What is the main factor that causes bedrock to weather at different rates?
1. Elevation above sea level
2. Mineral composition
3. Age of rock layers
4. Environmental factors
Answer:
2. Mineral composition
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Minerals is any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Hence, mineral composition is the main factor that causes bedrock to weather at different rates.
When is genetic drift a major factor in evolution?
O A. When there is low gene flow
O B. When there is high selective pressure
O C. When there is sexual selection
O D. When there is female choice
Answer:look at pic
Explanation:
When there is high selective pressure is the major factor in evolution.
What is Genetic drift?Genetic drift is the arbitrary change in the population's frequency of a gene variant that already exists. Gene variations may totally vanish due to genetic drift, which would limit genetic diversity. Moreover, it can make previously uncommon alleles far more common and even fixed.
Genetic drift is an evolutionary process in which the frequency of a given gene allele varies randomly across a population.
The impacts of genetic drift can be severe, often causing traits to become excessively common or to vanish from a community, even though it predominantly affects small, isolated populations.
Therefore, When there is high selective pressure is the major factor in evolution.

Roosting areas in buildings of any height are the _________ of species 1.Roosting areas in buildings of any height are the _________________ of both bat species.____________ between the two bat species occurs because both species prefer the same roosting areas.In parts of the city with only tall buildings (over two stories), __________ of species 1 may occur.Roosting areas in buildings that are one to two stories tall are the __________ of species 1 when species 2 is present.a. fundamental niche
b. realized niche
c. character displacement
d. intraspecific competition
e. interspecific competition
f. (-\-)
g. resource partitioning
h. competitive exclusion
Answer:
Roosting areas in buildings of any height are the fundamental niche of species 1.Roosting areas in buildings of any height are the fundamental niche of both bat species.Interspecific competition between the two bat species occurs because both species prefer the same roosting areas.In parts of the city with only tall buildings (over two stories), competitive exclusion of species 1 may occur.Roosting areas in buildings that are one to two stories tall are the realized niche of species 1 when species 2 is present.Explanation:
The ecological niche is the synthesis of all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The fundamental niche refers only to environmental conditions in which a species can live and survive in the absence of any interaction with other species. The realized niche refers to the restricted conditions in which a species can live and survive as a result of environmental physic characteristics and the interaction with other species.Interspecific competition refers to the interaction between two or more species that use the same fundamental niche. These species compete for the same resources like food, shelter, or water, among many others. Eventually one of the species dominates and the other is displaced. Competitive exclusion refers to the exclusion of the inferior competitor by the superior competitor when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective niche of the dominant species completely occupies the fundamental niche of the inferior competitor. Resources partitioning refers to one dominant species monopolizing the resources, and the other inferior species use other resources -partially or completely -, migrate or get extinguished.A way in which species can divide resources is by living in different habitat areas. These species might eat the same food, and can roost in different places within the habitat. This resource partitioning and differentiation in the function of their physical location allows both species to coexist more effectively.
In the present example, both bat species can coexist in the same city but the weaker bat species (species 1) roost at the top of the shorter buildings while dominant species (species 2) roost at the top of the highest buildings.
How would the population of this type of plant be affected if the bee
population decreased dramatically?
A. Because the plants depend on the bees as a food source, the plant
population would decrease.
B. Because the plant would not reproduce as effectively, the plant
population would decrease.
C. Because the two organisms are of different species, the plant
population would be unaffected by the change in the bee
population.
D. Because the bees would no longer prey on the flowers, the plant
population would increase.
Answer:
Option B - because bee act as a medium for the plant for fertilisation due to which plant reproduce but if the population of bee decrease this will affect the rate of reproduction in plants.
The population of this particular type of plant be affected if the bee population decreased dramatically because the plant would not reproduce as effectively, and the plant population would decrease. Thus, the correct option is B.
What is Population?A Population may be defined as the group of individuals belonging to the same species living in the same area at a given time. This represents the members of the same species in a definite area.
The population of bees is significantly necessary for mediating the process of pollination that involves the mechanism of sexual reproduction in plants.
But if the population of bees is reduced due to any factor, this plant does not undergo the process of pollination which ultimately leads to the reduction in the population of this plant as well.
Therefore, the correct option for this question is B.

Write out the steps in the Central Dogma. List where each step occurs in the cell. For each arrow, name the process that the arrow represents and the primary enzyme (complex) respon- sible for completing that step. Name the step(s) in which mRNA, tRNA, and rRNA have a role and briefly describe the role of each in the step(s) you name.
Answer:
1. The Central Dogma refers to the molecular process by which the DNA is converted into proteins using RNA as intermediate, i.e., DNA (Transcription)-> RNA (Translation) -> Protein.
2. Localization:
Transcription: within the cell nucleus (in eukaryotic organisms)
Translation: cytoplasm
3. Enzymes :
Transcription: RNA polymerase
Translation: Peptidyl transferase
Explanation:
Transcription is the process by which a segment of DNA (called gene) is used as template to synthesize a messenger RNA (mRNA) by using a specific RNA polymerase enzyme. During translation, this mRNA travels from the cell nucleus to the ribosomes in the cytoplasm, where this sequence (mRNA) is used as template to synthesize a protein. The ribosomes are organelles composed of ribosomal RNA (rRNA) molecules which direct the catalytic steps of protein synthesis, while transference RNAs (tRNAs) are molecules that act as adaptors which link the mRNA template with the corresponding amino acids being incorporated into the protein. The enzyme peptidyl transferase catalyzes the formation of peptide bonds between adjacent amino acids.

The autonomic nervous system is the main function of our arterial cell function in our body.
In prokaryotes, transcription and translation can happen simultaneously because
a. DNA and mitochondria are both located in the nucleus
b. DNA and ribosomes are both located in the nucleus
c. DNA and mitochondria are both located in the cytoplasm
d. DNA and ribosomes are both located in the cytoplasm
In prokaryotes, transcription and translation can happen simultaneously because DNA and ribosomes are both located in the nucleus. Therefore, option B is correct.
The ribosomes are responsible for protein synthesis. They are also found in the cytoplasm of prokaryotic cells. The ribosomes read the mRNA produced during transcription and directly synthesize proteins using the information encoded in the mRNA.
The absence of a nuclear membrane in prokaryotes allows for the coupling of transcription and translation to occur in close proximity in the cytoplasm.

Even though the idea of recycling materials and using them in other ways seems like a good idea, why is the idea of using recycled tires at playgrounds a concern for some scientists?
edge2021
Answer:
The idea of using recycle tires at playgrounds is a concern for some scientists because they contain carcinogenic substances.
Explanation:
Recycle tires are in playgrounds as rubber mulch. This one is on the playground's floor to cushion the impact of any falls that kids may have while playing. The problem with this product is that, as they are old tires cut into little pieces, they still have the tires' toxins such as arsenic, benzene, cadmium, mercury, etc. Exposure to these toxins can cause cancer. This is why some scientists are concerned with this material in areas where kids are exposed to it since they are more vulnerable to carcinogens than adults.
