Auxins cause cells to grow ___. A. Longer on the sunny side of the stem. B. Shorter on the sunny side of the stem . C.shorter on the shaded side of the stem .d. Longer on the shades side of the stem
Answer:
D. Longer on the shaded side of the stem
Explanation:
Auxin is a plant hormone that promotes cell growth and elongation in plant stems.
It causes the cells to grow longer on the shaded side of the stem.
This growth allows for the plant to grow in the direction of the light source it has.
So, the correct answer is D. Longer on the shaded side of the stem

A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation
Answer:
The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero
Explanation:
Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).

how energy transformations involved in photosynthesis are related to energy transformation involved in cellular respiration
Answer:
Photosynthesis is the process by which energy is converted to chemical energy in plant cells. In cellular respiration plants use the chemical energy stored during photosynthesis in basic life processes. During both photosynthesis and cellular respiration, energy is converted.

Which of the following defines an ecological succession
Answer:Ecological succession is the process that describes how the structure of a biological community (that is, an interacting group of various species in a desert, forest, grassland, marine environment, and so on) changes over time. The structure of this community becomes more complex as new species arrive on the scene.

Drag a number and symbol to represent the amount of time Carl worked on problems.
___ ___ ____
Answer:
25 - m
Explanation:
If Carl worked m less than 25, 25 - m would represent the amount of time Davis worked minus the difference in the amount of time that he and Carl worked, which would equal the amount of time Carl worked.

Why is it more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain?
the trophic pyramid is the reason
what the trophic pyramid is: Trophic pyramid, also called an energy pyramid, showing the progression of food energy. The pyramid base contains producers, organisms that make their own food from inorganic substances. All other organisms in the pyramid are consumers
- predators get little energy from the prey they eat so they must consume multiple prey
It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.
The trophic levels of food chainThe food chain is defined as a feeding pathway that consists of similar organisms that are placed in the same trophic levels.
Trophic levels in a food chain are those levels that is occupied by a group of organisms that have a similar feeding mode.
The plants which are the producers are at the lower trophic level while the carnivores are at the higher trophic levels.
The carnivores eats meat from other animals but not plant or plant products which obtain direct energy from sunlight.
Therefore, It is more difficult for top carnivores to obtain sufficient energy resources than it is for animals lower on the food chain because the higher trophic levels have less energy than the lower ones.

Explanation:
You put a cat in an open cage with cat food, water, and a litter box (where the cat poops and urinates). The cage cat water food litter box weighs 2000 grams. Two weeks later, the cat has eaten all the food, has drunk all the water, and has grown a little bit bigger. The cat's waste (urine and poop) is still in the litter box. How much would you expect the cage cat litter box with poop and urine to weigh now
