Answer:
Option (a), (c) and (d).
Explanation:
The prokaryotes lacks the nucleus and the membrane bound organelles. Eukaryotes have well defined nucleus and the endomembrane system is present in eukaryotes.
The main site of the oxidative phosphorylation is the mitochondria in case of eukaryotes. The mitochondria are known as semi autonomous organelle as it contains its genetic material. As the oxidative phosphorylation occurs in mitochondria, this is the main site of ATP production. The mitochondria is a membrane bound organelle and absent in case of prokaryotes.
Thus, the correct answer is option (a), (c) and (d).
Answer:
The correct answer are
a. Are the sites of oxidative phosphorylation.
c. Possess their own DNA and
d. Are sites of ATP production.
Explanation:
Mitochondria are double membranous structures that are found in eukaryotes. These are structure present in almost all the eukaryotes. The process of aerobic respiration takes place in mitochondria.
Mitochondria have their own DNA which is smaller than nuclear DNA and are circular in shape like bacterial DNA.It is called the powerhouse of the cell because ATP synthesis takes place in mitochondria which provide energy to the cell.
The ATP is produced through the process of oxidative phosphorylation which occurs in the matrix and mitochondrial membrane. In oxidative phosphorylation, ATP is produced by energy released from the oxidation of NADH and FADH₂ molecules.
Therefore the correct answer is a,c, and d.
Answer:
2 out of every 5 or 2/5
Explanation:
there are 200 black cats because there are 300 calico there are 500 total so it would be 200/500 or 2/5

Explaining Below V
Explanation:
There are 5 different kinds of climates globally.
Tropical
Dry
Temperate
Continental
Polar
Tropical climates are very hot and humid. There's lots of rain (estimated around 59-60 inches per year). The average temperature tends to be over 60°F or 18°C. Plants you can find are incredibly diverse in both plants and animals. You can find animals such as monkeys, parrots, anacondas, jaguars, tigers, and many more. The tropics have the greatest plant diversity on the planet. The climate generally is centered around the equator.
Dry climates are generally very warm and dry. Humidity is very unlikely as everything is mostly dry heat. There's very little precipitation. Dry climates usually consist of deserts (Fe: Sahara desert). Plants such as cacti, succulents, wildflowers, and small trees, shrubs, and grasses. Animals can vary from things such as tarantulas, rattlesnakes, foxes (only some), camels, and rabbits. Depending on the desert, the heat can shoot up past 100°F while being frigid at night.
Temperate climates are generally warm summers with storms and mild winters. Plants can range from owls, raccoons, sparrows, meadowlarks, deer, and occasionally bears. This climate fluctuates the most in temperature compared to other climates. Plants can range from things like clover plants to a common bean.
Continental climates have mediocre summers with very cold winters. In the winter, snowstorms and strong winds are most likely. Sometimes, the temperature can drop below -22°F. Plants can range from Lavender and fern to Carolina Lupine and Silver maples. Animals can consist of squirrels, chipmunks, prairie dogs, skunks, and raccoons.
Polar climates are frigid. Its cold year round. There's animals such as polar bears, foxes, wolves, and caribou. Plants can vary from Tundra moss to Arctic Willow. Plants are generally smaller and are more like tiny shrubs.
Hope this helps.
Answer:
If this was edmentum. this was my question and answer
Explanation:
see pic below
Answer:
Ok, no boxes but whatever
Mammals - Endothermic Homeostasis (Warm Blooded), Hairy Body, Have babies live
Birds - Endothermic Homeostasis(Warm Blooded), Have eggs, feathers, claws
Bacteria - Single celled, use binary fission to divide
Fungi - Multi or single celled, have chitin cellular walls
Plants - Have cellulose plant walls, multicellular organism
Archae Bacteria - Same as normal, except they live in crazy enviorments, like at the bottom of the ocean or in a volcano or radiation pool
Protozoa - Single celled organism class, like ameoba
What is the cause of his symptoms. Explain the mechanism.
Answer:
The lower back pain and bilateral leg pain is due to over and intense physical activity which causes stretching of ligaments and muscles resulting in back and leg pain. Such pain can be managed by limited or by reducing physical activity. The dark color of urine is due to the presence of bile (bilirubin) in the urine. Here the patient has a past medical history of alcohol abuse. Excessive alcohol intake enhances gut permeability resulting in enhanced absorption of bacterial endotoxins. Excessive endotoxins in the liver cause damage of the kupffer cells in the liver, resulting in the release of bilirubin in the blood which ultimately passes through kidneys into the urine.
Explanation:
Answer:
denaturing of the peptide bonds
Explanation:
Enzymes are proteins that help speed up chemical reactions. However, they require specific temperatures and pH's to work optimally and produce the best outcome.
If an enzyme is placed in a lower than optimal pH, that means that there are more H+ ions, and the environment is more acidic. This influx of H+ ions can denature the peptide bonds within the enzyme, causing it to fold in a different way and be unable to carry out its normal duties. Hence, the activity of the enzyme will decrease significantly.
