Answer:
Double fertilization
Explanation:
The phenomenon of double fertilization is unique to flowering plants (i.e., angiosperms). Each pollen grain produces two male gametes (sperm cells), one of which fertilizes the egg to form the zygote, whereas the other sperm fuses with polar nuclei in the female gametophyte in order to form a triploid cell (3n) called endosperm. Subsequently, this endosperm will support embryonic growth by supplying storage nutrients and by serving as a mechanical barrier during seed development and germination.
I'm pretty sure:
a) pepsin optimal pH: 3 and lipase optimal pH:8
b) No, because the stomach needs to be acidic and have an acidic pH but lipase is considered alkaline because its optimal pH is between 8-14 meaning it's an alkaline.
Not sure if this is any help but I hope it helped a little bit! :)
Each of the term is identified whether they arise from the ectoderm, mesoderm or the endoderm.
The thyroid arises from the endoderm.
The thymus arises from the ectoderm.
The anterior pituitary arises from the ectoderm.
Answer:
<em>hazardous waste container</em>
Explanation:
In a lab, hazardous waste container contains all the waste which can be dangerous or infectious. Hence, it should be properly handled and disposed of. Due to the cut in the lab, the blood of Lousia might contain infectious microorganisms. Hence, after cleaning the blood with paper towels, the paper towels should be discarded in the hazardous waste container as the paper towel might contain hazardous microorganisms.
The most common example that determines the similarities in anatomical features among organisms is the bone structure, commonly used in comparative anatomy. For example, the forelimbs or appendages of bats, humans, cats and whales have the same basic parts but they differ in function. Fins of whales and wings of bats have the same skeletal parts, but fin is used for swimming while wing is for flight. These structures could be termed as homologous, analogous, or homoplastic. However, recent developments have been made than just basing to the skeleton - the main reason why we have comparative genomics today.
