Explanation:

Answer: They are not regulated by contact inhibition.

Explanation:

Contact inhibition is a form of controlling cells. Cancer doesn't have contact inhibition, which is one of the reasons why it spirals out of place so easily.

Answer:

They are Not regulated by contact inhibition.

Explanation:

The other 3 options are not characteristics of a cancer cell. Cancer cells have unlimited cell division, no anchorage dependent inhibition, no contact inhibition, and forms tumors - hence they don't form a single layer of cells.

Answer:

deletion!

Explanation:

edge 2020

Deletion mutation is an example of frame-shift mutation.

Frame-shift mutation is a type of mutation in which the reading frame of a DNA (nucleotide) sequence is altered.

DNA or RNA is made up of nucleotides subunits, which is read in a particular pattern. When this reading pattern is shifted, frame-shift mutation is said to occur.

Deletion mutation and insertion mutation are the two kinds of mutation that results into frame-shift mutation.

Answer:

Light energy is harnessed in Photosystems I and II, both of which are present in the thylakoid membranes of chloroplasts. In light-independent reactions (the Calvin cycle), carbohydrate molecules are assembled from carbon dioxide using the chemical energy harvested during the light-dependent reactions.

Answer:

a) Humans depend upon other organisms for food and oxygen

Explanation:

Biodiversity refers to the richness in the species of organisms on Earth i.e the variety of biological organisms on the Earth. The importance of biodiversity cannot be overemphasized because of our dependence on the sustainability of biodiversity in our ecosystems.

The loss of biodiversity, which is becoming rampant by the day, is a major concern to us because we humans depend upon other organisms for food and oxygen. Humans are strictly heterotrophic and hence are reliant on variety of organisms for food. Plants also release oxygen gas via their photosynthetic process, which is key to our survival as a population.

The study of the environment is called ecology.

The correct answer is A.

The loss of animals and plants in the ecosystem is called loss of biodiversity. These reasons for the loss is as follows:-

The loss of these species has a high impact on the ecosystem as these have an important function to form forests.

All the species are dependent on each other.

Hence, the correct option is A that is humans depend upon other organisms for food and oxygen

Answer:

The correct answer is B make cells produce a functional CFTR protein.

Explanation:

Cystic fibrosis is a disease that is caused due to the mutation in the transmembrane protein known as cystic fibrosis trans membrane conductance regulator or CFTR. Cystic fibrosis trans membrane regulator proteins helps in the formation of thin mucus and due to the mutation in CFTR the mucus becomes thick.The disease cystic fibrosis basically affect the respiratory system.

If gene therapy is used to treat cystic fibrosis then it can replace the mutated CFTR gene with a functional one so that the cell containing CFTR gene can produce functional CFTR protein.

Answer:

A. gene therapies to fix the CFTR gene

C. inhalers to deliver CFTR to the cells

Answer:

Explanation:

Elements undergo chemical bonding-where electrons are shared, and rearranged to form various molecules and compounds. Bond formation in chemical reactions have specific requirements for molecular configurations and energy.

Molecules usually collide at random til conditions are favorable for bonding.  Chemical change or reactions occur at faster rates at higher temperatures. Heating molecules increases their collision frequency and makes it more possible for the correct molecular orientation (for breaking and forming bonds) and energy to react are present.

1.Both can change in light of new evidence

2.Both explain how a phenomenon works

Explanation:

Law and theory can be defined to be part of the nature of scientific knowledge. A scientific theory is a well-established explanation for observations of the natural world which can be verified by applying the scientific method, while a scientific law is a statement obtained from repeated experimental and/or observational procedures to describe and/or predict natural phenomena. Scientific theories can change when researchers discover new lines of evidence, while scientific laws also change based on new empirical evidence.
