True or False: When a biotic factor dies, the molecules within that
organism enter into the nutrient cycle.
Answer:
Explanation:
True
When a biotic factor dies, the molecules within that organism enter into the nutrient cycle is a true statement.
Biotic factors:
There are two factors in a living system. Biotic and abiotic. all living organisms are biotic components. Plants, animals, and other living components are biotic components. Air, water, and sunlight are abiotic components.
Biotic and abiotic components together make the nutrient cycle. When biotic components die their molecules enter the nutrient cycle. Microorganisms act on the biotic component when they die.
They release carbon, hydrogen, and other molecules into the atmosphere when they die.
Therefore, When a biotic factor dies, the molecules within that organism enter into the nutrient cycle is a true statement.

Answer:
d
Explanation:
bc its d
The characteristic that makes marine mammals different from other marine animals is that they breathe air through their lungs. Thus, the correct option for this question is D.
What are the characteristics of marine mammals?The characteristics of marine mammals may significantly include they breathe air through the lungs, being warm-blooded, having hair (at some point during life), and producing milk to nurse their young — while also living most or all of their lives in or very near the ocean.
Marine mammals have the same characteristics as all other mammals, but they have adapted to living all or part of their life in the ocean. Many have streamlined bodies to help them swim faster. With similar to the Fishes and other animals that have gills so they can breathe underwater. Marine mammals do not have gills. They have to come to the surface to breathe.
Therefore, the characteristic that makes marine mammals different from other marine animals is that they breathe air through their lungs. Thus, the correct option for this question is D.

A baker activates yeast cells with hot water, and adds sugar as their source of food. As the yeast begin their metabolic processes, the bowl it is in is covered with plastic so that no oxygen can get to them. At this point, the yeast will __ *
1 point
a. produce far more ATP than is necessary in response to the lack of oxygen
b. continue to go through aerobic respiration if enough sugar is present
c. die since all living organisms need oxygen to survive.
d. perform anaerobic respiration in the absence of oxygen
Answer:
The correct answer would be - option D. perform anaerobic respiration in the absence of oxygen.
Explanation:
Yeast is a facultative anaerobic single-cell organism that can live without oxygen. If yeast cells did not get the oxygen they use anaerobic respiration to get the energy.
If the baker activates these cells and stops them to get oxygen the yeast cells have to switch to anaerobic respiration to survive and produces ethanol and releases carbon dioxide.
What do all vectors and scalars have?
A. velocity
B. orientation
C. direction
D. magnitude
Answer:
D. magnitude
Explanation:
Scalars are quantities that are fully described by their magnitude (size) only. For example, a temperature is fully described by saying "80 degrees Celsius." We do not need to include a direction.
A vector contains both magnitude and direction. Acceleration is fully described by including both speed and direction: "45 m/s, North."
Both scalars and vectors have magnitude.

Answer:
b.) nondisjunction......
A woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.
What do you mean by Chromosomes?Chromosomes may be defined as tiny, threadlike structures inside most cells of every organism, or living thing which carries the genetic information.
The presence of 3 X chromosomes indicates the condition of trisomy which arises as a result of non-disjunction.
When homologous chromosomes fail to separate at meiosis resulting in a germ cell containing 24 chromosomes rather than 23.
Therefore, a woman is found to have 47 chromosomes, including 3 X chromosomes. This condition likely resulted from nondisjunction during meiosis.

All items needed for the operation should be in place and an adequate supply of regularly used items should be on hand to minimise movement to and from theatre during the operation
Everything needs to be sterile
All instruments need to be inspected for any signs of contamination after the sterilisation process
Shoes from outside should never be worn inside an operating room
Theatre hats are worn routinely, and prevent loose hair and skin from falling on wounds or equipment
The surgical mask was introduced over a century ago. Its continued use is controversial as evidence is not conclusive that wearing a mask reduces postoperative infection. Wearing a mask, however, does protect the practitioner from contact with body fluids

Answer:
DNA is a self replicated material that is inside almost every living animal, and human being. DNA contains genetic codes. Dna holds genes, for example those who created you, there genes are passed on to you causing it to also be in ur DNA. It contains instructions that an organism needs to live, develope and reproduce. DNA serves as the primary unit of heredity in different types of organisms. (It might not be long enough but maybe this could atleast be used as half a paragraph)

What is the effect of an increased concentration of calcium ion in the sarcoplasm?
Answer:
When calcium concentration increases during depolarization, it shifts the conformation of troponin and tropomyosin, and actin is able to associate with myosin. As calcium is taken up again by the sarcoplasmic reticulum the muscle cell relaxes.
The effect that can be associated with increase in concentration of calcium ion in the sarcoplasm is :
Changing of shape and position of tropomyosin.
Can also cause muscles stiffness.
When the Ca2+ concentration become high in the sarcoplasm, there would be change in the position of tropomyosin as result of the binding effect of Ca2+ binds on troponin.Then the tropomyosin will be moved away from myosin binding sites on actin, then a cross bridge will be formedHowever, the effect if this on muscles is muscles stiffness.

Write a set of directions for a red blood cell to deliver oxygen to the brain. Lungs heart-brain aorta arteries veins
Answer: How does oxygen get into the bloodstream? Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.OK Our typical red cell passes from the capillary into the venules, and then into veins. It flows back to the right side of the heart, completing the second loop of its circuit [music out]. As we saw, it then travels back to the lungs.The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Hillsdale and Cordera are the same distance from the equator, and both are near the ocean. Is Cordera warmer, colder, or the same temperature as Hillsdale? Explain why as completely as you can.
Answer:
it is expected that Hillsdale and Cordera have nearly similar temperatures.
Explanation:
In the first place, it is important to note that there is an inverse relationship between latitude and temperature: temperatures are typically warmer near the Equator (lower latitudes) and cooler near the poles (higher latitudes). This phenomenon is due to the fact that the angle of solar radiation is smaller at higher latitudes, and thereby less solar radiation is received/absorbed near the poles than at the Equator. Moreover, another important factor that also determines the temperature is altitude: at higher altitudes, the temperature is lower. This phenomenon is due to the fact that at higher altitude air molecules spread out further, and therefore the temperature decreases. In consequence, at the sea level, the temperature is higher than at higher altitudes.

Species C has the best chance of survival because it has no gene mutations
None of the species will survive because bacteria reproduce asexually
Answer:
A bcoz it change the environment
Species A has the best chance of survival because it has the most genetic diversity.
What is genetic diversity?Genetic diversity is defined as the set of different inherited traits that occurs within a species. Those organisms having higher genetic diversity have more chances of survival.
So we can conclude that Species A has the best chance of survival because it has the most genetic diversity.
