Answer:
Keratin
Explanation:
The epidermis cells are constantly undergoing mitosis so that the outer dead cells containing keratin are rapidly replaced as they fall off, which occurs after so many days.
Plants can usually be found on the beach near the sand. Predict the outcome if these plants were killed.
The outcomes if the plants were killed:
When a plant dies, that nutrition is locked up within the plant's cells. As the detritivores digest the dead plant and poop out what they can't use, that waste (called grass) becomes prime food for aerobic bacteria to work its magic and release even more nutrients.Plants produce oxygen, clean and retain water, and plants form the basis of our entire food chain.Without trees, formerly forested areas would become drier and more prone to extreme droughts.Find more information about "Plants" here:

Killing beach plants can lead to increased erosion, loss of biodiversity, and damage to coastal ecosystems. These plants are essential for stabilizing sand, forming dunes that protect inland areas, and supporting various forms of wildlife.
If beach plants were killed, there would be several ecological consequences. Plants on a beach, especially those in dune ecosystems, play a critical role in sand stabilization. They have adapted to thrive in the harsh, dry conditions of the beach and are drought-resistant. Their roots bind the sand together, preventing it from being easily eroded by wind and water. Without these plants, beaches would be much more vulnerable to erosion.
Additionally, these plants also support a variety of wildlife; they provide habitat and food sources for insects, birds, and other animals. Without vegetation, the beach ecosystem would lose biodiversity. Furthermore, the destruction of plant life could lead to a lack of sand dune formation which is essential for providing a barrier against storms and high waves, protecting inland areas from saltwater intrusion and flooding.
Finally, should the situation escalate, it might lead to long-term ecological damage, altering the coastal landscape dramatically and possibly affecting human communities that rely on the beach for protection and recreation.

if an earthworm eats enough matter that it consumes 100 grams of nitrogen in its lifespan, how much nitrogen did it release into the soil
Answer:
Option C
Explanation:
If an earthworm eats enough matter that it consumes 100 grams of nitrogen in its lifespan, how much nitrogen did it release into
the soil?
(A) 10 grams
(B) 27 grams
(C) 73 grams
(D) 100 grams
Solution -
Worms are considered as eating machines which take in organic matter and break it down into smaller pieces such as nutrients. These nutrients are then taken up by plants.
As per an estimate, an earthworm absorbs nearly 27% of the available nitrogen in their food.
The remaining available 73 percent of nitrogen is broken down and available as nutrients in the soil.
Therefore, out of 100 grams nearly 73 grams of nitrogen is released into
the soil

The way that rainforests and coral reefs are different from ecosystems with few species is that they contain large amounts of life forms, and they provide shelter and protection for the life forms that inhabit them. To know more......
Coral reefsCoral reefs are important ecosystems that are home to many marine lives, providing them with shelter and protection. It is estimated that approximately 65% of marine fish live in this important habitat, therefore, its preservation is essential.
RainforestsTropical forests are those located within the equatorial zone, between the Tropics of Cancer and Capricorn, approximately 28° south and north of the equator. This location provides the incidence of high temperatures and also a significant amount of rainfall. The characteristic of tropical forests is the presence of tall trees very close to each other, forming large regions of ground covered by shade. This soil, in turn, is quite rich and has a layer of fallen leaves from trees, in addition to dead animals. If we take into account the immense diversity of plant and animal species in tropical forests, it is not difficult to imagine how rich this soil is in nutrients and, therefore, conducive to the proliferation of life.
With this information, we can conclude that the big difference will be the amount of life forms in these places.

What happens in hibernation?During hibernation, the animal's body remains inactive, its temperature drops considerably, and blood flow and heartbeat are reduced. The reduction in metabolism causes energy expenditure to be reduced and, consequently, these beings save nutrients.
In winter, food is very rare and the water in some rivers freezes. With no water and no food, the solution is to hibernate in a sheltered place until spring. When sleeping, bears use less energy. And they get the little energy and water they need from their own fat when they hibernate.

Predict using your knowledge of mitosis checkpoints what would most likely happen if the checkpoint proteins during interphase malfunctioned at every check and the cell is permitted to progress to mitosis?
A. The cell would have the organelles it needed for each new daughter cell.
B. The cell would be able to make more of itself at a faster rate.
C. The cell would not be able to continue dividing and would be destroyed.
D. The cell would have issues with chromosome number or size of the cell
If checkpoint proteins during interphase malfunctioned and the cell entered mitosis prematurely, it would likely lead to issues with chromosome number or size of the cell, potentially causing mutations or cell death. The Correct Answer is Option.D.
Explanation:The question at hand involves predicting the consequences if checkpoint proteins during interphase malfunctioned at every stage, allowing the cell to prematurely enter mitosis.
It is crucial to understand that the cell cycle checkpoints, including those in interphase (G1, S, and G2 phases), are fundamental to ensuring cells divide correctly, with undamaged DNA and adequate size. If these checkpoints malfunction, the cell would bypass critical assessments for DNA damage, replication completeness, and cellular size, potentially leading to severe consequences such as chromosomal aberrations and inappropriate cell size.
Therefore, the most likely outcome of such malfunction would be D. The cell would have issues with chromosome number or size of the cell. This scenario could lead to mutations, cancer development, or cell death, emphasizing the importance of the stringent regulation of the cell cycle.

What factor limits the number of eclipses per year?
Answer:
The tilt of the moon's orbit around the earth
Explanation:
On average of twice a year, throughout it's orbit, the moon will create a 180° angle with the Earth making the Earth's shadow visible on the surface of the moon causing a solar eclipse.
The factor limits the number of eclipses per year is the inclination of the moon's orbit around the earth.
Eclipses are part of the phenomena known as syzygy, which occur when a planet or the Moon is in line with the Earth and the Sun.
For an eclipse to occur, the Moon must be in the same plane as the Earth and the Sun, a plane that, precisely to facilitate eclipses, is called the 'Plane of the Ecliptic'.
The plane of the Moon's orbit is inclined with respect to the ecliptic, approximately 5.1º.
This causes that during the movement of the Moon around the Earth, the Moon only touches the plane of the ecliptic at two points.
Due to this inclination between the orbits, and as eclipses require the almost perfect alignment of the three stars (Sun, Earth and Moon), eclipses occur very few times throughout the year.
Therefore, we can conclude that the factor limits the number of eclipses per year is the inclination of the moon's orbit around the earth.

Blood
Circulatory
Oxygen
Vessels
Please help Thanks
Answer:
blood; vessels; oxygen; circulatory
Explanation:
The first blank comes after the phrase "This organ is your heart, which pumps your ________ ". Our heart is the organ that works hard to pump oxygenated blood throughout our bodies so that we can live. So, that first blank should be "blood".
The second blank comes right after the first: "...your blood through blood ________ to all parts of your body". Blood travels through vessels; there are two kinds: arteries and veins. Here, the second blank should be "vessels".
The third blank is "_______ and food and removes waste". Here, it is talking about how certain beneficial substances are transported through the body and how harmful substances are removed. "Oxygen" should go here because all parts of our bodies need oxygen in order to be able to function properly.
The last blank, by elimination, must then be "circulatory". Putting it in, the sentence will read: "...your lungs bring in the oxygen that your circulatory system...". This makes sense because the circulatory system helps to transport oxygen through blood all over the body.

Which prediction is true based on this population pyramid?
The population is growing slowly.
The population is growing rapidly.
The population is declining.
The population is not growing.
Based on the wide base of Angola's population pyramid, the population is growing rapidly. The demographic transition model supports this, as Angola is in Stage 2 with high birth rates and dropping death rates. In contrast, Italy's narrower base indicates a declining population in Stage 5.
Explanation:The prediction of population growth can be determined by examining the population pyramid. When a country like Angola exhibits a wide base in its population pyramid, it is indicative of a high birth rate, suggesting that the population is growing rapidly. Meanwhile, countries like Italy display a top-heavy pyramid with a narrow base, which signifies an aging population and potentially a declining population size. The demographic transition model further explains that in Stage 2, where the death rate has fallen but the birth rate remains high, populations experience rapid growth. On the other hand, Stage 5 indicates a population with birth rates lower than death rates, leading to population decline.
The population pyramids reflect the historical demographic changes due to births, deaths, and migrations and can also hint at socio-economic changes. In addition, population growth rates are subject to change based on factors such as national wealth and societal values influencing birth and death rates.
