1 answer:

5 0

Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. Land use by humans has a long history, first emerging more than 10 thousand years ago. It has been defined as "the purposes and activities through which people interact with land and terrestrial ecosystems and as "the total of arrangements, activities, and inputs that people undertake in a certain land type. Land use is one of the most important drivers of global environmental change.

Which organisms are not examples of an adaptive radiation?

gavmur [86]

Answer:

Option B, Mammals and reptiles in the post-dinosaur age.

Explanation:

Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.

Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.

Hence, option B is correct

In one type of plant, orange petals (O) are dominant over yellow petals (o) and tall stems (T) are dominant over short stems (t)

vodka [1.7K]

Answer No 1:

The set up of the punnet square is shown in the attached diagram. As the alleles assort independently hence the gametes formed will be OT,Ot,OT,Ot and OT,Ot,oT,ot. These will be the outcomes of the possible gametes formed. When these gametes are cross bred, the results are shown in the diagram attached.

Answer No 2:

The outcomes of each possible genotype are:

OOTT = 2/16

OOTt = 4/16

OOtt = 2/16

Oott = 2/16

OoTT = 2/16

OoTt = 4/16

Answer No 3:

The likelihood of each possible offspring phenotype is:

Orange petals with tall stem and orange petals with small stems present in ratio 12:4 i.e. 3:1.

In photosynthesis what form of energy is sunlight converted two major reactions that take place

Arte-miy333 [17]

Sunlight emits light energy which is absorbed by the thylacoids in the chloroplasts of a plant. Chloroplasts are organelles in a plant cell whose funtion is photosynthesis (the use of light to make energy). Thylacoids are a part of the chloroplast which absorbs light. The thylaciods convert the light into energy molecules NADPH and ATD. The Calvin cycle then takes place in the stroma (gellatinous matrix of the chloroplast). The Calvin cycle is the use of ATP and NADPH plus carbondioxide to produce starch. Starch is the polysaccharide sugar formed from glucose synthesized in a linear chain. The starch is the storage of the glucose which is used as an energy source for the plant cells.
