Answers

The rock in diagram A has three horizons and no force acts on it.

What is a rock?

A rock is a geological term that refers to solid materials, made up of crystals or grains of one or more minerals. Rock is the main material in the Earth's crust.

Four diagrams of the Earth's crust are shown in the image. All four have three horizons and different forces influence them except A. These forces are caused by the movements of the Earth's lithosphere and are represented by arrows in the direction of movement.

In the case of diagram A, having no arrow means that no force acts on it. Additionally, you can see the three horizons or layers that make up this sample of land.

In the triangles, HG = MP and GK = PN. Triangles H G K and M P N are shown. Side H K has a length of 15 millimeters. Side M N has a length of 11 millimeters. Sides H G and M P are congruent. Sides G K and P N are congruent.

Answers

Since HG = MP and GK = PN, triangles H G K and M P N are congruent by the Side-Side-Side (SSS) congruence criterion.

Therefore, the corresponding angles and sides of the two triangles are equal. In particular, we have:

Angle H is congruent to angle M (corresponding angles).

Angle G is congruent to angle N (corresponding angles).

Side HG is congruent to side MP (given).

Side GK is congruent to side PN (given).

Side HK is congruent to side MN (given).

Based on this, we can conclude that the following statements are true:

Angle H is congruent to angle M.

Angle G is congruent to angle N.

Side HG is congruent to side MP.

Side GK is congruent to side PN.

Side HK is not congruent to side GN, as they are not corresponding sides.

Scarification is a process that scratches up the surfaces of seeds that pass through the guts of birds. A student wanted to see if scarified seeds grew better than those that were not scarified. He simulated scarification by rubbing 20 cherry seeds with sandpaper. Another set of 20 cherry seeds were left alone. The student planted each of the seeds into separate pots and gave them the same amount of water daily. The pots were placed in a location with a constant temperature of approximately 25 degrees C. The number of seeds that germinated each group was recorded daily for three weeks. Which is the control group?
Which is the experimental group?
What is the independent variable?
What is the dependent variable?

Answers

The control group is the set of non-scarified seeds. The experimental group is the set of scarified seeds. The independent variable is scarification process. The dependent variable. is the number of seeds that germinated in each group.

Controlled variables are the amount of water supplied daily, the constant temperature of the growing environment, the type of cherry seeds used and the size of the planting pots.

Quantitative data are the daily count of the number of seeds that germinated in each group over three weeks.

The study does not have qualitative data.

Differences between dependent and independent variablesThe independent variable needs no stimulus to generate results.The dependent variable needs to be stimulated by the independent variable to generate results.

Hope i helped, good luck on the test :)

The statement which is true about Fungi are as follows:

The reproductive organs of a fungus are the Mycelium, an underground network of threads.

Thus, the correct option is D.

What are Fungi?

Fungi may be defined as a group of eukaryotic organisms that lack chlorophyll, leaves, true stems, and roots, reproduce by spores and live as saprotrophs or parasites.

Due to the absence of chloroplasts, fungi are not similar to plants. Fungi are eukaryotic heterotrophs organisms.

Spores are the fundamental reproductive units of fungi. The reproductive organs of a fungus are the Mycelium which is hidden until it is able to develop one or more fruiting bodies.

Therefore, the correct option for this question is D.

An invasive species, the spiny water flea, was recently found in a New York lake. These water fleas eat zooplankton, a food also consumed by native fishes. The fleas spread from lake to lake by attaching to fishing lines, anchor ropes, and boats. Which statement best describes the effect of the water flea on the lake?

Answers

The introduction of the spiny water flea into the lake is likely to have a negative effect on the balance of the native ecosystem, as the water fleas will compete with native fish for resources such as zooplankton, and may disrupt the existing food chain.

What is a Water flea?

A water flea is an aquatic crustacean. Normally, it is a member of the order Cladocera, meaning it has a small body, two antennae, and a single shell (a carapace) over its back. Water fleas move by using the hair-like setae which are located on their legs. They are an important part of aquatic ecosystems as they are used as food by other aquatic organisms. They also help to clean up organic matter in water bodies, thus improving water quality.

What is a zooplankton?

A zooplankton is a microscopic or tiny aquatic animal, usually found in oceans or freshwater bodies. They are usually very small in size and typically feed on phytoplankton. Zooplankton are key components of aquatic food webs and are a vital part of the aquatic environment. They are also important for carbon cycling, filtering pollutant particles from the water, providing food for fish and other aquatic organisms, and providing a food source for larger predators.

Vestigial structures are structures that have no obvious purpose and appear to be leftover components from a previous progenitor. The human appendix, a snake's pelvic bone, and the wings of flightless birds are all examples of vestigial features.

2. What is analogous structure?

Analogous structures are characteristics of various species that are comparable in function but not necessarily in form, do not come from a shared ancestral feature (in contrast to homologous structures), and evolved in response to a similar environmental challenge.

3. What is homologous structure?

Homologous structures are physical traits that are comparable in species with a common ancestry but perform radically distinct purposes. The limbs of humans, cats, whales, and bats are examples of homologous structures.

Someone makes a loud noise and it scares you use complete sentences to put the following vocabulary terms in order to describe how the body processes the sound and reacts central nervous system, sensory organs, and sensory receptors

Answers

Answer:

When someone makes a loud noise and it scares you, your body goes through a series of processes to respond to the sound. I'll break it down using the terms you mentioned.

Explanation:

Sensory organs: These are specialized parts of your body that detect stimuli from the environment. In the case of hearing a loud noise, your ears are the sensory organs responsible for detecting sound waves.

Sensory receptors: These are specialized cells within your sensory organs that convert the stimuli, in this case, sound waves, into electrical signals that can be understood by your body. In your ears, tiny hair cells act as sensory receptors, converting the sound waves into electrical signals.

Central nervous system: This refers to your brain and spinal cord, which are the main components of your central nervous system. Once the sensory receptors in your ears convert the sound waves into electrical signals, these signals travel through nerves to reach your central nervous system.

So, in the situation where someone makes a loud noise, the sound waves are detected by the sensory organs (your ears), which then send the information to the sensory receptors (hair cells). The sensory receptors convert the sound waves into electrical signals, which are then transmitted through nerves to your central nervous system (brain and spinal cord).

Once the electrical signals reach your central nervous system, your brain processes the information and determines that the loud noise is something to be concerned about. It may trigger a response, such as a startled reaction or the feeling of fear. These responses are coordinated by your central nervous system, which sends signals to various parts of your body to react accordingly.

So, the order of the processes involved in how the body processes the sound and reacts to a loud noise is: sensory organs (ears) -> sensory receptors (hair cells) -> central nervous system (brain and spinal cord).
