Answer:
C) Cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships.
Explanation:
Cladograms are not necessarily helpful because sometimes organisms with similar characteristics can emerge based on environmental factors and not necessarily from the same ancestors. This is the idea of convergent evolution where two species can have same characteristics but are not related at all and since, cladograms are based on depicting evolutionary relationship based on similar characteristics, it fails to take into account the effects of convergent evolution where same characteristics does not necessarily mean same ancestor.
Cladogram is not an evolutionary tree so it does not show an evolutionary relationship or kinship among ancestors and descendants

Why do your fingers look like prunes after swimming for a long time?
Answers
Answer:
pruney fingers are caused by shrinking blood vessels. When you soak in water, your nervous system sends a message to your blood vessels to shrink. Your body responds by sending blood away from the area, and the loss of blood volume makes your vessels thinner.
Answer:
This is because when you swim in a pool for a while your hand seem to be pruney and it is because when the hand is soaked in water, the nervous system sends a message to the blood vessels in your hand to shrink.

pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.

2. Hanging clothes -
3. Walking -
4. Feeding the stray animals -
5. Using back page of paper -
6. Using fan -
7. Watering the plants -
8. Sweeping -
Answers
1. Using a glass when brushing teeth: By using a glass instead of leaving the tap running while brushing our teeth, we can conserve water. Freshwater is a finite resource, and reducing unnecessary water usage is essential for preserving our water supplies and ensuring their availability for both humans and the natural environment.
2. Hanging clothes: Opting to hang clothes to dry instead of using a dryer not only saves energy but also reduces greenhouse gas emissions. Clothes dryers consume a significant amount of electricity, and by utilizing natural methods like hanging clothes, we can contribute to reducing our energy consumption and lowering our carbon footprint.
3. Walking: Walking instead of using vehicles for short-distance travel offers multiple benefits. Firstly, it helps reduce air pollution by decreasing the emission of harmful gases from vehicles. Secondly, walking promotes personal health and well-being, as it is a form of physical exercise. Lastly, choosing to walk reduces traffic congestion and saves fuel.
4. Feeding stray animals: Feeding stray animals is an act of compassion and kindness. By providing food for stray animals, we help prevent their starvation and promote their overall welfare. It also reduces their need to hunt for food in natural habitats, preserving the delicate balance of local ecosystems.
5. Using the back page of paper: Utilizing both sides of a piece of paper helps reduce paper waste and conserves valuable forest resources. Paper production involves cutting down trees, and by maximizing the use of each sheet, we minimize the number of trees required to produce paper products.
6. Using a fan: Using a fan instead of an air conditioner helps reduce energy consumption and lowers greenhouse gas emissions. Air conditioners consume a significant amount of electricity, and by using fans to circulate air and provide cooling, we can contribute to conserving energy resources and mitigating the impact of climate change.
7. Watering the plants: Watering plants is essential for their growth and well-being. By providing them with adequate water, we support their ability to photosynthesize, produce oxygen, and contribute to a healthy ecosystem. Additionally, practicing responsible watering techniques, such as using watering cans instead of hoses, helps conserve water resources.
8. Sweeping: Sweeping instead of using a leaf blower or a hose to clean outdoor spaces reduces energy and water consumption. Leaf blowers and hoses consume significant amounts of electricity and water, respectively. Sweeping not only saves resources but also minimizes noise pollution and prevents soil erosion caused by high-pressure water flow.
Engaging in these activities of conserving natural resources demonstrates our commitment to environmental stewardship and sustainable living. By making conscious choices in our daily lives, we can contribute to the preservation and protection of the Earth's ecosystems for the benefit of current and future generations.

In which of Earth's spheres does the stratosphere exist?
A hydrosphere
B geosphere
C atmosphere
D biosphere
Answers
The answer is Atmostsphere
The stratosphere exists in the atmosphere as one of Earth's spheres. The stratosphere is an atmospheric layer. The stratosphere exists between the troposphere and the mesosphere.
What are the layers present in the atmosphere?The atmosphere is divided into strata based on temperature. These layers are the troposphere, stratosphere, mesosphere, and thermosphere. The exosphere is a separate zone 500 kilometers above the Earth's surface.The stratosphere lies above the troposphere and beneath the mesosphere. Layer is abbreviated as strat. There are strata in this part of our atmosphere. Because there are no storms or turbulence to mix the air, warm, light air is at the top and cold, heavy air is at the bottom. The troposphere layers, where we live, work in the exact opposite way.If you were to climb a mountain in space, you wouldn't put on your warm clothes as you got closer to the top like we do; instead, you'd have to take them off. You don't have to worry about it because there are no mountains high enough to reach the stratosphere.To learn more about layers of Earth’s atmosphere, refer to:

Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.

What structures (Homologous, Analogous, or Vestigial) would be most helpful in studying the selective pressures in an environment. Explain.
Answers
Answer:
Vestigial structure
Explanation:
Homologous structures are physical structures such as organs or skeletal elements present in numerous species that come from a shared common ancestor. Analogous structures are bodily structures that resemble one another superficially and provide a similar function but have evolved separately and do not come from a shared common ancestor (such as the wings of an insect and bat). One vestigial structure present in humans is the appendix. This organ was once vital in the consumption and digestion of uncooked meat, but no longer serves a function.
In the process of origin of species a lot of species has come from a common ancestor as homologous are the organism who have same structures and origin and same function as well while analogous are those who have same structures but functions are different in that case analogous and homologous are also considered as the organism from common ancestors but organism who have vestigial organs are not consider as the organism came from same ansector

Answers
Answer:
Another Brainly Answer
Explanation:
The Amphibian life cycle isn't as simple as it seems. The main Amphibian that has a longer process are called Frogs. Everyone knows frogs, but they are different from most animals such as turtles. The first stage of frogs are when their in eggs of course. These eggs are called "Tadpoles" and look different than most eggs. These eggs are kept in water until they grow. Which brings me to the next stage. When the tadpoles hatch you would start to see something like a baby fish swimming around. That's still the same tadpoles you saw before just hatched. When it comes to this topic most are confused because frogs don't have tails. Well during these stages a tail is used to help them survive in the water and move around. The third stage of these interesting creatures are when they grow legs. That's when they are able to walk on land. They still have their tail of course. It still helps them swim in water. I don't understand much about why they still have a tail if they've grown legs, but that's for me to find out soon. Eventually they grow more and more and get better with their legs and lose the tail. Well the tail doesn't just magically disappear. It's actually absorbed by using something called apoptosis. Then it's pretty much and adult frog.

A geyser shoots water and steam out of the ground. The hottest geysers heat steam to temperatures of 200°C or higher.
Volcanoes, geysers, and hot springs all provide clues about Earth's interior. They also show one of the ways that Earth's layers interact with each other.
1. What do you predict Earth's interior is like? How do its rocks compare to rocks on the surface? Cite evidence that supports your prediction.
Answers
The rocks are comparable to the surface because they are almost certainly metamorphic rock, which is supported by the fact that magma will melt and combine various types of rocks.
What geysers, hot springs, provide clues to Earth's interior?Hot springs and geysers are likewise created by heated underground water; hot springs are more frequent than fumaroles, while geysers are less frequent.
Geysers are created by a surface hole in the Earth's crust that stretches far below the surface. Water is put within the tube. Magma, which is molten rock towards the tube's bottom, heats the water there. Water in the lower portion of the tube near the magma gets extremely hot.
Therefore, Due to their sophisticated plumbing systems, geysers can be recognized from both hot springs and fumaroles, whereas a hot spring and a fumarole differ only in their level of warmth.
