Not very sure, but this is probably because the stain is much more dried up and already sticked onto the surface, rather than the paper towel that simple brushed by it for the couple of seconds used in attempt to wipe the stain.
Please mark me brainliest so I can become a Virutoso, thank you! :)
Answer:
The correct answer is - B. Woodchucks hibernate to survive the winter.
Explanation:
Many mammals such as groundhog or also known as woodchucks hibernate during winter in order to survive winter. Hibernation is the process or state of minimal activity during a particular time of the year characterized by low body temperature, slow heart rate, and low metabolic rate.
Woodchucks are become less active and remain in their burrow and seen very little during the winter and stay like this till late winter or early spring.
Explanation:
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.
Disaccharide is a simple compound which is made up of two molecules of sugar which include glucose and galactose.
These glucose molecules form a crystalline water soluble compound.
This is found in food like sucrose and lactose. This is composed of four chemical grouping of carbohydrates.
Chocolates are also considered as disaccharide compound due to presence of sugar.
