Which best describes what is occurring in this population of squirrels? Number of Squirrels Entering and Leaving a Population after 1 Year Cause of change Number of squirrels Died from predation 2 Born 4 Immigration 10 Left to find food 3 Died from disease 8 Left to find a mate 3
Answer:
Explanation:
The population of squirrel is decreasing and this can be traced to the environment not being favorable for their growth and development.
Looking at the data generated,
Died from predation =2
Born=4
Immigration=10
Left to find food =3
Died from disease=8
Left to find mate=3
If all the squirrel did not abandon their habitat and they all live there a total of 2+4+10+3+8+3= 30 squirrel would have been present, but given that only 4 were born and that others left for another place the population is reduced to 4 and 26 squirrel gone this has lead to a reduced population.
Answer:
A
Explanation:
Population growth is decreasing.
What is the difference between mechanical weathering and chemical weathering?
Answer:
Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface.
Unattached earlobes is a dominant trait, E. A parent who is homozygous for unattached earlobes is crossed with a parent who is homozygous for attached earlobes. Which describes the genotypes of their offspring?
Answer:
Homozygous Dom and Homozygous recessive traits are both shown.
Look below for answer V
Explanation:
Considering that both are homozygous, that means that both traits are of the same kind.
Unattched earlobes is dominant, which means its sign would be (EE)
Attatched is the recessive, which means its sign would be (ee)
On a table, the genes would look this way-
EE EE
ee Ee Ee
ee Ee Ee
Since there is a dominant trait in all of the genes, the children would 100% have unattached earlobes.
(As a counter situation, if the unattatched was heterozygous, the chance of attatched to unattatched would be 50/50 as theres no dominant trait lurking)
I may be incorrect but i hope this helps!
The actual alleles that an organism possesses make up its genotype. The appearance or characteristic of an organism is known as its phenotype. A person would have detached earlobes if their genotype was Ee.
What are the Unattached earlobes genotype?The person who has free earlobes and is heterozygous has the genotype Ee and is capable of producing both the E and e alleles.
Punnett's squares are a good illustration of this. The person who has linked earlobes has the genotype ee and is only capable of producing e alleles.
All the genes have a dominant characteristic, therefore all the offspring would have detached earlobes.
Since there is no hidden dominant characteristic, (as a counter example, if the unattached was heterozygous, the risk of attached to unattached would be 50/50)

What is the number of this particle in a phosphorus atom?
Ap ex
Answer:
Fósforo
Símbolo P, número atómico 15, peso atómico 30.9738. El fósforo forma la base de gran número de compuestos, de los cuales los más importantes son los fosfatos. En todas las formas de vida, los fosfatos desempeñan un papel esencial en los procesos de transferencia de energía, como el metabolismo, la fotosíntesis, la función nerviosa y la acción muscular. Los ácidos nucleicos, que entre otras cosas forman el material hereditario (los cromosomas), son fosfatos, así como cierto número de coenzimas. Los esqueletos de los animales están formados por fosfato de calcio.
Cerca de tres cuartas partes del fósforo total (en todas sus formas químicas) se emplean en Estados Unidos como fertilizantes. Otras aplicaciones importantes son como relleno de detergentes, nutrientes suplementarios en alimentos para animales, ablandadores de agua, aditivos para alimentos y fármacos, agentes de revestimiento en el tratamiento de superficies metálicas, aditivos en metalurgia, plastificantes, insecticidas y aditivos de productos petroleros.
De casi 200 fosfatos minerales diferentes, sólo uno, la fluoropatita, Ca5F(PO4)3, se extrae esencialmente de grandes depósitos secundarios originados en los huesos de animales y que se hallan en el fondo de mares prehistóricos, y de los guanos depositados sobre rocas antiguas.
La investigación de la química del fósforo indica que pueden existir tantos compuestos basados en el fósforo como los de carbono. En química orgánica se acostumbra agrupar varios compuestos químicos dentro de familias llamadas series homólogas.
Esto también puede hacerse en la química de los compuestos de fósforo, aunque muchas familias están incompletas. La familia mejor conocida de estos compuestos es el grupo de cadenas de fosfatos. Las sales de fosfatos constan de cationes, como el sodio, junto con cadenas de aniones, como (PnO3n+1)(n+2)-, que pueden tener de 1 a 1 000 000 de átomos de fósforo por anión.
Los fosfatos se basan en átomos de fósforo rodeados en una disposición tetraédrica por átomos de oxígeno, el miembro más pequeño de la familia es el anión simple PO3-4 (el ion ortofosfato). La familia de las cadenas de fosfato se basa en hileras alternadas de átomos de fósforo y oxígeno en que cada átomo de fósforo permanece en el centro de un tetraedro de cuatro átomos de oxígeno. Hay también una familia estrechamente relacionada de fosfatos cíclicos.
Una característica estructural interesante de muchos de los compuestos del fósforo conocidos es la formación de estructuras tipo jaula. Ejemplos de estas moléculas son el fósforo blanco, P4, y uno de los pentóxidos de fósforo, P4O10. Las estructuras tipo red son comunes; por ejemplo, los cristales de fósforo negro en que los átomos están enlazados unos con otros.
En la mayor parte de sus compuestos, el fósforo está enlazado químicamente a cuatro átomos inmediatos. Hay gran número de compuestos en los que uno de los cuatro átomos está ausente y en su lugar hay un par de electrones no compartidos.
Hay también unos cuantos compuestos con cinco o seis átomos unidos al fósforo; son muy reactivos y tienden a ser inestables. Durante los años 60 y 70, se prepararon muchos compuestos orgánicos de fósforo. La mayor parte de estas estructuras químicas incluye tres o cuatro átomos enlazados al fósforo, pero existen también estructuras con dos, cinco o seis átomos unidos a cada átomo de fósforo.
Casi todo el fósforo utilizado en el comercio está en forma de fosfatos. La mayor parte de los fertilizantes fosfatados constan de ortofosfato diácido de calcio u otofosfato ácido de calcio muy impuros, Ca(H2PO4)2 y CaHPO4. Estos fosfatos son sales del ácido ortofosfórico.
El compuesto de fósforo de mayor importancia biológica es el adenosintrifosfato (ATP), que es un éster de la sal, el tripolifosfato de sodio, muy utilizado en detergentes y ablandadores de agua. Casi todas las reacciones en el metabolismo y la fotosíntesis requieren la hidrólisis de este tripolifosfato hasta su derivado pirofosfato, llamado adenosindifosfato (ADP).
Efectos del Fósforo sobre la salud
El Fósforo puede ser encontrado en el ambiente más comúnmente como fosfato. Los fosfatos son substancias importantes en el cuerpo de los humanos porque ellas son parte del material de ADN y tienen parte en la distribósforo que es conocida. Cuando el fósforo blanco ocurre en la naturaleza este puede ser un peligro serio para nuestra salud. El fósforo blanco es extremadamente venenoso y en muchos casos la exposición a él será fatal. En la mayoría de los casos la gente que muere por fósforo blanco ha sido por tragar accidentalmente veneno de rata. Antes de que la gente muera por exposición al fósforo blanco ellos a menudo experimentan náuseas, convulciones en el estómago y desfallecimiento. El fósforo blanco puede causar quemaduras en la piel, dañar el hígado, corazón y riñones.

Explanation:
A plant grows faster and fuller due to large amounts of fertilizer. If the plant cross-pollinates with another plant later, how will the use of fertilizer on the parent plant affect the plant’s offspring?
Answer:
The answer is "C" because nothing that your parents do, unless it directly affects/changes the gametes, will pass down to the offspring. Fertilizer is like food, how much your parents have eaten in their childhoods will have no effect on if you are under or over weight. (Unless their weight was by a genetic cause, that might have been passed on to you.)

Answer:
natural selection leads to evolution
Explanation:
Natural selection leads to evolution. Therefore, the correct statement is option A.
What is natural selection?Evolution is a result of natural selection. Natural selection is an evolutionary mechanism that rewards people with specific features that help them live and procreate more successfully than those lacking such traits. New species evolve as a result of an increase in the frequency of these favorable features in the population throughout time.
Natural selection is a major force behind evolution in this way. However, other processes, such genetic drift, gene flow, and mutation, can also lead to evolution.
Natural selection and evolution are separate but closely connected ideas. It is one of the mechanisms that propels evolutionary change through time; as such, it is a mechanism of evolution. It acts on the genetic variation present in a population, favoring traits that increase an organism's reproductive success in a given environment.
Therefore, natural selection leads to evolution.

Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy? hypertonic transport active transport passive transport dynamic equilibrium
Answer:
Passive transport
Explanation:
Diffusion is a passive mechanism of transport. Until the concentration is the same throughout the space, a single substance has a tendency to travel from an area of high concentration to an area of low concentration. You are aware of how compounds diffuse through the air.
What are the passive transport dynamic equilibrium?Chemicals move passively from a location of higher concentration to a region of lower concentration through a process called diffusion.
We discussed three passive transport techniques: osmosis, assisted diffusion, and diffusion, all of which are crucial for cellular operations. Although the precise mechanics powering each of these transportation strategies vary, they are all non-energetic.
Therefore, Passive transport is a phenomenon that happens naturally and doesn't require the cell to use energy to move.
