First, there is a need to understand what the carrying capacity is as it relates to the environment:
Carrying capacity refers to the maximum number of individuals of a particular species that and environment can support based on the resources it has. The population of a species in an environment grows and oscillates around the carrying capacity of the environment.Now let us look at the graph. The population size grew from 0 and then leveled off at 2,000 with time. The leveling-off also happened without any oscillation, meaning that the maximum population size the environment can support is 2,000.
Hence, the portion on the graph that indicates the carrying capacity would be the plot where the population size is 2,000 and the time being between 12 and 18. This has been circled and labeled as 'K' in the attached image.

do fertilised eggs divide to form a foetus
Answer:
yes
Explanation:
the chromosome number of the egg and and sperm are halved ,and are then joined together. the fusion of the the nucleus of the haploid male gamete with the haploid female gamete is referred to as fertization and the product of fertilization is zygote.
The diploid single zygote then divides repeatedly and develops to produce the offspring whose somatic cells are diploid.The zygote is the initial stage in baby development. It is also known as a fertilized ovum formed from the union of the sperm cell and the egg cell. Foetus refers to the final stage in baby development.

Which of the following describes a cnidarian with a polyp body form?
a tube-like body attached to a firm surface with tentacles on the opposite side of the attachment, surrounding the animal's mouth
an animal with a body lacking tissue
a body shaped like an umbrella that is capable of swimming and has tentacles hanging below it
an animal body that digests food intracellularly rather than extracellularly within a gastrovascular cavity
Answer:
a tube-like body attached to a firm surface with tentacles on the opposite side of the attachment, surrounding the animal's mouth
Explanation:
A polyp is a type of body structure that a cnidarian can assume. The cnidarians, in turn, are invetebrate animals of aquatic life. This group of animals includes jellyfish, corals and sea anemones.
In polyp form, cnidarians are not actively moving, although some do move when they feel threatened. This is because they appear as a tubular structure, with one end fixed to the sea floor. The other end presents the animal's mouth, which is surrounded by tentacles that are responsible for capturing the prey needed for food.

a tube-like body attached to a firm surface with tentacles on the opposite side of the attachment, surrounding the animal's mouth

When trees are uprooted and the land left bare what happens to the rain water?
Explanation:
when trees are cut down, the bare surfaces left behind absorb more heat than the forest they replaced.And that heat helps draw air upward, pulling moist air in from nearby forested land that increases rainfall in the immediate area.
Amphibians are not completely free to live on dry land because they can escape from predators by jumping into the water. their food organisms live in water. they obtain oxygen from water through gills. their reproduction depends on water. their ancestors were fish.
Answer:
they obtain oxygen from water through gills
Explanation:
Amphibians are a group of organisms renowned for their ability to live on land and water. They include frogs, toads etc. Despite their numerous adaptive features that enable them to survive on land, they can still not live independently of water or aquatic environment.
This is because a stage of the life cycle of most amphibians require water for respiration via their GILLS. Amphibians in their juvenile stage e.g. tadpoles rely on water for them to breathe. Adult amphibians make use of lungs and skin for respiration.

Overproduction arrow pointing Struggle for survival arrow pointing Survival of the fittest arrow pointing Changes in traits of species
Dynamic equilibrium
Genetic manipulation
Material cycles
Natural selection
Answer:
Natrual selection
Explanation:
your welcome girlies <333
The concept illustrated in the flowchart is Natural selection. The correct option is 4.
What is natural selection?Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.
Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.
Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.
Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.
These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.
Thus, the correct option is 4.

Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier. Group of answer choices
Complete question:
Frequently, a group of related species will each have a unique courtship ritual that must be performed correctly for both partners to be willing to mate. Such a ritual constitutes a ________ ________ reproductive barrier.
Group of answer choices
A) behavioral . . . prezygotic
B) mechanical . . . postzygotic
C) temporal . . . prezygotic
D) gametic . . . postzygotic
Answer:
A) behavioral . . . prezygotic
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
There are different types of reproductive barriers.
Pre-copulatory o pre-ziygotic:
Ecological or by habitat isolation; Seasonal or temporal; Sexual o ethologic; Mechanic; Gametes incompatibility.Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.Behavioral isolation is also known as ethological isolation or sexual isolation. This is a prezygotic barrier that refers to the fact that even when many species occupy the same area, they are not sexually attracted to each other, and might be rejected because of behavioral factors, not getting to mate. This mechanism includes courtship patterns or mating rituals and specific chemical signals that allow recognition between individuals of the same species.

One moth population carries three alleles at a genetic locus: X1, X2and X3. X1is dominant to X2and X3; X1produces red antennae. X2is co-dominant to X3; X2X2produces yellow antennae, X3X3produces white antennae, and X2X3produces light yellow antennae. The phenotypes in a population are as follows: 0.04 white; 0.16 light yellow; 0.16 yellow; 0.64 red.Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the X3allele in this population
Answer:
The correct answer is - 0.20
Explanation:
According to Hardy Weinberg equation under specific conditions the frequencies of the allele in the gene in a given population remain constant. Thus according to this frequencies of allele and genotype will remain the same through the generation unless there will be no evolutionary influence.
It helps us to predict the genotype frequencies in a large population. If there are two alleles having allelic frequencies p and q and we know equation of probability and frequencies add to 1
p2+2pq+q2=1
The X3X3 genome produces white antennae. Now Phenotypic frequency of the white antennae is 0.16 or 0.04 in the whole population. Hence the frequency of X3 should be a square root of 0.04 i.e, 0.20.
