determine approximately how much total energy is lost from a three step food chain if 1000 calories enter at the autotroph level
MariettaO [177]
So remember that each level receives 10% of energy from the level before it. So autographs have the 1000 calories, the primary consumers would only get 10% which is 100 calories meaning 900 calories were lost. The secondary consumer would only get 10% which is 10 calories meaning an additional 90 calories were lost. The Total lost amount is 990 calories

guajiro [1.7K]

Hello. You forgot to enter the answer options. The answer options are in the figure attached below:

Answer:

the option D is the right answer.

Explanation:

Option D shows a pathway where activation of the receptor would lead to an increase in gene expression. This is because in this option we can see that the transcription regulator is decreasing gene expression, but there is a receptor that is activated and that has the ability to inhibit the pathway, allowing the selected gene to be expressed efficiently. This is because the pathway shows two inhibitory steps, when this happens an activation is performed.

Polar bear somatic cells contain 74 total chromosomes. how many chromosomes would a polar bear egg cell contain?
PtichkaEL [24]

Answer:

The correct answer would be 37.

Egg or sperm or gametes are cells produced by the process of meiosis and carry half the number of chromosome (n) present in a parental cell (2n).

Meiosis is a type of cell division which results in the formation of four daughter cells each having exactly half the number of chromosome present in  parent cell.

The sperm unite or fertilize with egg which restore the chromosome number (2n) in the zygote.

How do ingestive protists obtain food?
OLga [1]
<span>Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb.  Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules  across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers  like photosynthetic protists  use light energy to manufacture  their own food.</span>
