Medulla is a set of cells that run through a piece of hair. Forensic scientists use them to determine which creature the hair came from.
Answer:
3/16
Explanation:
This question involves two different genes coding for earlobe shape and earwax quality. The alleles for attached earlobes (A) and wet earwax (E) are dominant over the alleles for free earlobes (a) and dry earwax (e).
According to this question, two humans mate who are heterozygous for both genes i.e. AaEe × AeEe. Each parent will produce the following gametes: AE, Ae, aE, ae.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
* Attached earlobe, wet earwax (A_E_) = 9/16
* Attached earlobe, dry earwax (A_ee) = 3/16
* Free earlobe, wet earwax (aaE_) = 3/16
* Free earlobe, dry earwax (aaee) = 1/16
Hence, the probability of these parents having their first child with dry earwax (ee) and attached earlobes (A_) i.e. genotype A_ee is 3/16.
Answer:
-S-phase
-Late telophase
Explanation:
The cell cycle is divided into two main phases: interphase and mitotic phase.
Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division (mitotic phase).
Mitotic phase is subdivided into four phases: prophase, metaphase, anaphase and telophase. At the end of prophase, nuclear envelope breaks down and condensed chromosome (DNA structures) are released.
During the late telophase, nuclear envelope is reformed.
Question #1:
Describe the role of Xylem in Photosynthesis
Answer:
Plants contain a branches system of tubes called Xylem. It is responsible for water transport from the roots to the leaves, where it's used for Photosynthesis.
Question #2:
Describe the role of Phloem in Photosynthesis
Answer:
Alongside Xylem, there is Phloem which is responsible for transporting glucose, which is formed during Photosynthesis.
