Which development in plants has contributed to the evolution of large trees?

Answers

Answer 1
Answer:

Answer:

Secondary vascular growth

Explanation:

Secondary growth in the plant allows them to be thicker, unlike primary growth that is apical. Secondary vascular cambium acts as a support for plants especially trees as they grow taller –allowing them to support their own weight. This is what is perceived as wood (secondary xylem) in a tree.

What is the best basis for analyzing/mapping evolutionary hostory​

Answers

Answer:

https://en.wikipedia.org/wiki/Phylogenetic_tree. Try this link.

Explanation:

The best basis for mapping evolutionary history would be a phylogenetic tree.  This "tree" shows the relationship between every biological species on Earth in reference to their origin...In evolutionary terms, a common ancestor. This tree also takes into consideration the genetic and physical traits and differences in every species and organism on the tree. Hope this helps : )!

well you should start maybe a time line OR,  In the case of phylogeny, evolutionary investigations focus on two types of ... a high percentage of bases in the same locations, causing these organisms to appear ... history of species, our own included, phylogenetic analysis has ... made recommendations for conservation

Which of the following practices that are needed to run a nuclear power plant has a negative impact on both air and water?a.
cooling of the power plant
b.
mining of uranium
c.
storage of radioactive waste
d.
monitoring the reactor

Answers

The correct answer is option B

The mining of uranium is harmful for both air and water. Uranium is a radioactive compound that is extracted by mining.

Uranium ore emits the gas named radon. The health effects of exposure to radon have particular problems. Significant rate of lungs cancer was observed during the 1940s and 1950s.

Water is used in the heap leaching of the uranium mining. The water can get mixed into the normal supply of water and harm the health of people.

Mining of the radioactive element Uranium has the following negative effects on both air and water such as contamination.

What is Uranium?

This is a a silvery-white metallic chemical element in the periodic table, with atomic number 92 and is commonly used to run nuclear power plant.

it exists in the air and when contaminates water could lead to kidneyailments in affected individuals which is why option B was chosen as the most appropriate choice.

A male pistol shrimp with protective eye tissue pockets mates with a female shrimp without protective eye tissue pockets. All of the offspring have eye tissue pockets. What is the most reasonable conclusion that can be made about the eye tissue pocket trait in pistol shrimp?

1Points
A
It is a recessive, autosomal trait.

B
It is a dominant, autosomal trait.

C
It is a trait that results from multiple alleles.

D
It is a trait that results from incomplete dominance.

Answers

I know only the last one and I think it’s B cause dominant trait is the trait observed in the first generation when parent with different traits are bred like Mendel’s first experiment
