Explanation:

The complementary for A is T (visa versa)

The complementary for G is C (visa versa).

So we just have to put the complementary for each letter to get the complementary strand.

Explanation:

Heterotroph means energy is made through consuming another organism.

Autotroph means energy that is made through producing by itself.

A plant makes energy by itself

So a plant is an autotroph, so this statement is false.  

Answer:

Explanation:

Although no options was given, the explanation below should give detail explanation.

The Chemical  reactants(  internal factors) for the process of photosynthesis are C02 and H20, and enzymes. Other external factors  are sunlight and chlorophyll.Therefore for a plant to undergo photosynthesis these reactants must be present in the presence of sunlight.

In the present scenario the plant in the test tube exposed to sunlight must used up the C02  with water and exposed sunlight to produce O2 -the by products and  CHO,Protein and Lipids in plants.

Since the C02 has  metabolised,no CO2 would be present in the test tube  of the plant and the water, hence BTB is negative,blue- no C02.

However,the plants in the dark lacks  the supply  of  sunlight therefore no photosynthesis could occur.Consequentially the C02 is not metabolized,and its concentration is high in the leaf in the test tube placed in the dark.This is indicated as yellow positive by the BTB which change from Blue to yellow.

Answer:

The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.

Explanation:

The nucleus controls and regulates the activities of the cellular (e.g., growth and metabolism) and carries the genes and systems that include the hereditary statistics.

The nucleus has 2 primary features: it's miles responsible for storing the cell's hereditary cloth or the DNA. it is liable for coordinating the various essential cell activities along with protein synthesis, cellular division, growth, and a bunch of other critical features.

Answer:

Process of the cells, tissues, organs, and organ systems all working together to maintain a stable internal environment are best defined by the term homeostasis (option B).

Explanation:

All living organisms perform their functions properly by maintaining some conditions of the internal environment constant, such as temperature, pH and amount of water or electrolytes. This also guarantees a healthy state and a longer life.

The maintenance of the organic balance is done by an internal regulation system, called homeostasis. Homeostasis means all the processes aimed at preserving the balance and fulfilling the organic functions properly.

The other options are not correct because:

    A. Digestion is the process by which nutrients are converted into small molecules that are easily absorbed by the body.

    C. Excretion is the process of eliminating waste from metabolic and organic processes.

    D. Disequilibrium is the term applied to the failure or loss of ideal conditions or balance.

Explanation:

Answer:

The light-dependent reactions produce ATP and NADPH, which are then used by the light-independent reactions.

Light-dependent reactions and light-independent reactions both produce each set of sugars, and working together they produce more sugars than they can produce separately.

Light-dependent reactions which convert light energy into chemical energy, so the goal of the light-dependent reactions of photosynthesis is to collect energy from the sun and break down water molecules to form ATP and NADPH, while these two energy storage molecules occur which is used in light-independent reactions.

Light-dependent reactions occur in the thylakoid membrane that use light energy to make ATP and NADPH while in light-independent reactions or the Calvin cycle where electrons activated from light-dependent reactions provide energy to make carbohydrates from carbon dioxide molecules.

Thus, Light-dependent reactions and light-independent reactions both produce each set of sugars, and working together they produce more sugars than they can produce separately.

Answer: B. Primary Succession

The question is incomplete. Here is the complete question.

Three red square pieces of wood, four yellow square pieces, and five boue square pieces are put into a cloth bag. four re round pieces, two yellow round pieces, and three blue round pieces are also put into the bag. All the pieces are then mixed about. Suppose someone reaches into the bag (without looking and without feeling for a particular shape piece) and pulls out one piece.

What are the chances that the piece is red round or blue round piece?

a. Cannot be determined

b. 1 chance out of 3

c. 1 chance out of 21

d. 15 chances out of 21

e. 1 chance out of 2

Because:

a. 1 of the 2 shapes is round

b. 15 of the 21 pieces are red or blue

c. There is no way to tell which piece will be picked

d. Only 1 of the 21 pieces is picked out of the bag

e. 1 of every 3 pieces is a red or blue round pieces

Answer: b. 1 chance out of 3

              e. 1 of every 3 pieces is a red or a blue round pieces

Explanation: Inside the bag, there will be:

The question is asking for a round red piece. The probability of that happening is

P(r) = [tex]\frac{4}{21}[/tex]

And a blue round piece:

P(b) = [tex]\frac{3}{21}[/tex]

It is a "OR" probability, so:

P(r or b) = [tex]\frac{4}{21} +\frac{3}{21}[/tex]

P(r or b) = [tex]\frac{7}{21}[/tex] or [tex]\frac{1}{3}[/tex]

Which means 1 out 3 pieces taken out of the bag will be red or blue.
