Explanation:

The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers.

What is ACTN3 protein?

Although having one or two variant forms of the ACTN3 gene does not have any harmful effect, an individual's ACTN3 genotype does affect their athletic ability.

The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers. These types of skeletal muscle are responsible for generating force at high velocity.

Individuals lacking the variant gene have the R/R genotype whereas those possessing the mutation can have either one (R/X genotype) or two (X/X genotype) copies of the variant gene. This variant form of the ACTN3 gene is very common in the general population.

Therefore, The ACTN3 gene encodes the alpha-actinin-3 protein which is present in fast-twitch muscle fibers.

The Guam rail is a flightless bird found on the island of Guam. It builds a shallow nest on the ground and lays eggs throughout the year. There are no native species of snakes in Guam, so the Guam rail had no experience with snake predators until the brown tree snake was accidentally introduced sometime between 1944 and 1952. These snakes, which eat a wide variety of animal species, quickly established a large population on Guam.
How was the Guam rail most likely affected by the introduction of the brown tree snake?

A) The brown tree snake ate only species that lived in trees, so it had no effect on the Guam rail.
B) The Guam rail quickly developed the ability to fly in order to escape from the brown tree snake.
C) The population of the Guam rail declined, and the species nearly became extinct. D) The Guam rail began to build its nests in trees.

Answers

C- The population declined.

Explanation: B and D are wrong because the bird is flightless. A is wrong because there’s nothing that says the snake only eats species that live in trees. Therefore, B is the answer.
The answer is c. The popular of the Guam rail declined and the species nearly became extinct.

Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so, they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells, including the synthesis of fatty acids, membrane lipids, ...

Phtosynyhsis.

The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet's living systems are powered by this process

Seeds.

Seeds serve several functions for the plants that produce them. Key among these functions are nourishment of the embryo, dispersal to a new location, and dormancy during unfavorable conditions.

Roots.

Root, in botany, that part of a vascular plant normally underground. Its primary functions are anchorage of the plant, absorption of water and dissolved minerals and conduction of these to the stem, and storage of reserve foods.

Thus, An ecosystem is a region where different species of plants, animals, and other organisms coexist in harmony with the environment, including the climate and geography.

An ecosystem is a place where several types of living things coexist to create a bubble of life, including plants, animals, and other species. Ecosystems are made up of both biotic (or alive) and abiotic (or nonliving) components. Plants, animals, and other living things are considered biotic factors. Rocks, temperature, and humidity are examples of abiotic variables.

In an ecosystem, every component is dependent on every other component, either directly or indirectly.
