What are evolutionary relationships?

Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:

Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.

The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.

Therefore the correct option is B.

Which consequence is a direct result of human population growth

Answers

Answer:

One of the largest environmental effects of human population growth is the problem of Global warming.

Economic development, urbanization, energy consumption, transportation/motorization due to rapid population growth are major driving forces of air pollution in large cities.

In order to support the growing population, forests are being destroyed at an alarming rate. Deforestation occurs when humans clear forests to use the land either for agriculture or for habitation. This leads to soil erosion and the extinction of plant species. Land animals also decline in numbers and even face extinction due to human expansion that encroaches on their natural habitat and limits their ability to spread geographically.

Humans also continue to put a great demand on the natural resources of our planet. Many non-renewable resources are being depleted due to the unrestrained use of fuel and energy. Many parts of the world also suffer from a shortage of food and water.

The growth of the population puts larger demands on our already limited resources. The environment on earth is suffering from the growth of the global population. The depletion of resources and biodiversity, the production of waste, and the destroying of natural habitat are serious problems.

Answers

Answer: The arrangements and correct order of the above described genetic and behavioural adaptations includes:

A.) Camouflage: This is a survival adaptation by which an animal blends in and is hidden in its surroundings.

B.) Mimicry: This is an organism exhibiting characteristics similar to one known to be dangerous.

C.) Tropism: This is the growth or movement of an organism ( usually plant) in response to a stimulus.

D.) Venom: This is a poison secreted by animals for either defensive or offensive purposes.

E.) Mutualism: This is the interaction of two organisms where both benefits.

F.) Commensalism: This is the interaction of two organisms where one is helped and the other is neither helped nor harmed.

Explanation:

In the study of organisms and it's environment, they are able to adapt through genetic and behavioural mechanisms. Adaptation of defined as the ability of organisms to become fitted to its environment by modifying or changing its features. These features may be structural or behavioural.

STRUCTURAL ADAPTATION: Almost every part of the body of a living organism is structurally adapted to its mode of life. They are structurally adapted for the following specific functions:

--> Escape and defence: many animals use CAMOUFLAGE to remain unnoticed by potential predators. While some others are capable of producing poisonous VENOMS which may become offensive to the predators. Also many harmless organisms may possess structural behaviours that may MIMIC dangerous organisms thereby keeping their predators at arms length.

--> obtaining food: organisms needs to possess some structural features that will enable them obtain food in their environment. This usually leads to forming various feeding relationship ( which may be MUTUALISTIC or COMMENSALISM) with one another to be able to obtain food for survival.

BEHAVIOURAL ADAPTATION: Behaviour is everything an organism does in response to changes in its environment. Plants do exhibit behavioural adaptations and a typical example is the phototrophic movement of plant shoots which is a type of TROPISM.

Indicate whether each of the following statements is true of depurination (DP), deamination (DA), or pyrimidine dimer formation (DF). A given statement may be true of any, all, or none of these processes. This process is caused by spontaneous hydrolysis of a glycosidic bond. This process is induced by ultraviolet light. This can happen to guanine but not to cytosine. This can happen to thymine but not to adenine. This can happen to thymine but not to cytosine. Repair involves a DNA glycosylase. Repair involves an endonuclease. Repair involves DNA ligase. Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix. Repair depends on cleavage of both strands of the double helix.

Answers

Answer:

- This process is caused by spontaneous hydrolysis of a glycosidic bond: depurination and deamination

- This process is induced by ultraviolet light:  pyrimidine dimer formation

- This can happen to guanine but not to cytosine: depurination

- This can happen to thymine but not to adenine:  pyrimidine dimer formation

- This can happen to thymine but not to cytosine: none

- Repair involves a DNA glycosylase: deamination

- Repair involves an endonuclease: depurination, deamination and  pyrimidine dimer formation

- Repair involves DNA ligase: depurination, deamination and  pyrimidine dimer formation

-  Repair depends on the existence of separate copies of the genetic information in the two strands of the double helix: depurination, deamination and  pyrimidine dimer formation

- Repair depends on cleavage of both strands of the double helix: none

Explanation:

Depurination is the loss of purine bases (either adenine or guanine), while deamination refers to the removal of an amino group. During depurination, a β-N-glycosidic bond is cleaved by hydrolysis and a nucleic base is released (either adenine or guanine). All DNA bases may undergo deamination, except thymine (since thymine does not have an amino group). The ultraviolet (UV) radiation can cause thymine or cytosine to form dimers (e.g., pyrimidine dimers), being thymine dimers the most common lesion when DNA is exposed to UV light. Pyrimidine dimers may be repaired by different excision mechanisms, e.g., nucleotide excision repair, where the recognition of the DNA damage leads to the removal of the DNA fragment containing the lesion. DNA glycosylases are enzymes involved in the mechanism of base excision, these enzymes recognize and remove damaged bases by hydrolysis of the glycosidic bond, producing an abasic (apurinic and apyrimidinic) site. A DNA ligase enzyme covalently joins two DNA molecules by forming a phosphodiester bond, which is required during these processes.

calculate the kinetic energy of a dodgeball that has a mass of 2 kg and velocity of 4 m/s after being thrown

Answers

Answer:

Kinetic energy of dodgeball = 16 kg-m/s

Explanation:

Given:

Mass of dodgeball = 2 kg

Velocity of dodgeball = 4 m/s

Find:

Kinetic energy of dodgeball

Computation:

Kinetic energy = (1/2)(m)(v²)

Kinetic energy of dodgeball = (1/2)(Mass of dodgeball)(Velocity of dodgeball²)

Kinetic energy of dodgeball = (1/2)(2)(4²)

Kinetic energy of dodgeball = (1/2)(2)(16)

Kinetic energy of dodgeball = (32/2)

Kinetic energy of dodgeball = 16 kg-m/s

A. High levels of thyrotropin releasing hormone.
B. High levels of thyroid stimulating hormone.
C. High levels of thyroxin and triiodothyronine.
D. All of the above would tend to increase the size of the thyroid gland.
E. None of the above would tend to increase the size of the thyroid gland.

Answers

Answer:

Option A

Explanation:

Thyroid is primarily caused by lack of iodine but there are other reasons as well that lead to increased size of the thyroid gland. Some of these reason is

a) over- or underproduction of thyroid hormones

b) Nodules in the glans

Some times, due to overstimulation immune system itself attack the thyroid gland thereby producing excess thyroxine and hence causing  the thyroid to swell

Thus, Option A is correct

Answers

Answer:

Introduction, naturalization, colonization, and dispersal or spreading.

Explanation:

There are four main stages of invasion i.e. introduction, naturalization, colonization, and dispersal or spreading. In the first stage, the specie is introduced in the environment, in the second stage the specie adopt the environment, in the third stage the specie started growth and make colonies to increase its population and in the last stage the specie disperse in the environment through different means and spreading of that organism occur. The failing of adaptation to the environmental conditions leads to the failing of invasion of a specie.

Leigh's disease is a mitochondrially inherited disease with symptoms that include seizures, fatigue, impaired reflexes, breathing problems, and ataxia. The pedigree shows the presence of Leigh's disease in three generations. Individual 4 had two daughters and one son, and individual 6 had one daughter and two sons. Which of the individuals indicated are affected by Leigh's disease

Answers

About the question:

You will find the pedigree in the attached files

Answer:

individual 4 → Affected woman → Black circleindividual 5 → Affected woman or man → Black circle or squareindividual 7 → Healthy woman → Empty circleindividual 10 → Affected boy → Black Square

Explanation:      

Mitochondrial inheritance is the transmission of a disease or a trait from the maternal line.

Most of the DNI is in the nucleus, but there is also DNI in mitochondria. Sperm cells hardly transfer mitochondrial genes to the progeny, so mitochondrial DNI is mostly inherited from the maternal side. If there exists any mutation in this mitochondrial DNI, the whole progeny of the mutated woman will be affected, as they will get the mother genotype carrying the mutation. On the contrary, if an affected man is carrying a mutation in mitochondrial DNI, non of their descendants will get the disease.

Before answering the question, let us remember the pedigree symbols.

Squares represent Males/Men Circles represent Females/WomenEmpty symbols represent healthy/non-affected individualsSolid black symbols represent sick/affected individuals

In the exposed pedigree, we can see that the mother is affected by the disease (individual number 2), so all her children are also affected (individuals 4, 5, and 6) because the disease is mitochondrially inherited.

Individual 3 is a healthy man, so individual 4 must be an affected woman (Black circle). As she is the one affected, then all her children will also be affected. This couple had one boy and two girls. Individuals 8 and 9 are girls (circle), so individual 10 must be the affected boy (black square).  

On the other hand, individual 6 is an affected man (black square), son of individuals 1 and 2. This man couples with a woman, and they have all healthy children. So this woman (individual 7) must be healthy. Even though the man is affected, all their children are not because their mother (7) is not. Remember that sperm cells do not transmit the mitochondrial genes to the progeny.      

And finally, individual number 5 might be either a man or a woman. In any case, this person is also affected by Leigh's disease.
