True or false? Populations within ecosystems live in harmony and do not compete with each other.
Rainbow [258]
False in order for an ecosystem to survive there has to be some sort of competition. for example, if there were no sharks to eat little fish the little fish would over populate and then the little fish would run out of food which then means that whatever the little fish ate is now extinct and so on hinting the food chain's name. If it wasn't for competition nothing would survive

Organism in which the embryonic blastopore becomes its anus
Anika [276]

Organism in which the embryonic blastopore becomes its anus Deuterostome

<u>Explanation:</u>

The term Deuterostome refers to second mouth. The first opening which is called blastpore becomes its anus in deuterostomes. In protostomes, this first opening will be the mouth.  The other name given to these Deuterostomes enterocoelomates. It is the enterocoely from which the   coelom of  Deuterostom starts emerging and growing.  

Chordata, Echinodermata, Hemichordata are the classes of deuterostomes:. The zygote is the one that gets developed first in  protostomes and deuterostomes.Radial cleavage occurs in deuterostom in which the division of cells lies either in parallel direction or in perpendicular direction with respect to the polar axis.

Which of the following kinds of cells preform basic functions such as obtaining energy from food?
strojnjashka [21]

Plant cells, but not animal cells

Animal cells, but not plant cells

Both plant cells and animal cells

Neither animal cells nor plant cells

Answer:

Both plant cells and animal cells

Explanation:

The process where the energy locked up in food is extracted take place in both plants and animal cells.This process is called Cellular respiration.It is the process of combining inhaled and diffused oxygen in the blood with assimilated food substances (glucose,amino acids,fatty acids and glycerol) to produce energy.

In both cells it takes place in the the cytoplasm and mitochondrial.

It begins with Glycolysis, followed by Krebs's Cycle..These two steps gives certain of ATPs to these cells

.However,the largest amount of ATPs is synthesized during oxidative phosphorylation  for maximum of energy to be produced.This process involved the chemiosmosis where protons were diffused into the intramembranes by the proton pump (PMF) and diffused back into the matrix of the mitochondria to generate the electrochemical gradients.

The electrochemical gradients generate the energy for enzymes ATPase synthase needed for phosphorylation of ADP with Pi to give ATPs.

The oxygen act act the final electron acceptor.
