PLEASE HELPPP What type of signaling is represented in the figure?

Answer: I think these are the answers:

- Cancer can spread around the body.

- Cancer cells invade healthy tissue.

- Cancer cells display contact inhibition.

- Cancer comes in many forms.

- Cancer cells divide uncontrollably.

and I think "Cancer does not obey contact inhibition." is one too... I hope this helps! :D

Explanation:

Cancer cells:

• Divide uncontrollably

• Comes in many forms

• Invade healthy tissues

• Does not obey contact inhibition

Cancer is a diseased condition in which uncontrolled cell division takes place.

Cancer are of two main types: benign and malignant.

Benign tumours are localized to a particular organ and thus can be removed through chemotherapy or surgery.

Malignant tumours spread to body parts through blood stream and attack the healthy cells. This property of metastasis is unique to cancer cells.

Normal cells show their contact with the adjacent cells. In cancer, contact inhibition is lost and so they divide in an uncontrolled manner.

Breast cancer, leukaemia, lung cancer etc are some of the examples of cancer.

Cancer is detected through tissue biopsy. X-Rays, CT-Scan, MRI are some other techniques that detect cancer in the body.

Cancer can be treated if diagnosed early. Radiotherapy, chemotherapy and surgical intervention are the part of cancer treatment.

Therefore, cancer is considered a serious medical complication.

RESOURCE LIBRARY COLLECTION

DISTRIBUTION OF NATURAL RESOURCES

Different regions have access to different renewable or nonrenewable natural resources such as freshwater, fossil fuels, fertile soil, or timber based on their geographic location and past geologic processes. Access, or the lack thereof, contributes to a place’s economic development, political relationships, and culture. For example, the Great Plains region of the United States is known for its abundance of fertile soil. As a result, its main industry is agriculture. Corn, soybeans, and wheat are globally exported from this region and serve as the main economy. On the other side of the spectrum, the desert southwestern region of the United States depends on the Central Arizona Project canals to transport water from the Colorado River in order to support agriculture and urban areas. Arizona’s right to use water from this river stems from the Colorado Compact, an agreement established in 1922.

Answer:

Introduction of Non-native species would be the answer. ( B )

Explanation:

Now let's break it down.

A. Competition due to overpopulation

Competition due to overpopulation, as competition of resources rises, species will fight among each other, and slowly, population will go down. But I don't see the reason of why it would cause an extinction... perhaps a decrease of population. See, once populations starts decreasing, resources will increase. And ONCE resources increase, populations starts increasing, and there goes competition. Resources decreases, populations decreases, and the whole process repeats. So I'm not quite sure whether it will cause extinction of a species.

B. Introduction of Non- native species.

So what does it mean by Non-native species?

It means that species that have no effect and doesn't exist in the ecosystem. So that will definitely not affect the population whatsoever.

C. Catastrophic Events

Well, common sense. Many people died of tsunamis, tornado and other natural disasters every year. Too many disasters can cause the population to cease.

D. Disease

This we can relate, especially the Coronavirus. Many humans died of the deadly virus. Same goes to animals. If a disease gets too deadly, population will decrease and drive the species to extinction.

So, the Answer would be B.

Among the given options, the one that is a natural cause of extinction would be:

b). Introduction of non-native species.

'Non-native species' are described as the species that are introduced to an ecosystem different from its native habitat.

These species are severe threat to the existing ecosystem of the new habitat including plants, animals, aquatic life, etc. where they've been shifted.

Thus, it is not a natural cause as these species are not naturally introduced but the humans introduce them.

They turn so dominating to get their food and other things that it lead not only harmful but also lead to the extinction of the native species.

Hence, option b is the correct answer.

The disadvantages of an agricultural society include dependence on a few crops, greater vulnerability to natural events and need for intense physical labor. The economy of an agricultural society depends on climatic factors.

An agricultural society can be defined as a population where the economy is based on producing extensive crops.

An agricultural society can also be defined when a country is based its economy on agriculture instead of industrialization.

These economies are highly dependent on climatic natural factors which can affect the yield of a limited number of crops (e.g., maize, wheat, soybean, etc).

A.Petals. Usually, petals are the most prominent part of a flower structure, owing to their vivid color (in most flower examples) and sometimes scent. Their main function is to attract pollinators and also protect the inner reproductive structures of a flower. In some flowers, petals are absent or reduced.

B.Stamen: The pollen producing part of a flower, usually with a slender filament supporting the anther. Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower. The ovary often supports a long style, topped by a stigma.

C.Pistil interaction precedes fertilization in the flower. Important changes occur in the pistil, which play a role supporting, but also controlling pollen-tube growth

D. The ovule is the organ that forms the seeds of flowering plants. It is borne in the ovary of the flower and consists of nucellus protected by integuments, precursors of embryo/endosperm, and seed coat, respectively.

Cellular development, replication, and cell repair are controlled by genetic information stored within DNA molecules. The long-chain, helical macromolecules of these deoxyribonucleic acids, are constructed from complex sequences of covalently bonded monomers called nucleotides.  

Genes, can span several nucleotides and even multiple chromosomes. They are encoded through the processes of transcription, translation to become proteins, that determine physical characteristics or phenotypes.

Answer:Vacuole

Explanation:Vacuoles basically do the functions of storage, ingestion, digestion, etc.

Answer:

The organism would not be able to make more than one type of protein.

Explanation:

All amino acids have a standard structure with variation in the R group. They have an amide functional group on one side, and a carboxyl functional group on the other side of the molecule.

The reason we have such diverse types of proteins in our cells is because there are different R groups across the twenty amino acids found in nature. These R groups contain additional elements and form different structures and functions, based on their properties.

If all R groups were the same, then all amino acids would be the same. This would result in only one type of protein, as all proteins are made of chains of amino acids.

Answer:

The lens is located in the eye. By changing its shape, the lens changes the focal distance of the eye. In other words, it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned at various distances.

Explanation:

Also, I searched this up, but I hope this helps :) !

The main optical function of the lens is to transmit light, focusing it on the retina. The cornea contributes about 80% of total refraction, while the lens fine-tunes the focusing of light onto the retina.

Refraction is the redirection of a wave as it passes from one medium to another. The redirection can be caused by the wave's change in speed or by a change in the medium.

Moreover, refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. This bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. Even our eyes depend upon this bending of light.

Therefore, light waves change speed when they pass across the boundary between two substances with a different density , such as air and glass. This causes them to change direction, an effect called refraction.

Answer:

What would explain the change in reaction rate —degradation of cellulose by the enzyme cellulase—after 75 minutes is the depletion of the substrate on which the enzyme must act.

Explanation:

A chemical enzymatic reaction, such as cellulase degradation of cellulose, occurs until the substrate is consumed.

The solution to which cellulase is added has the same concentration of cellulose, and what is done is to add enzyme. In the graph you can see that the reaction takes place over time, decreasing the amount of glucose obtained. From 75 minutes onwards the reaction rate decreases as well as the amount of glucose obtained from the reaction, which is due to the fact that the substrate —cellulose— is being depleted.
