Freda grows potted plants outside in the summer. When the weather is very hot, her plants need to be watered every day to keep them from wilting.

For a class project, Freda designed a system that would automatically water her plants at 10:00 p.m. on days when the temperature reached 90°F. These are the steps she followed to design it:

Freda researched automated watering systems.

She brainstormed different solutions, then chose that one that she thought would work the best.

She sketched a design of the system and listed the equipment she would need to build it.

Next, Freda wanted to build her system, but she discovered that she could not afford to buy all the materials.

What mistake did Freda make in her design process that kept her from completing her project?

A.
She did not communicate her solution to others.
B.
She did not account for cost constraints in her solution.
C.
She did not evaluate her product in order to improve its design.
D.
She did not include measurements in her design sketch.

Answers

Answer 1

Answer:

B.) She did not account for cost constraints in her solution.

Explanation:

She did everything right except for B.

If we are planning on building something that requires materials we don't already have, we should research the cost of the materials, and our budget.

Hope this helped :)

Ice cubes float in water because they are less

Answers

Answer: Ice floats because it is less dense than the water. Something denser than water, like a rock, will sink to the bottom. To be able to float, an object must displace fluid with a weight equal to its own weight. The fact that ice floats in water is a bit strange, because most substances are denser when they're solids.

scientific concept for the water cycle

Answers

Answer:

Evaporation, condensation, precipitation, Surface Runoff, Infiltration, transpiration

Explanation:

There are six important processes that make up the water cycle. These are:

Evaporation

Evaporation is the process where a liquid, in this case water, changes from its liquid state to a gaseous state. Liquid water becomes water vapor. Although lower air pressure helps promote evaporation, temperature is the primary factor. For example, all of the water in a pot left on a table will eventually evaporate. It may take several weeks. But, if that same pot of water is put on a stove and brought to a boiling temperature, the water will evaporate more quickly.

During the water cycle some of the water in the oceans and freshwater bodies, such as lakes and rivers, is warmed by the sun and evaporates. During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.

Condensation

Condensation is the opposite of evaporation. Condensation occurs when a gas is changed into a liquid. Condensation occurs when the temperature of the vapor decreases.

When the water droplets formed from condensation are very small, they remain suspended in the atmosphere. These millions of droplets of suspended water form clouds in the sky or fog at ground level. Water condenses into droplets only when there are small dust particles present around which the droplet can form.

Precipitation

When the temperature and atmospheric pressure are right, the small droplets of water in clouds form larger droplets and precipitation occurs. The raindrops fall to Earth.

As a result of evaporation, condensation and precipitation, water travels from the surface of the Earth goes into the atmosphere, and returns to Earth again.

Surface Runoff

Much of the water that returns to Earth as precipitation runs off the surface of the land, and flows down hill into streams, rivers, ponds and lakes. Small streams flow into larger streams, then into rivers, and eventually the water flows into the ocean.

Surface runoff is an important part of the water cycle because, through surface runoff, much of the water returns again to the oceans, where a great deal of evaporation occurs.

Infiltration

Infiltration is an important process where rain water soaks into the ground, through the soil and underlying rock layers. Some of this water ultimately returns to the surface at springs or in low spots downhill. Some of the water remains underground and is called groundwater.

As the water infiltrates through the soil and rock layers, many of the impurities in the water are filtered out. This filtering process helps clean the water.

Transpiration

One final process is important in the water cycle. As plants absorb water from the soil, the water moves from the roots through the stems to the leaves. Once the water reaches the leaves, some of it evaporates from the leaves, adding to the amount of water vapor in the air. This process of evaporation through plant leaves is called transpiration. In large forests, an enormous amount of water will transpire through leaves.

Suzanne has a cat and uses a pet carrier to take her cat to the veterinarian. After a few years, the cat runs away and hides everytime suzanne gets the carrier out. Which beat describes the cats behavior?

Answers

Answer:

C. Conditioned

Explanation:

Based on the reaction that the cat is having it seems that the cat has a conditioned response to the carrier being out. This means that the cat has a learned response that is directly associated with a certain stimuli which in this case is the carrier. Since he has a bad experience with the carrier before, he now reacts in a scared manner every time he sees it.

Answers

Answer:

Roots act like straws absorbing water and minerals from the soil. Tiny root hairs stick out of the root, helping in the absorption. Roots help to anchor the plant in the soil so it does not fall over. Roots also store extra food for future use.

The various functions of water in plants include: maintaining cell turgidity for structure and growth; transporting nutrients and organic compounds throughout the plant; comprising much of the living protoplasm in the cells; serving as a raw material for various chemical processes, including photosynthesis;

The primary functions of the stem are to support the leaves; to conduct water and minerals to the leaves, where they can be converted into usable products by photosynthesis; and to transport these products from the leaves to other parts of the plant, including the roots.

A plant has two organ systems: 1) the shoot system, and 2) the root system. The shoot system is above ground and includes the organs such as leaves, buds, stems, flowers (if the plant has any), and fruits (if the plant has any).

Tissues are further arranged or combined into organs that carry out life functions of the organism. Plant organs include the leaf, stem, root, and reproductive structures. The first three are sometimes called the vegetative organs and are the subject of exploration in this chapter.

Roots keep a plant in the ground. They also take in water and nutrients from the soil.

Leaves absorb sunlight, and make food for the plant by photosynthesis. ...  

The stem supports the leaves and flowers. ...  

Reproductive organs allow a plant to produce new plants.

Answers

Answer:

4. had certain inheritable traits that made them to survive

Explanation:

The options are:

1. produced offspring that all had identical inheritable characteristics

2. Did not face a struggle for survival

3. learned to migrate to a new environment

4. had certain inheritable traits that made them to survive

The correct option would be option 4.

This is law of natural selection at play. According to this law, organisms that are better suited to an environment survive, multiply, and pass their survival genes to their offspring. Those that are weakly adapted to the environment usually fade off the environment gradually.

Hence, other species of mammals exist today most likely because they had inheritable traits that made them to survive the changing environment while mammoths became extinct because they were poorly adapted to changing environment.

As the trait is dominant and controlled by a single gene, the mutation must have occurred on both diploid copies, true or false?? with reason please

Answers

Answer:

True.

Explanation:

Diploid copies are cells generated as copies of other cells and which have two homologous copies, exactly the same, of the cell that gave rise to it (the mother cell). In this case, if the mother cell has a mutation that causes a dominant characteristic and controlled by a single gene, it means that its diploid copies will have that same mutation, since they are exact copies.

Answers

Answer:

Plants obtain glucose in the process of photosynthesis while animals obtain glucose by eating other organisms.

Explanation:

Plants obtain glucose in the process of photosynthesis while animals obtain glucose by eating other organisms. In plants, carbondioxide is used as a raw material in the process of photosynthesis but also small amount of carbondioxide gas is released during respiration from stomata present on leaves while animals has lungs which helps in the removal of carbondioxide gas from the body during breathing.

Cellular respiration and photosynthesis are opposite to each other. respiration is energy releasing process while photosynthesis is a process in which food is produced.
