Answer:
The correct answer would be d chloroplasts, which can be found in leaf cells of trees.
Chloroplasts are double-membrane cell organelle usually present in leaf cells of a plant.
They are the site of photosynthesis in plants by which plants convert solar energy into sugars. Oxygen is released as the byproduct of the process.
Light reaction of the photosynthesis takes place in the thylakoid membrane. It produces ATP and NADPH and releases oxygen.
Dark reaction takes place in the stroma of the chloroplast in which ATP and NADPH are used to fix carbon (obtained from carbon dioxide) into sugars (glucose).
The overall reaction is:
6CO₂ + 6H₂O + solar energy → C₆H₁₂O₆ + 6O₂
How do rivers become larger as they travel across land?
Tributaries combine, adding water to rivers.
A tributary is a stream that flows into a larger river. Small streams from around an area combine together to form a bigger tributary that eventually falls into rivers. This adds water to the main river, finally leading this river water out into an ocean.
Answer:
The correct answer is option a. "by trophallaxis with receiver bee".
Explanation:
Bees collect nectar from flowering plants, and when nectar foragers return to their colonies, they unload the nectar by trophallaxis with receiver bee. Trophallaxis is defined as the interchange of regurgitated liquids between insects, this is the process that occurs between the foragers and the receiver bees once they give the collected nectar to the hive.
C. Lysosomes, otherwise known as the suicide sac, digests other molecules. It’s known as the suicide sac because if it digests too much in an attempt to clean the cell, it will explode.
<span>A frequency graph can represent selection to illustrate population variation.
Frequency graphs are used to represent data to identify a range of measure. It displays a visual illustration that presents frequency counts to make the information be interpreted more easily. It also shows an absolute distribution or relative frequencies like precentages or proportions. Frequency table or Frequency graph is the simplest method to show the number of occurrences of a particular characteristics. Histograms or bar charts are both displays of frequencies. This is done through plotting columns on a graph. It is usually written thru an X and Y axis which generally represents a measured variable and frequency count, respectively.</span>
