Answer:
non-random mating
Explanation:
In animals, most cases of non-random matings are related to behavior. There are three main possible ways of non-random mating:
Harem reproduction ⇒ Dominant males mate with their group of femalesDiscriminated mating ⇒ Individuals mate with genetically similar partnersSexual selection ⇒ One of the couple members chooses the other one.Sexual selection
In many bird and mammal species, and even in some fish species, one of the sexes selects the other one to mate. In general, the one that chooses is the female.
Intrasexual competition between males to get access to females plays a significant role in sexual selection. Males can develop weapons that make them greater fighters.
There is also intersexual selection, in which members of each sex apply selective pressures on the other sex, modeling their phenotype by choosing partners.
As notorious structures and behavior make males be more vulnerable to predation, sexual selection seems to operate against other types of natural selection, as it might affect males´ survival.
However, there seems to be a compensation between sexual selection and natural selection.
----------------------------------------------------------------------------------------------------------
In the exposed example, the construction of elaborated and noticeable structures is done to attract females. If females are impressed with a bower, she will choose the male that built it to mate. The better the nest is, the better the male genetic quality. So the female chooses this male because his genetic charge is significant and reflects a higher fitness for their progeny.

Answer:
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.

Is the podocyte process of the glomerular capillary wall the same as the endothelial layer?
Answer:
The podocytes have long foot processes called pedicels, for which the cells are named (podo- + -cyte). The pedicels wrap around the capillaries and leave slits between them. Blood is filtered through these slits, each known as a filtration slit or slit diaphragm or slit pore.
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.

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

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.

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

______ is a non-specific response to disease, in which the body temperature rises
Answer:
nodes
Viruses
fungi
histamine
B-cells
antigens
Fever
When a paper cut breaks the skin, it introduces outside microorganisms into the cut. The body recognizes the break in the skin. Mast cells produce histamines, which cause more blood and lymph fluid to flow to the wound. This increased flow brings phagocytic white blood cells to the area, which destroy invading organisms until the blood can clot and the skin can heal over the cut, preventing more organisms from entering the body. If a cut is too deep or too wide, special care such as stitches and antibiotics could be needed to prevent infection.
