<span>The importance of sexual reproduction in angiosperms is same as sexual reproduction of others organims that is to provide genetic variation. However, sexual reproduction of angiosperms also produce seed. Production of seed with fruit is what specific to angiosperm this phylum. so you can find some points regard the advantanges of producing seeds in angiosperms. This can used as addition point.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Answer:
Explanation:
If however, the data does not support the hypothesis or refutes it, then the hypothesis is in trouble, and we have to come up with a different hypothesis to explain the observations. If a large body of data supports the hypothesis, then it becomes a theory.
Answer:
There is no image showing the shape of an enzyme, however, the question can still be answered based on basic understanding. The answers are;
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding
Explanation:
An enzyme is a biological catalyst that regulates the rate of chemical reactions in living systems. Enzymes are proteinous in nature and every protein is made up of an amino acid sequence. The amino acid sequence forms a three-dimensional shape that determines the functionality of the enzyme.
Enzymes catalyze reactions by binding to their substrates in a lock and key pattern. This makes enzymes substrate-specific. If the enzyme's normal shape changes, the following will occur:
- Less binding of substrate
- won't follow the lock-and-key pattern of enzyme binding.
The right option is; dark-field microscope
A light microscope that makes the specimen appear light on a dark background is called a dark field microscope.
Dark field microscopes are light microscopes that are used in different ways to clearly view various specimens that are unstained, transparent, and hard to see using a light field unit. Dark field microscopes are very effective because they show the details of unstained and live samples. It is also very simple to use, and inexpensive to set up.
