Based on this pedigree, what are the most likely genotypes of individuals I-1 and 1-2?
When entering the answer use AA, Aa, or aa.
Individual l-1 genotype=
Individual 1-2 genotype=
PLEASE HELP!
Answer:
I-1 genotype = AA or Aa
I-2 genotype = aa
Explanation:
The trait in question is autosomal and dominant. Let us assume that the trait is represented by the allele A, the alternative form would be a.
I-1 individual is affected for the disease, hence he is either true-breeding AA or heterozygous Aa.
I-2 individual is not affected for the disease, hence, she can only be aa. For an autosomal dominant trait, an individual is either affected or free from the trait. There is no chance of being a carrier. Heterozygous individuals are affected for the disease.
Therefore;
I-1 genotype = AA or Aa
I-2 genotype = aa

What is the effect of uneven heat distribution
Answer:
Unequal heating of the earth's surface causes temperature differences which cause pressure differences. Lower temperatures cause higher air pressure. Wind direction is described as where the wind is coming from. For example a northerly wind blows from the north to the south. Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.

Answer:
A. The equation for photosynthesis and cellular respiration are opposites of each other.
Explanation:
Cellular Respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O. Photosynthesis:
6CO2 + 6H2O → C6H12O6+ 6O.
Photosynthesis removes carbon dioxide from the atmosphere, and cellular respiration puts it back. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.
What will happen to a protein when the DNA codes for a different amino acid?
If a mutation occurs in the DNA let's say a point mutation only one of the base pairs will be different. The codon will be different so a different amino acid will be synthesized. Amino acids have different radicals with different functional group. Those radicals that differ from amino acid to amino acid determine the shape and function of the protein. Therefore a mutated gene will cause the synthesis of a protein with an altered shape and function. A good example is sickle cell disease. Where glutamic acid is replaced with valine and the beta chain of hemoglobin has a deformed shape and has an altered function(carries less oxygen).

Answer:
1)Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
2) The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion
3)onic bonds are important because they allow the synthesis of specific organic compounds. Scientists can manipulate ionic properties and these interactions in order to form desired products. Covalent bonds are especially important since most carbon molecules interact primarily through covalent bonding.

In 3–5 sentences, describe how carbon dioxide levels can be reduced in the atmosphere.
Answer:
Walk to places as much as possible to reduce co2 emissions from cars.
Explanation:
The levels of carbon dioxide is higher in the atmosphere than it was before because of the human activities, which is eventually leading to global warming. Carbon dioxide being one of the most important greenhouse gases is present in abundant concentrations in the atmosphere and there is a need to reduce the levels to have some relief from global warming.
Some of the ways of reducing the levels of carbon dioxide in the atmosphere are:
• Planting more trees as trees are mainly good at storing carbon by the process of photosynthesis.
• Another way to use photosynthesis to fight against climate change is the use of bio-energy with carbon capture and storage technique. It is the process of utilizing biomass as the source of energy in the power sector.
• Another way to capture carbon dioxide directly from the air is by chemically scrubbing carbon dioxide directly from the ambient air, and then storing it either in the long-lived products or underground.
Thus, there are some techniques, which can be implemented to reduce the concentration of carbon dioxide from the atmosphere.

What happens during fertilization that makes the offspring unique compared to the original cells?
Please write the answer in one sentence!
Answer:
During fertilization, two gametes from the parents —with different genetic information— join together to obtain a unique offspring, different from the parental cells that gave rise to it.
Explanation:
Gametes are the cells produced by each individual to transmit their genetic information to their offspring.
The process of producing gametes is called gametogenesis, and it is a reductive division called meisois. During meiotic division, crossing over occurs, allowing the recombination of genes, which results in genetic variability.
What makes the offspring different and unique from the parental generation is that, during fertilization, the genetic characteristics of both parents are mixed when two gametes are joined.

what's the function of adrenaline in our body
well
my account got deleted rosa
Answer:
What is the function of adrenaline?
Adrenaline triggers the body's fight-or-flight response. This reaction causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee. Adrenaline also triggers the blood vessels to contract to re-direct blood toward major muscle groups, including the heart and lungs. The body's ability to feel pain also decreases as a result of adrenaline, which is why you can continue running from or fighting danger even when injured. Adrenaline causes a noticeable increase in strength and performance, as well as heightened awareness, in stressful times. After the stress has subsided, adrenaline’s effect can last for up to an hour.
Explanation:
I think I helped
Answer:
Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye (see photo), redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels (primarily for the brain).

Explains how the atoms that make up glucose can be used to construct macromolecules
Answer:
In the dehydration synthesis reaction (attached) , two molecules of the sugar glucose (monomers) combine to form a single molecule of the sugar maltose (macromolecule)
Explanation:
Macromolecules are formed from glucose by condensation polymerization.
Macromolecules are formed by the agglomeration of small molecules called monomers. These monomers are simple molecules that can be joined together to form a larger molecule.
Glucose can serve as a monomer that is joined together to yield macromolecules such as polysaccharides. These larger molecules are formed by the process of condensation polymerization in which a water molecule is lost.

Explanation:
A neuron will generate action potentials more often when it: remains below its threshold remains below its threshold receives an excitatory input receives an excitatory input receives more excitatory than inhibitory inputs receives more excitatory than inhibitory inputs is stimulated by a neurotransmitter is stimulated by a neurotransmitter
Answer:
A neuron will generate action potentials more often when it receives more excitatory than inhibitory inputs
Explanation:
An action potential is a short term change in the electrical potential that travels along a cell. It occurs when an external stimulus is received by the cell membrane of a neuron resulting in the depolarization (a decrease in the difference in voltage between the inside and outside of the neuron) of the neuron and transmission of the action potential down the neuron.
A neuron receives both excitatory and inhibitory inputs from the many other neurons it is connected to at synaptic junctions. For an action potential to be generated in a neuron, the sum of the excitatory inputs must be greater than that of the inhibitory inputs.
