An adaptation in the stigma that helps with fertilization is the ability of pollen grains to germinate on this structure. It allows plants to reproduce.
What is an adaptation?
An adaptation can be defined as a type of trait that allows organisms to survive and reproduce in particular conditions.
Adaptation favors the process of natural selection, which involves differential survival and reproduction.
Moreover, stigma is a plant structure that receives pollen grains (male gametes) during fertilization.

Why does the DNA move through the gel when an electrical current is generated?
Answer:
DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.
Explanation:
_____ plants are able to reduce photorespiration by creating a _____ concentration of _____ in bundle sheath cells where the calvin cycle occurs.
Answer:
C4,high, CO2Explanation:
Try again. Your carrying capacity line should be a horizontal flat line because it represents a
single number. It should intersect the y-axis at the highest population of bacteria the petri
dish can support.
Draw a line to estimate the carrying capacity of the petri dish. To draw a line, click two points
on the graph. Afterwards, drag and drop your two points to edit your line. The coordinates for the
two points will be shown in the table below the graph.

Based on your knowledge of protein synthesis and the information in the diagram,
summarize how enzymes are made. (3 points)
Explanation:
The chemical reactions involved in photosynthesis are controlled by enzymes . As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate.
Enzymes are biological catalysts - they speed up chemical reactions. The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.
Enzymes are required for most of the chemical reactions that occur in organisms. These reactions occur in the breakdown of chemical molecules, which we see in the digestive system.

What are Heterotrophs known as ?
Answer:
An organism that doesnt not produce its own food
Explanation:
Heterotrophs are consumers who eat other organisms for food, while autotrophs or producers make food by process of photosynthesis.
Answer:
A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”
Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.
Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. Each food chain consists of three trophic levels, which describe an organism’s role in an ecosystem. Occupying the first trophic level are autotrophs, such as plants and algae. Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level. Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs.
A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter. Detritivores play an important role in maintaining a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.

During apoptosis, which cellular organelle does the work of breaking up the nucleus and causing the cell to die?
ribosome
mitochondrion
lysosome
Golgi apparatus
Answer: Lysosomes
Explanation: Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

What are the outcomes for hares being introduced into the grassland ecosystem
Answer: The correct answers should be the hares will multiply indiscriminately and destroy the ecosystem and the native herbivores will experience increased competition for resources.
Since the hares wouldn't have predators, and they are famous for rapid breeding, they would overpopulate the ecosystem. On the other hand, the native animals would have to compete with this population of hares for food and would have less for for themselves.

How do you think a human egg is similar to a chicken egg? How are they different ?
Answer:
They both eventually lead to the birth of a chicken or human. And they start very similarly. They are very different, also, because instead of having a physical egg, humans have oval eggs that eventually make the baby, before birth. Chickens on the other hand give birth to the chick that is still inside the egg.
