Answer:
<em>Monocot stems have scattered vascular tissue, whereas eudicots stems have vascular tissue arranged in a ring.</em>
Explanation:
Both monocots and eudicots belong to the plant's sub-division known as angiosperms. However, there are four distinguishing features between the two:
- Monocots have single cotyledons or seed leaves while eudicots have two.
- Monocots usually produce needle-like leaves with parallel veination while eudicots produce broad leaves with net veination.
- Root system in monocots is usually a tap root while it is fibrous root in eudicots.
- Floral parts in monocots are usually in multiple of threes while they are in multiples of fours of fives in eudicots
- Vascular bundles in the stems of monocots are usually scattered about while they are arranged in ring-form in eudicots.
<em>Hence, the only true one among the statements is that monocots stems have scattered vascular tissue, whereas eudicots stems have vascular tissue arranged in a ring.</em>
Photosynthesis, which is the process through which some living organisms, including most plants and some fungi, make their own food, produces oxygen as a waste product.<span> The process of photosynthesis in plants is the reverse of the respiration process in humans. While humans breathe in oxygen and expel carbon dioxide, plants ingest carbon dioxide and dispel oxygen.</span>
The correct answer for the question that is being presented above is this one: "b. has a much lower rate of primary productivity." Compared to an ecosystem with just a single stage of succession, an ecosystem with a variety of successional stages <span>b. has a much lower rate of primary productivity.</span>
Answer: Telomeres, Helicases, Okazaki, DNA polymerase, Topoisomerase
Explanation:
1. Telomeres these are set of repetitive nucleotide sequence found at the end of a linear chromosomes they help preventing the DNA chromosome frrom sticking to other DNA chromosomes.
2. Helicases are proteins that uses energy (ATP) to unwind DNA strands during replication.
3. Okazaki fragments the small DNA nucleotide sequence synthesized separately on the lagging strand.
4. DNA polymerase are enzymes that catalyzes the addition of deoxyribonucleotides to DNA during replication.
5. Topoisomerase are enzymes that prevent single stranded DNA from supercoil, rumple and winding back during replication.
Answer: a. Heritability research is able to identify genes for particular behavior patterns.
Explanation:
Heritability is the ability of a trait to move from one generation to another. Heritability, sum of phenotypic (observable) variability that is due to human genetic variations in a population.
Heritability, in a general sense, is the ratio of variability for a trait or character in a population due to variations between genotypes and the overall phenotypic variation.
Hence, as genes identification is are the basis of heritability research, option "a" is incorrect.
