Vertebrata

Vertebrata is a group that contains various organisms which possess vertebrae (backbones). Animals that belong to the group are called vertebrates, and they include mammals, birds, fish, amphibians, and reptiles. The backbones in the animals extends from the head to the tail, and it encloses and protects the main nerve cord. The body of vertebrates is divided into trunk, and tail regions. They also possess a unique tube shaped brain, a distinct head, and three pairs of sense organs.

Answer:

COMMENSALISM

Explanation:

The interaction of organisms with one another in an ecosystem is called SYMBIOSIS, if it involves two organisms of same or different species. One type of symbiotic relationship is COMMENSALISM, which is a relationship in which one organism benefits while the other neither benefits or gets harmed.

This is the case of the burdock weed and its association with cows, deers or people. The burdock weed benefits from the relationship by getting Its seeds that attaches to the cow's, deer's or human's skin via its hooked-tip burrs, transported to varying locations. Thus, helping to spread the plant. The cow, deer, or human does not benefit fron this relationship neither is it harmed.

Answer:

0.7

Explanation:

Using Hardy-Weinberg equation of genetic variation being constant when disturbing factors such has mutation and others are removed.

p² + pq + q² = 1 and p + q = 1

where p² is the frequency of the homozygous dominant genotype (RR) and q² is the frequency of the homozygous recessive genotype (rr) and 2pq is the frequency of heterozygous genotype (Rr). p represent the frequency of "R" and q represent "g". since the coefficient against the green/green homozygote is 0.30 then

the fitness of the green/green homozygote = 1 - 0.3 = 0.7

Which situation would most likely increase the carrying capacity for humans
vredina [299]

C. A new source of freshwater

Explanation:

The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.

In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.

  • A new source of freshwater provides new resources for the ecosystem.
  • In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
  • Water is essential for life.
  • Fresh water sources are incentives for choosing to live in a place or not.
  • A fresh water source increases the carrying capacity for humans in a certain region.
