Answer:
The correct answer would be - 25%.
Explanation:
It is given that the Blue flower is dominant over the yellow flower which means Blue is represented by allele B here and allele b for yellow and Bb is a heterozygous case with a blue phenotypic character. Similarly, the Tall plant is dominant over short and represented by T and t respectively.
BbTt is a heterozygous condition and a cross with itself will produce :
Gametes: BT Bt bT and bt
BT Bt bT bt
BT BBTT BBTt BbTT BbTt
Bt BBTt BBtt BbTt Bbtt
bT BbTT BbTt bbTT bbTt
bt BbTt Bbtt bbTt bbtt
Here 4 out of 16 offspring are heterozygous for both traits represented by bold alphabets. Therefore the correct answer is 25%
A farmer crosses a purple-flowered pea plant with a white-flowered pea plant and plants the seeds. The farmer observes that all offspring have purple flowers. What BEST explains the lack of white flowers in the offspring?
Note about the question:
Probably there are options for this question, but I failed in finding them. However, in the explanation box I will explain the reason for the lack of white flowers in the F1.
Answer:
The purple phenotype is dominant over the white phenotype. The allele that expresses the purple color is dominant and, in a heterozygous state, hides the expression of the recessive allele that expresses the white color. Principle of dominance.

There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?
Answer:
to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
Explanation:
Firstly, let us calculate the number of calories burnt in 2 hours
in 10 minutes; 30 calories are burnt
∴ in 1 minute 30/10 calories are burnt = 3 calories are burnt
2 hours = 120 minute
∴ in 120 minutes 3 × 120 = 360 calories are burnt.
Next, let us calculate the amount of trail mix that contains 360 calories
100g of trail mix = 450 calories
450 calories = 100 g
1 calory = 100/450
∴ 360 calories = 360 × (100/450)
= 360 × 0.222 = 80g
∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Explain why when the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.
Answer: Each strand act as a template strand for another strand this way two strands are responsible for the production of two new strands. This way after the replication process two DNA molecules are produced.
Explanation:
S phase of the cell cycle is the synthesis phase of the cell cycle. This phase occurs after the interphase of the cell cycle. In this phase, the replication and synthesis of the DNA occur. The genetic material gets copied and doubled in this process before it enters into mitosis or meiosis. Each strand is utilized as a template strand for the synthesis of the complementary strand this way two molecules of DNA are produced. This way each cell contains a diploid set of chromosomes before it undergoes cell division into daughter cells in mitosis or meiosis.
Each strand act as a template strand for some other strand this manner strand is accountable for the manufacturing of new strands. In this manner after the replication system DNA molecules are produced.
S phase of the cell cycle is the synthesis section of the cell cycle. This section happens after the interphase of the cell cycle. In this section, the replication and synthesis of the DNA arise. The genetic material receives copied and doubled on molecular this system earlier than it enters into mitosis or meiosis.
Each strand is applied as a template strand for the synthesis of the complementary strand this manner molecules of DNA are produced. In this manner, every cell carries a diploid set of chromosomes earlier than it undergoes cell department into daughter cells in mitosis or meiosis.
What is the S phase?S phase (Synthesis Phase) is the section of the cell cycle wherein DNA is replicated, taking place among the G1 phase and G2 phase. Since correct duplication of the genome is essential to a successful cellular department, the techniques that arise for the duration of the S-phase are tightly regulated and broadly conserved.
Hence it states that the DNA is being replicated during the S phase of the cell cycle, it copies each strand differently.

How do you think new proteins affect the fitness of children?
Answer:
it affects ALOT!
Explanation:
Although health initiatives promote increased physical activity in children, the physiologic outcomes have not been well characterized. This investigation examined the effects of programmed aerobic exercise on protein metabolism in children (n = 7; mean ± SEM: 9.14 ± 0.46 y old; weight, 32.1 ± 1.6 kg; height, 138 ± 2.5 cm; and body mass index, 16.21 ± 0.36 kg/m2 ) using 15N-glycine methodology. Boys (n = 5) and girls (n = 2) walked (5 d/wk, 3.2–6.4 km/d) for 6 wk. Criterion measures taken at baseline (Pre) and after the exercise program (Post) included anthropometric data, dietary assessment, nitrogen balance, nitrogen flux (Q), protein synthesis (PS), protein breakdown (PB) and net protein balance [(Net) = PS − PB]. After the walking program, there were no significant changes in body weight, fat-free mass or percentage of body fat, whereas height increased (P < 0.01). Energy and protein intakes were constant throughout the study. Nitrogen balance was significantly more positive Post than Pre (P < 0.05). There was a significant decrease in Q (P < 0.0001) with corresponding decreases in PS (P < 0.001) and PB (P < 0.01). These data provide the first evidence that programmed aerobic exercise alters whole-body protein utilization in healthy, nonobese children. Longitudinal studies are required to further examine changes in protein metabolism associated with increased physical activity in this population. In addition, findings suggest a need to evaluate nutrient requirements for healthy, physically active boys and girls.

which processes beings the formation of sedimentary rock?
Answer:
clastic sedimentary rock are made up of pieces of pre-existing rocks. pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. if the sediment is very deeply, it becomes compacted and cemented, forming sedimentary rock.
Explanation:
Hope this helped Mark BRAINLEST!!!!
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification. A sediment is a particle of solid, loose pieces of rocks (in the form of sand, silt, clay, and gravel), or the remains of living organisms. Sediment is material that has been eroded, transported and deposited by wind, running water, waves, and ice in a place.
These rocks can also form from by the evaporation of seawater, or the settling of the remains of organisms in a water body. Sediment can become compacted, cemented and are foundin layers. Sedimentary rock is often found in layers.
Sedimentary rocks are formed on or near the Earth's surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

photosynthesis
melting of icebergs
Pls HELP
Soil erosion may be caused by an interaction between the hydrosphere and geosphere.
What do you mean by soil erosion?Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice, snow, air, plants, and animals.
Soil erosion occurs primarily when dirt is left exposed to strong winds, hard rains, and flowing water. In some cases, human activities, especially farming and land clearing, leave soil vulnerable to erosion.
The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.
