How do you suppose changes in DNA lead to speciation
Answer:
The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.
Explanation:
A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.
Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

Summarize What adaptations do cephalopods have to live an active way of life?
Answer:
The answer is below
Explanation:
The adaptations that cephalopods have, to live an active way of life are numerous, some of which are:
1. Development of a SIPHON. This is a form of the adapted foot that supports survival such as swimming and directional movement.
2. A powerful and flexible arm for movement and protection
3. Using ink to form visual distractions, against predators.
Note that a good example of cephalopods are known as octopus

In a certain breed of horses, the allele for a white coat (W) is co-dominant with the allele for a brown coat (B). A white horse (WW) is crossed with a brown horse (BB)What do you predict for genotype (s) and phenotype(s) of the offspring?
Same thing with incomplete dominant
Answer:
Hope this helps have a good day <3
Explanation:
If you know the genotypes of two parents, you can predict the genotype and phenotype of their offspring. The B allele is dominant, so its phenotype is expressed, even when the b allele is present in the genotype. ... Write the second allele for the Bb horse here.

When a population is split into smaller groups, why do these groups develop different traits?
A. Traits that form in one group form evolutionary forces quickly spread through populations
B. Separating the two groups decreases the chance that the two groups will diverge
C. Gene flow is increased in the two subgroups that are formed

what does jaws of life do
Answer:
The "Jaws of Life" is a crucial tool to fire and rescue squads to save hundreds of lives every year. ... The “Jaws of Life” is used indeterminately for pretty much any type of heavy-duty tool that acts like a pair of scissors, cutter, spreader, or ram-device aimed at slicing and dicing through most automotive metals.
Explanation:
Which of the following accurately contrasts genotype and phenotype?
1. A genotype is traits that are passed on genetically, while a phenotype is traits that are developed environmentally.
2. A genotype is genetic traits that are inherited from the father, while a phenotype is traits passed from the mother.
3. A genotype is genetic traits that cannot be observed, while a phenotype refers to observable traits.
4. A genotype is traits that are not predictable, while a phenotype refers to traits that can be predicted.
Answer:
3.
Explanation:
genotypes are traits embedded in the genes that cannot be observed whilst, a phenotypes are traits that are physically displayed by the body and therefore, can be observed.
example,
genetic factor - brown colored eyes.
connotation for the gene - B
Genotype - BB.
phenotype - brown colored iris.

5 5. Normally, the temperature inside the scrotum is slightly lower than normal body temperature. What do you predict would happen if the temperature inside the scrotum were a few degrees higher than normal body temperature instead? A. Sperm would not be able to travel through the vas deferens. B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,
Answer:
C. Sperm would not be able to develop properly.
Explanation:
There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.
If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.
What is the function of "sc-rotum"?A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.
Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.
Thus, the correct answer is option C.
