Greg's mom has bushy eyebrows. Greg's dad has a large nose. Greg has bushy eyebrows and a large nose. Which statement correctly

explains what structures of the cell are responsible for the inheritance of Greg's traits?
A) Facial traits like nose size and eyebrow size are sex linked traits so they are located on the X and Y chromosome. Heredity is the passing of sex linked traits only.

B) Each gene is located inside the ribosome of each cell and when it undergoes DNA synthesis, traits are passed from one cell to another. Heredity is the passing of traits during DNA synthesis.

C) Each gene is located on a section of DNA of the chromosome. Inside each cell, this DNA contains instructions for each person. Heredity is the passing of these genes from Greg's parents to him.

D) Each trait that Greg inherits from his parents are inherited from his parents, including his big nose and his bushy eyebrows. These traits are produced during cellular respiration. Heredity is the passing of traits during cellular respiration.

<span>C is the correct answer. A is not correct because we do not know if nose size and eyebrow size are sex linked traits - nothing in the question suggests this. Moreover, heredity is not just the passing of sex linked traits. Heredity also includes traits that are not sex linked. B is not correct because genes are not located inside ribosomes. Genes are located on DNA. DNA synthesis does not cause heredity. DNA synthesis is the replication of the DNA prior to cell division. D is not correct. C is the correct answer because genes are located on DNA that is contained in a chromosome. DNA contains information about proteins. The information is hereditary, or passed down, from parent to child.</span>

What is missing from the venn diagram PLEASE HELP!!
alukav5142 [94]

Answer:

Esta es mi respuesta quizá hay respuestas que difieran de la mía .

Bueno tus diagramas son mas de euler que de venn, por que les falta el conjunto universo. pero bueno para lógica matemática nos sirven ambos.

A ver:

Para representar por Compresión, expresamos la principal característica global que define a los elementos del conjunto con simbología o escritura.

Para expresar por Extensión se ponen todos los elementos del conjunto.

Para tu ejercicio:

a)

Extensión

A={ 1 ; 4 ; 5 ; 12 }

B={4 ; 8 ; 12}  

Compresión

x / x ∈ AUB ⇔ x∈A  ó  x∈B  

b)  

Extensión

A={10,5,14}

B={5 ; 14}

Comprensión

x / x ∈ A ⇔ B⊂A ⇒ x ∈ B  

c)

Extensión

A={8 ; 9}

B={5 ; 15}

Comprensión

x / x ∈ A ⇔A⊄B

x / x ∈ B ⇔B⊄A

bogdanovich [222]

In a hen house, the length of daylight is prolonged by using indoor lighting. the stimulus for egg laying is

(a) food

(b) warmth

(c) light

(d) amount of water.

The correct answer is option (c) light.

Light is found to have a significant effect on egg laying by hens in the hen houses or poultry. Photoperiod is the length of the time within a day to which the hens are exposed to sunlight or artificial source of light. Egg production is reduced if the light intensity and duration is reduced. A peak production of hens is observed with the photoperiod is lengthened or a longer photoperiod.

Natural day light exposure to hens results in the production of not more than 40 eggs. Whereas, a prolonged day light of 12- 14 hours by indoor lighting increases the number of eggs layed to around 60 eggs. Thus, the stimulus for egg laying is the light.

Thus, In a hen house, if the length of daylight is prolonged by using indoor lighting, the stimulus for egg laying is light.

ahrayia [7]

Answer:

The enzyme would be deactivated

Explanation:

If a meat coated with tenderizer is placed in a refrigerator, the cold environment of the refrigerator would deactivate the enzyme.

<em>Enzymes are generally sensitive to temperature with high temperature capable of destroying the polypeptide bonds that hold the amino acids together thus denaturing their proteinous nature.  At low temperatures, the molecules of the enzyme move less and less until the enzyme becomes deactivated.</em>
