An advantage of asexual reproduction in plants is reproduction without another parent. This method allows plants to reproduce independently, ensuring that they can propagate in environments where mates are scarce or where conditions favor quick reproduction.

The correct answer is reproduction without another parent. Asexual reproduction allows plants to reproduce on their own, which can be advantageous in environments where finding a mate is difficult or when rapid reproduction is needed.
Genetic variation is beneficial because it (1 point)
can help a species better adapt to environmental changes.
requires only the sporophyte generation.
can increase mutations.
protects individuals in a species equally against disease.
can help a species better adapt to environmental changes.
requires only the sporophyte generation.
can increase mutations.
protects individuals in a species equally against disease.
Genetic variation is beneficial because it can help a species better adapt to environmental changes. This diversity allows for a greater range of traits within a population, increasing the likelihood that some individuals will possess characteristics suited for survival in changing environments.

Genetic variation is beneficial because it can help a species better adapt to environmental changes. This variability among individuals in a population increases the chances that some will possess traits that are advantageous for survival in new or changing environments.
In moss, the ____ is the dominant generation.
diploid gametophyte
haploid sporophyte
haploid gametophyte
diploid sporophyte
diploid gametophyte
haploid sporophyte
haploid gametophyte
diploid sporophyte
In moss, the haploid gametophyte is the dominant generation. Mosses exhibit a life cycle where the gametophyte stage is more prominent and longer-lived than the sporophyte stage, which is dependent on the gametophyte for nutrition.

diploid gametophyte
haploid sporophyte
haploid gametophyte
diploid sporophyte
diploid gametophyte
haploid sporophyte
haploid gametophyte
diploid sporophyte
In moss, the haploid gametophyte is the dominant generation. The gametophyte stage is the main and most visible part of the moss life cycle, while the sporophyte is usually smaller and dependent on the gametophyte for its nutrition.
Use the scenario to answer the question.
You investigate the effect of different concentrations of ethylene spray on ripening in bananas.
What would be the independent variable of this investigation?
(1 point)
the concentrations of ethylene spray
the age of the bananas
the color of the bananas
the length of ripening time
You investigate the effect of different concentrations of ethylene spray on ripening in bananas.
What would be the independent variable of this investigation?
(1 point)
the concentrations of ethylene spray
the age of the bananas
the color of the bananas
the length of ripening time
The independent variable of this investigation would be the concentrations of ethylene spray. This is the variable that you are changing or manipulating to observe its effect on the ripening of bananas.

The independent variable of this investigation would be the concentrations of ethylene spray. This is the factor that you are manipulating to see how it affects the ripening process of the bananas.
How does auxin affect the growth of plant stems? (1 point)
It builds on the side of the stem that faces the light source and stimulates growth.
It builds up on the side of the stem that faces the light source and inhibits growth.
It builds up on the side of the stem that is away from the light source and stimulates growth.
It builds up on the side of the stem that is away from the light source and inhibits growth.
It builds on the side of the stem that faces the light source and stimulates growth.
It builds up on the side of the stem that faces the light source and inhibits growth.
It builds up on the side of the stem that is away from the light source and stimulates growth.
It builds up on the side of the stem that is away from the light source and inhibits growth.
Auxin affects the growth of plant stems by building up on the side of the stem that is away from the light source and stimulating growth. This unequal distribution of auxin causes the cells on the shaded side of the stem to elongate more than those on the light-exposed side, resulting in the stem bending toward the light (a phenomenon known as phototropism).
How does auxin affect the growth of plant stems? (1 point)
A. It builds on the side of the stem that faces the light source and stimulates growth.
B. It builds up on the side of the stem that faces the light source and inhibits growth.
C. It builds up on the side of the stem that is away from the light source and stimulates growth.
D. It builds up on the side of the stem that is away from the light source and inhibits growth.
A. It builds on the side of the stem that faces the light source and stimulates growth.
B. It builds up on the side of the stem that faces the light source and inhibits growth.
C. It builds up on the side of the stem that is away from the light source and stimulates growth.
D. It builds up on the side of the stem that is away from the light source and inhibits growth.
The correct answer is C. It builds up on the side of the stem that is away from the light source and stimulates growth. This causes the stem to bend toward the light as the cells on the darker side elongate more than those on the lighted side.
