B. computer chips made from silicon?
C. a pie made with blueberries?
D. earrings made from silver?

Answers

Answer:

C. A pie made with blueberries

Explanation:

Blueberries can be grown naturally, so they are a renewable resource.

Blueberries are renewable resources. Hence, option C is correct.

What are renewable resources?

Renewable resources are those natural resources that continue to exist even after their consumption. They are also known as flow resources.

Renewable resources include plants, biomass, ocean currents, energy, wind, solar energy, tides, waves, etc. All these things will continue to exist even after their consumption. They can be used repeatedly and do not run out.

Advantages of renewable resources:

They are cheap.They are easily available.They are eco-friendly.They are clean and efficient.

Copper, silicon, and silvers are minerals and non-renewable resources, and blueberries are plant products and hence, they are renewable resources. Therefore, option C is correct.

An individual has the genotype Aa Bb CC Dd ee FF. How many different types of gametes could it produce in terms of unique allelic combinations of these genes?

Answers

Answer:

64

Explanation:

The individual in this question with genotype: Aa Bb CC Dd ee FF has six (6) different traits encoded by six (6) genes. The diploid number of the organism in this question is 12, however, the number of possible allelic combinations in each gamete can be calculated by using 2^n where n = haploid number of chromosome or number of allele that can be in one gamete.

Using this simple formula, 6 possible alleles can be in the gamete of this organism with the above genotype, hence, the individual can produce 2^6 = 64 different types of gametes in terms of unique allelic combinations of these 6 genes.

Sun.
с
The rotation of the Moon on its axis.
The distance of the Moon to the Sun.
D

Answers

Answer:

B

Explanation:

The reason we see different moon phases is because of how the sun, earth and moon are relative to each other .

Answer:

As the Moon orbits our planet, its varying position means that the Sun lights up different regions, creating the illusion that the Moon is changing shape over time. The best way of getting to understand the lunar phases is to regularly go out on a clear night when the Moon is in the sky and observe it.

Explanation:

Actually, the Moon rotates in the same period that it revolves, so we always see the same side (the white arrow keeps pointing to Earth). The differences in the Moon's appearance from one night to the next are due to changing illumination by the Sun, not to its own rotation.

Examine the cell diagrams shown. Which of the following choices identifies the eukaryotic cell for the correct reason?

Select one:
a. Because it contains organelles
b. Because it is a single cell
c. Because it contains genetic material
d. Because it is much smaller

Answers

Answer:

Option a

Explanation:

A eukaroytic cell contains more organelles than prokaryotic cells, and it is much bigger and complex.

hope this helps and is right :)

The choice that identifies the eukaryotic cell for the correct reason would the presence of organelles. The correct option would, therefore, be A.

Eukaryotic cells differ from prokaryotic cells such that:

Eukaryotic cells have nucleus, prokaryotic cells do not. The genetic materials of prokaryotic cells lies freely within the cytoplasm.Eukaryotic cells have membrane-bound organelles while prokaryotic cells do not. In size, eukaryotic cells (10 - 100 microns) is much bigger than prokaryotic cells (0.1 - 5 microns).

In the images, the organelles of the eukaryotic cells can be seen while the smaller size of the prokaryotic cell can also be observed.

write a letter to the government explaining the dangers posed by global warming/climate change​

Answers

Answer:

Global climate change has already had observable effects on the environment. Glaciers have shrunk, ice on rivers and lakes is breaking up earlier, plant and animal ranges have shifted and trees are flowering sooner.  Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves. Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century.

using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations of a leaf for photosynthesis​

Answers

Answer:

thanks

Explanation:

Leaves are adapted for photosynthesis and gaseous exchange.

They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.

When water evaporates from the leaves, resulting in more water being drawn up from the roots, it is called transpiration.

To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.

Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.

Plants have two different types of 'transport' tissue, xylem and phloem. These specialised tissues move substances in and around the plant.
