Answer:

Explanation:
) The stem of a plant is growing upward while the roots grow downward. Which of these stimuli correctly describes the response of the plant?(1 point) touch light gravity temperature
Answer:
The correct answer is ''gravity.''
Explanation:
Tropisms are movements or changes in posture that a living being normally makes in response to a continuous environmental stimulus. Plants have hormones that respond to the gravitational impulse of our planet. Gravity deeply influences their growth and development (positive geotropism) and plants have been found to bend in response to gravity due to redistribution of the plant hormone auxin at the root tip, so that auxin is redistributed to the underside of a root that grows when it is rotated 90 degrees, the stems will still grow upward, away from the center of the Earth (negative geotropism), just as roots will always grow in the reverse direction (positive geotropism).
Answer:
The correct answer is gravity

Weathering is a process in the rock cycle. How does weathering contribute to the formation of rocks?
Here are the answers
It increases the temperature and creates metamorphic rock.
It deposits sediment and forms sedimentary rock.
It breaks down rock into smaller pieces that can become sedimentary rock.
It causes lava to cool and harden into igneous rock.
Answer:
It breaks down rock into smaller pieces that can become sedimentary rock.
Explanation:
Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
The process of weathering is very important for the formation of rocks because it breaks down rocks into smaller pieces.
By virtue of this, these tiny rock pieces called sediments are gathered and assembled together through erosion. They are then taken away and deposited in basins where they are transformed into sedimentary rocks. This is a very vital process in the rock cycle.when deforestation occurs in an area what immediate effect does this haveon the water cycle?
Answer:
When deforestation occurs, precious rain is lost from the area
Explanation:
Trees improve water quality by slowing rain as it falls to the Earth, and helping it soak into the soil. Trees then serve as natural sponges, collecting and filtering rainfall and releasing it slowly into streams and rivers. Tress are the most effective land cover for maintenance of water quality
1.If a DNA molecule has 40% Cytosine, what percent of it would be Adenine?
2.Please help describe the base-pairing rules in any DNA molecule
Answer:
The correct answer is -
1. Adenine - 10%
2. A-T and C-G always in DNA.
Explanation:
1. The total amount of all nitrogenous bases are equally 100% and which includes an equal amount of C and G and an equal amount of A and T in the DNA molecule.
So, Cytosine = 40%, Guanine= 40%
total = 80%
therefore, the A and thymine would be - 100 - 80 = 20
A+T = 20
A= 10, and, T = 10%
2. The complementary base pairing rule explains that DNA base pairs are Adenine always binds with thymine and cytosine bind with guanine only. Purine binds with pyrimidine always except - A-C or G- T.

There is more genetic variation ________________ a population that ________________ populations.
Answer:
1. Within
2. Among two different
Explanation:
There is more genetic variation WITHIN a population than AMONG TWO DIFFERENT populations. This is evident in the fact that phenotypic variation occurs at a greater length within a population resulting from natural selection based on survival and the ability to produce offspring strategy. This unlike populations that consist of two or more different populations mingled together.

What type of isotopes are termed radioactive isotopes?
The radioactive isotopes of an element are called radioisotopes.
The number of protons in the atomic nuclei of different isotopes of the same element is the same, but the number of neutrons varies. The radioactive isotopes of an element are called radioisotopes. They can alternatively be described as atoms with surplus energy in their nucleus or unstable neutron-proton combinations.An isotope will become radioactive if the neutron to proton ratio exceeds a certain threshold or the atomic number is higher than 83.According to the idea, an isotope will become radioactive if its atomic number is higher than 83 or if the neutron-to-proton ratio rises over one or becomes excessively large.Gamma rays, beta particles, and alpha particles are the three types of radiation that are released. Typical instances of radioactive isotopes are Arsenic−74, Iodine−131 and Cobalt−60.learn more about radioactive isotopes here: https://brainly.com/question/18640165

identify two processes that produce the basalt
Basalt rock formed on the cooling and crystallization of magma released from volcanoes.
What is basalt rock?The extrusive igneous (volcanic) rock known as basalt is black in color, low in silica content, and relatively high in iron and magnesium.
The most prevalent type of lava rock is basalt, which forms as magma, or liquid rock, and rises from the deep Earth at volcanoes. At several of the world's active rifts now, basalt is forming, including those in Iceland, the Red Sea, the East African Rift Valley, and the Rio Grande Valley in New Mexico and Colorado.
Basalt is used in construction (e.g. as building blocks or in the groundwork), making cobblestones (from columnar basalt) and in making statues. Heating and extruding basalt yield stone wool, which has potential to be an excellent thermal insulator.

B. a back and forth or up and down motion

C. a straight line of matter
D. a material that transfers energy
Answer:
B.
Explanation:
Which is not true?
Basaltic magma has a low viscosity and retains little gas.
Andesitic magma has both an intermediate gas content and explosiveness.
An increase in temperature increases a magma's viscosity.
An increase in silica increases the viscosity of magma.
Answer: An increase in temperature increases a magma's viscosity.
Explanation: Lower temperature magmas have higher viscosity than higher temperature magmas (viscosity decreases with increasing temperature of the magma).
The molten or semi-molten matter that is found underground and forms igneous rocks is called magma. It is very hot and is found in the lithosphere of the Earth's surface.
The answer is :
Option C. An increase in temperature increases a magma's viscosity.
This can be explained as:
The Basaltic magma has low gas content and viscosity because of this non-explosive eruptions occurs.Andesite magma has strong explosion forces and the gas content is intermediate.The greater degree of polymerization is due to high silica content.Therefore, an increase in the temperature does not increase the viscosity of magma.
