Explain incomplete dominance, using snapdragon
flowers as an example.

Answers

Answer 1

Answer:

Dominant allele does not completely conceal recessive allele.

Snapdragon with genotype Rr (R being red and r being white), would have a phenotype of pink flowers.

Explanation:

Incomplete dominance is where a dominant allele is not able to completely conceal a recessive allele, usually leading to a phenotype which appears to be a combination of the two.

For example, in snapdragons:

The allele for red flowers (R) is dominant over the allele for white flowers (r). Let's say a snapdragon flower had the genotype Rr, one allele for red flowers and one for white. In the case of 'normal' dominance the dominant red flower allele (R) would mask the effects of the recessive white flower allele (r), resulting in the phenotype (outward observable characteristics) of having red flowers.

However here in the case of incomplete dominance, the dominant allele would not be able to fully cover up the effects of the white flower allele, meaning that both colors (red and white) are expressed in the phenotype, resulting in pink flowers.

Hope this helped!

Answer 2

Answer:

Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.

Auxins cause cells to grow ___. A. Longer on the sunny side of the stem. B. Shorter on the sunny side of the stem . C.shorter on the shaded side of the stem .d. Longer on the shades side of the stem

Answers

Answer:

D. Longer on the shaded side of the stem

Explanation:

Auxin is a plant hormone that promotes cell growth and elongation in plant stems.

It causes the cells to grow longer on the shaded side of the stem.

This growth allows for the plant to grow in the direction of the light source it has.

So, the correct answer is D. Longer on the shaded side of the stem

Answers

Answer:

conduction up three different trees in a forest over 24 hours.

2.5

The graph suggests the amount of water table that is beneath the trees. The graphs also indicate the rate of conduction by the trees. The difference in the water table is considered to calculate the total volume of water consumed by the tree in 24 hours.

What is transpiration?

Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers.

The rate of conduction could be averaged and then the total volume used in 24 hours can be easily calculated by the product of the average rate of water conduction and 24 hours.

Which is true about the tundra biome?
a. It receives less direct sunlight than any other biome on earth.
b. It has more trees than any other biome on earth.
c. It can be found at low elevations all over the earth.
d. It has more types of plants and animals than any other biome on earth.

Answers

Answer:

It receives less direct sunlight than any other biome on earth.

Explanation:

The tundra biome is a cold, frozen landscape. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. Tundra form in two distinct cold and dry regions.

The Tundra biome is a frozen landscape that has a dark and cold environment. It receives less sunlight compared to other biomes. Thus, option a is correct.

What are the characteristics of the Tundra biome?

The Tundra biome is the biogeographical region that has the coldest atmosphere of all the other biomes and is marked by little precipitation, low temperatures, long winters, and short seasons for agricultural growth.

They are present in the Arctic circle as the temperature reaches below zero degrees celsius which can last up to ten months. It is mostly barren land and is majorly covered with willow trees, and birch trees. They receive very less amount of sunlight as they have a long winter season.

Therefore, Tundra receives less sunlight.

What are some ethical and philosophical questions that surround the issue of
genetic counseling? Might it sometimes be unwise to know ahead of time about
possible genetically linked disorders that might afflict your child or yourself?

Answers

Answer:

Genetic counseling raises concerns associated with confidentiality and privacy of the information. I consider that genetic information always is beneficial for the individual because this information can be used to determine the genetic predisposition of developing a particular inherited disease (and therefore prevent it).  

Explanation:

Genetic counseling has historically been associated with concerns with confidentiality and privacy of genetic information. Genetic information about an individual such as carrier status (i.e., the presence of recessive deleterious alleles in the genome of the individual), his/her chance of developing a certain disease (e.g., cancer), or transmit this disease to his/her offspring is always stigmatizing, and therefore it must be kept confidential. In consequence, genetic information must be carefully handled by professionals because any filtration of this information may be harmful to the individual (for example, unscrupulous companies might use this information to select personal regarding the genetic predisposition to suffer inherited diseases). However, genetic information is very useful in order to determine the genetic predisposition of developing a particular inherited disease and thus take the necessary actions to prevent it (e.g., avoid high salt foods if there is a genetic predisposition of developing cardiovascular diseases).

Answer:

Um, I'm guessing you don't need this answer anymore seeing that it was posted last year.... but I think that it is good to know if you child has genetically linked disorders that might afflict your child or yourself so that you can be prepared before hand.

As the level of Carbon Dioxide in the atmosphere increases, how will (is) primary productivity impacted? How does this impact populations of primary consumers?

Answers

Answer:

Rising atmospheric carbon dioxide (CO2) and nitrogen (N) deposition increase directly the resource availability to plants, and can increase plant growth and net primary productivity (NPP; Norby et al., 2005).

Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.

Explanation:

Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.

What do you mean by Net primary productivity (NPP)?

Net primary productivity may be defined as the amount of matter accumulated by plants per unit area in a given time.

Primary productivity depends on photosynthesis, where carbon dioxide gets converted to energy. If the level of Carbon Dioxide in the atmosphere increases, the photosynthesis rate increases, and finally the primary productivity increases.

Therefore, Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.
