A sperm cell and an egg cell fuse to form which structure?
zygote
zygote = a diploid cell resulting from the fusion of two haploid gametes; a fertilized ovum
NOT FETUS
Answer:
The correct answer is- Resistance
Explanation:
The ability of any organism in a population to tolerate a chemical like insecticide, pesticide or antibiotic which is designed to kill it or slow its reproduction is called resistance.
For example, the antibiotic resistance is seen in some bacteria like MRSA(Methicillin-resistant staphylococcus aureus). They gain this resistance because they have some variant traits in their genome which provide them resistance against these chemicals.
These individual are selected through natural selection when the environmental condition changes and become adverse. So the correct answer is resistance.
<u>Answer:</u>
<em>The interaction the cattle egret exhibits with the buffalo is commensalism.
</em>
<u>Explanation:</u>
<em>In the type of interaction called commensalism</em> between two organisms, one organism benefits from the other while the other <em>organism is neither benefited nor harmed. </em>
When the buffalo moves around a field grazing it disturbs the insects and they fly away from the buffalo and the cattle egret which keeps following the <em>grazing buffalo eats the insects.
</em>
The buffalo doesn’t benefit from this type of interaction. <em>A commensalism relation is a positive-neutral kind of relation.
</em>
Answer:
inputs: carbon dioxide, water
outputs: sugar, oxygen
Explanation:
Here is the equation for photosynthesis:
CO2 + H2O ----sunlight energy---> C6H12O6 (glucose/sugar) + O2
Answer:
The correct answer is e. Golgi apparatus
Explanation:
Golgi apparatus are also known as Golgi bodies and it bound by only a single membrane. It is present near the endoplasmic reticulum in the cell. Golgi apparatus is composed of 5-8 membrane-bound sac-like structures called cisternae.
The Golgi apparatus plays important role in the modification of molecules like proteins and lipids. The unprocessed proteins that are released from the endoplasmic reticulum enter the Golgi apparatus and in the Golgi apparatus its modification like glycosylation and phosphorylation occurs.
Then these processed proteins are released outside from the Golgi in vesicle forms which have a signal molecule that guides it to various locations in the cell or towards the plasma membrane from where it can move out of the cell.
Therefore the correct answer is e. Golgi apparatus.
