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.
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

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.
photosynthesis
B.
formation of fossil fuels
C.
precipitation
D.
volcanic eruptions
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.

Answer:
D
Explanation:
Use the model of meiosis that you made earlier in the lesson to explain how crossing over contributes to genetic diversity. How did you modify your model? How do you think crossing over affects the expression of certain traits compared to the cells where crossing over didn’t occur?
Answer:
Due to exchange of parts of chromosome.
Explanation:
Crossing over is the exchange of segments or parts of chromosome between non-sister chromatids in the meiosis cell division. Due to crossing over, new combinations of genes in the gametes are formed that are not found in both parent which leads to genetic diversity. Crossing over affects the expression of certain traits in the organism because the organism that crossing over have different features as compared to their parents so there is a big difference between organism have crossing over and no crossing over.

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.

trait.
O Recessive
O Codominant
O Dominant
O Incomplete

O Dominant
Explanation:
An allele that is always expressed whenever it is present is called dominant. Mendel's law of segregation states that the two alleles for a trait segregate independently when gametes are formed.

Give two possible effects of an increase in global air temperature on living organisms
[2 marks]
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.
Explanation:
hope this help you
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.

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.

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.
