High levels of cytokinin and low levels of auxin

Growth of the shoot apical meristem is:

Inhibited by auixn.
b.

Not affected by auxin.
c.

The same in all plant species
d.

Responsible for formation of all above ground post-embryonic organs

Which of the following is NOT used as a mutagen in Arabidopsis

T-DNA
b.

blue light
c.

ems
d.

fast neutron radiation

Domestication of maize began:

a.

2,000 years ago
b.

6,000 to 10,000 years ago.
c.

in Asia
d.

both b and c.

Which of the following is a good reason to invest in algae as a bio-manufacturing platform?

a.

Algae can be used to produce diverse products such as colostrum and polyurethane.
b.

Algae have a high biomass yield compared to other crops.
c.

Algae are rich in protein.
d.

All of the above

Florigen was identified by which of the following approaches
a.

A genetic approach that involved the isolation of mutants.
b.

By isolating proteins from plant extracts.
c.

By grafting.
d.

By treating plants with auxin.

NOW, THE FOLLOWING QUESTIONS ARE FREE RESPONSE QUESTIONS (SHORT ANSWERS)

Science

People of Russian Heritage.

People of Polish Heritage.

People of Thai Heritage.

Read chapter 24, 22 & 36 of the class textbook(Transcultural Health Care. A Culturally Competent Approach (4th ed.)

Purnell, L.D.

Publisher: F.A. Davis Company; 4th edition)

and review the attached PowerPoint presentations.

Once done write an 800 words essay contracting the three study heritage.

Mention in the essay if there is any similarity in their healthcare belief. Mention how do they see health and disease and their customs to deal with them, also, discuss how they view dead. How their health care belief affect or influence the delivery of evidence-based healthcare.

Read content chapter 36 in Davis Plus Online Website.

You must use at least 4 evidence-based references (excluding the class textbook). A minimum of 800 words (not counting the first and reference page are required).

This time beside the content and references I will count the assignment base of the number of words.

Expansion of Mental Health or Substance Abuse Services: Business Plan

Science

Under the ACA, the expansion of behavioral health services is mandated for health care organizations. Whether your current health care organization already offers these types of behavioral services, or whether it will need to begin offering these types of behavioral health services, is subject to evaluation and goal setting by both the health care executive and the board of directors. As a current or future health care executive, you will likely engage in developing business plans for new initiatives and health care delivery service flows in your health care organization. With the recent move to address expanded behavioral health services in health care organizations, developing a business plan for expanded behavioral health services is both timely and appropriate.

Review the resources for this week and review the business plan template for this Assignment. Reflect on the major considerations your health care leadership team members need to keep in mind when developing a business plan for the expansion of either mental health or substance abuse services in your health care organization.

The Assignment: (5 pages)

  • The ACA has provided for increased coverage of mental health and substance abuse services; however, there remains a shortage of these services in health care organizations. Your role as a health care leadership team is to evaluate opportunities for expanded behavioral health initiatives. Develop a business plan to model the expansion of either mental health or substance abuse services within your health care organization.
  • Also, prepare your business development plan as a PowerPoint presentation.
