Answer:
The main features of the solar system:
The Sun is our nearest star.
The planets orbit the Sun.
The time taken to orbit the Sun increases with distance from the Sun.
Gravity keeps the planets in orbit around the Sun and the moons in orbit around their planets.
From the Sun, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. You might need to be able to recall this in the exam.
The planets go around the Sun in slightly squashed circular elliptical orbits.
Pluto is classified as a dwarf planet or planetoid. It has a highly elliptical or eccentric orbit.

Many years ago a scientist Group E plants that produce wrinkled peas the peas from the plants produce new plants that also produce wrinkled peas the scientist concluded that something in the para plan will be transmitted to the next generation this discovery is known as
Answer:
This discovery is known as heredity.
Explanation:
In the question above, we can see an example of heredity, which is the process where a trait is passed from an ascendant to a descendant. As seen above, the wrinkled seed is a characteristic that was passed on to a plant through its parent, the plant that gave rise to it. The characteristics passed by heredity are transmitted through the continuous transfer of genetic material, present in the DNA. Since the descendants have the DNA of their parents, it is possible that the characteristics are transmitted as the generations advance.

mantle
Explanation:
yea I'm pretty sure that's it
Answer:
The Mantle
Explanation:
The mantle is the layer located directly under the sima. It is the largest layer of the Earth, 1800 miles thick. The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavyweight. This flow is due to great temperature differences from the bottom to the top of the mantle. The movement of the mantle is the reason that the plates of the Earth move! The temperature of the mantle varies from 1600 degrees Fahrenheit at the top to about 4000 degrees Fahrenheit near the bottom!
Explain how silent mutations affect the structure and function of the protein
Answer:
Silent mutations do not affect protein function
Explanation:
A mutation is defined as any alteration in the genetic material of a cell of a living organism. Moreover, a silent mutation refers to any mutation that does not alter the phenotype of the cell/organism (they are evolutionary neutral mutations). Silent mutations are base substitutions that do not alter the amino acid sequence of the resulting protein, and therefore these mutations do not alter protein function.

How are food webs used to help explain ecosystem interactions?
Food webs used to help explain ecosystem interaction as the food web shows the flow of energy from one organism to another.
What is Food web?Food webs have been defined as important conceptual tools for delineating feeding relationships among species within a community, revealing species interactions and community structure, and understanding the dynamics of energy transfer in an ecosystem.
It is defined as a graphical representation of the natural interconnection of food chains and what-eats-what in an ecological community. Food web is also called consumer-resource system.
Example of Food web is Falcon eats snake, which has eaten frog, which has eaten grasshopper, which has eaten grass. A food web shows the many different pathways where plants and animals are connected

Despite the best efforts of scientists to create an all-encompassing system of names for relationships between organisms, some still fall in a grey area. Some species of wasp are known as "parasitoids" and not true parasites. These wasps kill caterpillars to reproduce but do not harm any other caterpillars until they need to reproduce again. Why aren't these wasps considered true parasites?
Answer:
Wasps only use the caterpillars when producing offspring which kills the caterpillars.
Explanation:
'True parasites' are generally defined as organisms which live off 'host' organisms of another species at the expense of that organism by harming them in some way. They do this in a variety of ways for different reasons, the most common ones being as a source of food or favorable living conditions. Their lives are almost always entirely dependent on their host. Conventional parasites also usually don't kill their hosts as it is in their best interest that their host stays alive for them to gain the most advantage from them.
Wasps do not fit the true definition of a parasite because:
1. They don't rely on living off the caterpillars to live normally. Wasps are able to find their own sources of food and live on their own without other species. It is only when reproducing that they use and harm the caterpillars.
2. This process kills the caterpillars as the wasp larvae eat them when they emerge and grow which is unconventional for parasites.
It is because of these exceptions that these wasps are classified as 'parasitoids' and not conventional parasites.
Note: Wasps like these have been introduced many times because of this symbiotic relationship they have to help control caterpillar populations.

what do we call the flight in bees whereby mating occurs and drones are killed after mating the queen?
Answer:
The next male honey bee to mate with the queen will remove the previous endophallus and eventually lose his own after ejaculation. Male honey bees are only able to mate seven to 10 times during a mating flight, and after mating, a drone dies quickly, as his abdomen rips open when his endophallus is removed

Which explains how interference is avoided between the signals that cordless phones receive and the signals that they broadcast?
Answer:
the signals have different frequency
Explanation:
The way that interference is avoided in these cases is that the signals have different frequency. Cell phone signals travel in a very specific wavelength, how often this wave repeats in a given span is called the frequency. By having these signals in different frequencies it prevents the signals from mixing with each other and instead allowing them to reach their destination intact. Otherwise, the signals would combine into a mess of uncomprehensible data, which is what we call interference.

D.anywhere its service broadcasts and it can receive a signal.

Answer:
A, B, and D
Explanation:
Red light is reflected by the material.
Green light is absorbed by the material.

Calculate the weight of an object of 2000 g on Earth. 5. Calculate the weight of an object of 0.5 kg on Earth. 6. Calculate the weight of an object of 500 g on Earth. 7. Calculate the weight of an object of 50 kg on the Moon (gravity of 1.6 m/s2) 8. Calculate the weight of an object of 50 kg on Mars (gravity of 3.7 m/s2)
Answer:
1. 294N
2. 294N
3. 19.6N
4. 19.6N
5. 4.9N
6. 4.9N
7. 80N
8. 185N
Explanation:
The weight of an object is the force that gravity is having over it, and we measure it in Neutowns (N), which equals Kg x m/s².
To find the weight of an object, we use the formula F= m x g.
F stands for force, m for the object's mass, and g for gravity, which is the force that attracts objects to Earth, and we measure it by the acceleration that an object has during free falling.
The Earth's gravity is 9.8 m/s²
1. We use the formula F=m x g
F= 30kg x 9.8 m/s²
F= 294 N
2. We have to convert the 30000g into kg to use the formula
30000÷1000= 30kg
30000g equals to 30Kg, so the object's mass (m) is 30Kg.
F= m X g
F= 30kg X 9.8 m/s²
F= 294 N
3. F= m X g
F= 2kg X 9.8 m/s²
F= 19.6 N
4.We have to convert the 2000g into Kg.
2000÷1000= 2Kg
The object's mass (m) is 2Kg.
F= m X g
F= 2kg X 9.8 m/s²
F= 19.6 N
5. F= m X g
F= 0.5 kg X 9.8 m/s²
F= 4.9 N
6.We have to convert 500g to Kg.
500g÷1000=0.5Kg
The object's mass (m) is 0.5 kg
F= m X g
F= 0.5 Kg X 9.8 m/s²
F= 4.9 N
7. The gravity on the moon is different from the one on Earth. In the formula, instead of 9.8 m/s² for the gravity (g), we use 1.6 m/s².
F= m X g
F= 50Kg X 1.6m/s²
F= 80N
8. The gravity (g) on Mars is 3.7 m/s², so we have to use it in the formula where it says g to find the object's weight on Mars
F= 50Kg X 3.7m/s²
F= 185 N
