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.

A zebra eats grass and a lion eats the zebra what tropic level is the grass
Grass is at the first trophic level of the trophic system, they are the primary producers.
• The feeding positions of all the organisms in a particular ecosystem is known as the trophic levels.
• The base or the first trophic level of an ecosystem exhibits the higher energy concentration.
• The trophic levels illustrates that what the organisms eat. There are five trophic levels, that is, from simple plants to the ap-ex predators.
• In the first or the lowest level of the trophic system comes the primary producers, that is, the grasses and plants. They can be either aquatic or terrestrial.
Thus, in the given case, grass is the first trophic level of the ecosystem.

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.

There are giraffes that show an incomplete dominance in neck size. A giraffe with a tall
neck (TT) is crossed with a giraffe with a medium neck (TS). What fraction of giraffes will
also be tall?
25%
O 75%
O 50%
100%
Answer:
50%
Explanation:
(TT) Is fully tall. (TS) Is medium. So it can be assumed that (SS) is short. When forming a cross, you cross TT and TS to generate a phenotypic ratio of 1x1 or a genotypic ratio of 1 TT, 1 TS. Making it exactly split in half in 50/100.

A child is born to parents that both have hypophosphatemic rickets, a disease that is caused by a sex-linked dominant trait. What is the chance that the child will have the disease if the mother is heterozygous for the trait?
75%
50%
25%
100%
Answer:
75%
Explanation:
Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates) or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.
When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.
As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).
This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.
If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.
If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.
Hair color is a trait that’s controlled by many genes working together. Each gene contributes to this trait only in a small proportion. Which pattern of inheritance is this?
A. codominance
B. Incomplete dominance
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!

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:
To settle Florida the early settlers wanted to drain the everglades, they wanted to create agricultural land for farming by digging canals and building a dam to divert the flow of water of historical everglades.
They make and diverted the dam and big canals to flow the ocean and clear swamp waters of the everglades. Which made the everglades drier.

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.
