why does deforestation lead to increased carbon dioxide in the air​

why does deforestation lead to increased carbon dioxide in the air

Answers

Answer:

Because trees create oxygen, and when we inhale and exhale we are turning that oxygen into carbon dioxide and with less tree's we're creating more carbon dioxide then the trees and since trees breath carbon dioxide without them it has nowhere to go

Answer: Deforestation leads to carbon dioxide in the air because trees put oxygen into the air and take carbon dioxide out of the air. If we cut down trees, there will be more carbon dioxide.

Komodo dragons (a lizard species) and red-tailed boas (a snake species) are both reptiles. They share a common ancestor population that lived about 250 million years ago, but they have been separated in different environments, with different food sources, for millions of years. Komodo dragons and red-tailed boas have some shared structures. They also have some differences in their structures.



1.Why do Komodo dragons and red-tailed boas have some shared structures and some different structures?

Komodo dragons (a lizard species) and red-tailed boas (a snake species) are both reptiles. They share
Komodo dragons (a lizard species) and red-tailed boas (a snake species) are both reptiles. They share

Answers

They have similar characteristics and structures because they are both reptiles and came from a common ancestor. That meant that, going back in time, both of these creatures were once one common, ancestral animal. Once the animals were put into different environments, they changed and evolved overtime in order to adapt to the challenges in the habitat specific to them. But, because they come from a common ancestor, they started from the same ‘base’, and will still share similarities today.

Komodo dragons and red-tailed boas have some shared structures because they both evolved from a common ancestor population that lived about 250 million years ago.

What is the difference has come over the time in these species?

Over time, as these two species separated into different environments with different food sources, they underwent separate evolutionary trajectories that led to differences in their structures. However, many of the underlying genetic and developmental mechanisms that produced their ancestral structures are still present in both species.

For example, both Komodo dragons and red-tailed boas have scales, which are a common feature of reptiles. Scales serve to protect the skin from abrasion and injury, as well as to reduce water loss. They also both have a vertebral column, which provides support for the body and protects the spinal cord.

At the same time, Komodo dragons and red-tailed boas have differences in their structures because they evolved in different environments and have different feeding strategies. Komodo dragons are large, carnivorous lizards that use their sharp teeth and powerful jaws to hunt and kill prey, while red-tailed boas are constrictor snakes that use their muscular bodies to suffocate and swallow their prey whole.

As a result, the structures of their jaws, teeth, and digestive systems are adapted to their respective diets and hunting strategies, and differ in significant ways.

Overall, the shared and different structures between Komodo dragons and red-tailed boas reflect both their common evolutionary heritage and their divergent evolutionary trajectories.

Do you think that a plant-based or a meat-based diet is more nutritious, or are they both equally nutritious? Why does a plant-based diet require fewer resources to produce? Do you think people should eat less meat? Why or why not?

( Please give me a good detailed answer on this everybody, please!! )

Answers

A plant based diet has a much higher nutritional value. A plant based diet requires less resources because plants grow naturally and anyone can grow vegetables. On the opposing side, not everyone can simply buy an animal to produce meat. For the greater health of all people, it is very important that people eat less meat in the daily lives. Red meat can provide many health complications and consequences. For example, it is proven that red meat such as steak can give you cancer. Don’t get me wrong, meats offer ale nutritional value such as protein, however the risks out number the benefits. Many foods can provide the necessary protein to stay healthy without providing health risks. In the end, meat in moderation is alright, but you should highly consider replacing meats with other sources of protein.

Have a lovely day! Merry Christmas!
I think that a meat based diet is more nutritious since it has the proper "actual" proteins and you can have a proper balanced diet with all the ingredients including meat and vegetables so you're getting everything.

What is the evolution of hominins?

The evolution of hominins is a known process where by hominins (a group of primates including modern humans and similar evolutionary ancestry) had morphed over time. The changes in shape and structure of the skulls are evident in the fossil record exhibits of the hominin skull over time, indicating a process of evolution.

These changes include a reduction in the size of brow ridge and the jaw, an increased capacity in the cranium, a more prominent nose, and a vertically oriented skull that is equally round. These modifications reflect hominins' alterations to dynamic environments, nutrition, and social constructs as they evolved over time.

Why is it that a leaf cannot be directly tested for starch by adding iodine?

Answers

Iodine is a starch test that is used to detect the presence of starch in a substance. However, when iodine is added to a leaf, it reacts with other substances in the leaf, such as chlorophyll, and not with the starch. Chlorophyll is a pigment present in leaves that gives them their green color, and it can interfere with the iodine test and make it difficult to determine if starch is present in the leaf. To test for starch in a leaf, it is necessary to first remove the chlorophyll by boiling the leaf in water or by using a solvent such as ethanol. After the chlorophyll is removed, the iodine test can be performed on the remaining material to detect the presence of starch.

Why are coconut trees found in coastal areas?

Answers

The warm, humid climate near the ocean is ideal for coconuts, which require constant moisture. Coastal locations also provide easy access to water, whether from rainfall or seawater absorption through the roots, to keep the coconut palms hydrated. Sandy soil, abundant at the coast, allows the coconuts' extensive root systems to spread and helps retain moisture.



In addition, coconut palms are well-adapted to withstand salty winds and wind-borne salt spray from the ocean, bending but not breaking in strong storms. Their flexible trunks and fan-like leaves help them cope with windy conditions.


Coconuts near coastal areas provide ecological benefits as well. Their root systems stabilize beach soil and reduce coastal erosion. Coconut palms offer shelter and food for coastal wildlife like birds and crustaceans.



In summary, the combination of warm, moist air; access to water; suitable soil; and ability to endure coastal weather make seaside locations a coconut palm paradise where these trees can thrive.


__________________________________________________________

Coconut trees are found in coastal areas because they thrive in tropical climates with high humidity and abundant rainfall.
