Answer:
In natural asexual reproduction, roots can give rise to new plants, or plants can propagate using budding or cutting. In grafting, part of a plant is attached to the root system of another plant; the two unite to form a new plant containing the roots of one and the stem and leaf structure of the other.

Answer:
While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Brahe had collected a lifetime of astronomical observations, which, on his death, passed into Kepler’s hands. (Brahe, who had his own Earth-centered model of the Universe, withheld the bulk of his observations from Kepler at least in part because he did not want Kepler to use them to prove Copernican theory correct.) Using these observations, Kepler found that the orbits of the planets followed three laws.

What characteristic makes marine mammals different from other marine animals?
They all give birth on land.
They live only in the ocean and cannot leave the water.
They are carnivores that eat mainly fish.
They breathe air through lungs.
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.

______ An observer at Position B would see Star X as the brighter star
______ An observer at Position A would see Star X as the brighter star
Answer:
Yes
No

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 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.

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.

species if there is a change in the environment? *
Species A
Species B
Species C
Species D
ATID
Neither species B nor species D will survive because they compete for the same
resources
Species A has the best chance of survival because it has the most genetic diversity
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.

what measures to be taken in an operating room
Answer:
infection control- clean equipment to prevent spread of germs
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

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.

c.) crossing over
d.) synapsis
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.
