A dichotomous key is a classification tool used to identify organisms based on morphological or behavioral characteristics. Individual C is a Roundus tricurlus.

A dichotomous key is a significantly useful tool to classify organisms.

If you have an organism -or part of it- and you need to taxonomically identify it, you use a dichotomous key.

The key provides an easy and fast way for identification by describing different morphological or behavioral traits, leading you to the correct taxonomic classification.

The term dichotomous refers to how information is provided.

You will always have two options per feature (a and b, or 1 and 2), and you will have to choose one of them according to the characteristics of your organism.

Once you choose one of the options according to your organism, the key leads you to the following description, and you will have to choose one of the options again.

You will repeat this until you reach the name of your organism.

The key describes only specific traits that are useful for differentiation.

In the exposed example, for instance, we need to know the name of the individual C.

The first description is about the head size. The key asks you if the individual has a small or a large head. It has a small head, so the key tells you to move to description 2.

1a. Has a small head--------------------------- go to 2

1b. Has a large head--------------------------- go to 3

The second description is about the body shape. The key asks you if your organism has a narrow or a rounded body. And this individual has a rounded body, so the key tells you to move to description 7.

2a. Has a narrow body ------------------------ go to 6

2b. Has a round body -------------------------- go to 7

The seventh description is about antennae. Does your individual have curly or straight antennae? It has curly antennae. You have reached your organism's name. It is a Roundus tricurlus.

7a. Has a curly anteanne ------------------------ Roundus tricurlus

7b. Has a straight antennae--------------------- go to 8

Individual C is a Roundus tricurlus.

And at last it comes to decomposer which are micro organism that absorb the wastes in the soil and make the soil fertile.

Thus, herbivores comes under Primary consumer.

Three out of four of their offspring will be white when Two rabbits mate, each with one dominant gene (f) for black and one recessive gene (f) for white. Thus, the correct option is B.

A trait is represented by two contrasting factors of a gene in a heterozygous individual, while the homozygous individual has two copies of the identical factors, according to the law of dominance. As a result, the heterozygous rabbit's genotype will be Bb, whereas the homozygous recessive rabbit's genotype will be bb.

phoresy - a commensalistic relationship in which one organism is transported by another.

monogamy - having one mate for a whole life span

mutualism - a symbiotic relationship between two organisms in which

both species receive some type of benefit

polyandry - when females mate with multiple males

polygyny - when males mate with multiple females

parasitism - a relationship between two or more organisms of different

species in which one benefits and the other is harmed

Symbiosis is the name given to any close and long-term interaction between two different species.

This interaction can be beneficial to one part only and harmful to the other (parasitism), it can be beneficial to all parts (mutualism), or it can benefit one part without influencing neither positively nor negatively the other (commensalism).

A mating system refers to how a group is organized in terms of sexual behavior. When it comes to animals, the phrase refers to which males and females mate when certain conditions are met. Monogamy, polygamy (including polygyny, polyandry, and polygynandry), and promiscuity are all recognized systems that lead to various mate choice outcomes and so influence how sexual selection operates in the species that practice them.

784109 People per sq. mi land would its people need if the population density is 3,826 people/km2.

The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.

The population density equation below can be used to calculate the population density of a piece of land:

        Population Density = Population/ Area

The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.

It's therefore an effective way of producing new individuals from rare and endangered plants, helping to preserve the species.

Gametes are the structure required for fertilization and are formed from germ cells through meiosis. Gametes produced by an organism contain a combination of genes from that organism which is different in every individual due to independent assortment.

When the alleles of two different genes get sorted into gametes independently of one another is referred to as independent assortment.

In other words, different alleles and genes are independently transferred to offspring during the meiosis in reproduction through the fusion of gametes.

Thus, it can be concluded that gametes produced by an organism contain a combination of genes from that organism which is different in every individual due to independent assortment.

Answer:

B, It changes from 379 J to 243 J.

Explanation:

"It changes from 379 J to 243 J" best describes the potential energy of this system.

Total energy in a system can be divided into two main components: kinetic energy and potential energy. The given information states that the kinetic energy of the system changes from 296 J to 432 J. However, no direct information is provided about the change in potential energy.

Since the total energy in the system remains constant at 675 J, any change in kinetic energy must be compensated by an equal and opposite change in potential energy to maintain the overall energy balance.

If the kinetic energy increases from 296 J to 432 J, the potential energy must decrease to maintain a total energy of 675 J. Therefore, the potential energy changes from a higher value of 379 J (initial potential energy) to a lower value of 243 J (final potential energy). This change in potential energy is consistent with the increase in kinetic energy from 296 J to 432 J, ensuring the conservation of total energy in the system.

Explanation:

One or two purple alleles in flowering pea plants will result in purple blooms.  so there will be 50 percent ratio. This is because one purple gene causes enough pigment to be synthesized to produce all purple flowers.

A dominant allele is a variant of a gene that causes a specific trait even when other alleles are present. A functional protein is usually encoded by a dominant allele. Because one copy of the allele produces enough enzyme to furnish a cell with plenty of a given product, it is dominant.

As a result, the purple allele has a dominant role, while the white allele has a recessive role.

0.0085420560747664 Seconds

Explanation:

0.914 ÷ 107 = 0.0085420560747664

The time that the nerve will take for a nerve impulse to travel the full distance of this nerve is 0.00854 seconds.

Sciatica is caused by a pinched sciatic nerve. The most common cause is a herniated disc in the spine or an overgrowth of bone, known as bone spurs, on the spinal bones.

A tumor can occasionally impose pressure on a nerve. A condition, such as diabetes, can also harm the nerve. The speed of something is how fast the object is moving. It is calculated by the distance divivded by time.

Given, the length of the sciatic nerve is 0.914 m

The speed of an action potential is 107 m/s.

The length is divided by the speed

0.914 / 107 = 0.00854 sec.

Therefore, the full distance of this nerve is 0.00854 seconds.
