-All signal transduction cascades are shut down immediately so as to prevent the cell from mounting a response.
-Cells are unable to respond quickly to hormones, and therefore signal transduction cascades always occur over a long time.
-Cells have to be able to function alone, because they are unable to work together in a coordinated fashion.
-Cells often have to respond very quickly to changes in their internal and external environments.
_____ eat producer and consumers
Answer:
1)Consumers
2)Omnivores
Explanation:
Primary consumers are animals that eat primary producers; they are also called herbivores (plant-eaters). Secondary consumers eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants).
Omnivores eat both producers and consumers. Most people are omnivores, since they eat fruits, vegetables, and grains from plants, and also meat and dairy products from animals. Dogs, bears, and raccoons are also omnivores
Charles Darwin observed that the accumulation of gradual changes in a population leads to a new species over time.
Further Explanation:
Scientific experimentations are the logical and practical procedures that determine the efficiency of a particular claim using scientific means. Charles Darwin was the one who gives the theory of evolution that occurred by natural selection. According to Darwin, evolution was descent with modification. There is a common ancestor between the species that changed over time and became new species. Natural selection is the reason why the population grows adapted for well suited to the environment over time.
The pre-existing heritable variation in the group is the prime condition for natural selection to happen in the environment between the species. Natural selection is the process by which the well-suited organism in the population gets selected due to stress in the atmosphere thus evolving the species. In Darwin's book ‘The Origin of Species’, all these facts and information are mentioned, and the ideas of evolution and natural selection are well-reflected.

Considering the following choices;
A. to determine the gender of a fetus
B. to determine if a fetus has the correct number of chromosomes
C. to identify chromosomal defects
D. to identify the pattern of inheritance of a particular trait
Answer;
D. to identify the pattern of inheritance of a particular trait
Explanation;
The pedigree chart shows the occurrence of the phenotypes (observable characteristic) of a certain gene or genes between ancestors and predecessor.
It is created in order to find patterns of inheritance and see what the most important traits that get inherited are.
