zheka24 [161]

Answer:

b. Clean up plastic trash from shorelines, rivers, and other waterways that flow into the oceans.

Explanation:

Oceanic plastic garbage "patches" are a build up of debris most especially plastic, nylons, waste from wood that was deposited purposely or not purposely( by the wind or ocean waves) into the ocean.

Human activity that would most directly reduce the amount of plastic garbage that enters the ocean includes the cleaning up plastic trash from shorelines, rivers, and other waterways that flow into the oceans.

The extinction vortex represents the idea that even if an organism is extant, it may have a gene pool that will not support its
NISA [10]

Answer:

True.

Explanation:

Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.

Andru [333]

Answer: ecosystem

An ecosystem is a community of living and non-living components. A coral reef is an aquatic ecosystem which is formed by a continuous walls of calcium carbonates released by living animals they get combine to form rocks. These rocks and walls are collectively called as hard stony corals. These hard stony corals provide shelter to many aquatic animals like fishes. As the water is the chief abiotic factor along with coral walls and rocks which help in the survival of living organisms therefore, ecosystem is the largest organizational level found in one coral reef.

George Beadle concluded that teosinte is the likely ancestor of maize (corn), even though the two plants appear very different.
Oliga [24]

Answer:

Option B

Explanation:

ALL options are as follows -

a. teosinte and maize can produce fertile hybrids.

b. teosinte and maize have similar chromosomes.

c. Both Teosinte and maize have naked, soft kernel.

d. Teosinte and maize can produce fertile hybrids

Solution

Beadle started working on maize genetics since 1962 after joining graduate school at Cornell University.  

During his research he found that the chromosomes of teosinte and maize possess higher similarity and also show signs of intercross ability of the two species and hence confirmed that wild teosinte is an ancestor of domesticated maize.  

He later concluded that there are only 4 to 5 genes that make these two species different from each other rest all is similar.  

Option B is correct
