QI the father
13. A father and mother claim they have been given the wrong baby at the hospital. Both parents are
blood type A. The baby they have been given is blood type o. Does the genetic evidence support
their claim?
No, the claim is not based on scientific evidence because to heterozygous parents with genotype AO may have offspring with O phenotype and therefore OO genotype (proportion 1/4 of descendence).
What is the ABO blood type?The ABO blood type is a group of phenotypes controlled by a single locus, which is based on the alleles that encode surface antigens in red blood cells. The O phenotype is due to the recessive allele, while the A allele is dominant and therefore masks the O allele in heterozygous individuals.
Therefore, we can conclude that parents having the AO genotype may produce offspring with OO genotype

This question lacks options, options are:
A) glial cell
B) interneuron
C) sensory neuron
D) motor neuron.
The correct answer is D.
Explanation:
The brain sends instructions to the muscles that control voluntary movement through nerve cells called motor neurons. The function of the motor neuron is basically to carry the information that comes from the descending pathways of the spinal cord, in order to generate an activation in the tissues of the skeletal and visceral muscles of all parts of the body. Motor neurons need the information sent to them by sensory or efferent neurons. Since in order to perform the appropriate muscle movements for the situation, our brain must receive information from the outside. By sending sensory stimulation through interoreceptors, motor neurons can regulate visceral activity, stimulating or inhibiting the activity of their effector tissues. In this way, our nervous system integrates the information from both types of neurons and allows us to move and react according to the demands and circumstances of our external context.

what is photosynthesis
Answer:
The process of making food by Green plants (autotroph) is called photosynthesis. For performing photosynthesis water, sunlight and carbon dioxide are used by the plants.
They take sunlight from sun, water from soil and carbon dioxide gas from the air present around us. The leaves have small holes called stomata which allows air to enter the plant. Leaves also contains chlorophyll in them which traps sunlight and helps in making food. Roots of plants absorbs water and Minerals from the soil and transfers them leaves through stem.
The chemical equation for the photosynthesis
is -
carbon dioxide + water -> glucose + oxygen + energy
[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
What's photosynthesis?[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
Photosynthesis is the process in which green plants derive their food (nutrients and water) through the capturing of light energy (sunlight) and using it to convert carbon dioxide (CO2) and water (H2O) into oxygen (O2) and other substances (compounds) that are rich in energy. Chlorophyll a green pigment present in plants is used in this process.

The second generation of purebred cross of -hom-ozygo us recessive organism, with a —hom-ozygous dominant organism, contain a ratio of approximately _______ expressed dominant traits to recessive traits.
A. 2:1
B. 1:1
C. 1:3
D. 3:1
Answer:
D. 3:1
Explanation:
Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.
However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

Describe three different measures that can be obtained from a single age distribution graph comparing males and females of a given population.
A single age distribution graph comparing males and females of a given population can provide a wealth of information. Three of the most important measures that can be obtained from such a graph are the population size, the age structure, and the gender ratio.
What is the way to measure the population size ?The population size can be determined by adding the total number of males and females represented in the graph. This is an important measure of the overall population size, and can be used to compare the population size of different countries or regions.
The age structure of the population can be determined by looking at the distribution of males and females across different age groups. This is an important measure of the demographic makeup of a population, and can be used to identify trends in population growth or decline.
Finally, the gender ratio of the population can be determined by comparing the number of males and females in each age group. This is an important measure of the overall gender balance in a population, and can be used to identify areas where there is a need for greater gender equality.
In conclusion, a single age distribution graph comparing males and females of a given population can provide a wealth of information. Three of the most important measures that can be obtained from such a graph are the population size, the age structure, and the gender ratio.

Answer:
1) CO₂
2) 0.2551 g
Explanation:
The balanced reactions are:
CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂
MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂
1) The gas produced is CO₂.
2) Calculate mass of CaCO₃:
(0.5236 g) (0.4230) = 0.2215 g CaCO₃
Convert to moles:
(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃
Find moles of CaCO₃:
(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂
Convert to mass:
(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂
Calculate mass of MgCO₃:
(0.5236 g) (0.5770) = 0.3021 g MgCO₃
Convert to moles:
(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃
Find moles of MgCO₃:
(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂
Convert to mass:
(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂
Total mass of CO₂:
0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂
Answer:
The average kinetic energy of the gas particles is greater in container B because its particles move faster.

The data table and the cladogram below provide information about the evolutionary history of several different species of animal. Using this information, which of the following is true of trout?
They are more closely related to salamanders than they are to birds.
They are more evolved than salamanders and lizards.
They evolved into a separate species due to the presence of lungs.
They have jaws and lungs but lack claws or nails, feathers, and mammary glands.
Answer:
They are more closely related to salamanders than they are to birds.
Explanation:
According to the data, trout are more closely related to salamanders than birds.
The first data table shows how the salamander only has one extra trait that the trout does not have (lungs).
On the other hand, birds have three extra traits that the trout doesn't have (claws/nails, feathers, and lungs).
The cladogram further shows how trout are more closely related to salamanders compared to birds.
Trout and the salamander are closer together on the cladogram, while the bird is further away. This means they are more related on the evolutionary timeline.
So, the correct answer is that They are more closely related to salamanders than they are to birds.
The statement which is true about Trout is as follows:
They are more closely related to salamanders than they are to birds.Thus, the correct option is A.
What is Cladogram?A Cladogram may be defined as a type of family tree or classification tree which is based on evolutionary relationships. It is also known as a phylogenetic tree.
Trout and the salamander are positioned closer to one another on the cladogram while the bird is being far away. The presence of lungs is marked from the salamander, so trout do not have lungs.
Trouts evolved from Hagfish but not from salamanders and lizards. Trouts only have jaws but lungs, claws or nails, feathers, and mammary glands.
Therefore, the correct option for this question is A.
