Amino acids. These class of compounds are considered the building blocks of most organisms, and around 500 of these are known and indentified. All proteins, carbohydrates, and nucleic acids are polymers ("many units") and each unit is an amino acid.

Advocard [28]

A translocation that moves a gene from an area of euchromatin to heterochromatin would typically cause a(n) reduction in the expression of the gene.

<h3>What is euchromatin?</h3>
  • A kind of chromatin that is sparsely packed, enriched in genes, and frequently engaged in transcription is called euchromatin.
  • Contrasting with heterochromatin, which is compact and less accessible for transcription, is euchromatin.
  • The human genome has 92% euchromatic DNA.
<h3>What is heterochromatin?</h3>
  • Heterochromatin, often known as condensed DNA or densely packed DNA, has many different types.
  • Between constitutive heterochromatin and facultative heterochromatin, these variations fall on a spectrum. Both contribute to how genes are expressed.
  • Eukaryotic genomes contain heterochromatin, which serves a variety of purposes including regulating gene expression and preventing DNA replication and repair.

Ash trees are being removed when they show signs of the ash borer, a parasite that affects the trees and kills them off. What be
guajiro [1.7K]
<span>The ash trees are being cut when the show signs of infestation of the ash borer. Ash borer in particular the Emerald Ash Borer (EAB) is a tiny bug but can really do a great damage to the tree. When the tree is infested with the ash borer, they lay their eggs in the bark of tree, when the eggs hatch the lavas would start eating on the inner tissues of the tree blocking the flow of nutrients and water in the tree that causes the tree’s to death.  If the tree is infested they cut it down, burn and bury the wood to stop the spread of infestation. Ash trees are valued for its strength and elasticity that is often used to make baseball bats, bows, tool handles and other products that needs durable wood.</span>

Lipids commonly contain fatty acids. What are the two parts of a fatty acid? Check the correct answers below.
ch4aika [34]

Answer:

Hydrophillic head and a hydrophobic tail

Explanation:

Every fatty acid is composed of long chain of hydrocarbon tail. This hydrocarbon tail is nonpolar and insoluble in water. Hence this tail is labeled 'hydrophobic'.

However, the head of the fatty acid contains polar COOH group which is capable of interacting with water, hence the head is hydrophillic.

Hence, a fatty acid is composed of a hydrophillic head and a hydrophobic tail.

Vedmedyk [2.9K]

Answer:

Answer is Calvin cycle.

Explanation:

Calvin cycle is very important to plants because it helps in the conversion of organic products for the usefulness of plants. This is because the carbon dioxide and water are converted to glucose, which is useful to plants.

Calvin cycle can be explained as the production of glucose through the use of chemical energy from NADPH and ATP, produced in light reactions, to convert the atmospheric carbon dioxide to RuBP, which is a five-carbon molecule.

Neither whales nor pythons have hind legs, but both have internal remnants of legs and hip bones. Snakes and whales must have I.
alexandr402 [8]

Answer:

I. evolved from ancestors that walked

Explanation:

Whales and pythons have vestigial structures, which are structures (hind legs) which are no longer useful to them since they have evolved. The ancestors of the whale and python did use the hind legs but over generations the whale and snake have adapted to new environments and they no longer need them.
