Answer:
C) they lack lignified vascular tissue. (
Since they do not have vascular tissues, they are not able to develop vertically like the trees we know.)
Explanation:
A)
Plants do not have "sperm". They have sporophytes or gametophytes.
B) No specific parasitic bacteria of bryophytes are known.
D) In fact, they have. Although they require water for their reproduction, some species of bryophytes are found in deserts.
E) Rhizoids are not weak, otherwise they would not have the ability to keep bryophytes attached (mosses).
Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.
Answer:
a. DNA carries instructions for the functions of every cell and enzyme in living organisms.
b. DNA can serve as a way to identify one individual from another.
Explanation:
Which of the following is TRUE about DNA?
a. DNA carries instructions for the functions of every cell and enzyme in living organisms.
b. DNA can serve as a way to identify one individual from another.
c. All living organisms can carry DNA in practically every cell of their body
The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.
- The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
- Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
- For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.
Therefore, gluconeogenesis conserve more energy.

Arthritis is a joint disorder involving joint inflammation.Pain is often localized to only the affected joint. Osteoarthritis is a wear and tear type of arthritis often affects aging population affecting joints in hands,knees and lower back. Heberden's node is an example and develops around middle age thus Wendell might have this.
