from electron microscopes?Electron microscopes can view the internal part of a cell, while light microscopes view the surface of a cell.
Electron microscopes' specimens can be stained for contrast, while light microscopes' specimens appear black and white
Electron microscopes are used for dissections, while compound light microscopes are not.
Electron microscopes use electron beams and electromagnetic lenses, while compound light microscopes use light and ocular and objective lenses.

Answers

Explanation:

D) Electron microscopes use electron beams and electromagnetic lenses, while compound light microscopes use light and ocular and objective lenses.

Microscopes are instruments used for viewing microscopic cellular structures, not visible with the human eye. With an arrangement of lenses, and manipulation of light or electrons, these magnify very small objects. Light microscopy uses light and multiple lenses, while electron microscopes use electrons. These create larger images of objects.

While light microscopes with a resolution power of 0.2 um can view objects at a magnification x1000, electron microscopes are capable of a much smaller resolution at 0.5 nm and magnification of x100,000.

The wavelengths of light in the visible part of the eletromagnetic spectrum (visible light is between 390 nm and 760 nm,) are manipulated in light microscopy. The visible light is passed through the biological sample where it bends, as it travels through multiple lenses. This is often usable on live organisms. Thus the observer can look at cells as they undergo division or locomotion. Resolution describes the shortest distance, where two objects are still visible as distinct bodies. With light microscopes, one may view objects between a millimeter (10-3 m) and a fraction of a micrometer at 0.2 thousands of a millimetre or 2 x 10-7 m.

Unlike light microscopy, electron microscopy involves the manipulation of electrons through the apparatus, under a vacuum. As the beams of electrons have shorter wavelengths than light particles, the images produced have higher resolution and can be seen more clearly. The sample is meticulously prepared, and is typically not made up of live cells; EM can be used in viewing subcellular components, such as organelles and can view structures as small as atoms at 1/10 000 000 of a millimeter, 10-10 m.

The correct option is (D) Electron microscopes use electron beams and electromagnetic lenses, while compound light microscopes use light and ocular and objective lenses.

A microscope is an instrument that is utilized to amplify small objects. A few microscope might be utilized to notice an object at the cell level, allowing researchers to see the state of a cell, its nucleus, mitochondria, and different Organelles.

Electron Microscope utilizes a light emission and their wave-like qualities to magnify an object's image. The Light Microscope employs visible light to detect tiny objects.

Hence, the correct option is D.

For this assessment, you will write a short story.1. In your story, you will pretend that you are traveling in an area and notice different plants, animals, and other species. You can use your imagination and create pretend organisms, or use examples of real organisms. 2. You will use examples that demonstrate each of these types of relationships: predator-prey, commensalism, mutualism, and parasitism. You may not use the same examples given in this lesson. 3. In your story, be sure to compare and contrast the relationships that you observe. Each time you present a new example compare it to a previous example. You may want to use the chart in the lesson for guidance.
