Answer:
Convergent evolution
Explanation:
Convergent evolution can be described or explained as a process in evolution in biology. It usually occurs when two species from unrelated lines develop the same traits or features. This is believed to have happened due to the fact that they live in similar or related habitats, and have to develop solutions to the same kind of problems.
Therefore, in this case, the type of evolution between the two organisms mentioned is convergent.

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
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.
Explanation:
A variety of factors influence enzyme activity. Substances that bind to the enzyme and interfere with substrate binding or catalysis are inhibitors. Identify the type of inhibition associated with each of the descriptions and examples by classifying each statement as irreversible, competitive, or mixed inhibition.
Answer:
Explanation:
Irreversible inhibitors are inhibitors whose action are not reversible. They function by modifying enzyme in a covalent way leading to the formation of new functional group.
Irreversible inhibitors are specific to certain enzymes. Examples is inhibitor that are suicidal they makes inhibitor reactive.
Competitive inhibition are Inhibitor that are competitive in nature they resemble one of the substrate of the enzyme and are been bind to by mistake. Example is an inhibitor that resemble folate an enzyme substrate. Enzyme therefore binds to the inhibitor assuming its folate because they are identical.
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?
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.

If the results match up, then the data supports the hypothesis and thus, the hypothesis itself SUPPORTS the idea that you're studying. Afterward, discuss the experiment with your peers.
Never say that a hypothesis has been proven, because you are not proving anything, it is support.
Which species is likely to exhibit random dispersion?
A.
rushes that grow on the edges of bodies of water
B.
orchid plants that grow on the branches of a particular tree species
C.
squirrels that actively defend their territory against other squirrels
D.
frogs that live along the edges of ponds and streams
E.
sweetgum, a tree species with wind-dispersed seeds
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.

Does specific heat also mean the amount of energy needed for cooling, or is it only energy for heating?
Answer:
yes it does
here is a more clearer explanation
Explanation:
The specific heat capacity of water is 4,200 Joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4,200 J to raise the temperature of 1 kg of water by 1°C.
Some other examples of specific heat capacities are:
Material Specific heat capacity (J/kg/°C)
Brick 840
Copper 385
Lead 129
Lead will warm up and cool down fastest because it doesn’t take much energy to change its temperature. Brick will take much longer to heat up and cool down. This is why bricks are sometimes used in storage heaters as they stay warm for a long time. Most heaters are filled with oil (1,800 J/kg°C) or water (4,200 J/kg°C) as these emit a lot of energy as they cool down and, therefore, stay warm for a long time.
The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C).
Which statement best explains why fermentation occurs in mammals? It enables mammals to generate additional ATPATP in an oxygen‑rich environment. It breaks down lactic acid to generate a small amount of ATPATP under anaerobic conditions. It generates ethanol, which can be used as an alternative source of energy. It produces an acid that maintains blood pH within a narrow range. It allows glycolysis to continue under anaerobic conditions by replenishing NAD+NAD+ .
Answer:
The last option.
Explanation:
Fermentation/ Anaerobic respiration is important to supply ATP in the absence of oxygen.
In the presence of oxygen, glycolysis, Kreb's cycle and oxidative phosphorylation happen to provide about 32 ATP molecules. In its absence, only glycolysis can take place because it's the only step that doesnt need oxygen, to give a net supply of 2 ATP.
Even though glycolysis doesn't need oxygen, it needs NAD, and if the reduced NAD doesn't lose its hydrogens via oxidative phosphorylation, pyruvate (the end product of glycolysis) becomes the recipient of the hydrogen.
Pyruvate gets reduced to lactate.
The correct answer as to which best explains why fermentation occurs in mammals would be that it breaks down lactic acid to generate a small amount of ATP under anaerobic condition.
Aerobic respiration takes place in 3 steps:
Glycolysis: during which glucose is converted into pyruvate molecules with 2 ATP and 2NADH molecules produced.Citric acid cycle: during which pyruvate molecules from glycolysis are converted to CO2 with ATP, NADH, and FADH2 generatedElectron transport chain: during which the NADH and FADH2 produced in citric acid cycle are used to generate ATP.When oxygen becomes inadequate during rigorous activities in human cells, pyruvate molecules cannot proceed to the citric acid cycle due to lack of oxygen. Instead, the pyruvate molecules are converted to lactic acid through fermentation to generate 2 molecules of ATP.

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
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.
