Correct Answer: D. seed-germination

Correct Answer: D) Arthopoda

Explanation

The question is asking about the largest phylum in the animal kingdom. A phylum is a group of organisms that share common characteristics. The options are Cnidaria, Mollusca, Chordata, and Arthropoda. Cnidaria is a phylum that includes animals like jellyfish and corals, which have stinging cells called cnidocytes. Mollusca is a phylum that includes animals like snails, clams, and octopuses, which have soft bodies and often have a hard shell. Chordata is a phylum that includes animals like fish, birds, and mammals, which have a notochord (a flexible rod-like structure) and a dorsal nerve cord. The correct option is D, Arthropoda. This phylum includes animals like insects, spiders, and crustaceans, which have jointed legs and a hard exoskeleton. Arthropoda is the largest phylum in the animal kingdom, with over one million known species. So, to summarize, the question is asking for the largest phylum in the animal kingdom and the correct answer is Arthropoda, which includes animals like insects and spiders.

Correct Answer: D. 90^o and 60^o

Correct Answer: B. rubber

Correct Answer: D. 23

Explanation

\(T_{n} = a + (n - 1)d\) (for a linear or arithmetic progression)

Given: \(T_{n} = 71, a = -6, d = -2\frac{1}{2} - (-6) = 3\frac{1}{2}\)

\(\implies 71 = -6 + (n - 1)\times 3\frac{1}{2}\)

\(71 = -6 + 3\frac{1}{2}n - 3\frac{1}{2} = -9\frac{1}{2} + 3\frac{1}{2}n\)

\(71 + 9\frac{1}{2} = 3\frac{1}{2}n \implies n = \frac{80\frac{1}{2}}{3\frac{1}{2}}\)

\(= 23\)

Correct Answer: C) 90o

Correct Answer: D. the institutions of the state

Explanation

A government is the system or group of people governing an organized community, often a state. In the case of its broad associative definition, government normally consists of legislature, executive, and judiciary.

Each government has a kind of constitution, a statement of its governing principles and philosophy. Typically the philosophy chosen is some balance between the principle

Correct Answer: D. parthenocarpic

Correct Answer: B. \(\frac{2V}{r}\) - 1

Explanation

F = \(\frac{r}{2}\) and v = mu

F = \(\frac{UV}{U + V}\)

\(\frac{r}{2}\) = \(\frac{U \times mu}{U + mu}\)

\(\frac{r}{2}\) = \(\frac{mu^2}{u(1 + m)}\)

\(\frac{r}{2} = \frac{mu}{1+m}\)

\(\frac{r}{2} = \frac{v}{1+m}\)

\(\frac{2v}{r} = 1+m\)

\(m = \frac{2v}{r} - 1\)

Correct Answer: C. a schemer
