Answer:
256.
Explanation:
If a bacterium divides once in every half an hour, it means it will double in half an hour. Hence a number of the bacterium after half an hour will be 1×2=2. After one hour the number of bacterium will be 2×2=4. Similarly, it one and a half hours it will be 4×2=8. In two hours it will be 8×2=16 in two and half hours, it will be 16×2=32. In three hours it will be 32×2=64. In three and half hours it will be 64×2=128. Hence, in 4 (four) hours the number of bacterium will be 128×2=256.

Explanation:
Following glycolysis and the citric acid cycle, but before the electron transport chain and oxidative phosphorylation, the carbon skeleton of glucose has been broken down to CO2 with some net gain of ATP. Most of the energy from the original glucose molecule at that point in the process, however, is in the form of ____
Answer:
The correct answer is - NADH.
Explanation:
Glycolysis is a multistep part of cellular respiration in which food is broken down to give off energy in a form of ATP. In glycolysis, the end product is converted to Acetyl-CoA using the pyruvate dehydrogenase enzyme.
During the citric acid cycle and oxidative phosphorylation, there is NAD reduces and turns to NADH that moves to the mitochondria. It is converted to energy using redox reactions. Most of the energy from original glucose molecules are transported and exists in the forms of NAD to NADH.
If a mineral has a mass of 20 and a volume of 4, What is its density?
Answer:
5 g/cm²
Explanation:
Density = Mass/Volume = 20/4 = 5
Therefore, the density of the mineral is 5 g/cm². (Assuming those are the proper units).
Explanation:
d =mass/volume
d=20/4 =5

why might scientists be wary of the results of a single experiment testing a particular treatment, even when the results are peer reviewed and statistically significant
Answer:
The results may not be true for humans if the experiment used a model organism.
Explanation:
An animal model is an animal species used in research that mimics diverse human traits/features such as, for example, human response to certain diseases. Thus, animal models may provide useful information related to human developmental biology and human diseases (i.e., prevention, diagnosis, treatment, etc). However, in general, experiments involving animal models cannot be used to predict human outcomes. For example, in genetics, animal models exhibit different features to humans, including but not limited to genomes (i.e., different number and structure of chromosomes), genes, gene regulatory pathways, epigenetics gene regulatory mechanisms, etc. In consequence, animal tests may be unreliable and therefore their results cannot be directly extrapolated to human subjects.

Which type of energy do the compounds in the food we eat contain?
chemical energy
electromagnetic energy
kinetic energy
thermal energy
Answer:
Chemical Energy
Explanation:
Chemical energy is simply energy that is stored in compounds or elements, specifically in the atomic bonds that connect atoms and molecules. In food, it's a form of potential energy because it's stored away.
A frog has more offspring than can survive on available resources.
Which is this an example?
structural adaptation
overpopulation
variation in a population
artificial selection
A frog that has more offspring than can survive on available resources is an example of overpopulation.
WHAT IS OVERPOPULATION?Overpopulation is a process whereby there are more individuals of a population than the available resources.
According to this question, a frog has more offsprings than can survive on available resources. This means that there are more frogs than resources.
Therefore, frog that has more offspring than can survive on available resources is an example of overpopulation.

The graph shows the growth and reproduction in 4 different cells, A, B, C, and D, over time. Use the graph to answer questions below.
Answer: A.
Explanation:
Cells generally have a relatively short lifestyle in that they grow, divide and then die off. This is not the case with cancerous cells as those ones mutate and then multiply such that they eventually form a tumor.
Looking at the graph, most of the cells are remaining at a lower or manageable number because they are dying off. Cell A on the other hand is simply increasing in number which means that it is a cancerous cell as it is increasing its number by mutating instead of dying off like other cells would.
Consider two solutions of different sodium concentrations separated by a selectively permeable membrane. The net movement of water across the membrane will be from the area of ______ sodium concentration to the area of ______ sodium concentration.
Answer:
Consider two solutions of different sodium concentrations separated by a selectively permeable membrane. The net movement of water across the membrane will be from the area of high sodium concentration to the area of low sodium concentration
Explanation:
In this process, only water molecules can pass through the selectively permeable membrane. As the solution has different concentrations of solute, the water molecules will move from the more concentrated solution to the less concentrated solution. The process is called osmosis and is completed when both solutions have the same concentration.

case study: Explain the relationship among homeostasis, defective mitochondria, and the symptoms caused by LHON.
Answer:
Because malfunctioning mitochondria disrupts the body's equilibrium, there is a strong link between homeostasis,
defective mitochondria, and the symptoms induced by
LHON.
The condition of homeostasis in the body was also
affected by symptoms caused by Leber's hereditary optic
neuropathy (LHON).

The expression of both alleles for flower color produces a new pink. this illustrates incomplete dominance. Which of the following would be correct phenotype ratio from a cross between two heterozygous pink flowers
Answer:
C is the answer
Why does the skeleton stop growing in length?
a
Because the cartilage in the growth plate has been
replaced by bone.
b
Because there is not enough calcium and other
nutrients in the body.
Because the growth plates stop working
d Because the bones reach their maximum length
Answer:
Bones increase in length because of growth plates in the bones called epiphyses. As puberty progresses, the growth plates mature, and at the end of puberty they fuse and stop growing. ... After the growth plates fuse, there is no more increase in height, and we all then shrink gradually as we get older.
When we breathe in and out normally during rest, this is called “quiet” inspiration (and expiration). It is also called tidal volume, as it refers to the “tides”. How much air (the volume) do we typically breathe in or out during quiet breathing (in ml...you will have to convert from Liters to Milliliters)?
Answer: the amount of air that normally enters the lungs during quiet breathing, which is about 500 milliliters.

A cat with LONG HAIR (heterozygous) is a carrier of the short hair allele. Its mate has SHORT HAIR. Use a Punnett Square to determine the probability of their offspring having LONG HAIR.
Group of answer choices
25%
100%
0%
50%
75%
Answer:
50%
Explanation:
Hi there!
We are given the hair types of two cats
The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair
The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt

Woolly mammoths became extinct thousands of years ago, while other species of mammals that existed at that time still exist today. The woolly mammoths became extinct, unlike the other species, because the woolly mammoths *
1 point
produced offspring that all had identical inheritable characteristics
faced a struggle for survival
learned to migrate to new environments
had certain inheritable traits that enabled them to survive
Answer:
faced a struggle for survival
Explanation:
The woolly mammoths became extinct, unlike the other species, because the woolly mammoths faced a struggle for survival due to changing of environmental conditions. Global warming is the main cause of extinction of woolly mammoth which destroy their habitats about 10,500 years ago. The environmental conditions are not favourable for them so they faced struggle for survival which causes extinction of woolly mammoth.
