A woman with type A blood (whose father was type O) has children with a man that has type O blood. Both individuals are heterozy

Fantom [35]

Answer:

Explanation:

A woman with type A blood (whose father was type O) meaning her genotype is AO mates with

Man that has type O blood (OO genotype)

Both are heterozygous for MN blood group and both also heterozygous for the FUT1 gene controlling the synthesis of the H substance (Hh)- which determines the expression of the A and B antigen.

Cross

A O M N H h

O AO OO M MM MN H HH Hh

O AO OO N MN NN h Hh hh

Type A- 1/2 O-1/2 type M- 1/4 MN-1/2 N- 1/4, type H- 3/4 h-1/4

Type A with M antigen:

1/2*1/4*3/4 = 3/32

Type A with M and N antigens:

1/2*1/2*3/4 = 3/16

Type A with N antigen:

1/2*1/4*3/4 = 3/32

Type O with M antigen:

1/2*1/4*3/4= 3/32

Type O with M and N antigens:

1/2*1/2*3/4 = 3/16

Type O with N antigen:

1/2*1/4*3/4 = 3/32.

The 3/4 value comes from the expression of Hh-3/4 (this determines if the A and B Angie will be expressed).

a) Name the structures that: i) Carry water and mineral salts to the leaf ii) Prevents too much water loss from the upper surfac

const2013 [10]

Answer:

a) i) Xylem

ii) Upper epidermis

iii) Stoma

iv) Chroloplast

v) Palisade cell layer

b) By a waxy layer on the cuticle of the leaf

Explanation:

The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.

The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.

What can you determine about mechanical energy from this graph?

Pachacha [2.7K]

Answer:

What can be determined from the graph includes;

a) The Mechanical Energy M.E. = 1.0

b) The initial K.E. = 1.0, The initial P.E. = 0

c) The period for the kinetic energy = The period for the potential energy = 0.25

d) The frequency of oscillation of the kinetic and potential energy = 4 Hz

e) The object starts with its maximum velocity

Explanation:

The equation between kinetic energy, K.E., potential energy, P.E. and total mechanical energy, M.E. is given as follows;

M.E. = K.E. + P.E. = Constant

From the graph, we have;

a) M.E. = K.E. + P.E. = 1.0

b) At time t = 0,

The initial K.E. = M.E. = 1.0, P.E. = 0

At time t = 0.125,

P.E. = M.E. = 1.0, K.E. = 0

c) The period for the kinetic energy, K.E. = The period for the potential energy, P.E. = 0.25

d) The frequency of oscillation of K.E. and P.E. = 1/T = 1/0.25 = 4 Hz

e) The object starts in motion with maximum velocity at time t = 0.
