Sharks and whales are a classic example of two different animals revealing
similar traits in the same environment. One of the similarities of these two
marine animals is their habitat. They both live in the vast range of depth in
their environment. They also have the same fin structure. They only have a
single tail for propulsion and because they are both large aquatic animals,
they both consume large volume of food, however, sharks hunt for their
food. Whales do not have this hunting tendency. Another difference of
sharks to whales is their class. Whales are mammals while sharks are fish
but they both live in the ocean. Also, whales have bones while sharks only
have cartilages.​

Answers

Answer: The similarities between shark and whales are indicative of convergent evolution.

Explanation:

Convergent evolution can be defined as the process in which the organisms are not closely related but they evolve similar traits as a result of living in a similar kind of environment or adapting traits which enable them to perform the same ecological niches.

The similarities between shark and whale is indicative of convergent evolution as the animals are not related to each other phylogenetically but they live in the same environment this they evolve same kind of traits.

The similarities between sharks and whales represent an example of convergent evolution.

Convergent evolution refers to the evolution of similar phenotypic traits in unrelated and/or distantly related species.

Convergent evolution creates analogies, i.e., different structures that may have the same function but were not present in the last common ancestor of both species.

On the other hand, divergent evolution refers to the development of dissimilar phenotypic traits in closely related species as a result of evolution by natural selection, thereby leading to speciation.

In convergent evolution, similar phenotypic features (traits) have evolved independently and repeatedly in each lineage in order to adapt to particular environmental conditions.

In conclusion, sharks and whales are an example of convergent evolution because they are distantly related species that exhibit similar phenotypic features in the same environment.

Cuboidal epithelial cells are about as wide as they are tall. ey are O Amoebas have extensions of their cell membrane. Paramecia are horizontally flattened in shape. Nerve cells are long and thin.

Answers

The ratio of surface area to volume of cells is increased in amoebas and paramecia, as they have extensions of their cell membrane and are horizontally flattened in shape, respectively. Nerve cells also contribute to an increased ratio as they are long and thin.

The surface area to volume ratio is an important factor in cell biology. It affects the cell's ability to exchange materials with its environment. When the surface area is larger compared to the volume, the cell has a higher ratio. In the case of amoebas, they have extensions of their cell membrane called pseudopodia, which increase their surface area. This allows them to engulf and absorb nutrients efficiently.

Similarly, paramecia are horizontally flattened, which also increases their surface area relative to their volume, aiding in the absorption of food particles. Nerve cells, or neurons, are long and thin to facilitate the transmission of electrical signals over long distances. This elongated shape contributes to an increased surface area-to-volume ratio.

Answers

The type of identification referred to in this scenario is known as DNA profiling. It is a method of identifying an individual by comparing their DNA with a sample from the crime scene. The DNA recovered at the crime scene is then compared to the DNA of potential suspects to determine whether there is a match. A match means that the individual is likely to be the perpetrator of the crime.

In this particular case, Shelly testifies in court that the DNA recovered at the crime scene is likely to come from the suspect because less than 0.0001% of the population has the specific genetic marker. This type of identification is called a "match probability," and it is calculated by multiplying the frequency of the genetic marker in the population by the frequency of the rest of the markers in the DNA profile.The match probability is calculated by multiplying the frequency of the genetic marker in the population by the frequency of the rest of the markers in the DNA profile. The lower the match probability, the stronger the evidence is against the suspect. Therefore, in this case, the DNA profile provides strong evidence that the suspect is the perpetrator of the crime.

DNA profiling is an important tool for law enforcement because it provides strong evidence that can be used in court to convict criminals. It is also important to note that DNA profiling can be used to exonerate innocent people who have been wrongly accused of a crime.

define observation and describe what changes occur in the brain.

Answers

Observation involves perceiving and acquiring information, triggering dynamic changes in the brain including sensory processing, neural activation, information integration, and memory formation.

Observation refers to the process of perceiving and acquiring information through the senses or by using scientific instruments. It involves actively paying attention and gathering data about a particular phenomenon, event, or object.

When we observe something, various changes occur in the brain. The primary sensory areas of the brain receive and process incoming sensory information from the environment.

For example, visual observations activate the visual cortex, auditory observations activate the auditory cortex, and so on.

As sensory information reaches the brain, neural pathways transmit signals and communicate between different regions.

These signals undergo complex processing, including pattern recognition, association, and integration with prior knowledge and memories.

This processing involves the activation and engagement of multiple brain regions, including the frontal cortex, parietal cortex, temporal cortex, and hippocampus.

Observation also triggers changes in neuronal firing rates, synaptic connections, and the release of neurotransmitters, enabling the brain to interpret and make sense of the observed information.

These changes support the formation of perceptual representations, the encoding of memory traces, and the integration of sensory information with cognitive and emotional processes.

Overall, observation leads to dynamic changes in the brain, involving sensory processing, neural activation, information integration, and memory formation, allowing us to perceive, understand, and interpret the world around us.

Answers

The two factors that account for an increase in the blood's oxygen-carrying capacity during altitude exposure are an initial decrease in plasma volume followed by an increase in erythrocytes and hemoglobin synthesis.

Red blood cells (RBCs) contain the iron-containing protein hemoglobin, which has two main purposes. In the beginning, it distributes oxygen from your lungs to the tissues all over your body. Second, it transports carbon dioxide back to the lungs so that it can be evacuated by moving it out of cells.

Both hemoglobin and RBCs are produced with the help of iron. Hemoglobin comes in a variety of forms, the two most popular being:

The most prevalent kind of hemoglobin in healthy persons is hemoglobin A (HbA).

Fetuses and newborns have hemoglobin F (HgbF), also referred to as fetal hemoglobin. HbA takes its position shortly after birth.

Is this cell haploid or diploid? How can you tell?

Answers

Answer:

The cell shown in the image is haploid, which can be affirmed by the presence of an odd number of chromosomes.

Explanation:

Haploid cells are those that have a single set of chromosomes, that is, half of the chromosomal charge (n) of an organism. These cells correspond to gametes.

Diploid cells are those with complete chromosomal charge (2n) and correspond to somatic cells.

The given description is related to the following processes:

Separate sister chromatids: Mitosis, Meiosis IIResults in diploid cells: MitosisSeparate homologous chromosomes: Meiosis I

The process of mitosis, meiosis I and meisosis II

Meiosis II and Mitosis both involve the separation of sister chromatids. In mitosis, this occurs during the anaphase stage, where spindle fibers pull apart the sister chromatids towards opposite poles of the cell. In meiosis II, sister chromatids are separated during the second round of division after the cells have already undergone meiosis I.

Mitosis results in diploid cells, this is because, during mitosis, the parent cell replicates its DNA, separates the sister chromatids, and divides the cytoplasm to produce two genetically identical daughter cells with the same number of chromosomes as the parent cell.

Meiosis I is the process that separates homologous chromosomes. During this process, the two homologous chromosomes (one from each parent) pair up and exchange genetic material in a process called crossing over. Then, they separate from each other and move towards opposite poles of the cell during anaphase I. The resulting daughter cells are haploid, containing only one chromosome from each homologous pair.
