Answer:it’s A
Explanation:
Which type of plant tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant?
o dermal
ground
ОО
meristematic
vascular
Vascular tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant.
Vascular plant tissues in higher plants can be divided into phloem and xylem.These tissues (vascular) are fundamental to transport water and solutes to all tissues of a plant.Conversely, meristematic tissue is a type of tissue composed of undifferentiated cells.In conclusion, vascular tissue contains open vessels that transport water, ions, minerals, and nutrients throughout a plant.

When Went placed the agar block on one side of the decapitated shoot, the shoot curved away from the agar as it grew. This demonstrated that some kind of hormonal signal had diffused into the agar from the coleoptile tips. ... Went's experiment represented the first time that anyone had isolated a hormone from plants.

What was the genetic variation of dark moths and how did it occur?
Answer:
Natural Selection
Explanation:
A random genetic mutation gave rise to the dark colored moths. All types of living things have small differences between the individuals in the species. If one of those differences allows the individual to live longer, they will likely have more offspring. As that trait is passed on, the population starts to look more like a successful individual. Over time, the species changes.

A new dog breed is less likely to cause an allergic reaction in humans. Which statement explains how artificial selection led to the development of this desirable trait?
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dog breeds were chosen for nonallergic traits and bred with each other to obtain the new dog breed.
Dogs were trained over generations to not produce and release proteins that cause allergic reactions in humans to obtain the new dog breed.
Dogs were kept outdoors over generations to build up a natural defense against allergens in the environment to obtain the new dog breed.
Answer:it is c
Explanation:cuz it is
Answer:

1If you have 52.4 grams of hydrogen and 52.4 grams of helium, which one has a greater mass ? Why ?
Answer:
Hydrogen.
Explanation:
Hydrogen has greater mass and it's bigger than helium because as we move from left to right on the periodic table, atomic size decreases. Hydrogen atom is normally signified than H2 which is bigger than an atom of helium.
Also hydrogen has an atomic radius of 53pm while Helium has an atomic radius of 31 pm. Therefore the mass of helium is smaller than that of hydrogen.

O A. Student 1 believes Kingdom A ilmbacteria because it is unicellular and prokaryotic. Student 2 believes that kingdom B is plant because it is missing a cell wall and is multicellular. O B. Student 1 believes Kingdom A is fungi because it is autotrophic and unicellular. Student 2 believes that kingdom B is animal because it is eukaryotic and heterotrophic. C. Student 1 believes Kingdom A is animal because it is prokaryotic and unicellular. Student 2 believes that kingdom B is bacteria because it is unicellular and prokaryotic. O D. Student 1 believes Kingdom A is bacteria because it is unicellular and prokaryotic. Student 2 believes that Kingdom B is animal because it is eukaryotic and heterotrophic.
Answer:
It's the last answer choice
Explanation:
You basically look at the chart and see if the answer choices match.
A researcher recently discovered a new species of bacteria in the body of a tubeworm living near a hydrothermal vent. He compared the DNA of this new bacterial species to the DNA of four other species of bacteria. The DNA sequences came from the same part of the bacterial chromosome of all four species. According to these data, the unknown bacterial species is most closely related to
Answer:
That are more similar to each other.
Explanation:
The unknown bacterial species is most closely related to that bacteria which experience high temperature because both bacteria can live and survive in hot climatic conditions. The new species of bacteria and other four bacteria have some similar features due to similar chromosome but also have some differences due to difference in environmental conditions where they survived so those bacteria that have more similarities are more closely related to each other.
how much will atmospheric carbon change in 10 years
Answer:
Explanation:
Carbon dioxide is a greenhouse gas: a gas that absorbs and radiates heat. Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.
Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer. And while carbon dioxide is less abundant and less powerful than water vapor on a molecule per molecule basis, it absorbs wavelengths of thermal energy that water vapor does not, which means it adds to the greenhouse effect in a unique way. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.

Answer:
A.
Explanation:
A solar eclipse occurs when a portion of the Earth is engulfed in a shadow cast by the Moon which fully or partially blocks sunlight. This occurs when the Sun, Moon and Earth are aligned. Such alignment coincides with a new moon indicating the Moon is closest to the ecliptic plane.
Answer:
A
Explanation:
To see a total eclipse, where the moon fully covers the sun for a short few minutes, you must be in the path of totality. The path of totality is a relatively thin ribbon, around 70 miles wide, that will cross the U.S. from West to East.
