<span>When compared with most fibres, sclereids are relatively short. Characteristic examples are brachysclereids or the stone cells (called stone cells
because of their hardness) of pears (Pyrus communis) and quinces
(Cydonia oblonga) and those of the shoot of the wax plant (Hoya carnosa)</span>
When blood calcium levels drop, glands embedded in the posterior thyroid secrete parathyroid hormone, which stimulates osteoclastic activity. It is made up of parathyroid glands that lie behind the thyroid glands. The reason why it is important because it controls calcium level in the blood and within the bones. It controlled by the low calcium levels in the blood it restorative parathyroid secretion whereas the high calcium levels in the blood stop the release of parathyroid hormone.
Answer:
A nominal scale describes a variable with categories that do not have a natural order or ranking. You can code nominal variables with numbers if you want, but the order is arbitrary and any calculations, such as computing a mean, median, or standard deviation, would be meaningless.
A nominal scale is a scale (of measurement) that uses labels to classify cases (measurements) into classes. Some examples of variables that use nominal scales would be religious affiliation, sex, the city where you live, etc. Example. One example of a nominal scale could be "sex".
For example, Race is a nominal variable having a number of categories, but there is no specific way to order from highest to lowest and vice versa.
Explanation:
Answer:
(c). Eukarya.
Explanation:
Prokaryotes are primitive, single-celled organisms that lacj complex membrane-bound cell organelles, such as nucleus, mitochondria, and endoplasmic reticulum.
Prokaryotes are grouped into two domains, including Archaea and Eubarteria. Archaea includes prokayotes that can live in extreme conditions are known as extremophiles, while domain Eubacteria includes all true bacteria.
Prokaryotes do belong to domain Eukarya as Eukarya includes all eukaryotic organisms.
Thus, the correct answer is option (C).
Answer:
answer is d
Explanation:
THe answer is D because this is dihybrid cross and we cross bwbw RR( normal red eye gene) x RR cncn. The F1 progeny has R in all locus of these genes so all will be R as heterozygous. When F1 progeny crossed, the 1/4 of bw cross and 1/4 of cn cross habe bwbw/cncn and will be white. So it will be 1/4x1/4 = 1/16
