Question 4 expressways have fewer collisions than highways because a fewer vehicles use expressways b speeds are slower c they are well designed and maintained

c they are well designed and maintained

Explanation:

The expressway is a fast and uninterrupted traffic lane. It is clear to any driver that there are fewer accidents on expressways than on urban roads, this is explained by the almost complete absence of intersections, the absence of traffic lights, the modern layout of these roads, which are the result of a well-structured project that maintains the expressways. .

However, since we know that speed directly influences the severity of the accident and knowing that we need to speed up the expressways even for safety reasons, since we have to keep up with the other vehicles, all we have to do is know some basic safety rules to navigate these roads without exposing our lives and assets to risk.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

the sun creates it's own light, also gives light and life to bunch of stuff like plants,animals,humans etc.photosyntesis is the process of making food which needs sun,water,nutrients etc.
