What does it mean to be a "pioneer"? Using your explanation, what do you think it means if something is a "pioneer species"?
Answer:
to be one of the first people to do something:
a person who is among the first to study or develop something
Explanation:
Pioneer species are hardy species which are the first to colonize barren environments or previously biodiverse steady-state ecosystems that have been disrupted, such as by fire.[1] Some lichens grow on rocks without soil, so may be among the first of life forms, and break down the rocks into soil for plants
Why would we not have animals without plants?
try to create an original enough answer! ^^ Thank you!
Answer: Humans and animals use the oxygen (O2) in the air for their energy process and produce CO2 as waste. A plant does the exact opposite. ... If there were no plants on the planet we wouldn't be able to breathe. Humans in particular, however, also produce other waste

- What is the geocentric model of the
universe?
a) The Theory of Evolution
b) Newton's Laws of Motion
c) The belief that Earth is at the center of our solar system
d) Superstition
Answer:
I believe C,
Explanation:
The geocentric model of the universe maintained that the Earth was at the center of everything in the solar system. In it, the Sun and planets orbited around our planet. Many odd and elaborate adaptations were required to make this model agree with observations. This problem increased, as our our observations got more accurate.
The geocentric model was superseded by the heliocentric model, in which the planets all orbited the Sun. The Heliocentric model was eventually able to show that the positions of the planets over time were much more convincingly, and simply portrayed by it, than by the former model.
Apologizes if I'm wrong/
Answer: It is c because the person who made it or thought of it said that the earth is at center of the cosmos or the universe.

What are chromosomes? When do chromosomes form?
Answer:
Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

What do you think will happen when you breed two green-and-pink spotted aliens?
Answer:
They will have a green-and-pink spotted alien most likely.
Explanation:
Since a dominant gene is the gene that we see represented in the physical appearance of an animal or human, we can only estimate that green-and-pink spots are the dominate gene because both aliens have them. Our best guess is that the two green-and-pink spotted aliens will breed a green-and-pink spotted baby alien. However, this is not 100% full proof.
Hope this helps!
Answer:
Born aliens may be with green spots, or with pink spots or with both colors of spots.

a given gene sequence contains 49 adenine base pairs. how many thymine bases will be included in the RNA strand?
a. 49
b. 98
c. 24
d. 0
Answer:
b
Explanation:
If there are 49 pairs you would have to multiply it by 2 to get your original number.
The fundamental and functional elements of genetics are called genes. it is composed of thread-like DNA structures found in the coiled form. Genes direct the formation of the proteins required for cellular activities.
0 thymine bases will be included in the RNA strand.
How to know the number of nucleotide bases?In a DNA or RNA molecule, the number of nucleotide bases is given by Chargaff's rule. Nucleotide bases are the structures of the purine and the pyrimidine rings.According to the base-pairing rule, an adenine base will always pair with thymine in DNA and uracil in the RNA molecule similarly the guanine will bond with the cytosine in the DNA or RNA molecules and vice versa.As the RNA molecule does not have thymine but codes for uracil will not base pair with the complementary adenine base.Therefore, option d. 0 thymine will be included in the RNA strand.

whats stigma in a plant
[tex]\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}[/tex]
The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules. The male parts are called stamens and usually surround the pistil.
In a flower, this landing zone and entrance is the stigma. It plays a pivotal role in reproduction. Most stigmas are adapted to trap pollen with hairs, flaps and other surfaces to increase their efficiency. Most stigmas are covered with a waxy, sticky substance.
Answer:
Stigma: The part of the pistil where pollen germinates.

what is the relationship between a protein the cell and DNA?
a. DNA is produced by protein which is produced in the cell
b. dna controls the production of protein in the cell
c. protein is composed of DNA which is produced in the cell
d. a cell is composed of DNA and protein
Answer:
Cells contain DNA that controls the production of proteins. (2) DNA is composed of proteins that carry coded information for how cells function. (3) Proteins are used to produce cells that link amino acids together into DNA. (4) Cells are linked together by proteins to make different kinds of DNA molecules.

Scientists have observed that new crust, such as mid-ocean ridges, is formed where two plates are moving away from each other. Based on this observation and the data on the maps, where do you suspect that old crust is destroyed and recycled? Provide three specific locations on the map where you think this process is occurring
Answer:
Old crust is destroyed at boundaries where two plates are moving toward each other, or converging. Specific examples include the Australian and Pacific plates, the Caribbean and Cocos plates, and the southwest corner of the North American plate and the Pacific plate.

where do all of the cells in the human body come from
Answer:
Every cell in the body originates from a single fertilized egg called a zygote. The zygote divides repeatedly to produce an embryo. These embryonic cells continue to divide, differentiating into all the cell types present in the body of all humans (and other mammals), from a new-born baby to an elderly adult
Answer:
The zygote
Explanation:
I'm not exactly sure what you're talking about, but this is what I found: "Every cell in the body originates from a single fertilized egg called a zygote.

What conclusion can be drawn from the diagram to support the theory of evolution?
Man evolved from gorillas which evolved from chimpanzees.
Gibbons are most closely related to man because of similarities in their skeletal structure.
Orangutans have a larger jaw size than chimpanzees, allowing them to have a more carnivorous diet.
Gorillas continued to walk on all four limbs to move around on the floor of forests, while man became bipedal to live in grasslands in order to hunt and carry food.
Answer:
Following conclusion could be drawn from the given diagram;
Gorillas continued to walk on all four limbs to move around on the floor of forests, while man became bipedal to live in grasslands in order to hunt and carry food.
Gorillas continued to walk on all four limbs to move around on the floor of forests, while man became bipedal to live in grasslands in order to hunt and carry food.
What is theory of evolution?The theory of evolution is a scientific explanation for the diversity of life on Earth. It explains how species of organisms change over time through the processes of natural selection, genetic variation, and inheritance.
The theory of evolution is supported by evidence from many different areas of science, including genetics, geology, comparative anatomy, and biogeography. The theory proposes that all species, both past and present, are related through a common ancestry and have evolved over millions of years through a process of gradual change and adaptation. It is considered one of the most fundamental and well-supported scientific theories in biology.
