Which of the following statements about DNA (deoxyribonucleic acid) is NOT true?
Answer:
D
Explanation:
From the early 1700s to the modern day, how did various lines of evidence refine scientists’ understanding about the ancestry of Cetaceans?
a. Anatomy
b. Fossils
c. Embryological development
d. DNA (including amino acid sequences)
The various lines of evidence refine scientists’ understanding of the ancestry of Cetaceans by Fossils. So, the correct option is B.
What do you mean by Fossils?Fossils may be defined as the preserved remains, or traces of remains, of ancient organisms. It is the dead and organic remains of past organisms.
To estimate the ancestry of Cetaceans, which are categorized under marine mammals, scientists need to study their fossils, if possible. Because fossils reveal the evolutionary history in a better way.
Therefore, the various lines of evidence refine scientists’ understanding of the ancestry of Cetaceans by Fossils.

What are examples of things that can cause mutations?
Answer:
Exposure to chemicals.
Explanation:
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations. Hope this helped. :D

Answer:
The cell’s membrane separates the cytoplasm, forming two cells.
Explanation:
Cytokinesis is the physical process during cell division that separates the cytoplasm of the parental cell into two different daughter cells. Cytokinesis occurs after the telophase of mitosis. During this process, the cell membrane grows to surround each daughter cell and thus separate them. In animal cells, cytokinesis occurs by a ring of contractile microfilaments that lead to the constriction of the parental cell.

The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. The fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of ________. hormones plasma protein electrolytes glucose
Answer:
plasma protein.
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
Glomerular capsule is also referred to as Bowman's capsule and it can be defined as a cuplike sac (structure) with a double wall, which makes up the tubular part of a nephron within the kidney of mammals. It is saddled with the responsibility of first filtering blood (ultrafiltration) under pressure to generate urine in the mammalian kidney.
Plasma comprises of about 97 percent of water by volume and it typically contains mineral ions, glucose, carbon dioxide, hormones, plasma protein, etc.
Hence, the fluid in glomerular capsule is similar to plasma except that it does not contain a significant amount of plasma protein.
Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose father had blue eyes. Figure out each member’s genotype
Answer:
Man: Bb
Man’s mother: bb
Woman:Bb
Woman’s father: bb
Explanation:
Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.

Answer:
Heat waves can be dangerou, causing illnesses such as heat cramps and heat stroke, or even death. Warmer temperatures can also lead to a chain reaction of other changes around the world. That’s becuase increasing air temperatures also affects the ocean, weather patterns, snow, ice, and plants and also animals.

The two possible effects of an increase in global air temperature on living organisms are as follows:
It destructs the habitat of the aquatic ecosystem. It creates a serious cause of numerous diseases like heat stroke, heat cramps, etc. What are the causes behind increasing the global air temperature?The causes behind increasing the global air temperature are as follows:
Cutting down trees due to urbanization and industrialization. Excessive usage of carbon-based fuels. Liberation of greenhouse gases in the atmosphere.An increase in global air temperature almost affects each organism on the earth's surface. Plants are also threatened by the loss of water through stomatal pores. Due to high air temperature, the temperature of rivers, seas, oceans, ponds, etc also increases. As a result of this, the organisms living in those regions have been impacted a lot.
Therefore, the two possible effects of an increase in global air temperature on living organisms are well described above.

What conditions might cause the most water and sediment to be collected at the bottom of the stream table?
Answer:
Silent stream having uniform velocity cause the most water and sediment to be collected at the bottom of the stream table
Explanation:
A silent stream having uniform velocity allows the sand, soil, mud and dust in it to settle down and continuously flowing through various terrains (as governed by the law of precipitation).
If the stream water is moving at high speed and there is lot turbulence then the suspended particles in it will never settle.
Carbon is transferred from the geosphere to the atmosphere by natural processes and human activities. Which of the following processes contributes to the transfer of carbon to the atmosphere?
A.

The processes which contributes to the transfer of carbon to the atmosphere are formation of fossil fuels and volcanic eruptions.
What is carbon cycle?The cycle in which transfer of carbon to the atmosphere from the Earth and back into the atmosphere is called carbon cycle.
Carbon is transferred from the geosphere to the atmosphere by natural processes and human activities.
Let's check all the options one by one-
A. Photosynthesis- This is a process through which the plants transfer light energy into chemical energy. In this process, carbon move from atmosphere to the biosphere.B. Formation of fossil fuels-The fossil fuels are developed by decomposing plants and animals in a million of years. This decomposition contributes to the transfer of carbon to the atmosphere.C.Precipitation- Precipitation is the product of water cycle, which falls by gravitational pull from clouds.D. Volcanic eruptions-The product such as lava and the gases which are released by a volcano is called the volcanic eruptions. These eruptions add carbon to the atmosphere.Hence, the processes which contributes to the transfer of carbon to the atmosphere are formation of fossil fuels and volcanic eruptions.

Explain how many ancient and medieval societies forwarded marine science even though they were not specifically addressing issues in marine science.
Answer:
Marine life is the study that investigates the plants and animals of the water environment; it is also known as " aquatic biology, " " water science, " And " life oceanography. " the better studies the marine plant and animal experience found in bays, harbors, wetlands, and other water and coastal regions.
Answer:
Many ancient and medieval societies advanced marine science through their exploration, trade, and navigation activities, even though they were not specifically addressing issues in marine science. For example, ancient seafaring civilizations such as the Phoenicians, Greeks, and Romans developed sophisticated navigation techniques, shipbuilding methods, and trade networks that required a deep understanding of the ocean's physical and biological processes. Similarly, medieval societies such as the Vikings and the Chinese developed advanced shipbuilding technologies and navigational instruments that allowed them to explore and trade across vast distances. These activities required knowledge of ocean currents, tides, and weather patterns, which contributed to the development of marine science as a field of study. Additionally, many ancient and medieval societies also recorded observations of marine life, ocean currents, and weather patterns, which provided valuable insights into the ocean's physical and biological processes and helped to advance marine science.
