The apoplast in plant tissues consists of<u> cell walls, extracellular spaces, and vessel elements</u>

Explanation:

In plant cells, apoplasts refer to the extracellular space present outside the plasma membrane. These are formed by continuous cell walls arranged adjacent to each other.

The main function of apoplasts is transportation of water and other solutes between tissues and organs by free diffusion of molecules via the plasma membrane.

This pathway called the apoplastic pathway constituted by its vessel elements, cell walls, and extracellular space aids in passive absorption by roots

True or false? it is the medical assistant's responsibility to determine whether a patient has an advance directive in place
Mila [183]
The statement above is TRUE.
Medical advance refers to the document which a patient write down in advance in other to indicate the type of medical treatment he or she will prefer in case the person become so sick that they can not communicate this need to the health providers again.
The medical assistant in the hospital is the one who act as the patient's coordinator by providing means of communication between the other health providers and the patient. So, it is their duty to ensure that the patient has an advance directive in place.

qaws [65]

Answer:

a. the environmental variance (VE) = 3.5 g ²

b. 17.5 g ² for population

c. the heritability of broad sense (H2) = 0.83

Explanation:

a.With the information we have we can infer that environmental factors influence A, which is considered isogenic, thus, the environmental variance (VE) = 3.5 g ²

b.When studying population B, comparing it without environmental changes with respect to population A, we found that its total variance (VT) = 21.0g ²

We generate the following formula with the data obtained previously to find the genetic variation

VT = VE + VG

then VG = VT-VE

replacing data:

VG = 21.0 - 3.5 = 17.5 g ² for population

c. Regarding the heritability of broad sense (H2) in population B, we can reach the result with the data previously obtained like this:

H2 = VG / VT = 17.5 / 21.0 = 0.83

24. Name two types of pathways that help a body maintain homeostasis, and an example of each.
gavmur [86]

Answer:

See the answer below

Explanation:

Homeostasis refers to the maintenance of relatively constant internal body processes. This is done in two ways

  • <em>Negative feedbacks</em>
  • <em>Positive feedbacks</em>

Negative feedback returns body processes back to normal after the process has been breached. An example is when the body temperature becomes too high or too low. At too high temperature, vasodilation of the skin's blood vessels occurs and more heat is lost to the surrounding from the skin, sweat is also produced by sweat glands and evaporation of the seat causes cooling. At too low temperature, vasoconstriction occurs leading to the conservation of more heat. The muscles also shake to generate more body heat

Positive feedback ensures that a breach of body processes reaches completion. An example is when a pregnant woman starts laboring. The increase in the amount of oxytocin in the blood leads to the contraction of the uterus consequently leading to the opening of the cervix. More and more oxytocin leads to more frequent and stronger contraction of the uterus untill the baby is born.
