Setler [38]2 years ago

Mutation result in changes in the nucleotides sequence in genes, so a mutation of the Pitx1 gene will change the nucleotide sequence in the gene.

<h3>What is a mutation?</h3>

A mutation refers to a change that occurs in the sequence of nucleotides in DNA molecules.

Since gene are regions of a DNA molecule that codes for a protein or gene product, a mutation will affect the gene product.

Therefore, for the Pitx1 gene, a mutation will change the nucleotide sequence in the gene.

RideAnS [48]

Answer: Those which can adapt and withstand the high acidity levels of water.

The pond slowly becomes more acidic due to release of chemicals from a nearby factory. The chemicals released are acidic and toxic which will cause biomagnification in the pond water. Those organisms which can withstand the high acidic pH of water will survive. Others which can undergo adaptations can also survive.

likoan [24]

The salivary glands, stomach, and pancreas secrete<u> lipase enzymes</u> to break down triglycerides into monoglycerides, fatty acids, and glycerol.

Lipases are a set of water-soluble enzymes that hydrolyze substrates such as triglycerides and phospholipids, have a similar structure and are essential in the metabolism of lipoproteins and lipids.

That is, the function of lipase enzymes is to hydrolyze triglycerides to generate diglycerides, monoglycerides, fatty acids and glycerol.

<u>About lipase enzymes</u>:

  • It acts on the neutral fats in the diet, splitting them into triglycerides or diglycerides and these to monoglyceride, which is the most easily absorbed fatty compound.

  • The action of lipase is much more manifest on triglyceride, and it is also much faster the higher the molecular weight of the fatty acid present.

  • It acts on the surface and in an aqueous medium, the emulsifying agent represented by bile salts is essential for optimum effectiveness.

  • They are widely distributed, with a presence in the animal and plant kingdoms and even in the simplest unicellular organisms.

Therefore, we can conclude that the salivary glands, stomach, and pancreas secrete lipase enzymes to break down triglycerides into monoglycerides, fatty acids, and glycerol.

love history [14]

Answer: The answer should be A: Precipitation.

Explanation: When we take a look at this question, it mentions that there is dew, fog, and clouds on the planet. Infiltration would have probably been evaporated from the ground and became a cloud. The dew and fog would be the condensation. The astronomers notice that there is never any rainfall, and precipitation in the water cycle is rainfall. So therefore, the missing part of the water cycle would be precipitation

which component of blood consists of cell fragments and is the main contributor to healing cuts? A. erythrocytes B. thrombocytes
il63 [147K]

Answer:

The correct answer would be B. thrombocytes.

Thrombocytes, also called platelets are the components of the blood which play important role in the process of hemostasis.

Hemostasis is the process of preventing the flow of blood from the damaged site or damaged blood vessel. It is the first stage involved in the healing of the wound.

Platelets form the platelet-plug at the site of damage which in turn activates another blood clotting factor fibrinogen.

Fibrinogen gets converted into an active fibrin (insoluble) which forms the meshwork like structure to trap more and more platelets and red blood cells. It results in the formation of a clot which completely seals the cut or damaged site.

Modern taxonomists primarily use which of the following to classify living organisms
-Dominant- [34]

The modern taxonomists classified organisms on the general basis of evolutionary, morphological, and genetic traits

Explanation:

  • Evolutionary relationships provides the phylogeny of evolutionary ancestors and descendants  
  • Homologous structures are structures which look the same but perform different functions , like bones of a human leg compared to bones on a bird's wing
  • Analogous structures have different structure but same function like an insect’s and a bird’s wing
  • Embryo developmental pattern and similar relationships
  • Similarities in DNA and protein sequencing in related organisms

The above basis provided modern taxonomists to classify organisms according to the various disciplines like Genetics, Cytology, Embryology, Physiology, Anatomy and many more.
