Answer:
Stabilizing Variation.
Explanation:
This is the type of variation that occurs when genetic diversity decreases as the population of organism in a particular population based on a specific trait.
Organisms with varied or specific traits within the population are selected against by the selection pressure, with little chances of reproduction, while organisms in between, ( with least variation of this particular traits) which are within the narrow range, survive to reproduce.Thus, this gives rise to narrow population of these particular organisms,(stabilizing variation) which are therefore naturally selected.
Therefore, the variation of the organisms in this population is kept close to the centre of the same mean value.
In ecology, what is meant by the term "community"?

Si cruzamos dos individuos homocigotos de cobaya, uno negro y otro blanco, y sabemos que el carácter negro es dominante sobre el blanco. Su descendencia tendrá la siguiente características
Answer:
The offspring will be black because they are heterozygous for a dominant trait that is controlled by monogenic inheritance.
Explanation:
Guinea pigs will be heterozygous because they inherit a dominant allele that encodes for the black color and a recessive allele associated with the white color. Heterozygosity is a genetic condition associated with the presence of two alleles at a locus which are inherited from both parents, one from the mother and the other from the father

Select the living organisms that will decrease as a result of the loss of coral in the food web.
Answer:
Butterfly fish, Triggerfish, parrotfish, and sharks
Explanation: Because the first three fish listed feed on coral, their populations will decrease if coral is eliminated because that means there will be less food to go around for the populations to consume. Many will die out. If those fish die, there will be less of them for the sharks to eat, causing the shark population to decrease as well.

Species Y and Z are not related to humans.
Species X and Z are related to humans.
Species X and Y are related to humans.
Answer:
Species X and Y are related to humans.
Explanation:
The chart shows information about three different embryos early in their development. The best supported by the information in the chart is that Species X and Y are related to humans. Thus, option D is correct.
What is an embryo?An embryo refers to the early development stage with respect to the multicellular organism. The organism should be again produced se-xually. Moreover, the development of embryonic should be a portion of the life cycle just done after fertilization and continued via when the structure of the body is formed like tissues and organs.
The development of embryonic i.e. used for proof with respect to evolution should be related species that contain the same embroys.The similarities during the embryo stage of development among different animals are due to the expression of ancient genes.
These ancient genes have the same evolutionary origin, thereby they are homo-logous sequences. For example, fish embryos and human embryos express certain homo-logous genes in the embryos stage, thereby leading to the development of gill slit during this stage.
Therefore,Thus, option D is correct.

The pH of a solution determines the charge of certain R groups. The pH of pineapple fruit ranges from 3.5 to 5.2. Predict the effect on the activity of bromelain if it is used in a product with a pH of 11.
Answer:
The activity of Bromine will reduce
Explanation:
Bromine is found in pineapple stem with pH range of 3.5- 5.2 this implies that the environment where bromine is found is acidic hence when taken to a product whose pH is 11 which is basic then its performance will be low because its can only function well in an acidic medium.
pH ranges tell whether a substance is acidic, basic or neural.
Acid range from 3.5-6
7- neutral
8 above is basic
This is about knowing the behaviour of some elements in different PH Values.
The activity of bromelain will decrease in a product with a pH of 11. .
We are told that the PH of pineapple fruit is of the range of 3.5 - 5.2. In reality, this also includes it's stems and the plants as well. This falls into the acidic range because PH less than 7 is acidic.Now, these stems, plants and fruits of pineapple usually contain bromelain. This implies that bromelain does its' work in an acidic environment since pineapple has an acidic PH.If bromelain is used in a product with a PH of 11, it means it is being used in a basic environment because a PH greater than 7 indicates a basic nature. This means bromelain will not function as well as it did in the acidic environment and as such the activity of bromelain here would decrease.We can now conclude that the activity of bromelain will decrease in a product that has a PH of 11.

What feature is the same in the formation of many sedimentary rocks and fossil fuel?many sedimentary rocks and fossil fuels-
A-require material to be buried and exposed to heat amd pressure.
B-are made out of organic material that stores the sun energy
C-form where there are frequent earthquakes and volcanic activity
D- are produced high in the mountains where temperatures are low
Answer:
maybe C i'm so sorry if this is wrong
Explanation:
Organic materials and silt build on top to produce fossil fuels. Heat and pressure transform organic materials into coal, petroleum, or natural gas. Therefore, option (A) is correct.
What are fossil fuels?An extracted and burnt fossil fuel is a hydrocarbon-containing substance that naturally originated in the Earth's crust from the remnants of extinct plants and animals. Coal, oil, and natural gas are the three primary fossil fuels.
Because certain sedimentary rocks contain trapped fossil fuels, sedimentary rocks and fossil fuels are connected. As organic materials and silt build up on top over time, fossil fuels are created. The organic material undergoes a chemical shift under heat and pressure, turning it into coal, oil, or natural gas.

How can scientists investigate the impact of limiting factors on a population?
Answer: No population can increase without limitation. Instead, populations in natural ecosystems increase or decrease in response to the changes in the factors that restrict growth. Many factors influence population densities and growth, and these factors may lead to oscillations in population size over time. It is also often difficult to determine the exact factor limiting growth. Many different factors may combine to produce unexpected results.
Explanation: I hope this helps....
Answer:
Limiting factors include a low food supply and lack of space. Limiting factors can lower birth rates, increase death rates, or lead to emigration. Limiting factors determine the carrying capacity of a population.

An active transport process by which a vesicle moves a large substance out of the cell is known as __________.
osmosis
endocytosis
exocytosis
diffusion
Answer:
I'm pretty sure it is exocytosis. Because exocytosis transports vesicles out of the cell through the plasma membrane. Remember it as "exo" = exit.
Answer:
C. Exocytosis
Explanation:
The first thing we notice is that the question says "active transport". Looking at the answer choices, we see that "osmosis" and "diffusion" are options.
However, remember that osmosis (the diffusion of water from high to low concentration) and diffusion (the movement of particles from high to low concentration) are both passive transport; in other words, they don't require an input of energy. So eliminate them.
Now look at endocytosis and exocytosis. "Endo" means "inner", so "endocytosis" means the cell is engulfing a substance and bringing it inside. However, we want the process where a substance is moved out.
"Exo" means "out", so "exocytosis" means to expel something. That matches here, so our answer is C.
