Answer:
Explanation: In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth's surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
The fit of the continents; the dispersion of ancient fossils, rocks, as well as highlands; and the positions of ancient climatic zones were all evidence for continental drift.
What is Continental Drift Theory?Continental drift was a groundbreaking theory that explained how continents shift position on the Earth's surface.
Alfred Wegener, a geophysicist and meteorologist, proposed the theory in 1912, but it was rejected by mainstream science at the time.
Plate tectonics caused continental drift over millions of years. Plate tectonics also explained how plate movement causes volcanoes and earthquakes, as well as how continent collisions create massive mountain ranges.
Continental drift was demonstrated by the fit of the continents, the dispersion of ancient fossils, rocks, and highlands, and the positions of ancient climatic zones.
Thus, these are the evidences that support the Continental Drift Theory.

Explanation:
Which statement correctly describes what proteins, lipids, and glycogen have in common
Answer:
They are all used as primary energy sources during exercise. They are each stored in the liver to be used as a ready energy reserve. They each can be broken down to provide ATP to cells.
Answer:
The statement that correctly describes what proteins, lipids, and glycogen have in common is C. they each can be broken down to provide ATP to cells. Proteins, lipids, and glycogen all consist of a group of molecules, which means they can be broken down to these smallest items. ATP, or adenosine triphosphate, is a molecule that can be found in anything, and which we need for everything because it is a source of energy in living beings.

Thirty corn seedlings of equal size were randomly assigned to one of three treatment groups. At the beginning of the experiment, the plants in group I were dried and the mass was determined.
Answer:
The definition of the particular situation is outlined throughout the following section of the justification.
Explanation:
The query given seems to be incomplete. Please find the full issue attachment.
(a)
CO2 provides an inorganic component containing cellular mass. Throughout the atmosphere, plant species suck up CO2. Plants manufacture sugars throughout the mechanism of photosynthesis. Sugar is turned into glucose, cellulose as well as certain carbohydrates processed in cell walls. This raises the density of the plant. The process needs water, Carbon dioxide respectively.(b)
Sunlight is absorbed by chlorophyll as well as converted through chemical energy. The plant utilizes biochemical resources to synthesize sugars. The volume including its plant has risen due to the manufacture of sugars, respectively. For producing sugars, plants require light. The loss in mass has been caused by cellular respiration. There's this community of crops in the dark. They don't do photosynthesis, hence.Because to get power for something like the operations including its plant, individuals had to undergo respiration. So there is no photosynthesis, and therefore there is no sugar development. But instead to release energy, the sugar contained in the plant is eaten. And that's why the amount including its plants holding in darkness reduces.There are 3 steps given below for cellular respiration:
GlycolysisKreb's Cycle Electron Chain of TransportCellar respiration fills certain living things with energy.
⇒ [tex]C_6H_{12}O_6 + 6 O_2\rightarrow 6CO_2 + 6H_2O + (ATP) power.[/tex]
The generated CO2 has so far been delivered from the body including its plant. Therefore the plant mass was indeed decreased by this.

Early scientists were confused by the Euglena because they wanted to classify all living things as either plants or animals. Why do you think the scientists were confused?
Answer:
Euglena perform photosynthesis through the presence of chloroplasts in their cells, but they are also able to feed like animals by consuming and digesting organic material. They have features of both an autotroph(an organisms that produces its own food, such as plants) and a heterotroph (an organism that can not produce its own food and instead need to consume organic matter). Due to having features associated with both plants and animals, this would cause confusion to the scientists at the time who struggled to classify them as either plant or animal.

Jackson uses a battery operated toothbrush that is rechargeable. What happens when Jackson plugs his toothbrush into an electrical outlet to recharge it?
Answer:
Explanation:
The type of battery that Jackson's toothbrush is using is a secondary cell; this is because it can be recharged (meaning the electrochemical reactions taking place in the battery can be reversed). Batteries generally work in such a way that, while using it, electrons move from the anode of the battery to the cathode. In primary cells, this process continues until there are no electron to be transferred from the anode to the cathode and then the battery "dies" and is disposed. But in a secondary cell, just like the battery of Jackson's toothbrush, when the battery is been recharged, the electrons start moving from the cathode back to the anode; which makes electrons available again in the anode for use.

80S ribosomes and circular DNA
70S ribosomes and circular DNA
70S ribosomes only
circular DNA only
Answer:
B) 70S ribosomes and circular DNA
Explanation:
Remember: Mitochondria is found in the cytoplasm of almost all eukaryotic cells.
All prokaryotes have 70S ribosomes. Eukaryotes have 80S ribosomes, with some exceptions like mitochondria and chloroplast.
Circular DNA is DNA that forms a closed loop and carries genetic material. In both prokaryotes and eukaryotes, the chromosome represents circular DNA, although in eukaryotes, the chromosomes are more complex in structure.

Which of the following statements about enzyme functions is true
Which type of secretion has an extra cellular effect such as the digestion of food?
Identify and explain all of the nutritional requirements of plants.
Answer:
Key Points
Nutrients and water are absorbed through the plants root system.
Carbon dioxide is absorbed through the leaves.
From seedling to mature plant, there is a complex dynamic between plants and their environment (soil and atmosphere).
Key Terms
germinate: to sprout or produce buds
photosynthesis: the process by which plants and other photoautotrophs generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts
nutrient: a source of nourishment, such as food, that can be metabolized by an organism to give energy and build tissue
Explanation:
Plants are unique organisms that can absorb nutrients and water through their root system, as well as carbon dioxide from the atmosphere. Soil quality and climate are the major determinants of plant distribution and growth. The combination of soil nutrients, water, and carbon dioxide, along with sunlight, allows plants to grow. In order to develop into mature, fruit -bearing plants, many requirements must be met and events must be coordinated.

What is the approximate average yearly total snowfall gradient between locations A and B?
(1) 0.25 in/mi (2) 2.50 in/mi (3) 0.40 in/mi (4) 4.00 in/mi
Snowstorms that continue three hours or longer, have consistent wind speeds of at least 35 mph (about 56 km/h), and have visibility of less than a quarter mile are referred to be blizzards. Thus option C is correct.
What average yearly total snowfall gradient?The image demonstrates a snowfall gradient, or the variation in snowfall rates from one place to the next. Weather.com meteorologist Brian Donegan stated, “It may happen everywhere that gets snow showers and is fairly regular.”
For clouds and snow to form, there must be adequate moisture in the atmosphere. Snow cannot form if there is insufficient moisture. The atmosphere must continuously add moisture to the clouds in order for snow to continue to create and fall to the ground during heavier precipitation.
Therefore, 0.40 in/mi is the approximate average yearly total snowfall gradient between locations A and B.
