Extremophiles have been found flourishing in hot, acidic sulfur springs, around hydrothermal vents deep in the ocean, and in soi

l with high levels of toxic metals. What does the existence of life in such extreme environments say about the possibility of life on other planets?

Answer:

Life may exist in extreme conditions

Explanation:

The conditions in other planets do not normally resemble those on Earth. They are commonly much hotter or colder and are filled with toxic gases or liquids. It would be easy to think that life could not exist in those inhospitable places, but when we see how life on our own planet has adapted to the harshest enironments we have to think again and consider that life could exist in those extreme planets.

By about ____ months of age, different circuits in the brain begin to control infants’ looking at faces, allowing infants to dis
mojhsa [17]

Answer: 2-3

Explanation:

A biological neural network or neural circuit is a set of ordered synaptic connections that occur as a result of the binding of neurons to others in their corresponding regions following neural migration. At birth, a baby has an average of 100 billion neurons, but few neural connections. These will multiply as the child grows, through environmental, sensory, cognitive and movement stimulation. <u>Stimulating mobility and physical activity also has a positive effect on cognitive functioning by modifying the activity of certain brain areas</u>. Physical exercise has beneficial effects on brain function, such as promoting neuroplasticity and increasing learning and memory performance, which may be due to increased expression of various neural growth factors.

<u>Finally, environmental stimulation is basic for harmonious brain development and for laying the neurophysiological foundations of our children's future brains. </u>Thus, there are many mechanisms that nature has at its disposal to prevent babies from being left helpless.  All of them favour their relationship with adults and thus their neurons, at a time of maximum growth of their extensions, can form the brain circuits that allow the acquisitions that make them advance in their neurodevelopment. If babies do not receive from their adults sufficient affection and attention, brain growth will be much less and their neurodevelopment will inevitably be delayed, because what makes the brain grow and change is precisely the creation of new circuits as it learns new things, and those who can learn most are the most experienced. By aboyt 2-3 months is when circuits of the brain begin to be created.

Which describes a climate effect on the rate of weathering?
tester [92]

Answer:

Cold climates favor mechanical weathering.

Explanation:

A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering. The warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering

A hormone attaches to a target cell at a receptor protein. What do you know about this hormone?
charle [14.2K]
So, this hormone is a non-steroid hormone.  Steroid hormones are fat soluble and can pass directly into the cell to affect the nucleus.

Non-steroid hormones bind to the receptor and trigger a chemical change within the cell without ever entering the cell, or the nucleus.

The answer is: It will not enter the nucleus

An example of a population in which evolution could
Snezhnost [94]

An example of a population in which evolution could  take place in a relatively short period of time could be pathogenic bacteria exposed to antibiotics.

Answer: Option A

<u>Explanation:</u>

Evolution if takes place within a short period of time say the next generation that is called as micro evolution. This is caused when a specific organism exposed in a different environment at once modifies its genes to suit the new environment.  This phenomenon can be very well seen in the pathogenic bacteria which are exposed to antibiotics.

When an antibiotic is prescribed to bacteria initially it nullifies its effect by destroying it. When continuously exposed to a certain antibiotic some bacteria dies but there are few which becomes resistant to it and survives. This on the other hand multiplies producing a generation that can’t be touched by the antibiotic.
