Explanation:
:3
The bones in cats' legs that help them walk are extremely similar to the bones in whales' flippers that help them swim. It exemplifies homologous structures.
What are homologous structures?These are similar in structure and location but perform different functions. They result in divergent evolution.
What are analogous structures?These are similar in function but have different origin and structures. They result in convergent evolution.
What are vestigial structures?These structures do not perform any function and are present in a residual form in the body
What is endosymbiosis?It is a kind of relationship in which one organism resides inside the body of the other organism.

Explanation:
In beta fish, a blue tail (B) is dominant over a black tail (b) and a metallic sheen (M) is dominant
over no metallic sheen (m). A female beta fish who is heterozygous for blue tail with no metallic
sheen has offspring with a male who has a black tail and has no metallic sheen. What is the
phenotypic ratio of their offspring?
Answer:
D) 8 blue tail nonmetallic: 8 black tail nonmetallic
Explanation:
The first thing to realize about the problem is that all offspring will be nonmetallic. Both parents are pure recessive for nonmetallic tails; therefore, their offspring cannot have metallic tails. So to find the ratio, use a simple punnet square with Bb and bb. This results in a 50% chance of Bb (blue) and 50% bb (black). So the last answer is correct.

A
Option 1
B
Option 2
с
Option 3
D
Option 4
No
Answer:
The correct answer would be option 4
The interactions are dependent on the plant's ability to respond to the direction of light Photosynthesis.
What is Photosynthesis?Photosynthesis is essential to most life on Earth. Plants, algae, and some types of bacteria carry out the process by capturing solar energy to create oxygen (O2) and chemical energy stored in glucose (a sugar).
Consequently, herbivores get this energy from consuming plants, and carnivores get it from eating herbivores.
Plants absorb water (H2O) and carbon dioxide (CO2) from the soil and atmosphere during photosynthesis. Water is oxidized, which means it loses electrons, while carbon dioxide is reduced, which means it receives electrons, inside the plant cell.
Therefore, The interactions are dependent on the plant's ability to respond to the direction of light Photosynthesis.

Which is a difference between plant and animal cells?
A) An animal cell can produce energy, because if has mitochondria.
B) A plant cell has a well defined shape, because it has a cell wall.
C) A plant cell can store genetic information, because it has a nucleus.
D) Molecules can only pass into an animal cell because it has a cell membrane.
Answer:
B. A plant cell has a well defined shape because it has a cell wall
Explanation:
When you compare an animal cell to a plant cell you can see that a plant cell has a cell wall while and animal cell only has a cell memebrane. The cell walls of the plant help the plant by providing support and keeping it's shape.
The difference between plant and animal cells is plant cell has a well defined shape, because it has a cell wall.
What are the functions of cell wall?The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress.
The main functions of the cell wall are to provide structure, support, and protection for the cell. The cell wall in plants is composed mainly of cellulose and contains three layers in many plants.
The cell wall is composed of a network of cellulose microfibrils and cross-linking glycans embedded in a highly cross-linked matrix of pectin polysaccharides.

Three specific anatomical structures that make monkeys special or at least different and successful in its natural environment.
Answer:
Monkeys unlike most mammals (besides humans) have imposable thumbs which helps them to climb trees and open nuts and fruits.
Monkeys also have powerful tails which they use to hang on branches and to assist them in balance.
Along with imposable thumbs and strong tails, monkeys have long and flexible legs and arms which makes it easy for them to get around and climb trees.

Which of the following sources of electricity DOES NOT employ the use of turbines?
A
Solar
B
Wind
C. Hydro
D.
Fossil Fuels
=========================================================
Explanation:
The sources of wind, hydro, and fossil fuels all use a turbine. So we can rule out choices B,C, and D.
A turbine is basically a wheel that spins to generate motion energy into electrical energy. Think of it like one of those stationary bicycles and the bike powers up a nearby lamp (the faster you pedal, the brighter the bulb gets). Another example that's similar to a turbine would be those flashlights where you can rotate a crank to have the light come on (which is useful for when the batteries are completely dead). The windmill blades act as a giant turbine that the wind spins around. Hydroelectric turbines are spun by the falling water. Fossil fuels are burned to create very hot steam which then powers a turbine. Even nuclear power uses turbines as well. With fossil fuels and nuclear energy, the idea is to heat up a vat of water and then turn that intensely hot steam into electrical energy through a turbine.
With solar panels however, the electrical energy is converted through a process of sunlight interacting with the solar cells that doesn't require a turbine. This explains why you can use solar panels to power up devices such as phones or laptops without having any moving parts. All you need is a flat set of solar panels.
There is a slight variation of solar power known as "concentrated solar power", aka "concentrated solar thermal", where solar panels are not used. Instead, a vast array of mirrors are set up to aim the suns rays at a very specific narrow area. Think of it like a magnifying glass to focus the suns rays. The place where the narrow beam hits has a very high temperature. This high temperature heats up water to turn to steam, and the process from here is effectively the same as fossil fuels or nuclear energy. So that means turbines are involved with concentrated solar power. I'm assuming your teacher is specifically referring to solar panels when they mentioned choice A.

Sexual and asexual reproduction allow for transfer of genetic material to offspring. Which
of the following is true regarding how asexual reproduction differs from sexual
reproduction?
1.Asexual reproduction is for changing environments, sexual reproduction is for stable
environments
2.Asexual reproduction produces genetically identical offspring; sexual reproduction
produces genetically different offspring.
3.Meiosis is a form of asexual reproduction; mitosis is a form of sexual reproduction
4.Asexual reproduction is for plants; sexual reproduction is for animals,
answer: asexual reproduction produces genetically identical offspring; sexual reproduction produces genetically different offspring
explanation:
asexual reproduction is when a single organism uses its own DNA as a template to create another organism (through binary fission, fragmentation, budding, etc.) that is genetically identical
sexual reproduction is when two organisms create a combination of DNA (through a mixing of genes during meiosis, reproduction, etc.) to create an organism that is genetically different
How do scientists learn about the age of the solar system and its planetary bodies? Select the two correct answers.
a. comparing the composition of the gaseous planets to the rocky planets
b. using radiometric dating of meteorites
c. measuring distances between planets
d. analyzing impact craters on planetary body surfaces
Answer: B, C
Explanation: Scientists use radiometric dating of meteorites and analyze the impact craters on planetary body surfaces to learn about the age of the solar system and its planetary bodies.
Using radiometric dating of meteorites and analyzing impact craters on planetary body surfaces are the two methods that tells us about the age of solar system.
The age of solar system and its planetary bodies can be find out by using radioactive dating techniques. Scientists have find out that the Solar System is 4.6 billion years old due to this technique. The other way to find out the age of solar system and its planetary bodies by counting the number of impact craters occurs on planetary body surfaces so these two methods provides information about the age of solar system and its planetary bodies
