Use Darwin's theory of Natural Selection to explain the process by which the four-legged land animal, A, may have evolved, over about 20 million years, from the fish-like creature, C, in the swampy conditions of the time.
Answer:
Due to environmental conditions.
Explanation:
With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.

8. The diagram below shows the shift in the spectrum for hydrogen light from several different sources in the universe.
What is the best argument that can be made from this data?
More distant galaxies are moving toward us faster.
More distant galaxies are brighter.
More distant galaxies are not as bright.
More distant galaxies are moving away faster.
Answer:
more distant galaxies are moving away faster.
the shift towards red (Doppler effect like with sound on Earth) is the indication.
Explanation:
what did this have to do with biology ?
and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...
Sasha uses a basketball and a tennis ball to represent two astronomical bodies based on their sizes.
Which of the following representations is the most correct based on what Sasha has? (5 points)
a
The basketball represents Earth and the tennis ball represents the solar system.
b
The basketball represents the moon and the tennis ball represents the solar system.
c
The basketball represents the solar system and the tennis ball represents Earth.
d
The basketball represents the solar system and the tennis ball represents the Milky Way.
Answer:
I believe the answer is C.
Explanation:
This is because the basketball is the bigger object here so that should represent something bigger like the solar system. Then the tennis ball would represent earth because it is the smaller object here.

Why do boys tend to get so nervous when they talk to a girl and what does that mean??
What does it mean when a guy looks at you at random points throughout the day??
Answer:
1. It's because when they talk to girls (Not all), they fill their head with all sorts of doubts and worries and then feels nervous as a result.. like for example they could be thinking "Am I making the right impression? Am I too annoying? What does she think of me?"
2. It means that they think that person is pretty. But if it gets too weird or annoying, you should report/tell an adult about it right away.

Answer:
I don't know your reasons on how you would feel about becoming an astrobiologist but this is what I found and my feelings.
Explanation:
The Perseverance twin is called Optimism. This has all of the same electronics as Perseverance and it’s important to have a twin so that they can test things before they operate Perseverance. When they do land on Mars they need the twin to test out all of the sequences and plan that they have for the rover before they send them up to Perseverance on the surface of Mars. Also, if they have a problem with Perseverance it gives them a place to practice how they recover from that problem.
Personally, for me, I would not like to become an astrobiologist. I like science but not that much. I like the simple questions of why and how does it work. I’m not entirely sure that we as humans are meant to be on any other planet except earth. Earth has been here for many many years and seems to reset itself. I don’t care why and will never know why in my lifetime. I’s just not something that I like to considerate doing as a career.
NASA is targeting no earlier than April 8 for the Ingenuity Mars Helicopter to make the first attempt at powered, controlled flight of an aircraft on another planet. Before the 4-pound (1.8-kilogram) rotorcraft can attempt its first flight, however, both it and its team must meet a series of daunting milestones.
Ingenuity remains attached to the belly of NASA’s Perseverance rover, which touched down on Mars Feb. 18. On March 21, the rover deployed the guitar case-shaped graphite composite debris shield that protected Ingenuity during landing. Ingenuity is battery powered and completely sef recharging from the solar panel on the top. The rover currently is in transit to the “airfield” where Ingenuity will attempt to fly. Once deployed, Ingenuity will have 30 Martian days, or sols, (31 Earth days) to conduct its test flight campaign. All data and pictures will be transmitted to Perseverance and then uploaded for all to see.
The offspring in binary fission are
identical
different
Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.

Explain why DNA Sequencing proves that all species have a common ancestor
Answer:
Below
Explanation:
The reason why we can conclude that all species have common ancerstory is that all the species have several same base pairs. Here are a few listed:
A-G-G-C
As well as this later on:
C-C-A-A-C-C
Because this strand of DNA has several common base pairs, we can conldude that the species have common ancestory that made it this way.
Hope this helps!
Fur seals and sea lions have similar anatomy. They probably have a common ancestor.

Into what kingdom would each of the following be classified:a. Unicellular prokaryotes that live in dust. _______________________[Text Wrapping Break] b. Unicellular eukaryotes that line in pond water. _____________________[Text Wrapping Break] c. Multicellular eukaryotes that live all over the planet and consume food. ______________________ [Text Wrapping Break] d. Unicellular prokaryotes that live in volcanic ash. __________________________[Text Wrapping Break] e. Multicellular eukaryotes that have cell walls and are heterotrophic. _______________________[Text Wrapping Break] f. Multicellular eukaryotes that have cell walls and are autotrophic. ________________________
Answer:
A. Unicellular prokaryotes that live in dust. Monera.
B. Unicellular eukaryotes that line in pond water. Protist.
C. Multicellular eukaryotes that live all over the planet and consume food. Animals.
D. Unicellular prokaryotes that live in volcanic ash. Monera.
E. Multicellular eukaryotes that have cell walls and are heterotrophic. Fungi.
F. Multicellular eukaryotes that have cell walls and are autotrophic. Plants.
Explanation:
The 5 kingdoms are a way of classifying all living organisms on our planet, as each species inside a kingdom shares similarities with the other species in it.
Monera kingdom includes all of the prokaryotic organisms that exist, which includes bacteria and archaea. These beings are characterized by lacking a nucleus and membrane-bound organelles and having one single circular chromosome that is found in the center of the cell. They are unicellular. Example: escherichia coli.
Protists are the most primitive eukaryotes that exist, most of them are unicellular and microscopic, but possess a nucleus and specialized organelles like the rest of the eukaryotes have. Example: yeasts.
Fungi and Plants are quite similar, they are multicellular eukaryotes that have cell walls. Their main difference relies on the way they obtain nutrients: fungi are heterotrophs, they feed off living things; plants, however, are autotrophs and realize photosynthesis (they do not need to feed). Fungi and Plants also reproduce differently: fungi reproduce through spores; plants can reproduce sexually or asexually. Fungi example: amanita; plant example: cactus.
Animals are multicellular eukaryotic organisms that reproduce sexually and are heterotrophs (some feed off plants, some feed off other animals). They are characterized by their ability to move. Example: horse.

Differentiation of cells has an important role in the cell division of complex organisms. What would happen without this differentiation of cells?
Explanation:
sana po nakatulong sainyo thanks❤
Cells are the basis of the survival of human beings. We, the living organisms are made up of cells. If cells won’t divide no new organisms would originate.
What is cell division?
Cell division is the process by which a parent cell divides, when a mother cell divides into two or more daughter cells. Cell division usually occurs as part of a larger cell cycle. Mitosis is a process of nuclear division in eukaryotic cells that occurs when a parent cell divides to produce two identical daughter cells. During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus.
The existing cells will die and no new cells will be produced as there is no cell division.
