What is a dominant allele?
A. In a heterozygous individual, the allele that determines the phenotype
B. An allele that will only have an affect on phenotype in a haploid organism; otherwise its presence will be masked
C. An allele that is very prevalent in a population
D. An allele that totally beats up on a recessive allele
E. An allele that has no noticeable affect on an organism's phenotype

Answers

Answer 1

Answer:

A. In a heterozygous individual, the allele that determines the phenotype

Explanation:

The dominant allele completely hides the expression of the recessive allele. This occurs in cases of Autosomal dominant inheritance. Even when both dominant and recessive alleles are present in the genotype, this is the heterozygous state, only the dominant trait will be expressed. Only one dominant allele is enough to express the dominant phenotype.

Which is a method that scientist used to determine the composition of earths layers

Answers

Answer:

Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.

Many factors affect rigor mortis, such as the type of clothing the person was wearing. Experts from different sciences agree that the definition of death is the end of life. Blowflies are one of the first insects to arrive at a dead body and are very useful in determining the time of death. Livor mortis refers to the color of a dead body. The only two manners of death are natural death and homicidal death. Mechanism of death describes what has occured in the body to cause death. The presence of drugs in a corpse cannot be determined by a chemical analysis of larvae found feeding on the body. In the first 12 hours, a dead body cools about 1 degree F per hour. Within minutes of a death, certain insects are attracted by the smell of the first stages of decomposition. The Body Farm is a fictional account of the work of a country coroner.

Answer:

- Many factors affect rigor mortis, such as the type of clothing the person was wearing. True

- Experts from different sciences agree that the definition of death is the end of life. True

- Blowflies are one of the first insects to arrive at a dead body and are very useful in determining the time of death. True

- Within minutes of a death, certain insects are attracted by the smell of the first stages of decomposition. True

- The Body Farm is a fictional account of the work of a country coroner. False

Explanation:

Death refers to the permanent cessation of the biological activities in an organism as a whole. Rigor mortis refers to a recognizable sign of death, which is caused by different changes in the muscles after death. Blowflies are insects that can be attracted by the smell of dead and decomposing bodies because they need to identify warm-moist and protein-rich sources to develop their eggs. Livor mortis is the red/blue/purple discoloration in the body skin after death. The manners of death can be divided into 1-accidental, 2-natural, 3-suicidal, 4-homicidal, and 5-undetermined. The mechanisms of death refer to the specific physiological derangements that can lead to the cessation of life (e.g., a heart attack), whose understanding can be essential to elucidate a criminal case. The presence of drugs in a dead body can be determined by an autopsy. The rate at which a dead body cooling depends on the relationship between the body temperature and environmental temperature (e.g, elevated body temperatures and cool environmental conditions are known to increase this value). A body farm can be defined as a research facility where the decomposition of dead bodies can be examined.

Through this process of natural selection, favorable traits are transmitted through generations.

Natural selection can lead to speciation, where one species gives rise to a new and distinctly different species. It is one of the processes that drives evolution and helps to explain the diversity of life on Earth.

What is speciation?Speciation, the formation of new and distinct species in the course of evolution. The species evolve by genetic modification.

WHAT HAPPENS TO OUR BODIES WHEN WE EXERCISE?

What is happening to her circulatory system?

When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the FOOD to produce ENERGY) more faster than they would normally, so the demand for OXYGEN and GLUCOSE is increased.

As the muscles are performing cellular RESPIRATION quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their CO2 (products of cellular respiration are CARBON DIOXIDE and WATER) so the HEART is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.

What is happening to her breathing system?

{Relates to explanation given} The requirement for oxygen is increased so now the respiratory system (in particular the LUNGS) have to work harder and faster to take in more oxygen and to exhale more CO2, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of DIFFUSION is increased.

26. false

27. true

28. false

29. false

30. true

31. true

32. false

Explanation:

The first trophic level is usually primary producers and herbivores are the primary consumers placed in the second trophic level.

There are some plants that depend on insects and small organisms for their nutrition.

Habitat is the living area of an organism it can be understood as address.

Biotic factors are the living organisms of the ecosystem while sunlight, soil, temperature are abiotic factors.

A food web is complex as it is made up of several food chains interconnected.

Normally there are only three or four trophic levels in most of the ecosystem.

Energy is not recycled in ecosystems like water or carbon.
