Answer: 16 different gametes

  1. ABCD
  2. ABCd
  3. ABcD
  4. ABcd
  5. AbCD
  6. AbCd
  7. AbcD
  8. Abcd
  9. aBCD
  10. aBCd
  11. aBcD
  12. aBcd
  13. abCD
  14. abCd
  15. abcD
  16. abcd

Explanation:

Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.  

The number of gametes with different combinations is 2ⁿ, where  

n = number of homologous pairs.  

In the exposed example there are 4 pairs of chromosomes, so

the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16

Individual: AaBbCcDdEe

You can make use of the fork line method to easily figure out the possible gametes.

A.......B.........C........D → ABCD

                     ........d → ABCd

          ...........c.........D → ABcD

                       ........d → ABcd

           b.........C........D → AbCD

                     ........d → AbCd

          ...........c.........D → AbcD

                       ........d → Abcd

a.......B.........C........D → aBCD

                     ........d → aBCd

          ...........c.........D → aBcD

                       ........d → aBcd

           b.........C........D → abCD

                     ........d → abCd

          ...........c.........D → abcD

                       ........d → abcd

Each of the following statements concerning hair is true except
Levart [38]

Answer: A. scalp hairs grow constantly throughout life.

Explanation:

Hair is a squamous keratinized epithelium which is consist of multi-layered flat cells.  Hair are made up of protein called "keratin".

The statement "scalp hairs grow constantly throughout life" is false because at a particular age or due to several factors scalp hairs stop growing.

Scalp hair growth rate depends on three main factors including sex (female hair grows faster than male), age (hair growth slows with age), and ethnicity (Asian hair grows slower than Caucasian hair).

Scalp hair growth stops because of  follicle devitalization when the hair length become two or three feet.

Hence, the correct answer is A. "scalp hairs grow constantly throughout life".

Roundworms are what type of biohazard?
BlackZzzverrR [31]

Roundworms can be included in the Virus/parasite biohazard category

  • A biohazard is a biological substance that is dangerous to the health of living organisms (especially humans) and/or the environment.  

  • Biohazards include different harmful microorganisms (e.g., bacteria), viruses, biological toxins, fungi, parasitic worms, etc.

  • Biohazards also include biological vectors that transmit diseases (e.g., mosquitoes, ticks, rodents, etc).

  • Roundworms are small organisms (nematodes) that may infect dogs and cats. Animals become infected when they ingest eggs that contain infective larvae.  

  • These small organisms (roundworms) can live in the digestive tract (i.e., intestines) and cause health problems including, among others, abdominal pain, fever, diarrhea, etc.
