The similar shapes of fast swimming marine predators are an example of:__________
Answer: convergent evolution
Explanation:
The similar shapes of fast swimming marine predators are an example of convergent evolution.
Convergent evolution shows how different species possess identical structures even though they evolve separately. Convergent evolution typically takes place with the organisms that are not really related.
An example of convergent evolution is the similarity that can be noticed in the wings or the flights of bats, birds, insects, etc
You will be researching a virus that infects humans, animals, or plants. If you are into history you may pull a virus that has occurred (like one of the flu pandemics) To share your research you will be creating a digital poster. You may use any type of poster program you like as long as it can be shared! You may also use google slides. I will provide a template for google slides (link will be here) if you need help getting started! To get full credit, your poster must include the following: At least 8 of these 10 items Name of virus Time span (is it currently out there infecting things? Is this from the past?) What it infects How does it spread? What are the symptoms? How dangerous is it? At least one relevant image (with a citation if you did not create the image) A description/caption for the image explaining the relevance How does it reproduce? (lytic or lysogenic) What are its viral relatives? Did it evolve from another known virus? AND A list of references all while using academic grammar and spelling! Post a link to your poster or upload your poster here in the Discussion Board. This discussion board will not be much of a discussion - it will be more of a sharing of work!

Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another. Thus, option 1. C, 2. A , 3. D, 4. B is correct.
What are different phases of matter?Depending on the pressure and temperature circumstances, a given set of matter can change its state or phase, transitioning to different phases as these variables change to favor their existence.
The primary distinction between a substance's phase and state can be summed, For instance, a solid can convert to a liquid when the temperature rises.
A substance's phase describes its uniform chemical and physical qualities, whereas a substance's state describes its shape at a specific temperature and pressure.
Therefore, A phase change from a solid to a liquid represent melting.

an example of how water moves from
the biotic part to the abiotic part of an
ecosystem.
One of the important examples of how water moves from the biotic part to the abiotic part of the ecosystem includes transpiration of water from the surface of the leaves of plant.
What is Transpiration?Transpiration is the loss of water in the form of vapors from the surface of leaves of plant. Transpiration of water takes place from the stomata of plant cells.
Stomata are the specialized cells present on the surface of leaves which are covered by the guard cells that regulates the opening and closing of stomata and hence the movement of water from the leaf surface.
In transpiration, water from plant, a biotic part of ecosystem is lost in the form of vapors to the atmosphere, i.e., an abiotic component of ecosystem. The rate of transpiration is regulated by factors such as sunlight, concentration of ions like sodium and potassium, presence of starch.

Which state of matter does this model represent?
A} solid
B} liquid
C} gas
D} plasma
The state of matter represented by the above image is a liquid (option B).
What is matter?Matter is the basic structural component of the universe. Matter usually has mass and volume.
Matter exists in three states namely;
Solid: the particles of a solid are very attracted to each other. They are close together and vibrate in position but don't move past one another.Liquid: In a liquid, the particles are attracted to each other but not as much as they are in a solid.Gases: In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don't interact with one another but just hit and bounce off of each other when they collide.Based on the particles of the substance in the image above, one can observe that they are closely but not tightly packed, which suits the description of liquid state.
Therefore, the particles of the substance in the model represent a liquid.

Fennec foxes (desert foxes) have ears up to 15 cm long. Thousands of years ago there was huge
variety in the size of the ears. Over time, those with the biggest ears were able to better survive as
they can lose more heat in the hot summer months. What would you expect to happen to the length
of Fennec fox ears if the temperature in the desert increases?
Answer:
You would expect their ears to also increase in size.
Explanation:
As the question says the ones with the biggest ears survived the best, implying if the temperatures rose the length of the ears would as well so that they could give off body heat.
