The polypeptide encoded by the glucose carrier gene has a signal sequence. As a result, the ribosome and the polypeptide that is
olganol [36]

Answer:

The correct words for the three blanks are as follows:

1. Endoplasmic reticulum. 2. Golgi apparatus. 3. Facilitated diffusion.

Explanation:

During the translation stage of protein synthesis, signal sequences are either attached or excluded from a synthesized protein in order to indicate the right location it should be sent to. Proteins that possess signal sequences are usually sent to the endoplasmic reticulum, where they will be folded into their right shapes. From the endoplasmic reticulum the proteins are then transported into Golgi apparatus via membrane vesicles. In the Golgi apparatus, proteins undergo their final modifications before they are transported to their final destinations. The final destination of glucose carrier proteins is the plasma membrane, where they help glucose molecules to enter the cell via facilitated diffusion.

Some fruit flies have orange eyes and others have red eyes.
Burka [1]

Answer:

not 100% sure but

Explanation:

might be because each fruit fly has a different eye color because offspring from parents will have different eye color. or it might be from some sort of mutation that happened, that might be why they still have the gene to orange eyes. or red eyed fruit flys(or fly) migrated into a orange eyed populating and had offspring like that, that would also explain why red eyed fruit flys have the orange eyed gene.

again not 100% sure

but I hoped it helped a little

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six
Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

Why are the epidermis layers of the leaf coated in a waxy cuticle
Andrews [41]

Answer:

prevent excessive loss of water

Explanation:

The epidermis is a single layer of cells covering all plant organs. The epidermal cells are elongated in the direction of stem length and flattened. They have no chloroplast and their outer walls are covered by a waxy cuticle that prevents excessive loss of water through evaporation. The cuticle also protects the inner tissues from infection and mechanical injury.
