Answers

Answer 1

Answer:

Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. ... The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site.

When a honey bee stings or a pathogen attacks, the body elicits an inflammatory response. Label the processes that happen during an
inflammatory response.

Answers

The inflammatory response is a type of body response produced in response to damaged tissue, attack of pathogen and or any other cause.

The body shows an inflammatory response in the following manner:

1. Recognition of stimulus- receptors recognize the antigens.

2. Release of inflammatory markers: affected cells produce chemicals like histamine, bradykinin, and prostaglandins.

3. Vascular permeability changes and leukocyte (WBC) recruitment- released chemicals causes the blood vessels to leak fluid causing swelling and attract WBC.

4. Accumulation of leukocytes- WBC performs the process of phagocytosis which eats dead or damaged cells and germs.

Which of the following is true about subatomic particles?
The mass of a neutron is equal to the mass of a proton


Neutrons have no charge and are the lightest subatomic particle


Electrons are negatively charged and are the heaviest subatomic particle


Protons are positively charged and the lightest subatomic particle

Answers

Answer:

Neutrons have no charge and are the lightest subatomic particle

Explanation:

Nucleus of an atom contains three subatomic particles. These are protons, neutrons and electrons.

Mass of a proton is  [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.

Mass of a neutron is  [tex]1.67[/tex]×[tex]10^{-27}[/tex]kg.

Mass of an electron is [tex]9.1[/tex]×[tex]10^{-31}[/tex] kg.

Also, protons are positively charged, neutrons have no charge and electrons are negatively charged.

Therefore, we can conclude that the mass of a neutron nearly equals the mass of a proton.

ICM.06] Scientific research shows that our global climate is changing as a result of an increase in greenhouse gases. Arctic sea ice is decreasing in both surface area and thickness. Which of the following statements best describes the
consequence of decreasing Arctic sea ice?
The melting of sea ice will decrease the effects of global warming in the area as the ice absorbs heat
O seawater levels wil decrease making t difficult for marine animals to survive.
Animals that rely on the sea le for survival may become extinct as their habitat disappears.
The milder temperatures will allow for greater survival rates for native species

Answers

As a result of decreasing Arctic sea ice, animals that rely on the sea level for survival may become extinct as their habitat disappears.

The increase in the atmospheric greenhouse gases means that more radiant energy from the sun that could have escaped back into space is being absorbed, leading to an increase in the global temperature.

The increase in the global temperature means that more Arctic sea ice would be melting and decreasing in size. As the ice melts, the water moves into seas thereby causing a rise in their levels.

A rise in sea level means the disappearance of coastal habitats. Thus, a loss in biodiversity will occur as the habitats of plants and animals disappear as a result of the rise in sea levels.

A particular type of potato can only be produced by cloning from it's eyes or budding. Large commercial growers worldwide now plant only this particular type. Some scientists are warning that exclusively growing this type of potato by asexual reproduction presents a serious disadvantage. Why are these scientists concerned?​

Answers

If an economically important crop such as the potato as highlighted in the illustration can only be produced by cloning, it is normal for scientists to be concerned because a single even of disease attack might end up wiping the entire crop away.

Cloning is more or less mitosis - a division of vegetative cells. In other words, there is no form of genetic recombination in clones. All clones have exactly the same genes as themselves and their parents.

The implication of an entire population of an organism having the same genetic composition is that they will be resistant and susceptible to the same limiting factors - be it biotic or abiotic. Just an event of a disease outbreak might end up wiping all the population away because there will not be any resilience.

Answers

Answer:

The answer to this question is B.) asexual reproduction

Explanation:

Hope this helps :) !!!!!!!!!!!!!!!!!

In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.

What is asexual reproduction?

Asexual reproduction is defined as the mode of reproduction in which only single parent is involved and in asexual reproduction fewer offspring are produced. There are several types of asexual reproduction and these are binary fission, spore formation, vegetative reproduction, and fragmentation.

Reproduction has been defined as the process that has been carried out by the living organisms and during the process of the reproduction the living organisms produces their own young ones and feed them. Reproduction has the supreme quality of the living things.

There has been two types of the reproduction and these are the sexual as well as asexual reproduction. The process of the reproduction in which two parents has been involved has said to be sexual mode of reproduction and the process of the reproduction in which only single parent has been involved in known as asexual mode of reproduction. The example of asexual reproduction are budding, fragmentation, spore formation, and binary fission.

Therefore, In asexual reproduction fewer offspring are produced. Asexual type of reproduction is the type of reproduction in which single parent is involved. Thus, option B is correct.

Grooves created from glacier movement travel in opposite directions on each continent.

Answers

The characteristics of the tectonic plates allows to find the result for the correct statement is:

Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.

The tectonic plate model establishes that by the hot magma convection currents the solid crust breaks in the weakest areas, forming plates that move floating on this,  hot magna that can rise through the cracks and separate these plates.

In the attached we see a diagram of the magnetic alignments in the rocks from a tectonic plate, we can see that the alignment changes due to the inversion of the earth's magnetic field in such a way that we can appreciate the separation of the two plates.

Another proof is that other similar animals are on continents separated by great distances.

Let's analyze the different claims:

a. False. Radioactive dating evidence gives that the rocks give that the rocks on the two continents are the same age.

b. False. Fossils of the same spice are found on several continents.

c. True. These rocks when they emerged were aligned and when moving and the magnetic field reversed the rocks are no longer aligned, this is one of the greatest proof of the separation of tectonic plates.

d. False. The furrows of the glaciers go from the North to the South, it does not have the direction of the displacement of the plates.

In consequence of the characteristics of the tectonic plates we can find the result for the correct statement is:

Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.

In the cells of humans and other animals, a great deal of energy is dedicated to operating a pump that transports sodium (Na+) ions out of cells and potassium (K+) ions into cells. This transport creates a chemical and electrical gradient. Maintaining the proper balance of sodium and potassium is critical to ensuring that nerve cells work properly. Nerve cells drive muscle contractions—including heart muscles—and are responsible for animals’ abilities to sense their environment and for humans’ ability to think.

Scientists gain a better understanding of the sodium-potassium pump by creating models of what the pump accomplishes. Such models are used to examine many other complex processes as well.

This model of the sodium-potassium pump illustrates the process by which sodium is pumped out of cells and potassium is pumped in. The sodium-potassium pump moves the two different ions in opposite directions.
