I think it will change, because over the years they have found different ways to show the atom, and different discoveries. We always have a new chance to discover something new about the atom.
Answer:
The correct answer would be C) It increases survival for cuckoos, but decreases survival of the other birds.
The host chicks often face lots of competition from the cuckoo chicks in terms of food as well as space. It makes it difficult for the host chicks to survive.
It has also been found that cuckoo chicks beg to be fed more intensely due to which host chick die due to starvation.
In addition, in some species of cuckoo, cuckoo chicks remove host eggs from the nest within few days of hatching.

Euglena is a large genus of unicellular protists: they have both plant and animal characteristics. All live in water, and move by means of a flagellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants.
Answer:
Explanation:
Natural selection only acts on the population's heritable traits: selecting for beneficial alleles and thus increasing their frequency in the population, while selecting against deleterious alleles and thereby decreasing their frequency—a process known as adaptive evolution.
Mutations are like genetic mutations. Say a bird species may usually have a orange beak but one bird was born with blue, that’s a mutation.
Adaptations are things you adapt to like plant species have adapted over the year to receive less and less water to live.
Natural selection is basically ‘killing off’ the weaker ones. Say a bird species has broad wings but mutations happened over time leading them to have small wings that do not allow flight, they may eventually all die off due to that. Extinction is if al those birds were to die off from that mutation.
