Answer:

In nature, the logistic growth model is more common.

Because interaction between species and the environmental conditions needed for an exponential growth model are not always possible. In fact, they are hardly possible.

Explanation:

This model states that there is unlimited resource availability. As there are guaranteed resources and space, there is no competition. Population growth does not depend on density, nor Natality and mortality rate. There is constant growth, which is proportional to the population size. The exponential growth model is represented by an exponential curve.

In nature, this is almost impossible. Just a few organisms, such as bacteria species, might be represented by this model. But in most species, this is not feasible because available resources are not infinite, space is not infinite, and there is always an interaction between species that affects their population sizes.

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.  

The logistic growth model is represented by a sigmoid curve. In the beginning, the population grows slowly. Its size N is inferior to K.In the second stage, the population size increases rapidly but N, is still inferior to K. Gradually, the population reaches the equilibrium point, K, which depends on resource availability. N equals k.  Resources become harder to find, and much of the living space is unavailable. Finally, when N is superior to K, the population must decrease in size because there are not enough resources to maintain that size.      

Species have different strategies to survive in different environments, reproduce, disperse, and compete. These strategies are r strategies and k strategies.  

"r" species: Their growth rate per capita is very high, which makes possible the colonization of new environments. These species are mostly small-sized organisms with short life cycles. They reach sexual maturity at early stages and have numerous offspring. They hardly spend energy in parental care. Many "r" species exhibit the exponential growth model, but not all of them.        

"k" species: Their growth rate per capita is low. They are often big-sized and long-lasting species.  They reach sexual maturity in advanced stages and do not have numerous offspring. They spend much time of their lives in parenting to ensure reproductive success. They are important competitors, being capable of displacing other species and monopolizing the available resources. "k" species exhibit the logistic growth model.  

Answer:

C

Explanation:

The most likely outcome of such an event is negative as it threatens local biodiversity. Therefore, option (C) is correct.

The variety and variety of life on Earth is called biodiversity or biological diversity. Biodiversity is a proportion of variety at the hereditary, species, and biological system level.

The diversity of the various kinds of organisms—the plants, animals, insects, and microorganisms that inhabit our planet—that can be found in the natural world around us is called biodiversity.

The majority of people recognize biodiversity by species, which is a group of distinct, interbreeding living organisms. Blue whales, white-tailed deer, white pine trees, sunflowers, and even microscopic bacteria.

Answer:

Guy on top is correct. It is 100%

Explanation:

As predicted by the Punnett square, 100% of the offspring have black fur for this cross.

When two individuals with the genotype BB (homozygous dominant for black fur color) are crossed, their Punnett square will look like:

 | B  | B  

--|----|----

B | BB | BB

--|----|----

B | BB | BB

All the offspring will have the genotype BB, which means they will be homozygous dominant for black fur color. Therefore, all the offspring will have black fur.

Answer:

This is because in biology, energy is transferred from organism to organism and some energy is lost along the way. Each energy transfer results in a loss of energy, so that energy is always at a lower level and can never be returned to its original high energy level. On the other hand, chemical elements can form products, then that reaction can be reversed and break back down into reactants. Additionally, the law of conservation of matter says that matter can't be created or destroyed, only transferred from one form to another.

Answer:

C

Explanation:

Answer: The correct option is D.

Genes are made of DNA and code for proteins.

Explanation:

This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.

DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.

Answer:

there is so much chlorophyll in the leaves we simply cannot see the other pigments. But as the daylight shortens, the tree does not make as much chlorophyll. As the chlorophyll starts to fade away, we are able to see the other colors (pigments) in the leaf, mostly yellow ones.

Explanation:

Answer:

Subtractive color mixing occurs when light is reflected off a surface or is filtered through a translucent object. For example, a red pigment or filter only appears red because it absorbs (subtracts) all of the light that is not red and only reflects or allows the red light. if you mix blue with red light, you get magenta light. When you mix (add) all the colors of light together, you get white light. This is why it is referred to as additive color. With subtractive color, you see color because some wavelengths are being reflected and others are being absorbed ( subtracted ).

Answer:

The first hill of a roller coaster is always the highest point of the roller coaster because friction and drag immediately begin robbing the car of energy. At the top of the first hill, a car's energy is almost entirely gravitational potential energy (because its velocity is zero or almost zero

Explanation:

Because friction and drag start depriving the car of energy right away, the first hill of a roller coaster is always the steepest part of the ride.

The resistance to motion created when two objects rub against one another is called friction. Friction occurs whenever two items come into contact with one another. Friction acts in the opposite direction from the motion and works against it. The two surfaces' respective materials have an impact on how much friction exists.

Static friction, sliding friction, rolling friction, and fluid friction are the four main categories of friction.

Friction and drag start depriving the car of energy right away. Therefore, the first hill of a roller coaster is always the tallest.
