Answers

Answer:

The answer is Diploid number of Chromosomes, Haploid number of Chromosomes and Gamete Cells.

Explanation:

Meiosis is one of the forms of cell reproduction, this process is performed in the gonads for the production of gametes (haploid sex cells). Meiosis is a process of cell division in which a diploid cell (cells that have a double number of chromosomes) experiences two successive divisions, with the ability to generate four haploid cells.

Photosynthesis is a process in which _______ energy is converted to _______ energy.

Answers

Photosynthesis is a process in which light energy is converted to chemical energy.

Organisms, such as plants, that carry out photosynthesis absorb light from the Sun and, through a series of chemical reactions, produce sugar (glucose) molecules. These sugar molecules may be stored by the photosynthetic organism, or the chemical bonds in the sugar can be broken down by the organism to release energy for its life processes.

Answers

Hi There! :)

Based only on their anatomy rank gorillas bears chimpanzees and mice from most recent common ancestor with humans to least recent common ancestor

The animal that would have the most recent common ancestor with humans is the one that is physically most similar to humans. So we start with 

Chimpanzee
Gorilla
Bear
Mice

Mice are the least similar to humans among all of those so they would have the least recent common ancestor with us

How is vascular tissue arranged in dicot stems?A. in bundles in a ring
B. in randomly arranged bundles
C. in bundles near the outer edge
D. in a cross shape within the stem

Answers

The arrangement of vascular bundles in dicot stem is in the form of bundles in a ring.

Vascular bundles are the conducting tissues of the plant body. Their arrangement is quite different in monocots and dicots.

The vascular bundle in dicots are more complicated than that of monocots and arranged in the form of rings. They are designed in such a way that pits are concentrated at the core of the stem rather than being scattered throughout the plant.

In bundles in a ring is how a vascular tissue is arranged in dicot stems. 

Your answer is A. 

Scientists were motoring a meteor headed toward earth. It moved off course , but some pieces of rock entered the earths atmosphere . Which atmospheric layer protected the earth against the danger of the rocks ? A.the troposphere B.the stratosphere C.the mesosphere D.the thermosphere

Answers

The correct option is C.

The atmosphere is made up of five different layers, which are: exosphere, thermosphere, mesosphere, stratosphere and troposhere. The farthest layer is the exosphere while the nearest one to the earth surface is the troposphere. Each of these layers have their specific functions. The mesosphere is the one that is responsible for protecting the earth surface from meteors and asteroids. The mesosphere functions by burning up the greater parts of these substances before they enter the earth surface.

The answer is C. The atmospheric layer that protects the Earth against danger of the rocks is the mesosphere. This layer is above the stratosphere. Meteors are rocks from the space that enter the atmosphere. Meteors burn as they go through the mesosphere layer. However, not all are completely burned some survives and still enter the Earth's surface. These are then called meteorites.
