Cephalization is the concentrated nerves in which it is at the front end. Aka the brain in which it is nerves throughout the brain and connects with the lining body of an organism. Furthermore organisms such as worms have small brain,of concentrated nerves. Primate is the most complex aka human since we have big and fragile cephalization at the head.
Answer:
Polar Bears feed on seals. So, polar bears and seals share a prey predator relationship. If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
Explanation:
Complete the paragraph based on this food web: Polar bears feed on seals. So, polar bears and seals share a _prey predator_.Climate change has caused ice caps to melt in colder regions where polar bears live. This change has caused them to hunt less. This situation will lead to_?extinction?_ 1 prey-predator relationship mutual relationship parasitic relationship. 2 less biomass in the quaternary level increased biomass in the quaternary level less biomass in the primary level.
If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.
Answer: e. HT
Explanation:
Gametes are sex cells, which can be an egg or a sperm. <u>They only have one allele of each gene</u>. Head shape is a trait coded by one gene (H) and tail length is another trait coded by another gene (T) Organisms are diploid, this means they have two alleles for each gene, so in this example the animal is HhTt. But, as it was said before, gametes only have one allele of each gene, then <u>the gametes produced will be: HT, Ht, hT and ht. </u>
From the options provided, the only one correct is HT.
- Hh is not correct because it has two alleles of each gene (Hh)
- tt is not correct for the same reason, two alleles of each gene (tt)
- T is not correct because the allele fo the other gene (H or h) is missing
- HhTt is not correct because it has two alleles of each gene
100% shore its B hope that helps you good luck
