What is an example of physiological adaptation?
(Give me a thanks and I will make you brainiest)
Answers
Answer:
An example of physiological adaptation is the development of a thicker fur coat in animals living in colder climates. This adaptation helps to insulate the animal and keep its body temperature regulated. Other examples of physiological adaptation include the ability of some animals to hibernate in winter, changes in the shape of feet and claws to allow better climbing, and changes in the shape of beaks to allow better feeding in different environments.

Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:
Evidence:
Reasoning:
Answers
Answer:
The earth would eventually become become a brown and grey wasteland and the blue sky and rainbows and things like that will be rare rain would be highly acidic
Evidence: There are less people which means less cars will be driven less oil will be used etc. also fossil fuels are non renewable resource which means fossil fuels will be harder to find overall diving up prices of gas,heating,etc which might make Deter people from using fossil fuels and switching to something cheaper. At this point to people will dislike fossil fuels more then now.
Reasoning: I think people won’t like fossil fuels for 2 good reasons. First the driven up price. Second there will be noticeable effects from fossil fuels it 2050. It can make crops harder to grow which could lead to famine and a Recession because driven up food prices and it will hurt the economy. Towns will slowly flood. Arctic species will die so on. So a poor family’s that can’t afford food won’t spend more money on something that overall hurts them. They will despise people who use fossil fuels and it will become socially wrong. Civilization at that time might also be working on them self. Population decreased a major amount. Something bad happened. And if what ever caused the decline in population was caused by humans which there’s no way to tell, they might try to improve human habits try not to begin wars, work on helping each other, and most importantly don’t harm there plant.

Answers
Answer:
Explanation:
It helps to maintain homeostasis through the release or conservation of warmth. Blood vessels expand and contract when they react to outside organisms, such as bacteria, and to internal hormone and chemical changes. These actions move blood and heat closer to or farther from the skin surface, where heat is lost.

Explain why a lack of gravity might cause muscles to weaken
Answers
Answer:
Lack of gravity causes you to use less work to move your muscles.
Explanation:
If on Earth your arm weighs 3 pounds, the muscle will only have to move 3 pounds of force. For example, if you were to go on the moon, your arm would have the same mass but there would be less gravity pulling it dow. So now your muscles only need to pull 1 pound. Over extended periods, you would be working less, thus not using your muscles to fullest potential and in result you would get weaker.

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.

Early succession plant has a characteristic of producing a lot of seeds, smaller size and short lived. Therefore, the correct statements are option A, option C and option D.
What are early succession plants?Early succession plants are plants that quickly adapts in areas that have been recently cleared and have harsh environments. These plants can easily grow in areas having low soil fertility, lack of water and high exposure to sunlight.
These plants produce a lot of seeds, are smaller in size, and short lived. High reproductive capacity, fast growth, tolerance to harsh conditions, short life cycles are other characteristics of an early succession plant.
Weeds like dandelions, annual rye grass and shrubs like fireweed are some of the examples of early succession plants. These plants have also the ability to fix nitrogen in the soil to improve the soil quality for plant growth. However, their seeds do not germinate best in shade.
Therefore, early succession plants produce lot of seeds, smaller in size and short lived.

What type of response occurs when you watch someone eating a lemon and your face puckers?
external response
sour response
internal response
lemon response
Answers
Answer:
The type of response that occurs when you watch someone eating a lemon and your face puckers is an external response. An external response is a physical reaction that is visible to others and occurs in response to a stimulus, in this case, the sight of someone eating a lemon. It is also sometimes called a behavioral response.
An internal response, on the other hand, is a response that occurs inside the body and is not visible to others. For example, when you eat a lemon, you may experience an internal response such as an increased production of saliva in your mouth or a sour taste in your mouth.
A sour response is a type of internal response that refers specifically to the taste of something that is sour, such as a lemon.
A lemon response is not a commonly used term in psychology or physiology. It could refer to any type of response that is related to lemons, such as the external response of puckering your face or the internal response of experiencing a sour taste.

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.

Explanation:
Bacteria breaking down nitrogen compounds releases free nitrogen.Explanation:The nitrogen cycle is a process in which nitrogen is recycled through different components of the environment. Bacteria play an important role in this cycle by breaking down nitrogen compounds found in plants, animals, and soil. When bacteria break down these compounds, they release free nitrogen into the environment. This free nitrogen can then be used by other organisms like plants to create proteins and other essential molecules.

A pedigree chart is used to _______.

Answers
A pedigree chart is used to track inherited traits through generations.
A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.
Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
