responds to tissue damage pain
Answer:
Upon tissue injury, damaged cells release inflammatory chemical signals that evoke local vasodilation, the widening of the blood vessels. Increased blood flow results in apparent redness and heat. In response to injury, mast cells present in tissue degranulate, releasing the potent vasodilator histamine.

What occurs in the light independent reactions?
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.

Which value is a good estimate of the railroad’s average elevation?
Which option describes a similarity between scientific laws and scientific theories? 1.Both can change in light of new evidence. 2.Both explain how a phenomenon works. 3.Both are purely observations of nature. 4.Both are suggested explanations that are starting points.
Answer:
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.
Why is the world's loss of biodiversity a source of concern?
O a. Humans depend upon other organisms for food and oxygen
b. Species have value to humans, both monetary and because we like them
c. Tourism depends on the preservation of certain animal species
d. Both (a) and (b)
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:-
Overexploitation.Invasion of alien speciesGreedHabitat lossThe 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

Which is a frameshift mutation? substitution nonsense silent deletion
Answer:
deletion!
Explanation:
edge 2020
Deletion mutation is an example of frame-shift mutation.
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.

How would the seasonal paths of the Sun change for a location that is more North of this latitude?
Answer:
At the North Pole, the sun is above the horizon for six straight months (March through September), spinning around in horizontal circles, reaching a maximum height of 23.5° above the horizon at the June solstice. As you travel southward in the northern hemisphere, the noon sun gets higher and higher.
Explanation:
Add the north pole the sun is above the horizontal for six straight months

Extreme acidity in soil helps plants thrive because the hydrogen ions kill off all harmful microorganisms that may stunt a plant's
development
True
False
Answer:
False
Explanation:
The best pH for soil is around 7-8 and the plant needs some of the microbial organisms to grow.
Answer: The correct answer is False
Explanation: This has been confirmed correct.
While some acidity is helpful, high acidity damages the root systems of plants.
What kind of new therapies are scientists working on to treat cystic fibrosis?
Select all that apply.
gene therapies to fix the CFTR gene
injections to add water directly to the mucus
inhalers to deliver CFTR to the cells
gene editing to remove the CFTR protein
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
Which statement best describes cancer cells?
They grow as a single layer of cells.
They cease to reproduce after 20–50 mitotic divisions.
They reproduce only when needed to replace missing cells.
They are not regulated by contact inhibition.
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:
If you place a sprouted onion with the roots down in a glass of water, it will continue to grow on the top with new shoots. You can either cut off the top part and use it in recipes, or plant the whole onion, roots and all, in soil and watch it grow. All types of onions will regrow.
During a chemical reaction, increasing the temperature often
OA increases the rate of chemical change.
ОВ.
decreases the rate of chemical change
OC.
reverses the direction of chemical change.
OD. prevents a chemical change from occurring.
Answer:
A increases the rate of chemical change.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.
