Cross a person who does not have freckles and is heterozygous for dimples with a person who has
freckles (but her mom does not) but no dimples.

2. What is the probability that these parents will have a child with freckles?
3. What is the probability that these parents will have a child with dimples and freckles?
Answers
Answer:
1. 1/2
2. 1/2
3. 1/4
Explanation:
Let the allele for freckles be A or a while that of dimples be B or b.
A person without freckles but heterozygous for dimples = aaBb
A person who has freckles (whose mother has no freckles) but no dimples = Aabb
aaBb x Aabb
Offspring
4 AaBb - freckled and dimpled
4 Aabb - freckled and non dimpled
4 aaBb - non freckled and dimpled
4 aabb - non freckled and non dimpled
1. Probability that the parents will have a dimpled child = 8/16 or 1/2
2. Probability that they will have a child with freckles = 8/16 or 1/2
3. Probability that they will have a child with freckles and dimples = 4/16 or 1/4

Explanation: The enzyme RuBisCO is an organic compound that incorporates carbon dioxide. The organic molecule is reduced in stage 2. RuBP, the enzyme that begins the cycle, is regenerated in stage 3 so that it can begin the cycle. In short, fixing six carbon atoms from CO2 requires six turns of the Calvin cycle.

what happens to the carbon and oxygen from CO2 after it has been removed from the air by the plant via photosynthesis
Answers
Answer:
Plants absorb carbon dioxide from the air and use it to feed themselves in the process called photosynthesis. The carbon dioxide, through tiny pores called stomata, reaches the leaves of the plant. ... The factory emits Oxygen, or O2, into the ambient air until the process is finished.
Explanation:
After the removal of CO2 from air by the plant, then Carbon would be absorbed by plant, Oxygen will be emitted into the air.
Photosynthesis can be regarded as the process which involve the use of sunlight , carbon dioxide and water by plant, so that to oxygen can be created as we as energy in the form of sugar.After the absorption of the CO2 from atmosphere by plant through the stomata, the plant convert it into carbon and oxygen, and the oxygen will be released to the air.Therefore, the process is called Photosynthesis

When reproducing, Robins (a species of bird) typically lay four eggs. Laying more eggs might result in malnourished chicks and laying fewer eggs might result in no viable offspring. This is an example of
Answers
Answer:
stabilizing selection
Explanation:
The illustration is an example of stabilizing selection.
Stabilizing selection is an evolutionary mechanism in which the extremes of traits are selected against, leading to an increase in the frequency of such traits in the population.
Laying too many eggs would lead to reduced fitness of the population of the bird as a result of malnutrition while laying too few eggs would lead to a reduction in the population. Reproduction needs to be optimized for maximum fitness.
There are different types of natural selection. One of them is stabilizing selection that favors the intermediate phenotype. The exposed scenario is an example of stabilizing selection.
Balancing selection, also called Stabilizing selection, decreases the frequency of individuals with extreme traits, and favors individual that exhibit medium-range characteristics, that gets to survive. Selective pressure is against h0m0zyg0tes, promoting genetic diversity. Genes expressing extreme characteristics in a h0m0zyg0sis are kept in a heter0zyg0us state, as a favorable adaptation to environmental conditions. In a graph, you will see that
→ The curve gets higher and thinner in the middle of the horizontal axe, indicating an increase in the heter0zyg0us genotype frequency.
→ The tails of the curve that coincides with h0m0zyg0us dominant and recessive genotypes frequencies will be near zero.
In the exposed example,
laying more than four eggs and less than four eggs are extreme phenotypes. laying four eggs is an intermediate favored phenotype.
The intermediate phenotype results in the species' fitness increase, so it is favored by natural selection.
Laying four eggs leads to well-nourished chicks, and all of them get to survive. Parents ensure their reproductive success.

Scientists have discovered that there are reproductive isolating mechanisms that can stop a population from interbreeding and possibly lead to the formation of a new species. What is this process called
Answers
Answer:
Polyploidy
Explanation:
The isolating mechanism that is capable of stopping a population from interbreeding, possibly leading to speciation is polyploidy.
Polyploidy is a condition in which a species of an organism will have multiple, instead of a diploid, chromosomal set as a result of an error during meiosis.
Non-disjunction during meiosis can make a gamete have a diploid number of chromosomes in the place of a haploid chromosome. A 2n gamete fusing with an n gamete will result in a triploid organism, 2n plus 2n gametes will result in a tetraploid organism, etc.
If the extra chromosomal set is from the same species, such polyploidy is termed autopolyploidy, otherwise, it is termed allopolyploidy. Having extra sets of chromosomes has the capacity to make an organism to be reproductively incompatible with normal diploid organisms of the same species. However, polyploid organisms can either self-pollinate or cross with another polyploid organism, a process that can lead to sympatric speciation.
