Answer:
different horse species could be alive at the same time as others. they all descended from a common ancestor.
Answer: The reason why an evolutionary diagram looks more like a bush than a straight line is the development of new species.
To be more clear - initially we can have one species, and that species will over time start to live in multiple different environments. As the species starts to adapt to the new environment, its appearance and genetics are gradually changing in order for it to have more advantageous traits to survive in the environment. As the time passes, the changes that will emerge in some members will create a new species, and that process will constantly go on, until extinction that is. So we have one species that is an ancestor of multiple new species, thus the family tree, or rather evolutionary diagram, starts to branch out, and as the time passes, it will branch out more and more and take a bush-like looks.

How would the genome of a sexual reproducing multicellular organism be different from the genome of an asexual reproducing unicellular organisms
The genome of an erotic reproducing multicellular organism is different from the genome of an agamous reproducing unicellular organism in various aspects.
What do you mean by Genome?A genome may be defined as an organism's complete set of genetic instructions. It is a complete set of DNA in any organism.
The genome of unicellular organisms is genetically identical to one another, while a high diversity is seen in the case of the erotic reproducing multicellular organism due to the phenomenon of variations. The genome of a unicellular organism is very simple, while it is very complex in the erotic reproducing multicellular organism.
Therefore, the genome of an erotic reproducing multicellular organism is different from the genome of an agamous reproducing unicellular organism in various aspects.

By comparing the position of the sun and the shadows cast at noon on the summer solstice in two different cities, Eratosthenes was the first to determine that Earth was round. the distance between the two cities. the distance from Earth to the sun. the size of Earth.
Answer: The correct statement is ' the Size of the Earth'.
Explanation:
Most Greek scholars soo many years agreed that the earth was shperical in shape but never knew the size of the Earth.
Eratosthenes was a man of many talents, he was a geographer, a mathematician, an astronomer and a historian. With the expanse of knowledge he had, he compared the position of the sun and the shadows cast at noon on the summer solstice in two different cities. With reasonable accuracy, he was able to determine the shperical size of the earth. He computed this by using simple geometry and trigonometry and by recognizing Earth as a sphere in space.
Which phrase describes an irregular galaxy?

contains many young stars
has arms that extend from the center
is larger than other types of galaxies
Answer:
"Contains many young stars".
Explanation:
The phrase that describes an irregular galaxy is "contains many young stars". The correct option is B.
What is a galaxy?A galaxy is a collection of stars, stellar remains, interstellar gas, dust, and dark matter that are gravitationally bonded together.
A galaxy is a vast collection of stars, solar systems, gas, and dust. Gravity holds a galaxy together. A supermassive black hole also resides in the centre of our galaxy, the Milky Way.
In contrast to spiral or elliptical galaxies, irregular galaxies lack a recognizable regular shape.
Regular Hubble sequence classes do not apply to irregular galaxies, which typically have a chaotic appearance, no nuclear bulge, and no sign of spiral arm structure.
Thus, the correct option is B.

Carbon (C)
Atomic #: 6
Atomic Mass: 12
Question: Calculate the number of electrons using the information given. Write the number on the line and then draw the electrons into the Bohr model.
Assuming the atom has a neutral charge, the number of electrons will be the same as the number of protons. The number of protons is given by the atomic number, 6, so there are six electrons.
The first "ring" of the atom (closest to the center) can take two electrons, so draw two electrons there. The second (outer) "ring" of the atom can take the remaining electrons, so draw four electrons there.
Atomic mass is irrelevant in this specific problem.

embryo.
b. Producing gametes (sperm and egg cells) that
unite inside the female reproductive system.
c. Removing nitrogenous wastes and excess water
from the blood.
d. Producing gametes (sperm and egg cells) that
unite inside the male reproductive system.
Answer:
b. Producing gametes (sperm and egg cells) that unite inside the female reproductive system.
Explanation:
The "gametes" refer to the sex cells in humans. The female sex cells are called "egg cells" and these are being produced by the ovary. The male sex cells are called "sperm cells" and these are being produced by the testicles. After copulation, there's a probability for the egg cells and sperm cells to unite. They unite inside the female's reproductive system, specifically inside the "fallopian tube."

An adaptation is any inherited mechanism that makes an organism better able to survive in the changing environment.
It can be structural, behavioral features which help organism to survive.
Example is a hawk's feet and sharp claws are types of adaptations help it to hunt and capture mice.
Another adaptation is habitat where organisms having a specific habitat adapt different features.
Bird beak adaptations is the best example where they use their beaks for acquiring meals, consuming, help in climbing, and protection.
Bird beaks adapted enough to assist them to discover specific meals inside their habitat.
Birds have adapted feathers which make them flight simpler like Long feathers and tail of birds provide them steadiness and insulation.

-Rotating crops between different fields
-Planting crops in contour strips
-Using shelterbelts to separate crop fields
-Switching from chemical to organic fertilizers
Answer:
planting crops in conotur strips, i just did the assigned reading and it literally says the answer. the other person is wrong
Explanation:
Planting crops in contour strips would be the most helpful strategy for protecting the soil from wind erosion.
• A system of alternating strips of small grains or meadow with strips of row crops on the contour is known as contour stripping.
• The method of contour stripping could minimize soil erosion by up to 75 percent in comparison to planting row crops down and up the slope.
• The strip cropping differentiates fields into narrow, long sections, which assists in monitoring erosion and runoff while growing crops in rotation.
• Contour stripping helps to conserve rainwater and minimize soil erosion.
Thus, the correct statement is planting crops in contour strips.
