Answer: Option A.

Explanation:

A greenhouse is defined as a structure that contains walls and roof made up of  transparent material like glass or plastic, under which climatic condition is maintained for the regular growth of plants inside it.

In a greenhouse, best position for pant is maintained so that exposure of sunlight should be in its optimal range.

This is so because there must be adequate amount of sunlight falling on the plant for its proper growth and development because more or less than normal amount of sunlight is not good for plants.

Hence, a plant in greenhouse should be positioned so that it's exposure to sunlight would be  within its optimal range.

Why are raptors a indicator species?
Arturiano [62]
Indicator species may provide useful substitute for large scale surveys to monitor biodiversity. Weconducted surveys in the Afro-alpine habitats of the Bale Mountains National Park (BMNP) with theobjective of identifying indicators for the species richness of the raptor guild. Raptors were countedby scan sampling technique from a suitable vintage point. Three classes of 18 sample units groupedaccording to the variability of the moorland ecosystem in the magnitude of process variables importantfor raptor species richness were used in determining the indicator value of species as a function of their abundance concentration and the percentage of species occurrence per sample group. Thisprocedure determined indicator values for all species in the resident raptor community. Comparisonwith randomly expected values demonstrated that only<span> Aquila verreauxii</span>and<span> A. chrysaetos</span>haveindicator values that were significantly larger than the randomly expected values. The species richnessestimated using the abundances of these two species predicted the observed species richness of thewhole community in a linear regression model that explained 66% of the deviance in the data set.Furthermore, the species richness of the community predicted by process variables had correlation of very high significance with that predicted by the indicator species. We have thus identified twoindicator species to a raptor guild of the BMNP and demonstrated that these two species encapsulatedmost of the information regarding the species richness response of the guild to key process variablesin the Afro-alpine moorland ecosystem. Our findings contribute significantly to current and futureefforts of monitoring the biodiversity of the park providing a cheap and quick means of data generation<span>relevant for making management decisions.                               Hope this helped! :)</span>

Alchen [17]

Answer:

The correct option is - D

The probability that the test rejects H₀ when m = 1 is true.

Explanation:

Given,

The significance level of a test

H₀ : m = 1 versus Hₐ : m > 1

Given options were

A) the probability that H₀ is true.

B) the probability that the test fails to reject H₀ when m = 3 is true.

C) the probability that the test rejects H₀ when m = 3 is true.

D) the probability that the test rejects H₀ when m = 1 is true.

Therefore, D means that The alternative hypothesis (Hₐ) will reject the Null hypothesis (H₀) when m = 1.

Choose the term that identifies the type of bond that joins amino acids in proteins
ikadub [295]
Amino acids in proteins are linked to one another by peptide bonds between the carboxyl group of one amino acids and the amino group of another. 

Amino Acids has an important role both in building blocks of proteins and as in-between in metabolism. Amino acids also used in every cell of your body to build the proteins you need to survive. A carboxyl group is made of one carbon and two oxygen atoms. Amino acids bond together to make long chains, those long chains are called proteins.
