Answer:
Gas exchange between tissues and the blood is an essential function of the circulatory. The air contains oxygen that crosses the lung tissue, enters the bloodstream, and the alveoli are in direct contact with capillaries of the circulatory system. As water flows over the gills, oxygen is transferred to blood via the veins.
Explanation:
Limiting factors for snakes can include frogs, grasshoppers, farmers, pesticides, weather, climate, the environment, and various other abiotic and biotic factors.
Those specified however were also specified within the prompt. These are limiting factors because they can limit or help excel the snake population growth, yet in this prompt it is shown to greatly diminish the growth.
Hope this helps!
A cross between two linked genes was done in coupling configuration and in repulsion. In coupling, the recombination frequency is greater than 1/16 and in repulsion, the recombination frequency is less than 1/16
If the cross between two linked genes is in coupling, then the recombination frequency is greater than 1/16 having the genotype aabb and phenotype ab.
If the cross between two linked genes is in repulsion, then the recombination frequency is less than 1/16 having the genotype aabb and phenotype ab.
Coupling is the gamete entered having genes from identical parents having same inheritance.
Repulsion is the gamete entered from different parents having separate inheritance.
Genes in coupling configuration on a homologous chromosome have two wild alleles and two mutant alleles on the other homologous chromosome.
Genes in repulsion configuration have a wild allele on one gene and the second gene on other homologous chromosome having a mutant allele.

Answer:
Radial symmetry
Explanation:
One of the most prominent features of echinoderms is their radial symmetry. This means that if we divide the organism around any main axis it should be divided in two exactly similar halves across any plane passing through the body. This is because the mouth is surrounded by a central disk that contain specific structures called podia that radiate outwards and gives the radial symmetry to organism.
For example: The body of ctenophores, echinoderm, sea-anemone and many sponges have radial symmetry. Some echinoderms that have radial symmetry include sea urchin, Sea cucumber, bitter star etc.
