Can someone explain to me what flowering time is?? And how to control flowering time???
Answer:
Flowering time refers to the amount of time the plants will spend in the flowering stage. It begins when you switch your lights to a 12/12 schedule and ends when the buds are ready to harvest. ... In this case, the actual flowering time (as understood by most breeders) would be 2-3 weeks longer. so the flowers will spend time in differents parts of different stages
A dramatic change in the life cycle of plants is the transition to flowering, which is triggered by both environmental signals, as temperature and photoperiod, and endogenous stimuli. so it would just 2 be to watch over there environment and what u are doing 2 them
Explanation:
Answer:
Flowering time is the amount of time that a plant will stay in it's flowering stage. the flowering time of its life will reach 12 hours or less of light per day.
It's controlled by environmental conditions and development regulations, such as temperature, photoperiod and endogenous stimuli

What is the relevance of osmosis to the root hair cells?
Answer:
absorb water from the soil by osmosis.
Explanation:
Root hair cells
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption

The concentration of lactic acid in the student's
muscle tissue was most likely greatest during trial
A) A В) В
C) C D) D
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

On the internet, read about the Clean Air Act of 1990:
a. Summarize what it says.
b. How should it help with the problem of acid rain?
c. How successful has it been in reducing the harmful chemicals from the burning of fossil fuels that cause acid rain?
d. What can you do personally to help alleviate the problem of acid rain?
3. Find two examples of actual ecological places that have been affected by acid rain. Tell their location and describe what happened.
Acid rain is formed when gases such as SOx and NOx are released by burning fossil fuels.
The clean air act has to do with the reduction of the gases that lead to acid rain such as SOx and NOx. The full implementation of the legislation ought to reduce the occurrence of acid rain.
However, since the introduction of the act in 1990, reduction in acid gas pollution has not reduced significantly since acid gases are still produced by the burning of fossil fuels.
To help alleviate the problem of acid rain, I must reduce my use of gasoline powered vehicles and embrace vehicles that depend on renewable energy sources and clean fuels such as hydrogen fuel.
Eastern Europe countries such as Poland and Scandinavia have been severely affected by acid rain. The pH of water bodies in these areas are unusually low.

(giving brainliest if u help)The following are steps in an investigation into electrically charged objects.
Step #1: Blow up a balloon.
Step #2: Rub the balloon against your hair.
Step #3: Rub a plastic fork against your hair.
Step #4: Bring the two objects together and observe what happens.
Which steps are required to charge the objects?
A: Step 1 and 2
B: step 2 and 3
C: step 3 and 4
D: step 1 and 4
Answer:
B, Step 2 and 3.
Explanation:
Once you rub a balloon against your hair and try to slowly remove it, your hair will be pulled towards the balloon like a magnet. This is because the balloon charged your hair and your hair was then able to get attracted to the balloon, the same applies to the fork.

Why are hydrogen bonding and popularity so important for water molecules?
Answer:
they are so important because the presence of hydrogen bonds also makes water molecules more 'sticky' or in scientific terms cohesive and adhesive. The small charges on the water molecules allows them to stick together which is why water has a 'skin' that small insects can walk on, and also explains why water can be sucked up a straw so easily.

“Inter” means inside, so I’m guessing it would relate to the organisms being of the same species. “Intra” means outside. And invasive just doesn’t make any sense.

drag the labels to their appropriate locations on the diagram of the neurons below. use targets of group 1 to indicate the components of neurons. use targets of group 2 to indicate the locations of gated ion channels.
Neurons are cells in chauge of synapsis. a)cell body / b)myelin sheath / c)synaptic terminal / d)axon hillock / e)nucleus / f)location of voltage-gated channels / g)location of ligans-gated channels / h)axon / i)dendrite
-------------------------------
Most neurons are composed of a cell body, dendrites that are cytoplasmic extensions that receive impulses from other cells, and an axon that is a long formation capable of conducting the electrochemical signals.
Neurons transmit nervous impulses.
Every neuron forms connections with other neurons. These connections are known as synapsis.
During synapsis, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the other neuron.
Once it reaches the target, it binds to its receptors in the postsynaptic membrane, causing ion channels to open.
This binding produces a depolarization of the cell called an excitatory postsynaptic potential.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
When the electrical stimulus is applied to the axon's membrane, it produces depolarization by activating the sodium voltage-dependent channels all along the axon.
Besides, there is an increase in sodium permeability.
Depolarization propagates to inactivated regions adjacent to the membrane opening more sodium channels.
The fiber diameter and the conduction velocity are closely related, exhibiting a directly proportional relationship. Mielinized fibers are thick, and their conduction velocities are very fast.
The conduction velocity sharply increases in myelinated fibers. This is because of the high concentrations of sodium channels in the Ranvier nodes that are not myelinated areas, and the diameter of the axon becomes thinner.
