Answer:
A) The male stamens hold the pollen, the female pistil holds the ovule, and the petals attract pollinators.
Stamens (male reproductive parts of a flower) collectively forms the male reproductive organ (androecium) in a flower whereas pistil (the female reproductive part of a flower) forms the female reproductive organ called gynoecium.
Stamen consists two parts that are anther (that produces pollens, male reproductive cells) and a stalk like structure called filament, which supports/ holds pollen producing anther.
The female pistil holds the ovule that is enclosed by ovary in flowering plants (angiosperms) and the petals in a flower attract pollinators.
Thus, option A) is the right answer.
<u>In law of superposition which layer is the oldest and which layer is the youngest?</u>
Law of superpostion is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy. In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. The oldest layer would be at the bottem because of how old it is and because of how much other elemnt has been coverd on it. The younges would be on top because it is newer and just got the in the last 100 years.

The correct answer is a sponge.
<span>A sponge (Porifera) is a multicellular organism which consists of two layers of cells and the mesophyll between them. Those cells are unspecialized and can transform into other types. The body of sponges is full of pores and channels which allow the water to circulate and thus to obtain food and oxygen.</span>
Differential heating is responsible for the wind patterns across the globe.
Differential heating is defined as the difference in heating of air on the land versus water. Sea breezes occur when land heats up faster than water which rises and creates a low pressure system. The high pressure air from the sea influxes is responsible for the creation of a sea breeze.
Unequal heating of the Earth's surface is responsible for the formation of large global wind patterns. Warm air rises at the equator and moves toward the poles while on the other hand, the cooler air rises at the poles and moves back toward the equator so in this way the earth’s global wind patterns occurs so we can say that differential heating is responsible for the wind patterns across the globe.

Answer:
D) Tropical dry forest
Explanation:
A biome is a geographical region on the Earth which comprises of similar type of fauna and flora in similar climatic conditions like temperature, precipitation.
The tropical rain forest is a unique biome which comprises of different types of climatic conditions in one biome like the region has both heavy rainfall as well as dry conditions and other climatic conditions. Because of this the flora and fauna have adapted themselves to live in such conditions and are called endemic species which are not found in the world anywhere.
The plants have adapted to survive dry conditions by showing the adaptation of xerophytic plants and some could store water during heavy rains for the dry season.
Thus, Option-D is the correct answer.
