Answer:
density = Mass/volume
therefore, d= 13/5 = 2.6g/cm3
Explanation:
please change subject of your question next time, this is maths or phy not biology :-)
The density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.
What is Density?Density may be defined as a type of physical quantity that measures the degree of compactness of a substance. It may also be characterized as the substance's mass per unit of volume. The symbol most often used for density is ρ (row).
According to the context of this question,
The mass of a glass marble = 13 g.
The volume of a glass marble = 5 cm3.
The formula for calculating density is as follows:
Density = Mass/volume.Density = 13 g/5 cm3 = 2.6 g/cm3.
Therefore, the density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.

Which action would most likely increase the greenhouse effect?
Answer:
The correct answer is - B. burn more oil for heating homes.
Explanation:
Burning oil or fuels produce a high level of carbon dioxide which is a greenhouse gas and result in store in the atmosphere and does increase the temperature of the earth and increase the greenhouse effect. Nuclear power does not affect greenhouse gasses as it releases carbon dioxide same as a wind power plant.
The other two option helps in lowering the effect of the greenhouse effect on atmosphere or help in lower the greenhouse emmission.
Chemical energy stored in food molecules is released through
Chemical energy stored in food molecules is released through respiration.
What is cellular respiration?Cellular respiration is a sequence of chemical reactions which usually break down glucose to produce ATP, which can then be used as energy to power a variety of reactions throughout the body.
The cell, as we know, is the structural and functional unit of life, and each cell requires energy to function.
As a result, cellular respiration refers to respiration that occurs at the smallest level of our bodies, namely the cellular level.
Solar energy is harvested as chemical energy in photosynthesis, which converts water and carbon dioxide to glucose.
As a byproduct, oxygen is produced. Oxygen is used in cellular respiration to break down glucose, releasing chemical energy and heat in the process.
Thus, through respiration the chemical energy is released.

Match the human activity and how it increases the greenhouse affect
Answer:
1. primary cause of human-created carbon emissions = burning fossil fuels
2. destroys natural carbon sinks leading to more carbon dioxide in the air = deforestation
3. emits methane from decomposing matter = waste disposal in landfills
Explanation:
1. "Fossil fuels" are nonrenewable resources that are considered essential for the operation of many factories and industries. Burning them accounts for most of the carbon emissions on Earth, and this leads to "global warming."
2. "Forests" are considered "carbon sinks" because they have a role of absorbing the carbon dioxide in the atmosphere. Cutting down the trees (deforestation) makes forests barren. It then leads to more carbon dioxide in the air.
3. Waste disposals in landfills contribute to the amount of methane that is released into the atmosphere. Methane is considered a potent greenhouse gas that affects people's health.
Can epigenetic changes influence an organism its entire life?
Answer:
The methylation of DNA and other epigenetic marks do not alter the genes that they influence at a sequence level but nonetheless alter the expression of these genes. Furthermore these marks can be acquired throughout the lifetime of the individual and, if carried in their gametes, these marks are inheritable.
What type of
deformation
DOES NOT result
in an earthquake?
A. fracture
B. plastic
C. shear stress
D. elastic
Answer:
a. fracture deformation
A fault is a crack or region of cracks that separates two rock blocks. The blocks might move in relation to one another due to flaws. This movement may happen suddenly, like an earthquake, or it may happen gradually, like a creep. Thus, option A is correct.
What is fracture deformation in earthquake?Simply said, fractures are places in the crust's crust where there is no movement. According to the relative movement that occurs along a fault, faults are categorized.
Strong evidence supports the fracture hypothesis of earthquakes, given the close resemblance between earthquakes and fractures.
Earthquake occurrence stochastically, the relationship between earthquake size and frequency, and the mechanism underlying different earthquake sequence patterns.
Therefore, Deformation results from plate tectonic forces and gravitational forces.

Answer:
Respiratory system - breathing is faster, lungs open up to take in more air
Nervous system - heart rate speeds up, senses become sharper
Muscular system - body moves to a safer space
Circulatory system - stress hormones are transported around the body
Explanation:
Organ systems are groups of organs that work together to perform a certain function in the body. The human body consists of eleven organ systems. Four of them are included in the question you were given.
The respiratory system is the system of organs that allow us to breathe. It includes the airways, lungs, and blood vessels.
The nervous system is the organ system that coordinates our behavior and transmits signals between different parts of our body. It consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.
The muscular system is the organ system that permits movement of the body, maintains posture, and circulates blood throughout the body. It consists of skeletal, smooth, and cardiac muscles.
The circulatory system is the organ system that carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide. It consists of the blood, blood vessels, and heart.
Based on this information, we can conclude what function belongs to which organ system.

How did the Everglades wetlands become drier?
More water was used to irrigate out-of-state farms than could be replenished by rainfall
Dam and canal building forced water into underground aquifers to expose wetlands
Climate change caused water in the Everglades to evaporate
Dam and canal building diverted the historical flow of water away from the Everglades.
Answer:
The correct answer is - Dam and canal building diverted the historical flow of water away from the Everglades.
Explanation:

Scientists can “edit” sequences of DNA by locating and replacing certain nucleotides. Explain how and why these edits will have consequences on the resulting trait.
Answer:
Gene editing can be used to modify DNA sequences at target genes, thereby regulating proteins encoded by them
Explanation:
Gene editing refers to the methodologies used in molecular genetics to discretionally modify the DNA sequence of targeted cells. Since genes control phenotypic features by specifying the synthesis of specific proteins, these methodologies have the potential to alter specific traits. Recently, a gene-editing methodology called CRISPR-Cas9 has emerged as a versatile programmable gene-editing system which can be used to easily change the DNA both in-vitro and in vivo. This gene-editing system has been adapted from a naturally occurring genome engineering system existent in bacteria.

C. Multiple Allele
D. Polygenic Inheritance
Answer:
tbh i think its D
Explanation:
i say its D cos why not and i dont have enough brain cells for this
Answer:
It should be D, Polygenic Inheritance.
Explanation:
If you look up the definition of Polygene, it says "A polygene or multiple gene inheritance is a member of a group of non-epistatic genes that interact additively to influence a phenotypic trait." Examples of Polygenic Inheritance are described as skin color, eye color, hair color, body shape, height, and weight. Also, since poly means multiple, it wasn't too hard to assume that "polygene" means multiple genes working together. Hope this helps!
