Which sequence correctly indicates the branching pattern of the human respiratory system?
A) trachea bronchi bronchioles alveoli
B) trachea bronchioles bronchi alveoli
C) alveoli trachea bronchioles bronchi
D) alveoli bronchioles trachea bronchi
Answer:
A
Explanation:
The system including tissues and organs needed for breathing and exchanging gases is called the respiratory system. It is essential for providing fresh air and eliminating the waste air from the body.
The branching pattern of the human respiratory system includes option A) trachea bronchi bronchioles and alveoli.
The Respiratory system can be explained as:The respiratory system includes the major organ lungs which along with some other tissues makes up the whole system. The trachea gets diverged into two branches named bronchi which further splits into lungs called bronchioles.The bronchioles spread throughout the lungs and have a sac-like small structure on its end called alveoli where the exchange of gases takes place.Therefore, option A is the correct sequence of respiratory branching.

How is the proportion of hydrogen to helium in the Sun's core changing over time?
Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.
Explanation:
The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.

What are some Characteristics of a ladybug after metamorphosis
Answer:
Ladybug physical characteristics
The ladybug has an oval-shaped body, six legs, two antennae, a head with two eyes, a thorax that is called a pronotum, and an abdomen (the part of the body that is covered by the elytra). When the pupa hatches as a new adult ladybug, it doesn't have any spots yet and its elytra are wet, soft, and pale colored.

Explain how DNA results in the expression of a gene using the following words: DNA, mRNA, tRNA, gene, transcription, and translation
Explanation:
in order for a gene to even be transcribed, it must be "turned on" or "expressed" meaning the nucleotides have moved away from each other. after it's expressed, the gene will unwrap and continue on with transcription, and make mRNA copy of a DNA strand. once RNA is made it will leave nucleus and enter cytoplasm to find a ribosome. once it attaches to ribosome, translation begins, and a tRNA will bind to anti-codon, and the building of a polypeptide/protein will begin.

Lionfish are native to the tropical waters of the Indo-Pacific. What conclusions can be made about the impact of climate change on the range of lionfish and, therefore, on biodiversity?
Answer:
The correct answer is - Climate change has restricted the habitat of lionfish. It has become an endangered species, reducing biodiversity.
Explanation:
As we know it is native to the tropical waters of the Indo-Pacific region. The change in the climate will increase the temperature of the water and this will lead to the restriction of habitat which lead to the reduction in the population of the fishes. As they live in the tropical climate they are habitual of warmer water and can not survive the climate change.
A tall pea plant with red flowers has the genotype TtRr. This plant is crossed with another tall pea plant with white flowers, having the genotype Ttrr. What is the probability of getting dwarf plants with red flowers in the F1 progeny
Answer:
1/8 or 12.5%
Explanation:
This question involves two genes coding for height and flower color in pea plant. The alleles for tallness (T) and red flowers (R) are dominant over the alleles of short (t) and white flowers (r).
According to this question, a tall pea plant with red flowers (TtRr) is crossed with another tall pea plant with white flowers (Ttrr). The following gametes is produced by each parent:
TtRr - TR, Tr, tR and tr
Ttrr - Tr, Tr, tr and TR
Using these gametes in a punnet square (see attached image), the following proportion of F1 offsprings will be produced as follows:
Tall, Red (T_R_) = 6
Tall, white (T_rr) = 6
Dwarf, red (ttR_) = 2
Dwarf, white (ttrr) = 2
The probability of getting dwarf plants with red flowers in the F1 progeny is 1/8 or 12.5%.

12.5

Answer: see below
Explanation:
So, kinetic energy means an object is already in motion. Potential energy, means an object has the potential to transfer energy but is idle. Mechanical energy is something like a wheel turning. That is also correlated with kinetic energy. Which in turn, means when a wheel rotates, the object is in motion. Therefore transferring energy.

In a cross Bb x Bb (B = Blue petals and b = pink petals), how many offspring will have the genotype Bb?
Answer:
2 offspring will have the genotype Bb.
Explanation:
Crossing the genotypes Bb and Bb results in 2, or 50% of the offspring having the genotype Bb. In the top right box, the B on the top and the B on the side make the BB genotype. In the top left box, B and b make the first Bb genotype. The lower right box crosses B and b to make the second Bb genotype. The last box in the bottom right crosses b and b, resulting in the genotype bb. So, after crossing the genotypes written on the top and side of the punnet square, 2 of the offspring will have the Bb genotype. (I got this by combining the letters outside the punnet square in the box where the row and column meet) .
