If there is a 90% chance of rain tomorrow and a 70% chance of wind and rain, how many percent is the probability that it is windy, given that it is rainy? Round your answer to the nearest percent. A) 67%
B) 71%
C) 33%
D) 78%

Answers

You have the chance of rain

P(R) = 0.9

And the chance of wind and rain

P(R∩ W)=0.7

The probabilities of windy weather is

P(W)=(P(R∩W))/(P(R))=(0.7)/(0.9)=0.78

The correct answer then is D) 78%

Answer:

78%

Explanation:

The combustion of glucose ultimately involves the transfer of electrons to oxygen (O2). In biological systems, this takes place without a large increase in temperature. Which of the following statements about this process in biological systems is true? 1) Coupled oxidation-reduction reactions occur with electrons being passed to intermediate electron carriers. 2) The process involves the transfer of 12 pairs of electrons to oxygen. 3) The transfer of electrons from intermediate electron carriers to molecular oxygen is catalyzed by the electron transport chain. 4) Though the process is a controlled oxidation, some energy is lost.

The photosynthetic mechanism of the plants make it possible for them to have and create food in order to survive but as they make this "food" which is glucose, the by-product oxygen is created which hence is beneficial to all life forms of heterotrophs. 

We develop connections between brain cells through what?

Answers

Answer:

synapses

Explanation:

Brain cells have the efficiency to talk to its nearby cells and thus send or receive pre informed signals across connections. This process of intra brain cell communication is called as synapses

As we grow our brain organizes  the previously established synaptic pathways and shuts down less-active, inefficient synapses

Neurons (brain cells) preserve their most active connections with the nearby cells and thus lapse the remaining synapses

SIRP alpha protein (found on the surface of cells) helps in cementing the active synaptic connections between brain cells

We develop connections between brain cells through a process called synaptic plasticity and  is the ability of the connections between neurons (brain cells) to change  in strength and structure

what  are two main types of synaptic plasticity?

Long-Term Potentiation (LTP): LTP is a process by which synaptic connections become stronger and more efficient over time. It occurs when a synapse is repeatedly and persistently stimulated, leading to an increase in the release of neurotransmitters and an enhancement of the postsynaptic neuron's responsiveness to those neurotransmitters. LTP is believed to be one of the cellular mechanisms underlying learning and memory.

Long-Term Depression (LTD): LTD is the opposite of LTP, where synaptic connections become weaker and less effective. It occurs when a synapse is weakly stimulated or not used for an extended period, resulting in a decrease in neurotransmitter release and a reduction in the postsynaptic neuron's responsiveness.

When cleaning up water pollution in a large lake or river, it is important to clean up the entire??

Answers

When cleaning up water pollution in a large lake or river, it is important to clean up the entire watershed. It is a basin-like landform defined by highpoints and ridgelines that descend into lower elevations and stream valleys. This is because pollution can be transfered to other areas of the lake or the river when this part is not cleaned well.

Which of the following statements does NOT contribute to the evidence in support of evolution?(A) Sequences of fossils have been found that show a gradual series of changes in form among organisms.
(B) Species thought to be related through evolution from a common ancestor show many anatomical similarities.
(C) The stages of embryological development in animals are quite similar among highly diverse types of organisms.
(D) Similarities in chromosome structure, DNA sequence, and amino acid sequence suggest relationships among organisms descending through evolution from a common ancestor.
(E) The most well adapted individuals do not always produce the most fit offspring.

Answers

Definitely option E! This refers to exceptions to the 'survival of the fittest' - but the theory still holds despite these anomalies.
