A plants response to light is known asA. phototropism.

B. gravitropism.

C. thigmatropism.

D. heliotropism.

Answers

Answer 1
Answer: photos means light
tropos means turning

phototropism means turning towards the light

answer is A

(gravotropizom is like gravity, if you hold that kind of plant sideways, it will try to turn sidewyas, dunno thigmatropism, helio tropizom is turning toward the sun (but ther are other light sources other than sun))

What is the process called when the ribosome is conducted

Answers

The answer is translation.

Synthesis of proteins (translation) takes place in ribosomes. It is a molecular machine that accepts amino acids and makes proteins of them. Transfer RNA carries amino acids to the ribosome for protein synthesis. Anticodons of tRNA pair with codons of mRNA at the bottom of ribosomes. If the bases on two different RNAs are complementary, the amino acid disconnects from tRNA, and in ribosome, it is bound to the previous amino acid in the process of translation. 

Based on binomial classification system, the mosquito, anopheles punctulatus, is most closely related in structure toA. Clux pipiens
B. Anopheles quadrimaculatus
C. Ades aeqypti
D. Aedes sollicitans

Answers

b anopheles quadimaculatas

Final answer:

Anopheles punctulatus is most closely related to Anopheles quadrimaculatus according to the binomial classification system, because they belong to the same genus.

Explanation:

In the binomial classification system, organisms are named based on their genus and species. In this case, Anopheles punctulatus and Anopheles quadrimaculatus are both part of the Anopheles genus meaning they share a lot of similarities in term of structure and genetics. Therefore, Anopheles punctulatus is most closely related in structure to Anopheles quadrimaculatus.

Clux pipiens, Ades aeqypti, and Aedes sollicitans are species from other genus, hence they are not as closely related. Although they are all mosquitoes and have certain common features, they do not share as many similarities as within the same genus. Hence, Anopheles punctulatus has compared to other options, the most similarities with Anopheles quadrimaculatus.

How do pockets increase a lung´s surface area?

Answers

Answer:

many alveoli are present in the lungs with a shape that further increases surface area. Thin walls - alveolar walls are one cell thick providing gases with a short diffusion distance. Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface.

Explanation:

Acetylcholinesterase is an enzyme that catalyzes the breakdown of the neurotransmitter acetylcholine. Which of the following explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine?It would require a level of activation energy too high for acetylcholinesterase to react with other neurotransmitters.
      Binding with an alternate neurotransmitter would inhibit the reaction of the enzyme with acetylcholine.
      Reacting with another neurotransmitter would halt the production of the enzyme and raise the overall activation energy.
      Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered.

I think it might be the last one

"Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered" definitely best explains why acetylcholinesterase cannot be used to catalyze the breakdown of other neurotransmitters, like norepinephrine. You were right. Good job. :)

The fossil of a plant reveals that it produced spores that were used for reproduction. Which type of plant was it

Answers

Answer;

Seedless plant.


The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.


Explanation;

-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.

-These plants reproduce using haploid , unicellular spores instead of seeds.

-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.

dolphins
fish
baleen whales
clams
sponges

Answers

Animals that filter feeds are called filter feeder. These are a sub-group of feeding animals that eat by filtering the food from water. They use a specialized filtering system from their body to filter their food. Filter feeders are important in cleaning the water. Examples of these are baleen whales, clams, sponges and some fishes. Thus, all are animals which filter feeds except dolphins.
