Answer:
I believe the options are:
1) Present day species developed from earlier species
.
2) Some species die out when environmental changes occur
.
3) Complex organism develop from simple organisms over time
.
4) Change occurs according to the needs of an individual.
The answer is 4) Change occurs according to the needs of an individual.
Explanation:
Theory of Evolution:
- By definition, evolution is the process of change in an individual's/organism's characteristics over time. Evolution occurs through mutations in the genetic information or DNA of an individual.
- The theory of evolution states that all organisms change over time and are descendants of a single common ancestor. Species adapt to the changing environment by introducing variations in their DNA over millions of years. Harsh environment conditions eliminate organisms that cannot adapt to the changing environment and only the fittest survive. This is called natural selection.
- This process, occurring over millions of years, results in the formation of an entirely new species.
- The theory of evolution is contrary to the concept of Lamarckism or inheritance of acquired characters which states that characters that an organism acquires during its lifetime can be passed on to its offspring.
The answer is false. Spider bodies are made up of two segments and they have eight legs. Insects have three segments and a varying number of legs based on the species. As a predator, spiders also have multiple eyes, while insects have only two, however they may be able to rotate or otherwise be able to get a full view of their surroundings in that fashion.
Males have generally larger bones, that's the first step. Women have a wider pelvis, males have squarer chins. Males have ridged brow bones, females do not.
Hope this helped, give brainliest if it did :)
Answer:How are species related to the concept of biodiversity? Species are diverse because there are so many and they are all different. Each species is biologically diverse from another. Biodiversity leads to adaptations and natural selection.
Explanation:
Correct option A) None.
The male dwarf's father was of normal height; that is, homozygous recessive for achondroplasia. Consequently, the dwarf man of this exercise was heterozygous for the character (say Aa) because this condition is autosomal dominant.
He also has normal vision reason why he is X-NY and X-N which represents the X chromosome with the dominant N allele for normal vision. The woman is color blind and hence a homozygous recessive X-nX-n and of normal height.
Autosomal dominant helps to alleles harbored by any chromosome other than the sexual pair that show complete dominance over the recessive ones. Other diseases such as Huntington's disease, are autosomal dominant.
