Answer:
internal
Explanation:
In order to establish the expiration date of perishable food, growth curve data must be collected. Once the microbial load is so high that it poses a hazard to human health, the food item is no longer considered safe (expired). Generally a microbial load of x50,000 bacteria/gram is considered unsafe.
Your task is to determine the microbial growth curves for MicroYo, a new brand of yogurt. The growth is determined by sampling the yogurt and growing the bacterial isolates in broth culture which is then serially diluted by a total of x10,000 and inoculated onto standard petri plates of nutrient agar. The following colony counts are measured:
Time (days) MicroYo colony count
1 1
4 1
12 2
16 4
20 7
a. 4.
b. 16.
c. 20.
d. 12.
Answer:
c. 20.
Explanation:
The answer is 20 because on 20 days, 7 colonies of Micro Yo occurs. The data of bacterial growth indicates that population of bacteria increases with the passage of time. This increase occurs due to good environmental conditions for bacteria that allows it to grow and increase their population. So we can say that the growth graph moves in the upward direction with the passage of time or number of days.

Imagine yourself as a naturalist. In your travels, you observe the toad and frog
shown here. Write two questions that might arise from these observations.
Answer:
1. What is the relationship between body shape and the habitat where they are most commonly found?
2. What is the difference between toads having a thicker skin than frogs?
Explanation:
Toads and frogs are amphibians that belong to the same family, live in lakes, rivers and wetlands and have some similar characteristics. Among their main differences are:
The skin of toads is rougher, drier and rougher. While frog skin is moist and smooth. Frogs live in humid areas, although they can go out to dry land for food. Whereas toads can survive longer on the ground away from moisture, as they have greater water control in the body. Frogs are characterized by long limbs that favor long hopping and swimming. On the other hand, toads have shorter legs. Toads tend to be more rounded, muscular and stocky. Frogs tend to be more slender.Most toads are poisonous. In contrast in frogs, not all species are poisonous.
Given these observations, two questions that may arise could be:
1. What is the relationship between body shape and the habitat where they are most commonly found? This is that frogs have longer legs which helps them to swim and that is why they are more commonly found in water. While toads have shorter legs that even allow them to burrow into the ground, they can survive longer on land.
2. What is the difference between toads having a thicker skin than frogs? Toads have thicker and more impermeable skin than frogs, which allows them to live in drier places. Also, the blood of the toad is of higher osmotic concentration than water.
Answer: what is the difference between the body’s and the habitat they are in?
Explanation:both have similar habitats and look the same
The pedigree diagram shows how a recessive trait is inherited in a family. The red circle shows a person with the trait.

In cells, driving an unfavorable process by coupling it to a favorable one requires the availability of compounds that can undergo reactions with large negative free energy changes. Such substances can be thought of as energy transducers in the cell. Explain the reason that many of these energy-transducing compounds are organic phosphates such as ATP.
Explanation:
In the final stage of respiration, ATP is formed through a series of electron transfer reactions within the cytoplasmic membrane that drive the oxidative phosphorylation of ADP to ATP. Bacteria use various flavins, cytochrome, and non-heme iron components as well as multiple cytochrome oxidases for this process.

How does that landslide change the
ecosystem? Include examples of competition
of food, water, shelter, and life.
Answer:
The correct answer is - Increase in competition. destroy habitat, water and resources scarcity, and reduction in population.
Explanation:
Landslides are the movement of debris, rock, or land. It can be lethal and affects the ecosystem in various ways. The major effect on the ecosystem is destroying the resources and habitat of the organisms and even pollute water streams and water bodies with excess debris and sediment. It affects water quality and aquatic organism's habitat.
It destroys a large part of habitat such as forest, shelter and affects the life on the particular ecosystem. The reduction of the plants and vegetation leads to a reduction in food which increases the competition.

Answer:
In times of severe drought, the average beak depth increases to handle the limited food supply. With only tough seeds to eat, a large beak is needed. Due to a large beak being needed, the small and medium beaked finches died out after 5 years as they were unable to adapt to these new conditions.

Diabetes is a disease characterized by the inability to break down sugars. Often a person with diabetes has a defective DNA sequence that messes up the code for making insulin. Suppose a person has a mutation in their DNA, and the first triplet for the gene encoding insulin is CCC (instead of CCA). Determine what amino acid the new DNA triplet codes
Answer:
The new CCC codon codes for proline, while the original CCA codon also encodes for proline
Explanation:
A synonymous substitution is a mutation produced by the substitution of one nucleotide for another in an exonic gene segment which doesn't modify the original amino acid in the protein sequence. Moreover, a silent mutation is any alteration in the nucleotide sequence that does not produce an observable effect on the organism's phenotype. The example above describes a synonymous substitution because the new codon (CCC) also codes for the same proline amino acid as the original non-mutated codon, thereby the resulting protein sequence remains unchanged. Consequently, in this case, mutations associated with diabetes are located at other gene regions. The genetic code is degenerate because different codons can code for the same amino acid.

Sally is a 41 year old female with a history of unsuccessful weight loss attempts. In the past, Sally has tried "almost every diet known to man" and now wants to lose "at least fifty pounds" and "stop fighting with myself". Sally lives alone, and works as an accountant. Her hobbies include reading, spending time with her cat, and shopping. She describes her life as "pretty isolated" and rates her happiness at a 4 out of 10. She explains that when trying to change her behavior, she usually "falls off the bandwagon after a few days", and describes herself as "stuck". She has no history of injuries or preclusions to exercise and has recently had a clean physical exam, with the exception of needing to lose weight.
Describe what approach you would take with Sally to help her change her behavior?
Answer:
the approach has been described below
Explanation:
I will have to use motivation as a way of enhancing change in the life of Sally. From this question, she seems to be a lonely lady, with low self-esteem and no physical activity. The first thing I would do is to help to get her out of monotony by motivating her.
Once motivated, I would help plan her diet and add combinations of physical activities. These activities may include walking and running. With time an expert would take over her physical training.
She has to make time for other activities such as yoga or community work. The purpose for this is so she can meet and connect with other people, this would give her a sense of belonging. And would help boost her self image.
In conclusion, Sally needs a combination of physical and emotional therapy in order to change her lifestyle.

If mitosis happens in our gonad cells that produce egg or sperm. How will it impact the progeny's chromosome number? Emphasize also the point why is meiosis so very important.
Who understand this
Explanation:
If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
Which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building?
•
conduction
convection
radiation
reflection
Answer:
I belive it is Convection
Explanation:
It is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

Can two species share the same niche? Why or why not?
Answer:
No
Explanation:
Because they'd be fighting for the exact same resources
Answer:
The competitive exclusion principle tells us that two species can't have exactly the same niche in a habitat and stably coexist. That's because species with identical niches also have identical needs, which means they would compete for precisely the same resources.

4. Owls have large eyes that enable it to see well at night. Both the hawk and the owl hunt similar things: small rodents or snakes. How do the hawk and the owl avoid competing with each other?
Answer:
They avoid competing because owls are nocturnal as hawks are not. So that means owls are asleep in the morning while hawks are hunting, and hawks are asleep at night while owls are hunting.
Explanation:
Several genes in humans in addition to the ABO gene (I) give rise to recognizable antigens on the surface of the red blood cells. The Rh marker is determined by positive (R) and negative alleles (r) of gene R, where R is completely dominant to r. The presence of M and N surface markers are controlled by two codominant alleles of gene L (LM and LN). For each mother-child pair, choose the father of the child from among the males in the right column. (Assume that all mothers and fathers are HH.)
