What is a recessive allele?
Answer:
A type of allele that when present on its own will not affect the individual. Two copies of the allele need to be present for the phenotype to be expressed.
Explanation:
Answer:
A recessive allele is a variety of genetic code that does not create a phenotype if a dominant allele is present. An allele is a specific variation of a gene, or specific segment of DNA. Different alleles produce slightly different proteins, which function in different ways.

5. Choose another stimulus from Q. 3 that will initiate a CNS motor response that will travel via the other motor division (SNS/ANS) of the peripheral nervous system (PNS) described in Q. 5. Explain your reasoning.
Answer:
1.Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else.
2.Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.
3.Sensory receptors with corresponding stimuli to which they respond.

if a sample known to be about 11,460 years old and has 400 carbon 14 Adams how many atoms are in the sample when organisms just died
Answer:
There are 1600 atoms when organism just died.
Explanation:
The statement is incorrect. The correct statement is:
If a sample known to be about 11,460 years old and has 400 carbon 14 atoms. How many atoms are in the sample when organisms just died?
The amount of atoms associated with radioactive isotopes decreases exponentially in time by means of the following formula:
[tex]n(t) = n_{o}\cdot e^{-\frac{t}{\tau} }[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial amount of atoms.
[tex]n(t)[/tex] - Current amount of atoms.
[tex]t[/tex] - Time, measured in years.
[tex]\tau[/tex] - Time constant, measured in years.
In addition, the time constant can be calculated in terms of the half-life of the radioactive isotope ([tex]t_{1/2}[/tex]), measured in years:
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
If we know that [tex]t_{1/2} = 5,730\,yr[/tex], [tex]t = 11,460\,yr[/tex] and [tex]n(11,460\,yr) = 400[/tex], then the initial amount of atoms is:
[tex]n_{o} = \frac{n(t)}{e^{-\frac{t}{\tau} }}[/tex]
[tex]\tau = \frac{5,730\,yr}{\ln 2}[/tex]
[tex]\tau \approx 8,266.643\,yr[/tex]
[tex]n_{o} = \frac{400}{e^{-\frac{11,460\,yr}{8,266.643\,yr} }}[/tex]
[tex]n_{o} \approx 1600[/tex]
There are 1600 atoms when organism just died.

What would happen if the number of grasshoppers in this food chain decreased?
A.
The amount of grass would increase.
B.
The number of lizards would increase.
C.
The amount of grass would decrease.
D.
The number of hawks would increase.
Answer:
a, the amount of grass would increase
Explanation:
if the grasshopper is the one in this diagram eating the grass, and suddenly there were fewer grasshoppers to do that, the grass would increase because more of it can grow without being eaten

Type O
Type A
Type B
Type AB
Answer:
Image result for what is The recessive gene for blood typing
Because A is dominant, that means your mother could carry a hidden O. If she does then when she gets pregnant, each child has a 50% chance of getting her dominant A and a 50% chance of getting her hidden, recessive O. If the child gets the O from mom and an O from dad, he or she will have an O blood type.

What are some environmental indicators?
When humans breed organisms, they are selecting variations that occur naturally in populations.
True or false ?
Answer:
TRUE!!!
Explanation:
Artificial selection, often known as "selective breeding," is when people choose animals or agricultural products based on desirable features, hence it is a true statement.
What is Artificial selection?Different phenotypes can be introduced into an organism via genetic changes that change gene activity or protein function.
Natural selection is the process of identifying advantageous traits in plants and animals and taking actions to improve and perpetuate those traits in subsequent generations.
If a trait is advantageous and aids an individual in surviving and reproducing, the genetic variation is more likely to be passed to the next generation.
Therefore as opposed to letting the species evolve naturally without human intervention, as in the natural selection, hence it is a true statement.

4. Compare and Contrast Which kind of plant–a sun plant or a shade plant-has a
higher rate of photosynthesis when light intensity is below 200 umol photons/mº/s?
When light intensity is above 400 umol photons/mº/s?
Answer:
Below 200 umol photons/mº/s, shade plant grow best.
Above 400 umol photons/mº/s, sun plant grow best.
Explanation:
A shade plant has a higher rate of photosynthesis when light intensity is present below 200 umol photons/mº/s because shade plants needs low light intensity for higher photosynthesis while on the other hand, a sun plant has a higher rate of photosynthesis when light intensity is above 400 umol photons/mº/s because it requires high intensity of light for photosynthesis if other factors are also present in large amount such as water and nutrients in the soil.
The diagram shows four pairs of chromosomes from the karyotype of a normal human male.
Select the pair of sex chromosomes.
Answer:
According to the karyotype image, the sex chromosomes of a normal human male are those of the last picture, where both are different.
Explanation:
The sex chromosomes are those that determine the sex in a species, as in the human being and other species X and Y. XY chromosomes determine the male sex while the XX sex pair corresponds to the female sex.
In humans, the chromosomes are grouped by pairs with the same characteristics, that is, most pairs of chromosomes are identical. The only exception is represented by the male human sex chromosomes X and Y. This difference in the sex chromosomes causes the different sex chromosomes (picture) to be called heterogametic.
