Describe how the movement of water landforms form
Answer:
The moving of water causes erosion, deposition and much more!
Explanation:
Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.
A ______ is a type of turbine used to capture the energy of moving air. A. geotherm B. windmill C. solar panel D. dam
Answer:
b windmill
Explanation:
A windmill is a type of turbine used to capture the energy of moving air.
Windmills have been used for centuries to power grain mills, water pumps, and other mechanical devices. In modern times, wind turbines are often used to generate electricity on a large scale.
Wind turbines typically consist of a rotor with two or three blades that spin around a horizontal or vertical axis. As the wind blows, it pushes the blades, causing them to rotate and give energy. The rotating blades turn a shaft, which is connected to a generator that produces electricity.
Wind turbines can range in size from small turbines used to power individual homes or businesses to large utility-scale turbines used to generate energy for the grid.

sam enjoys looking at the stars through his telescope he learns that start were originally clouds made of dust and gasses which statement best describes how these clouse eventually become stars
A. The clouds eventually collapse the force of gravity
B. The clouds increase in temperature until they eventually form a solid
C. The clouds contain particles that are magnetically attracted to each other
D. The clouds begin to cool and fort from masses of ice that eventually fuse together
Answer: A
Explanation:
The statement which best describes how the clouds eventually become stars is that— “The clouds eventually collapse under the force of gravity”. Hence, the correct option is A.
What are stars?Star are huge celestial bodies that are formed by the vast clouds that exist in interstellar space. These clouds are mainly composed of hydrogen and helium gas as well as small amounts of heavier elements such as carbon, nitrogen, and oxygen.
Overtime, the clouds begin to collapse under their own gravity and as they do, they become denser and more compact. As the cloud collapses, it begins to spin and then flattens into a disc-like shape. This disc becomes the birthplace of new stars.
The process of star formation is not simple and straight forward. Hence, the first step of formation of stars is the cloud collapses under its own force of gravity. Therefore, option A correct.

Which two events take place during human sexual reproduction?
A. Fragmentation
B. Spore formation
C. Fertilization
D. Gamete formation
Answer and Explanation:
C...
Gamete formation and fertilization takes place during human reproduction. Therefore, option (C) and (D) are correct.
What is sexual reproduction in humans?Human fertilisation produces a human child via human reproduction, which is reproduction. It usually entails activity between a sexually mature male and female person.
Copulation, or sexual intercourse, involves the insertion of the erect into the vagina and the ejection of spermatozoa from the seminal fluid (semen) into the female genital tract. The ovum in the outer portion of the fallopian tube is subsequently fertilised by spermatozoa as they travel from the vagina via the uterus to the tube.

5. How does low biodiversity impact the stability of a tundra ecosystem?
4. Who else benefits from polar bear hunting?
3. Describe a polar bears niche.
1. How do tundra ecosystems in biodiversity compare in biodiversity to other types of ecosystems?
Answer: 5. Biologically numerous groups also are much more likely to include species that confer resilience to that ecosystem due to the fact as a network accumulates species, there may be a better risk of anybody of them having developments that permit them to conform to a converting environment.
3. The polar bear's ecological niche is that of a specialized predator of seals. When there are numerous seals around, adult polar bears will usually devour the blubber (fat) and pores and skin of the seals, which gives an awesome supply of energy. Younger bears will devour beef because the protein allows them to grow.

1. How do tundra ecosystems in biodiversity compare in biodiversity to other types of ecosystems?
Answer: Ecosystems in the arctic tundra are an example of those where there are fewer species overall than in other kinds of ecosystems.
2. What is a niche?
Answer: a role that a species plays in the ecosystem
3. Describe a polar bear's niche.
Answer: Some animals gain from polar bears' hunting of seals. A polar bear will leave behind significant portions of a seal after eating all of it. In tundra environments, these leftovers are a source of food for Arctic foxes, gulls, and other birds, particularly during the chilly winter months when there is nothing to eat. Healthy polar bear populations can have a good effect on other species' numbers, such as those of birds or Arctic foxes. Numerous other species are harmed when polar bear populations drop.
4. Who else benefits from polar bear hunting?
Answer: Arctic foxes, gulls, and other birds
5. How does low biodiversity impact the stability of a tundra ecosystem?
Answer: The species that provide resilience to an ecosystem are therefore far more likely to be found in biologically diverse groups because as a network accumulates species, there may be a greater chance that any one of them will have evolved to adapt to a changing environment.

What are the advantages and disadvantages of the serial dilution-agar plate procedure?
Answer:
Advantages
- Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies.
- In biochemistry, serial dilution is used to obtain the desired concentration of reagents and chemicals from a higher concentration.
- In pharmaceutical laboratories, serial dilution is performed to receive the necessary concentration of chemicals and compounds as this method is more effective than individual dilutions.
- In homeopathy, homeopathic dilutions are used where a substance is diluted in distilled water or alcohol. It is believed than dilution increases the potency of the diluted substance by activating its vital energy.
Disadvantages
- An error might occur during the propagation of the sample, and the transfer inaccuracies lead to less accurate and less precise transfer. This results in the highest dilution to have the most inaccuracies and the least accuracy.
- Because serial dilution is performed in a stepwise manner, it requires a more extended period of time which limits the efficiency of the method.
- Serial dilution only allows the reduction of bacteria/cells but not the separation of bacteria/cells like in other techniques like flow cytometry.
- This technique also requires highly trained microbiologists and experts in aseptic techniques.

(iv) Measles. Mumps, Diphtheria Polio odd one
Answer: The odd one one is diphtheria
Explanation:
There are very minute living organisms that are able to cause different diseases to human which are found in our environment. These are known are microorganisms. They include:
--> viruses
--> bacteria
--> fungi
These microorganisms are able to establish an INFECTION in its human host when it's able fight and overcome the body defence mechanism of the host.
Diphtheria is the odd one because it's an infection which is caused by BACTERIA organism while other options while includes measles, mumps and polio are caused by VIRUS microorganisms.
BACTERIA are the larger microorganisms with a very simple cell structure where the nucleus is not enclosed within a membrane. While VIRUS are the simplest and smallest microorganisms which do not have a cell structure.
Diphtheria is an infection caused by the bacteria microorganism known as the Corynebacterium diphtheriae. These bacteria are able to produce toxins which is its virulent factor that are poisonous to its host.
Measles is an infection caused by paramyxovirus.
Mumps is an infection caused by mumps virus
Polio is an infection caused by picornavirus.
Therefore, Diphtheria infection is the odd one out.
