Answer:
The correct answer is No.
Explanation:
Measuring the volume change after placing:
In a hypertonic solution - solvent moves outside of the cell and the cell shrinks, the change in volume of solvent would be very minute to observe or measure as the RBCs are very small cells.
in a hypotonic solution - the change in the solvent or solute or overall solution is very less and will be very insignificant to come to any result. The water volume change would be difficult to measure.

Explanation:
Bacteria divide by a process called binary fission where one bacterial cell will replicate its
DNA as the cell elongates, then the cell will divide into 2 identical daughter cells. Assuming
favorable conditions, bacteria divide every 20 minutes. If one bacterial cell replicated
according to this condition, how many bacterial cells would one expect to find at the end of
two hours and 20 minutes (140 minutes)?
lol
Answer:
The usual method of prokaryote cell division is termed binary fission. The prokaryotic chromosome is a single DNA molecule that first replicates, then attaches each copy to a different part of the cell membrane. When the cell begins to pull apart, the replicate and original chromosomes are separated.

Following the cell division of a eukaryotic cell, the two daughter cells end up with the wrong number of chromosomes. One has one too many chromosomes and the other has one too few. During which phase of mitosis did this error likely occur?
The error most likely occured during the anaphase of mitosis.
MITOSIS:
Mitosis is a type of cell division in which two genetically identical cells result from a single parent cell. Mitotic process occurs in various stages namely: interphase, prophase, metaphase, anaphase and telophase. The chromosomes separate i.e. are pulled apart equally into each daughter cells at the ANAPHASE STAGE. Hence, an error in cell division in which one daughter cell has one too many chromosomes and the other has one too few chromosomes occured specifically in the ANAPHASE STAGE.Learn more at: https://brainly.com/question/3327479?referrer=searchResults
This type of inheritance pattern shows BOTH traits in possible offspringand is not a blending or intermediate
phenotype.
O a. incomplete dominance
O b. dominant pattern inheritance
O c. complete dominance pattern inheritance
O d. codominance
Answer:
The correct answer is - d. codominance.
Explanation:
Complete dominance is the pattern of inheritance where one allele masked the other allele completely in a heterozygous condition. Incomplete dominance is a pattern of inheritance where both the alleles blend or form intermediate phenotype in heterozygous condition.
The codominance pattern of inheritance is similar to the incomplete dominance but instead of making a blend of both alleles, it expresses both alleles together in patches or pattern.
The type of inheritance pattern that shows BOTH traits in offspring and is not a blending or intermediate phenotype is CODOMINANCE.
In genetics, codominance refers to the phenomenon by which both parent phenotypes for a given trait are simultaneously expressed together in the offspring.
Conversely, incomplete dominance occurs when the phenotypes of the two parents are mixed in the offspring in order to create a new intermediate phenotype.
Finally, complete dominance refers to the inheritance pattern by which a dominant allele completely masks the expression of the recessive allele in offspring.
In conclusion, the type of inheritance pattern that shows BOTH traits in possible offspring and is not a blending or intermediate phenotype is CODOMINANCE.

HypermethylationG. Are expressed H. protein-coding genes______promoters will lead to reduced expression of the correspondent genes. Some genes such as____and_____need to be expressed. When they______, this can lead to cancer.
Answer:
Hypermethylation of___ promoters will lead to reduced expression of the correspondent genes. Some genes such as Cell Cycle stop genes _and__DNA repair genes_need to be expressed. When they__are not expressed_, this can lead to cancer.
Explanation:
Oncogenes are genes that may trigger cancer, where they are generally overexpressed (i.e., expressed at high levels). Although there are well-documented exceptions to this rule, DNA methylation generally represses gene expression by preventing the binding of transcription factors to promoters. It is known that the hypermethylation of tumor suppressor genes including, for example, cell cycle stop genes and DNA repair genes, may lead to cancer. Similarly, hypomethylation of oncogenes such as, for example, Cyclin D1 (a cyclin-dependent kinase involved in cell cycle progression), may also contribute to carcinogenesis.

Holding your breath can only last a limited amount of time because you feel the need to start breathing again. The stimulus that drives this response is mediated by _______________.
A- Decrease in circulating O2 in blood
B- Increase in circulating O2 in blood
C- Decrease in circulating CO2 in blood.
D- Increase in circulating CO2 in blood
Answer: A - Decrease in circulating O2 in blood
Explanation:
To survive, the body needs to supply oxygen to the various cells so that they may use it for respiration. It uses blood as a conduit and acquires oxygen through breathing.
If a person stops breathing, it means that the cells will not be getting enough of the oxygen required to respire. When the oxygen levels get too low, the body will force the breathing to replenish oxygen and keep respiring.

What are other factors that could affect reaction time? Research and describe how the peripheral nervous system and the central nervous system work together in reacting to stimuli?
Answer:
Many factors have been shown to affect reaction times, including age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual. Sensory neurons convert a stimulus into an electro-chemical signal, which flows the length of the
sensory neuron(s), then through a neuron or neurons of the central nervous system, and then
through the length of the motor neuron(s). Generally, motor neurons will cause a muscle to
contract or a gland to secrete a substance. Reactions that involve only the receptor, the spinal
cord, and the effector, are faster than those which involve processing in the brain. Reactions
which only travel to, through, and from the spinal cord are often called spinal reflexes or cordmediated reflexes; withdrawing one’s hand from a hot stove is an example of such a reflex.
In ‘simple reaction time’ experiments, there is only one stimulus and one response. Catching a
dropped stick, or hitting a button when a light changes are examples.
In ‘recognition reaction time’ experiments, there are symbols to respond to and symbols to be
ignored. There is still only one correct stimulus and one response. An example would be
catching a dropped stick with a word cue, while having to ignore other spoken words which are
not cues.
In ‘choice reaction time’ experiments, there are multiple stimuli and multiple responses. The
reaction must correspond to the correct stimulus. Typing a letter which matches a printed letter
prompt is an example of this type of experiment.

A key prediction/implication of evolutionary theory is that:
Answer:
-all species change gradually over time.
Explanation:
Mutation often results from cell replication and division. These occur as small, random, errors within the genetic code that become more common or stable within a population over time as traits.
As organisms live within varying niches, environmental changes may render some genetic traits obsolete. However, others may become more beneficial as an adaptation. These adaptations, which make an organism and its offspring suited to a niche, and more likely to survive and reproduce become inherited- this process is called evolution.

Algae are photosynthetic protests that act similar to plants since they can make food for themselves es. What factors must be present for algae to grow densely or in abundance?
Answer:
Carbon dioxide, water, sunlight.
Explanation:
Photosynthesis uses the energy in sunlight to drive the reactions that produce glucose. These reactions are necessary for the algae to produce food, continue to survive, and grow.
As well as sunlight, photosynthesis requires carbon dioxide and water as reactants. The reaction produces glucose and releases oxygen as a byproduct.
The algae need an adequate supply of all of these reactants to grow in abundance.
Various hormones and factors (signal molecules) both influence and encourage mitosis in vertebrate animals. What processes might these signal molecules elicit in cells, and why might this signaling be important to homeostasis for an animal?
Answer:
Mechanisms enabling one cell to influence the behavior of another almost certainly existed in the world of unicellular organisms long before multicellular organisms appeared on Earth. Evidence comes from studies of present-day unicellular eucaryotes such as yeasts. Although these cells normally lead independent lives, they can communicate and influence one another's behavior in preparation for sexual mating. In the budding yeast Saccharomyces cerevisiae, for example, when a haploid individual is ready to mate, it secretes a peptide mating factor that signals cells of the opposite mating type to stop proliferating and prepare to mate (Figure 15-2). The subsequent fusion of two haploid cells of opposite mating types produces a diploid cell, which can then undergo meiosis and sporulate, generating haploid cells with new assortments of genes.

Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall. After this sudden displacement of water, gravity acts to balance the water levels back, resulting in a tsunami.
Question 2 options:
True
False
Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall this is a correct statement.
What is tsunamis?A tsunami may initially look like a swiftly rising tide rather than a breaking wave. Due to this, it is frequently referred to as a tidal wave, despite the fact that the scientific community does not support this usage because it could create the mistaken impression that tides and tsunamis are causally related.
Tsunamis often consist of a sequence of waves that arrive in a "wave train" and have durations varying from minutes to hours. Large events have the potential to produce waves with tens of meters of height.
Although tsunamis only affect coastal areas, their destructive force can be immense and they can have a significant impact on entire on earth.
Therefore, Tsunamis begin when some kind of trigger, such as an earthquake, landslide, or volcano, causes a large part of the surface of the water to rise or fall this is a correct statement.
