What do individuals who are heterozygous for codominant traits show for a
phenotype?
Answers
Answer:
Individuals who are heterozygous for co-dominant traits show in their phenotype both traits, without mixing.
Explanation:
Codominance is a type of inheritance that does not follow the rules of Mendelian inheritance, characterized by the absence of recessive traits and two different alleles for a character that behave as dominant.
Heterozygous individuals can be observed in codominance that show two different characteristics in their phenotype, without mixing, such as cattle with spotted skin or two colored flowers.

The function of glomerulus and Bowman's capsule of the nephron is to?
(A) reabsorb water into the blood
(B) eliminate ammonia from the body
(C) reabsorb salts and amino acids.
(D) filter the blood and capture the filtrate
Answers
Answer:
The function of glomerulus and Bowman's capsule of the nephron is to filter the blood and capture the filtrate (option D).
Explanation:
The set of glomerulus and Bowman's capsule is known as the renal corpuscle, and it is the structure responsible for the filtration of blood and its uptake as urine, which passes to the renal tubular system.
The renal glomerulus is the functional unit of the kidney, and is the structure responsible for filtering the blood that arrives through the renal capillary, to eliminate the waste products present in the blood.
Bowman's capsule surrounds the glomerulus and constitutes the second component of the filtration of blood plasma, in contact with the renal tubular system.
The other options are not correct because:
A. Reabsorb water into the blood occurs in the renal tubules.
B. eliminate ammonia from the body. Ammonia is one of the waste substances, converted to urea, that is eliminated by the kidney.
C. reabsorb salts and amino acids, occurs in the renal tubules.

Answers
Answer:
parents: ww
offspring : ww
Explanation:
Purebred is the organism living beings that has their allele in their authentic form such as WW as tall and ww small and not heterozygous.
The combination of the two alleles of a gene determines the genetic trait of an organism.
Recessive alleles formed when the allele is masked by other alleles in the heterozygous condition always.
parents: ww
offspring : ww
The parents are homo-zygous ww and therefore their offspring will be homo-zygous ww.
What is purebred?A purebred organism is an individual that exhibits the same alleles for a given gene locus (w allele).
In this case, the individual is recessive homo-zygous for the trait color fruit (yellow).An individual that is dominant heterozygous will mask the expression of the recessive allele in offspring.In conclusion, in this case, the parents are homo-zygous ww and therefore their offspring will be homo-zygous ww.

Assuming 320,000 individuals develop Lyme disease each year, what is the attributable risk for the cumulative incidence of Lyme disease that comes from tick bites, if 300,000 of the new cases reported each year come from tick bites?
A. 93.75%
B. 16.00%
C. 6.67%
D. 6.25%
Answers
Answer:
The correct answer is - A. 93.75%
Explanation:
In the given question, there are total individuals with disease = 320000
in which, Disease in exposed people = 300000
the Disease in unexposed in people = 20000
Therefore, the probability of disease in exposed people would be
= Disease in exposed people/the Disease in unexposed in people
= 300000)/320000
= 0.9375 * 100
= 93.75%

Describe: Four examples of renewable resources are featured in the Energy Conversions Gizmo. These resources are produced all the time, so they will not run out. Read about each energy source, and then explain how each is produced in your own words.
Answers
Answer:
Explanations below
Explanation:
A. Wind power:
In the principle of wind power energy, the wind turbine used in the process has blades that look like propeller. When the wind turns the blade around a rotor, it spins a generator and electricity is being generated.
B. Water power (also called hydroelectricity):
The hydro power process is similar to that of the wind power. At the hydropower plants in different localities, one would notice the flow of water through a pipe, which turns the blades in the turbine, to spin a generator and electricity is being produced.
C. Solar power:
In solar power generation, solar panels are used. The required solar energy is produced when sunlight strikes the solar panels and that converts the solar power into electricity that can be used.
D. Ethanol:
Ethanol is a renewable biofuel which can be made from different things such as grasses, corn cobs and stocks, rice straw, sawdust, and wood chips. During the process, yeast is used to ferment the start and sugars in the corn and sugar cane. The starch is fermented into sugar which can also be fermented into alchohol [ethanol].
Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answers
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
Answers
Complete question:
Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. All proteins will show the same degree of divergence because different species experience the same selection pressure. All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.Answer:
3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
Explanation:
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE. All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSEAll proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUEAll proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSEAll proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.
The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.
In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.
