Answer:
“Geoneutrinos,” neutrinos that stream naturally from the Earth’s interior, are giving scientists the best direct evidence of what’s at work in the belly of the planet. Released by naturally occurring radioactive isotopes inside the Earth, geoneutrinos carry information about what makes the Earth’s insides hot; what elements make up the core of our planet and in what concentration and distribution; how the Earth’s mantle and tectonic plates move and interact; and how planets like our own form and evolve.
The gastrointestinal wall is composed of four layers or tunics:
- Mucosa
- Submucosa
- Muscularis mucosa
- Serosa
The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.
The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.

Answer:
The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria.
Explanation:
Answer:
More organisms are present on location A.
Explanation:
Due to more yearly precipitation, there is more vegetation present on location A. Due to the presence of this vegetation, more organisms are present because there is more food available for organisms as compared to location B. Due to less precipitation, there is less or no vegetation is present on location B and organisms are present in less number due to harsh environmental conditions and no food availability for organisms.
Answer:
The most appropriate answer would be "There is a lack of genetic variation for selection to act upon.".
Evolution is a gradual and natural process by which the characters of a population changes over several generations with the help of natural selection.
Reduction of population size up to 100 to 160 decreases overall genetic diversity of the population due to which the efficiency of natural selection decreases.
Consequently, the population of panthers may no continue to evolve.
