Which is a coarse-grained, igneous rock composed mainly of pyroxene, plagioclase feldspar, and olivine?

Answers

Answer 1
Answer: The answer is gabbro.

Gabbro is a group of rocks that are igneous and phaneritic (coarse-grained). It is formed when magma trapped beneath the surface begins to cool slowly. It consists of pyroxene, feldspar, plagioclase, and, in smaller ratio, olivine. Gabbro's common name is 'black granite'.

True or false? Rabbits are born blind.

Answers

The provided statement stating that the rabbits are born to be blind," is true.

Rabbits are born blind. At birth, their eyes are closed, and they rely primarily on their sense of touch and smell to navigate and locate their mother for nursing. It takes a few days for their eyes to open, and their vision gradually develops over the following weeks.

Rabbits are small, furry mammals belonging to the family Leporidae. They are herbivorous animals found in various habitats around the world, except for Antarctica. Rabbits have long ears, a compact body, and strong hind legs adapted for swift movement and jumping. Rabbits are popular as pets due to their small size, cute appearance, and relatively low maintenance requirements.

The answer would be true, yes. They are not only are born blind, but also born naked. "Naked" does not necessarily mean they are "naked", it is a term meaning that they can't see.

Which of the following best shows how primary structure relates to protein function? a. High temperatures cause proteins to denature.
b. Changing one amino acid in the protein hemoglobin causes sickle-cell anemia.
c. Proteins are sensitive to changes in pH.
d. The shape and chemistry of an enzyme's active site determine its function.

Answers

A.) High temperatures cause proteins to denature.

Final answer:

The sequence of amino acids, or the primary structure, in a protein determines its shape and function. Changing one amino acid in hemoglobin results in sickle-cell anemia, showing that small alterations in the primary structure can have significant impacts on protein function.

Explanation:

The primary structure of a protein is important in determining its function. It refers to the sequence of amino acids that make up the protein chain. The option that illustrates this relationship is b. Changing one amino acid in the protein hemoglobin causes sickle-cell anemia.

This statement is valid because the amino acid sequence (primary structure) determines the shape the protein takes. In the case of hemoglobin, a single amino acid substitution causes a significant enough alteration in shape to result in the harmful condition of sickle-cell anemia, thus clearly showing the link between primary structure and protein function.

Some types of organisms obtain needed energy through predation.
a. True
b. False

Answers

True

Heterotrophs obtain energy by feeding on another organisms like plants or animals. 

In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web.   

The Answer for that question is True.
