According to the video, fossils provide each of the following except: a. Examples of transitional species b. A complete record of past life on Earth c. Physical proof of extinction and speciation d. Evidence that evolutionary change tends to be gradual
Answer:
According to the video, fossils provide each of the following except:
b. A complete record of past life on Earth
Explanation:
The reasons behind this answer are that one single fossil can include the whole record of life forms on earth's history. It might only contain a fraction of a form of life because the majority of fossils don't include more than woven bone. Therefore, it is only a fraction of the living being. also, it doesn't contain a record of its evolutionary chain or that the species of the fossil became extinct. We could find a crocodile fossil and they are still alive in modernity.

What happens a few days after fertilization ? A. The baby can be felt moving . B. Cells have started differentiating . C. The zygote completes its first division D.The eyes develop .
Answer:
B
Explanation:
During the third week after fertilization, the embryo begins to differentiate cellularly. Differentiation is the process through which unspecialized cells become specialized. Differentiation happens when certain genes are activated while others are silenced.
A few days after fertilization, cells have started differentiating, which is in Option B, as here, after the zygote formation, there is the formation of the morula, blastula, and gastrula, and then finally the baby is produced.
What is the significance of the cell division after zygote formation?In the cleavage process, the single-cell zygote rapidly divides into multiple cells and then continues to divide and differentiate into different types of cells that will eventually form all of the different tissues and organs of the developing embryo, including cells such as those of the nervous system, the heart, the muscle, the skin, and so on.
Hence, a few days after fertilization, cells have started differentiating, which is in Option B, as here, after the zygote formation, there is the formation of the morula, blastula, and gastrula, and then finally the baby is produced.

This is the jaw of the ancient saber-toothed cat, an ancestor of the modern tiger. You can see that the teeth of the saber tooth were nearly twice as large as the teeth of today's tigers. These teeth were so large that they stuck out the the saber-tooth's mouth when it was closed. Their food included large mammals such as elephants, rhinos, and other huge herbivores. Predict a change in the environment could have led to the gradual development of the smaller front teeth we see in the modern-day tiger. A) There was a change from tropical forests to grasslands. B) Competition from other big cats such as lions, cheetahs, and leopards. C) The disappearance of the huge herbivores that saber toothed tigers hunted. D) The large teeth were no longer an advantage for catching prey and survival.
Answer:
C
Explanation:
The most plausible environmental change leading to smaller front teeth in modern tigers compared to saber-toothed cats is the disappearance of large herbivores which initially required saber-tooths to have massive teeth for hunting.
Explanation:The question asks to predict a change in the environment that could have led to the development of smaller front teeth in the modern-day tiger, compared to their ancestor, the saber-toothed cat. Analyzing the given options, the most plausible change is C) The disappearance of the huge herbivores that saber-toothed tigers hunted. These large prey required the saber-tooths to have massive teeth for capturing and defeating them. When these herbivores declined, the selective pressure for such large teeth would have diminished, leading to the smaller, more versatile teeth seen in today's tigers that are adapted to hunt a more varied and less robust prey base.
Explain the amazing cell process
that causes the grow and repair of
body cells, such as skin and nails?
Please help mee....
Answer:
The cell process that causes grow and repair of body cells including skin and nails is called mitosis.
The process of mitosis increases number of cells and enable them grow and also replaces the dead cells or lost cells with new cells for proper functioning of cells. Mitosis is important for the replacement of cells which constantly lost and grow.
In the mitosis process, parent cell split into twin daughter cell and carry identical DNA which helps in replacement of lost cells and growth of cell as in skin and nails.
Hence, mitosis helps in the renewal and growth of skin cells and nails.

Will apophis hit earth in 2029
Answer:
On April 13, 2029, Apoptosis will pass Earth closer than geosynchronous communication satellites, but will come no closer than 31,200 kilometres (19,400 mi) above Earth's surface.
Explanation:
Final answer:
Apophis is not expected to hit Earth in 2029. Earth-approaching asteroid orbits are unpredictable over very long timescales, but Apophis has been closely monitored and is not considered a threat. The probability of a catastrophic asteroid impact in the near future is very low thanks to ongoing surveillance projects and impact prevention technologies.
Explanation:
The asteroid known as Apophis is projected to make a close approach to Earth in the year 2029, but it is not currently expected to hit our planet. While the orbits of Earth-approaching asteroids can be predicted over short time scales, they are significantly affected over longer periods due to gravitational interactions with the planets. However, dramatic destabilizing events like impacts or gravitational ejections are expected on timescales of about a hundred million years, which is a very short time in comparison to the solar system's age.
It is important to continue monitoring such near-Earth objects (NEOs) for any course changes. Though the chances of a catastrophic impact are slim, our capability to predict and potentially avert disaster improves as we enhance our technology and understanding. Initiatives like the NASA Double Asteroid Redirection Test (DART) mission and the Spaceguard Survey work to identify hazardous asteroids and develop strategies to protect Earth from possible future impacts

Explanation:
.Within the visible spectrum of light, there are many colors: red, orange, yellow, green, blue, indigo, and violet. What characteristic of each of these colors makes this spectrum of light visible to the human eye?
Each color has a different wavelength.
Each color travels through different substances (mediums) .
Each color must travel a different distance to our eyes.
Answer:
Each of these colors make the spectrum of light visible to the human eye because each color has a different wavelength.
Explanation:
The cones of our eyes are a type of photoreceptor. The cone is the cells in the retina that respond to light. Each different cone is senstive to different wavelengths. In order to see different colors, the light reflected off of objects must have a specific wavelength in order to trigger one of the cone receptors.
The characteristic of each of these colors that makes this spectrum of light visible to the human eye is each color has a different wavelength. The correct option is A.
What is a wavelength?The distance between two successive crests or troughs of a wave is defined as its wavelength. It is measured in the wave's direction.
The light color spectrum contains seven pure spectral colors. They are red, orange, yellow, green, blue, indigo, and violet in order of decreasing frequency to increasing frequency.
Because of the inverse relationship, the order is reversed by wavelength. Violet is the color with the highest frequency. Red light, with the longest wavelength, is at one end of the spectrum. The shortest wavelength is blue or violet light.
Each of these colors has a different wavelength, which is what makes this spectrum of light visible to the human eye.
Thus, the correct option is A.

The bald cypress tree produces seeds that are protected within cones. This tree is found in Florida swamps where heavy rains create floods. The floodwaters spread the cones throughout the swamps. What role do the floodwaters play in the life cycle of the bald cypress?
Answer:
seed dispersal
Explanation:
The baldcypress tree is a known tree of southern swamps. the floodwater act as an agent of seed dissemination of the baldcypress seed.
Floodwaters in the Florida swamps serve a vital role in the life cycle of bald cypress trees by spreading their seeds, which are protected within cones, throughout the swamp. This facilitates reproduction and aids in the survival and propagation of the species.
Explanation:The floodwaters play a crucial role in the life cycle of the bald cypress by serving as a dispersion agent for its seeds. Bald cypresses produce seeds inside cones, which get spread throughout the swamps during floods. This is integral to the reproductive process. The seeds have a superior evolutionary advantage as the hardened tissue coat prevents desiccation and allows dormancy until conditions are favorable for growth. Seeds are then scattered in an expanding geographic range, thereby avoiding competition with the parent plant.

Juan is skipping rocks by the lake. As he picks up a pebble, he notices that it is smooth all over. Which of the following hypotheses is the most likely explanation for how the river rock became so smooth?
Answer:
Erosion
Explanation:
The smoothness of the river rock is attributed to prolonged erosion by water and sand, similar to the erosion process that smooths mountain ranges on Earth. The absence of water and ice on the Moon results in its mountains having a naturally smoother appearance.
Explanation:The smooth surface of the river rock that Juan noticed is most likely the result of erosion by water and possibly sand over a long period of time. This natural process occurs as rocks are tumbled and rolled along the riverbed by the flowing water, causing their surfaces to become smoothed as rough and sharp edges are gradually worn away. The consistent action of water and sand, much like sandpaper, erodes the rock's surface, making it smooth.
This explanation is similar to how mountain ranges can become smooth over time. After mountains are formed by the upthrust of the Earth's crust, erosion plays a key role in shaping their appearance. Factors such as water and ice can wear down the sharp peaks and serrated edges of mountains, leading to smoother, rounded forms. On bodies like the Moon, where there is no water or ice, mountains remain with a smoother appearance due to the lack of these erosive processes.

D
Sometimes, species evolve to be more complex.
Answer:
C. Very few species have ever gone extinct.
Explanation:
784 extinctions have been recorded since the year 1500 alone
The false statement is Very few species have ever gone extinct, as scientific evidence suggests up to 99.9% of species that have ever lived are now extinct. Option C is correct.
The false statement among the options provided is Very few species have ever gone extinct. This statement contradicts the widely accepted scientific understanding that up to 99.9% of all species that have ever lived on Earth are now extinct.
There have been five mass extinctions in Earth's history that have caused the disappearance of a large percentage of species, and current rates of extinction are higher than the background extinction rates largely due to human activities. Moreover, the process of speciation continues to create new species, which sometimes evolve to be more complex.
Hence, C. is the correct option.

Final answer:
The incorrect statement in describing the structure of the ear is B) The inner ear consists of the auricle and auditory ossicles. The auricle is part of the outer ear, and the auditory ossicles are in the middle ear, not the inner ear.
Explanation:
If you were explaining the structure of the ear to a friend and considering what components would not be part of such an explanation, let's evaluate the options provided:
A) The middle ear consists of the malleus, incus, and stapes. - This statement is correct. The middle ear does contain the three ossicles: malleus (hammer), incus (anvil), and stapes (stirrup).
B) The inner ear consists of the auricle and auditory ossicles. - This statement is incorrect. The auricle and auditory ossicles are not part of the inner ear; the auricle is part of the outer ear, and the auditory ossicles are part of the middle ear.
C) The outer ear consists of the auricle and the external acoustic meatus. - This is a correct description of the outer ear, which includes the auricle (also known as the pinna) and the external acoustic meatus (ear canal).
D) The inner ear contains canals filled with fluid. - This is accurate. The inner ear contains the cochlea and semi-circular canals, which are indeed filled with fluid.
Therefore, the correct answer is B, as it includes elements that are not part of the inner ear's structure.

Since 2000, melting ice from the continent totaled enough to raise sea levels globally by about four tenths of an inch, according to the report which relied on the work of 90 scientists. With what’s already baked into the atmosphere, faster melting land ice will likely add between 7.5 and 9.8 inches to earlier U.N. estimates by 2100, the report said. And because of its position downstream, in an area of “preferential excitement,” South Florida could experience rise at the high end as water sloshes around the planet, Kirtman said. “Think of it as pushing down the ocean [in Greenland]. The ocean is fluid, so it’s going to respond somewhere else and that somewhere else is down here,” he said. In South Florida, planners already confronting flooding from sea rise have been more aggressive in assessing sea rise.

100 POINTS! CORRECT ANSWER GETS BRAINLIEST! How this somatic cell obtain twice as much chromosomes? Body Cells and Germ Cells Your body cells(somatic) are called diploid cells because they contain two copies of every chromosome. However, the two copies are not exact copies because one is from your mother and one is from your father. Diploid cells can be represented as 2n. In humans, the diploid chromosome number is 46. In addition to body cells, you also have germ cells located in your reproductive organs. Germ cells form gametes, or sex cells. The male sex cells are sperm and the female sex cells are eggs. Unlike body cells, gametes have only one copy of each chromosome. These cells are called haploid and can be represented as n. Human gametes thus contain 23 chromosomes. Only DNA in gametes is passed down to the organism's offspring. The DNA in body cells is not.Sexual reproduction involves the fusion of two gametes of different types, resulting in offspring that are a genetic mixture of both parents. The joining of these two gametes is called fertilization. When fertilization occurs, the nuclei of the egg and sperm fuse to form a single nucleus.
The chromosomes of the somatic cells become only to the egg cell. (Option B).
What happens during fertilization?
During fertilization, the nuclei of both the egg and sperm fuse to form a single nucleus in the zygote.
The zygote then undergoes cell division, and the resulting cells have the diploid chromosome number (2n), representing a combination of genetic material from both the mother and the father.
The chromosomes of the somatic cells do not become only the egg cell or only the sperm; rather, they contribute to the formation of a new diploid organism with a combination of genetic material from both parents.

Explanation:
There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.
Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.
Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.
Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.
