A pea plant from a pure-breeding strain that is tall, has green pods, and has purple flowers that are terminal is crossed to a p

lant from a pure-breeding strain that is dwarf, has yellow pods, and has white flowers that are axial. The F1 plants are all tall and have purple axial flowers as well as green pods. What proportion of the F2 progeny resulting from the self-cross of an F1 plant will resemble the dwarf parent from the parental generation?

F. Why are there more producers in the world than top carnivores?
Rainbow [258]

Answer:

There is only enough food for a few top level consumers

Explanation:

The organisms that eat the producers are the primary consumers. They tend to be small in size and there are many of them. The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. The secondary consumers tend to be larger and fewer in number. This continues on, all the way up to the top of the food chain. About 50% of the energy (possibly as much as 90%) in food is lost at each trophic level when an organism is eaten, so it is less efficient to be a higher order consumer than a primary consumer. Therefore, the energy transfer from one trophic level to the next, up the food chain, is like a pyramid; wider at the base and narrower at the top. Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

What is digestion? Starting from mouth, state the various steps involved in digestion <br>​
Sladkaya [172]
Mouth. Food starts to move through your GI tract when you eat. When you swallow, your tongue pushes the food into your throat. A small flap of tissue, called the epiglottis, folds over your windpipe to prevent choking and the food passes into your esophagus.

Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.

Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.

Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.

Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.

Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.

Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement

Blababa [14]

Answer:

1. DNA

2. RNA

3. Nucleus

4. Nuclear membrane

5. Nuclear pore

6. Nucleolus

7. Chromatin

Explanation:

DNA is present in nearly all living organisms. It has the capacity to replicate itself and also the capacity to be transcribed into RNA. The latter contains the genetic codes that are usually translated during protein synthesis.

The nucleus is the most prominent, membrane-bound (nuclear membrane) organelle in the eukaryotic cell. The nuclear membrane has a special pore, the nuclear pore, through which molecules can be transported between the nucleus and the cytoplasm.

Within the nucleus is the nucleolus, a spherical structure whose primary function is to make ribosomal subunits. The genetic materials in the nucleus are in the form of chromatin, a decondensed protein-DNA complex.
