how does concentration of tomato juice affect germination of seeds
Answer: The greater the concentration of inhibitors the less chance the substrate molecules have of binding with the active site (hence reactions slow and no germination). ... My results do show that tomato juice has a significant effect on the germination of cress seeds.
Explanation:
Over the last several decades, scientists have addressed the problem of nonrenewable natural resources such as fossil fuels. Humans are using fossil fuels at a rapid rate and scientists believe that one day we will run out of them. One alternative to fossil fuel energy is nuclear energy, specifically nuclear fission reactors. Although a reasonable solution to the fossil fuel problem, there are concerns. Identify ALL the concerns connected with the use of nuclear energy.
Answer:
operational risks and the associated safety concerns, uranium mining risks, financial and regulatory risks, unresolved waste management issues, nuclear weapons proliferation concerns, and adverse public opinion.

What are antibiotics and why are they useful?
Antibiotics are medicines that help stop infections caused by bacteria. They do this by killing the bacteria or by keeping them from copying themselves or reproducing.
Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.
Answer:
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. They may either kill or inhibit the growth of bacteria.
Uses: Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.

List ten adaptions that pinus plants display that allows them to survive a terrestrial model of life
Answer:
1) Growth Pattern
2) Conical Shape
3) Needle-shaped leaves
4) Pine needles
5) Waxy coating
6) Chemicals
7) Dark-colored needles
8) Thick bark
9) Ever growing roots
10) Small surface area of pine needles
Explanation:
Pinus plants are coniferous plants that are evergreen and long lived. They are usually found in the Northern Hemisphere and few parts of the Southern Hemisphere. Their adaptations include;
1) Growth Pattern: Pinus plants grow very closely to each other, creating a dense setting that helps to preserve warmth.
2) Conical Shape: Their conical shape helps them shed off snow and helps them produce enough food through photosynthesis by staying green all year.
3) Needle-shaped leaves: This helps reduce moisture loss.
4) Pine needles: This reduces moisture loss through transpiration.
5) Waxy coating: The waxy coating of their pine needles protect them from harsh weather like drying winds. It also protects them from sap that cause may freeze.
6) Chemicals: The chemicals present prevent wildlife from eating them.
7) Dark-colored needles: This helps them absorb heat from the sun
8) Thick bark: Protects against cold
9) Ever growing roots: Their roots do not stop growing even in winter so there is always moist and nutrients.
10) Small surface area of pine needles: Their small surface area helps in moisture retention.

Answer:
b. the carbon cycle ensures living things have a source of hydrogen
Explanation:
Bison have come close to extinction due
to uncontrolled hunting, drought, and
disease. There is now very
little
genetic variation in bison
populations.
Which of the following is a result of the
limited genetic variation in the
current bison populations compared
to earlier bison populations with
more variation?
Select one:
O a. Bison in current populations are more resistant to new
diseases.
O b. The survival rate of young bison has increased in current
populations
O c. Bison in current populations are less able to interbreed with
other species
O d. The current bison populations are less likely to be able to
adapt to environmental changes.
Answer:
D.
Explanation:
Genetic variation among species is a result of adaptation to new environments, and the lack of genetic varition among bison species means that they are less likely to adapt to different environmnetal changes. this might be due to bison staying in a particular areas to not be hunted or ridden by disease.

What do you think ecological succession is?
A male horse with a white coat is mated with a female horse with a brown coat. If coat color is a codominant trait, what would you expect the offspring to have?
All white coats
All brown coats
Mixed white and brown coats
Mixed coats of the recessive colors
Codominance is a condition observed in the inheritance of coat color in the horse. The offspring of the cross between white coat male horse and brown coat female horse is mixed white and brown cats. Thus, the correct option is C.
What is Codominance?
Codominance is a non-mendelian inheritance. It is an exception of Mendelian inheritance. It is a heterozygous condition in which both the alleles present at a gene locus are fully expressed in the phenotype of an organism. Alleles which show an independent effect are called as Codominant alleles whereas in Mendelian inheritance, one allele is dominant over the other allele which is recessive. In codominance, neither phenotype is completely dominant over other.
In the cross between a male horse with white coat and a female horse with brown coat, the coat color of the offspring produced will be a mixture of white and brown coat color.
Therefore, the correct option is C.

An important difference between a series and a parallel circuit is that a series circuit cannot have any breaks. A parallel circuit can have a break in one branch and the current can still flow through another branch.
Answer:
Yes.
Explanation:
Parallel circuit are those types of circuits in which break in one branch does not prevent the flow of current in the circuit and the current can still flow through another branch because there are more ways through which the current moves to other sources while on the other hand, series circuit refers to those circuits in which break in one branch can prevent the current flow in the circuit and the other sources can't receive current due to broken of the connection.
Diet and weight loss companies advertise how would you use skepticism to evaluate the data that these companies use in their advertisements?
Answer and Explanation:
Skepticism refers to the questioning that an individual makes about certain information, when he suspects that this information presents deceptive and lying facts. In relation to skepticism in advertisements for diets and medicines for weight loss, it is important that the individual uses skepticism to research whether the information presented in the advertisement is true. In this case, the individual must search for scientific validation of the information presented in these advertisements, assessing whether there is evidence that the advertised product is effective.
