1 How was the Flowing Water Model similar to
flowing water on Earth?
2. How was the Flowing Water Model different than
flowing water on Earth?
3. How I would change the Flowing Water Model to make it more like the actual geologic process on Earth?
Answers
Answer:
Flowing water model is a computer program not the real earth ecosystem.
Explanation:
The flowing water model is a simulated computer program that integrates the land, aster, and groundwater-surface systems and can calculate the demand for each land-use type. Such as agriculture, urban, native, and natural vegetation. It's similar to that of earth's flowing water as it based on the simar feature of the water system as of earth. Due to its just a simulation or model its cannot predict the varieties of the monsoon and ned's a single one-dimensional flow through a network that is set to incorporate time. But the earth is an unpredictable and dynamic system.1. The Flowing Water Model was similar to flowing water on Earth in that it involved the movement of water and sediment, simulating erosion and deposition processes.
It aimed to show how flowing water shapes landforms, like river valleys, canyons, and deltas, similar to natural water systems on Earth.
2. The Flowing Water Model was different from flowing water on Earth because it lacked the complexity and scale of real-world geologic processes.
It likely used simplified materials and conditions, unable to replicate the intricate interactions between water, sediments, and geological structures found in natural environments.
3. To make the Flowing Water Model more like the actual geologic process on Earth, it could be enhanced by incorporating more realistic materials, gradients, and variable flow rates.
Additionally, introducing obstacles and geological formations would mimic the natural complexity of river systems, allowing for a more accurate representation of the Earth's dynamic geological processes.

Justify your choice by writing a hypothesis to explain how it has stopped Claire from breaking down her food. The hypothesis is your first explanation. You will be able to revise it as you do more experiments.
Answers
The complete question is attached to the answer.
Answer:
The correct hypothesis would be - the food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire.
Explanation:
According to the image, we can find that the normal intestine fluid has the same pH as the pH of claire's Intestine fluid which is suitable for the breaking down of the food or protein in particular. It is also found that there is some amount of protein digested which suggests that there is no mutation in the active site.
According to the graph, claire is able to break down or digest the food completely if 1mg proteases enzyme is used so it proves the enzyme is produced less than normal. On the basis of this information, the correct hypothesis would be -
"The food (proteins) are not completely broken down in the intestine due to intestinal Protease production is lower than normal in Claire."

Identify which sentence represents a substitution, which represents a deletion, and which represents an insertion.

Answer:
This question is incomplete as the sentences depicting mutated sequences are not included. The complete part is:
1) The cat was red 2) The fat aca tsa t 3) SHE Has The DG
The answers are:
1. The cat was red - Substitution
2. The fat aca tsa t - Insertion
3. SHE Has The DG - deletion
Explanation:
A mutation, as stated in this question, is an alteration in the nucleotide sequence of a gene, which can alter the gene product. In this question, each sentence is made up of three‑letter words, representing mRNA codons. The sentences are:
THE FAT CAT SAT
THE CAR WAS RED
SHE HAS THE DOG
1. A substitution mutation is that mutation involving the replacement of a nucleotide by another in a sequence. In the sentence; THE CAR WAS RED, R letter was replaced by letter T, hence, the sequence/sentence changed to THE CAT WAS RED.
2. An insertion mutation involves the addition of a nucleotide into the original sequence. In the sentence/sequence; THE FAT CAT SAT, letter A was added in between "fat" and "cat" to change the sentence to THE FAT ACA TSA T.
3. Deletion mutation involves the removal of a nucleotide from an original sequence. In the sentence/sequence; SHE HAS THE DOG, letter O was removed from the sentence to change it to SHE HAS THE DG.

Explanation:
Without the skeletal system, the body could not carry oxygen in the blood. The given statement is true.
What is skeletal system?
The skeletal system in the body is composed of muscle tissue, ligaments, and bone. It is in the bone marrow that hematopoiesis (development of blood cells) occurs. These hematopoietic stem cells (HSCs) from red bone marrow differentiate into erythrocytes, platelets, and lymphocytes. Bone marrow is found in the connective tissue interior of bones.
In a healthy person, the concentration of oxygen also called O₂ saturation in arterial blood is in the order of 97 and 100%, both at rest and during exercise.The concentration of oxygen in blood is a parameter that depends on proper respiratory function, and varies according to whether the blood is arterial or venous, where this percentage is lower.
Therefore, Without the skeletal system, the body could not carry oxygen in the blood. The given statement is true.

A. Storing energy
B. Forming a capsid
C. Providing insulation for the cell
D. Making up the cell membrane
Answers
This is because we know that the main function of lipids is to store energy. They also provide insulation for the cell because they make up the cell membrane. Therefore, we can use process of elimination to see that lipids do not form capsids.

What is an organism? Include examples for both plants and animals.
Answers
Answer:
Explanation:
En biología, se llama organismo o ser vivo a un individuo singular y diferenciado, compuesto por un conjunto de materia orgánica jerarquizada y especializada. Lo constituyen sistemas de transmisión y comunicación bioquímica, que le permiten conservar su equilibrio interno a la vez que intercambiar materia y energía con el entorno que lo rodea. Dicho en otras palabras, un organismo es una entidad viviente, dotada de la capacidad de nutrirse, crecer, reproducirse y morir.
Todos los organismos conocidos, con excepción de los virus, están formados por células, y poseen un metabolismo que les permite garantizar su existencia y dar pie a sus procesos biológicos a cambio de intercambiar energía con el medio ambiente. El fin último de todo organismo parece ser la reproducción, esto es, la perpetuación de su especie y la transmisión de su material genético (herencia).
Químicamente hablando, los seres vivos se distinguen de la naturaleza que los rodea en su composición casi exclusiva a base de carbono, hidrógeno, oxígeno y nitrógeno, es decir, a base de moléculas orgánicas, estructuradas de manera muy diferente a las moléculas inorgánicas de la materia inerte.
