The seed capsules of the Himalayan balsam plant explode when touched and can eject seeds as far as 16 feet from the parent plant. Is this a structural adaptation, behavioral adaptation, or both?
Answers
Answer:
behavioral adaptation
Explanation:
A structural adaptation is defined as the adaptation in which physical features of organisms or plants while behavioral adaptation is defined as the activities an organism or plant do to survive.
The Himalayan balsam plant is an example of behavioral adaptation because it disperse its seeds when it ripe and touched by someone, for its survival it shows it dispersal behavior and spread seeds as far as 16 feet from the parent plant. In the fear of someone can harm by touching it, the survival instinct of balsam plant shows behavioral adaptation.
Hence, the correct answer is " behavioral adaptation".

where does the energy for active transport come from
Answers
Answer:
Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy. Energy for the process is acquired from the breakdown of glucose using oxygen in aerobic respiration. ATP is produced during respiration and releases the energy for active transport.

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
Answers
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.

In a cross Bb x Bb (B = Blue petals and b = pink petals), how many offspring will have the genotype Bb?
Answers
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) .

Answers
Answer:In rare cases, a male cat can inherit two X chromosomes in addition to his Y chromosome (Klinefelter Syndrome). ... If the two X chromosomes do not carry the same allele (i.e., the cat's genotype is XBXbY), then the male will express calico coloration, just as a female would.
Pepsin is an enzyme produced in the stomach. Pepsin has an optimum pH that is very acidic, between a pH of 1.0 and 2.0. In an
experiment involving the enzyme pepsin, the pH is raised from 2 to 11. What will be the MOST LIKELY effect of this on the reaction?
Answers
Explanation:
the pepsin enzyme will not be able to work in a basic medium when ph raised from 2 to 11 it's efficiency will be affected and will not be in a condition of digesting protein .
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you .
When the pH is raised from 2 to 11 the most likely effect on the reaction is ;
The rate of reaction will decrease/delayed
Given that Pepsin enzyme has an optimum pH of 1.0 to 2.0, it will perform efficiently as a catalyst in an experiment whose pH levels fall within the range of the optimum pH of Pepsin.
Pepsin enzyme accelerates the digestion of proteins therefore when the pH levels are raised above 2.0 the efficiency of Pepsin enzyme will be negatively affected and the digestion of protein will require a higher activation energy.
Hence we can conclude that When the pH is raised from 2 to 11 the most likely effect on the reaction is The rate of reaction will decrease/delayed.
