Answer:

The way plants eat.

Explanation:

Plants do not eat like humans. They receive their energy from the sun. The process of energy conversion from the sun to the plant is called photosynthesis.

Answer:

False

Explanation:

Eukaryotes along with some prokaryotes also perform the process of photosynthesis. Photosynthesis needs chloroplast and it is also found in some of the prokaryotes.

Prokaryotes are primitive cells but they do have organelles like mitochondria and chloroplast.

Photosynthesis is the process by which glucose is made in the presence of sunlight out of which oxygen is released into the environment and carbon dioxide from the environment is used.

4. A male green parakeet breeds with a female blue parakeet: All the offspring are green. What trait is

Harman [31]

Answer:

4. Green

5. 1 Green : 1 Blue parakeet

6. 100% green offsprings

7. Violet color

8. 0%

9. 1 Yellow : 1 white sulfur butterflies

Explanation:

4. A dominant trait is that which masks the phenotypic expression of its contrasting trait in a gene. Hence, the cross between a green and blue parakeet produced offsprings that were all green because the green trait is dominant i.e. mask the expression of the blue trait.

5. An heterozygous green parakeet will have genotype:Gg while a homozgous blue parakeet will have genotype: gg. A cross between Gg and gg will produce offsprings with genotypes: Gg and gg in the proportion 2:2. This means the phenotypic ratio of Gg (green) and gg (blue) is 1:1.

6. A homozygous dominant parakeet means genotype, GG while a heterozygous green parakeet means genotype, Gg. GG and Gg, if crossed will produce offsprings with genotypes: GG, GG, Gg and Gg. Since the allele for green color (G) is dominant over the allele for blue color (g), all the offsprings i.e 100% will be green colored.

7. A purebred flower means a flower that produces only one type of color and is homozygous. Hence, let's say a purebred red flower will have genotype RR while a purebred violet flower will have genotype VV. Hence, these two purebreds will be crossed to produce offsprings that all possess genotype, VR. According to the question, they are all violet. This means that the allele for Violet color is masking the phenotypic expression of the red color. Hence, the Violet color is a dominant trait.

8. A homozygous Violet and red flower will have the genotypes: VV and RR respectively. A cross between them will produce an offspring with genotype, VR. Since the Violet allele is dominant, it will be phenotypically expressed over the red allele. Hence, none of the offsprings i.e. 0% will be red-colored.

9. A heterozygous sulfur butterfly will be Yy while a homozygous recessive sulfur butterfly will be yy. Where Y is yellow allele and y is white allele. If Yy and yy are crossed, offsprings with genotypes Yy and yy will be produced in the ratio 1:1. This means that the phenotypic ratio of the cross between a heterozygous sulfur butterfly (Yy) and a homozygous recessive sulfur butterfly (yy) is 1 Yellow sulfur butterfly: 1 white sulfur butterfly.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway.

<h3>Further explanation </h3>

Examine the accompanying wind rose diagram. Based on the information shown, determine the correct answers to the following questions.

Drag the appropriate labels to their respective targets. Note that there are twice as many blanks as answer choices. In other words, only half of the targets need to receive a label. Pay attention to the color coding and think carefully about the best position for each label when multiple locations seem possible.

The answer is: Wind direction impacts the design of airports, including the location and orientation of the runway. This relationship explains why planes circle above an airport so they can land in the correct orientation, and why they reorient themselves after taking off in a direction other than the direction they wish to fly. In our example, the longest spoke in the wind rose diagram indicates prevailing winds are coming from the NE and blowing toward the SW. Therefore, the correct orientation for the runway is along this path, with planes taking off in the SW to NE direction. This wind pattern can be found where NE trade winds are located.

The half-life of protactinium-226 is 2 minutes if you started with 20 grams of pa-226 how much do you have after 8 minutes

Hunter-Best [27]

Divide the amount in half for every 2 minutes

0 minutes = 20 grams

2 minutes = 20/2 = 10

4 minutes = 10/2 = 5

6 minutes = 5/2 = 2.5

8 minutes = 2.5/2 = 1.25 grams
