Producers use energy from the sun to create glucose (b), or usable chemical energy
New, inheritable characteristics can result from the recombination of genes during meiosis and <span>mutations in the genes found in sex cells. The correct option among all the options that are given in the question is the first option. I hope that this is the answer that has actually come to your desired help.</span>
suppose P is a dominant allele for a flower color and p is a recessive one.
The expected ratio of genotypes among the F1 offspring is 1 Pp : 1 pp.
The white pea bloom was "masked" in the F1 generation, which caused all of the flowers to be purple.
The "masked" genes from the F1 generation were permitted to mate, but they were only allowed to pair once, leaving the other three times to appear with purple flowers, resulting in a 3:1 ratio of purple to white blooms in generation F2.
He paired a homozygous dominant flower with a homozygous recessive flower in his initial attempt. As a result, all of the F1 generation's progeny were heterozygous, making them all purple.
Two heterozygous, one homozygous recessive, one homozygous dominant, and the progeny of the F1 generation were crossed with another heterozygous plant.

Answer:
In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats.
Explanation:
Carrying capacity refers to the maximum number of individuals of a certain species an environment can maintain in the long-term.
Factors that will determine carrying capacity include amount of water available in the environment, geographic size of environment, energy sources available, and so forth.
The image below shows the general idea of carrying capacity and population size:
The reality is often not so simple, as populations can overshoot their carrying capacity. When this happens, it takes some time for the population numbers to decrease. Thus, graphs more realistically resemble the one below:
Over time and with no disturbances, the population will generally max out at the carrying capacity. It is also important to remember that environments may not be unchanging, especially in certain time scales. For example, an increase in rainfall one year may mean that there is far more standing water available in the environment. Thus, mosquito populations will temporarily increase as the carrying capacity for them allows for higher numbers.
