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:

The last woman scientist discovered one gene that is unique in human, and she called it an Eureka moment. How many letters are different in that gene if you compare the chimp version with the human version
Only one letter is different between the human gene and the chimpanzee gene.
What is a gene?
A gene is a term to refer to the molecular unit of genetic inheritance that is composed of deoxyribonucleic acid, that is,
A sugar group. A phosphate group. A nitrogenous base. Guanine (G) Cytokine (C) Thymine (T) Adenine (A)
Man and chimpanzee share 99% of their genes. However, there are important genetic differences for us to be a different species from chimpanzees. Well, the change of a single nitrogenous base and differentiates the gene of a chimpanzee from the gene of a human.

The air we breathe is mostly a mixture of oxygen and nitrogen. How do air molecules change when they reach altitudes above 100 km?
I need to make sure the answer I have is right.
As you increase in altitude, there are fewer air molecules. Due to the lower amounts of air molecules, the atmospheric pressure decreases causing the air to be harder to breath in.

First image shows a stationary organism whereas the second image indicates predator.
The first picture represents a leaf structure which is a part of plant and we know that plant is a stationary organism means it can't move from one place to another so that's why it is called a stationary organism.
While on the other hand, the second picture represents predator due to the presence of sharp teeth which helps the predators in catching and tearing of prey so we can conclude that first image shows a stationary organism whereas the second image indicates predator.

What distinguishes an acute disease from a chronic disease?
What is the difference between them
Answer:
Acute illnesses generally develop suddenly and last a short time, often only a few days or weeks. Chronic conditions develop slowly and may worsen over an extended period of time—months to years.
Acute diseases refer to the medical condition that occurs suddenly and lasts for a shorter period of time. Chronic diseases develop slowly in our body and may last for a lifetime. Chronic diseases are sometimes fatal.

The equator has light closer to 90 degrees, at the poles the angle is lower than 90 degrees. Use this information and refer to the data from Table B to explain why the tropics (near the equator) are hotter than the arctic region (north/south poles). Be sure to include data from Table B in your answer.
The temperature at tropic region is warmer than the polar temperatures due to angle of the sun.
The tropics which is located near the equator are hotter than the arctic region i.e. north and south poles because the sunlight falls directly on the tropic regions at 90 degrees while on the other hand, the sunlight falls on the poles not directly and form angle lower than 90 degrees.
The amount of solar energy in a given area is greater at the equator and tropic regions than in an equal area at the poles so that's why the temperature at tropic region is warmer than the polar temperatures.

Which definition is the best for “semipermeable membrane”?
It is a barrier that prevents materials from moving from one side to the other.
It is a barrier that allows materials to move freely from one side to the other.
It is a barrier with tiny openings that let some, but not all, materials pass through.
It is a barrier that helps materials move from one side to the other.
Answer:
C
Explanation:
Semi means partly
permeable means allowing liquids or gases to pass through it
Semipermeable means allowing some, but not all, liquids or gases to pass through it.
Answer:
c) It is a barrier with tiny openings that let some, but not all, materials pass through.
Explanation:
The prefix "semi-" means "some; partially". "Permeable" means "allow to pass through". Using your knowledge of the purpose of the membrane and the meaning of the word "semi-permeable", you would use context to come to the conclusion that the correct answer is c) It is a barrier with tiny openings that let some, but not all, materials pass through.
HELP!!! WILL GIVE MAX POINTS!! Doing a Lab Report on Natural Selection about beans. For example 20 dark red beans and 35 light red beans (kidney beans) Sample Response: When the volcano erupted, the dark red walking beans were easier to see.

Answer:
During the days four through six the population of the dark red beans changed. The change was negative meaning that there was less dark red beans that light red beans. This happened because it was harder to see the light red beans because the color of the air changed. In result of that the zocco ate mostly dark red beans.

The crust provides raw materials necessary for life. C. The crust allowed the formation of fossil fuels. D. The rock cycle recycles sedimentary rocks formed from animal shells. Please select the best answer from the choices provided A B C D.
The statement 'the crust provides raw materials necessary for life' best describes the interaction between Earth's crust and organisms. It is fundamental for the biogeochemical cycles.
Earth's crust consists of a tiny layer on the outside of Earth that accounts for less than one percent (1%) of Earth's volume.
The Earth's crust is essential in biogeochemical cycles that support the continuity of life on the Earth planet.
These biogeochemical cycles include, among others, the carbon cycle, nitrogen cycle, phosphorous cycle, etc.
