The answer is <span>Conduct a test cross with a purebred recessive plant.
</span>
Test cross is the cross between an organism with unknown dominant genotype and an organism with known recessive genotype.
<span>Since dominant trait results from a dominant allele, the test cross can determine if an unknown genotype is heterozygous and homozygous dominant. </span>
If A is dominant allele, and a is recessive allele, then AA is dominant homozygote, Aa is a heterozygote, and aa is recessive homozygote.
<span>According to the Punnett square, if all of the offspring are heterozygote (Aa), then unknown genotype is dominant homozygous (AA). If half of the offspring are the heterozygote, and the other half are recessive homozygote, then the unknown genotype is heterozygote (Aa).</span>
B. Break down dead organisms
Fungi are decomposers. they breakdown the bodies of dead organisms. They play a very important role.
Answer:
I'm not really certain about this but my answer would be (a)
Answer: Please see expalnation column for answer
Explanation:Matching the following brain structures with its description gives
1.Arachnoid mater – Middle meninx
2. Subarachnoid space - located between the arachnoid mater and the pia mater.
3. Cerebral aqueduct - connects third ventricle and fourth ventricle.
4.Arachnoid villus -structure that projects through the dura mater into arachnoid mater
5. Pia mater - Meninx that follows every convolution of the brain.
6. First and second ventricles – Lateral Ventricles
7. Fourth ventricle - ventricle located between brainstem and cerebellum.
8. Apertures - passageway for cerebrospinal fluid between fourth ventricles and subarachnoid space
9.Third ventricle - ventricle associated with diencephalon.
10. Dura mater – Outermost meninx
11. Interventricular foramina - Connects the lateral ventricle and third ventricle
12. Superior sagittal sinus - Collects venous blood and cerebrospinal fluid.
