After fertilisation of plants
occurs between the male gamete and the egg cell, the zygote produced undergoes mitosis forming two cells. explain.
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). The zygote stage is followed by cleavage when a cell gets subdivided into further smaller cells.
Explanation:
Fertilization is defined as the fusion of the male gamete (sperm) and the female gamete (egg cell) in plants that develops into a zygote. After fertilization, a series of events occurs in the zygote to develop into a seed.
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). The zygote stage is followed by cleavage when a cell gets subdivided into further smaller cells.

In the Galapagos Islands, there were many species of tortoises, woodpeckers and other animals. Why were the animals like the tortoises so different in appearances, when they lived on neighbor islands?
Answer:
The animals were different because there were things the animals need to adapt to in the Galapagos that may have changed their appearance. for example a bird may have a different shaped beak because they started to evolve so they could eat foods that were available to them on the island

Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the
male minnows all had a moderate number of spots
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were
better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female
minnows in this pond preferred to mate with males that had the most spots,
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
Answer:
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.

which type of traits are responsible for evolution?
Answer:
In biology, evolution is the change in the inherited traits of a population from generation to generation. These traits are the expression of genes that are copied and passed on to offspring during reproduction. ... Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce.
Heredity - This is the passing on of traits from parents to their offspring either through sexual reproduction or asexual reproduction.

What is Water Pollution?Water Pollution is the contamination of the water bodies by human activities causing water unusable for drinking, cooking, etc. It contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and making toxic to humans or the environment.
Types of Water Pollution
1. Groundwater pollution
2. Surface water Pollution
3. Ocean water pollution
4. Point source pollution
5. Non-point source
It is mainly caused by
1. Industrial waste
2. Oils leak and spills
3. Global warming
4. Agriculture
It can be controlled by not using chemical fertilizers in the agricultural field, use the minimum amount of detergents or bleach near water bodies.
So, there are three methods of point pollution control are
1. To use less toxic or non-toxic chemicals
2. To use public transport and avoid personal vehicle
3. Say no to plastic bags

Following a volcanic eruption, which event is usually the last one to be
observed?
A. Grasses begin to grow in soil with organic matter
B. Lichens begin to cover bare rock.
C. Mosses begin to grow in thin, rocky soil.
D. Trees begin to grow in thick, rich soil.
Answer:
Hello There!!
Explanation:
The answer is=>A. Grasses begin to grow in soil with organic matter.
hope this helps, have a great day!!
~Pinky~
Answer: I do know the answer, I always use the Study Guide, which is incredibly helpful, I will share both my notes, and answer, which is D. Trees begin to grow in thick, rich soil.
Explanation: After a volcanic eruption, a process known as a Ecological Succession happens. Resulting in, lichens, which is the first living species to grow on the rocks. Afterwards, mosses and small annual plants are the second species, these species begin to grow in soil made by the lichens, since after the eruption the lichens release acid that helps break the rock into soil, then the mosses and annual plants reproduce by the help of the wind, and use the soil formed by the previous species. Furthermore, grasses and other long living plants begin to grow in the richer soil. Then, grasses, shrubs, and intolerance trees, such as pine form. Until, the last observed, which is shade-tolerant trees, such as oak and hickory! Have a good day, you’re welcome. P.s. Provided a picture from my source! And the Quiz as I have the same one, if I can! ♡︎
