A dispersion pattern that indicates that resources are abundant, evenly distributed with little interaction within individuals is:_______.

Answers

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.

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).

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]​

Answers

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.

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.​

Answers

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.

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.

Answers

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.

The statement that best describes a difference between the nitrogen and carbon cycles is the nitrogen cycle requires a process called nitrogen fixation that is carried out by certain bacteria.

What are the main differences between the nitrogen and carbon cycles?

The main difference between nitrogen cycle and carbon cycle is that nitrogen cycle describes the conversion of nitrogen into multiple chemical forms and its movement between the different ecosystems. Whereas the carbon cycle describes the movement of carbon and its multiple chemical forms between the atmosphere, lithosphere and hydrosphere.

Microbes are involved in the nitrogen cycle process. Both plants and animals participate in the carbon cycle.
