C. Offering business incentives for reducing use
D. Producing more fossil fuels
E. Rewarding reductions in current personal use
Answer:
b
Explanation:
as time goes on it could be possible with new found ways to never again need the fossil fuels
There are different kinds of investment. The option that is the most effective public policy in reducing reliance on fossil fuels in the long run is Investing in renewable fuel technologies.
Renewable energy sources is known to give the best way to fulfill the energy needs of the world. While fossil fuels is known to be soon depleted and therefore renewable energy sources are always there.
It is therefore smart to invest in renewable energy as the capability to store renewable power for use when needed makes it better than alternative to fossil fuels.
Investing in renewable energy stocks is known to helps man in spreading one's wings and can bring about a lot of dividend income.

true?
A. Jessica inherited both genes from her father.
I
B.
Jessica inherited both genes from her mother,
C. Jessica inherited one recessive form of the
gene from each parent.
D.
Jessica inherited one dominant form of the
gene from each parent.
Answer:
D
Explanation:
Dominant and the recessive allele are the traits present in the genes that get inherited from the parent to their offspring.
The trait that is visible in the phenotype is called dominant while the trait that gets masked in the proximity of the dominant allele is called recessive.
The correct answer is:
Option C. Jessica inherited one recessive form of the gene from each parent.
This can be explained by :
The genotype of Jessica's eyes = bb (light)The genotype of her parents = Bb (dark eyes)See the attached image below for the cross:
The genes gets independently assorted and Jessica inherits the recessive form of the genes from both of her parent.
Therefore, Jessica inherited recessive gene one from each parent.

Which distribution pattern do the oyster larvae exhibit?
O A. clumped
OB. stationary
C. random
OD. uniform
Answer:
D. Random
Explanation:
The term "population distribution pattern" refers to the method or form in which population of a certain organism living in a certain area occupy that area.
For example:
Uniform distribution pattern in which organisms are arranged in a equal or regular manner in the area. This gives a competition to the organisms of the area with reference to each other.
If we talk about Oysters, they are able to travel many and many kilometers across a certain area. Therefore, they don't stay at a place in a regular manner and this gives them random distribution pattern.

Explanation:
the large brown plate is pacific plate was under the ocean and also named after the ocean pacific ocean. so it is easy to guess
hope you understood it . it was my explanation up for more info down i have pasted what they told in google.
Pacific plate
In fact, six of the seven major tectonic plates are named after the continents they contain. The one exception is the Pacific plate, which lies beneath the Pacific Ocean. Not only is this the only major tectonic plate that is mainly underwater, it is also the largest, spanning over 100 million square kilometers.
Pacific Plate. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.
A student is measuring plant growth in an experiment. Using the same species of plant, he places one plant in the dark and one in artificial light. He
hypothesizes that, over time, the plant in the artificial light will grow larger than the plant in the dark. What is the dependent variable in this
experiment?
-Artificial light
-Plant growth over time
-Species of plant
-Time in light versus dark
Answer: Plant growth over time
Explanation:
i would say that because its very likely that the growth of the plant will change, the rest of them seem like a independent variable. Have a good day hope i helped.

how does the virus use a host cell to make copies of itself
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

BIOLOGY EXPERTS!!!! Shared core processes support the relatedness of all eukaryotes. Discuss how chromosome structure and function provides insights into the history of life on Earth.
Answer: Many eukaryotic organisms are related based on the shared core characteristics and processes.
Explanation:
The following are the shared core processes shared by all eukaryotes.:
1. Cytoskeleton: It is a network of structural proteins, that helps in movement of cell and organelle support.
2. Membrane-bound organelle: Mitochondria and chloroplast are organelles that formed via endosymbiosis these are present in all eukaryotic organisms.
The DNA is the basic genetic material that is found in almost majority of living beings on earth. The DNA is being transmitted from the primitive organisms on earth to the modern day organisms. The chromosomes are the carriers of DNA. These chromosomes are passed from the parents to the offsprings through reproduction. This is the basis of relatedness among organisms and these are also considered while studying the phylogenetic relationships.

Answer:
mitochondria are to produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.
Explanation:
the role of mitochondrion is to generate the energy commodity of the cell, by respiration, and control of cell metabolism.Mitochondrial is the ATP synthesis site for the cell. The amount of mitochondria present in a cell is also a strong predictor of the cell 's rate of metabolic activity; cells that are very metabolically active, such as hepatocytes, may have more mitochondria.

The populations living on a rough, steep mountain would have a higher rate of
speciation than those living in a large, open grassland because the mountain
would
A. show less habitat fragmentation
B. provide its populations with more resources
C. isolate populations into subgroups
D. have fewer niches for organisms
Answer:
The correct answer is option C, that is, have a wider range of environments.
Explanation:
It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.
A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.
In comparison to populations living in broad, open grasslands, populations living on rocky, steep mountains would experience a higher rate of speciation due to the mountain's ability to divide populations into smaller subgroups . So, the correct option is C.
How the population have higher rate of speciation?Geographic isolation is known to be a common way for the beginning of the process of speciation, similar to the formation of mountains, the alteration of rivers, the migration of organisms, and continental drift. As a result, what was once a stable population becomes divided into two or more different kinds of smaller populations.
A mountain range might result in a greater amount of speciation because to differences in precipitation and temperature as a result of various altitudes. A single mountain chain can display a huge variety of biodiversity and temperature zones as a result of these variances.
Therefore, the correct option is C.
