Answer:
Explanation:
Phylum Gnetophyta ✌
Distinguishing characteristics of the phylum Gnetophyta include the presence of both tracheids and vessels in their xylem tissue, a unique fertilization feature in which a tube grows from the eggs to unite with pollen tubes, and being the only division of gymnosperms that undergo double fertilization. Gnetophyta plants include trees, shrubs, or stumpy, turnip-like growth forms with simple leaves.
The phylum Gnetophyta consists of three genera of woody plants called Gnetum, Welwitschia and Ephedra. Although the three genera are all gnetophytes, they are highly specialized to their respective environments, which makes it difficult to identify similar characteristics.
Gnetum species are mostly woody climbers in tropical forests, although the best-known member of the group is a tree. Welwitschia includes one species, Welwitschia mirabilis. It only grows in the deserts of Namibia and Angola, and has two large strap-like leaves that grow continuously from the base throughout the plant's life. Ephedra plants are known as joint-firs because they have long slender branches with tiny scale-like leaves at each node. Ephedra is traditionally used as a stimulant. The plant and its derivatives are classified as controlled substances in many jurisdictions because of the high risk of addiction, harmful side effects and fatal overdoses.

The reason why this is an investigation and not an experiment is F. Other scientists are unable to replicate her results because there is only the one fossil.
When would this be an experiment ?Rather than carrying out a systematic, regulated trial, the scientist is simply taking note of what she sees and learns concerning the relic of a dinosaur found within her local park.
Evidently, this investigation deviates from standard experimentation, as the data collected in her notepad are based solely on her observations and opinions about the fossil rather than an outcome resulting from a constrained experiment.

What is the net force?
Answers
Fnet=5N. When a force is applied to the body, not only is the applied force ,there are many other forces like Fg, Ff and the normal force that balances the other force.
How to solve ?Therefore, the net force formula is ,
F net = Fa + Fg + Ff + FN.
Where,
Fa is applied force,
Fg is the gravitational force,
Ff is the frictional force,
FN is a normal force.
Force FN= 3N
Force Fg = 3 N
Force Ff = 5N
The net force formula is given by
FNet = FN-Fg + Ff
FNet = 3-3+5
FNet = 5N
Therefore, the net force is 5N.
With kinetic friction, how do you determine net force?Ff=kFN F f = k F N, where k is the coefficient of kinetic friction and FN is the object's normal force, is the formula for kinetic friction.
With net force and direction, how do you calculate force?The net force is what remains when two forces acting on an item in opposite directions don't exactly cancel out (the difference in the forces). The net force is the sum of the forces acting on an object when two or more forces are acting on it in the same direction.

there was a difference in the intensities in the vanilla or the evergreen. Based on the information presented in this scenario, which
of the following is true?
Vanessa has a more sensitive difference threshold than Carlton.
Carlton has an impaired absolute threshold.
Vanessa has a better absolute threshold than Carlton.
Carlton has the superior performance with respect to the difference threshold.
Vanessa has an impaired absolute threshold.
Answers
Vanessa has a better absolute threshold and more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
Carlton and Vanessa were lab partners for a biology class and were asked to run a smell test experiment on each other.
Vanessa was excellent at noticing the difference between various intensities of vanilla and evergreen.
Carlton, on the other hand, couldn't distinguish the difference in the intensities of both vanilla and evergreen, though he could tell the smells of both.
Hence, based on the information provided in the scenario, it can be inferred that Vanessa has a more sensitive difference threshold than Carlton, and Carlton has an impaired absolute threshold.
The two significant aspects that are involved in the scenario are absolute threshold and difference threshold.
The absolute threshold is the smallest quantity of a stimulus that an individual can detect, whereas the difference threshold is the minimum difference in stimuli that an individual can detect.
Carlton could recognize the stimuli's smell but not the difference in the intensity of vanilla and evergreen.
This shows that Carlton has an impaired absolute threshold.
He could not detect the smallest quantity of a stimulus to differentiate between the smells.
Vanessa was quite good at noticing the difference in the intensities of vanilla and evergreen.
This means that Vanessa has a more sensitive difference threshold than Carlton. She could detect the minimum difference in stimuli required to differentiate between smells.
Vanessa also has a better absolute threshold than Carlton as she could detect the smallest quantity of stimulus required to detect the smells.

Categorize each relationship as mutualism or parasitism
Answers
The question is unclear, is there more to it?
I cannot answer this question without knowing the circumstances, but it is good to remember that mutualism is where both species and/or participants benefit, and parasitism is where one species benefits and the other one is harmed.
Think of mutualism like the word mutual, so when people say " the feeling is mutual" it means that both parties feel and/or express the same feelings. Parasitism should be thought of like a parasite. When one is infected or has contracted a parasite, the parasite will live off of its host body making it ill or even causing death as it drains resources from its host to benefit itself.

How would an air mass that formed over the north pole differ from an air mass that formed over a warm
ocean?
Answers
An air mass that formed over the North Pole would differ from an air mass that formed over a warm ocean in several ways.
Air masses are large bodies of air with similar characteristics that form over a specific region of the Earth's surface and can travel long distances before encountering a different air mass that alters its characteristics. The characteristics of an air mass depend on the region over which it forms.
The air mass that forms over the North Pole would be cold and dry due to the absence of sunlight and the Arctic's high latitudes. Arctic air masses are characterized by a high pressure system that circulates air clockwise. This rotation traps cold air over the region and prevents it from mixing with the surrounding air masses.
The air mass that forms over a warm ocean would be warm and moist. The ocean surface warms the air above it, and the air acquires moisture through evaporation. The warm air then rises, causing low-pressure areas over the ocean and pulling in moisture-laden air from surrounding regions. This moist air mass travels over land, and its temperature decreases, causing it to lose its moisture content and form precipitation.
The moisture content in this air mass would be high, causing it to be humid. Air masses interact with each other and cause changes in weather patterns and climate. They also play a vital role in the Earth's energy balance and regulate temperature and precipitation patterns.

The diagram below represents an event that occurs in the BLOOD
Answers
The blood clotting process is seen in the diagram. It demonstrates how the blood's platelets, fibrin, and other elements combine to produce a clot.
What is platelets?Blood contains tiny, colourless cell fragments called platelets, which are crucial for clotting. Thrombocytes are another name for platelets. In the bone marrow, they are made and then released into the blood. To stop bleeding, the body uses platelets to assist clots form. In blood vessel damage, they group together and create plugs to stop the bleeding. Additionally, platelets exude substances that support clotting and aid in blood vessel healing. A platelet's lifespan is roughly 10 days until it is destroyed by the body. Between 150,000 to 450,000 platelets per microliter of blood constitute a normal platelet count. Thrombocytopenia is a low platelet count.
In order to stop additional bleeding, platelets and fibrin combine to create a plug. This structure strengthens the clot. This procedure is crucial for limiting excessive blood loss and maintaining the circulatory system's integrity.

In Metaphase, the chromosomes are all aligned in the center of the cell.
O True
O False
Answers
True. During metaphase, the chromosomes line up in the center of the cell in a process called the metaphase plate.
What do you mean by metaphase?
Metaphase is one of the stages of mitosis, the process of cell division. During metaphase, the chromosomes line up in the middle of the cell and are attached to the spindle fibers. The centrosomes, located on opposite sides of the cell, move apart and form the spindle fibers. These fibers attach to the chromosomes and pull them to the middle.
The positioning is important for the cell to accurately separate the chromosomes during the next stage of cell division, anaphase.

chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.
Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.
Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.
Ribosome: The part of the cell that is responsible for creating proteins.
The cell wall is an extra protective layer around the plasma membrane, and allows for plant protection from bacteria, water etc. The Golgi apparatus is an organelle within plant cells that modifies, packages, and transports proteins and lipids throughout the cell. Chloroplasts are organelles within plant cells that are responsible for photosynthesis. They contain thylakoids and the stroma. The cell membrane (aka plasma membrane) is made up mainly of phospholipids. It is selectively permeable, meaning it only allows certain substances to pass, usually small, non-polar particles. Ribosomes are the sites of protein synthesis, or where proteins are built. Hope that helps!
