Answer:

Los virus son más pequeños y no son células. A diferencia de las bacterias, necesitan un huésped como un humano o un animal para multiplicarse.

Las bacterias son organismos vivos unicelulares. Tienen una pared celular y todos los componentes necesarios para sobrevivir y reproducirse. Los virus no se consideran "vivos" porque requieren una célula huésped para sobrevivir a largo plazo, para obtener energía y para reproducirse.

Los virus son más pequeños que las bacterias. De hecho, el virus más grande es más pequeño que la bacteria más pequeña. Todos los virus tienen una capa proteica y un núcleo de material genético, ya sea ARN o ADN. A diferencia de las bacterias, los virus no pueden sobrevivir sin un huésped. Solo pueden reproducirse uniéndose a las células. En la mayoría de los casos, reprograman las células para crear nuevos virus hasta que las células explotan y mueren. En otros casos, convierten las células malignas o cancerosas.

Which of the following is a physical adaptation for the underlined animal?
ale4655 [162]

Answer:

Physical adaptations do not develop during an individual animal's life, but over many generations.

When a phosphate group is removed from an ATP molecule, energy is......................
Gnoma [55]

Answer:

Released.

Explanation:

The bonds between the phosphates in ATP are very high energy, meaning that the bonds really really want to break because phosphates don't like being so close to each other.  When the bonds do break, a ton of energy is released (think of it like a celebration that they aren't so close anymore).

In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilitie
kaheart [24]

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:

1. dominant parent and recessive parent

2. heterozygous parents

Answer:

1. dominant parent and recessive parent:

dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.

so,

 L    L

l  Ll   Ll

l  Ll   Ll

so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.

2. heterozygous parents

In this case, parents have Ll genotype and gametes would be L and l for each parent so,

    L    l

L   LL  Ll

l    Ll    ll

In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:

3/4 = 75%
