Explanation:
If we do end up colonizing Mars, Earth could slowly get better as time goes on, but when we do colonize Mars, wont we just do the same thing we did to Earth?
Answer:
Yes it could be, here are the pros.. Colonizing Mars is one of the most promising backup plans for humanity . Mars is relatively close to our Earth . Colonizing Mars may become possible in just a few decades . Many celebrities support those plans . Many scientists advocate for this kind of backup plan . Extraction of additional natural resources . May help with the search for other life forms . We could learn as global human species . Humanity needs challenges to progress . Knowledge is power . May help to mitigate the overpopulation problem on Earth . Colonizing Mars is an image project . Future generations would be able to adapt quite quickly on Mars . May be a good long-term investment for institutional investors
But there are also some cons.. Colonizing Mars is extremely expensive . It takes a while to travel to Mars ; Lack of water may become a serious problem . Plenty of insecurity involved in this plan . Completely different living conditions . Humans need protective equipment before going outside . It’s freezing cold on Mars . Some people have to make the beginning . May not be justifiable from an ethical standpoint . Colonizing Mars may conflict with religion . Money can be better used to solve our problems on planet Earth . Some scientists believe that efficient live on Mars will not be possible . Quality of life on Mars would be much lower . Rather insecure food supply . Radiation may become a problem . Still unclear if living on Mars is sustainable . We would alter the balance in our universe . Colonizing Mars can be dangerous . Space exploration implies significant pollution . Other life forms may not be welcoming towards us humans . Short-term costs vs. long-term gains
In conclusion, no it would not be a good idea.

A dispersion pattern that indicates that resources are abundant, evenly distributed with little interaction within individuals is:_______.
Answer:
Uniform dispersion pattern.
Explanation:
Uniform dispersion pattern is a type of dispersion pattern in which resources are present in abundant quantity as well as evenly distributed with little interaction within individuals. Due to abundant quantity of resources , the population of organisms increases that leads to more population of individuals in the ecosystem. Due to abundant amount of resources, there is less competition as well as interaction between individuals that are present at that time.

Where is the diaphragm located in relation to the lungs?
a) inferior
b) medial
c) superior
{ Relating to a crash course video called: Respiratory System Crash Course}
[any information would be very much appreciated! thank you :D]
Answer:
A. Inferior
Explanation:
If you're not familiar with anatomical terms, a quick summarization would be:
-Inferior: below
-Superior: above
-Medial: towards the midline of the body
Upon googling a picture for the diaphragm and lungs, you will see that the diaphragm is a muscle situated directly below the lungs. The phrase "located in relation to" is asking you specifically "when compared to". Therefore, since the diaphragm is located below the lungs, the answer would be inferior.
I hope this answer and explanation helped you understand this topic a little bit more!
The diaphragm is located in inferior to lungs.
What is diaphragm ?
In mammals, the diaphragm is a dome-shaped, muscular and membrane tissue that divides the thoracic and abdominal compartments.
It is the primary respiratory muscle.
The diaphragm gets contract and flatten up during we inhale, while the chest cavity expands.
Vacuum is created due to contraction, which pulls air into the lungs.
Exhalation relaxes the diaphragm and causes it to return to its domelike shape, pushing air out of the lungs.
So we can conclude that the diaphragm is the muscle that connects the chest cavity to the abdomen and it is the primary respiratory muscle, when one breathes in, the diaphragm muscle contracts, causing the lungs to expand and vice versa, and most importantly it located inferior to lungs.

High Altitude Living Quick Check
Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.
What do you mean by Adaptations?
Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.
Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.
Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

Nonvascular plants have never evolved to the size of vascular plants, most likely because they lack Select one: a. a photosynthetic mechanism. b. an efficient mode of respiration. c. an efficient system for conducting water and minerals. d. nutrient and water absorption mechanisms. e. They lack all of these choices.
Answer:
The correct answer is c. an efficient system for conducting water and minerals.
Explanation:
Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.

25. A cell has 20 amino acids. How many molecules of tRNA are in the cell?
1. Four
2. Three
3. More than 20
4. At least twenty
5. Fifteen
6. I do not know.
Answer:
I think no 3 will be the answer.
In cell one amino acid can bind with two or three different tRNA during protein synthesis in the translation process, hence 3 option is correct more than 20 molecules are found.
What is tRNA?Because they can read nucleic acid words (like mRNA codons) and transmit the relevant messages, tRNA molecules serve as translators of amino acids. for each of the 20 amino acids.
There is a tRNA some amino acids bind to 2 or 3 different tRNAs, so cells may contain as many as 32 different tRNAs. Possibility of more than one tRNA and more than one anticodon for an amino acid, there is often only one aminoacyl tRNA synthetase for each amino acid.
Enzymes known as transfer RNA (tRNA) synthetases are responsible for joining a particular amino acid to its associated tRNA in order to produce proteins at the ribosome.
Therefore one amino acid can bind with two different tRNA in a cell during translation, hence option 3 is correct.
