What kind of genetic disorder is represented in the pedigree?
Answer:
an autosomal recessive disorder
Explanation:
Autosomal recessive disorders are inherited diseases caused by the presence of two copies (alleles) of an abnormal gene, thereby only homo-zygous recessive individuals are affected by this type of disease. In consequence, although both parents don't express the disease, they can be carriers and pass this recessive disorder to their offspring who express the disease. In this case, the pedigree shows that heterozygous parents are not affected but they are carriers of the recessive allele for this disease, thereby some offspring express the trait. The black circle (female) and the black square (male) indicate affected individuals in the pedigree chart. Since both parents are heterozygous, 1/4 (25%) of all offspring would be expected to have the autosomal recessive disorder.
How are contaminants magnified up the food chain?
Answer:
Biomagnification also called food web magnification or food web accumulation is the progressive increase in the concentration of contaminants in organisms as the trophic level increases. These unexpectedly large concentrations are the result of DDT biomagnification up the food web.
Explanation:
Which type of tumor, benign or malignant, causes more damage to the body?
Answer:
A malignant tumor is more dangerous because it can grow quickly. It may grow into or spread to other parts of the brain or to the spinal cord.
Explanation:
Tumors can be benign (noncancerous) or malignant (cancerous). Benign tumors tend to grow slowly and do not spread. Malignant tumors can grow rapidly, invade and destroy nearby normal tissues, and spread throughout the body.

Rebecca’s family uses their house’s heating system to stay warm in the winter. How do they know when their system is at equilibrium?
A. The house temperature balances the set temperature and the system shuts off.
B. The house temperature is changing and the system is rapidly changing from on to off then back again.
C. The house temperature is lower than the set temperature and heat is on.
D. The house temperature is higher than the set temperature and the cooling is on.
Thank you.
Answer: A
Explanation:
Answer:
A. The house temperature balances the set temperature and the system shuts off.
Explanation:
Equilibrium is a state in which the competing factors of a system are in balance. In the case of the heating system, the house temperature and set temperature would be the same and the system would turn off.

When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. What is this practice called?
Variation
Adaptation
Natural selection
Artificial selection
Answer:
artificial selection
Explanation:
When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. The practice is called Artificial selection.
What is Artificial selection?Artificial selection is the process of identifying desirable qualities in plants and animals and then taking action to strengthen and pass those traits on to succeeding generations.
Artificial selection operates in a similar manner to natural selection, with the exception that in natural selection, these judgments are made by nature without human intervention.
Natural selection, sometimes summed up by the adage "survival of the fittest," is predicated on the following ideas: In the natural world, organisms give birth to more children than they can keep alive and reproduce.
Therefore, When farmers want two desirable traits in cows, they often breed individuals that have those traits in the hopes that the offspring will have both desirable traits. The practice is called Artificial selection.

List the levels of organization of that makeup an organism, starting with an atom and ending with an organism.
Atom, molecule, organelle, cell, tissue, organ, organ system, organism
The levels of organization that makeup an organism are the degrees of increase in complexity of structures, from the atomic level to more complex ones. In this sense, the levels of organization of an organism are:
1. Atom
2. Molecule
3. Macromolecules
4. Cells
5. Tissue
6. Organs
7. System of organs or apparatus
8. Organism
The atom is the smallest fundamental unit of matter, it is made up of subatomic particles: protons, electrons, and neutrons.
Different combinations of similar or different atoms form molecules.
Macromolecules are large molecules, generally formed by polymerization of smaller units called monomers.
The cell is the essential structure for life, which is made up of different combinations of molecules.
Tissues are structures made up of combinations of cells.
Organs are a collection of tissues in a structure with a common function.
Organ systems is the system where organs are related to fulfill a systemic function.
An organism is an individual multicellular living being that has an independent existence, made up of a variety of systems.
Therefore, we can conclude the levels of organization of that makeup an organism are atoms, molecules, Macromolecules, cells, tissues, organs, organ systems and ending with an organism.

When you lean against the wall, there is an equal and opposite force exerted on you by the wall.
O Newton's First Law
O Newton's Second Law
O Newton's Third Law
Answer:
Newton's 3rd law
Explanation:
When you lean against the wall, there is a contact made between you and the wall, so whenever contact comes into play, normal reaction force always exist, so that makes up action-reaction pair.. so it's Newton's third law!!

1. Make a prediction of how self-control impacted the GPA of the students in the study and explain WHY you think so. 2. Then answer one of these questions: What helps you control yourself?
What makes you feel out of control?
What makes you fearful?
What helps you feel calm?
Answer:
Explanation:
1. A study conducted by Tangney, Baumeister, and Boone, indicates that self-control not only could predict GPA, but also better adjustment, better interpersonal, secure attachment, and more optimal emotional responses.
2. Start by slowing your thinking down. Take slow deep breaths. Take yourself to a quiet place. By learning how to recognize our inner emotions and thoughts, name them, and let them pass through us, we can practice more self-control, which also helps build greater agency.
11. How has our misguided, or inappropriate, use of antibiotics led to the development of organisms like
MRSA and VRSA?
Answer:
1. use of the wrong antibiotic
2. use of insufficient concentration of the right antibiotic
Explanation:
MRSA means Methicillin-resistant staphylococcus aureus
VRSA means Vancomycin-resistant Staphylococcus aureus
These are resistant forms of the bacteria Staphylococcus aureus to the antibiotics mentioned.
Bacterial resistance to antibiotics occurs when bacteria develop mechanisms that protect them against the effects of previously effective antibiotics.
Misguided and inappropriate use of antibiotics results in resistance, and they mainly occur as a result of two activities:
1. Use of wrong antibiotics: antibiotics are chosen using a microbiological technique called 'sensitivity testing', to determine which antibiotic is effective against a bacterium. However, when antibiotics are taken without proper sensitivity testing, the bacteria develop resistance against such antibiotics.
2. Use of inadequate concentration of the right antibiotic: This involves using less than the minimum inhibitory of minimum bactericidal concentration of an antibiotic against a bacteria. In this case, the organism has ample time to evolve in the presence of the antibiotic, hence the occurrence of resistance.

Answer:

Explanation:
Use the original DNA sequence above to write an example of each of the following types of mutations: insertion, substitution, and frameshift.
For example: GGATACCTAGGTAAT
Insertion: GGATGACCTAGGTAAT
a nucleotide that was not present before is inserted into the original sequence
Substitution: CGATACCTAGGTAAT
the first nucleotide was substituted in for another (C for G)
Frameshift (basically a insertion or deletion, we'll try deletion here): GATACCTAGGTAAT
the first nucleotide was deleted, causing the reading frame to be shifted (instead of GGA as the first codon, we have GAT)
