Answer:
The correct answer is - flagellated sperm.
Explanation:
In ancestral trait that is flagellated sperm in ferns that were limited to moist habitat has sperms that must swim to the eggs. This is why ferns often require splashing water for the movement of sperm to points near female gametangia during reproduction.
Fern now adapted the vascular system to get life on the life and they are not limited to the water bodies, however, flagellated sperm is the ancestral reproductive trait.

Label the following topographic map. Click on a label below the map to select it, and then click on the appropriate box on the map to place the label. (Increments for contour lines is 50 feet).
Choices:
River Flow East
Depression
2650 feet
Sleep Area
Based on the information, it can be inferred that the concepts are organized from left to right as follows: Depression, Sleep area, River Flow East, and 2650 feet.
How to identify the correct space for each concept?To locate each concept in the correct space we must know how to read a topographic map. In this case, the depression would be the first concept because in the shaded area the contour lines are shown very close, this is generally related to a depression area in which the slope is very pronounced.
On the other hand, the sleeping area is at the top of the mountain at the bottom of the image because a flat region is shown on the top of the mountain.
Additionally, the blue line through the topographic map represents a river so this could be labeled River Flow East. Finally, the contour line that is at 2650 feet high would be the last space considering that each line represents an increase (or decrease) of 50 feet.

What word is used to describe plant cells placed in a hypotonic solution?
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

Explanation:
Oxygen has an atomic number of 8. The n=1 energy level has two electrons, and the n = 2 energy level has six electrons. Oxygen's valence is _______.
● +2
● -2
● +1
● -1
Answer:
Oxygen's valence is +2
the answer is +2
I hope this helps
Answer:
● -2
Explanation:
Oxygen needs to gain 2 more electrons to have 8 electrons in outer most shell (octet rule). Gaining electrons makes you negative thus, oxygen gains 2 electrons and has valence of -2.

The invention of the microscope led to the discovery of the cell by Robert Hooke. While looking at cork, Hooke observed the box-shaped structures, which he called "cells" because they reminded him of the cells (rooms) found in monasteries. This discovery led to the development of the cell theory. Credit for developing the cell theory is usually given to two scientists. Theodor Schwann and Matthias Schleiden. The cell theory was then proposed by Theodor Schwann in 1839. There are three parts to this theory: living organisms are made up of cells, cells are the basic structural unit of all organisms, and all cells come from pre-existing cells. Which of these is supported by the tenets of the cell theory? Select ALL that apply. les )) A) Energy flow occurs within cells. B) Mitosis produces identical daughter cells. C) Living organisms can be unicellular or multicellular. D) DNA is copied and passed between cells during cell division. E) Single-celled bacteria grow and then divide in half to make new bacteria.
Living organisms are made up of cells, cells are the structural unit of all organisms, cells come from pre-existing cells Energy flow occurs within cells.
What are the main points of cell theory?The main points of cell theory are:
All living things are made up of cells.Cells are the raw building blocks of life.All cells come from preexisting cells through the cycle of cell division.Energy flow occurs within cells.Thus, cells come from pre-existing cells Energy flow occurs within cells.

Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.

What form is DNA in during mitosis?
A. protein
B. ribosome
C. chromatin
D. chromosomes
Answer:
Chromosomes form is DNA in during mitosis.
Explanation:
In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
During mitosis, DNA is in the form of chromosomes, which is option D, as the chromosomes are condensed and highly coiled structures made up of DNA and associated proteins called histones.
During mitosis, a cell divides into two daughter cells that are genetically identical to the parent cell. Chromosomes are critical to this process because they carry the genetic information necessary for the formation of the new cells, and before mitosis begins, the chromatin (a complex of DNA and proteins) in the nucleus of the cell condenses into visible chromosomes. This condensation process involves the compaction of chromatin into a more compact and organized structure.
