Answer:
1). B). Asparagine-glycine-tyrosine
2). B). Prophase I
Explanation: Exchange of chromatid segments between non-sister chromatids of homlologous chromosomes is called crossing over. It occurs in meiosis I.
3). C). 1 pair of sex chromosomes and 22 pairs of autosomal chromosomes are pictured
Explanation:
Male = 22A + XY
Female = 22A+XX
4). D). They’re the main site of photosynthesis in autotrophs
Explanation:
Chloroplast composed of a liquid-filled space known as stroma. They are found in plant cells. They are full of flattened stacks of membranes called thylakoids.
5). C). Electron transport chain.
Explanation:
Glycolysis= 2 ATP
Kreb’s cycle = 2 ATP
Electron transport chain = 32 ATP
6). B). Store
Explanation: The main role of DNA in the cell is the long-term storage of information.
7). 7). D). The body failing to respind to signals that slow the cell cycle.
8). A). Exposing a plant to a higher light intensity
9). B). Telophase
Explanation: Nuclear envelope disappears in prophase and reappears in telophase.
10). D). Anaphase II
Explanation:
Homologous chromosomes move towards to opposite poles in meiosis I. Sister chromatids move towars opposite poles in anaphase II

The laws of conservation of momentum and conservation of energy are used to derive the equation for the muzzle velocity. Theory The ballistic pendulum has historically been used to...
Procedure: Fire a practice shot. Locate the landing point on the floor then secure a piece of white paper to the floor (centered about the landing point). Cover the sheet with a piece of carbon paper and tape it down. 1. Shoot the ball at least 5 times. Take care not to disturb the position of the launcher during the shots. 2. Measure the vertical height H of the projectile launcher from the floor. (Use a plumb bob determine the...

Problem (1) (40 points) A pendulum consisting of a ball of mass m and a massless string of length L 5.00 m is released from an angle of a 69 88 shown in the figure and strikes a block of mass M 2m. The block slides a distance D before stopping under the action of a constant friction force with the frio- tion constant μ": 0.50. The ball rebounds to an angle of Hints: Take g= 10 m/?. sin 16"...
THE EXPERIMENT The speed "." of a ball as it leaves the spring gun will be measured by projecting the ball horizontally (0-0) from a table top at a distance H above the floor. The gun is then elevated at a known angle 8. The position of the target is calculated using the measured value of v. calculated time of flight, and the equations of motion. A successful prediction with the projectile hitting the target means that the following concepts...
was trying work on this homework but can’t seem to get it right the ball and the pendulum cup have the same velocity after the collision. As is the case with any collision, total momentum is conserved (unchanged). Using conservation of momentum, write down an equation for Vealefore in terms of the velocity of the hall together with the pendmcu ( d the mass of the al and that of the cup (meup). ball before= Using conservation of energy between...
Need help With Analysis questions. Ballistic Pendulum Lab In this lab, you will explore conservation of Energy and Momentum in an inelastic collision between a projectile and a cardboard box suspended from a string. In particular, you will see that the transfer of linear momentum is easily accounted for in an inelastic collision, but the transfer of kinetic energy is not easy to measure directly. This is because Kinetic Energy in collisions transfers to vibrational, acoustic, and potential energy. Once...
Virtual Lab: Ballistic Pendulum Introduction The ballistic pendulum was invented by Benjamin Robins in 1742 as a device mainly designed to accurately measure the speed of fast traveling projectiles (bullets or cannon balls), relying only on measurements of mass and distance, without measurements of time. Knowing the mass of the projectile, estimates of its momentum and kinetic energy could also be made. Although the ballistic- pendulum method has lost its practical importance to more modern methodologies, it was used for...

1. A pole is held vertically by attaching wires at a height of 13.4 m above the ground. The other end of each wire is anchored in the ground at a distance of 9.54 m from the base of the pole. The pole makes a right angle with the ground. What is the length of each wire? 2. A bug crawls 2.25 m along the base of a wall. Upon reaching a corner, the bug's direction of travel changes from...
