Bonds between atoms form and break during chemical reactions. Relate this forming and breaking of bonds to changes in energy.

Answers

Answer:

Explanation:

Energy is absorbed to break bonds. Bond-breaking is an endothermic process. ... Bond-making is an exothermic process. if a reaction is endothermic or exthermic depends on the difference between the energy needed to break bonds and the energy released when new bonds form.

In all types of chemical reactions, bonds are broken and reassembled to form new products.

In exothermic, endothermic and all chemical reactions it takes energy to break existing bonds and energy is released when the new bonds are formed.

Although compound microscopes and electron microscopes have some similarities, only _____________ microscopes use light and lenses to magnify objects.
please help me

Answers

Answer:

ORDINARY LIGHT  

Explanation:

Compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.

What are light microscopes?

A light microscope is an apparatus or tool used in biology labs that employ visible light to find, magnify, and enlarge very minute things. Utilizing lenses, they concentrate light on the specimen, magnifying it to create a picture. In most cases, the specimen is positioned near the tiny lens. The types and quantity of lenses that make up the microscope have a significant impact on the microscopic magnification.

There are two types of microscopes based on the number of lenses used: simple light microscopes, which have low magnification due to the use of a single lens, and compound light microscopes, which have higher magnification than simple light microscopes due to the use of at least two sets of lenses an objective lens and an eyepiece.

The lenses are positioned such that they may bend light for effective picture magnification.

The light microscope's capacity to make a picture by focusing a beam of light through a tiny, transparent object is the foundation for how it works. The picture is then magnified for viewing through one or more lenses. The specimen's transparency makes it simple and quick for light to enter. Bacteria, cells, and other microbial particles can all be included in specimens.

Therefore, although compound microscopes and electron microscopes have some similarities only light microscopes use light and lenses to magnify objects.

How do you think the scientific method can be used the rate of photosynthesis?

Answers

This activity is designed for students to:
1) learn that the rate of photosynthesis is influenced by environmental factors that can be quantified
2) understand the equation of photosynthesis and how the structure of a leaf allows for the required gas exchange to occur through the stomata
3) properly design an experiment with one variable, analyze results and report findings to the class
Students will use higher order thinking skills throughout this activity. They will need to use critical thinking to design the experiment and analyze the collected data. They will improve their observing, questioning and communicating skills. The students will need to determine if the question they have chosen to test, is indeed testable. The teacher will guide students to problem solve as they design and modify the experiment to insure only one independent variable is being tested during the experiment.

The students will learn specific concepts during the activity. The students will learn that:
1) the variables of light intensity, temperature, carbon dioxide, light quality all influence the rate of photosynthesis.
2) photosynthesis requires carbon dioxide to furnish the carbon required to make glucose. This carbon dioxide will be supplied by sodium bicarbonate dissolved in the water with the plant leaf disks
3) the stomata opening is controlled by the guard cells and that water, carbon dioxide and oxygen all pass through the stoma openings
4) food production for animals and humans on earth is dependent on plants. By increasing the use of carbon dioxide by plants, it may help slow global climate change. In turn, climate change (warmer in some regions, cooler in other regions) may affect various species of plants differently.

Human caused climate change (most notably, global warming) has many positive feedback loops intrinsic to itself. Please describe at least one of these loops and explain how it is potentially dangerous for habitability of the earth.

Answers

When we burn fossil fuels to produce electricity, heat, and more, they emit greenhouse gases (GHGs) like carbon dioxide (CO2) and methane. These gases trap the sun’s energy in Earth’s atmosphere as heat. As more and more GHGs are released, more heat gets trapped and the planet warms up, disrupting the long-standing, delicate climate systems that have made life on Earth possible.

The stronger storms and longer droughts we see becoming a dangerous new normal are a direct result. But how these impacts play off each other is far more nuanced. In many cases, the wildfires or disappearing glaciers we see in the headlines have unseen knock-on effects that lead to, well, more wildfires and disappearing glaciers.

Sometimes animals have traits that don’t seem to make sense, like the long tail feathers of a peacock. Suggest a reason for traits that don’t help an animal survive. Hint: those features might help them do other things.

Answers

Such traits listed may help them reproduce. For example, female peacocks tend to breed with males with certain types of tail feathers. While the feather themselves don’t guarantee survival, they certainly increase the chances of their genes being passed down. This can also be seen in humans. Certain characteristics in humans can be considered attractive. While these traits don’t necessarily increase the chances of survival, they do increase the chances of finding a mate and eventually having kids. This results in the dominant traits getting passed down.

Some traits in animals are more to attract their mates, to reproduce, these traits increase the chances of increasing the population of that animal.

What are courtship display?

Courtship display is the group of behaviors that animals show to attract their mates.

Generally, the males have bright colors and attractive features to attract females.

The behaviors are vocalization, beauty, bright colors, different types of features.
