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: For the multiple choice the answers are B and C

Explanation: Just had this question in class

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:

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).

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.

Answer:

i think it's hydra but i'm not sure.

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.

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.

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.

Which of the following are sensory organs in the human body?

Choose: Eyes, ears, and nose

Dominant character:are always expressed when the connected allele is dominant,even if only one copy of the dominant trait exits.

Recessive character:are expressed only if both the connected allele are recessive.

Answer:

Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.

Explanation:

If some traits are absent or not expressed, but found in the parent, then the allele is said to be recessive.

Difference Between Recessive and Dominant Traits

DOMINANT

Dominant Trait Recessive Trait

Dominant allele is denoted by a capital letter

RECESSIVE

Recessive allele is denoted by a small letter

Answer:

Phospholipid bilayer

Explanation:

That is essentially the primary componenent of the cell membrane where phospholipids form two layers.

The energy released during respiration is stored in the form of compounds called ATP molecules. They are produced by the enzyme ATP synthesis which converts ADP to ATP. It is located in the membrane of the cellular structures called mitochondria.

Answer:

Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.

Answer:

Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury

The researchers prefer to use embryonic stem cell in medical research as Embryonic stem cells are able to differentiate into a wider range of call than adult stem cells.

A blastocyst, an early-stage pre-implantation embryo, is the source of embryonic stem cells, which are pluripotent stem cells. Four to five days after fertilization, human embryos reach the blastocyst stage.

The human blastocyst, an early stage of the developing embryo that lasts from the fourth to seventh day after fertilization, contains embryonic stem cells (ESCs) in its inner cell mass. In typical undeveloped turn of events, they vanish after the seventh day.

The ability to differentiate into cell types belonging to the three germ layers (ectoderm, endoderm, and mesoderm) is what is meant by the term "pluripotent." the three distinct types of tissue that are present during embryonic development and later combine to form the adult.
