Which choice is involved in both sexual and asexual reproduction?
seeds
sperm
spores
eggs
Answer:
it's going to be spern man
The choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.
What is the advantage of sexual reproduction over asexual reproduction?Both types of reproduction have advantages, for example, if a mutation occurs and becomes genetic, the chance of getting the disease is lower in sexual reproduction than in asexual reproduction. The possibility of recombination and crossing over reduces the rate of genetic disorders in sexual reproduction, whereas in asexual reproduction, the mutation passes from one to the other.
Hence, the choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

Which piece of evidence did Alfred Wegener's original theory of continental drift have access to?
A.) reversing paleomagnetism in rocks on the ocean floor
B.) seafloor spreading at mid-ocean ridges
C.) a seafloor that was geologically active with earthquakes, volcanoes, and mountain chains
D.) mountains in North America appearing to match up with mountains in Northern Europe
The piece of evidence that Alfred Wegener's original theory of continental drift has access to is the mountains in North America appearing to match up with mountains in Northern Europe. Thus, the correct option for this question is D.
What is Continental drift?Continental drift may be defined as a type of hypothesis that represents a gradual movement of the Earth's continents over geologic time relative to each other. This movement of the Earth's continents results from the motion of tectonic plates.
According to Alfred Wegener's original theory of continental drift, the continents of the Earth have been adjoined together and have migrated away from each other at different times in the history of the Earth.
This reflects that mountains in the continent of North America appear to match up with the mountains in the continent of Northern Europe.
Therefore, the correct option for this question is D.

Climate change is the website which most likely provides reliable information about climate change. Thus, the correct option is C.
What is Climate change?Climate change refers to the long-term change in temperatures and weather patterns of the area. These changes in temperature may be natural, however since the 1800s, human activities have been the major driver of climate change, primarily due to the burning of fossil fuels like combustion of coal, oil, and gas, which produces heat-trapping gases that cause global warming.
The Intergovernmental Panel on Climate Change (IPCC) assesses the peer-reviewed literature on the climate change for every 5 to 6 years. Their assessment reports, which are also peer-reviewed, are a credible source of information for the climate change.
Therefore, the correct option is C.

Know the difference between replication and repetition
Answer:
Repetition is when a scientist does the same experiment a number of times; replication is when other scientists reproduce a scientist’s experiment. Repetition is when a scientist publishes in more than one scientific periodical; replication is when another scientist reproduces another scientist’s results.
Explanation:

Which system is responsible for providing structure and support?
skeletal
nervous
digestive
circulatory
Answer:
Skeletal
Explanation:
The skeletal system not only helps to provide movement and support but also serves as a storage area for calcium and inorganic salts and a source of blood cells. The adult human body has 206 bones in a variety of shapes and sizes.
Answer:
Skeletal system
Explanation:
Think about it, your bones are hard. This helps with structure and support of your body. Your nervous system deals with your brain so that isn't it. Your digestive system is your stomach and all that good stuff, but it's job is processing food! So that's not it either. Then, last but not least, your circulatory system deals with your heart and blood and stuff. So, while yes, all of these systems are important, your skeletal system is what keeps you upright lol Hope this helps! Good luck!
