Answer:
In DNA there are 4 bases (adenine,guanine,thymine and cytosine)
adenine match with thymine while guanine match with cytosine.
RNA also contains 4 bases(adenine,guanine,uracil and cytosine)
adenine match with uracil while guanine match with cytosine.
In DNA, adenine pairs with thymine and guanine pairs with cytosine. In RNA, adenine pairs with uracil and guanine pairs with cytosine.
Explanation:The nitrogen bases in DNA and RNA are called 'nitrogenous bases' because they contain nitrogen atoms in their structure. In DNA, the four nitrogenous bases are adenine (A), guanine (G), cytosine (C), and thymine (T). In RNA, the bases are adenine (A), guanine (G), cytosine (C), and uracil (U).
Purines and pyrimidines are two types of nitrogenous bases. Purines, such as adenine and guanine, have a double-ring structure, while pyrimidines, such as cytosine, thymine, and uracil, have a single-ring structure.
Each base pairs with a complementary base. In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C). In RNA, adenine (A) pairs with uracil (U), and guanine (G) pairs with cytosine (C).

What term is used for the study of non living parts of earth?
A. Chemistry
B. Geology
C. Ecology
D. Biology
Correct option is B. The study of nonliving parts of Earth is called geology, a physical science that focuses on the solid aspects of Earth and other celestial bodies.
Physical Science and Earth's Nonliving Components
The term used for the study of nonliving parts of Earth is geology. Geology is a physical science field that focuses on the solid Earth, the rocks of which it is composed, and the processes by which they change. This contrasts with biology and ecology, which study living components and their interactions with the environment. Chemistry, while part of the physical sciences, focuses on the composition, structure, properties, and change of matter. Therefore, the correct answer to the question is B. Geology.
Understanding geology provides insights into Earth's history and is essential for various applications such as resource extraction, environmental protection, and studying the solid features of celestial bodies. It's an integral part of physical science, along with other fields like astronomy, physics, and chemistry, which together contribute to the comprehensive study of nonliving matter.

A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
B. No. Evidence for evolution comes only from body structures, not the environment of organisms.
C. Yes. Evolution occurs only in certain locations on Earth, and not others. D. No. Fossils and living species are distributed evenly across all of Earth's land and water.
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
Answer:
A. Yes. Patterns in the distributions of fossils and living species are useful evidence of evolution.
Explanation:
Data shows that presence or the absence of the continents and the islands provides evidence of the descent and shows us the specification of species. As the same species would be found in the same habitats that are capable of supporting a particular species in a geographical area as Africa or South America. Evidence have also been found in Australia that has marsupials like the kangaroos and quills that were not present in Africa and in small numbers in south America. Similarly, the fossils are found in areas know adjacent to each other and through the process of the continental drift, they diverged in wide geographical areas.This food chain can be found in the coastal waters of Virginia

Which of the following shows an unsaturated fatty acid?
Answer:
C
Explanation:
Unsaturated fats that chains in their polymer chains as shown in the diagram in C. These kinks reduced the levels of compaction between adjacent polymer chains because they disrupt the hydrogen bonds between the chains . Therefore, the oils will not be solid at room temperature. This is why they are called unsaturated fats.
Answer:
Option (C).
Explanation:
Fatty acids may be defined as the compound containing long hydrocarbon chains with the carboxylic acidic group. Two main types of fatty acid are saturated and unsaturated fatty acid.
Unsaturated fatty acids contains the double and triple bond in its structure. The option (C) in the picture contains the carboxylic acid with long hydrocarbon chain and double bond in its structure.
Thus, the correct answer is option (C).
the diagram below represents the time a cell spends in the two main phases of the cell cycle. what is happening in the phase represented by the yellow area?
D) the cell is dividing
Answer:
The correct answer will be option-D.
Explanation:
The cell cycle is the sequential steps of events which explains the duplication of the genetic material and division of the cell into daughter cells.
It usually takes place in 24 hours where it is divided into four phases: Gap 1 (G₁), Synthesis phase, Gap 2 (G₂) and Mitotic phase (M phase). M phase can be marked easily as it takes place during the short period of time usually in one hour.
In the given question, the marked area represents the shortest phase or M phase during which cell divides its nucleus and cytoplasm, therefore, is considered the cell division phase.
Thus, option-D is the correct answer.

Which object would have a larger gravitational force acting upon it
Answer
Hi,
An object with the largest size will have a large gravitational force acting on it. Explanation
The gravitation force increases with increase in size of an object. An object that has twice as much mass will exert two times as much gravitational pull on other objects. An object with greater mass attracts the earth more strongly that the other one with smaller mass. On the earth’s space, the more massive objects will exert stronger gravitational forces.

Explanation:
The planets closest to the Sun are the inner, or terrestrial, planets and are similar to Earth in some ways. They are rocky and dense, have few moons, no rings, and are relatively small. These planets also differ in many ways, as shown in the chart. For example, Venus is the hottest planet on the chart, even though Mercury is closer to the Sun. The temperature difference between Venus and Earth is significantly greater than the difference between Venus and Mercury, even though Venus lies close to midway between those two planets. Which statement elaborates on the cause of this wide range of temperatures between terrestrial planets?
The correct answer is - the atmosphere.
All of the terrestrial planets have atmospheres, but all them differ in their composition and density too. Venus has the highest temperature of the terrestrial planets, higher even then Mercury despite being closer to the Sun, because it has very dense atmosphere. Also, the key moment with the dense atmosphere of Venus is that it is mostly composed of carbon dioxide. The carbon dioxide is a gas that has the ability to trap the solar radiation into the atmosphere, so the more there is from this gas, the hotter it will be, and Venus has exactly that.

what conditions create the largest waves in the ocean enter your answer in the space provided please help !!!
fast-moving wind over smooth water
:)
Answer:
Moving winds on the surface of the ocean creates waves in the ocean.
The gravitational pull of the Moon causes the largest tides in the ocean.
Explanation:
Generally, the most common factor that causes the largest waves in the ocean is winds. this is also called wind-driven waves of the ocean when the surface wind flows on the surface of the ocean, this disturbance creates the friction between surface wind and surface of the ocean which creates waves in the ocean.
sometimes these winds create larger waves in the ocean but it depends on two factors such as "wind speed" and "wind duration".
The faster the wind, the larger the wave.

Place the steps of the respiration process in the correct order
1) Pulmonary Ventilation
Movement of air in and out of the lungs passage (Thorax and Diaphragm).
2) External Respiration
Exchange of gases between air and blood at pulmonary capillaries (Alveoli).
3) Transport of gases through blood vessels
O2 and CO2 carried in blood associated with RBC's.
4) Internal Respiration
Exchange of gasses between blood and body cells at systemic capillaries. O2 out of the blood, CO2 into the blood.
5) Cellular Respiration
Breakdown of molecules at mitochondria within cells to form ATP, this uses up oxygen and produces CO2 as a by-product.
Answer:
(1) Air enters the nostrils.
(2) Air passes through the trachea to the bronchi.
(3) Air diffuses from the alveoli to the blood cells.
(4) Oxygen enters the blood cells.
(5) Blood transport oxygen to other cells.
Explanation:
The steps of respiration process are:
(1) Breathing or air inhale and exhale also called pulmonary ventilation.
(2) External respiration: external respiration exchanges gas between the lungs and the blood stream. Oxygen is exchanged for carbon dioxide waste to the process called external respiration.
(3) Internal respiration: In this process gases are exchanged between the blood stream and body tissues.
(4) Cellular respiration: It is a process in which sugar breakdown into a form that the cell can use as energy.
which area would have the highest salinity
Answer: high rates of evaporation
Salinity is the measure of amount of salt dissolved in the water. The area with a plenty of run off will have very low salinity as the run off will take away the surface particles might be containing salt in it. The area with high rates of precipitation will have very low salinity this is because of the fact that the rainfall will take away the salts present on the surface to other location because of water erosion.
The area with high rates of evaporation will have highest salinity because the water or other liquid components gets removed from the surface leaving behind all the solid sediments which may also include salts.

what evidence do scientist find in the fossil record that suggests there was a big extinction event that occurred 66 million years ago?
Scientists continuously find fossilized bodies of dinosaur bones that all appear to have died the same way. It is because of these discoveries that we know that dinosaurs and other pre-historic species existed on Earth 66 million years ago.
The evidence that points to the fact that there was a big extinction about 66 million years ago lies in the fossil records themselves.
Records and evidence show that for an estimated two hundred and thirty million years, Earth was home to lots of dinosaurs. Fragments of their skeletons such as teeth, bones, etc have been found on fossils which corroborates this position.
The interesting thing however is that when subjected to radiocarbon dating none of the dinosaur remains were in age, less than 66 million years. This can only mean that there was a massive catastrophe that wiped out life as it existed then.
There is also some evidence that suggests that a huge asteroid impacted the earth at that time causing the extinctions.
