the four kinds of cell communication (between two different cells) based on the distance from source to receptor are: direct contact, signaling, signaling, and signaling.
The four kinds of cell communication (between two different cells) based on the distance from source to receptor are: direct contact signaling, paracrine signaling, autocrine signaling, endocrine signaling.
What is autocrine signaling?When a cell releases a ligand that binds to receptors on its own surface, it is signaling to itself in an autocrine manner or autocrine signaling (or, depending on the type of signal, to receptors inside of the cell). Although doing this may seem strange for a cell, autocrine signaling is crucial for numerous activities.
For instance, autocrine signaling plays a crucial role in development by assisting cells in assuming and maintaining their correct identities. From a medical perspective, autocrine signaling is significant in cancer and is believed to be crucial for metastasis. A signal frequently binds to the sender cell as well as other nearby cells that are comparable, having both autocrine and paracrine effects.

Using food pyramids, explain why a vegetarian diet is more "ecologically responsible."
The responsibility to preserve and protect the environment is known as ecological responsibility. The majority of the time, ecological responsibility is related to businesses making sure that their operations always abide by environmental laws and regulations.
Explain about vegetarian diet is more Ecologically responsible?People can drastically minimize their consumption of land, water, and oil resources as well as the amount of pollution they might otherwise generate by selecting a vegetarian diet rather than one high in animal products.But when the study's 153 vegans, vegetarians, and omnivores were all included in, it became clear that eating meat was, on average, worse for the environment. When we think about food crops, there are other broad issues to keep in mind that could have a greater negative influence on the ecosystem.According to a thorough peer assessment of studies on vegetarianism, a non-meat diet will probably result in a person emitting less carbon dioxide than they would with a meat-based diet—roughly 1,200 pounds less carbon dioxide. That translates to a mere 4.3% reduction in emissions for the average person living in industrialized nations.

(the human genome has a total of 6.4x 109 nucleotides)
Answer:
46 origins
Explanation:
there were no time constraints on replication, one origin would be required for each chromosome; thus, a minimum of 46 origins, equal to the number of chromosomes in a human cell, would be needed.
More energy can be from fat molecule than from glucose molecule because the fat molecule contains more
Answer: Hope this helps.
Explanation: Triglycerides store about twice as much energy as carbohydrates. Triglycerides are made of glycerol and three fatty acids. Because there are so many carbons in three fatty acids, and each 2-carbon unit can enter the citric acid cycle, one fatty acid molecule can generate much more ATP than one molecule of glucose.

What is Woese's tree of life?
This is a unique research program developed by Carl Woese, it is based on rRNA, for discerning bacterial relationships and constructing a universal tree of life. Woese's interest in the evolution of the genetic code led to him to investigate the deep roots of evolution, develop the concept of the progenote, and conceive of the Archaea.
The tree indicates that the common ancestor for eukarya and archaea is more recent than the common ancestor for all three domains.
Eukarya are therefore more closely related to the archaea than is to the bacteria.

Some individuals are unable to digest the lactose found in the milk of cows. The digestive systems of these individuals most likely lack which of the following?
A.
a lipid that coats lactose molecules
B.
an ability to produce lactose internally
C.
an enzyme that catalyzes lactose breakdown
Some people cannot digest the lactose found in milk. This person's digestive system is deficient in any of the following. The ability of the body to produce lactose.
Sugar is found in milk. It is a disaccharide containing glucose and galactose units. When a person with lactose intolerance consumes dairy products, lactose from these components can enter the intestines and cause gas, cramps, bloating, and diarrhea. Some people can eat small amounts of dairy without any problems. Others have stomach problems and want to avoid all dairy products. Signs of lactose intolerance include nausea, cramps, gas, bloating, or diarrhea within 30 minutes to 2 hours after drinking milk or dairy products. Symptoms occur because the scaffold does not produce enough lactase to digest the ingested lactose.
Lactose is one of the main components of human and animal milk. As a disaccharide containing glucose and galactose, lactose has a fortifying effect on milk. Eggs are not mammals and come from birds, including chickens, ducks, or quails that do not currently produce milk. Eggs are rich in protein and contain many essential vitamins and minerals. They no longer contain lactose, so they can be eaten by people with lactose intolerance and who are allergic to eggs.

Why do scientists think gases such as CO2 trap heat in the atmosphere?
Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can trap heat. Greenhouse gas molecules in the atmosphere absorb light, preventing some of it from escaping the Earth.
Carbon dioxide is Earth's most important greenhouse gas that works for absorbing and radiating heat. Greenhouse gases absorb heat radiating from the Earth's surface and even circulate it in all directions including back toward Earth's surface.
Carbon dioxide in the atmosphere warms the planet, causing climate change. Human activities have raised the atmosphere's carbon dioxide content by 50% in less than 200 years.

Article of plastic in the ocean.
Why or how does the article occur ?
Also provide a brief personal reflection on the article that you have given me
Earth's last sink for plastic waste, the oceans, receive the majority of it from the land. Major rivers operate as conveyor belts, gathering up debris as they flow downstream and carrying it to the ocean. Many pieces of plastic waste that are floating at sea stay in coastal waters.
Why is plastic in the ocean happening?Plastic garbage is transported through drains, streams, and rivers by wind and rain. Ocean access is via drains! Another significant factor is careless and incorrect garbage disposal; unlawful rubbish dumping significantly contributes to the plastic pollution of our oceans.Being such a persistent contaminant, plastic waste is particularly harmful. Decomposition of plastic products might take hundreds of years. Both people and animals are at risk from this garbage.

Perma frost is referred to an area which is located on land or under the ocean in areas where there is a low concentration of oxygen as result of certain factors and properties.

Chaparral is a type of woodland that is characterized by a combination of dry soil, warm weather, and short and hardy shrubs. The chaparral biome is dominated by short types of woody plants instead of grasses that are present in the grassland biome or tall trees which are present in forest biomes. The chaparral is unique and present on the Pacific coast of North America. Chaparral is a temperate biome that is characterized by hot-dry summers, and mild and rainy winters. Nearly all of the rainfall occurs in the winter and spring rainy seasons at the Chaparral.
