Answer: Anything living needs to have certain conditions, if for example a group of flightless birds who are adapted for warm weather had their environment get colder each year and more extreme the surrounding plants and other animals may have a difficult time surviving and this will cause the birds to have less food. The birds also will not be accustomed to these changes and will not be able to adapt their bodies fast enough. This also makes reproduction difficult and in turn further dwindles the population.

Hope this helps!

Mashutka [201]

Vaccines are a boon in eradicating various lethal diseases and increase the immunity of the people. The development of vaccines started with the understanding the cell itself, various pathways that regulate its fate. The immunology, a branch of biological science, gave the idea of the working of the defense or the immune system of the body, and of the various specia cells that function for it. This led us to the discovery of antibodies and antigens. Vaciines are artificial means of injecting antigens into the body to generate antibodies beforehand, so that the immune system remembers producing it at the time disease causing agent strikes us.

Thus, we can summarise that STEM research or core science research has led to innovations that have shaped our lives and lifestyle to contribute to an overall good social health.

Reika [66]
  • Oxpecker birds eat parasitic ticks off the backs of zebras is an example of mutualism.
  • Mutualism is defined as a relationship between organisms in which both the individuals involved are benefitted from each other.
  • In the case of oxpecker birds and zebras, the oxpecker birds benefit as they get their food from the parasitic ticks living on the zebra and the zebras benefit as the birds help them to get rid of the parasites.
  • In this way, both these organisms are involved in a mutualistic relationship.

nlexa [21]

Answer:

Percentage of food eaten by the flock

Why is the percentage of food eaten a good number to use? Explanation:

A percentage compares the number of birds in the flock to the total number of birds in all flocks.

If the percentage is high, the flock is more successful, so the flock should grow.

If the percentage is low, the flock is struggling to eat, so the flock should shrink.

andrew11 [14]

Answer:

b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.

Explanation:

Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.
