where is the fertilization in plant take place
Answers
Fertilization takes part in the ovary of a female flower. Wind or pollinators carry the pollen from the male anthers to the female flower parts. After the pollen lands on the stigma, a pollen tube forms, and male reproductive material travels down the style and into the ovary, where it fertilizes an ovule.
Answer:
Fertilization occurs when one of the sperm cells fuses with the egg inside of an ovule. It occurs in ovary of female flower
Explanation:
After pollen grains land on the stigma, a pollen tube grows from the pollen grain, through the style, and into the ovary. Sperm cells inside the pollen grain travel down the pollen tube and into the ovary which contains the ovules.

3. Which feature is commonly formed
at a plate boundary where oceanic
crust converges with continental crust?
(1) a mid ocean ridge (2) an ocean trench (3) a transform fault (4) new oceanic crust
Answers
Answer:
2) an ocean trench
Explanation:
Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.
What is Ocean Trench?Long, narrow depressions on the seafloor are known as ocean trenches. These chasms are among the deepest natural places on Earth and the deepest portions of the ocean.
Every ocean basin on the planet has ocean trenches, but the deepest ones encircle the Pacific Ocean as part of the so-called "Ring of Fire," which is also home to active volcanoes and earthquake-prone regions. Tectonic activity, which refers to the movement of the Earth's lithosphere, is what causes ocean trenches.
Ocean trenches in particular are a characteristic of convergent plate borders, which occur where two or more tectonic plates collide. In a process known as subduction, dense lithosphere melts or slides beneath less dense lithosphere along numerous convergent plate borders, forming a trench.
Therefore, Ocean trench is a commonly formed at a plate boundary where oceanic crust converges with continental crust.

Why was it hard for scientists, non-scientists, and even Darwin to believe in the idea of evolution?
Answers
2. The text explains that selective breeding involves breeding animals or plants for
specific desirable traits. For example, humans bred different types of dogs to
accomplish certain jobs. Farmers breed chickens for having more meat and laying a
greater amount of eggs. Cattle are often selectively bred either for more meat or for
more milk production. The text also notes that breeding animals for size and strength
interferes with natural animal processes.
Based on this information presented in the text, who benefits from the traits different
animals are bred for?
A. humans breeding the animals
B. the animals being bred by the humans
C. both the humans breeding the animals and the animals being bred by the humans
D. animals not being bred by humans
Answers
Answer:
A. the humans breeding the animals
Explanation:
It says in there that it interferes with the natural animal processes so it probably doesn't help the animal, and it also said in there that we have breed for more desirable traits in other words we bred them to be more useful to us and give us benefits.

1. Consider the following food chain.
grass
deer
wolf
If the deer population increases, explain what could happen to the grass population
Answers
Most likely the grass population will decrease and the wolf population will increase.
Eventually it should level out again though.
If the population of deer will increase will result in the decrease in grass quantity.
What is a food chain?A food chain is a linear network of links in a food web that begins with producer organisms and ends with an predator, detritivores, or decomposer species.
A food chain also shows how organisms are related to one another through the food they consume. Each extent of a food chain represents a distinct trophic level.
Overgrazing occurs when there are too many deer in a given area, resulting in the loss of brush and shrubs in forested areas. The absence of undergrowth means that small animals and birds have no place to shelter and nest.
As a result, many native species are becoming extinct because they no longer have access to the habitat they require.
Thus, the grass population will decrease as a result of increase in deer population.
