Explanation:

Epimysium is a sheath of fibrous elastic tissue surrounding a muscle.

It is a layer of dense irregular connective tissue which ensheathes the entire muscle and protects muscles from friction against other muscles and bone

Energy from the sun comes from fusion. what happens during this reaction

OverLord2011 [107]

Hydrogen atoms are compressed together by the enormous gravitational force of the sun, causing them to fuse int a helium atom (which is heavier than hydrogen), subatomic particles and enormous release of atomic energy. The attached picture shows the sequence of the main reaction at the core of the sun.

Answer:

1) aa- affected

2) Aa- unaffected carrier

3) aa- affected

4) aa- affected

5) Aa - unaffected carrier

6) Aa- unaffected carrier

7) aa- affected

8) aa- affected

9) Aa- unaffected carrier

10) aa- affected

11) Aa- unaffected carrier.

This trait is <em>recessive</em>.

The F1 generation has a 50/50 chance of having unaffected offspring.

Explanation:

1) Given

2) Some of the offspring have the trait, and they're not affected, so they have to be a carrier

3) The box is shaded in so they have to have the trait, which means they have to have the same gene pattern as the other affected person (#1)

4) They are also shaded in, so they have to have the trait

5) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

6) Same reasoning as #5

7) This is shaded in, the box has to have the trait

8) Shaded in = has the trait/affected

9) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

10) Shaded in = has the trait/affected

11) Since the parents either have the trait or are carriers, if they're not affected they have to be a carrier

Since the trait is displayed when the people have two lowercase letters (aa), and people can be unaffected and carriers, (Aa), this trait has to be recessive.

If you make a Punnett Square, you will see that half of the offspring can result in an Aa, while the other half can result in an aa, meaning there's a 50/50 chance of the offspring of the F1 (first) generation will have the trait.

gladu [14]

Answer:

esta es una expresión de admiración ante la belleza de los mecanismos evolutivos

Explanation:

El concepto de evolución como mecanismos naturales que está actualmente en boga fue originalmente planteado por Charles Darwin en su celebre publicación "El origen de las especies" (1859). La teoría de la evolución de Darwin está basada en la idea que las especies cambian constantemente con el tiempo a través del proceso de selección natural. Este mecanismo es responsable de la inmensa biodiversidad biológica observada en la naturaleza, la cual incluye la evolución de las especies, poblaciones y organismos individuales. Desde una perspectiva biológica, es imposible no quedar fascinado ante la naturaleza y contemplación de los procesos evolutivos.

An organism is described as 2n = 48.A) How many chromatids per chromosome are in one meiotic cell during prophase 2?B) How many

Alex

Answer:

A) 48

B) 96

C) 48

D) 48

Explanation:

Attached is a table summarizing the number of chromosomes and chromatids in the different stages of mitosis and meiosis in humans who are described as 2n = 46.

For the organism which is described as 2n = 48, substitute 46 in the table for 48 to get the appropriate figures.
