Answer:
I think its because of the water pressure
Explanation:
Answer:
I'm guessing that it's because there isn't enough sunlight at the bottom of a lake. The water reflects light, and plants need enough sunlight since they use photosynthesis to get their energy.
some of the advantages of inorganic farming.
Answer:
With the use of pesticides, farming can be faster and it also detracts insects and weeds
Answer:
One advantage inorganic fertilizers offer is that they are fast acting. These nutrient-rich salts dissolve quickly and are immediately available to the plants depending on them to provide essential nourishment in the form of nitrogen, phosphorus and potassium.Organic fertilizers usually contain plant nutrients in low concentrations. Since many chemical/inorganic fertilizers are concentrated and very soluble, it's easier to apply too much and damage your plants. Fresh, non-composted manure can damage your plants as well, because some manure contains harmful amounts of salts

It attracts insects and other animals.
It moves the pollen to the ovaries.
It catches pollen.
It produces pollen.
Answer:
D
Explanation:
I did the assignment
The main function of the structure labeled A is it produces pollen. Therefore, the correct option is D.
What is a pollen?Pollen is a microscopic, powdery substance produced by the male reproductive organs of seed plants. It is made up of cells that contain the male gametes (reproductive cells) and is responsible for fertilizing the female reproductive cells (ovules) to produce seeds.
Pollen is often carried from one plant to another by wind, insects, or other animals, where it can then come into contact with the female reproductive organs of a different plant.
If the pollen comes into contact with a receptive ovule, it can fertilize the ovule and produce a seed. Therefore, the correct option is D.

is a chemical substance that organisms require to live.
Answer:
Nutrient
Explanation:
Nutrients are compounds in foods which are essential to life and health of living organisms, providing them with energy. They are the building blocks for repair and growth and substances necessary to regulate chemical processes. There are six major nutrients:
Carbohydrates,Lipids (fats),Proteins,Vitamins,Minerals,Water.The Serengeti region of Africa contains a population of cheetahs and a population of lions. Studies have shown that the cheetah population has very low genetic diversity, while the genetic diversity of the lion population is quite high. The cheetah population is also much smaller than the lion population. Both populations are vulnerable to infection with a particular virus that can be fatal in both species. What is the most likely outcome if both populations are infected with this virus?
A.
The cheetah population is more likely to survive because there are fewer individuals for the virus to attack.
B.
The lion population is more likely to survive because larger populations are immune to viruses.
C.
The cheetah population is more likely to survive because lower genetic diversity increases immunity to viruses.
D.
The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Answer:
D. The lion population is more likely to survive because it is more likely to have individuals with traits to combat the virus.
Explanation:
Since lions have greater genetic diversity it is likely that there's one or two lions that have a trait to resist or kill the virus thus won't be infected, whereas, since cheetah's have low genetic diversity and low population size it is likely that they have little to no chance to surviving this virus attack since the genetic makeup is similar among the members of cheetah species.

Why does light from the sun melt the plastic when light from the desk lamp does not
Answer:
Because the sun gives off a type of light that carries energy, and light from the desk lamp does not.
Explanation:
All of the energy from the Sun that reaches the Earth arrives as solar radiation, part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays. Radiation is one way to transfer heat.
Lamps are electrical devices that use electrical energy in the form of electrical current.

Which type of selection leads to increased phenotypic and genetic variation? directional selection disruptive selection stabilizing selection species selection
Answer:
diruptive selection/ diversifying selection
Explanation:
disruptive selection often leads to more variations in species
The circumstance that concludes whether the organism will be able to accommodate and endure in the changed conditions is called selection.
The correct answer is:
Option B. Disruptive selection.
This can be explained by:
Disruptive or diversifying adaptation occurs when there is a change in population genetics in which the traits are valued over intermediates.This type of assortment supports either the dominant or the recessive trait but do not favour intermediates.For example, in selection between tall, short or intermediate organisms the tall and short will be selected over the medium heightened organism.Therefore, disruptive selection will lead to increased phenotypic and genetic variation.

Who first suggested the theory of evolution by natural selection?
O A. Charles Darwin
B. Wilhelm Weinberg
C. Gregor Mendel
D. Thomas Malthus
Charles Darwin first suggested the theory of evolution by natural selection. Therefore, option (A) is correct.
Who was Charles Darwin?Darwin was a British naturalist who conducted extensive research and observation during his travels around the world, and his work culminated in the publication of "On the Origin of Species" in 1859. In this seminal work, Darwin proposed that species evolve over time through a process he called natural selection, which involves the differential survival and reproduction of individuals with advantageous traits.
This theory challenged the prevailing view of species as unchanging, fixed entities and revolutionized the field of biology. While Darwin was not the first to propose the idea of evolution, his theory of natural selection provided a mechanism to explain how it occurs and remains one of the most important and influential ideas in the history of science.

D= photosynthesis
The given process shown in the image is cell reproduction. Cell reproduction takes place by mitosis and meiosis.
What is cell reproduction?Mitosis and meiosis are the two distinct processes of cell division. When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body. The cell division process known as meiosis is what produces egg and sperm cells.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis.
Meiosis, the second sort of cell division, makes sure that each generation of people has the same number of chromosomes.

Answer:
1,2 × 10⁹ : 1
Explanation:
In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40 million and 1.2 billion sperm cells in a single ejaculation.
Explanation:
Therefore, a standard sperm to egg ratio of 1 × 105 sperm per egg is recommended for fertilization in Atlantic cod. At the 1 × 103:1, 5 × 103:1, and 1 × 104:1 sperm to egg ratios maximum fertilization occurred after 30 min sperm to egg contact time.

B. Geocentric
Explanation:
Geo means Earth, and centric means "in the center". So a geocentric model of the solar system would mean the Earth were at the center of the solar system, with the Sun and planets revolving around the Earth.

During the process of mountain building, earthquakes sometimes occur along continental-continental convergent boundaries. Which statement best describes the motion of the plates along these boundaries that causes the earthquakes?
Answer:
Although you have not put the answer options, the movement of the plates in the situation shown above occurs with the approach of their continental plates that collide and bend due to the impact.
Explanation:
The converging movement of the plates indicates that two plates are moving towards each other until they collide. When these two plates are continental, the movement is called continental-continental convergent.
As the two continental plates have the same density, the impact between the two causes them to bend and not sink into each other.
