Correct Answer: D. Spiracles

Correct Answer: A. eye colour and body weight

Correct Answer: C) cone

Explanation

This Biology question is asking you to complete an analogy. The first part of the analogy is Flower is to the angiosperm. The word angiosperm refers to plants that have flowers and produce seeds enclosed in a fruit. Therefore, a flower is a characteristic feature of angiosperms. The question then asks you to complete the analogy by choosing the option that is to gymnosperm what a flower is to angiosperm. Gymnosperms are plants that produce seeds without fruits or flowers. They usually have cones and needle-like leaves. The options given are pines, cords, cone and anther. From this, we can see that the correct option is cone. This is because cones are a characteristic feature of gymnosperms, just as flowers are a characteristic feature of angiosperms. It is important to note that pines are a type of gymnosperm, but not all gymnosperms are pines. Therefore, option A is not the correct answer. Options B and D are not related to gymnosperms or their characteristic features, making them incorrect options. To summarize, the correct answer to this Biology question is option C, cone, as it is to gymnosperm what a flower is to angiosperm.

Explanation

(a) Main parts of human brain are:

(a) The forebrain/ Comtractile cerebrum

(b) The midbrain/cerebellum

(c) The vacuole hindbrain/medulla oblongata

(b)(i) The cerebrum is the seat of consciousness and senses. It also Paraniyium functions in the following ways: intelligence, memory, gcanuies judgement, learning, imagination and voluntary Chicroplost actions. It collects and stores information.

(ii) Hypothalamus

(a) connects the pituitary gland or master gland to the thallamus

(b) It contains the reflex centres.

(c) It regulates body temperature.

(d) It regulates water balance and osmoregulation.

(e) It controls sleep and wakefulness.

(f) It controls blood Of drinking

(h) It is the seat of aggression and anger; pressure.

(g) It is the centre for appetite, feeding and It controls the pituitary gland. It controls speech.

(iii)(a) Medulla oblongata controls breathing and respiration;

(a) It controls heart-beat

(b) It controls digestion.

(c) It controls size of blood vessels.

(e) It controls the secretion of saliva.

(f) It controls laughing.

(g) It controls involuntary actions such as sneezing, blinking, coughing, yawning etc.

(c)(i) Organs of higher plants that respond to stimuli are:

(a) Flowers

(b) Leaf

(c) Root

(d) Stem

(e) Tendril

(ii) Tactic movement is the locomotion, and response of the entire body of an organism in response to a stimulus. It is directional; locomotion could be positive or negative.

(d)(i) Phototaxis is the movement in response to light stimulus. it is the source of light by organisms. E.g. Euglena moving away from light

(ii) Hydrotaxis is the response of a whole organism to the stimulus of water or humidity. E.g. Woodlouse moves towards areas of high humidity.

(iii) Chemotaxis is the movement of an organism in response to a chemical stimulus; E.g. Amoeba and Paramecium moving away from chemicals.

Correct Answer: B. physiological

Correct Answer: C. raising the mortalility rate

Correct Answer: D. Taiga

Explanation

The taiga biome is the largest biome in the world and is characterized by short, rainy summers coupled with long, freezing winters. Due to its extremely cold temperatures, the taiga's flora or plant life consists of mostly coniferous trees that can survive on the scarce nutrients available in the cold climate of the biome. In contrast, the tundra is frozen year-round and permafrost prevents any trees from growing. Deciduous forests, as the name suggests, sports mainly deciduous trees as its plant life. The alpine biome consists mostly of the areas right below the snow lines of mountains and is generally dry year-round. The chaparral is a relatively small biome that is characterized as being mostly hot and dry year-round, with mild winters.
