What are 3 characteristics of a solid?

Biology
1 answer:
STALIN [3.7K]3 years ago
8 0

Liquids will flow and fill up any shape of container. Solids like to hold their shape. In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want.

Redacta un escrito dónde expliques como está formado(un ecosistema), menciona ejemplos y como sigue una estabilidad por el equil
IceJOKER [234]

Answer:

Un ecosistema esta formado por facotres abioticos y bioticos.

Los factores bioticos son aquellos que presentan signos vitales, es decir que cumplen con la vida, metabolismo, respiracion, entre otras funciones vivas.

Los factores abietos son aquellos que no tienen vida pero con los que los factores bioticos intercambian energia, un ejemplo de esto son las rocas, los vientos, los sedimentos, la tierra fertil.

Los factores bioticos serian los organismos vivos como los animales, que al funcionar como sistemas abiertos de intercambio de energia constante mantienen un equilibrio fisico biologico con los factores bioticos.

Explanation:

Los ecosistemas cumplen con una cadena que no debe romperse ni faltar ningun eslabon, si esta continuidad se interrumpe con la extincion de una especie como animal o vegetal el ecosistema variará, y cambiara toda su conformacion.

Es un conjunto de factores bioticos y abioticos en armonia que se complementan e intercambian energia entre si de manera ordenada en eslabones, si uno de estos eslabones se rompe, se extingue, o se modifica por intervencion del hombre u otros factores TODO el escosistema se verá modificado o afectado.

Which statement describes the offspring of the Fı generation when crossing a pea plant that is true breeding for green seeds wit
alukav5142 [94]

The offspring will inherit one allele from each parent.

<h3><u>Explanation</u>:</h3>

The genetic crossing experiments lead to the formation of different hybrids which has several characters unlike their parents. Here the parents are homozygous.

One of the parent is homozygous yellow with respect to seed colour. So genetic combination of the parent will be YY.

The other parent is homozygous green with respect to seed color. So genetic combination of the parent will be yy.

Now as they are crossed the offsprings will have genetic combination of Yy.

This is seen that the offsprings carry one allele from both the parents.

How might you alter a trna so that it inserts an alanine into a polypeptide for which a lysine is coded?
castortr0y [4]
TRNA stands for transfer-RNA which is used in the process of protein synthesis or translation. tRNA is a unique clover leaf like structure that has 4 arms- amino acid acceptor site (acceptor arm), D loop, T psi C loop and anticodon loop. It also has a small variable loop. The anticodon loop consists of a sequence of 3 bases that is complementary to the 3 bases present of mRNA to be translated. A tRNA for alanine will have an anticodon for alanine while a tRNA for lysine will have an anticodon for lysine. For a tRNA to insert an alanine in place of lysine in a forming peptide, the anticodon and the amino acid acceptor site should be altered so that it accepts lysine in place of alanine and add it to the growing polypeptide.
