A student observes a cell under a microscope. She sees a cell wall and a nucleus. What type of cell is she observing?
O eukaryotic animal cell
O eukaryotic plant cell
O prokaryotic cell
O bacterial cell
Answer:
eukaryotic plant cell
hope this helps
Only eukaryotic plant cells have a cell wall and a nucleus. Option 2 is correct.
Eukaryotic cells are cells that have a nucleus and other membrane-bound organelles. Prokaryotic cells do not have a nucleus or other membrane-bound organelles.
Plant cells are eukaryotic cells that have a cell wall. The cell wall is a rigid structure that surrounds the cell membrane. It provides support and protection for the cell. Animal cells do not have a cell wall.
The nucleus is the control center of the cell. It contains the DNA, which is the genetic material of the cell. The nucleus also contains proteins that control the activities of the cell.
So, if a student observes a cell under a microscope and sees a cell wall and a nucleus, she is observing a eukaryotic plant cell.

Explanation:
One person pulls on a rope with a force of 400 N to the right. Another
person pulls on the opposite end with a force of 600 N to the left. What is
the net force?
Two forces are applied on the rope of the magnitude 400N to the right and 600N to the left, as a result of these forces the net force on the object will be 200N. Thus, the correct option is A.
What is Net force?Net force is the resultant force of the total force which is being applied on an object. It is the sum total of the effect of all the forces on an object. Forces which are applied in opposite directions cancel out each other.
If the net force applied on an object is not zero, then it can be said that the object is not in equilibrium, and thus Newton's Second Law can be used to determine the motion of the object.
Here, two forces of different magnitudes and in opposite directions are applied on the rope to pull the rope. The forces are 400N to the right and 600N to the left.
As a result of these forces, the net force applied on the rope can be calculated by:
Net force = Difference between the forces applied in opposite directions or the sum of the forces which are applied in same direction
Net force = 600N (force applied to the left) - 400N (force applied to the right)
Net force = 200 N and the direction will be left as the magnitude is more in left direction than right
Therefore, the correct option is A.

Explanation:
what do you think will happen when i put a leaf discs saturated with a sodium bicarbonate solution and put it under a lamp ? will it sink or float and why ? can someone help me rq will give 30 points
Answer:
the leaf disk should float because bicarbonate is the source of its oxygen for photosynthesis and it releases oxygen into the interior of the disk causing it to float.
Explanation:
The thing which would happen if leaf discs are saturated with a sodium bicarbonate solution and put under a lamp is:
The leaf disk would floatAccording to the given question, we can see that there is an experiment which is taking place as a leaf disc is placed in a solution of sodium bicarbonate under a lamp.
As a result of this, we can see that the source of oxygen for the leaf disk is the bicarbonate and when the chlorophyll in the plant reaches out to the lamp for photosynthesis, it would make the leaf disk to float.

Answer:
DNA
Explanation:
The DNA of a human being is very unique as each human has a different sequence of it. This allows for it to be used for very precise identification of humans such that it has been used to solve crimes.
DNA is also present in every cell in the human body which is why it is useful in anthropology as well. Anthropologists can simply extract cells from a bone and through the DNA extracted, find out more about a dead person.
Therefore, DNA is the answer.

Answer:
underground stem -- for storage of food ex. potato , ginger.
spines for protection ex. citrus , bougainvillea
Explanation:
Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it.

Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease

Entre los siguientes métodos de separación de mezclas, Jorge debe seleccionar el adecuado para separar sal de una mezcla de sal y agua, en la que la sal se encuentra completamente disuelta.
50%
Teniendo en cuenta la composición de la mezcla, ¿cuál de los anteriores métodos debe usar Jorge para separar la sal?
Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
Evaporación, porque este método únicamente se usa para separar líquidos.
Filtración, porque la sal y el agua se mezclan muy bien.
Filtración, porque la sal es blanca y el agua transparente.
Teniendo en cuenta las definición de evaporación, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
El método de separación utilizado para el agua y la sal es: la evaporación.
La evaporación consiste en pasar el soluto disuelto en un liquido a estado gaseoso y ocurre al aumentar su temperatura de forma natural o artificial,. Dependiendo de que se desea evaporar se utiliza el material correspondiente. La técnica mas común es por contacto y puede acelerarse si utilizamos un material conductor dentro del liquido.
En otras palabras, se conoce que la evaporación es el proceso por el cual las distintas moléculas en estado líquido, como lo es en agua, pasan a un estado gaseoso de manera espontánea, siendo este el principal efecto de la evaporación.
Como se mencionó el método de separación utilizado para el agua y la sal es la evaporación. Durante este proceso, al aplicar calor, el agua se convierte en vapor y se libera al aire. La sal, como tiene otro punto de ebullición, no se evapora.
Entonces, la respuesta correcta es la primer opción: para separar la sal, Jorge debe usar la Evaporación, porque con este método se evapora el agua y queda únicamente la sal.
