Answer:Biodiversity refers to the variety of life forms and ecosystems found on Earth. It encompasses the incredible range of organisms, the different species that exist, and the various habitats in which they live. Here are three key components that encompass biodiversity:
Explanation:
Species Diversity: This refers to the variety of different species in an ecosystem. It includes the number of species present, as well as their relative abundance. For example, a forest with a diverse range of trees, plants, birds, insects, and mammals would have high species diversity. On the other hand, a desert with fewer plant and animal species would have lower species diversity.
Genetic Diversity: This aspect of biodiversity focuses on the genetic variation within a species. It is the result of differences in the DNA of individuals within a population. Genetic diversity is crucial for the survival and adaptation of species to changing environments. For instance, a population of plants with diverse genetic traits may be more resilient to diseases or climate change compared to a population with limited genetic variation.
Ecosystem Diversity: Ecosystems are made up of communities of organisms and their physical environment. Ecosystem diversity refers to the variety of different ecosystems or habitats present in a region. These could include forests, grasslands, wetlands, coral reefs, and more. Each ecosystem supports a unique set of organisms and plays a specific role in maintaining the balance of nature. For instance, a coral reef ecosystem provides habitat for a diverse range of marine species and helps protect coastal areas from erosion.
B) Being around humans represented an advantage, so wolves were able to take advantage of that by changing their digestion to be able to eat wheat, rice, barley, corn, and potatoes.
C) Dogs mutated to be able to eat wheat, rice, barley, corn, and potatoes.
D) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.
Answer:
The correct answer will be option-D
Explanation:
The studies done by the scientist led to the conclusion that the doges were evolved from the wolves,
The interaction of the wolves with humans became symbiotic around 10000-15000 years ago when the wolves in search of food changed themselves and adapted to survive with humans.
The studies on the genes of Dog shows that the gene responsible to digest carbohydrate called amylase starting duplicating in Wolves allowing them to digest carbohydrate cereals offered by humans. Their pancreatic enzymes also got modified to digest the carbohydrate-protein rich cereals.
Thus, option-D is the correct answer.
As frequency goes up, wavelength does down
Light has frequency but no wavelength
Light has wavelength but no frequency
Answer:
False
Explanation:
Blood pressure is inversely proportional to vessel resistance
Yes, it is true that blood pressure is directly proportional to vessel resistance. As vessel resistance increases due to narrowing of blood vessels, the heart has to exert more force, leading to an increase in blood pressure.
The statement that blood pressure is directly proportional to vessel resistance is true. Blood pressure is a measure of the force that your heart uses to pump blood around your body.
When vascular resistance (the resistance that must be overcome to push blood through the circulatory system and create flow) increases due to narrowing of the blood vessels, the heart has to work harder, which results in increased blood pressure. Therefore, it's a direct relationship: as vessel resistance goes up, so does blood pressure.

Answer:
(C).Rough endoplasmic reticulum
Explanation:
Endoplasmic reticulum (ER) is a membrane-bound cell organelle, present in eukaryotic cells. There are two types of endoplasmic reticulum, smooth ER and rough ER.
Rough ER contains ribosomes on its outer surface (side, which is in contact with cell cytosol), while in smooth ER surface, ribosomes are absent. This is because ribosomes provide platform for the process of protein synthesis or translation.
Proteins synthesized by ribosomes present in rough ER surface are then transported to it (rough ER) for sorting and post-transnational modifications.
Thus, the correct answer is option (C).
Answer:
The ecological Niche is a function of a species serve in its ecosystem; including what it eats, and how it behaves.
If you don't understand, here is another explanation.
The ecological niche is about an organism living in an ecosystem with biotic and abiotic and how it behaves with it.
