Answer: your answer is A
Explanation: they are made of one or more cells :)
Answer:
Genotypic and Phenotypic ratios → 1:1:1:1
- 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair, SsWw
- 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair, Ssww
- 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair, ssWw
- 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair, ssww
Explanation:
<u>Available data</u>:
- spotted skin (S) is dominant over non-spotted skin (s)
- wooly hair (W) is dominant over non-wooly hair (w)
- Cross: heterozygous spotted, non-wooly mammoth with a heterozygous wooly-haired, non-spotted mammoth.
Parentals) Ssww x ssWw
Gametes) Sw, Sw, sw, sw
sW, sW, sw, sw
Punnett square) Sw Sw sw sw
sW SsWw SsWw ssWw ssWw
sW SsWw SsWw ssWw ssWw
sw Ssww Ssww ssww ssww
sw Ssww Ssww ssww ssww
F1) 4/16 = 1/4 = 25% of the progeny is expected to be SsWw, exhibiting spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be Ssww, exhibiting spotted skin and non-wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssWw, exhibiting non- spotted skin and wooly hair
4/16 = 1/4 = 25% of the progeny is expected to be ssww, exhibiting non-spotted skin and non-wooly hair.
Genotypic and Phenotypic ratios → 1:1:1:1
Answer:
The soft palate reflexively opens the nasopharynx to allow the passage of food is called bolus is not true. During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx. Soft palate elevation prevents bolus regurgitation into the nasal cavity
Explanation:
When food is ingested into the mouth, the tongue carries the food to the post-canine region and rotates laterally, placing the food onto the occlusal surface of lower teeth for food processing.During food processing, food particles are reduced in size by mastication and softened by salivation until the food consistency is optimal for swallowing.during food processing, the tongue and soft palate both move cyclically in association with jaw movement, permitting open communication between the oral cavity and pharynx.When a portion of the food is suitable for swallowing, it is placed on the tongue surface and propelled back through the fauces to the oropharynx.. The area of tongue-palate contact gradually expands backward, squeezing the triturated food back along the palate to the oropharynx.Pharyngeal swallow is a rapid sequential activity, occurring within a second.During the pharyngeal stage, the soft palate elevates and contacts the lateral and posterior walls of the pharynx, closing the nasopharynx at about the same time that the bolus head comes into the pharynx. Soft palate elevation prevents bolus regurgitation into the nasal cavity.
Answer:
<em>The correct option is C) The success of a species depends on the number of offspring that survive long enough to reproduce.</em>
Explanation:
Some species of animals such as the octopus might give rise to many offspring, but these offspring might not survive due to different reasons. Only a few of them will be able to survive until the age where they can reproduce.
On the other hand, the survival rate of offspring which are formed in lesser numbers is more. These offspring are taken care of by their parents usually or are better adapted to live in the environment. Hence, their survival rate is more.
