Which kingdom(s) include organisms that are autotrophic or heterotrophic?
I hope this will help you:)
Autotrophic organisms are found in kingdom planted
Heterotrophic organisms are found in kingdom animalia
Kingdom monerans has some organisms like Cyanobacteria that can carry out photosynthesis so they are autotrophswhile the other main category of monerans is not capable of photosynthesis so are heterotrophs so this kingdom includes both o gains s
Kingdom protist are heterotrophs and autotrophs because some can prepare food while others cannot
Kingdom fungi has some organisms that can carry out photosynthesis like algae
while other are heterotrophs
de kingdoms where de aiutotrophs nd heterophic belong is known to be bacteria..there is also kingdoms where in dey r also autotrhoic nd dis is plantae kingdom also dere r kingdom there r only hetetrpohs nd these r animalia nd fungai
Which of the following is true about the speed of light?O it is a constant when the light is traveling in a vacuum. O It speeds up or slows down depending on the observer. O It is slowest in a vacuum. O lt varies depending on the color of the light.
It is a constant when the light is traveling in a vacuum.
Describe how an allosteric enzyme works.
Allosteric enzymes bind at different site from the substrate binding site.
The activities of some enzymes, particularly those which form a part of a chain of reactions like metabolic pathways, are regulated internally. Some specific low molecular weight substances such as the products of another enzyme further on in the chain, acts as the inhibitor. Such a modulator substance binds with a specific site of the enzyme different from the substrate binding site. This binding increases or decreases the enzyme action. Such enzymes are called allosteric enzymes and the site at which they bind is called allosteric site.
Example: Hexokinase is an enzymes which converts glucose to glucose-6-phosphate in glycolysis. Decline in the enzyme activity by the allosteric effect of the product is called feedback mechanism, like the allosteric inhibition of hexokinase by glucose-6-phosphate,
Ten grams of hamburger were added to 90 ml of sterile buffer.This was mixed well in a blender. One-tenth of a ml of this slurry was added to 9.9 ml of sterile buffer. After thorough mixing, this suspension was further diluted by a 1/100 dilution followed by a 1/10 dilution. One-tenth of a ml of this final dilution was plated on agar plates. After incubation, 52 colonies were present. How many colony-forming units were present in the total 10 gram sample of hamburger?
5.2 × 10 ⁹ cfus
Using the dilution factors
0.1 ml of the final dilution has 52 colonies
1 ml will have approximately 520 colonies
10 ml of the final sample will have 5200 colonies
at 1 / 100 dilution
1 ml of the sample will have 5200 colonies
100 ml of the sample will have 520000 colonies
1 ml of the 0.1 ml + 9.9 ml has 520000 colonies
10 ml will have 5200000
at the second stage of the dilution
0.1 ml of the slurry had 5200000 colonies
1 ml will have 52000000 colonies
10 ml will have 520000000 colonies
100 ml of the initial sample ( 10 grams + 90 ml ) = 5200000000 colonies =
5.2 × 10 ⁹ cfu
Which of these fields of study would be the most useful for someone whowants to examine the effects of deforestation on native species? A. Ecology B. Chemistry C. Meteorology D. Geophysics
Ecology, the definition of ecology is most summed up by studying organisms and their surrounding and how it effects them
The answer will be A. Ecology
Fatima suffered a brain injury and is having difficulty understanding spoken language. Which area of her brain is most likely to have beendamaged? O Broca's area Wernicke's area Motor cortex Cerebellum
Wernicke's area is most likely to have been damaged in Fatima's case.
The area of Fatima's brain most likely to have been damaged is Wernicke's area. Wernicke's area is responsible for the comprehension and production of spoken and written language. Damage to this area can result in difficulties understanding spoken language, as in Fatima's case. This area is located in the left hemisphere of the brain, near the auditory cortex.
