Answer:
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells.
Explanation:
Answer:
A) The fennec Fox is an omnivore.
E) The rock squirrel, spiny lizard and fennec fox are all primary consumers.
Explanation:
Fennec fox is omnivore and they usually live in underground holes. They dig the holes with the help of their feet. They usually consume insects, some plants, eggs and small animals.
Answer:
the level of carbon dioxide in Earth's atmosphere has been rising consistently for decades and traps extra heat near the surface of the Earth causing temperatures to rise
Vernal pools are unique wetland habitats where some of the state’s most recognizable reptiles and amphibians can be found. Vernal pools are small, shallow wetlands that do not have a permanent inlet or outlet of water flow. They fill in the fall or spring when rain or snowmelt drains into shallow depressions, and can retain water due to non-porous soils. Vernal pools only hold water for part of the year and experience a drying phase every year or every few years, usually in late summer.
Because their aquatic habitats are temporary, animals that depend on seasonal pools are adapted for both aquatic and terrestrial habitats at different life stages. These animals also benefit from the dry phase, because it prevents year-round water-dependent animals like fish from living in the pools. Fish prey heavily on eggs and larvae, and without seasonal pools some species would not be able to compete and reproduce. Although there are obvious challenges for an animal using an aquatic environment that disappears for part of the year, the benefit is a habitat free from predation by fish.
The right answer is C
An allele is a variable version of the same gene, because a gene can have several versions of the same gene, which can give slightly different structural proteins due to these variations in the DNA, thus, giving different phenotypes.
In most cases, the multiplicity of alleles in a gene gives phenotypic variation in the population due to their different expression. Therefore, the larger the number of alleles, the greater the number of phenotypes in the population.
To a lesser extent (more rarely), some variation can be a deletion giving non-functional proteins, causing rare diseases (like cystic fibrosis, hemophilia, sickle cell anemia).
