Answer:
The scientific method is a system of exploring the world around us, asking and answering questions, and making predictions. Scientists use the scientific method because it is objective and based on evidence. A hypothesis is fundamental to the scientific method. A hypothesis can take the form of an explanation or a prediction. There are several ways to break down the steps of the scientific method, but it always involves forming a hypothesis, testing the hypothesis, and determining whether or not the hypothesis is correct. If the hypothesis is rejected, this does not mean the experiment was a failure. In fact, if you proposed a null hypothesis (the easiest to test), rejecting the hypothesis may be sufficient to state the results. Sometimes, if the hypothesis is rejected, you reformulate the hypothesis or discard it and then go back to the experimentation stage.
The process of scientific learning refers to the various steps via which one can examine and study our environment to understand it. Once understanding or know-how is achieved, then technology is said to have advanced further.
It starts with making observations. Now because of the limitation of our senses, it is important not to jump to conclusions. The next step is to form a hypothesis based on the observation madeWhen you have arrived at a hypothesis, you can now carry out a controlled experiment where you collect further data and reach conclusions based on the experimentIf the hypothesis is in line with your observation, you publish resultsIf the hypothesis is null, you also publish results, then review your hypothesis and repeat the experimentAll the above require consistent documentation at each stage.

Which of the following is not one of the steps of the water cycle?
A. Condensation of water vapor into clouds.
B. Throughflow of underground water back to the ocean.
C. Respiration of water into the atmosphere.
D. Transpiration of water into the atmosphere.
The option that is not one of the steps of the water cycle includes options C(Respiration of water into the atmosphere)
and D(Transpiration of water into the atmosphere).
Water cycle can be defined as the constant flow or movement of water through earth, atmosphere and the oceans either in liquid states or vapour.
The four main steps of water cycle includes:
EvaporationCondensationprecipitation and Collection (this leads to formation of underground water which gradually flows back into the oceans).In nature, water circulates mainly within the abiotic (non-living) environment; only a small proportion recycled through living organisms.
Therefore respiration and transpiration which occurs through living organisms doesn't form the major steps of water cycle, hence the correct option is C (Respiration of water into the atmosphere) and D (Transpiration of water into the atmosphere).

5. 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³ (electrones de valencia) Grupo: 15 Periodo: 4
Explanation:
La configuración electrónica de los elementos es la disposición de todos los electrones de un elemento en niveles y subniveles de energía (orbitales).
Hay 7 niveles de energía, numerados del 1 al 7, y en los que los electrones se distribuyen, lógicamente, en orden según su nivel de energía. Los electrones con menos energía girarán en el nivel 1. Cada nivel se divide en subniveles. Estos subniveles en los que se divide cada nivel pueden ser hasta 4. Estos 4 subniveles se denominan: s, p, d, f. En el subnivel s solo puede haber un máximo de 2 electrones, en p puede haber un máximo de 6 electrones, en el subnivel d 10 electrones y finalmente en el subnivel f puede haber un máximo de 14 electrones.
Por otro lado, los electrones de valencia son los electrones que se encuentran en la última capa electrónica (denominada orbitales de valencia) y tienen muchas posibilidades de participar en una reacción química.
En la tabla periódica, en cada período aparecen los elementos cuyo último nivel de su configuración electrónica coincide con el número del período, mientras que en cada grupo aparecen los elementos que presentan el mismo número de electrones en el último nivel ocupado o capa de valencia. Entonces:
1. 1s² Grupo: 18 Periodo: 1
2. 1s²2s²2p⁶3s¹ Grupo: 1 Periodo: 3
3. 1s²2s²2p⁶3s²3p⁶4s² Grupo: 2 Periodo: 4
4. 1s²2s²2p⁶3s²3p⁶4s²3d¹ (electrones de valencia) Grupo: 3 Periodo: 4
5. 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p³ (electrones de valencia) Grupo: 15 Periodo: 4

Answer:
Cancer and Arthritis
Explanation:
Some causes of cancer include smoking, obesity, and lack of nutrition. Cancer is diagnosed using a biopsy. A biopsy is a procedure in which the doctor removes a sample of tissue. A pathologist looks at the tissue under a microscope and runs other tests to see if the tissue is cancer. Some treatments for cancer include Chemotherapy, surgery, Radiation therapy, and bone marrow transplant.
The most common cause of arthritis is usually if your family has a history of arhritis. It is usually diagnosed with an x-ray or a blood test. Treatment includes Painkillers, physical therapy, and exercise.

All of its cells are electrically connected via gap junctions. All of its cells are sparsely distributed in the extracellular matrix.
Answer:
Connective tissue is a group of tissues in the body that keep the body and its organs in shape while also providing cohesion and internal support.
All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.
What is connective tissue?
Tissue that sustains, protects and provides structure to other tissues and organs in the body. Connective tissue also stores fat, permits the movement of nutrients and other substances between tissues and organs, and allows the repair of damaged tissue. Connective tissue exists created up of cells, fibers, and a gel-like substance.
Connective tissue is discovered in between other tissues everywhere in the body, including the nervous system. The three outer membranes (the meninges) that surround the brain and spinal cord exist composed of dense inert connective tissue.
Connective tissues bind systems together, form a framework and support for organs and the body as a whole, store fat, transport substances, defend against disease, and assist restoration of tissue damage.
Hence, All of its cells exist sparsely distributed in the extracellular matrix is the best description of connective tissue.

Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes closest to explaining the basis for placing these organisms in different taxa, well before relevant data from molecular systematics became available?
Answer:
Due to other differences.
Explanation:
The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.

Why ulva is not placed in kingdom plantae
Answer:
Because Ulva is an algae. Algae belongs to kingdom Protista.
Explanation:
Ulva is a Macroalgae because it's not microscopic.
Macroalgae is not considered as a plant due to their structure. Macroalgae do not have specialized organs and tissues, and they are not vascularized. They also do not have the capacity to form a structure with flowers, leaves, roots or a stem.
use numbers to arrange the events of a demographic transition in order in which they occur
is this correct?
(DTM) is defined by a country's death rate dropping quickly while its birth rate staying high. Because of this, a nation in Stage 2 will show an increase in its general population—not because the birth rate is rising, but because births outnumber deaths.
What are the different events of a demographic transition?The demographic transition model was initially proposed in 1929 by demographer Warren Thompson. The four stages of the paradigm are pre-industrial, urbanizing and industrializing, mature and post-industrial.
Stage 1: Slow population growth is caused by high birth and mortality rates. Stage 2: While the birth rate stays high and the death rate declines, population growth accelerates. Stage 3: Population growth slows as the birth rate starts to decline.
Therefore, 1,4,2 and 3. It is correct events of a demographic transition in the order in which they occur.
