hello help please i’ll mark brainliest!!!

Answer:

The correct answer is -

a) A plant cell B animal cell

b) nucleus

C) Vacuole

Explanation:

In plant cells, there is a large vacant space present in the center which is actually a vacuole that plays role in various types such as nutrients storage, water balance. In plant cells, a dense round structure present at one side of the cell known as the nucleus.

In animal cells, the vacuoles are absent or very small however the round dense structure of the nucleus is present in the center of the cell. Thus, the correct answer is -

a) A plant cell B animal cell

b) nucleus

C) Vacuole

Answer:

true

The statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others. So, the correct option is D.

Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.

The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.

Therefore, the statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others.

Answer:

metals

Explanation:

In the periodic table, elements are classified as metals, nonmetals, and metalloids according to their properties and their specific location within the periodic table.

The periodic table is also called the periodic table of the elements which is defined as the arrangement of rows and columns of the chemical elements widely used in chemistry, physics and other sciences and usually represented by chemical symbols.

The elements of the periodic table are classified into groups based on the chemical and reactive properties of the elements where the three major groups are metals, nonmetals and metalloids. The metals in the left and bottom parts of the table give up electrons in chemical bonds.

Thus, in the periodic table, elements are classified as metals, nonmetals, and metalloids according to their properties and their specific location within the periodic table.

A Synapse is a small gap at the end of a neuron that allows a signal to pass from one neuron to the next. Synapses are found where nerve cells connect with other nerve cells. Synapses are the key to the brain's function.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

The term synapse was first introduced in 1897 by Michael Foster in his "Textbook of Physiology" and derived from the Greek synapsis, meaning "conjunction."

Disadvantages of wind energy

Unpredictable. Perhaps the biggest disadvantage to wind energy is that it cannot be produced consistently. ...

Threat to wildlife. Wind energy does not cause environmental problems through greenhouse gas emissions, however, turbines can have an impact on wildlife. ...

Noise. ...

Looks. ...

Location limitations.

ᴍᴀʀᴋ ᴀs ʙʀᴀɪɴʟɪᴇsᴛ

Answer:

Wind energy is one of the most commonly used types of renewable energy. and also happens to be one of our fastest-growing sources of electricity. However, while there are a number of environmental benefits to using wind energy, there are some downsides. On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them. Similar to solar power, wind power is also intermittent, meaning that turbines are reliant on weather and therefore aren’t capable of generating electricity 24/7. Unlike coal, natural gas, or oil, generating electricity from wind doesn’t result in greenhouse gas emissions. While there are some environmental considerations that come with building large wind farms, once operational, wind turbines themselves don’t require burning any fossil fuels to operate.

Additionally, wind energy is completely renewable and will never run out. In opposition to traditional fossil fuels resources that replenish very slowly, wind naturally occurs in our atmosphere, and we don’t have to worry about supply issues in the future.

As far as upfront costs go, wind farms or individual turbines can be expensive to install. However, once up and running, operating costs are relatively low; their fuel (wind) is free, and the turbines don’t require too much maintenance over the course of their lifetime.

A wind turbine’s effectiveness in generating electricity depends on the weather; thus, it can be difficult to predict exactly how much electricity a wind turbine will generate over time. If wind speeds are too low on any given day, the turbine’s rotor won’t spin.  

This means wind energy isn’t always available for dispatch in times of peak electricity demand. In order to use wind energy exclusively, wind turbines need to be paired with some sort of energy storage technology.

One of the biggest downsides of wind energy is the noise and visual pollution. Wind turbines can be noisy when operating, as a result of both the mechanical operation and the wind vortex that’s created when the blades are rotating. Additionally, because wind turbines need to be built up high enough to capture a good amount of wind, the turbines can often interrupt otherwise scenic landscapes, such as mountain ranges, lakes, oceans, and more.

Answer:

Friction and gravity are at work in each picture. Explain how each are at work and how they work together. Balanced forces - Two or more opposite forces are balanced forces if their effects cancel each other and do not cause a change in an object's motion.

Explanation:

Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

She should immediately rinse or flush her eyes with water.

Explanation:

One of the most important precautionary measure to be taken when working with explosive chemicals in the laboratory is the use of safety goggles. However, in this case, Maria claimed that she could not see through the safety goggles and wore them on top of her head rather than over her eyes.

Maria accidentally splashed some chemicals into her eyes while trying to pour it into a beaker. The primary or initial response to this happening is to immediately FLUSH OR RINSE her eyes with water. This will flush away the chemical from her eyes before it can have its detrimental effect.

Answer:

proceed to the eye wash station, open her eyes, and rinse them for at least 15 minutes

The correct answer would be -

FSH - used as fertility drugs to makes egg mature.

LS - stimulates the release of eggs.

Oestrogen - causes the lining of the womb to break down.

Explanation:

FSH is a hormone released from the pituitary gland and is the abbreviation of Follicle-stimulating hormone which controls the menstrual cycle and growth of eggs in ovaries. It is also used as a fertility drug that promotes the growth of eggs to mature it.

LS or Luteinising hormone is the hormone that is released from the pituitary gland and promotes the surge of the release of eggs.

Oestrogen is the hormone that helps females during puberty during the menstrual cycle to breakdown the lining of the womb.

Because dense minerals are heavier and drop to the stream bottom, lighter minerals are carried along in the current of the stream.
