.The pollen-producing structures of gymnosperms are locked away in cones and generally not accessible to insects. What mechanism
jeyben [28]

Answer:

Wind

Explanation:

Gymnosperms can be described as plants which lack flowers and fruits.

As they do not have flowers to attract insects like the angiosperms, they can, however, transfer their pollen through the wind. As pollen is very light in weight hence, it can be transported by the wind. The pollen transported by the wind usually results in self-pollination as the wind is not able to take the pollen to long distances.

In anatomic position, the radius lies _____ to the ulna. inferior superior posterior medial lateral
kondor19780726 [428]

Answer: lateral

The radius is a long bone in the forearm. In anatomic position, it lies lateral to the ulna, which is smaller than the radius. Both radius and ulna connect to the humerus bone of the upper arm at the elbow joint. The radius pivots around the ulna to create movement at the proximal and distal radio-ulnar joints. Moreover, radius articulates in elbow joint, proximal radioulnar joint, wrist joint and distal radioulnar joint.

Why do companies like nestle object to bottle deposit programs? what do they support instead?
Ahat [919]

Answer:

The companies take away the bottle as "security deposit and however they can recycle and reuse it."

Explanation:

When buying different beverages from a person distributing, a deposit needs typically to be paid to the distributor from the containers that have been taken. However, the distributor will issue a refund once the bottle that was taken has been returned to the place of purchase. Therefore, the distributor will reimburse the redemption of the retailer the amount that was deposited for every container. The additional handling fees usually added in some countries. The deposits that remain unredeemed are taken to the state or kept by distributors.

In pea plants, the allele for tall stalks (T) is dominant over the allele for short stalks (t). Suppose a cross between a tall p
vazorg [7]

Answer:

Tt - 1/2

tt - 1/2

Explanation:

<em>A cross between a tall pea plant and a short pea plant that produces 43 tall and 47 short offpsring (almost 1:1) is most likely a cross involving a heterozygous tall individual and a homozygous short individual.</em>

Tt   x   tt

Offspring = Tt   Tt   tt   tt (50% tall and 50% short)

If one of the tall offspring (Tt) is crossed with one of the short offspring (tt):

Tt   x   tt

Offspring = Tt   Tt   tt   tt

Genotype ratio = 2Tt:2tt

Hence,

Tt = 1/2

tt = 1/2
