1. Luca made the following chart for Earth's four basic movements, what needs to be correct on his chart? Rotation Speed Revolution Speed Solar System Speed Milky Way Speed
0.3 miles/sec
18.5 miles/sec
370 miles/sec
150 miles/sec

The rotation speed and revolution speed should be switched

The revolution speed and solar system speed should be switched

The rotation speed and Milky Way speed should be switched.

The solar system speed and Milky Way speed should be switched.

The solar system speed and Milky Way speed should be switched.

Explanation:

The speed of the Earth is with respect to how it moves around it's own axis (rotation speed), the Sun (revolution speed), solar system (solar system speed), and the milky way galaxies (milky way speed) etc.

According to this question, Luca made a chart for this Earth's four basic movements. The chart with their respective speed are as follows:

Rotation Speed - 0.3 miles/sec

Revolution Speed - 18.5 miles/sec

Solar System Speed - 370 miles/sec

Milky Way Speed - 150 miles/sec

Luca, however, made a mistake in his chart.

- The rotation speed of the Earth around its axis is correctly 0.3miles/sec

- The revolution speed of the Earth around the sun is correctly 18.5 miles/sec

- The solar system speed of the Earth i.e. around the solar system is about 150miles/hour

- The milky way speed of the Earth i.e. around local group of galaxies is about 370miles/hour.

Based on the comparison of Luca's chart and correct speed illustration, THE SOLAR SYSTEM SPEED AND MILKY WAY SPEED SHOULD BE SWITCHED.

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.
