The enforcement of hunting regulations are conservation measures that promote the?
preservation of species
What do national parks promote?
They promote a safe environment where you can have fun and let loose and enjoy some activities in a natural environment. The parks promote conservation of our native species of plants and animals.
Why do plant species need to promote cross-fertilization rather than self-fertilisation?
Self- and Cross-Fertilization in Plants. I. Functional Dimensions, by David G. Lloyd and Daniel J. Schoen © 1992 The University of Chicago Press.AbstractMany functional-ecological, morphological, and physiological-factors affect the occurrence of selffertilization. Six modes of self-pollination are distinguished. These differ in whether they utilize specialized flowers, whether they involve the transfer of pollen within or between flowers, whether they are autonomous or mediated by vectors, and their timing relative to opportunities for outcrossing. The various modes of selfing are subject to different structural constraints. Prepotency, the preferential success of cross-pollen in achieving fertilizations when it competes with self-pollen, influences the frequency of selffertilization in some species. The amount of self-fertilization may depend on environmental conditions and the vector species visiting each flower and may vary among the flowers of one plant. To gain information on the prevalence of autonomous self-pollination, 66 species for which the degrees of selfcompatibility and autofertility (seed set in isolation) have been published were surveyed. Partially selfincompatible species (in which the seed set is lower after self-pollination than after separate outcrosses) have on average lower autofertility than self-compatible species (in which self- and cross-pollinations succeed equally well), but some partially self-incompatible species have considerable autofertility and some self-compatible species have none. A number of features of floral morphology and phenology are associated with high Autofertility Indices.
The creation of wildlife refuges and the enforcement of game laws are conservation measures that promote increased?
Preservation of species
Trypsin inhibitors in tomato potato and alfalfa plants are best described as factors that?
promote species survival
How does the creations of variations in species promote survival?
Creation of variation occurs in a species and help in the survival to species as the most suitable or favorable character pass next generation and under unfavorable condition only the most fit organism survive and help in continuation of the species.
How can you reduce the problem of too many people on your planet?
Let God worry about it or the Secular answer: Get another planet or don't promote your species.
Why do plant species need to promote cross-fertilisation rather than self-fertilisation?
Pls replied the question to the answer back and I need the answer by tomorrow.
Why do plant species need to promote cross fertilization rather self fertilization?
Becuase when they self fertilize they cannot get the proper amount of sunlight, but when they dont self fertilize they can get the proper amount of sunlight
Can you plant a Lorax tree?
The "Lorax tree" is a fictional species from Dr. Seuss's book "The Lorax." In reality, you cannot plant a Lorax tree as it does not exist. However, you can plant real trees to help the environment and promote sustainability.
Why is it important to balance the ecosystems in parks?
Balancing ecosystems in parks is important as it helps maintain biodiversity and the overall health of the ecosystem. When one species becomes too dominant or extinct, it can disrupt the delicate balance and negatively impact other species. By ensuring a balanced ecosystem, parks can support a wide variety of plants and animals, promote natural processes like pollination and nutrient cycling, and protect against the spread of invasive species.
What can you learn from the zoo?
Visiting a zoo can teach you about different animal species, their habitats, behaviors, and conservation efforts. It can also help raise awareness about wildlife conservation and the importance of protecting endangered species. Additionally, zoos can offer educational programs and experiences that promote a greater understanding and appreciation of the natural world.
