Answer: Option C) Animal

The cell wall is tough, flexible and fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides cells with structural support and protection. All BUT ONE type of organism has cells with cell walls. That is an animal

Explanation:

One distinguishing feature of animal cells compared to other living cells is the absence of cell wall.

However, the animal cell possess a cell membrane, with which it regulates substances entering or leaving the cell, and also provide protection and mechanical support for the cell against foreign invaders such as pathogens.

Factors that determine the rate of stream erosion-

➡️ Rainfall (more rain more erosion). ✔️

➡️water velocity ✔️

➡️shape, size and depth of channel ✔️

➡️stream capacity to transport eroded material, and the nature of the material being transported✔️

➡️Gradient (Steepness or slope) ✔️

➡️Discharge (Amount of water carried at a given time) ✔️

➡️Load (The materials carried by a stream)
Rainfall (more rain more erosion). ✔️

➡️Slope (the steeper the slope the faster the water will flow) ✔️

Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine
vova2212 [387]

Within a double-stranded DNA molecule, adenine forms hydrogen bonds with thymine, and cytosine forms hydrogen bonds with guanine This signifies <u>determining the type of protein produced</u>

DNA's unique structure enables the molecule to copy itself during cell division. The double-helix shape allows for DNA replication and protein synthesis to occur. Each of the two strands in double-stranded DNA acts as a template to produce two new strands.

Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules: adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G).

Glaucoma is a leading cause of blindness. Studies have linked a common form of glaucoma to three genes and more than 20 genetic
NeX [460]

Answer: The correct answer is -

d) a dominant trait that depends on the presence of only one of many dominant alleles.

Glaucoma is an autosomal dominant trait, meaning that presence of single copy of the defective gene is enough to cause the disease.

It corresponds to a group of diseases, which cause damage in the optic nerve, leading to loss of vision and if not treated, it ultimately leads to blindness.

Thus, option D) is the right answer.
