Answer:
B
Explanation:
A measure of the natural populations of algae, plants, fish, and other wildlife provides evidence of the health of a body of water.
BB, Bb and bb are examples of?
dominant
recessive
genotypes
phenotypes
BB, Bb and bb are examples of genotypes. Thus, the correct answer is genotype.
A genotype is the genetic constitution of a trait in an individual. It is the genotype that results in the particular phenotype. Phenotype is the observable result of the trait.
Capital letter indicates that the allele is dominant and for recessive allele, small letter is used. Thus, B indicates dominant allele of that trait and b indicates recessive allele for that trait.
Depending on the genotype, the individual can be homozygous dominant, homozygous recessive or heterozygous for a trait.
In this case, BB is for denoting homozygous dominant, Bb is for heterozygous dominant and bb is for homozygous recessive.

Answer:
UNA CADENA ALIMENTARIA ES LA RELACON ENTRE LOS MIEMBROS DE UN ECOSISTEMA PARA QUE UNA PARTE DE LA -ENERGIA- SEA TRANSFERIDA ENTRE ELLOS
ExplanatioN:
La cadena trófica es un procesos de tranferencia de energía entre distintos organismos de un ecosistema, en el cual cada organismo en un nivel se alimenta de organismos provenientes del nivel anterior y es comido por organismos del nivel siguiente. Los primeros eslabones de la cadena son autótrofos (fotoautotrofos o quimioautotrofos), productores que sintetizan la materia orgánica a partir de productos inorgánicos. Los eslabones siguientes son los consumidores heterótrofos: herbívoros, carnívoros, detritívoros.
Paso de energía entre niveles:
Del total de energía que llega a la superficie terrestre, solo el 1% es tomado por los fotoautótrofos. Esta energía adquirida que ingresa a la cadena trófica, tiene un recorrido unidereccional por donde pasa de nivel a nivel, desde los autótrofos hasta los heterótrofos, hasta que finalmente esa energia es disipada nuevamente en el ambiente.
Regla del 10%:
Esta regla establece que solo el 10% de energía utilizada por un nivel trófico pasa al siguiente nivel trófico. Solo el 10% de energía almacenada como biomasa en uno de los niveles tróficos, por unidad de tiempo, se convierte en energia almacenada del siguiente nivel trófico.
Esta progresiva reduccion de energía determina en número de niveles tróficos en esa cadena, que puede ser de cuatro o cinco eslabones.
Natalie accelerates her skateboard along a straight path from 0 m/s to +4.0 m/s in 2.5 s. Find her average
acceleration.
Answer:
[tex]a=1.6\ m/s^2[/tex]
Explanation:
Given that,
Initial speed, u = 0 m/s
Final speed, v = 4 m/s
Time, t = 2.5 s
We need to find the average acceleration of Natalie. We know that average acceleration is equal to the change in speed per unit time. So,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{4-0}{2.5}\\\\a=1.6\ m/s^2[/tex]
So, her average acceleration is [tex]1.6\ m/s^2[/tex].
When scientists compare molecular clocks between species, they
have to use the same segment of DNA. Which of these statements
would explain why that is necessary?
A. Not every segment of DNA mutates.
B. Different genes mutate at different rates.
C. Species accumulate neutral mutations at random rates.
D. All mutations cause harmful effects.
Check Answer
Answer:
ITS B: DIIFERENT GENES
Explanation:
Answer:
Yeah same here
Explanation:
The reason is mutation rates differ between species and even between different regions of the genome of a single species. These different rates of nucleotide substitution are measured in substitutions (fixed mutations) per base pair per generation.
If a 15 amp circuit has a 9V battery in it, how much power is being generated?
Answer:
P = 135 Watts
Explanation:
Given that,
Current in the circuit, I = 15 A
Voltage, V = 9V
We need to find the amount of power generated. The formula to find the electric power is given by :
P = VI
Substituting all the values,
[tex]P=9\times 15\\\\=135\ W[/tex]
So, the required power is 135 watts.

Question 1 (1 point)
Which of the following is a abiotic factor that could limit the growth of the plant population?
Grasshopper population
Sunlight
Fish population
Bacteria in the water
Answer:
Sunlight
Explanation:
Plants are autotrophs which makes their own food in the presence of sunlight and the process is called photosynthesis. Sunlight is very important for the process of photosynthesis.
So, the only abiotic factor from the options that could limit the growth of the plant population is sunlight. plants can not make their food without sunlight and no food means no growth of plant population.
Hence, the correct answer is "Sunlight".
what is the advantage and disadvantage of the Ocotillo and Hummingbird relationship
Advantages:
The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.
The relationship between Ocotillo and Hummingbird is an example of a mutualistic relationship, which means that both species benefit from each other's presence.
What are the various advantages and disadvantages of the relationship ?The advantages and disadvantages of this relationship can be described as follows:
Advantages:
Ocotillo provides a source of nectar for hummingbirds, which is an important source of energy for their high metabolic rate.
Hummingbirds are efficient pollinators of Ocotillo flowers, which helps to ensure their reproduction and genetic diversity.
Ocotillo provides a nesting site for hummingbirds, where they can raise their young in safety from predators.
Disadvantages:
The relationship between Ocotillo and hummingbirds is specific and may not be beneficial to other species of plants or animals.
Ocotillo is adapted to living in arid environments and may not provide a suitable habitat for some other species of birds or animals.
If the population of either Ocotillo or hummingbirds were to decline significantly, it could affect the survival of the other species in the mutualistic relationship.
Overall, the advantages of the Ocotillo-Hummingbird relationship outweigh the disadvantages, and this mutualistic relationship is an important part of the ecosystem in which they both live.

What does this article reveal about the role Black inventors have played in America's history? Explain your answer.
Answer:
The article revealed the fact that Black inventors have always played an active role in inventing new things in America. In the 18th and 19th centuries they were denied the right to patent their inventions because of their status as slaves. This has changed for the better in present times as many Black inventors are being granted patent rights.
Explanation:
The article, "America’s always had black inventors – even when the patent system explicitly excluded them", by Shontavia Johnson, explained the active role that Black Americans, both free and slaves played in inventing things in the United Slaves. The article explained that although the patent rights signed into the constitution in 1787 was written in a neutral tone, it did not change the fact that black inventors were actually denied patent rights.
This segregation affected people like Henry Boyd, Ned, Benjamin Montgomery among others. In recent times, this segregation has significantly been curbed as many Black inventors are now owners of patents. An example is Lonnie Johnson, inventor of the Water Gun and owner of more than 80 patents.
