What is a possible reason for extinction?
The number of habitats falls below a critical level.
Too many resources
Less competition
Less number of new predators
Answer:
The number of habitats falls below a critical level.
Explanation:
The possible reason for extinction is that the number of habitats falls below a critical level. This makes it impossible for organisms to survive.
A habitat is the dwelling place of living organism in an ecosystem. The resources and other materials that ensures the survival of an organism are made available in the habitat. When a habitat begins to thin out and can no longer support organisms, then extinction will ensue.how are hydrogens ions (H+) essential fr the production of atp
Answer:
Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H+, is therefore customarily used to represent a proton.

Answer:
Only active transport requires ATP
Explanation:
Passive transport is the movement of molecules across the cell membrane without the need for energy. These substances usually move from a high concentration to a low concentration.
Active transport relies on energy from ATP to move substances across the plasma membrane. This is usually required when moving substances against their concentration gradient.
Which of the following is NOT a correct statement for plant tissue sampling procedures?
O Plant tissue samples should be free of soil particles
O The samples should be taken between mid-morning and mid-afternoon
O Taking any plant part for sampling is acceptable
O Rainy weather should be avoided when taking samples
Answer:
The answer is C: Taking any plant part for sampling is acceptable.
Explanation:
I have Agriculture and I took the test and I get the answer wrong the first time, but it told me the right answer after I got it wrong and it said that it was this.
During plant tissue sampling any plant part for sampling is not acceptable.
What is plant tissue sampling?Sampling of the plant tissue is an essential component of a crop fertility program. The analysis of the plant sample is generally done to see whether the crop is taking the nutrients appropriately or whether the plant is suffering from any kind of deficiency.
At the time of plant tissue sampling, one should not sample dust or soil contaminated tissue, that is, it should be free of soil particles. One should keep in mind that generally sampling is done between mid-morning and mid-afternoon.
The sample should be free from any kind of moisture, therefore, rainy weather should be avoided. During plant tissue sampling, any part of the plant is not sampled, generally the leaves or petioles of the plant is sampled for analysis.
Thus, the incorrect statement is the third one, that is, taking any plant part for sampling is acceptable.

Answer: Liver and then Fatty Acids
Explanation: Because I got it right on the test.
Bile salts, which are necessary for the emulsification and absorption of fats in the small intestine.
What is bile juice?Bile juice is a yellow-green liquid that is produced in the liver and stored in the gallbladder. It is made up of bile salts, cholesterol, and waste products such as bilirubin. Bile helps in the digestion and absorption of fats in the small intestine. It works by emulsifying fats into smaller droplets, which increases the surface area available for enzymes to break them down.
Bile also helps in the absorption of fat-soluble vitamins, such as vitamins A, D, E, and K. Bile is released into the small intestine in response to the hormone cholecystokinin, which is secreted when fatty foods enter the stomach. Inadequate production or secretion of bile can lead to problems with digestion and absorption of fats, such as diarrhea, malnutrition, and deficiencies of fat-soluble vitamins.

Are different dog breeds different species? Why or why not?
Answer:
They are the same species.
Explanation:
Full question: How come some similar animals are different species, while with domestic dogs, wildly dissimilar types are considered different breeds?
-- Z. Kornberg, Jerusalem
Michael Bruford, a professor of biological sciences at Cardiff University in Wales, explains the thought process behind this seeming double standard.
Scientists have been distinguishing between species on the basis of how they look, behave or live since recorded history began. However, two famous scientists stand out in terms of how we perceive species differences today: Carl Linnaeus, an 18th-century Swedish naturalist, and Charles Darwin. Linnaeus was the first person to formulate a single approach for describing species in a hierarchical manner according to their similarity, using his binomial nomenclature of genus followed by species (Homo sapiens, for instance). Darwin was among the first people, and certainly the most celebrated among them, to develop a credible theory on how species evolve (via natural selection). Both of these scientists' insights underpin most of what modern science utilizes when studying species and speciation.
Currently species are still primarily distinguished by their appearance, but it is becoming very clear that looks don't always tell us all we need to know about whether two organisms are different. Many so-called cryptic species exist that, to the untrained eye, look very similar or even identical to another organism--commonly found, for example, in nocturnal mammals such as bats and bush babies. If the two mated, however, they may never be able to produce viable offspring; this, in fact, is the primary criterion for dividing similar organisms into different species. Because of these red herrings--and also because the process of describing species is very long and labor-intensive--scientists are increasingly turning to DNA to assist them in identifying and describing species.
