Which of the following statements is true?
Fusion reactions split hydrogen nuclei apart.
Fission reactions release more energy than fusion reactions.
Nuclear power plants change electricity into nuclear energy.
U-235 is an isotope of uranium.

Answers

Answer 1

Answer:

Fission occurs when a neutron slams into a larger atom, forcing it to excite and spilt into two smaller atoms—also known as fission products. Additional neutrons are also released that can initiate a chain reaction.

When each atom splits, a tremendous amount of energy is released.

Uranium and plutonium are most commonly used for fission reactions in nuclear power reactors because they are easy to initiate and control.

The energy released by fission in these reactors heats water into steam. The steam is used to spin a turbine to produce carbon-free electricity.

Please mark brainliest.

Respiration is the process of inhaling oxygen and exhaling carbon dioxide. Covering a glass prevents the oxygen to enter and can use to test anaerobic respiration. Thus, options 1. a and 2. b are correct.

What is anaerobic respiration?

Anaerobic respiration is a process that uses electron acceptors to produce energy by breaking glucose or other sugar molecules. Unlike aerobic respiration, it lacks the use of oxygen for metabolic reactions.

This occurs in the absence of oxygen and occurs in the cytoplasm with the help of oxidizing substances like nitrate, fumarate, sulfate, etc. to produce less ATP compared to aerobic reactions of respiration.

Therefore, covering a glass prevents the entry of oxygen and can be used to observe the anaerobic respiration by some microbes.

A red frog and a blue frog mate and have offspring. If the gene is Codominant, what will be the color of their offspring?

Answers

Answer:

The correct answer is - blue and red both.

Explanation:

Codominance is the type of inheritance pattern in which alleles interact differently with one other. In this type of inheritance, neither allele is dominant or recessive and both traits are visible in the progeny if both alleles are present together in heterozygous conditions.

Here, in this case, Red frog and the blue frog are in codominance so the cross of these frogs leads to both colors that will be express in offspring together.

A table with four organisms and their primary role in an ecosystem is shown.
Common Name
Role in Ecosystem
Kingfisher
Carnivore
Black fly larvae
Herbivore
Trout
Carnivore
Algae
Producer
Based on the table, which trophic pyramid is correct?

Answers

Answer:Each and every one of us have several roles. Organisms in a community play other roles too. An organism's role within an ecosystem depends on how it earn its nutrients. Organisms collect their nutrients in very different actions, so they have different roles in an ecosystem.

Explanation:  

The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.

For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.

Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

The producer, the algae, is found at the base of the pyramid, and the black fly larva (an herbivore) is found above it. On the third trophic level, there are carnivores such as the trout, and the kingfisher is on the fourth level.

What is the ecological pyramid?

The ecological pyramid is divided into several types, including the pyramid of numbers, the pyramid of energy, and the pyramid of biomass, and the characteristics of the pyramid vary by ecosystem. The pyramid consists of producers at the basal level, which is the algae, and they produce most of the energy in the ecosystem.

The energy and food are then transferred to the second trophic level, the herbivore level of black fly larvae. The third level is the carnivore level (primary carnivore), where the trout eats the herbivore (black fly larva), and the fourth level is the kingfisher, where it eats the primary carnivore, which is the trout, and this results in the pyramid starting with a broad base of producers and eventually narrowing towards the apex.

Hence, the pyramid begins with a producer (algea), then the herbivore, then the trout, and finally the kingfisher.

explain natural selection and how it was demonstrated in this lab(website)

Answers

Hello. It is not possible to access the website you are referring to, but I will try to help you in the best possible way.

Natural selection is the term created by Chales Darwin to compose a theory of biological evolution. According to this term, living beings that have characteristics favorable to their survival, in relation to the environment in which they live, are more likely to survive and pass these characteristics on to their descendants, while those that do not have these characteristics are more likely to die. .

An example of this can be seen in a population of lizards that live in environments with a lot of grass. According to natural selection, green colored lizards would have better advantages of surviving because they would be camouflaged in the grass and would not be seen by predators, unlike red lizards, which would be easily identified and captured by predators. therefore, the population of red lizards would decrease until it ceased to exist, while the population and green lizards would survive and generate other green lizards.

Why are there many, many more craters on the "outer back" side of the moon than there are on the "inner facing" side of the moon?

Answers

Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.

Explanation:

The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.

Some cells can die as a result of external agents suck as poison or trauma. However, most cells die through a process known as apoptosis, or programmed cell death. What is a likely consequence of a mutation that prevents apoptosis

Answers

Answer: A tumor

Explanation:

A mutation that prevents apoptosis can disrupt the normal cellular mechanisms that prevent tumor formation, and lead to the uncontrolled growth of cells that could ultimately cause cancer.

What is apoptosis?

A mutation that prevents apoptosis, or programmed cell death, can have several consequences. One of the most significant consequences is the accumulation of damaged or abnormal cells, which can lead to the development of tumors and cancer. Apoptosis is a natural process that eliminates cells that are no longer needed or that are damaged beyond repair. This process is essential for maintaining tissue homeostasis and preventing the growth of abnormal cells.

When cells are prevented from undergoing apoptosis, they may continue to divide and proliferate uncontrollably, leading to the formation of a mass of cells known as a tumor. This is because cells that have undergone DNA damage or that have other abnormalities are normally eliminated through apoptosis to prevent the accumulation of cells that could become cancerous.
