Birth rate: the number of individual organisms born into a population in a given year
Emigration: the movement of individuals out of a population
Death rate: the number of individual organisms that die in a population in a given year
Immigration: the movement of individuals into a population
Matching these definitions to their appropriate terms
Birth rate The number of individual organisms born into a population in a given yearEmigration: The movement of individuals out of a populationDeath rate : The number of individual organisms that die in a population in a given year. Immigration : The movement of individuals into a populationIndividual organisms enter a population either by immigration or by birth while individual organisms leave a population by either emigration or death. While the general term used to describe the movement of individuals in and out of a population is migration.
Death rate is number of deaths that occurs in a particular population over a period ( usually 1 year ) while Birth rate is the number of births that occurs in a population over a period as well.
Hence we can conclude that the terms matching each description as mentioned in the question are , Birth Rate, Emigration, Death rate and immigration.

The woman marked with a question mark is your friend. Knowing that you are taking Genetics, she comes to ask you for advice: she wants to have children, but is afraid that they will be sick with the disease. Her husband and her mother have no family history of HD. What is the probability that she is sick? What is the probability that her children will be, without knowing her own status regarding the disease?
Answers
Answer:
Explanation:
The woman with the question mark is not sure if she has the HD disease,
The mother had no history of the disease this means she is not a carrier of the disease but we are not sure of the fathers genotype.
If the father is a carrier in an homozygous dominant form(aa) and the mother does not have the disease her. gentotype is AA
A A ×aa
Aa Aa Aa Aa This means all their offspring will be Carrier of the disease because each parents contributes 50% of the gene their offspring is made of.
The probability that she is sick is 0% but she could be a carrot of the disease in an heterozygote form
If the woman who is a carrier (Aa)of the disease marries a man with no history of the disease(AA)
Aa ×AA
I
AA AA Aa Aa
The probation of their offspring being a carrier in heterozygous form is 50% while the probability of the offspring being dominant of the disease is 0%. Hence, she should not be afraid since her mother and husband who could have contributed to determining the gene of this offspring are not carriers of this gene the offspring are safe.

Which characteristic proves Lactobacillus acidophilus is from the specific kingdom Eubacteria?
Answers
Answer: It has peptidoglycan
Explanation:
The kingdom Eubacteria is the domain of prokaryotic bacteria. These are unicellular and prokaryotic organisms. Their cell membrane is made up of lipids. The cell wall is made up of peptiodoglycan which gives rigidity to the cell wall. It gives the structural strength to the bacterial cell wall, gives the strength to the bacteria, and it will counteract the osmotic pressure develop in the cytoplasm.
Lactobacillus acidophilus possess the peptidoglycan in the cell wall this establishes its relationship with kingdom Eubacteria.
In perspective, with Earth being 4,500,000,000 years old and humans being around 1,400,000 years; how long out of a 24 day time period have we as humans been here.
Answers
Answer:
Day time period have we as humans been here: 26 seconds
Explanation:
4,500,000,000 years = 1 day
1,400,000 years = X
X = 0.0003111
1 day = 86,400 seconds
0.0003111 = X
X = 26 seconds
In term of the Earth in 24-hour clock, Homo sapiens appeared on our planet only in the last 26 seconds, it means that in geologic time, humans have existed for only a brief time period and thereby it is a relatively new species.

Evolution genetics is field of science, which includes study of genetic variations that lead to evolutionary changes in organisms. As some bacteria had changed their DNA that led to development of antibiotic resistance in them.
Due to antibiotic resistance, certain bacteria, in which changes in DNA take place, become resistant against some type of antibiotics and those antibiotics are no longer effective to prevent or kill them
Thus, the correct options to be filled in the blanks are option (B) and option (C).
A channel protein specific for calcium ions was found to have a pore lined with six glutamate residues that participate in coordinating the calcium ion. What would happen to the selectivity of the pore if the Glu residues were mutated to Asp residues
Answers
Answer:
If the mutation takes place, then the shorter side chains of asp compare to Glu will affect the permeability of the transport protein to calcium ions. Specifically, the mutation will increase the sizes of the pore,which in turn decreases the selectivity for calcium ion. Hence this affect excitability of the cell.

The inheritance of the petite phenotype in Saccharomyces cerevisiae is complicated by an interaction of mitochondrial and nuclear genes. Which of the following is a false statement about petites in S. cerevisiae?
A) Segregational petites are characterized by mutations in the nuclear genome.
B) Suppressive petites are characterized by mitochondria lacking most of its DNA.
C) Neutral petites, when crossed to wild type, yield wild-type mitochondrial function.
D) The three categories of petites are segregational, neutral, and suppressive.
E) Both nuclear and cytoplasmic (mitochondrial) genes contribute to the petite phenotype in some cases.
Answers
Answer:
Option B
Explanation:
The three categories of petites are segregational, neutral, and suppressive and both nuclear and cytoplasmic (mitochondrial) genes contribute to the petite phenotype in some cases. Suppressive petites are characterized by perfoming crosses between petite and wild-type and discovering that all offspring are petite, this exhibit a "dominant" behavior which suppresses wild-type mitochondrial function and not a lack of mitochondrial function.
Why is axon covered in insulated sheath?
Answers
Answer: Myelin Sheath. The Myelin Sheath of a neuron consists of fat-containing cells that insulate the axon from electrical activity. This insulation acts to increase the rate of transmission of signals. A gap exists between each myelin sheath cell along the axon.
Explanation:. Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length. Myelin damage causes several neurological diseases, such as multiple sclerosis.

A young man who works on a ranch and lives in the log bunkhouse experiences sudden fever with muscle aches. A few days later he begins to cough and have difficulty breathing, and goes to an urgent care clinic. His blood pressure is low. A blood sample reveals a low platelet count. A Gram stain of a sputum sample shows only a few small bacteria present. Which of the following is the most likely infecting agent?
A) Bacillus anthracis
B) Hantavirus
C) Histoplasma capsulatum
D) influenza
E) Mycoplasma pneumonia
Answers
Answer:
The correct answer is: B) Hantavirus.
Explanation:
Hantavirus is an infectious disease caused by a family of viruses that exist in rodents such as rats. These viruses can either cause Hantavirus Pulmonary Syndrome (HPS), especially in the Americas; or Hemorrhagic Fever with Renal Syndrome (HFRS), which is most common in Europe and Asia.
The young man described has symptoms that match the common symptoms of Hantavirus Pulmonary Syndrome, such as fever and muscle aches (known as the 'early symptoms'), as also coughing and having difficulty breathing (known as the 'late symptoms'). Some of these symptoms can easily be confused with Influenza, but the shortness of breath and the fact that the patient has a history of working and living in a rural environment suggest Hantavirus.
HPS also produces a low platelet count and high white cell count.
Infection by Bacillus anthracis is uncommon, plus the lack of symptoms that match the disease (such as a sore throat) and the existence of muscle aches in the patient (which does not match Anthrax) can help discard this option.
Histoplasma capsulatum is a fungus that can cause lung infection when its spores are inhaled. Its symptoms are similar to HPS but with the addition of red bumps in the legs and joint pain, not muscle aches.
Mycoplasma pneumonia is a bacteria that produces pneumonia. Most of its symptoms match the patient except for the lack of a sore throat.
Colonial protists have been hypothesized to be the precursors to multicellular organisms. This hypothesis suggests that the individual unicellular members of the colony, which are initially identical, can begin to take on different functions. Then. the colony can begin to evolve into a multicellular organism. True or False
Answers
Answer:
True.
Explanation:
Protists are group of eukaryotes that are unicellular or microscopic and some times multicellular. They can live in colonies and live individually.
Some protist live in large groups called colony.
Colonial protists form larger groups of multicellular organisms. The individuals work together as large groups and perform functions to benefit each other.
most of the colonial protist are filter feeders that feed on suspended particles. Colonies enhance feeding efficiency. In choanoflagellates, coloniest has led to the evolution of metazoans

In rabbits, brown coat (B) is dominant to white coat (b). A rabbit breeder wants to know the genotype of his best looking male brown rabbit using a test cross. He has brown females and white females available to conduct his breeding experiments.
Required:
a. What should be the coat color of the female he must use in this test cross?
b. If the test cross produces seven (7) brown rabbits and one (1) white rabbit, what is the genotype of the brown male rabbit?
Answers
Answer:
a. white
b. Bb
Explanation:
A test cross usually involve crossing an individual whose zygosity is unknown with a homozygous recessive version of individual of the same species.
Brown coat (B) is dominant over white coat (b). Hence, there is no way to physically distinguish between a BB rabbit and a Bb rabbit because both of them will be brown. A bb rabbit however will be white in appearance.
A test cross would therefore involve crossing the brown male rabbit with bb (white) rabbit.
Assuming that the genotype of the brown rabbit is BB, all the progeny will be brown as shown by the cross below.
BB x bb
Bb Bb Bb Bb
In order word, assuming the genotype is Bb, some of the offspring will appear brown while some will appear white.
Bb x bb
Bb Bb bb bb
Hence, the only way the test cross would produce white offspring is if the genotype of the brown rabbit is heterozygous, Bb.

Answers
Answer:
E
Explanation:
E because....
The other options mention species that occupy niche environments and would therefore definitely not be randomly dispersed. Rushes and frogs would be found along the edges of water bodies, squirrels would be found within appropriate environments, which would be acorn tree forests and orchid plants also occupy a particular tree.
The correct option is E.
What is random dispersion?
In random dispersion, individuals are distributed randomly, without a predictable pattern. An example of random dispersion comes from dandelions and other plants that have wind-dispersed seeds.
Is random dispersion rare?In natural populations, random dispersion is rare, while clumped dispersion, which we'll focus on in this lesson, is the most common pattern. Clumped dispersion is often due to an uneven distribution of nutrients or other resources in the environment. It can also be caused by social interactions between individuals.
