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.

The mechanism they use is cross pollination

Explanation:

Pollination can be known as transfer of the pollen from anther to the stigma. It can be from the one flower or different flower also. In gymnosperms, pollination occur from the cone of male to the female.

Cross Pollination: The pollen transfers from the flower anther of individual flower to the part of flower which is called stigma part of any another flower on a different individual of the common species.

Ben Affleck has a cleft chin, but his ex-wife Jennifer Garner does not. Neither one of their two daughters (Violet and Seraphina
kherson [118]

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc

Aliun [14]

Answer:

Sympathetic nervous system

Explanation:

The sympathetic nervous system of the autonomic division prepares the body for stress or emergency conditions by generating the “fight-or-flight” responses. The sympathetic nervous system triggers the release of stress hormones from the adrenal medulla to generate the set of physiological responses.

There is dilation of the pupil, and an increased rate of heartbeat and increased blood pressure. Other responses include dilation of airways and dilation of blood vessels that supply blood to skeletal muscles, heart muscles, liver, etc. Under the given emergency condition, the sympathetic nervous system of Meghan was activated to generate the fight or flight response.

The Correlated trait exercise shows that :
Karolina [17]

Answer:The correlated trait exercise shows that when two characters are correlated, the optimal values and selection strengths rise and fall together.

Explanation: Correlation refers to statistical (linear) relationship between two random variables. When traits are correlated, change in one is associated with change in the other.

Correlation coefficient (c.c.) measures strength of association between two variables in the same individual or experiment. It can range from -1 to +1. C.c. can be positive, negative or weak.

1. A positive c.c. means that an increase in one variable is associated with an increase in the other variable.

2. A negative c.c. means that an increase in one variable is associated with a decrease in the other.

3. A c.c. near zero indicates a weak relationship between the variables.

Correlation can be represented by scatter plot as shown in the attached image.
