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.

What causes the appearance of the Moon to change over time?
A
The orbit of the Earth around the Moon and its distance from the Sun.
B
The Moon's position relative to the Sun and Earth as it revolves around
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.

What affect does the Sahel's climate and physical characteristics have on population distribution?

Answers

Answer:

The Sahel has been labeled as one of those regions with the danger of overpopulation. It has been described with adjectives such as semi-arid, hot, dry, windy or sunny.

Sources have it that the G5 Sahel countries which include Mali, Niger, Burkina Faso, Mauritania, Chad will increase from about 84 million inhabitants in 2019 to 197 million in 2050. This projection includes people under 15 years of age which comprise about 50% of the entire population.

The climate itself doesn't seem to deter population growth. What seems to be occurring is sedentarization. This is due to rapid desertification and drought which have persisted for some time.

Explanation:

Sedentarization refers to the choice of a group of people who usually are very nomadic or migratory to settle permanently in a place.

This is usually due to a more favorable weather and topography which supports agriculture.

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.

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the tenth place and do not include units.)

Answers

Answer:

See Explanation

Explanation:

The question is incomplete as the diameters of the Willapa Bay urchins were not given.

However, I'll give a general way to solve this problem.

Average is calculated using:

[tex]Average = \frac{\sum x}{n}[/tex]

i.e. Sum of all diameters divided by the number of bay urchins.

The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.

10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm

Using the above data, the average is:

[tex]Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}[/tex]

[tex]Average= \frac{86}{10}[/tex]

[tex]Average= 8.6[/tex]

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:

Leaves have an increased surface area in order to increase light-harvesting and they are thin in order to increase the diffusion rate

Explanation:

Leaves have several adaptations to increase the photosynthesis rate. In the first place, leaves have a large surface area to increase light-harvesting and thus also increase photosynthetic energy conversion. Moreover, leaves are sufficiently thin to increase the gas exchange surface area, i.e., the entry of carbon dioxide (CO2) and the exit of oxygen from photosynthesis, which move by diffusion through stomata.
