Which type of plant would NOT
live on land?
A. alga
B. fern
C. moss
D. roses
Answer:
A. AIga
Explanation:
Alga can live in freshwater lakes or in salt water oceans. Most green alga occur in fresh water, usually attached to rocks and wood.
The ferns are most commonly plants of shaded damp forests of both temperate and tropical zones. Some fern species grow equally well on soil and upon rocks others are confined strictly to rocky habitats.
Mosses are distributed throughout the world except in salt water and are commonly found in moist shady locations. They are best known for those species that carpet woodland and forest floors. Hence, mosses break down exposed substrata, releasing nutrients for the use of more complex plants that succeed them.
Roses typically grow in warm climates and flower in the summer months. However, some roses can grow in the hot tropical climate found in Florida, while others can grow in hardiness zones as low as 2, which have winter temperatures that drop as low as -50 degrees Fahrenheit.
Hence, A. Alga is the correct Answer.

An inventor claims to have invented an artificial kidney for patients that need a kidney
transplant. Which of the following would be a reason that the scientific community might
reject this claim?
A. Previous investigations were unable to obtain the same results.
B. The inventor failed to present observations with data.
C. Investigations were performed in an unknown laboratory.
D. The device failed to follow law of conservation of mass
All of the given options could potentially be reasons why the scientific community might reject the inventor's claim, but the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.
What is an artificial kidney?In the case of an artificial kidney, the device is supposed to filter out waste products from the blood, which is then supposed to be removed from the system in a measurable form, such as through urine or dialysis fluid. If the device fails to remove the waste products from the blood, or if it makes them disappear without a measurable output, it would suggest that the device is not functioning as claimed and may not be effective in treating patients who need a kidney transplant. Therefore, the scientific community would likely reject the inventor's claim until there is evidence that the device follows the fundamental principles of science, such as the law of conservation of mass
Hence, the option that specifically relates to the principles of science is option D: the device failed to follow the law of conservation of mass.

The Diagram shows structures that form the surface of the trachea.
Which level of organisation is the structure labelled S ?
A. Cell
B. Organ
C. Organ system
D. Tissue
Structure S is a simple columnar epithelium, which is a type of tissue.
The diagram shows the structures that form the surface of the trachea. The trachea is a tube that carries air from the lungs. The surface of the trachea is lined with a layer of tissue called the epithelium. The epithelium is made up of cells that line the inside of the trachea.
The structure labelled S is a type of epithelium called a simple columnar epithelium. Simple columnar epithelia are made up of cells that are arranged in a single layer. The cells in a simple columnar epithelium are tall and column-shaped.
The simple columnar epithelium in the trachea helps to protect the trachea from infection. The cells in the epithelium produce a mucus that traps dust and other particles. The mucus is then carried away by the cilia, which are tiny hairs that line the trachea.
The other levels of organization in the diagram are organ, organ system, and cell. The trachea is an organ, which is a collection of tissues that work together to perform a specific function. The respiratory system is an organ system, which is a group of organs that work together to perform a common function. Cells are the basic units of life, and they are the building blocks of tissues, organs, and organ systems.

What is the relaxed form of dna in a cells nucleus?
Answer:
The relaxed form of DNA that can be found in the nucleus is referred to as chromatin. This form of DNA is observed when the cell is not dividing.
Explanation:
hope this helps
The relaxed form of DNA in a cell's nucleus is called chromatin.
CHROMATIN:Chromatin is a complex of DNA and histone proteins within the cell's nucleus. The DNA is too long to fit into the cell's nucleus, hence, is coiled around proteins called histones. This complex forms the structure called chromatin, which then condenses during the prophase stage of cell division to form a more compact structure called chromosome.Therefore, it can be said that the relaxed or uncondensed form of DNA in the nucleus of a cell is called chromatin.

Are gender traits completely a result of societal expectations?
No, Gender traits are not as a result of societal expectations. They are as a
result of biophysical processes in the body.
Both genders have their unique chromosomes composition in which
Males have XY.Females have XX.During reproduction, the male sex cell passes either the X or Y chromosome
to the offspring while the female pass only the X chromosomes.
This depicts that the male sex cells which is the sperm is the main

drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.
Neurons are cells in chauge of synapsis. a)cell body / b)myelin sheath / c)synaptic terminal / d)axon hillock / e)nucleus / f)location of voltage-gated channels / g)location of ligans-gated channels / h)axon / i)dendrite
-------------------------------
Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons. These connections are known as synapsis.
During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.
Besides, there is an increase in sodium permeability.
Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.
The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.
The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.
