Answer:
All statements are true and explain the function of most organelles present in the cell.
Explanation:
I remember the following:
-The nucleus directs cell activity: the nucleus is where the genetic information is found and by means of gene expression it controls the cellular functions.
-Ribosomes produce proteins for the cell: Ribosomes make messenger RNA proteins (mRNA) by connecting amino acids together
-These proteins are then moved through the cell by the endoplasmic reticulum: it is a network of membranes within the cell through which proteins and other molecules move
-The Golgi apparatus packages and distributes proteins from the endoplasmic reticulum: It transforms and exports protein to the rest of the body. Proteins, in their passage through the Golgi apparatus, carry out a modification process.
-Vacuoles store water, waste products, food, etc: vacuoles store substances, in plants they occupy a large percentage of the cytoplasm and change their size during ormoregulation.
-Lysosomes break down waste material and debris: They contains hydrolytic enzymes that allow intracellular digestion of macromolecules
-Mitochondria break down sugar molecules to supply energy. Similarly, chloroplasts capture the energy from sunlight and convert it into chemical energy: Chloroplasts and mitochondria through the processes of cellular respiration and photosynthesis produce energy necessary for the vital functions of the cell.
-The cell membrane protects the cell and controls what enters and leaves it. The cell wall supports the cell membrane, maintains the cell’s shape, and protects the cell. The cytoplasm supports and protects organelles in the cell: The membrane is the support of the cell and through it there is exchange with the external environment. The cytoplasm is the one that supports the rest of cellular organelles
The up welling of volcanic magma. This also make the flat rock be uplifted in to the plateau
Answer:
Spring Tides.
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.
This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
The various types of ocean tides based on the position of the Earth, Moon and the Sun are;
I. Neap tides.
II. Spring tides.
III. Low tide.
IV. High tide.
V. Brown tide.
VI. Rip tide.
VII. Red tide.
Answer:
The continents were once connected, and marsupials were able to migrate over the land.
Explanation:
There are a lot of evidences present which indicates that the continent were once connected and present as a super continent but with the passage of time, this super continent splits into two parts and go far from each other. Marsupials also present on two different continents such as America and Australia. These two continents first attached to one another and these Marsupials spreads on these lands. With the passage of time, they splits and go far from one another.
