Which substances are needed to make food in plants?.
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

Why are meerkats affected by the plant population?
Answer:
They largely depend on it for survival as meerkats are omnivores.
Explanation:
The combined effects of hotter and drier summers and fewer plants would threaten the persistence of the meerkat population. Since they eat plants and other living bugs that usually hang out in plant-abundant areas, their [meerkats] survival depends on the range of plants near them.
I just need a description of what role bees play in pollination (it’s horticulture) btw
Answer:
Bees are essential for the growth of flowers and plants. They use the process of pollination where they transfer small grains of pollen from one flower of the same plant to another flower of the same species. This pollen transfer helps the flowers to get continuous growth.
Explanation:
Answer:
In the nature, plants reproduce s*exually but unlike many organisms, they do not directly mate with their opposite gender for reproduction. Their mechanism of reproduction in short is that male flowers produce pollens (yellow, powdery type thing) in thei anthers (male fower gamet) and when these pollens get contact with the female flower's stigma, the pollen fuses with the ovule and produces a fruit containing the seed.
Now how do we get these pollens moving from anthers to stigma? There are two ways. The first is by wind, when wind blows, it carries the lightweight pollens through the air and it falls onto a female flower.
the second one is by bees.
Those flowers produce nectar deep in the flower which can be sensed by bees. Bees enter the flower to collect the nectar while pollens are stuck on to its body. The bees travel to another flower for collecting nectar and when they do, the pollens from the body enter the stigma.
Why is hair follicle and hair shaft important ?
Answer:
A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.

During the cell cycle, normal cells exit the G1 phase and enter the Go phase where they rest. Typically,
cells will reenter the cycle at G1 prior to going on to S phase. However, abnormal cells such as cancer
cells, may not be allowed to enter the Go phase to rest.
As a result, these cells will most likely -
F. mutate during G2 phase
G. continuously repeat the cycle
H. die after DNA replication
J. fail to complete mitosis
Abnormal cells such as cancer cells, may not be allowed to enter the G0 phase to rest. These cells will most likely continuously repeat the cell cycle.
What do you mean by Cell cycle?The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
The abnormal cell undergoes a repeated cell cycle because they express an enzyme called telomerase that switches the wearing down of chromosome ends.
This happens normally in the cell cycle, and after multiple repeated cycles, such abnormal cell undergoes apoptosis.
Therefore, abnormal cells such as cancer cells, may not be allowed to enter the G0 phase to rest. These cells will most likely continuously repeat the cell cycle.

Sequence the steps in how a nerve impulse moves from one neuron to another neuron, by writing the numbers 1 to 5 in the squares to the left of the steps.
Help me please.
The steps in how a nerve impulse moves from one neuron to another neuron can be describe as dendrite – cell body – axon.
How does the nerve impulse occur?The nerve impulse starts when the neuron experiences a stimulus strong enough to trigger it. This happens when a membrane is at resting potential, a condition where the inner surface of the membrane is negatively charged relative to the outer surface.
In this case, the correct steps will be in a neuron, the stimuli always propagate in the same direction: they are received by the dendrites, travel through the cell body, travel along the axon and, from the end of this, are passed to the next cell (dendrite – cell body – axon).

Based on the graph, it can be concluded that the isotope which is most likely to be found with 6.25% of its original amount in 6 billion years is
Uranium-238
Thorium-235
Potassium-40
Rubidium-87
Potassium is most likely to be found with 6.25% of its original amount in 6 billion years because the half life of Potassium-40 is 1-1.5 billion years in graph. Thus the correct option is C.
If it half in 1 to1.5 billion years = 50% gain
1-1.5 billion years = 25%. gain
If we do that 2 more times we will get 12.5% and then 6.25% gain.
What is half life?
Half life is defined as the time required for half of the atoms of a radioactive substance to become disintegrated.
Our estimate is about 1-1.5 billion years so repeating that about 4 times we get around 4-6 billion years for it to gain 6.25%. From this it can be concluded that Potassium-40 as since it comes the closest to remaining at 6.25% its original amount after approximately 6 billion years.

According to the research, most of the carbon quickly enters back into the atmosphere in the form of carbon dioxide.
What is the carbon cycle?It is the process that describes the flow of carbon (in the form, for example, of carbon dioxide) in the atmosphere, the ocean, the terrestrial biosphere.
Thus, the CO2 in the atmosphere passes through photosynthesis to the plants, also the cycles of respiration and microbial decomposition intervene, which release new CO2 in gaseous form into the atmosphere.

Bicarbonate ions present in body performs a variety of functions, in blood it carries carbon dioxide. Its other functions include keeping the balance of acids and bases in the body. It acts as a buffer.
What is a buffer?Buffer is a type of solution that resists pH change either by the addition of acid or base.
Bicarbonate is a base, which the body requires to keep a normal acid-base (pH) balance.
This balance prevents the body from having too much acid means maintaining buffer. The lungs and kidneys helps to keep a normal blood pH by removing excess acid.

Answer: Meiosis
Explanation:
Meiosis creates gamete "daughter cells" that have half the chromosomes as a normal cell that would be created during mitosis, which is the division and reproduction of identical cells from the parent. In humans, a regular 46 chromosome cell divides through meiosis to create gametes with 23 chromosomes. This is important to be sure that an organism that is made through reproduction with sperm and egg has the correct number of chromosomes.
