Answer:

the elephants , the locusts, crown-of thomas starfish,cattle,common carp

Explanation:

Elephants are the world's largest and most powerful land animals, so it's not surprising they have a profound impact on the ecosystem.

The locust swarm of lore is one life phase of a type of short-horned grasshopper. It's a phase that can become a plague under the right conditions.

This large starfish gets its name from the venomous, long spines that cover its body. They live among and feed on coral polyps. When the species becomes overpopulated, it can destroy vast coral reef ecosystems. In fact, widespread destruction of the Great Barrier Reef is partly blamed on these sea stars, which have experienced a population explosion over the last decade or so.

According to the U.N. Food and Agriculture Organization, cattle farming is responsible for 18 percent of greenhouse gases. Cattle emit a large volume of methane through burping and flatulence. Cattle ranching is also a major source of deforestation around the world, most notably in South America's Amazon rain forest.

The common carp is a true bottom feeder, uprooting and disturbing submerged vegetation. These fish are notorious for altering their environment.

A test cross can be used to _____.

gtnhenbr [62]

Answer: - Predict an unknown genotype of a purebred dominant plant.

Explanation:

The genetic make up of the organism is called as the genotype. It describes the form of genes or allelic forms present in the organism. A test cross is used to determine the genotype of the organism. In this cross the organism with the unknown genotype is done with that of the organism with the known genotype. It also determines the fact that the organism is either homozygous dominant or hetrozygous.

On the basis of the above description, Predict an unknown genotype of a purebred dominant plant.

Which of the following statements represent evidence supporting the endosymbiotic theory? Check all that apply.

Tems11 [23]

Answer:

The statement that says " The mitochondrion contains a circular chromosome that has bacterial DNA sequences" is true among the all statement given above.

Explanation:

The Endosymbiotic theory that is other wise known as the symbiogensis illustrates the occurrence of the eukaryotic cell from the prokaryotic cells. Mitochondria and plastids are the most studied example in support of this theory. This theory explains that the aforementioned organelles are formed as they are taken inside in one another by the prokaryotic cell. Some of the evidences in support of this theory are mentioned below:

Phylogenetic similarity between the mitochondria and chloroplast to the proteobacteria and cynobacteria respectively.
Ability of these organelles to divide only through binary fission as the bacterial population.
The associated ribosomes are similar to the bacterial ribosomes.
Presence of porins in these organelles similar the bacterial membrane.

The cells in red bone marrow that produce blood platelets are called megakaryocytes, which can be

tia_tia [17]

Answer:

Limits platelets population.

Explanation:

The result of this modified cell cycle would be the presence of limited population of this cell because no mitosis occurs in these cells. Mitosis is a type of cell division that increases population of the cells. These megakaryocytes are changed into platelets by releasing protoplatelets that break up into a number of smaller and functional platelets. These platelets skip mitosis and cytokinesis process which limits their population in the body.
