The answer is I, II, III and IV.  Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us. They may want to explore new ideas, gather evidence or prove or disprove previous results.

Answer:

The correct answer will be- options- I,II,III and IV.

Explanation:

The scientific investigation is the quest to understand and explain the natural phenomenon occurring in the surrounding environment.

The investigation is performed in three steps: descriptive, comparative and experimental investigation through the scientific method which uses the systematic approach to explain the phenomenon.

The investigations are done to understand and explain the phenomenon through observations, to test the predictions of the theories related to the phenomenon and discover and invent new things.

Thus, all the options are correct.

4After completing their study of the carbon cycle, three students wrote statements making claims related to this topic. Read eac
mario62 [17]

Answer:

Incorrects:

Claim 1: When forests are cleared, we take away an opportunity to remove carbon from the atmosphere.

Claim 2: Carbon moves through biological systems and returns to the atmosphere through photosynthesis.

Claim 3: The amount of carbon involved in rapid cycling is much less than 1 percent of the total amount of carbon on Earth.

Explanation:

  • The carbon contained in forest products makes a small and manageable contribution to the global carbon balance.  Globally, the net effect on atmospheric concentration is negligible, unless the rate of decomposition in geographically displaced product stocks is different from that in the forest ecosystem from which it was removed. However, controlling these rates through proper management can lead to some degree of mitigation of increases in atmospheric CO2.
  • During the carbon cycle, animals and plants release carbon dioxide into the atmosphere through cellular respiration, and plants capture carbon dioxide through photosynthesis.
  • The amount of carbon involved in rapid cycling it is the largest since it includes the carbon exchange between living beings, and is intertwined with the carbon cycle through long-term geological processes

hich of the following amino acids can contribute to the three-dimensional structure of a protein by forming covalent bonds with
ollegr [7]

Cysteine contributes to the three-dimensional structure of a protein by forming covalent bonds with an identical amino acid in another part of the protein.

<h3>What is the Cysteine Structure?</h3>
  • Covalent disulfide bonds form between the sulfhydryl (-SH) groups of cysteines in different parts of a protein are very important in determining the three-dimensional shape of the protein.
  • is a HOOC-CH-(NH2)-CH2-SH proteinogenic amino acid that is semi-essential. Cysteine's thiol side chain frequently functions as a nucleophile in enzyme processes.
  • The sign Cyz is occasionally used when a deprotonated catalytic residue is present.
  • The sign Cym can also be used to usually denote the deprotonated form.
  • The thiol is capable of being oxidized to produce the disulfide derivative cystine, which is crucial for many proteins' structural integrity. Cyx is sometimes used in this context. It carries the E identifier E920 when added to food.
  • The codons UGU and UGC encode the amino acid cysteine.
  • Cysteine and methionine, which contain sulfur, are more quickly oxidized than other amino acids.

If a mouse and a small lizard of the same mass (both at rest) were placed in experimental chambers under identical environmental
Harman [31]

The mouse, because it is an endotherm and therefore its basal metabolic rate is higher than the ectotherm lizard's standard metabolic rate.

<h3>What are endotherms and ectotherms?</h3>

Animals classified as ectotherms and endotherms employ several techniques to control body temperature.

Endotherms are recognized as warm-blooded creatures, whereas ectotherms are also referred to as cold-blooded creatures. Ectotherms and endotherms vary primarily in that endotherms control their body temperatures by sustaining bodily functions, but ectotherms depend on external sources like sunlight to do so. Ectotherms include invertebrates, fish, amphibians, and reptiles while endotherms include mammals and birds.

<h2>Cycads and Palm</h2>

Explanation:

The resemblance between cycads and palm trees is only superficial

  • Cycads are basically woody plants which have roots, a stem, leaves and reproductive structures known as cones
  • The main roots of cycads are thickened and fleshy and as they may have storage capacities they are often termed tuberous
  • Along with the fleshy stem they may have contractile properties which serve to regulate the level of the stem in the ground
  • Specialized, upright-growing, branched roots, known as coralloid roots, are also produced by all species of Cycads
  • The stems of cycads may be completely subterranean or emerge from the ground and be trunk-like
  • The leaves of most cycads are once-divided (pinnate) and often develop an attractive palm-like crown
  • Palm trees are a type of evergreen plant belonging to the Arecaceae family of plants
  • Palm trees have branch-less stems and large evergreen leaves
  • Generally, leaves of palm trees are either pinnate (feather-like leaves) or palmate (fan-like fronds)
  • Another way to identify the type of palm tree is by the trunk shape, some of the tallest species of palm trees have long slender single trunks and dwarf varieties have usually short fat palm trunks
  • Some smaller palm tree species may have clustered trunks with 3 or 4 short trunks growing together
  • There are also some dwarf palm trees that just have bushy pinnate fronds growing out the ground and don’t have any trunk at all
