There must be some sort of battle for existence since more people are generated than can be sustained.
Darwin and Alfred Russel Wallace, one of his scientific contemporaries, claimed that natural selection, or evolution, is the result of this process.
According to the principle of natural selection, organisms breed younger than they can withstand in their surroundings. Those who are more physically capable of surviving, maturing, and reproducing. On the other hand, those that lack this fitness either do not live long enough to reproduce or have fewer children than their counterparts. Because the "fittest" organisms—those most adapted to their environment—are the ones that reproduce most effectively and are most likely to pass on their qualities to the next generation, natural selection is frequently summed up as "survival of the fittest."
This implies that if conditions change, qualities that help people survive in it will eventuallyadapt, or develop. Naturalselection was able to describe the evolution of life with such force that it was accepted as a scientifichypothesis. Since then, biologists have seen several instances of how natural selection affects evolution. It is now understood to be one of several ways via which life develops. For instance, the phenomena of genetic drift can potentially lead to the evolution of species. In cases of genetic drift, some species unexpectedly generate more offspring. Even if those creatures may not be the best of their species, the genes they contain are passed on to the following generation.
Therefore, the idea of the battle for existence was the thought put forth by Darwin.

Answer: to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.
Explanation:
Answer:
Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization. For example, to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.
B. Rough endoplasmic reticulum
C. Golgi apparatus
D. smooth endoplasmic reticulum
the answer is both B and D endoplasmic reticulum is used for folding and transporting proteins
Based on the data table, we would expect deserts to have the greatest changes in temperatures during a 24-hour period. There is little water or vegetation containing water in desert areas. The data shows the greatest increase and decrease in temperatures to be in the cups of sand. It's B.
Answer:
Coding for the production of all cells protein
Explanation:
Chromosomes are long sequences of DNA that contain several genes and other sequences of nucleotides. In eukaryotic organisms, chromosomes are linear structures of highly stranded double-stranded DNA, normally found in the nucleus of cells, and may also be associated with proteins and RNA. In prokaryotic organisms, they have a circular or linear shape, not being present in the nucleus or associated with proteins.
In addition, chromosomes are the molecules responsible for controlling cellular processes. They do this by coding the production of all proteins in a cell.
Answer:
coding for the production of all a cell's proteins
Explanation:
The heart is a pump made of muscle and that is difficult to grow in the lab.
B)
Even if researchers build a heart, there is no guarantee that a person's body will accept it.
C)
Human hearts are not like any other animal hearts so there is not source for cells and tissues.
Eliminate
D)
The heart is made up of many different types of cells that are organized into different tissues.
