<span>The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation. In the Gymnosperms and flowering plants (Angiosperms), the sporophyte generation is the most prominent phase, comprising the familiar green plant with its roots, stem, leaves and cones or flowers. In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.</span>

Which of the following statements is true regarding anabolism?

navik [9.2K]

Answer:

B) In anabolism, larger molecules are made from smaller molecules.

Explanation:

Anabolism is a metabolic process that uses up energy that is produced to build up complex and larger molecules from smaller ones. It is part of the chemical process that takes place in a cell.

For example, photosynthesis is an anabolic process, in which the cell forms larger molecules such as glucose from smaller molecules like water and carbon dioxide, with the use of solar energy.

Option B is true regarding anabolism.

Active Immunity is natural.

Passive Immunity is maternal.

Active Immunity from Vaccination.

Passive Immunity is Artificial.

Passive Immunity:

Does not require previous exposure to a disease agent

Takes effect immediately

Does not last long (up to a few months)

Active Immunity is produced inside of the body, whereas passive immunity is introduced from outside of the body.

Active Immunity is from direct infection and vaccination.

Passive Immunity is from Breast milk, Injection, Mother to baby through the placenta.

Active Immunity takes effect over time (typically several weeks).

Passive Immunity takes effect immediately.

Active Immunity's length of efficacy is Long-term to lifelong.

Passive Immunity is short-term.

Active Immunity is produced by memory cells, Passive Immunity is not.

Which statement describes how pioneer species and climax communities are different?

Lorico [155]

Answer: D). Primary species have large numbers of offsprings, and climax communities contain species that have small numbers of offsprings.

An ecological succession is a process of gradual changes occurs in a biological community with respect to changes in the non-living abiotic factors (water, air and sunlight) and with respect to time until the ecosystem attains stability. Primary or pioneer species are the species which invade the previously barren and primitive landmass for their survival. These species make the environment suitable for the growth of other species. These grow and develop in the initial stages of succession. These species are simple organisms which reproduce asexually and produces large number of offsprings. Examples are lichen and moss. Lichen grows on the surface of rocks and acids released by them causes withering of rocks into soil which facilitate the growth of mosses and other plants. Climax community develops in an ecosystem after replacing many previously inhabiting species. Climax community develops in the end of the ecological succession. It contains species which are highly complex and uses sexual reproduction for the production of offsprings which are less in number as compared to those produced by pioneer species by asexual reproduction.

The bees wing are moving very fast the best wings are much smaller than it body ?

marishachu [46]

Explanation:

It is true that the wings of the bee move very fast. The wings are smaller than their body and it is believed to be difficult for the wings to lift the whole body of the bee.

Sometimes, bees carry nectar and pollen with itself which again increases their weight. It has been found that the wings do not move up and down rather moves to and from. Since air is denser, it tries to push the air downwards and lift itself upwards.
