Final answer:

Three imperfections of the vertebrate eye include the presence of a blind spot, variability in visual acuity and sensitivity among different species, and astigmatism as a vision defect.

Explanation:

Three imperfections of the vertebrate eye are the presence of a blind spot, variability in visual acuity and sensitivity among different species, and the occurrence of astigmatism as a vision defect.

The blind spot is caused by the positioning of nerve cells and blood vessels in front of the light-sensitive cells of the retina. This design flaw is a result of the evolutionary path that led to the vertebrate eye.

Visual acuity and sensitivity differ among species based on their ecological niches. For example, eagles have a higher visual acuity than humans due to their specialized life-style.

Astigmatism is an unevenness or asymmetry in the focus of the eye, resulting in elongated or blurry images. It can be caused by irregularities in the cornea, lens, or retina.

Answer: C) gas; liquid

Explanation: There are three states of matter: solid, liquid and gas. Water can exist in these three states. Water is a liquid but when heat energy is applied to it, the temperature rises until it reaches its boiling point where it begins to boil and as water boils, it changes to gaseous state i.e., it turns to vapor. When heat is removed, the temperature decreases and the vapor condenses to liquid and if the heat removal continues, the temperature continues to drop until it reaches its freezing temperature (0°C) where it changes from the liquid to ice (the solid state).

Answer:

Exposure to the disease

Explanation:

Before vaccines,  the only way to develop immunity to a disease was to be exposed to the disease-causing pathogen without being harmed by it. A good example of this is smallpox, which was also the first vaccine developed. It was noticed that milk maids weren't catching and dying from small pox like everyone else, because they had been exposed to cowpox. This premise was used to create the first vaccine.

Vaccines give you immunity by injecting you with a small amount of a (usually inactive) pathogen. inside your body.  This means your immune system produces antibodies against it. Similar to what happened with the milkmaids.

Explanation:

Answer:

The correct option is A)  It is not written by an authority

Explanation:

In the English language, credibility can be described as the quality of an object to be reliable or trusted.

A piece of written work which does not mention the name of the writer may be considered to be not reliable and trustworthy. Hence, the correct option is A.

Other options, like option D, is not correct because a peer- reviewed journal carries authentic information as the work has been rechecked by different people who have expertise on the subject.

MM'Ss  or MMSs are the possible genotype of Hermione's parents.

Darwin's finches

Explanation:

Darwin's finches are the 13 different species of bird which he observed on the Galapagos island during his voyage on the H.M.S Beagle.  The study of these finches helped Darwin to propose the phenomenon of natural selection. According to Darwin, the 13 different types of finches arose because of the different modes of nutrition for the birds located on each island. Through natural selection, those traits evolved which made the species more adaptable to live on the particular island

Answer

Tempature

Explanation:

Answer: D) temperature

Explanation: Kinetic energy is the energy of a moving particle or body. When the temperature of a substance is increased, the particles of the substances gain kinetic energy, and when the temperature decreases the kinetic energy decreases. When the temperature of a substance is zero, the kinetic energy of the particles is zero. For example, when heat is applied to water, its temperature increases, and the kinetic energy of the particles begin to increase. If the heat persists, the temperature continues to increase and kinetic energy of the water particles continues to increase and the particles begin to move in a random manner, colliding with one another and the walls of their container until a point where the water begins to boil. When the heat is removed, the temperature decreases and the kinetic energy of the water particles decreases until the water cools.

Lack of interaction with social and cultural environments transforms people into members of society is a false statement.

Explanation:

Socialization which involves social interaction of people with each other will help transform themselves into active members of society.

The way we interact and project ourselves to our friends, relatives, parents, teachers, colleagues, neighbors and others grades our socialization process.

Knowing about the social and cultural environment of society and interacting with others based on that knowledge will help an individual to interact closely with other people and hence will transform to being a member of that society.

People who are less or unsocialized, self-interested shows a lack of interest in knowing the social and cultural environment of others and hence would not be successful in socializing.

Socialization process helps to change the status of an individual from “I” to “me”. The “me” part understands the values, expectations, and rules of a society and hence interacts socially to become a member of society.

The difference between the human hand and that of the cat are uses of the appendage and the size and number of certain bones. The human arm is used for a variety of functions while the lizard's and the cat's are used for walking an climbing,

Final answer:

The human arm and the cat's forelimb share a similar bone structure with a humerus, radius, and ulna, pointing to a common evolutionary ancestor. Their functions differ, with human arms optimized for manipulation and cat forelimbs for locomotion.

Explanation:

Comparing the forelimbs of a cat to the human arm reveals significant anatomical similarities. Both contain a single upper bone known as the humerus, and two lower bones, the radius and ulna. Additionally, both limbs include carpals (wrist bones), metacarpals (hand bones in humans, paw bones in cats), and phalanges (fingers in humans, toes in cats). These structural similarities point to a common evolutionary ancestor. However, the functions of these limbs differ; the human arm is adapted primarily for manipulation and complex movements, while the cat's forelimb is adapted for walking, running, and climbing.

The bones of mammals like humans, cats, and whales all follow this basic design, indicating homologous structures that have evolved over time to perform different functions in different species. For example, the human arm is used for throwing, whereas the cat's forelimb is for locomotion, and the whale's flipper is for swimming. The construction of these body parts is controlled by Hox cluster genes, further underscoring their shared biological heritage.

Answer:

Meiosis is known as the reduction division. It produces four haploid (n) gametes containing only one chromatid from each chromosome. Therefore, at the end of meiosis 2, the number of chromosomes is half that of the original cell.

Explanation:

Following is a summary of the events of meiosis:

Interphase:

Prepares the cell for division. Duplication of DNA, duplication of centrioles occurs and the cell grows in size. At this stage the cell is diploid (2n).

Prophase 1:

First stage of Meiosis 1.The centrioles move to the poles of the cell, the nuclear membrane disintegrates, homologous chromosomes pair up (in the form of tetrad), form a chiasmata and then exchange segments of chromosomes with each other. This process is called crossing over.

Metaphase 1:

Involves the arrangement of the crossed over, homologous chromosomes on the metaphase plate which is sort of like a web of spindle fibers that originates from the centrioles.

Anaphase 1:

The tetrads arranged on the metaphase plate are pulled apart by the spindle fibers. This is the result of tension that build up in the spindle fibers as they grow towards opposite poles.

Telophase 1:

The last stage of meiosis 1. Involves the arrival of the chromosomes at the poles, the nuclear membrane starts to form and the chromosomes start decondensing. Telophase 1 yields 2 daughter cells with half the number of chromosomes as that in the parent cell.

Meiosis 2:

Meiosis 2 is exactly similar to mitosis. The only difference is that the haploid cells entering meiosis 2 do not duplicate their DNA. Meiosis 2 just involves the separation of the sister chromatids of homologous chromosomes.

As mentioned above, interphase does not occur before meiosis 2.

Prophase 2 involves the disintegration of nuclear envelope, centrosomes start moving to the poles.

Metaphase 2 arranges the chromosomes on metaphase plate.

Anaphase 2 separates the sister chromatids from the chromosomes.

Telophase 2 develops the nuclear envelope and separates the nuclei of the daughter cells into 2. Nuclear division id followed by cytokinesis (division of cytoplasm). Telophase 2 result sin 4 haploid daughter cells with one chromatid from each chromosome.

Answer:

Explanation:

    A bay horse is a black-based animal with the agouti gene, which is the modifier that limits the horse’s black color to its points (legs, mane, tail, eartips). The black-based horse can be either homozygous for the extension allele (two copies black – EE) or heterozygous (one copy black, one copy red – Ee). Because black is dominant, an Ee horse will appear black-based.

      A horse can carry the agouti gene whether it is black or red (this is why a black horse bred to a chestnut or sorrel horse may produce a bay). It is impossible to tell phenotypically (from looking at the horse) if it is homozygous or heterozygous.

     This means that when you cross a cremello (a sorrel/chestnut with two copies of the cream gene) on a bay (black with agouti), you can get buckskin, palomino or smoky black, depending on the horses’ exact gene combination.

     references:

Answer:

buckskin(The horse has a tan or gold colored coat with black points (mane, tail, and lower legs))

palomino(gold coat and white mane and tail, the degree of whiteness can vary from bright white to yellow)

smoky black(coat is either black or a few shades lighter than true black)

Explanation:

Answer:

Because it takes some time to adapt to the new level of light in the environment

Explanation:

Our inability to see when moving from a bright place to a dark room is due to the time it takes for our eyes to adjust from cone to rod activity, which is better suited for low-light conditions. This adjustment process leads to a temporary period of impaired vision known as dark adaptation.

We cannot see properly when we come out of a bright room into a dark one because our eyes need time to adjust to the lower levels of light. In a bright environment, our vision is dominated by cone activity, providing us with color vision and sharpness of sight. When we move into a darker environment, our eyes gradually switch to relying more on rod activity.

Rods are more sensitive to light but provide no color information and are more effective in low light. The transition from a well-lit area where cones are active, into a dark area where rods become more active, takes time, causing a temporary inability to see in the dark. This also explains why animals like owls and bats can see in what appears to be pitch darkness to us; their eyes are either more sensitive to light or adapted to different wavelengths, allowing them to see with less light than humans require.

Ultimately, what is experienced as 'darkness' is a limitation within our own visual system rather than a complete absence of light. With time, our eyes adapt, and we begin to see better in the dark theater or room, though it may never appear as bright to us as the outside because our perception of brightness is not directly proportional to the number of photons received.

What would a graph of oxygen production look like for this forested area?

A line that is increasing

Explanation:

It is an established fact by scientist that availability of trees increases oxygen rate in an environment. From the above question, the increase in number of trees as allotted by increase in years reflect an increase in oxygen available. Trees makes use of carbondioxide exhale by humans while humans make use of oxygen exhale by trees.  

Answer:

Molecular clock can be described as a technique which scientists use for determining when two life forms might have diverged based on the mutation rate which occurs in biomolecules.

Molecular clocks can be used against infectious diseases because the infection causing agents such as bacteria or viruses contain DNA and RNA. Mutations constantly arise in these infectious agents at the time of their replication. Molecular clocks can help us to sequence different infections and check how similar and different they are to each other. Based on the similarities and differences we can determine the time of the disease and its treatment.

A.  Report her results in a scientific journal - should be the action that the biologist should do next

Explanation:

Once conducting an experiment a biologist or a scientist should record the values, observations and inferences correctly because science requires construction of all data, facts, values, explanations, observations, and predictions that are observed and evidenced.

Research findings are published in a scientific journal because the research findings are stored, saved and can easily be referred for future reference.

This will be evaluated by other academicians and scientists and can be compared with past results to value the achievements made by the current researcher.  This will also give way for future prospects in the research.

This will add academic credibility to both the biologist and her institute. When presented in a literature form, this can be accessed by scientists, academicians, peers and others to refer and cite valuable information in their research.  

Others can use the findings to help with advancements of the research in the same topic. It gives an immense feeling for the biologist or any researcher to see his/her work being published on a recognized journal and will encourage to work more.

Answer:

A scientific inquiry can be described as the different ways in which scientists tend to study about the phenomenons occurring in the natural world.

To make advances in scientific inquiries, scientists have to come forward with better technologies than the past to get a better understanding of the events occurring in the natural world.

For example, the telescope was the technology designed by Galileo in 1609 for astronomical observations. The reflecting telescope was designed by Newton in 1668 which was far better than Galileo's telescope and could make better observations.

The development of reflecting telescopes, initially driven by the need for more accurate astronomical observations, showcases how scientific inquiry spurs technological advances.

Answer: c) Cat

Explanation:

A heterotroph is an organism which depends on plants or other animals for food because it cannot manufacture its own food. All animals are heterotrophs while green plants are autotrophs because they can manufacture their own food using chlorophyll in a process known as photosynthesis. Heterotrophs feed on complex organic food materials.

Answer:

Answer: there must be genetic variation in the population

Explanation:

A PEX

For natural selection to happen, the system must not be in Hardy-Weinberg equilibrium. This means that there must be variation in the population, and that the frequency of alleles in the population must be changing over time.

Additionally, the variation in the population must be heritable, meaning that it can be passed on to offspring. This allows certain traits to be passed on more frequently than others, leading to changes in the population over time.

Competition for resources is actually an important driver of natural selection, as it leads to differential survival and reproduction based on traits that are advantageous in obtaining resources.

The population size and carrying capacity may also play a role in natural selection, but they are not essential requirements for it to occur.

All organisms having the same alleles is not possible in a natural population due to mutations, genetic drift, and gene flow, and it would actually limit the potential for natural selection to occur.

Answer:

The rock pocket mice rely on their fur color for camouflage. So, on the tan sand more light colored mice will survive because they blend in and on the dark lava rock more dark colored mice will survive and the allele for dark fur will be passed on to their offspring

Owing to the definition of fitness as being an organism's ability to survive in an environment, the fact that the color of pocket mouse aligns or blends with the color of their niche protects them from predation.

Therefore, pocket mouse select their living area based on their color in other to conceal their presence and keep them safe, hence, increasing their fitness level.

Answer:

The correct option is A) a new combination of inherited traits that can appear in the offspring

Explanation:

Meiosis can be described as a type of cell division which occurs in the sex cells only. This kind of division causes the chromosome number to be reduced to half of that of the parent cell. This happens so that the chromosome number can be maintained in a fertilized zygote.

The phenomenon shown in the picture is of crossing over. Crossing over is the process by which homologous chromosomes exchange DNA segments so that genetic variation can occur among the parents and offspring.

Baby penguins are left to fend for themselves from the time they hatch, so they quickly become self-sufficient.

D.

The success of a species depends on the number of offspring that survive long enough to reproduce.

Answer:

D

Explanation:

I got this exact same question on Study Island.

"The success of a species depends on the number of offspring that survive long enough to reproduce, not just the number of offspring produced at a time or even in a lifetime. A penguin who has only one young can devote a lot of time, attention, and care to it, greatly increasing its chances of surviving long enough for it, too, to reproduce. An octopus, on the other hand, usually dies shortly after reproducing. A young octopus has no parent to protect or teach it, so the vast majority of octopi do not survive long enough to reproduce." -Study Island
