Why did the dinosaur extinction have a happy ending for us? PLEAASEE!!

Answer:

about 73%

Explanation:

Answer:

About 75% of the brain is made of water.

Answer: Plants, unlike animals, can make their own food. They do this using a process called photosynthesis . During photosynthesis, plants produce glucose from simple inorganic molecules - carbon dioxide and water - using light energy.

Answer: A

Explanation:

An oceanic basin is the land surface under an ocean that includes the various topography below the water. This includes the continental shelf, abyssal plain, mid-ocean ridge and other formations that may exist on the seafloor.

In eukaryotes, transcription takes place in the nucleus first, and then translation takes place in the cytoplasm at free and membrane-bound ribosomes.

In prokaryotes, transcription and translation both occur in the cytoplasm and simultaneously.

Answer:

It's C. Plants produce oxygen and nutrients via a process known as photosynthesis using water and carbon dioxide

Answer:

bacteria

Explanation:

'Bt' crops are genetically modified crops that contains a certain gene of a bacteria called Bacillus thuringiensis. The name of this GM or transgenic crop was coined from the bacteria used.

The gene coding for the toxic traits of the bacteria are added into Bt crops e.g cotton, hence, the crops become resistant to pest attack. Therefore, according to this question, BT crops are developed by adding traits from BACTERIA.

Answer:

organ

Explanation:

The highest level of organization for living things is the biosphere; it encompasses all other levels. The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.

The biological level of organisation range from organelle to biosphere. Therefore, option (A) cell  forms the fundamental base.

Cells join to form tissues in larger animals, which are clusters of similar cells performing similar or related jobs. Organs are groups of tissues that work together to fulfill a certain task. Organs can be found in both plants and animals. An organ system is a more advanced level of organization made up of organs with similar functions. 

A population is the aggregate term for all members of a species that are present in a given location. An ecosystem is made up of all the living things that exist in a specific location as well as the abiotic, non-living elements of that environment, such as soil nitrogen or rainwater. The biosphere is a group of organisms that is organized at the highest degree possible.

Thus, option (A) cells forms the fundamental base for all other levels

Explanation:

Because dense minerals are heavier and drop to the stream bottom, lighter minerals are carried along in the current of the stream. Why do you think that mining on land is less costly than mining in the deep ocean is? It is easier to get to land than the ocean and you need special equipment to go under water.

Explanation:

Answer:

Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. Atoms with large differences in electronegativity transfer electrons to form ions. The ions then are attracted to each other.

Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment.

Cell respiration occurs in all eukaryotes

Answer:

Greatly affected.

Explanation:

This closing of nuclear power stations greatly affect the future balance of sources of energy used for electricity production in the UK because the burden of production comes on other sources such as production of electricity from fossil fuels, wind and solar radiation etc. If electricity is produced from fossil fuels so it leads to pollution of the environment whereas if the electricity is produced from wind and solar radiation, it is very costly but good for the environment.

Answer:

Yes.

Explanation:

Yes, a tree is falling over in a forest make a sound because both the tree and ground are hard surfaces which can produces sound by contact physically with each other. For testing this hypothesis, we have to take a tree and cut that tree. when the tree falls on the ground it will definitely produces sounds by contact physically with the ground when falls with a large force.

Answer:

hiii

Explanation:

Answer: Well, deforestation is cutting down trees, and many arboreal animals live in those trees. So if they have no proper shelter, they would have no place for personal activities such as breeding, feeding etc. And without those important activities that they have to do everyday, the population of arboreal animals will keep on decreasing until they go extinct. Though that's not the only problem. The herbivores won't get anything to eat, hence not letting the omnivores or carnivores get their food. As you can see, deforestation can create a huge environmental imbalance.

Explanation:

Answer:

Cause: Earth’s magnetosphere traps radioactive  solar wind particles in bands around Earth → Space travel through the Van Allen  belts is dangerous.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.

Answer:

Cause: Earth’s magnetosphere traps radioactive

solar wind particles in bands around Earth.

Effect: Space travel through the Van Allen

belts is dangerous.

Cause: Earth is surrounded by a magnetic field.

Effect: Solar wind deflects toward the poles.
