The inability to access memories formed, or difficulty in retrieving them, before brain damage or injury is called a Retrograde Amnesia
It is caused by impairment to the memory-storage areas of the brain. This type of damage can result from a distressing injury, a serious illness, a seizure or stroke, or a degenerative brain infection. It can be temporary, permanent, or get worse over time depending on the cause. With this type of amnesia, memory loss typically involves facts instead of skills. For instance, a person might forget if he owns a car, what make and model it is, or when he bought it, but he will still know how to drive.
Answer:
We live in an era of unprecedented road and highway expansion — an era in which many of the world’s last tropical wildernesses, from the Amazon to Borneo to the Congo Basin, have been penetrated by roads. This surge in road building is being driven not only by national plans for infrastructure expansion, but by industrial timber, oil, gas, and mineral projects in the tropics.
Few areas are unaffected. Brazil is currently building 7,500 kilometers of new paved highways that crisscross the Amazon basin. Three major new highways are cutting across the towering Andes mountains, providing a direct link for timber and agricultural exports from the Amazon to resource-hungry Pacific Rim nations, such as China. And in the Congo basin, a recent satellite study found a burgeoning network of more than 50,000 kilometers of new logging roads. These are but a small sample of the vast number of new tropical roads, which inevitably open up previously intact tropical forests to a host of extractive and economic activities.

Answer:
23,46
Explanation:
because a gamete is a sex cell that contains half of the genetic material (haploid) as a normal body cell. So in humans, instead of having 23 pairs of chromosomes, a gamete only contains 23 singular unpaired chromosomes. So if you also multiply it by 2 you would get 46
The Himalayan rabbit's environment entirely determines the color of its coat.
<h3>How does the environment affect the coat color on the fur of a Himalayan rabbit? </h3>
The color of newborn Himalayan rabbits is either white or light grey. Beginning at the age of four weeks and ending at six months, coloring the coat is a process. The temperature of the environment affects the color of the coat, which grows darker in colder climates and lighter in warmer ones. The Himalayan rabbit's hair turns black when it is subjected to subfreezing conditions. That area's fur finally turned black. The rabbit's newly grown fur will be black in color if the white fur is removed and the animal is kept at a low temperature. Considering this, it is clear that temperature affects the expression of genes that control this organism's fur color.
