The study of the gene is called genetics. Genes are always present in pair form.
The correct answer is DNA.
What is DNA?The DNA stands for deoxyribose nucleic acid.it stores all the genetic information and helps in the regulation of the formation of protein and hormones.In DNA, Adenine binds to the thymine and uracil in RNA.
In the question, it has the thymine nitrogenous base.
Hence, we can say that nucleic acid is DNA.

the diagram shows a model of how a hydra reproduces by budding
Answer:
B. It shows offspring that have the same genes as the parent.
C. It shows asexual reproduction.
Explanation:
Hydra reproduces by budding which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.
why does the illumination of the moons surface appear to change when viewed from earth even through the sun continuously illuminates half of the moon?
Answer:The revolution of the Moon around the Earth makes the Moon appear as if it is changing shape in the sky. This is caused by the different angles from which we see the bright part of the Moon's surface. These are called "phases" of the Moon.

You learned in the reading that some symbiotic relationships are helpful and some are harmful. Look at the symbiotic relationships listed below and select all where at least one organism is harmed (the reading calls these harmful relationships). Group of answer choices Commensalism Parasitism Mutualism Predator-Prey Competition
Answer: Parasitism, Predator-Prey, Competition
Explanation:
The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.
4. Genes that are responsible for new characteristics that help a species survive in a particular environment
are most likely to do which of the following?
A. rapidly decrease in frequency
B. gradually decrease in frequency
C. increase in frequency
D. not change in frequency
Answer:
The correct answer is - increase in frequency.
Explanation:
According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.
According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.

The air bubbles and spongy texture of bread are due to which process?
a. Lactic acid fermentation
b. Glycolysis
c. Alcoholic fermentation
d. The Krebs Cycle
Answer:alcoholic fermentation
Explanation:
The air bubbles and spongy texture of bread are a result of the process of baking of bread through alcoholic fermentation. Thus, the correct option is C.
What is Fermentation?
During fermentation, carbon dioxide is produced in cell and it is trapped as tiny pockets of air within the dough. The production of carbon dioxide causes the dough to rise.
During the baking of bread, carbon dioxide expands and causes the bread to rise further. In this process, alcohol is produced during fermentation which evaporates during the baking process of bread. In this process, yeast eats the sugar and releases carbon dioxide which causes air bubbles.
Therefore, the correct option is C.

Frida wants to measure the volume of a stone. The correct volume is B
The volume of the stone is 26 mL.
What is volume?
The initial volume = 473 mL
The final volume = 499 mL.
The final volume − Initial volume
= 499 − 473
= 26 mL.
Therefore, Frida wants to measure the volume of a stone. The correct volume is B .The volume of the stone is 26 mL.

Fragments of rock or lava that are sent into the air in a volcanic explosion are called
A) fumaroles
B) tephra
C) aggregates
D) cations
E) soil peds
Answer:
Fragments of rock or lava that are sent into the air in a volcanic explosion are called tephra.
Explanation:
The volcanoes come in different shapes and sizes, and with them come different types of eruptions as well. Some volcanoes have explosive eruptions, some mainly release ashes and gasses, while some erupt with lava flows. The volcanoes that have explosive eruptions release a lot of pyroclastic material often propelled high and wide around them.
Part of the pyroclastic material that is released is the tephra. Tephra is basically represented by fragments of very hot rock and lava that are shoot into the air during a volcanic eruption. The tephra is extremely dangerous, as it can be shoot out over a distance of several km, and being very heavy, very hot, and moving at very high speed, when it hits something it manages to destroy it or cause enormous damage, and if it is a living organism that is hot it will mean the end of it for sure.
Answer:
Tephra
Explanation:
Definition: rock fragments and particles ejected by a volcanic eruption.

How have trees adapted to survive through the cold winter months?
Answer:
Adaption
Explanation:
Adaptations. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold.

Which chemical weathering processes rely primarily on water? Select the two correct
answers
oxidation
hydrolysis
dissolution
precipitation
Answer:
hydrolysis and dissolution
Chemical weathering frequently involves the presence of water, whether it is in liquid or solid form, hence options B and C are correct.
What is chemical weathering?For instance, water in liquid form can seep into the fissures and cracks of the rock. The water will freeze if the temperature falls far enough, water expands as it freezes. Hydrolysis is a well-known kind of chemical weathering.
Chemical weathering is an erosive process in which chemical processes break down rocks and other materials (predominantly by water and chemicals dissolved within it).
When water comes into touch with rocks, the minerals that make up those rocks break down into individual components.
Therefore, as compounds in rock interact with water during hydrolysis, a new solution (a combination of two or more substances) is created, hence options B and C are correct.
