How many valence electrons are in an atom of each element in Group 15 in the periodic table?
Answer:
5 valence electrons.
Explanation:
Group 15 can also be called group 5A, meaning that elements in this column contain 5 valence electrons.
The periodic table's Group 15, often known as the Nitrogen Group, contains elements that have five valence electrons.
Nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), and bismuth (Bi) are among the elements that make up group 15. The 2p orbital is where the valence electrons of these elements are situated.
All Group 15 elements, with the exception of nitrogen, which has only 3 valence electrons, have 5 valence electrons since the valence shell can only accommodate a maximum of 8 electrons.
These elements can easily establish covalent connections with other elements thanks to their five valence electrons.
Thus, this characteristic helps explain their chemical reactivity and capacity to create a wide range of chemicals.

What are two reasons bees are important beyond making honey
Answer:
Bees are perfectly adapted to pollinate, helping plants grow, breed and produce food. They do so by transferring pollen between flowering plants and so keep the cycle of life turning.
The vast majority of plants we need for food rely on pollination, especially by bees: from almonds and vanilla and apples to squashes. Bees also pollinate around 80% of wildflowers in Europe, so our countryside would be far less interesting and beautiful without them.
Answer:
bees provide air and food but 1 third of all food we eat comes from bees

Which is true of the regions near earth’s equator
Answer:
They are more likely to have high temperatures
Explanation:
The major cause of global warming is
sun flare pollution
biological magnification
mono-culture farming
burning fossil fuels
Hey there!
Answer:
Burning fossil fuels
Explanation:
Greenhouse gases are the main human causes of global warming.They basically act like a warm blanket around the earth and trap heat. Causing the earth to get warmer and temperatures to rise.
The two main greenhouse gases we add to the air are methane and carbon dioxide.
The main source of carbon dioxide is the burning of coal,oil,gas and petrol(fossil fuels)in power stations.
We produce far more carbon dioxide than any other greenhouse gas. And its production has been on the rise since the industrial revolution.
So the burning of fossil fuels resulting in carbon dioxide is the main cause of global warming.

The temperature of the areas surrounding El Campo before Storm 1 and before Storm 2 was about 15°C, and there was the same amount of water vapor in the air.
Storm 2 had more rainfall than Storm 1.
What were the conditions before Storm 2, and why did more rainfall with those conditions?
i will give 30 pts PLZ ANSWER ASAP
Answers:
The temperature of the surronding areas of El Campo is the same.
Before storm 2, El Campo will have been warmer than before Storm 1 and windy. Wind pushed the warmer air parcel even higher and the air parcel lost more energy.
Explanation:
Weather patterns refers to repeated way weather occur for days, or weeks or for a time. Weather pattern is caused by heat from the sun and movement from the air.
In El Campo, the temperature of the surronding area is the same.
If an air parcel is higher than the surronding air, it will rise. When the air parcel has higher temperature, it will rise very high and loses energy which result in rainfall.
The temperature of the surrounding areas of El Campo should be the same. Prior to storm 2, El Campo will have been warmer as compared to before Storm 1 and windy.
What are weather patterns?It means the repeated way with respect to the weather that should be arise for days or in can be weeks. It should be caused by heat from the sun and the movement can be done from the air.
In the case when the air parcel should be more than the surrounding air so it will rise. At the time when the air parcel contains the high temperature so it will increase very high also the energy should be lost that leads in rainfall.

When building a spacecraft what are the 3 things NASA is most concerned about?
Answer:
If the ship is strong enough to support the launch. If the ship can withstand high pressure and temperature rates. If the material is resistant and light at the same time.Explanation:
When a spacecraft is built, many tests must be carried out over the years to prove that the spacecraft has the ability to launch into space and fulfill its mission efficiently. In addition to supporting the launch, these ships need to be built in a way that will withstand space conditions that are very different from terrestrial conditions.
For this reason, there is a concern if the ship can withstand extreme situations of temperature, pressure, gravity, weight, among others. In summary, we can say that three of the biggest concerns that NASA has in building spaceships are:
If the ship is strong enough to support the launch. If the ship can withstand high pressure and temperature rates. If the material is resistant and light at the same time.HELP ME PLS!

a. Adaptation
b. Allele
c. Variation
d. Selection
Answer:
Adaptation
Explanation:
a change or the process of change by which an organism or species becomes better suited to its environment.
A trait that helps an organism to survive and reproduce is called adaptation. The correct option is a.
What is adaptation?An organism can survive under adverse environmental conditions by changing its shape, physiology, and genetic makeup through the process of adaptation. This happens as a result of natural selection and evolution.
An organism is said to be adapting when it makes changes in response to its environment. These changes help organisms to survive in extreme conditions.
In biology, adaptation is the process by which a species adjusts to its environment; it results from natural selection operating over many generations on heritable variation.
Therefore, the correct option is a. Adaptation.

What do oestrogen and progesterone do in the menstrual cycle
Answer:
Oestrogen and progesterone in the control of the menstrual cycle. Progesterone maintains the uterus lining (the thickness of the uterus wall). If the egg has not been fertilised, the corpus luteum dies and progesterone levels drop. This causes menstruation, where the uterus lining breaks down - this is known as having a period.

What type of plate boundary is illustrated in the image?
The type of plate boundary illustrated in the image is convergent boundary plates.
What is the convergent boundary?An area where two plates converge is referred to as a convergent border. The borders of one or both colliding plates may bow up into mountain ranges as a result of the impact, or one plate may bend down into a deep undersea trench.
Convergent boundary plates are the kind of plate border that is depicted in the image. The edges of a plate boundary are those of two plates that are either colliding, moving apart or meeting.
Activities like mountain-building, earthquakes, and volcanoes do happen at plate borders.
Therefore, the border where two plates are colliding is known as a convergence boundary.
