Plants get the nitrogen they need to create amino acids and DNA - option D. Option B and option C are correct.

Plants get nitrogen which is essential to form amino acid and nucleic acid that is DNA. Plants can not get the nitrogen gas directly from the air therefore, the process called nitrogen fixation takes place.

Thus, the correct answer is - option D. both B and C are correct.

Water us important to out planet because almost every animal and plant needs water to survive.

Explanation:

Water has been the most crucial molecule that supports life on earth. It is a most important solvent that makes up the majority of living organisms and is involved in cellular activities.

Water has been defined as the most crucial molecule that supports and benefits the living organism. They are the abiotic factors that all the biotic factors depend on for their growth and development.

All the activities involved with survival have been dependent on water to sustain all the living functions and reactions. It is important for the planet as it is involved in all spheres and biogeochemical cycles. It is the elixir that carries life forward.

Therefore, water is the most important for humans, other organisms, and the planet.

Answer:

A sample count is the data from a sample, or a small group. A total count would be the data from the entirety of whats being studied, not just a sample.

A lot of researchers often perform a total count or a sample count in research. The difference between sample count  and total count is that a total count is done when the whole study area is surveyed but a sample count is done only when parts of the study area are surveyed.

The results obtained from those parts are used for the whole study area to approximately know the total population size.

Wildlife sampling methods often uses different methods of estimating animal numbers or densities. they are direct counts of population units, and indirect counts and indices.

Wild animals are very difficult to count as all  animals are never distributed evenly within the sample area and there may be fluctuations.

Mouth. To more easily absorb different foods, your saliva helps break down what you're eating and turn it into chemicals called enzymes.

Esophagus

Stomach

Small Intestine

Large Intestine, Colon, Rectum and Anus.

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion like the tongue, salivary glands, pancreas, liver, and gallbladder.the Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.

Our body needs food to provide it with energy, vitamins, and minerals. However, in order use food, we must first break it down into substances that the various organs and cells in our body can use. This is the job of our digestive system. The digestive system acts in stages to digest our food. Each stage is important and prepares the food for the next stage. The entire length of our digestive system is around 20 to 30 feet! Here are the major stages of the digestive system:

1. Chewing - Chewing is the first stage of the digestive system. When you chew your food it breaks up big pieces into little pieces that are easier to digest and swallow. Also, your saliva is more than just water. It has special enzymes in it that start to break down starchy food (potatoes, bread) while you chew.

2. Swallowing - Swallowing may seem like a simple process to us. It just sort of happens. But food doesn't just fall down our throats into our stomach. First, our tongue helps to push food into the back of our throat. Then there are special throat muscles that force the food down into a long tube that leads to our stomach, called the esophagus. The food doesn't just fall down the pipe, muscles push the food along until it gets to our stomach. At the same time all this is going on, a flap blocks off our windpipe making sure food doesn't go the wrong way. We call this "going down the wrong pipe" and it can make us choke. This flap is called the epiglottis and, fortunately for us, it works automatically.

3. Stomach - The next stage is the stomach. Food hangs out in the stomach for around four hours. While the food sits there, more enzymes go to work on it, breaking down things like proteins that our bodies can use. The stomach kills a lot of bad bacteria as well, so we don't get sick. 4. Small Intestine - The first part of the small intestine works with juices from the liver and pancreas to continue to break down our food. The second part is where the food gets absorbed from the intestine and into our body through the blood.

5. Large Intestine - The last stage is the large intestine. Any food that the body doesn't need or can't use is sent to the large intestine and later leaves the body as waste.

6.The Liver and Pancreas The liver and pancreas do a lot to help the digestive system along. Both work with the small intestine. The liver provides bile (stored in the gall bladder) that helps break up fat into smaller bits. The pancreas provides additional enzymes to help digest all sorts of food. The liver also processes the digested food from your blood before it gets sent to various places in your body to be used.

Fungi are eukaryotes and have a complex cellular organization. As eukaryotes, fungal cells contain a membrane-bound nucleus where the DNA is wrapped around histone proteins. Fungal cells also contain mitochondria and a complex system of internal membranes, including the endoplasmic reticulum and Golgi apparatus

HOPE THIS HELPED <3

Answer/Explanation:

Somewhat like animals, Fungi need oxygen and eat dead organisms in order to survive. A fungus may look like a plant, however it gets energy from living of dead plants and sometimes other fungi. Fungi need a moist area to live with plenty of oxygen making rotted out trees a perfect place to grow.

Fungi are eukaryotes and have a complex cellular organization. As the fellow answerer above said, it has mitochondria and cell membranes that are artistically arranged. Unlike plants, they do not have chloroplasts nor chlorophyll.

Half-Life is the time for a substance (U-235 in this case) to decay to 1/2 its original mass.

Since the problem is asking for the time for U-235 to decay to 1/2 its original mass (100 grams to 50 grams) then the decay time is 1 half-life, or 700 million years.
